 1. Identify every caller-controlled id that crosses into a data read or mutation.
-2. Revalidate ownership or membership at the sensitive operation boundary, not just at route entry.
-3. Use the dedicated active-scope validators instead of raw settings reads and writes.
-4. Rebind plugin scope parameters to the authorized request context before storage, blob, or Cosmos access.

+3. Revalidate ownership, membership, or another explicit relationship at the sensitive operation boundary, not just at route entry.
+4. For reverse lookups from opaque IDs to identity metadata, verify that the endpoint does not become a user-enumeration or app-membership oracle.
+5. Use the dedicated active-scope validators instead of raw settings reads and writes.
+6. Rebind plugin scope parameters to the authorized request context before storage, blob, or Cosmos access.

+# Local Browser Runtime Assets
+
+## Critical Requirement
+
+Never load browser runtime JavaScript from the public Internet. If SimpleChat uses a JavaScript library, framework, worker script, module, import map, or plugin runtime in the browser, keep a pinned local copy in the repository and serve it from the SimpleChat app.
+
+This rule also applies to browser companion assets that are required by JavaScript libraries, including CSS, fonts, source maps, worker files, WebAssembly files, dictionaries, and library-managed fallback downloads.
+
+## Required Pattern
+
+- Store third-party browser assets under an appropriate local static path, such as `application/single_app/static/js/<vendor>/` or `application/single_app/static/css/<vendor>/`.
+- Reference browser assets with local static paths, preferably through `url_for('static', filename='...')` in templates.
+- Pin the library version in the filename, folder name, documentation, or related test when the upstream asset is copied locally.
+- Preserve required third-party license or attribution files when vendoring assets.
+- Disable library options that auto-download extra browser assets unless those extra assets are also available locally.
+- Keep Content Security Policy `script-src` and `style-src` aligned with local assets; do not loosen CSP to allow a CDN for browser runtime code.
+
+## Disallowed Patterns
+
+Do not add runtime browser references to:
+
+- CDN-hosted scripts or modules, such as `cdn.jsdelivr.net`, `unpkg.com`, `cdnjs.cloudflare.com`, `esm.sh`, `skypack.dev`, `code.jquery.com`, or `stackpath.bootstrapcdn.com`.
+- Remote CSS for JavaScript-driven widgets when a local copy is expected.
+- Library defaults that inject remote `<script>` or `<link>` tags.
+- Dynamic imports from public Internet URLs.
+- Worker, source map, WASM, dictionary, font, or plugin URLs hosted outside the SimpleChat app.
+
+## Validation Checklist
+
+When adding or changing browser assets:
+
+1. Search templates, static JavaScript, static CSS, and relevant Python-rendered frontend routes for new external asset URLs.
+2. Confirm all browser JavaScript dependencies are served from `/static/...` or `url_for('static', ...)`.
+3. Add or update a regression test when fixing an external asset dependency.
+4. Run a syntax check for changed JavaScript files, such as `node --check <file>`.
+5. Run `git -c core.whitespace=blank-at-eol,blank-at-eof,space-before-tab,cr-at-eol diff --check` before finishing.
+
+## Allowed Network Calls
+
+This rule does not prohibit authenticated API calls, application data fetches, server-side Azure service calls, proxied map tile requests, user-requested links, or documentation-only examples. It specifically prohibits loading browser runtime code and required companion assets from public Internet CDNs.

+# Deployer Version Management
+
+When a change modifies files under `deployers/`, include an update to `deployers/version.txt` in the same change.
+
+## Rules
+
+- Keep the deployer version separate from `application/single_app/config.py`.
+- `deployers/version.txt` must contain only a plain semantic version string in the format `X.Y.Z`.
+- Default to a patch increment when a deployer change is made: `1.0.0` -> `1.0.1`.
+- Use a minor or major increment only when the deployer workflow or CI/CD compatibility contract changes intentionally.
+- If the only deployer file being changed is `deployers/version.txt`, do not add an extra bump beyond the intended version update.
+
+## Applies To
+
+This rule covers deployer scripts, `azure.yaml`, `.azure` environment helpers, Bicep/Terraform deployer files, and other deployment workflow assets under `deployers/`.

+---
+
+Audit the requested SimpleChat code for Broken Access Control, IDOR, and BOLA-style issues. Focus on places where caller-controlled object identifiers cross into reads, writes, search queries, blob access, plugin calls, or profile/settings lookups without a fresh authorization decision for that exact object.
+
+Use the repository guardrails in [.github/instructions/broken-access-control-prevention.instructions.md](../instructions/broken-access-control-prevention.instructions.md) and the deterministic checker in [scripts/check_broken_access_control.py](../../scripts/check_broken_access_control.py). If the user did not provide target paths, start with changed files and likely surfaces under `application/single_app/route_backend_*.py`, `application/single_app/route_external_*.py`, `application/single_app/functions_*.py`, and `application/single_app/semantic_kernel_plugins/`.
+
+## Audit Workflow
+
+1. Identify entry points: Flask routes, Semantic Kernel `@kernel_function` methods, background task dispatchers that accept request-derived IDs, and helpers called by those surfaces.
+2. Trace each object identifier from source to sink. Treat route path parameters, request JSON, query args, form values, active settings, hidden fields, plugin arguments, client state, and datastore-provided owner/participant IDs as untrusted until proven otherwise.
+3. For each sensitive sink, verify an authorization decision at or immediately before the sink. Sensitive sinks include Cosmos `read_item`, `query_items`, `upsert_item`, `delete_item`, blob reads/writes, Azure Search operations, Graph calls that reveal identity data, file downloads, profile images, conversation messages, documents, groups, public workspaces, and user settings.
+4. Distinguish role checks from object checks. `@login_required`, `@user_required`, `@admin_required`, GUID entropy, Graph search availability, and frontend-only access are not sufficient for object-level authorization.
+5. Look for reverse-resolution or oracle behavior: endpoints that turn known opaque IDs into names, emails, profile images, app membership, document ownership, conversation membership, or existence signals.
+6. Compare the implementation against approved helper patterns such as `_authorize_personal_conversation_read(...)`, `_authorize_personal_conversation_access(...)`, `_authorize_user_profile_access(...)`, `_read_authorized_user_profile_document(...)`, `get_user_settings(...)`, `assert_group_role(...)`, `require_active_group(...)`, `require_active_public_workspace(...)`, `_resolve_authorized_scope_arguments(...)`, `_resolve_blob_location_with_fallback(...)`, and `_resolve_authorized_fact_memory_call(...)`.
+7. Run the checker where useful:
+
+```powershell
+python scripts/check_broken_access_control.py --full-file <path1.py> <path2.py>
+```
+
+For a repository-wide audit, use the GitHub Actions workflow `Broken Access Control Full Scan` or run the checker over tracked Python files locally.
+
+## Output Format
+
+Return findings first, ordered by severity. For each finding include:
+
+- `Severity`: Critical, Important, Moderate, or Low.
+- `Surface`: endpoint/helper/plugin and file path.
+- `Source`: the untrusted object ID.
+- `Sink`: the protected data or mutation.
+- `Missing Check`: the absent ownership, membership, admin, or relationship validation.
+- `Impact`: realistic data or operation exposed.
+- `Remediation`: the specific helper or object-level guard to add.
+- `Regression Test`: the minimum test that should fail before the fix and pass after.

+# CSRF And State Changing Route Audit
+
+Audit SimpleChat state-changing Flask routes for CSRF exposure, unsafe HTTP methods, content-type assumptions, browser-triggerable mutations, and session boundary risks.
+
+Use the repository guardrails in [.github/copilot-instructions.md](../copilot-instructions.md), [.github/instructions/python-lang.instructions.md](../instructions/python-lang.instructions.md), [.github/instructions/broken-access-control-prevention.instructions.md](../instructions/broken-access-control-prevention.instructions.md), and [.github/instructions/santize_settings_for_frontend_routes.instructions.md](../instructions/santize_settings_for_frontend_routes.instructions.md). This prompt complements route authentication and broken access control audits; it does not replace object-level authorization review.
+
+## Operating Rules
+
+- Work in the SimpleChat repository root.
+- Treat POST, PUT, PATCH, DELETE, and any GET route with side effects as state-changing.
+- Treat browser cookies and Easy Auth sessions as ambient authority that may be sent automatically by the browser.
+- Do not revert unrelated user changes.
+- If the user asks for `scan only` or `stop after plan`, do not edit files.
+- If fixing findings, keep route behavior compatible with existing clients where possible and add focused tests.
+
+## Baseline Discovery
+
+1. Confirm the repo root, current branch, and concise `git status --short`.
+2. Inventory Flask routes and methods:
+
+```powershell
+rg -n "@app\.route|Blueprint\(|\.route\(|methods=|request\.(json|get_json|form|args|files)|session\[|session\." application/single_app/route_*.py application/single_app/*.py
+```
+
+3. Search for mutation verbs and side-effect helpers:
+
+```powershell
+rg -n "methods=\[.*(POST|PUT|PATCH|DELETE)|create_|update_|delete_|save_|set_|enable_|disable_|archive_|approve_|reject_|upload|download|run_|execute_|send_|start_|stop_|clear_|reset_" application/single_app
+```
+
+4. Search for GET routes that may mutate state:
+
+```powershell
+rg -n "@app\.route\([^\n]+methods=\[.*GET|@app\.route\([^\n]+\)" application/single_app/route_*.py application/single_app/*.py
+```
+
+Then inspect matched GET handlers for calls to create/update/delete/save/set/write/send/run/execute helpers.
+
+5. Search for CSRF-related helpers and tokens:
+
+```powershell
+rg -n "CSRF|csrf|WTF_CSRF|csrf_token|X-CSRF|SameSite|SESSION_COOKIE|CORS|Access-Control-Allow|Origin|Referer" application deployers docs .github
+```
+
+6. Run existing route and access-control checkers where useful:
+
+```powershell
+python scripts/check_swagger_routes.py <target-route-files>
+python scripts/check_broken_access_control.py --full-file <target-python-files>
+```
+
+## Manual Audit Checklist
+
+Review these areas:
+
+- Routes using GET for writes, state transitions, active workspace changes, downloads with side effects, task starts, deletes, approvals, admin toggles, workflow starts, or plugin/action execution.
+- State-changing routes that accept form posts, JSON, multipart uploads, query-string mutation parameters, or hidden fields.
+- Whether browser-callable mutations rely only on cookies/session without CSRF token, Origin/Referer validation, SameSite assumptions, or another explicit anti-CSRF boundary.
+- Routes intended for external APIs or webhooks that use bearer tokens, API keys, Easy Auth headers, or public callbacks instead of browser session cookies.
+- Content-Type assumptions: routes that call `request.get_json()` without checking JSON, accept `text/plain` or form-encoded bodies unexpectedly, or mutate based on query args.
+- Admin-only mutations exposed through browser forms or fetch calls.
+- CORS headers and preflight behavior that could allow cross-origin credentialed requests.
+- Idempotency and retry behavior for workflow starts, file operations, plugin calls, notifications, and external sends.
+- Settings updates, active scope writes, and session writes triggered by user-controlled IDs.
+
+## Triage And Plan
+
+Group findings before editing:
+
+- `Critical`: Cross-site browser requests can trigger sensitive admin or user mutations using ambient session credentials.
+- `Important`: State-changing routes lack a clear anti-CSRF boundary, use unsafe methods, or accept query/form data in risky ways.
+- `Moderate`: Content-type validation, SameSite/CORS assumptions, retry/idempotency, or external callback boundaries are unclear.
+- `Low`: False positives, non-browser external API routes with strong bearer auth, read-only routes, or reviewed exceptions.
+
+For each finding, record:
+
+- HTTP method and route path.
+- Function and file path.
+- Mutation or side effect.
+- Existing auth, object authorization, and CSRF-related boundary.
+- Missing guard or unsafe assumption.
+- Realistic impact.
+- Remediation approach.
+- Minimum regression test.
+
+## Remediation Patterns
+
+Use these fixes by default:
+
+- Move mutations off GET routes where compatible.
+- Require JSON or multipart content types explicitly for API mutations as appropriate.
+- Add or reuse CSRF token validation for browser-session form/fetch mutations where the app pattern supports it.
+- For non-browser external routes, require explicit bearer/API authentication and avoid session-cookie authorization.
+- Validate `Origin` or `Referer` only as a defense-in-depth measure, not as the sole boundary unless that is the established local pattern.
+- Keep object-level authorization checks at the mutation boundary.
+- Make retries idempotent or require operation IDs for side-effect-heavy workflows.
+- Add functional tests for unsafe method rejection, missing token rejection, or external-auth-only behavior.
+
+## Verification
+
+After fixing, run the narrowest reliable checks:
+
+- `python -m py_compile <changed-python-files>`.
+- Relevant functional tests under `functional_tests/`.
+- `python scripts/check_swagger_routes.py <changed-route-files>` for changed route files.
+- `python scripts/check_broken_access_control.py --full-file <changed-python-files>` when object authorization is involved.
+- Relevant UI tests when browser forms or fetch behavior changed.
+- `git -c core.whitespace=blank-at-eol,blank-at-eof,space-before-tab,cr-at-eol diff --check`.
+
+If a check cannot run locally, explain why and include the remaining risk.
+
+## Output Expectations
+
+Return findings first, ordered by severity. Include routes intentionally left public or external, any CSRF assumptions, files changed, validation commands run, skipped checks, and remaining risks.

+name: "Document Feature With Screenshots"
+argument-hint: "Feature name, routes/pages to capture, docs pages to update, optional viewport/zoom"
+agent: "agent"
+---
+
+Create or update SimpleChat documentation for a user-facing feature or release capability using browser screenshots and lightweight annotations.
+
+The user will describe the feature, where it appears in the app, and any release context. If critical details are missing, ask only the smallest number of clarifying questions needed to proceed.
+
+## Inputs To Gather
+
+- Feature or capability name.
+- User-facing workflow to show, including routes, pages, modals, tabs, settings, or roles needed.
+- Documentation destinations, if known.
+- Screenshot preferences, such as viewport size, browser zoom, or whether to use an existing logged-in browser session.
+- Privacy constraints, including names, emails, tenants, secrets, connection strings, document titles, or customer data that must be masked.
+
+## Documentation Targets
+
+- Feature documentation: `docs/explanation/features/[FEATURE_NAME].md`.
+- Latest release highlights: `docs/latest-release/` when the feature belongs in the current release showcase.
+- Main capability overview: `docs/features.md` when the feature is user-facing enough to appear in the public feature map.
+- Feature index: `docs/explanation/features/index.md`.
+- Screenshot assets: `docs/images/` using descriptive lowercase names, such as `feature-example-workflow.png`.
+- Release notes: check `docs/explanation/release_notes.md`; update only after confirming with the user when required by repo instructions.
+
+## Workflow
+
+1. Inspect the existing docs and feature implementation just enough to understand the feature and current conventions.
+2. Confirm the current app version from `application/single_app/config.py` for docs metadata. Do not bump the version for docs-only changes.
+3. Use the local app in an authenticated browser session when available. If the user provides viewport or zoom requirements, set them before capturing screenshots.
+4. Navigate the real workflow a user would follow. Prefer selectors, URLs, and Bootstrap APIs over fragile pointer clicks when modals, zoom, or tabs make hit testing unreliable.
+5. Before capturing screenshots, mask sensitive or distracting values in the DOM where possible instead of editing them into the final image later.
+6. Capture screenshots that show the feature clearly. Use focused element screenshots or clipped captures when full-page screenshots bury the important controls.
+7. Annotate screenshots with restrained callouts, boxes, and labels that identify the relevant controls or state. Keep the annotations readable at docs display size.
+8. Remove temporary raw screenshots and keep only the final documentation-ready assets.
+9. Update the relevant Markdown docs with concise user-facing copy, image references using `{{ '/images/name.png' | relative_url }}`, and implementation/version details where appropriate.
+10. Validate the changes:
+    - Confirm every referenced image file exists.
+    - Run Markdown diagnostics on edited docs.
+    - Run `git -c core.whitespace=blank-at-eol,blank-at-eof,space-before-tab,cr-at-eol diff --check`.
+    - Review a scoped `git status --short` and text diff for only the documentation and image files you touched.
+
+## Screenshot Quality Rules
+
+- Show the actual product workflow, not a marketing-style mockup.
+- Prefer one clear workflow image over several noisy images.
+- Make sure controls, labels, menus, selected options, preview states, and save actions are fully visible.
+- Avoid clipping the control that the documentation is explaining.
+- Use consistent annotation colors and label style across screenshots in the same documentation pass.
+- If the app contains real user or tenant information, mask it before the screenshot.
+- Do not include browser chrome unless it is needed to explain navigation.
+
+## Output Expectations
+
+At the end, summarize:
+
+- Which docs were created or updated.
+- Which screenshot assets were added.
+- What validation was run and whether it passed.
+- Any intentionally skipped work, such as version bumps or release notes updates.

+Use the repository guardrails in [.github/instructions/local_browser_assets.instructions.md](../instructions/local_browser_assets.instructions.md), [.github/instructions/xss-prevention.instructions.md](../instructions/xss-prevention.instructions.md), [.github/instructions/javascript-lang.instructions.md](../instructions/javascript-lang.instructions.md), [.github/instructions/html-lang.instructions.md](../instructions/html-lang.instructions.md), and [.github/copilot-instructions.md](../copilot-instructions.md). Do not add CDN-hosted browser runtime JavaScript or dynamic public-Internet imports.
+
+## Operating Rules
+
+- Work in the SimpleChat repository root.
+- Treat third-party browser JavaScript as part of the application attack surface, even when it is vendored locally.
+- Do not revert unrelated user changes.
+- If the user asks for `scan only` or `stop after plan`, do not edit files.
+- If fixing findings, vendor pinned local assets under `application/single_app/static/`, preserve license/attribution files, and keep CSP local-only.
+- Do not loosen CSP to permit public CDN runtime code.
+
+## Baseline Discovery
+
+1. Confirm the repo root, current branch, and concise `git status --short`.
+2. Find external browser runtime references:
+
+```powershell
+rg -n -i "https?://|//cdn|cdn\.jsdelivr|unpkg|cdnjs|esm\.sh|skypack|code\.jquery|stackpath|fonts\.googleapis|fonts\.gstatic|import\(|new Worker\(|workerSrc|wasm|sourceMappingURL|integrity=|crossorigin=" application/single_app/templates application/single_app/static application/single_app/*.py
+```
+
+3. Inventory local vendor assets:
+
+```powershell
+Get-ChildItem -Recurse application/single_app/static | Where-Object { $_.FullName -match "vendor|lib|third|openlayers|dompurify|marked|simplemde|bootstrap|jquery|chart|map|wasm|worker" } | Select-Object FullName
+```
+
+If PowerShell output is too noisy, use `rg --files application/single_app/static` and filter manually.
+
+4. Search CSP and security-header definitions:
+
+```powershell
+rg -n "Content-Security-Policy|script-src|style-src|connect-src|img-src|font-src|worker-src|frame-src|unsafe-inline|unsafe-eval|nonce|hash" application deployers docs .github
+```
+
+5. Search for third-party JavaScript sinks using the same XSS lens as first-party code:
+
+```powershell
+rg -n "innerHTML|outerHTML|insertAdjacentHTML|\.html\(|eval\(|new Function\(|document\.write|setAttribute\(\s*['\"]on|javascript:|postMessage|addEventListener\(\s*['\"]message|localStorage|sessionStorage" application/single_app/static
+```
+
+6. Run the deterministic XSS checker against changed or target JavaScript and template files where useful:
+
+```powershell
+python scripts/check_xss_sinks.py --full-file <changed-or-target-browser-files>
+```
+
+## Manual Audit Checklist
+
+Review these areas:
+
+- `<script>`, `<link>`, `import(...)`, module imports, import maps, workers, service workers, source maps, WASM files, dictionaries, fonts, maps, spell-check dictionaries, and plugin-managed fallback downloads.
+- Library configuration that fetches companion assets from public URLs at runtime.
+- CSP headers that allow CDN script/style/font/worker sources, `unsafe-eval`, broad wildcards, or broad data/blob allowances without a clear need.
+- Local vendor folders for version pinning, provenance notes, license/attribution files, minified and unminified copies, and update process clarity.
+- Vendored third-party JavaScript sinks that handle SimpleChat-controlled or user-controlled data.
+- Third-party library use of `innerHTML`, URL handling, markdown rendering, postMessage, workers, dynamic code execution, prototype modification, global object writes, storage, and network calls.
+- Whether a third-party asset has known security advisories, stale versions, abandoned maintainers, or safer local alternatives.
+- Whether vendored code is modified locally, and whether local modifications are documented enough to rebase safely during future upgrades.
+
+## Triage And Plan
+
+Group findings before editing:
+
+- `Critical`: Browser runtime JavaScript executes from a public CDN, remote dynamic import, remote worker, or compromised CSP path in a reachable application page.
+- `Important`: Vendored third-party JavaScript contains risky sinks reachable with untrusted SimpleChat data, or CSP is loosened enough to bypass local-only controls.
+- `Moderate`: Companion assets load remotely, version/provenance is unclear, licenses are missing, source maps leak unexpected code, or a library auto-downloads optional assets.
+- `Low`: Documentation-only external URLs, static user-clickable links, reviewed exceptions, or false positives.
+
+For each finding, record:
+
+- File and asset reference.
+- Asset source and whether it is first-party or third-party.
+- Runtime behavior and data trust boundary.
+- CSP impact.
+- Remediation approach.
+- Minimum regression test or static check.
+
+## Remediation Patterns
+
+Use these fixes by default:
+
+- Copy pinned browser runtime assets into `application/single_app/static/js/<vendor>/` or `application/single_app/static/css/<vendor>/`.
+- Reference assets through local Flask static paths such as `url_for('static', filename='...')`.
+- Keep required worker, WASM, font, dictionary, source map, CSS, and plugin assets local too.
+- Disable third-party library defaults that fetch remote companion assets unless the local equivalent is configured.
+- Keep CSP `script-src` and `style-src` aligned with local assets and avoid CDN allowlists.
+- Review third-party JavaScript sinks with the same checklist used for first-party XSS review.
+- Document vendored asset version, source URL, license, integrity/hash where practical, and local patches if any.
+- Add or update a functional test or static checker when fixing a remote asset dependency.
+
+## Verification
+
+After fixing, run the narrowest reliable checks:
+
+- `node --check <changed-js-file>` for changed JavaScript files.
+- `python scripts/check_xss_sinks.py --full-file <changed application JS/HTML/Python files>` when rendering surfaces changed.
+- Targeted `rg` searches for external URLs and CSP changes.
+- Relevant UI tests when a page’s assets or behavior changed.
+- `git -c core.whitespace=blank-at-eol,blank-at-eof,space-before-tab,cr-at-eol diff --check`.
+
+If a check cannot run locally, explain why and include the remaining risk.
+
+## Output Expectations
+
+Return findings first, ordered by severity. Include the list of local third-party browser libraries reviewed, any remote runtime assets found, CSP changes, vendored asset provenance gaps, validation commands run, skipped checks, and remaining risks.

+# File Upload And Document Ingestion Security Audit
+
+Audit SimpleChat file upload, document ingestion, blob storage, parsing, indexing, generated artifacts, downloads, citations, and document-derived browser rendering for security issues.
+
+Use the repository guardrails in [.github/instructions/broken-access-control-prevention.instructions.md](../instructions/broken-access-control-prevention.instructions.md), [.github/instructions/xss-prevention.instructions.md](../instructions/xss-prevention.instructions.md), [.github/instructions/local_browser_assets.instructions.md](../instructions/local_browser_assets.instructions.md), [.github/instructions/python-lang.instructions.md](../instructions/python-lang.instructions.md), and [.github/copilot-instructions.md](../copilot-instructions.md).
+
+## Operating Rules
+
+- Work in the SimpleChat repository root.
+- Treat filenames, file metadata, MIME types, parser output, extracted text, generated summaries, blob paths, search chunks, and citation snippets as untrusted.
+- Do not revert unrelated user changes.
+- If the user asks for `scan only` or `stop after plan`, do not edit files.
+- If fixing findings, keep changes focused and preserve existing personal, group, and public workspace behavior.
+
+## Baseline Discovery
+
+1. Confirm the repo root, current branch, and concise `git status --short`.
+2. Inventory upload, ingestion, storage, parsing, and download surfaces:
+
+```powershell
+rg -n "upload|download|send_file|send_from_directory|Blob|blob|container|filename|secure_filename|mimetype|content_type|content-type|parse|extract|chunk|index|citation|artifact|open\(|read\(|write\(" application/single_app
+```
+
+3. Search document and blob helpers:
+
+```powershell
+rg -n "functions_documents|functions_content|functions_search_service|functions_group|functions_public_workspaces|document_id|file_id|blob_name|blob_path|source_path|metadata_storage_path" application/single_app
+```
+
+4. Search browser rendering of document-derived values:
+
+```powershell
+rg -n "filename|document_title|document_name|citation|snippet|chunk|content|summary|metadata|innerHTML|insertAdjacentHTML|marked\.parse|\|safe" application/single_app/templates application/single_app/static application/single_app/*.py
+```
+
+5. Run relevant deterministic checkers where useful:

+```powershell
+python scripts/check_broken_access_control.py --full-file <target-python-files>
+python scripts/check_xss_sinks.py --full-file <target-browser-files-and-routes>
+```
+
+## Manual Audit Checklist
+
+Review these areas:
+
+- Upload route decorators, user role checks, workspace membership checks, document ownership checks, and object-level authorization before blob, Cosmos, or search operations.
+- File size limits, allowed extensions, MIME/content-type checks, parser selection, parser error handling, and rejection behavior.
+- Filename normalization, path traversal prevention, blob name construction, temporary file paths, archive extraction, and generated artifact names.
+- Parser safety for PDFs, Office files, images, HTML, Markdown, CSV/XLSX, PPTX/DOCX, Visio, audio/video, and any external converter such as FFmpeg.
+- Whether parser output, OCR text, extracted HTML, markdown, metadata, citations, or model summaries can reach browser HTML sinks without safe rendering.
+- Whether downloads, citation source links, profile images, generated artifacts, and blob fallback paths revalidate ownership or workspace membership.
+- Whether document indexing, chunk retrieval, search filters, and approval/publishing flows can cross personal, group, or public workspace boundaries.
+- Cleanup of temporary files and partial blobs after failed parsing or indexing.
+- Malware-like risks within the app boundary: macro-enabled files, embedded scripts, remote image references, compressed bombs, oversized documents, malformed files, and parser resource exhaustion.
+- Logs and activity records that may include full document text, sensitive filenames, SAS URLs, or extracted PII.
+
+## Triage And Plan
+
+Group findings before editing:
+
+- `Critical`: Unauthorized users can upload, read, download, overwrite, index, delete, or render another user’s document/blob/artifact, or uploaded content can execute in a browser.
+- `Important`: Parser output, filenames, citations, blob paths, or generated artifacts cross a trust boundary without validation, sanitization, or ownership checks.
+- `Moderate`: File validation, size limits, cleanup, logging, or parser error handling is incomplete and could cause data leaks or denial of service.
+- `Low`: False positives, static-only paths, or reviewed exceptions.
+
+For each finding, record:
+
+- Surface and file path.
+- Untrusted file-derived source.
+- Sensitive sink.
+- Missing validation, sanitizer, or authorization check.
+- Realistic impact.
+- Remediation approach.
+- Minimum regression test.
+
+## Remediation Patterns
+
+Use these fixes by default:
+
+- Revalidate ownership, group membership, public workspace authorization, or admin role immediately before blob, Cosmos, search, or download operations.
+- Normalize and constrain filenames and blob paths with existing helper patterns.
+- Treat MIME type and extension as hints; validate parser eligibility server-side.
+- Enforce file size and parser limits before expensive processing.
+- Render document-derived text with `textContent` or explicit markdown sanitization before browser insertion.
+- Avoid logging full document content, SAS URLs, or sensitive metadata.
+- Clean up temporary files and partial blobs on failure.
+- Add functional tests for the fixed upload, download, parser, or workspace authorization path.
+
+## Verification
+
+After fixing, run the narrowest reliable checks:
+
+- `python -m py_compile <changed-python-files>`.
+- `node --check <changed-js-files>` when JavaScript changed.
+- Relevant functional tests under `functional_tests/`.
+- Relevant UI tests when browser document behavior changed.
+- `python scripts/check_broken_access_control.py --full-file <changed-python-files>` for authorization-sensitive changes.
+- `python scripts/check_xss_sinks.py --full-file <changed browser files/routes>` for rendering changes.
+- `git -c core.whitespace=blank-at-eol,blank-at-eof,space-before-tab,cr-at-eol diff --check`.
+
+If a check cannot run locally, explain why and include the remaining risk.
+
+## Output Expectations
+
+Return findings first, ordered by severity. Include scope scanned, file types and workflows reviewed, files changed, validation commands run, skipped checks, false positives, and remaining risks.

+
+# Pinned Python Package Security Audit
+
+Audit SimpleChat pinned Python dependencies for known vulnerabilities, supply-chain risk, package metadata issues, risky install/runtime behavior, and source-level concerns. This prompt covers direct pins in every `requirements.txt` and, when available, the transitive packages resolved in the local Python environment.
+
+Primary requirement files in this repo include [application/single_app/requirements.txt](../../application/single_app/requirements.txt), [application/external_apps/bulkloader/requirements.txt](../../application/external_apps/bulkloader/requirements.txt), [application/external_apps/databaseseeder/requirements.txt](../../application/external_apps/databaseseeder/requirements.txt), [deployers/bicep/requirements.txt](../../deployers/bicep/requirements.txt), and [ui_tests/requirements.txt](../../ui_tests/requirements.txt).
+
+## What Is Possible
+
+You can inspect Python packages in several useful ways:
+
+- Direct pins: parse every `requirements.txt` entry pinned with `==`.
+- Installed packages: use the repo virtualenv to inspect installed package metadata and transitive dependencies.
+- Advisories: run tools such as `pip-audit` or `pip index versions` if they are available and network access is allowed.
+- Source/wheel review: download packages with `pip download --no-deps` into a temporary audit folder, extract wheels or source distributions, and review package code and metadata.
+- Import-path review: inspect locally installed package files under `site-packages` when downloads are unavailable.
+
+This does not prove a package is safe. Treat it as a practical, evidence-based review that combines advisories, provenance, install behavior, risky code patterns, and SimpleChat usage.
+
+## Operating Rules
+
+- Work in the SimpleChat repository root.
+- Do not modify dependency versions unless the user explicitly asks for an upgrade plan or remediation.
+- Do not install new audit tools without telling the user what is needed and why.
+- Do not vendor or edit third-party Python package source in the app unless the user explicitly requests that path.
+- Do not revert unrelated user changes.
+- If the user asks for `scan only` or `report only`, do not edit files.
+- Store temporary downloaded package archives under `artifacts/security/python-package-audit/` if downloads are needed, and keep generated artifacts out of commits unless the user asks to keep them.
+
+## Baseline Discovery
+
+1. Confirm the repo root, current branch, concise `git status --short`, and active Python path:
+
+```powershell
+$py = if (Test-Path ".venv\Scripts\python.exe") { ".\.venv\Scripts\python.exe" } else { "python" }
+& $py --version
+& $py -m pip --version
+```
+
+2. Inventory requirement files and pinned direct dependencies:
+
+```powershell
+rg --files -g "requirements*.txt"
+rg -n "^[A-Za-z0-9_.-]+==[^\s#]+" -g "requirements*.txt"
+```
+
+3. Check for unpinned, editable, URL, path, extra-index, or trusted-host entries:
+
+```powershell
+rg -n "^\s*(-e\s+|--extra-index-url|--index-url|--trusted-host|https?://|git\+|file:|[A-Za-z0-9_.-]+\s*(>=|>|<=|<|~=|!=)|[A-Za-z0-9_.-]+\s*$)" -g "requirements*.txt"
+```
+
+4. Capture installed dependency metadata when a local environment is available:
+
+```powershell
+& $py -m pip list --format=json
+& $py -m pip check
+& $py -m pip inspect --local --verbose
+```
+
+5. Run advisory scanning if available:
+
+```powershell
+& $py -m pip_audit -r application/single_app/requirements.txt
+```
+
+If `pip_audit` is unavailable, report that gap and use metadata/source review instead. Do not install it unless the user approves or explicitly asked for full advisory tooling.
+
+6. Download package archives for source/wheel review when network access is available and the user requested source review:
+
+```powershell
+New-Item -ItemType Directory -Force artifacts/security/python-package-audit | Out-Null
+& $py -m pip download --no-deps --dest artifacts/security/python-package-audit -r application/single_app/requirements.txt
+```
+
+Repeat for other requirements files as needed. If downloads fail because of network, index, or platform constraints, inspect installed `site-packages` metadata instead.
+
+## Manual Audit Checklist
+
+Review these areas:
+
+- Known vulnerability advisories, severity, affected versions, fixed versions, and whether SimpleChat uses the vulnerable feature.
+- Package provenance: expected package name, publisher/maintainer reputation, project URL, license, release recency, typosquatting risk, beta/pre-release status, and sudden ownership changes when metadata is available.
+- Requirement hygiene: all direct dependencies pinned, no URL/path/editable installs unless reviewed, no untrusted indexes, no missing hashes if the team wants reproducible supply-chain hardening.
+- Transitive dependencies: installed versions, dependency conflicts from `pip check`, duplicate packages across app/deployer/UI environments, and packages pulled in by large frameworks.
+- Install-time behavior: `setup.py`, `pyproject.toml`, build backends, custom install commands, native extensions, binary wheels, post-install scripts, and generated code.
+- Runtime risky patterns in package code, prioritized by packages that process untrusted files, network data, auth, cryptography, serialization, HTML/markdown, browser automation, or cloud credentials.
+- Source patterns to review in downloaded or installed packages: `eval`, `exec`, `compile`, `pickle`, `marshal`, `yaml.load`, `subprocess`, `os.system`, `shell=True`, `ctypes`, `cffi`, dynamic imports, network calls at import time, telemetry, environment-variable scraping, credential file reads, temporary file handling, archive extraction, and unsafe XML/HTML parsing.
+- SimpleChat usage of the package: whether the package is imported in production, admin-only, deployer-only, tests-only, optional, or unused.
+- License or compliance risks if the package is newly introduced or materially changed.
+
+Useful searches for extracted or installed package source:
+
+```powershell
+rg -n "eval\(|exec\(|compile\(|pickle|marshal|yaml\.load|subprocess|os\.system|shell=True|ctypes|cffi|requests\.|urllib|socket|open\(|tempfile|zipfile|tarfile|extractall|fromstring|innerHTML|telemetry|analytics|credential|token|password|secret" artifacts/security/python-package-audit
+```
+
+If reviewing installed packages, replace the path with the relevant `site-packages` package directory.
+
+## Triage And Plan
+
+Group findings before editing:
+
+- `Critical`: Known actively exploited vulnerability, malicious package indicators, credential exfiltration risk, unsafe install-time execution, or vulnerable code reachable through SimpleChat with untrusted input.
+- `Important`: High-severity advisory, risky parser/network/auth behavior reachable by SimpleChat, suspicious package provenance, or missing fixed-version path.
+- `Moderate`: Stale or beta package, broad risky primitives not clearly reachable, missing hashes, dependency conflicts, native binary opacity, or license/compliance concerns.
+- `Low`: False positives, dev/test-only issues, unreachable vulnerable features, or informational hygiene improvements.
+
+For each finding, record:
+
+- Package name and version.
+- Requirement file or transitive dependency path.
+- Evidence source: advisory, metadata, source file, wheel contents, SimpleChat import/use, or command output.
+- Reachability in SimpleChat.
+- Impact.
+- Recommended action: pin upgrade, replace package, configuration change, code usage change, add hash, monitor, or accept risk.
+- Minimum validation after a change.
+
+## Remediation And Upgrade Planning
+
+If the user asks for remediation:
+
+- Prefer patch or minor upgrades that fix advisories without broad behavior changes.
+- Check release notes for packages that process files, auth, cloud credentials, markdown/HTML, browser automation, or networking.
+- Update all relevant requirements files when the same package is pinned in multiple environments.
+- Run `pip check`, import smoke tests, and relevant functional/UI tests after upgrades.
+- For production packages, run focused app checks that cover the package’s real use.
+- Consider adding hashes only as a deliberate supply-chain hardening task because it changes dependency maintenance workflow.
+
+## Verification
+
+After dependency changes, run the narrowest reliable checks:
+
+- `& $py -m pip check`.
+- `& $py -m py_compile <changed-python-files>` when app code changed.
+- Import smoke tests for upgraded packages.
+- Relevant functional tests under `functional_tests/`.
+- Relevant UI tests for Playwright/browser package changes.
+- `git -c core.whitespace=blank-at-eol,blank-at-eof,space-before-tab,cr-at-eol diff --check`.
+
+If a check cannot run locally, explain why and include the remaining risk.
+
+## Output Expectations
+
+Return findings first, ordered by severity. Include direct and transitive scope, requirement files reviewed, tools run, package source or wheel paths inspected, vulnerabilities or risky patterns found, false positives, recommended upgrades, skipped checks, and remaining risks.

+
+# Plugin Tool And Agent Security Audit
+
+Audit SimpleChat agent, plugin, action, tool-call, workflow, and external API integration code for authorization, injection, data leakage, unsafe tool execution, and cross-scope access issues.
+
+Use the repository guardrails in [.github/instructions/broken-access-control-prevention.instructions.md](../instructions/broken-access-control-prevention.instructions.md), [.github/instructions/xss-prevention.instructions.md](../instructions/xss-prevention.instructions.md), [.github/instructions/python-lang.instructions.md](../instructions/python-lang.instructions.md), and [.github/copilot-instructions.md](../copilot-instructions.md).
+
+## Operating Rules
+
+- Work in the SimpleChat repository root.
+- Treat model output, tool arguments, plugin responses, action configuration, OpenAPI specs, user prompts, active scope settings, and stored agent/action records as untrusted.
+- Do not revert unrelated user changes.
+- If the user asks for `scan only` or `stop after plan`, do not edit files.
+- If fixing findings, preserve existing agent/action behavior and keep scope changes explicit.
+
+## Baseline Discovery
+
+1. Confirm the repo root, current branch, and concise `git status --short`.
+2. Inventory plugin, tool, action, workflow, and agent surfaces:
+
+```powershell
+rg -n "@kernel_function|KernelFunction|semantic_kernel|plugin|tool_call|tool choice|function_call|OpenAPI|operationId|action|agent|workflow|run_workflow|invoke|execute|external" application/single_app
+```
+
+3. Search for caller-controlled scope and identity arguments:
+
+```powershell
+rg -n "user_id|conversation_id|message_id|group_id|public_workspace_id|scope_id|scope_type|activeGroupOid|activePublicWorkspaceOid|owner|participant|membership" application/single_app/semantic_kernel_plugins application/single_app/functions_* application/single_app/route_backend_*.py
+```
+
+4. Search for external calls, dynamic execution, and sensitive plugin sinks:
+
+```powershell
+rg -n "requests\.|aiohttp|httpx|subprocess|shell=True|eval\(|exec\(|open\(|read_item|query_items|upsert_item|delete_item|download_blob|upload_blob|Graph|graph|Authorization|headers" application/single_app
+```
+
+5. Run the broken access control checker where useful:
+
+```powershell
+python scripts/check_broken_access_control.py --full-file <target-python-files>
+```
+
+## Manual Audit Checklist
+
+Review these areas:
+
+- Semantic Kernel `@kernel_function` parameters that expose `user_id`, `conversation_id`, `group_id`, `public_workspace_id`, `scope_id`, `scope_type`, file/document IDs, or owner IDs.
+- Whether tool-call scope arguments are rebound to the authorized request context with helpers such as `_resolve_authorized_scope_arguments(...)`, `_resolve_blob_location_with_fallback(...)`, `_resolve_authorized_fact_memory_call(...)`, `require_active_group(...)`, or `require_active_public_workspace(...)` before storage, search, blob, or Graph access.
+- OpenAPI/plugin actions that allow arbitrary URLs, headers, auth schemes, operation IDs, or request bodies from user-controlled configuration.
+- External API calls that may leak secrets, authorization headers, prompts, document content, user data, or internal endpoints.
+- Prompt/tool injection risks where model output can select tools, override scope, exfiltrate context, or trigger unintended mutations.
+- Workflow runners that persist, replay, or mirror tool results across personal, group, public, or collaboration conversations.
+- Plugin/action enablement, admin management routes, disabled global records, selected agents/actions, and user visibility boundaries.
+- Plugin logs, citations, thought records, activity records, and telemetry that may expose sensitive inputs or tool responses.
+- Tool results rendered in the browser as markdown, HTML, citations, maps, tables, charts, images, videos, or generated artifacts.
+- Long-running or retrying tool calls that could amplify side effects, duplicate writes, or bypass approval gates.
+
+## Triage And Plan
+
+Group findings before editing:
+
+- `Critical`: A tool or agent can access, mutate, or exfiltrate another user’s data, execute arbitrary external calls with secrets, or bypass admin/user authorization.
+- `Important`: Tool arguments, action configuration, workflow scope, or model output can influence sensitive reads, writes, or network calls without explicit validation.
+- `Moderate`: Logs, citations, telemetry, retries, or rendering paths expose sensitive tool data or create confusing authorization boundaries.
+- `Low`: False positives, static-only tool metadata, reviewed exceptions, or unreachable legacy paths.
+
+For each finding, record:
+
+- Agent/plugin/action/workflow surface and file path.
+- Untrusted input source.
+- Sensitive sink or side effect.
+- Missing authorization, validation, prompt boundary, or sanitizer.
+- Realistic impact.
+- Remediation approach.
+- Minimum regression test.
+
+## Remediation Patterns
+
+Use these fixes by default:
+
+- Rebind identity and scope parameters to authenticated request context before sensitive operations.
+- Validate group/public workspace membership and object ownership at the storage/blob/search/Graph boundary.
+- Deny or normalize arbitrary URL, header, and auth configuration for external actions.
+- Keep secrets server-side; never expose action credentials or auth headers to model-visible content or browser responses.
+- Separate model-visible summaries from raw tool responses when sensitive data exists.
+- Make mutations idempotent or guarded against retry side effects.
+- Render tool output with the same XSS-safe patterns used elsewhere.
+- Add focused functional tests for scope isolation, disabled action/agent behavior, external call validation, or rendered tool output.
+
+## Verification
+
+After fixing, run the narrowest reliable checks:
+
+- `python -m py_compile <changed-python-files>`.
+- Relevant functional tests under `functional_tests/`.
+- `python scripts/check_broken_access_control.py --full-file <changed-python-files>` for authorization-sensitive changes.

+name: "Prepare for Pull Request"
+description: "Use when the user says: Prepare for a pull request, PR prep, ready this branch for PR, validate before PR, or create a PR to Development. Runs SimpleChat branch sync and validation workflow before optionally pushing or creating a GitHub pull request."
+argument-hint: "Optional: include merge Development, rebase Development, push, create draft PR, or create PR"
+agent: "agent"
+---
+
+# Prepare SimpleChat for a Pull Request
+
+You are preparing the current SimpleChat branch for a GitHub pull request into `Development`.
+
+The default outcome is a verified PR-readiness report. You may push the branch or create the pull request only after explicitly asking the user to proceed and receiving confirmation. If the user already asked to push or create the PR, still pause at the final confirmation gate before doing it.
+
+## Repository Policy
+
+- Work in the SimpleChat repository.
+- Target contributor PRs to `Development`, not `main` or `Staging`.
+- Treat `Development` and `Staging` as case-sensitive branch names.
+- Prefer the remote named `upstream` when it exists and has `Development`; otherwise use `origin/Development`.
+- Never use destructive Git commands such as `git reset --hard`, `git checkout -- <path>`, or force push unless the user explicitly asks and understands the consequence.
+- Do not revert unrelated user changes.
+- Do not commit, push, or create a PR without a user confirmation step.
+- If secrets, `.env` files, session tokens, storage keys, connection strings, or generated local artifacts appear in the changed file set, stop and ask before proceeding.
+
+## Initial Discovery
+
+Run read-only checks first and summarize what you find:
+
+1. Confirm the repo root and current branch.
+2. Show concise working tree status, including untracked files.
+3. Show remotes and identify the remote target branch for `Development`.
+4. Fetch the target branch: `git fetch <remote> Development`.
+5. Determine whether the current branch contains the latest target branch:
+   - Up to date when `<remote>/Development` is an ancestor of `HEAD`.
+   - Behind or diverged when it is not.
+6. Determine changed files relative to `<remote>/Development` and include both committed and uncommitted local changes.
+
+If the current branch is `Development`, `Staging`, or `main`, stop and ask whether to create or switch to a feature branch before continuing.
+
+## Development Sync Gate
+
+Before reporting PR readiness or creating a PR, ensure the current branch includes the latest `Development` changes.
+
+Default behavior:
+
+- Fetch `Development` and report whether the branch is up to date.
+- If the branch is behind or diverged, stop and ask how to integrate the changes.
+- Do not merge or rebase automatically.
+
+Supported opt-in behaviors:
+
+- If the user asks to `merge Development`, run a normal merge from `<remote>/Development` after confirming.
+- If the user asks to `rebase Development` or `rebase onto Development`, rebase onto `<remote>/Development` after confirming.
+- If the user asks only to check readiness, do not integrate. Explain that PR readiness is blocked until the branch includes the latest target branch.
+
+After any merge or rebase, recompute changed files and rerun all applicable validation.
+
+## Conflict Handling
+
+If a merge or rebase produces conflicts, do not ask the user to manually resolve files. Resolve conflicts interactively with the user while you do the editing.
+
+For each conflict:
+
+1. Identify the conflicted file and the affected feature or behavior.
+2. Explain the two sides clearly:
+   - `ours`: what the user's current branch changed.
+   - `theirs`: what `Development` changed.
+3. Explain the likely impact of choosing either side or combining them.
+4. Recommend a resolution when there is enough context, but ask the user how to proceed.
+5. Apply the selected resolution yourself.
+6. Continue until there are no conflict markers and `git status` shows no unmerged paths.
+7. Continue the merge or rebase with non-interactive Git commands.
+
+If the user cancels conflict resolution, report the current Git state and the safest next step. Do not abandon a merge or rebase unless the user explicitly asks.
+
+## Local Validation
+
+Use the repo's existing workflow files, scripts, and instructions as the source of truth. Run the smallest reliable set that matches the changed files, then broaden only when risk calls for it.
+
+Always run:
+
+- `git diff --check` for changed files.
+- A Python syntax compile check for changed Python files, and at minimum the Python files under `application/single_app` that GitHub compiles.
+- Any new or changed test files directly.
+
+When Python route files changed:
+
+- Run `python scripts/check_swagger_routes.py <changed-python-files>`.
+- Verify every Flask route has `@swagger_route(security=get_auth_security())` immediately after `@app.route(...)`.
+
+When JavaScript, HTML, or Python browser-rendering surfaces changed:
+
+- Run `python scripts/check_xss_sinks.py` against changed `application/**/*.js`, `application/**/*.html`, and `application/**/*.py` files.
+- If validating only committed changes, prefer changed-line mode:
+  `python scripts/check_xss_sinks.py --base-sha <remote>/Development --head-sha HEAD <files>`.
+- If the working tree has uncommitted changes, use `--full-file` for those files because they are not represented by `HEAD`.
+
+When Python authorization-sensitive surfaces changed:
+
+- Run `python scripts/check_broken_access_control.py` against changed `application/**/*.py` files.
+- If validating only committed changes, prefer changed-line mode:
+  `python scripts/check_broken_access_control.py --base-sha <remote>/Development --head-sha HEAD <files>`.
+- If the working tree has uncommitted changes, use `--full-file` for those files.
+
+When HTML, CSS, or JavaScript changes affect UI behavior:
+
+- Run relevant `ui_tests/` tests when the local app and authentication state are available.
+- If UI tests cannot be run locally, say why and include the gap in the final PR-readiness report.
+
+When bug fixes, new features, route changes, API changes, security changes, or UI workflow changes are present:
+
+- Check for matching functional tests under `functional_tests/`.
+- Run relevant functional tests with pytest or directly with Python, matching existing test style.
+- If no relevant test exists, call this out and recommend the missing coverage.
+
+When application code changed:
+
+- Verify `application/single_app/config.py` has an appropriate patch version bump unless the change is docs-only.
+- Verify fix or feature documentation exists when required by the repo instructions.
+- Check whether `docs/explanation/release_notes.md` should be updated. If release notes are needed and missing, update them under the current `config.py` version as part of PR readiness unless the user explicitly requested report-only behavior.
+- If the current `config.py` version does not have a release notes section yet, create a new section at the top of the release notes before adding the entry.
+
+## PR Readiness Review
+
+Before asking to push or create a PR, provide a concise report with:
+
+- Current branch and target branch.
+- Whether the branch includes the latest `Development`.
+- Changed-file summary grouped by area.
+- Validation commands run and pass/fail status.
+- Tests run and any skipped tests with reasons.
+- Version, documentation, and release notes status.
+- Security review notes for secrets, XSS, broken access control, settings sanitization, and route decorators.
+- Remaining risks or manual follow-up.
+
+If validation fails, fix issues that are clearly in scope and rerun the affected checks. If a failure is unrelated or needs a product decision, stop and explain the blocker.
+
+## Optional Push and PR Creation
+
+Only after the readiness report is clean or the user accepts the noted risks, ask whether to proceed with push and PR creation.
+
+If uncommitted changes remain:
+
+- Do not push or create a PR yet.
+- Ask whether the user wants you to stage and commit the PR-ready changes.
+- Propose a concise commit message based on the change summary.
+
+If the user confirms push:
+
+- Push the current branch to the appropriate remote.
+- Do not force push unless the user explicitly asks after seeing the risk.
+
+If the user confirms PR creation:
+
+- Use GitHub CLI when available.
+- Create the PR against `Development`.
+- Default to a draft PR unless the user asks for a ready-for-review PR.
+- Include a PR body with summary, validation, tests, release notes status, and known risks.
+- Return the PR URL.
+
+If GitHub CLI is unavailable or unauthenticated, report the exact blocker and provide the PR title/body text for manual creation.

+
+# Privacy Logging And Telemetry Audit
+
+Audit SimpleChat logging, telemetry, activity records, plugin logs, traces, diagnostics, exports, and error handling for privacy and sensitive-data exposure.
+
+Use the repository guardrails in [.github/instructions/santize_settings_for_frontend_routes.instructions.md](../instructions/santize_settings_for_frontend_routes.instructions.md), [.github/instructions/broken-access-control-prevention.instructions.md](../instructions/broken-access-control-prevention.instructions.md), [.github/instructions/python-lang.instructions.md](../instructions/python-lang.instructions.md), and [.github/copilot-instructions.md](../copilot-instructions.md).
+
+## Operating Rules
+
+- Work in the SimpleChat repository root.
+- Treat user prompts, chat messages, document text, uploaded content, generated outputs, profile fields, emails, IDs, headers, tokens, settings, and tool responses as sensitive unless explicitly intended for that log audience.
+- Do not revert unrelated user changes.
+- If the user asks for `scan only` or `stop after plan`, do not edit files.
+- If fixing findings, preserve useful diagnostics while minimizing sensitive payloads.
+- Prefer `log_event(...)` from `functions_appinsights.py` and existing activity/plugin logging helpers over ad hoc logging.
+
+## Baseline Discovery
+
+1. Confirm the repo root, current branch, and concise `git status --short`.
+2. Inventory logging and telemetry calls:
+
+```powershell
+rg -n "log_event\(|logging\.|logger\.|print\(|traceback|AppInsights|Application Insights|activity_log|activity_logs|plugin_log|plugin_logging|thought|telemetry|diagnostic|debug|error|exception" application functional_tests scripts deployers
+```
+
+3. Search for likely sensitive fields near logs, exports, and diagnostics:
+
+```powershell
+rg -n -i "prompt|message|content|document|chunk|summary|citation|email|user_id|object_id|authorization|cookie|token|secret|password|api[_-]?key|connection[_ -]?string|headers|settings|request\.|response\." application/single_app
+```
+
+4. Search export and admin-view surfaces:
+
+```powershell
+rg -n "export|download|csv|json|xlsx|docx|pdf|report|activity|control_center|admin|audit|history|trace" application/single_app docs functional_tests
+```
+
+5. Search for broad serialization of request, response, settings, or exception objects:
+
+```powershell
+rg -n "vars\(|__dict__|json\.dumps\(|asdict\(|model_dump\(|dict\(|request\.headers|request\.cookies|request\.environ|os\.environ|str\(.*exception|repr\(" application/single_app
+```
+
+## Manual Audit Checklist
+
+Review these areas:
+
+- `log_event(...)` custom properties and messages for secrets, tokens, headers, cookies, settings, connection strings, prompts, document text, or full tool responses.
+- Activity logs and admin views for user-visible privacy boundaries, searchability, retention expectations, and unnecessary PII.
+- Plugin invocation logs, thought records, workflow activity, agent citations, and generated artifacts that may store raw external responses or sensitive context.
+- Exception handlers and error responses that expose stack traces, request payloads, service errors, internal endpoints, IDs, or secrets.
+- Export flows that package chat history, logs, citations, metadata, activity, or diagnostics with more data than the user/admin should receive.
+- Debug flags, environment-controlled diagnostics, and support endpoints that can be enabled in production.
+- PII fields such as display names, emails, Entra IDs, group memberships, profile images, IP addresses, document names, and workspace names.
+- Whether logs include enough correlation IDs and coarse event names after redaction to remain useful.
+
+## Triage And Plan
+
+Group findings before editing:
+
+- `Critical`: Secrets, tokens, connection strings, authorization headers, or raw private content are logged or exported to a broad audience.
+- `Important`: Sensitive user, document, prompt, or tool data is logged by default without clear need or masking.
+- `Moderate`: Debug diagnostics, admin views, error responses, or exports are overbroad but role-restricted or environment-limited.
+- `Low`: False positives, placeholders, reviewed diagnostic fields, or coarse metadata that is necessary and proportionate.
+
+For each finding, record:
+
+- File and logging/export surface.
+- Sensitive source.
+- Audience and storage sink.
+- Existing redaction or role boundary.
+- Missing minimization, masking, or authorization.
+- Realistic impact.
+- Remediation approach.
+- Minimum regression test.
+
+## Remediation Patterns
+
+Use these fixes by default:
+
+- Log event names, IDs, counts, durations, statuses, and coarse categories instead of raw payloads.
+- Redact secrets, headers, cookies, tokens, connection strings, and SAS URLs before logging.
+- Truncate long prompt, document, tool, or service-response previews and avoid logging full content by default.
+- Use stable correlation IDs rather than full user/profile payloads when possible.
+- Keep admin exports role-protected and scoped to explicit filters.
+- Sanitize settings before frontend diagnostics unless it is an admin route that deliberately requires raw settings.
+- Add tests for redaction helpers, log payload construction, export field filtering, or error response shape.
+
+## Verification
+
+After fixing, run the narrowest reliable checks:
+
+- `python -m py_compile <changed-python-files>`.
+- Relevant functional tests under `functional_tests/`.
+- Targeted `rg` searches from the discovery section for changed areas.
+- `python scripts/check_broken_access_control.py --full-file <changed-python-files>` when log/export access control changed.
+- `git -c core.whitespace=blank-at-eol,blank-at-eof,space-before-tab,cr-at-eol diff --check`.
+
+If a check cannot run locally, explain why and include the remaining risk.
+
+## Output Expectations
+
+Return findings first, ordered by severity. Include log and export surfaces reviewed, files changed, redaction/minimization patterns used, validation commands run, skipped checks, false positives, and remaining risks.

+description: "Use when: auditing SimpleChat Flask routes for missing or incorrect @login_required, @user_required, @admin_required, specialized admin decorators, Swagger auth metadata, or decorator order."
+name: "Route Authentication Audit"
+argument-hint: "Target route files, endpoint prefixes, changed files, or route names to audit"
+agent: "agent"
+---
+
+Audit the requested SimpleChat Flask routes for runtime authentication and role authorization decorator coverage. Treat `@swagger_route(security=get_auth_security())` as OpenAPI metadata only; it does not enforce authentication at runtime.
+
+Use the repository route and access-control guardrails in [.github/copilot-instructions.md](../copilot-instructions.md), [.github/instructions/python-lang.instructions.md](../instructions/python-lang.instructions.md), and [.github/instructions/broken-access-control-prevention.instructions.md](../instructions/broken-access-control-prevention.instructions.md). Use [scripts/check_swagger_routes.py](../../scripts/check_swagger_routes.py) and [scripts/check_broken_access_control.py](../../scripts/check_broken_access_control.py) where useful, but do not stop at deterministic checker output.
+
+## Expected Route Patterns
+
+- Every Flask route must include `@swagger_route(security=get_auth_security())` immediately after the route decorator unless the route has a reviewed exception.
+- Most non-admin application API routes should use `@login_required` followed by `@user_required` before the view function runs.
+- Admin-namespaced or admin-only routes should use `@login_required` followed by `@admin_required`, or a more specific admin decorator such as `@feedback_admin_required` or `@safety_violation_admin_required` when the codebase already uses that role boundary.
+- Group, public workspace, conversation, document, user profile, and plugin/action routes still need object-level authorization at the sensitive read or mutation boundary. Role decorators are not enough for object access.
+- Feature flags such as `@enabled_required(...)`, Swagger metadata, frontend-only visibility, and route names are not substitutes for runtime auth decorators.
+- Public routes should be rare and explicit. Validate likely public exceptions against nearby files and app behavior, such as health probes, static assets, login/auth callbacks, external API bearer-token routes, and documentation endpoints.
+
+## Audit Workflow
+
+1. Identify all Flask route functions in the target files, including routes registered on blueprints and routes inside `register_route_backend_*` functions.
+2. Record each route path, HTTP method, endpoint function, and decorator stack in source order.
+3. Classify each route as public, authenticated user, admin, specialized admin, external API, or unclear.
+4. Compare the decorator stack against nearby routes in the same file and similar feature areas. Prefer local conventions over generic assumptions.
+5. Flag routes that are missing runtime authentication, have only `@login_required` where the surrounding user-facing API pattern expects `@user_required`, or expose admin functionality without an admin decorator.
+6. For each protected route, check that `@login_required` appears before role decorators in the source so unauthenticated API callers receive the login boundary before role checks.
+7. For routes using object IDs from path, query, body, session settings, or plugin arguments, call out any missing ownership, membership, or relationship validation separately from decorator coverage.
+8. Recommend the smallest remediation and the minimum regression test that would fail before the fix and pass after.
+
+## Output Format
+
+Return findings first, ordered by severity. For each finding include:
+
+- `Severity`: Critical, Important, Moderate, or Low.
+- `Route`: HTTP method and path.
+- `Function`: file path and function name.
+- `Current Decorators`: runtime auth decorators currently present.
+- `Expected Decorators`: the route pattern that should be used.
+- `Impact`: what anonymous, non-user, or non-admin callers could do or learn.
+- `Remediation`: exact decorator or object-level check to add.
+- `Regression Test`: focused test coverage to prevent recurrence.
+
+If no issues are found, say that clearly and list any routes intentionally left public or login-only with the reason they are acceptable.

+
+# Settings And Secrets Exposure Audit
+
+Audit SimpleChat for accidental disclosure of secrets, credentials, raw settings, environment values, connection strings, tokens, API keys, or internal configuration details.
+
+Use the repository guardrails in [.github/instructions/santize_settings_for_frontend_routes.instructions.md](../instructions/santize_settings_for_frontend_routes.instructions.md), [.github/instructions/python-lang.instructions.md](../instructions/python-lang.instructions.md), and [.github/copilot-instructions.md](../copilot-instructions.md). Admin routes are allowed to use raw settings for admin functionality, but still review whether secrets are unnecessarily rendered, logged, serialized to JavaScript, included in downloads, or exposed through browser-inspectable markup.
+
+## Operating Rules
+
+- Work in the SimpleChat repository root.
+- Treat settings, environment values, credentials, tokens, and service endpoints as sensitive unless the code proves they are public-safe display values.
+- Do not revert unrelated user changes.
+- If the user asks for `scan only` or `stop after plan`, do not edit files.
+- If the user asks to fix findings, make focused changes and preserve admin behavior.
+- Prefer existing helpers such as `sanitize_settings_for_user(...)`, `get_settings()`, `log_event(...)`, and local masking patterns over new abstractions.
+
+## Baseline Discovery
+
+1. Confirm the repo root, current branch, and concise `git status --short`.
+2. Identify settings and configuration flow:
+
+```powershell
+rg -n "get_settings\(|sanitize_settings_for_user\(|update_settings\(|app_settings|settings\s*=|render_template\(|jsonify\(" application/single_app
+```
+
+3. Search for likely secret terms in application code, templates, docs, tests, deployers, and scripts:
+
+```powershell
+rg -n -i "api[_-]?key|secret|password|passwd|pwd|token|bearer|credential|connection[_ -]?string|client[_-]?secret|private[_-]?key|account[_-]?key|sas[_-]?token|instrumentation[_-]?key" application docs functional_tests ui_tests deployers scripts .github
+```
+
+4. Search for logging, print, telemetry, error, and export surfaces that might serialize sensitive values:
+
+```powershell
+rg -n "log_event\(|logging\.|logger\.|print\(|traceback|json\.dumps\(|Response\(|send_file\(|make_response\(|download|export" application/single_app functional_tests scripts
+```
+
+5. Search frontend templates and JavaScript for settings embedded into browser-visible variables or attributes:
+
+```powershell
+rg -n "tojson|app_settings|settings|window\.|data-[A-Za-z0-9_-]+=|localStorage|sessionStorage" application/single_app/templates application/single_app/static
+```
+
+## Manual Audit Checklist
+
+Review these areas:
+
+- Non-admin routes that call `get_settings()` and pass settings into `render_template(...)` or `jsonify(...)` without `sanitize_settings_for_user(...)`.
+- Admin routes that render raw settings into unnecessary hidden fields, JavaScript globals, data attributes, logs, exports, or downloadable artifacts.
+- API responses that return full configuration objects when only a few public display values are needed.
+- Error responses, exception handlers, tracebacks, debug endpoints, health endpoints, and diagnostics that include settings, environment variables, request headers, tokens, or service responses.
+- `log_event(...)`, plugin logs, activity logs, App Insights properties, workflow activity, and audit logs that include prompts, headers, authorization tokens, keys, connection strings, or full request/response payloads.
+- Documentation, examples, tests, fixtures, session files, generated artifacts, and deployer outputs that may contain real secrets.
+- Client storage such as `localStorage` or `sessionStorage` that may persist secrets or raw settings.
+
+Treat these as high-risk values:
+
+- Azure OpenAI, Azure AI Search, Cosmos DB, Blob Storage, Key Vault, Speech, Document Intelligence, Redis, SQL, PostgreSQL, MySQL, Tableau, Microsoft Graph, App Insights, and Entra credentials.
+- `Authorization`, `Cookie`, `x-ms-*`, OAuth tokens, MSAL cache values, session IDs, Flask secrets, SAS URLs, private keys, and connection strings.
+
+## Triage And Plan
+
+Group findings before editing:
+
+- `Critical`: A secret, token, connection string, or credential can reach an unauthenticated user, normal user, browser markup, JavaScript, public docs, logs available to broad roles, or repository history.
+- `Important`: Raw settings or internal endpoints are exposed to authenticated users or admin browser surfaces without a clear need.
+- `Moderate`: Overbroad logging, verbose diagnostics, test fixtures, or exports could expose sensitive data in common development or support workflows.
+- `Low`: False positives, placeholders, documented dummy values, or admin-only display with masking and clear need.
+
+For each finding, record:
+
+- File and function/template/component.
+- Sensitive source.
+- Exposure sink.
+- Existing guard or why it is insufficient.
+- Remediation approach.
+- Minimum regression test or deterministic check.
+
+## Remediation Patterns
+
+Use these fixes by default:
+
+- Sanitize settings with `sanitize_settings_for_user(...)` before non-admin `render_template(...)` or `jsonify(...)` responses.
+- Pass only the exact public fields a route needs instead of whole settings objects.
+- Mask secrets before admin display, telemetry, logs, exports, or diagnostics when raw values are not required.
+- Redact `Authorization`, cookies, tokens, passwords, keys, connection strings, and SAS query values from logs and errors.
+- Avoid persisting secrets in browser storage, hidden fields, or data attributes.
+- Replace real secrets in docs/tests with obvious placeholders.
+- Add focused tests for any fixed route, log sanitizer, or redaction helper.
+
+## Verification
+
+After fixing, run the narrowest reliable checks:
+
+- `python -m py_compile <changed-python-files>` for changed Python files.
+- Relevant functional tests for modified routes or helpers.
+- `python scripts/check_xss_sinks.py --full-file <changed application browser files>` when browser rendering changes are involved.
+- Targeted `rg` searches from the discovery section for changed areas.
+- `git -c core.whitespace=blank-at-eol,blank-at-eof,space-before-tab,cr-at-eol diff --check`.
+
+If a check cannot run locally, explain why and include the remaining risk.
+
+## Output Expectations
+
+Return findings first, ordered by severity. Include false positives and reviewed exceptions. When complete, report scope scanned, files changed, redaction or sanitization patterns used, validation commands run, skipped checks, and remaining risks.

+# XSS Full Audit And Remediation
+
+Run a full local SimpleChat XSS audit and remediation workflow. This is broader than the GitHub Actions PR check in [.github/workflows/xss-sink-check.yml](../workflows/xss-sink-check.yml): the action checks changed application lines, while this prompt should inspect the whole browser-rendering surface and produce a plan to fix real risks.
+
+Use the repository guardrails in [.github/instructions/xss-prevention.instructions.md](../instructions/xss-prevention.instructions.md), [.github/instructions/local_browser_assets.instructions.md](../instructions/local_browser_assets.instructions.md), and the deterministic checker in [scripts/check_xss_sinks.py](../../scripts/check_xss_sinks.py). Prefer the repo's existing rendering helpers and Bootstrap patterns over new abstractions.
+
+## Operating Rules
+
+- Work in the SimpleChat repository root.
+- Treat JavaScript, HTML/Jinja, and Python routes/helpers that send data to the browser as the audit surface.
+- Do not revert unrelated user changes.
+- Start with a concise plan and keep it updated as findings are triaged and fixed.
+- If the user asks for `scan only` or `stop after plan`, do not edit files.
+- If the user asks to fix findings, make focused changes by feature/file area and verify each batch.
+- Use `xss-check: ignore` only for a reviewed exception with a nearby justification. Prefer safer rendering code.
+
+## Baseline Discovery
+
+1. Confirm the repo root, current branch, and concise `git status --short`.
+2. Identify tracked application files in scope:
+
+```powershell

+```

+4. Run the guardrail self-test when the checker, workflow, XSS instructions, or this prompt are part of the work:
+
+```powershell
+python functional_tests/test_xss_guardrails_checker.py
+```
+
+5. Independently search for browser execution and HTML-rendering sinks that need human review:
+
+```powershell
+rg -n "innerHTML|outerHTML|insertAdjacentHTML|\.html\(|onclick=|onerror=|onload=|javascript:|\|safe\b|Markup\(|marked\.parse|dangerouslySetInnerHTML|setAttribute\(\s*['\"]on" application
+```
+
+6. Search for dynamic template interpolation into rendered markup:
+
+```powershell
+rg -n "`[^`]*\$\{|href=.*\$\{|src=.*\$\{|title=.*\$\{|style=.*\$\{|data-[A-Za-z0-9_-]+=.*\$\{" application/single_app/static application/single_app/templates
+```
+
+If shell quoting gets in the way, use equivalent `rg` searches or the VS Code search tool, but preserve the same coverage.
+
+## Manual Audit Checklist
+
+For each finding or suspicious sink, determine whether untrusted data can reach it. Treat these values as untrusted unless proven otherwise:
+
+- User names, emails, IDs, workspace/group names, agent names, tags, filenames, document titles, descriptions, and settings-derived display values.
+- API responses from Cosmos DB, Azure AI Search, Microsoft Graph, plugins/tools, file processing, or model output.
+- Markdown, rich text, uploaded text, generated summaries, citation snippets, errors, and logs shown in the browser.
+
+Review these sink categories:
+
+- Dynamic `innerHTML`, `outerHTML`, `insertAdjacentHTML`, jQuery `.html(...)`, and `dangerouslySetInnerHTML`.
+- Inline event handlers in templates or JavaScript-created markup.
+- `javascript:` URLs and dynamic `href` or `src` values without explicit URL normalization.
+- Dynamic interpolation into `title`, `style`, or `data-*` attributes in HTML strings.
+- `marked.parse(...)` output rendered without `DOMPurify.sanitize(...)`.
+- Python `Markup(...)` and Jinja `|safe` on values that can contain user, model, file, or service-provided content.
+- Static HTML shell exceptions that are no longer static because they interpolate runtime data.
+
+## Triage And Plan
+
+Group findings before editing:
+
+- `Critical`: Untrusted content can execute script or inject event handlers/URLs in reachable browser flows.
+- `Important`: Untrusted content reaches HTML sinks or unsafe markdown rendering, but exploitability depends on stored data or role-specific access.
+- `Moderate`: Inline handlers, dynamic attributes, or legacy HTML shell patterns that are risky but likely constrained.
+- `Low`: Static-only shell code, false positives, or reviewed sanitizer boundaries that should be documented or covered by tests.
+
+For each group, record:
+
+- File and function/component.
+- Source of untrusted data.
+- Sink and why the existing boundary is insufficient.
+- Remediation approach.
+- Minimum validation or regression test.
+
+Then propose a repair order that starts with high-confidence, high-impact fixes and keeps each batch small enough to review.
+
+## Remediation Patterns
+
+Use these fixes by default:
+
+- Build DOM nodes with `document.createElement(...)` and set untrusted text with `textContent`.
+- Attach behavior with `addEventListener(...)`, not inline handler attributes.
+- Assign inert values through `dataset` or `setAttribute(...)` only after validating the attribute context.
+- Normalize dynamic links with an existing URL sanitizer or a small local helper before assigning `href` or `src`.
+- Render markdown as `DOMPurify.sanitize(marked.parse(...))` before assigning to an HTML sink.
+- Keep static modal/card/table shells fully static, then populate untrusted fields with DOM APIs.
+- Remove unnecessary `Markup(...)` and Jinja `|safe`; if HTML is required, make the sanitizer boundary explicit and covered by tests.
+
+Avoid broad mechanical rewrites. Preserve behavior, accessibility, Bootstrap state classes, and local asset references.
+
+## Verification
+
+After each remediation batch, run the narrowest reliable checks first, then broaden before final reporting:
+
+- `node --check <changed-js-file>` for changed JavaScript files.
+- `python -m py_compile <changed-python-file>` for changed Python files.
+- Relevant functional or UI tests for the edited workflow.
+- `python scripts/check_xss_sinks.py --full-file <changed-files>` for edited application JS/HTML/Python files.
+- Full audit rerun before completion when the user asked for a complete fix pass:
+
+```powershell
+$xssFiles = git ls-files "application/**/*.js" "application/**/*.html" "application/**/*.py"
+python scripts/check_xss_sinks.py --full-file $xssFiles
+```
+
+- `git -c core.whitespace=blank-at-eol,blank-at-eof,space-before-tab,cr-at-eol diff --check`.
+
+If a check cannot run locally, explain why and include the remaining risk.
+
+## Output Expectations
+
+When complete, report:
+
+- Scope scanned and whether this was full-repo, target-path, scan-only, or remediation mode.
+- Findings grouped by severity, including false positives and reviewed exceptions.
+- Files changed and the rendering safety pattern used.
+- Validation commands run and pass/fail status.
+- Remaining risks, tests that were skipped, and any follow-up that needs a product or security decision.

-# Overview
-
-The **Simple Chat Application** is a comprehensive, web-based platform designed to facilitate secure and context-aware interactions with generative AI models, specifically leveraging **Azure OpenAI**. Its central feature is **Retrieval-Augmented Generation (RAG)**, which significantly enhances AI interactions by allowing users to ground conversations in their own data. Users can upload personal ("Your Workspace") or shared group ("Group Workspaces") documents, which are processed using **Azure AI Document Intelligence**, chunked intelligently based on content type, vectorized via **Azure OpenAI Embeddings**, and indexed into **Azure AI Search** for efficient hybrid retrieval (semantic + keyword).
-
-Built with modularity in mind, the application offers a suite of powerful **optional features** that can be enabled via administrative settings. These include integrating **Azure AI Content Safety** for governance, providing **Image Generation** capabilities (DALL-E), processing **Video** (via Azure Video Indexer) and **Audio** (via Azure Speech Service) files for RAG, implementing **Document Classification** schemes, collecting **User Feedback**, enabling **Conversation Archiving** for compliance, extracting **AI-driven Metadata**, and offering **Enhanced Citations** linked directly to source documents stored in Azure Storage.
-
-The application utilizes **Azure Cosmos DB** for storing conversations, metadata, and settings, and is secured using **Azure Active Directory (Entra ID)** for authentication and fine-grained Role-Based Access Control (RBAC) via App Roles. Designed for enterprise use, it runs reliably on **Azure App Service** and supports deployment in both **Azure Commercial** and **Azure Government** cloud environments, offering a versatile tool for knowledge discovery, content generation, and collaborative AI-powered tasks within a secure, customizable, and Azure-native framework.

-## Quick Deploy
-
-[Detailed deployment Guide](./deployers/bicep/README.md)
-
-If you prefer a PowerShell and Azure CLI driven deployment without AZD, or you want more script-level control over deployment and recovery steps, see [deployers/azurecli/README.md](./deployers/azurecli/README.md).
-
-### Prerequisites
-
-Install these tools before starting the deployment flow:
-
-1. Azure CLI
-    Download: https://learn.microsoft.com/cli/azure/install-azure-cli
-2. Azure Developer CLI (`azd`)
-    Download: https://learn.microsoft.com/azure/developer/azure-developer-cli/install-azd
-3. PowerShell 7
-    Download: https://learn.microsoft.com/powershell/scripting/install/installing-powershell
-4. Visual Studio Code
-    Download: https://code.visualstudio.com/download
-
-Shell guidance:
-
-- This quick-start section uses PowerShell examples.
-- Windows users can run the commands in PowerShell.
-- Linux and macOS users can run the PowerShell scripts by using PowerShell 7 with `pwsh`.
-- If you prefer bash for the surrounding shell commands, use the shell-specific examples in [deployers/bicep/README.md](./deployers/bicep/README.md).
-
-Minimum access and setup:
-
-- An Azure subscription where you have Owner or Contributor access for deployment.
-- Permission to create an Entra application registration, or coordination with an Entra admin who can run that step for you.
-- Access to Azure Container Registry Tasks so `azd up` can build the application image in ACR.
-
-### Pre-Configuration:
-
-The following procedure must be completed with a user that has permissions to create an application registration in the users Entra tenant. 
-
-#### Create the application registration:
-
-```powershell
-cd ./deployers
-```
-
-Define your application name and your environment in PowerShell:
-
-```powershell
-$appName = "simplechat"
-$environment = "dev"
-```
-
-If you type `appName = "simplechat"` in PowerShell, PowerShell treats `appName` as a command name. PowerShell variables must start with `$`.
-
-This main README uses PowerShell examples consistently. Linux and macOS users should run the same script with `pwsh`. If you prefer bash for the surrounding shell commands, use the shell-specific examples in [deployers/bicep/README.md](./deployers/bicep/README.md).
-
-The following script will create an Entra Enterprise Application, with an App Registration named *\<appName\>*-*\<environment\>*-ar for the web service called *\<appName\>*-*\<environment\>*-app.  
-
-> [!TIP]
->
-> The web service name may be overriden with the `-AppServceName` parameter. 
-
-> [!TIP]
->
-> A different expiration date for the secret which defaults to 180 days with the `-SecretExpirationDays` parameter.
-
-```powershell
-.\Initialize-EntraApplication.ps1 -AppName $appName -Environment $environment -AppRolesJsonPath "./azurecli/appRegistrationRoles.json"
-```
-
-Linux and macOS example:
-
-```bash
-pwsh ./Initialize-EntraApplication.ps1 -AppName simplechat -Environment dev -AppRolesJsonPath ./azurecli/appRegistrationRoles.json
-```
-
-> [!NOTE]
->
-> Be sure to save this information as it will not be available after the window is closed.*
-
-```========================================
-App Registration Created Successfully!
-Application Name:       <registered application name>
-Client ID:              <clientID>
-Tenant ID:              <tenantID>
-Service Principal ID:   <servicePrincipalId>
-Client Secret:          <clientSecret>
-Secret Expiration:      <yyyy-mm-dd>
-```
-
-In addition, the script will note additional steps that must be taken for the app registration step to be completed.
-
-1.  Grant Admin Consent for API Permissions:
-
-    - Navigate to Azure Portal > Entra ID > App registrations
-    - Find app: *\<registered application name\>*
-    - Go to API permissions
-    - Click 'Grant admin consent for [Tenant]'
-
-2.  Assign Users/Groups to Enterprise Application:
-    - Navigate to Azure Portal > Entra ID > Enterprise applications
-    - Find app: *\<registered application name\>*
-    - Go to Users and groups
-    - Add user/group assignments with appropriate app roles
-
-3.  Store the Client Secret Securely:
-    - Save the client secret in Azure Key Vault or secure credential store
-    - The secret value is shown above and will not be displayed again
-
-#### Configure AZD Environment
-
-Using PowerShell in Visual Studio Code
-
-```powershell
-cd ./deployers
-```
-
-If you work with other Azure clouds, you may need to update your cloud like `azd config set cloud.name AzureUSGovernment` - more information here - [Use Azure Developer CLI in sovereign clouds | Microsoft Learn](https://learn.microsoft.com/en-us/azure/developer/azure-developer-cli/sovereign-clouds)
-
-```powershell
-azd config set cloud.name AzureCloud
-```
-
-This will open a browser window that the user with Owner level permissions to the target subscription will need to authenticate with.
-
-```powershell
-azd auth login
-```
-
-Initialize the AZD project in the current folder before creating or selecting the environment.
-
-```powershell
-azd init
-```
-
-Use the same value for `$environment` that was used in the application registration.
-
-```powershell
-azd env new $environment
-```
-
-Select the new environment
-
-```powershell
-azd env select $environment
-```
-
-This step will begin the deployment process.  
-
-```powershell
-azd up 
-```
-
-## Deployment Runtime Notes
-
-### Container
-> [!NOTE]
->
-> The container deployments of Simple Chat does NOT need this step, when you run `azd up` for new installs or `azd deploy` for updates, the container is configured to run with gunicorn.
-
-- The repo-provided `azd`, Bicep, Terraform, and Azure CLI deployers are **container-based** App Service deployments.
-- For those container deployments, do **not** set an App Service Stack Settings Startup command. 
-    - The container already starts Gunicorn through `application/single_app/Dockerfile`.
-- If your environment needs private or self-signed certificate authorities for outbound TLS checks to internal services, add them during image build using [docs/how-to/docker_customization.md](docs/how-to/docker_customization.md).
-
-### Native Python
-- For **native Python App Service** deployments, deploy the `application/single_app` folder and set the App Service Startup command explicitly.
-
-Native Python deployment references:
-
-- [Manual deployment notes](./docs/reference/deploy/manual_deploy.md)
-- [Manual setup steps](./docs/setup_instructions_manual.md#installing-and-deploying-the-application-code)
-- [VS Code deployment steps](./docs/setup_instructions_manual.md#deploying-via-vs-code-recommended-for-simplicity)
-- [Azure CLI ZIP deploy steps](./docs/setup_instructions_manual.md#deploying-via-azure-cli-zip-deploy)
-
-To set the Startup command in Azure Portal:
-
-1. Go to the App Service.
-2. Open **Settings** > **Configuration** > **Stack Settings**.
-3. Enter the following Startup command.
-4. Save the change, then stop and start the app.
-
-Use this Startup command for native Python App Service deployments:
-
-```bash
-python -m gunicorn -c gunicorn.conf.py app:app
-```
-
-> [!IMPORTANT]
->
-> Running Simple Chat with gunicorn improves the experience with better request handling and concurrency.
-
-## Upgrade Paths
-
-- For a concise upgrade decision guide, see [docs/how-to/upgrade_paths.md](docs/how-to/upgrade_paths.md).
-
-### Container
-- **Container-based upgrades** should usually start with `azd deploy` for code-only changes. Use `azd up` only when the release also changes infrastructure.
-- If your App Service is already configured to pull from ACR and you want image-only rollouts, use the ACR/image refresh approach described in [docs/how-to/upgrade_paths.md](docs/how-to/upgrade_paths.md) instead of treating every release as a full reprovisioning event.
-
-### Native Python
-- **Native Python App Service upgrades** should reuse the manual deployment path, validate the Startup command above, and deploy the `application/single_app` folder with VS Code or Azure CLI ZIP deploy.
-- [Manual native Python upgrade guide](./docs/setup_instructions_manual.md#upgrading-the-application)
-- [Native Python ZIP deploy reference](./docs/setup_instructions_manual.md#deploying-via-azure-cli-zip-deploy)
-- [Native Python deployment notes](./docs/reference/deploy/manual_deploy.md)

-## Features
-
-- **Chat with AI**: Interact with an AI model based on Azure OpenAI’s GPT and Thinking models.
-- **RAG with Hybrid Search**: Upload documents and perform hybrid searches (vector + keyword), retrieving relevant information from your files to augment AI responses.
-- **Document Management**: Upload, store, and manage multiple versions of documents—personal ("Your Workspace") or group-level ("Group Workspaces").
-- **Group Management**: Create and join groups to share access to group-specific documents, enabling collaboration with Role-Based Access Control (RBAC).
-- **Ephemeral (Single-Convo) Documents**: Upload temporary documents available only during the current chat session, without persistent storage in Azure AI Search.
-- **Conversation Archiving (Optional)**: Retain copies of user conversations—even after deletion from the UI—in a dedicated Cosmos DB container for audit, compliance, or legal requirements.
-- **Content Safety (Optional)**: Integrate Azure AI Content Safety to review every user message *before* it reaches AI models, search indexes, or image generation services. Enforce custom filters and compliance policies, with an optional `SafetyAdmin` role for viewing violations.
-- **Feedback System (Optional)**: Allow users to rate AI responses (thumbs up/down) and provide contextual comments on negative feedback. Includes user and admin dashboards, governed by an optional `FeedbackAdmin` role.
-- **Bing Web Search (Optional)**: Augment AI responses with live Bing search results, providing up-to-date information. Configurable via Admin Settings.
-- **Image Generation (Optional)**: Enable on-demand image creation using Azure OpenAI's DALL-E models, controlled via Admin Settings.
-- **Video Extraction (Optional)**: Utilize Azure Video Indexer to transcribe speech and perform Optical Character Recognition (OCR) on video frames. Segments are timestamp-chunked for precise retrieval and enhanced citations linking back to the video timecode.
-- **Audio Extraction (Optional)**: Leverage Azure Speech Service to transcribe audio files into timestamped text chunks, making audio content searchable and enabling enhanced citations linked to audio timecodes.
-- **Document Classification (Optional)**: Admins define custom classification types and associated colors. Users tag uploaded documents with these labels, which flow through to AI conversations, providing lineage and insight into data sensitivity or type.
-- **Enhanced Citation (Optional)**: Store processed, chunked files in Azure Storage (organized into user- and document-scoped folders). Display interactive citations in the UI—showing page numbers or timestamps—that link directly to the source document preview.
-- **Metadata Extraction (Optional)**: Apply an AI model (configurable GPT model via Admin Settings) to automatically generate keywords, two-sentence summaries, and infer author/date for uploaded documents. Allows manual override for richer search context.
-- **File Processing Logs (Optional)**: Enable verbose logging for all ingestion pipelines (workspaces and ephemeral chat uploads) to aid in debugging, monitoring, and auditing file processing steps.
-- **Redis Cache (Optional)**: Integrate Azure Cache for Redis to provide a distributed, high-performance session store. This enables true horizontal scaling and high availability by decoupling user sessions from individual app instances.
-- **SQL Database Agents (Optional)**: Connect agents to Azure SQL or other SQL databases through configurable SQL Query and SQL Schema plugins. Database schema is automatically discovered and injected into agent instructions at load time, enabling agents to answer natural language questions by generating and executing SQL queries without requiring users to know table or column names.
-- **Authentication & RBAC**: Secure access via Azure Active Directory (Entra ID) using MSAL. Supports Managed Identities for Azure service authentication, group-based controls, and custom application roles (`Admin`, `User`, `CreateGroup`, `SafetyAdmin`, `FeedbackAdmin`).

+
+# Overview
+
+The **Simple Chat Application** is a comprehensive, web-based platform designed to facilitate secure and context-aware interactions with generative AI models, specifically leveraging **Azure OpenAI**. Its central feature is **Retrieval-Augmented Generation (RAG)**, which significantly enhances AI interactions by allowing users to ground conversations in their own data. Users can upload personal ("Your Workspace") or shared group ("Group Workspaces") documents, which are processed using **Azure AI Document Intelligence**, chunked intelligently based on content type, vectorized via **Azure OpenAI Embeddings**, and indexed into **Azure AI Search** for efficient hybrid retrieval (semantic + keyword).
+
+Built with modularity in mind, the application offers a suite of powerful **optional features** that can be enabled via administrative settings. These include integrating **Azure AI Content Safety** for governance, providing **Image Generation** capabilities (DALL-E), processing **Video** (via Azure Video Indexer) and **Audio** (via Azure Speech Service) files for RAG, implementing **Document Classification** schemes, collecting **User Feedback**, enabling **Conversation Archiving** for compliance, extracting **AI-driven Metadata**, and offering **Enhanced Citations** linked directly to source documents stored in Azure Storage.
+
+The application utilizes **Azure Cosmos DB** for storing conversations, metadata, and settings, and is secured using **Azure Active Directory (Entra ID)** for authentication and fine-grained Role-Based Access Control (RBAC) via App Roles. Designed for enterprise use, it runs reliably on **Azure App Service** and supports deployment in both **Azure Commercial** and **Azure Government** cloud environments, offering a versatile tool for knowledge discovery, content generation, and collaborative AI-powered tasks within a secure, customizable, and Azure-native framework.

+
+## Quick Deploy
+
+[Detailed deployment Guide](./deployers/bicep/README.md)
+
+If you prefer a PowerShell and Azure CLI driven deployment without AZD, or you want more script-level control over deployment and recovery steps, see [deployers/azurecli/README.md](./deployers/azurecli/README.md).
+
+### Prerequisites
+
+Install these tools before starting the deployment flow:
+
+1. Azure CLI
+    Download: https://learn.microsoft.com/cli/azure/install-azure-cli
+2. Azure Developer CLI (`azd`)
+    Download: https://learn.microsoft.com/azure/developer/azure-developer-cli/install-azd
+3. Python 3.12
+    Download: https://www.python.org/downloads/
+    The AZD preprovision and postprovision hooks in [deployers/azure.yaml](./deployers/azure.yaml) run Python scripts for prerequisite validation, dependency installation, and post-provision configuration. Make sure `python` is available on Windows and `python3` is available on Linux/macOS before running `azd up`.
+4. PowerShell 7
+    Download: https://learn.microsoft.com/powershell/scripting/install/installing-powershell
+5. Visual Studio Code
+    Download: https://code.visualstudio.com/download
+
+Shell guidance:
+
+- This quick-start section uses PowerShell examples.
+- Windows users can run the commands in PowerShell.
+- Linux and macOS users can run the PowerShell scripts by using PowerShell 7 with `pwsh`.
+- If you prefer bash for the surrounding shell commands, use the shell-specific examples in [deployers/bicep/README.md](./deployers/bicep/README.md).
+
+Minimum access and setup:
+
+- An Azure subscription where you have Owner or Contributor access for deployment.
+- Permission to create an Entra application registration, or coordination with an Entra admin who can run that step for you.
+- Access to Azure Container Registry Tasks so `azd up` can build the application image in ACR.
+
+### Pre-Configuration:
+
+The following procedure must be completed with a user that has permissions to create an application registration in the users Entra tenant.
+
+#### Create the application registration:
+
+```powershell
+cd ./deployers
+```
+
+Define your application name and your environment in PowerShell:
+
+```powershell
+$appName = "simplechat"
+$environment = "dev"
+```
+
+If you type `appName = "simplechat"` in PowerShell, PowerShell treats `appName` as a command name. PowerShell variables must start with `$`.
+
+This main README uses PowerShell examples consistently. Linux and macOS users should run the same script with `pwsh`. If you prefer bash for the surrounding shell commands, use the shell-specific examples in [deployers/bicep/README.md](./deployers/bicep/README.md).
+
+The following script will create an Entra Enterprise Application, with an App Registration named *\<appName\>*-*\<environment\>*-ar for the web service called *\<appName\>*-*\<environment\>*-app.
+
+> [!TIP]
+>
+> The web service name may be overriden with the `-AppServceName` parameter.
+
+> [!TIP]
+>
+> A different expiration date for the secret which defaults to 180 days with the `-SecretExpirationDays` parameter.
+
+```powershell
+.\Initialize-EntraApplication.ps1 -AppName $appName -Environment $environment -AppRolesJsonPath "./azurecli/appRegistrationRoles.json"
+```
+
+By default, the script saves the app registration values that `azd up` needs into the resolved AZD environment:
+
+- `ENTERPRISE_APP_CLIENT_ID`
+- `ENTERPRISE_APP_SERVICE_PRINCIPAL_ID`
+- `ENTERPRISE_APP_CLIENT_SECRET`
+
+Use `-AzdEnvironmentName <name>` to target a specific AZD environment, or `-SkipAzdEnvironmentUpdate` when running the registration as a standalone/manual workflow.
+
+Linux and macOS example:
+
+```bash
+pwsh ./Initialize-EntraApplication.ps1 -AppName simplechat -Environment dev -AppRolesJsonPath ./azurecli/appRegistrationRoles.json
+```
+
+> [!NOTE]
+>
+> If the script cannot update the AZD environment, save the displayed values manually and set them later with `azd env set`.
+
+```========================================
+App Registration Created Successfully!
+Application Name:       <registered application name>
+Client ID:              <clientID>
+Tenant ID:              <tenantID>
+Service Principal ID:   <servicePrincipalId>
+Client Secret:          <clientSecret>
+Secret Expiration:      <yyyy-mm-dd>
+```
+
+In addition, the script will note additional steps that must be taken for the app registration step to be completed.
+
+1.  Grant Admin Consent for API Permissions:
+
+    - Navigate to Azure Portal > Entra ID > App registrations
+    - Find app: *\<registered application name\>*
+    - Go to API permissions
+    - Click 'Grant admin consent for [Tenant]'
+
+2.  Assign Users/Groups to Enterprise Application:
+    - Navigate to Azure Portal > Entra ID > Enterprise applications
+    - Find app: *\<registered application name\>*
+    - Go to Users and groups
+    - Add user/group assignments with appropriate app roles
+
+3.  Store the Client Secret Securely:
+    - Save the client secret in Azure Key Vault or secure credential store
+    - The secret value is shown above and will not be displayed again
+
+#### Configure AZD Environment
+
+Using PowerShell in Visual Studio Code
+
+```powershell
+cd ./deployers
+```
+
+If you work with other Azure clouds, you may need to update your cloud like `azd config set cloud.name AzureUSGovernment` - more information here - [Use Azure Developer CLI in sovereign clouds | Microsoft Learn](https://learn.microsoft.com/en-us/azure/developer/azure-developer-cli/sovereign-clouds)
+
+```powershell
+azd config set cloud.name AzureCloud
+```
+
+This will open a browser window that the user with Owner level permissions to the target subscription will need to authenticate with.
+
+```powershell
+azd auth login
+```
+
+Initialize the AZD project in the current folder before creating or selecting the environment.
+
+```powershell
+azd init
+```
+
+Use the same value for `$environment` that was used in the application registration.
+
+```powershell
+azd env new $environment
+```
+
+Select the new environment
+
+```powershell
+azd env select $environment
+```
+
+This step will begin the deployment process.
+
+```powershell
+azd up
+```
+
+## Deployment Runtime Notes
+
+### Container
+> [!NOTE]
+>
+> The container deployments of Simple Chat does NOT need this step, when you run `azd up` for new installs or `azd deploy` for updates, the container is configured to run with gunicorn.
+
+- The repo-provided `azd`, Bicep, Terraform, and Azure CLI deployers are **container-based** App Service deployments.
+- For those container deployments, do **not** set an App Service Stack Settings Startup command.
+    - The container already starts Gunicorn through `application/single_app/Dockerfile`.
+- If your environment needs private or self-signed certificate authorities for outbound TLS checks to internal services, add them during image build using [docs/how-to/docker_customization.md](docs/how-to/docker_customization.md).
+
+### Native Python
+- For **native Python App Service** deployments, deploy the `application/single_app` folder and set the App Service Startup command explicitly.
+
+Native Python deployment references:
+
+- [Manual deployment notes](./docs/reference/deploy/manual_deploy.md)
+- [Manual setup steps](./docs/setup_instructions_manual.md#installing-and-deploying-the-application-code)
+- [VS Code deployment steps](./docs/setup_instructions_manual.md#deploying-via-vs-code-recommended-for-simplicity)
+- [Azure CLI ZIP deploy steps](./docs/setup_instructions_manual.md#deploying-via-azure-cli-zip-deploy)
+
+To set the Startup command in Azure Portal:
+
+1. Go to the App Service.
+2. Open **Settings** > **Configuration** > **Stack Settings**.
+3. Enter the following Startup command.
+4. Save the change, then stop and start the app.
+
+Use this Startup command for native Python App Service deployments:
+
+```bash
+python -m gunicorn -c gunicorn.conf.py app:app
+```
+
+> [!IMPORTANT]
+>
+> Running Simple Chat with gunicorn improves the experience with better request handling and concurrency.
+
+## Upgrade Paths
+
+- For a concise upgrade decision guide, see [docs/how-to/upgrade_paths.md](docs/how-to/upgrade_paths.md).
+
+### Container
+- **Container-based upgrades** should usually start with `azd deploy` for code-only changes. Use `azd up` only when the release also changes infrastructure.
+- If your App Service is already configured to pull from ACR and you want image-only rollouts, use the ACR/image refresh approach described in [docs/how-to/upgrade_paths.md](docs/how-to/upgrade_paths.md) instead of treating every release as a full reprovisioning event.
+
+### Native Python
+- **Native Python App Service upgrades** should reuse the manual deployment path, validate the Startup command above, and deploy the `application/single_app` folder with VS Code or Azure CLI ZIP deploy.
+- [Manual native Python upgrade guide](./docs/setup_instructions_manual.md#upgrading-the-application)
+- [Native Python ZIP deploy reference](./docs/setup_instructions_manual.md#deploying-via-azure-cli-zip-deploy)
+- [Native Python deployment notes](./docs/reference/deploy/manual_deploy.md)

+# Create Custom Pages
+
+Custom Pages let deployment teams add trusted pages under `/custom` without editing the core SimpleChat route table. Use this guide for the built-in Request Access page and the three supported patterns: simple HTML, static HTML/CSS/JS, and Python-backed Jinja/API pages.
+
+Custom Pages are trusted deployment-time content. They are not runtime user uploads. Static page metadata is stored in the `custom_pages` Cosmos container, while files live in the deployed artifact under `application/single_app/custom_pages/`.
+
+## Before You Start
+
+1. Deploy files under `application/single_app/custom_pages/` in the matching folders: `html`, `css`, `js`, `assets`, `json`, and `python`.
+2. Enable Custom Pages in Admin Settings > Custom Pages.
+3. Acknowledge the restart requirement when enabling the feature from a disabled state.
+4. Restart the App Service or local Flask process after deploying new files or Python-backed pages.
+
+The canonical route format is `/custom/<slug>`. Static-looking aliases such as `/custom/<slug>.html` are also supported.
+
+## Built-In Request Access Page
+
+SimpleChat includes a practical static page that helps signed-in users request the base `User` role. It is not automatically inserted into Cosmos DB. Admins can instantiate it from Admin Settings > Custom Pages by selecting **Add Request Access Page**.
+
+The one-click action creates static page metadata and enables the access-denied button on the home page for signed-in users who do not yet have an app role.
+
+Request Access metadata:
+
+| Field | Value |
+| --- | --- |
+| Slug | `request-access` |
+| Title | `Request SimpleChat Access` |
+| Description | `A signed-in access request page for users who need the base User role.` |
+| Navigation Label | `Request Access` |
+| Bootstrap Icon | `bi-person-plus` |
+| Order | `5` |
+| Access Level | `Any signed-in user` |
+| Allowed Roles | leave blank |
+| HTML File | `request-access.html` |
+| CSS Files | add `request-access.css` |
+| JavaScript Files | no files |
+| Asset Files | no files |
+| JSON Files | no files |
+| Enabled | on |
+| Show in Navigation | off |
+| Open in New Tab | off |
+
+The page opens the user's email client with:
+
+- To: `accessrequest@example.com`
+- Subject: `SimpleChat Access Request`
+- Body: `Please grant me the user role in simplechat so that I may start using this wonderful tool`
+
+## Access Levels
+
+Static page metadata has an Access Level field:
+
+- `App users only`: requires the signed-in user to have `User` or `Admin` before page-specific roles are checked.
+- `Any signed-in user`: requires login, but does not require the base app role before page-specific roles are checked.
+
+Use `Any signed-in user` sparingly. It is intended for bootstrap flows like Request Access. Most custom pages should stay `App users only`.
+
+## Pattern 1: Simple HTML Page
+
+Use this when the page only needs trusted HTML and Bootstrap classes already available from the SimpleChat shell.
+
+Place the HTML fragment in `application/single_app/custom_pages/html/`.
+
+Example file: `example-simple.html`
+
+Sample source: `docs/how-to/custom_pages_examples/simple-html/example-simple.html`
+
+Metadata editor values:
+
+| Field | Value |
+| --- | --- |
+| Slug | `example-simple` |
+| Title | `Simple HTML Example` |
+| Description | `A minimal custom page loaded from a trusted HTML fragment.` |
+| Navigation Label | `Simple HTML` |
+| Bootstrap Icon | `bi-file-earmark-text` |
+| Order | `10` |
+| Allowed Roles | leave blank for all signed-in users, or use a role such as `User` |
+| HTML File | `example-simple.html` |
+| CSS Files | no files |
+| JavaScript Files | no files |
+| Asset Files | no files |
+| JSON Files | no files |
+| Enabled | on |
+| Show in Navigation | on |
+| Open in New Tab | off |
+
+After saving metadata, test `/custom/example-simple` and `/custom/example-simple.html`.
+
+## Pattern 2: Static HTML, CSS, and JavaScript Page
+
+Use this when a static page needs page-specific styling or client-side behavior.
+
+Place files in these folders:
+
+- HTML in `application/single_app/custom_pages/html/`
+- CSS in `application/single_app/custom_pages/css/`
+- JavaScript modules in `application/single_app/custom_pages/js/`
+- Images and other static files in `application/single_app/custom_pages/assets/`
+- JSON data in `application/single_app/custom_pages/json/`
+
+Example files:
+
+- `html/example-static.html`
+- `css/example-static.css`
+- `js/example-static.js`
+- `assets/cat.mp4`
+
+Sample source folder: `docs/how-to/custom_pages_examples/static-html-css-js/`
+
+Metadata editor values:
+
+| Field | Value |
+| --- | --- |
+| Slug | `example-static` |
+| Title | `Static HTML with CSS/JS Example` |
+| Description | `A custom static page with deployed HTML, CSS, and JavaScript.` |
+| Navigation Label | `Static Example` |
+| Bootstrap Icon | `bi-window` |
+| Order | `20` |
+| Allowed Roles | leave blank for all signed-in users, or use a role such as `User` |
+| HTML File | `example-static.html` |
+| CSS Files | add `example-static.css` |
+| JavaScript Files | add `example-static.js` |
+| Asset Files | add `cat.mp4` |
+| JSON Files | add only JSON or CSV files the page must fetch through `/custom/assets/...` |
+| Enabled | on |
+| Show in Navigation | on |
+| Open in New Tab | off |
+
+The metadata designer stores CSS, JavaScript, asset, and JSON references as arrays. Add one file at a time in the modal so the page only serves files explicitly declared by metadata.
+
+## Pattern 3: Python-Backed Jinja Page with Backend API
+
+Use this when the page needs server-side rendering, access to request context, or a custom backend operation.
+
+Place the Python extension in `application/single_app/custom_pages/python/`. The extension must subclass `CustomPageExtension` and provide metadata with a unique `slug`. It can render a template from `custom_pages/html/` and handle API operations through `/api/custom/<slug>/<operation>`.
+
+Example files:
+
+- `python/example_python_dashboard.py`
+- `html/example-python-dashboard.html`
+- `css/example-python-dashboard.css`
+- `js/example-python-dashboard.js`
+
+Sample source folder: `docs/how-to/custom_pages_examples/python-jinja-api/`
+
+Do not create Python-backed pages in the metadata editor. Python-backed pages are discovered from code at app startup. Restart the App Service after deploying or changing Python-backed page files.
+
+The example page appears at `/custom/example-python-dashboard`, and its sample API endpoint is `/api/custom/example-python-dashboard/status`.
+
+## Role Behavior
+
+Leave Allowed Roles blank to allow any signed-in user. Use role names such as `User` to restrict access. `Admin` satisfies `User` because `User` is the base application role. For any other role, every user, including admins, must have at least one exact matching role in their current SimpleChat session. A role name that does not exist in the app registration will not appear in user tokens, so it will deny access unless the role is otherwise present in the session.
+
+## Troubleshooting
+
+- If a static page does not appear in navigation, verify the metadata is enabled and `Show in Navigation` is on.
+- If a static page returns `Not Found`, verify the slug, HTML file name, feature toggle, and App Service restart state.
+- If CSS or JavaScript does not load, verify the file is listed in metadata and exists in the matching folder.
+- If a Python-backed page does not appear, restart the App Service after deploying the Python file.
+- If `/custom/<slug>` works but `/custom/<slug>.html` does not, restart the app to load the latest route registration.

+Image generation is available as an opt-in user action. Do not generate or embed images directly in the assistant answer. When one or more generated images would materially help the user, include compact fenced `{INLINE_IMAGE_PROPOSAL_BLOCK_LANGUAGE}` JSON proposals inline at the point where each visual belongs. The browser will render each block as an approval card with approve, cancel, and edit controls.
+
+Use this exact fenced block shape and valid JSON only:
+```{INLINE_IMAGE_PROPOSAL_BLOCK_LANGUAGE}
+{{
+  "version": 1,
+  "visualId": "short_stable_id",
+  "title": "Short image title",
+  "description": "One sentence describing the proposed image.",
+  "prompt": "Detailed image-generation prompt with subject, composition, labels, style, accessibility/readability constraints, and any source context needed.",
+  "visualType": "timeline|diagram|illustration|infographic|map|scene|other",
+  "slideNumber": 9,
+  "context": "Brief source context"
+}}
+```
+
+Rules:
+- Only propose images when they are useful; omit the block when text alone is better.
+- Place each `{INLINE_IMAGE_PROPOSAL_BLOCK_LANGUAGE}` block immediately after the paragraph, bullet, slide section, or visual suggestion it supports. Do not collect image proposals at the end unless the end is the relevant section.
+- For slide decks, keep each proposal inside the slide it supports, directly after the slide's visual suggestion, include list, or speaker note.
+- Suggest zero, one, or multiple images based on value. One strong image proposal is fine; multiple distinct proposals are appropriate when several slides or sections benefit from visuals.
+- Avoid decorative duplicates and avoid proposing images that do not directly support the surrounding content.
+- Keep each prompt self-contained and under {IMAGE_PROPOSAL_PROMPT_MAX_LENGTH} characters.
+- The user must approve before generation; never state that an image has already been created.
+- Do not include secrets, private URLs, or unsupported instructions in the prompt.

The pre-defined properties are listed in this documentation as\n * 'Observable Properties', and have their own accessors; for example,\n * {@link module:ol/Map~Map} has a `target` property, accessed with\n * `getTarget()` and changed with `setTarget()`. Not all properties are however\n * settable. There are also general-purpose accessors `get()` and `set()`.

For example, {@link module:ol/View~View} has a\n * `center` property, so `view.on('change:center', function(evt) {...});` would\n * call the function whenever the value of the center property changes. Within\n * the function, `evt.target` would be the view, so `evt.target.getCenter()`\n * would return the new center.\n *\n * You can add your own observable properties with\n * `object.set('prop', 'value')`, and retrieve that with `object.get('prop')`.\n * You can listen for changes on that property value with\n * `object.on('change:prop', listener)`. You can get a list of all\n * properties with {@link module:ol/Object~BaseObject#getProperties}.\n *\n * Note that the observable properties are separate from standard JS properties.\n * You can, for example, give your map object a title with\n * `map.title='New title'` and with `map.set('title', 'Another title')`. The\n * first will be a `hasOwnProperty`; the second will appear in\n * `getProperties()`. Only the second is observable.\n *\n * Properties can be deleted by using the unset method.

If you want to add\n * one for creating default tile grids, you can add it after the Projection\n * object has been created with `setExtent`, for example,\n * `get('EPSG:1234').setExtent(extent)`.\n *\n * In addition to Proj4js support, any transform functions can be added with\n * {@link module:ol/proj.addCoordinateTransforms}. To use this, you must first create\n * a {@link module:ol/proj/Projection~Projection} object for the new projection and add it with\n * {@link module:ol/proj.addProjection}. You can then add the forward and inverse\n * functions with {@link module:ol/proj.addCoordinateTransforms}. See\n * examples/wms-custom-proj for an example of this.\n *\n * Note that if no transforms are needed and you only need to define the\n * projection, just add a {@link module:ol/proj/Projection~Projection} with\n * {@link module:ol/proj.addProjection}.

Still, the `setZoom` and `getZoom`\n * methods are available, as well as `getResolutionForZoom` and\n * `getZoomForResolution` to switch from one system to the other.\n *\n * ### The constraints\n *\n * `setCenter`, `setResolution` and `setRotation` can be used to change the\n * states of the view, but any constraint defined in the constructor will\n * be applied along the way.\n *\n * A View object can have a *resolution constraint*, a *rotation constraint*\n * and a *center constraint*.\n *\n * The *resolution constraint* typically restricts min/max values and\n * snaps to specific resolutions. It is determined by the following\n * options: `resolutions`, `maxResolution`, `maxZoom` and `zoomFactor`.\n * If `resolutions` is set, the other three options are ignored. See\n * documentation for each option for more information. By default, the view\n * only has a min/max restriction and allow intermediary zoom levels when\n * pinch-zooming for example.\n *\n * The *rotation constraint* snaps to specific angles. It is determined\n * by the following options: `enableRotation` and `constrainRotation`.\n * By default rotation is allowed and its value is snapped to zero when approaching the\n * horizontal.\n *\n * The *center constraint* is determined by the `extent` option. By\n * default the view center is not constrained at all.\n *\n * ### Changing the view state\n *\n * It is important to note that `setZoom`, `setResolution`, `setCenter` and\n * `setRotation` are subject to the above mentioned constraints. As such, it\n * may sometimes not be possible to know in advance the resulting state of the\n * View. For example, calling `setResolution(10)` does not guarantee that\n * `getResolution()` will return `10`.\n *\n * A consequence of this is that, when applying a delta on the view state, one\n * should use `adjustCenter`, `adjustRotation`, `adjustZoom` and `adjustResolution`\n * rather than the corresponding setters. This will let view do its internal\n * computations. Besides, the `adjust*` methods also take an `anchor`\n * argument which allows specifying an origin for the transformation.\n *\n * ### Interacting with the view\n *\n * View constraints are usually only applied when the view is *at rest*, meaning that\n * no interaction or animation is ongoing. As such, if the user puts the view in a\n * state that is not equivalent to a constrained one (e.g. rotating the view when\n * the snap angle is 0), an animation will be triggered at the interaction end to\n * put back the view to a stable state;\n *\n * @api\n */\nclass View extends BaseObject {\n  /**\n   * @param {ViewOptions} [options] View options.\n   */\n  constructor(options) {\n    super();\n\n    /***\n     * @type {ViewOnSignature<import(\"./events\").EventsKey>}\n     */\n    this.on;\n\n    /***\n     * @type {ViewOnSignature<import(\"./events\").EventsKey>}\n     */\n    this.once;\n\n    /***\n     * @type {ViewOnSignature<void>}\n     */\n    this.un;\n\n    options = Object.assign({}, options);\n\n    /**\n     * @private\n     * @type {Array<number>}\n     */\n    this.hints_ = [0, 0];\n\n    /**\n     * @private\n     * @type {Array<Array<Animation>>}\n     */\n    this.animations_ = [];\n\n    /**\n     * @private\n     * @type {number|undefined}\n     */\n    this.updateAnimationKey_;\n\n    /**\n     * @private\n     * @const\n     * @type {import(\"./proj/Projection.js\").default}\n     */\n    this.projection_ = createProjection(options.projection, 'EPSG:3857');\n\n    /**\n     * @private\n     * @type {import(\"./size.js\").Size}\n     */\n    this.viewportSize_ = [100, 100];\n\n    /**\n     * @private\n     * @type {import(\"./coordinate.js\").Coordinate|undefined}\n     */\n    this.targetCenter_ = null;\n\n    /**\n     * @private\n     * @type {number|undefined}\n     */\n    this.targetResolution_;\n\n    /**\n     * @private\n     * @type {number|undefined}\n     */\n    this.targetRotation_;\n\n    /**\n     * @private\n     * @type {import(\"./coordinate.js\").Coordinate}\n     */\n    this.nextCenter_ = null;\n\n    /**\n     * @private\n     * @type {number}\n     */\n    this.nextResolution_;\n\n    /**\n     * @private\n     * @type {number}\n     */\n    this.nextRotation_;\n\n    /**\n     * @private\n     * @type {import(\"./coordinate.js\").Coordinate|undefined}\n     */\n    this.cancelAnchor_ = undefined;\n\n    if (options.projection) {\n      disableCoordinateWarning();\n    }\n    if (options.center) {\n      options.center = fromUserCoordinate(options.center, this.projection_);\n    }\n    if (options.extent) {\n      options.extent = fromUserExtent(options.extent, this.projection_);\n    }\n\n    this.applyOptions_(options);\n  }\n\n  /**\n   * Set up the view with the given options.\n   * @param {ViewOptions} options View options.\n   */\n  applyOptions_(options) {\n    const properties = Object.assign({}, options);\n    for (const key in ViewProperty) {\n      delete properties[key];\n    }\n    this.setProperties(properties, true);\n\n    const resolutionConstraintInfo = createResolutionConstraint(options);\n\n    /**\n     * @private\n     * @type {number}\n     */\n    this.maxResolution_ = resolutionConstraintInfo.maxResolution;\n\n    /**\n     * @private\n     * @type {number}\n     */\n    this.minResolution_ = resolutionConstraintInfo.minResolution;\n\n    /**\n     * @private\n     * @type {number}\n     */\n    this.zoomFactor_ = resolutionConstraintInfo.zoomFactor;\n\n    /**\n     * @private\n     * @type {Array<number>|undefined}\n     */\n    this.resolutions_ = options.resolutions;\n\n    /**\n     * @type {Array<number>|undefined}\n     * @private\n     */\n    this.padding_ = options.padding;\n\n    /**\n     * @private\n     * @type {number}\n     */\n    this.minZoom_ = resolutionConstraintInfo.minZoom;\n\n    const centerConstraint = createCenterConstraint(options);\n    const resolutionConstraint = resolutionConstraintInfo.constraint;\n    const rotationConstraint = createRotationConstraint(options);\n\n    /**\n     * @private\n     * @type {Constraints}\n     */\n    this.constraints_ = {\n      center: centerConstraint,\n      resolution: resolutionConstraint,\n      rotation: rotationConstraint,\n    };\n\n    this.setRotation(options.rotation !== undefined ? options.rotation : 0);\n    this.setCenterInternal(\n      options.center !== undefined ? options.center : null,\n    );\n    if (options.resolution !== undefined) {\n      this.setResolution(options.resolution);\n    } else if (options.zoom !== undefined) {\n      this.setZoom(options.zoom);\n    }\n  }\n\n  /**\n   * Padding (in css pixels).\n   * If the map viewport is partially covered with other content (overlays) along\n   * its edges, this setting allows to shift the center of the viewport away from that\n   * content.

If `haystack` is an array of strings, use the `literal` operator to disambiguate from an expression:\n *     `['literal', ['abc', 'def', 'ghi']]`\n *\n * * Conversion operators:\n *   * `['array', value1, ...valueN]` creates a numerical array from `number` values; please note that the amount of\n *     values can currently only be 2, 3 or 4 (WebGL only).\n *   * `['color', red, green, blue, alpha]` or `['color', shade, alpha]` creates a `color` value from `number` values;\n *     the `alpha` parameter is optional; if not specified, it will be set to 1 (WebGL only).\n *     Note: `red`, `green` and `blue` or `shade` components must be values between 0 and 255; `alpha` between 0 and 1.\n *   * `['palette', index, colors]` picks a `color` value from an array of colors using the given index; the `index`\n *     expression must evaluate to a number; the items in the `colors` array must be strings with hex colors\n *     (e.g. `'#86A136'`), colors using the rgba[a] functional notation (e.g. `'rgb(134, 161, 54)'` or `'rgba(134, 161, 54, 1)'`),\n *     named colors (e.g. `'red'`), or array literals with 3 ([r, g, b]) or 4 ([r, g, b, a]) values (with r, g, and b\n *     in the 0-255 range and a in the 0-1 range) (WebGL only).\n *   * `['to-string', value]` converts the input value to a string.

When `undefined`, a `zIndex` of 0 is assumed\n * for layers that are added to the map's `layers` collection, or `Infinity` when the layer's `setMap()`\n * method was used.\n * @property {number} [minResolution] The minimum resolution (inclusive) at which this layer will be\n * visible.\n * @property {number} [maxResolution] The maximum resolution (exclusive) below which this layer will\n * be visible.\n * @property {number} [minZoom] The minimum view zoom level (exclusive) above which this layer will be\n * visible.\n * @property {number} [maxZoom] The maximum view zoom level (inclusive) at which this layer will\n * be visible.\n * @property {import(\"../render.js\").OrderFunction} [renderOrder] Render order. Function to be used when sorting\n * features before rendering. By default features are drawn in the order that they are created. Use\n * `null` to avoid the sort, but get an undefined draw order.\n * @property {number} [renderBuffer=100] The buffer in pixels around the viewport extent used by the\n * renderer when getting features from the vector source for the rendering or hit-detection.\n * Recommended value: the size of the largest symbol, line width or label.\n * @property {VectorSourceType} [source] Source.\n * @property {import(\"../Map.js\").default} [map] Sets the layer as overlay on a map. The map will not manage\n * this layer in its layers collection, and the layer will be rendered on top. This is useful for\n * temporary layers. The standard way to add a layer to a map and have it managed by the map is to\n * use [map.addLayer()]{@link import(\"../Map.js\").default#addLayer}.\n * @property {boolean|string|number} [declutter=false] Declutter images and text. Any truthy value will enable\n * decluttering. Within a layer, a feature rendered before another has higher priority. All layers with the\n * same `declutter` value will be decluttered together. The priority is determined by the drawing order of the\n * layers with the same `declutter` value. Higher in the layer stack means higher priority. To declutter distinct\n * layers or groups of layers separately, use different truthy values for `declutter`.\n * @property {import(\"../style/Style.js\").StyleLike|import(\"../style/flat.js\").FlatStyleLike|null} [style] Layer style. When set to `null`, only\n * features that have their own style will be rendered. See {@link module:ol/style/Style~Style} for the default style\n * which will be used if this is not set.\n * @property {import(\"./Base.js\").BackgroundColor} [background] Background color for the layer. If not specified, no background\n * will be rendered.\n * @property {boolean} [updateWhileAnimating=false] When set to `true`, feature batches will\n * be recreated during animations. This means that no vectors will be shown clipped, but the\n * setting will have a performance impact for large amounts of vector data. When set to `false`,\n * batches will be recreated when no animation is active.\n * @property {boolean} [updateWhileInteracting=false] When set to `true`, feature batches will\n * be recreated during interactions. See also `updateWhileAnimating`.\n * @property {Object<string, *>} [properties] Arbitrary observable properties.

There are two types of shaders:\n *\n *   Vertex shaders are used to manipulate the position and attribute of *vertices* of rendered primitives (ie. corners of a square).\n *   Outputs are:\n *\n *   `gl_Position`: position of the vertex in screen space\n *\n *   Varyings usually prefixed with `v_` are passed on to the fragment shader\n *\n *   Fragment shaders are used to control the actual color of the pixels drawn on screen. Their only output is `gl_FragColor`.\n *\n *   Both shaders can take *uniforms* or *attributes* as input. Attributes are explained later. Uniforms are common, read-only values that\n *   can be changed at every frame and can be of type float, arrays of float or images.\n *\n *   Shaders must be compiled and assembled into a program like so:\n *   ```js\n *   // here we simply create two shaders and assemble them in a program which is then used\n *   // for subsequent rendering calls; note how a frameState is required to set up a program,\n *   // as several default uniforms are computed from it (projection matrix, zoom level, etc.)\n *   const vertexShader = new WebGLVertex(VERTEX_SHADER);\n *   const fragmentShader = new WebGLFragment(FRAGMENT_SHADER);\n *   const program = this.context.getProgram(fragmentShader, vertexShader);\n *   helper.useProgram(this.program, frameState);\n *   ```\n *\n *   Uniforms are defined using the `uniforms` option and can either be explicit values or callbacks taking the frame state as argument.\n *   You can also change their value along the way like so:\n *   ```js\n *   helper.setUniformFloatValue('u_value', valueAsNumber);\n *   ```\n *\n * ### Defining post processing passes\n *\n *   Post processing* describes the act of rendering primitives to a texture, and then rendering this texture to the final canvas\n *   while applying special effects in screen space.\n *   Typical uses are: blurring, color manipulation, depth of field, filtering...\n *\n *   The `WebGLHelper` class offers the possibility to define post processes at creation time using the `postProcesses` option.\n *   A post process step accepts the following options:\n *\n *   `fragmentShader` and `vertexShader`: text literals in GLSL language that will be compiled and used in the post processing step.\n *   `uniforms`: uniforms can be defined for the post processing steps just like for the main render.\n *   `scaleRatio`: allows using an intermediate texture smaller or higher than the final canvas in the post processing step.\n *     This is typically used in blur steps to reduce the performance overhead by using an already downsampled texture as input.\n *\n *   The {@link module:ol/webgl/PostProcessingPass~WebGLPostProcessingPass} class is used internally, refer to its documentation for more info.\n *\n * ### Binding WebGL buffers and flushing data into them\n *\n *   Data that must be passed to the GPU has to be transferred using {@link module:ol/webgl/Buffer~WebGLArrayBuffer} objects.\n *   A buffer has to be created only once, but must be bound every time the buffer content will be used for rendering.\n *   This is done using {@link bindBuffer}.\n *   When the buffer's array content has changed, the new data has to be flushed to the GPU memory; this is done using\n *   {@link flushBufferData}. Note: this operation is expensive and should be done as infrequently as possible.\n *\n *   When binding an array buffer, a `target` parameter must be given: it should be either {@link module:ol/webgl.ARRAY_BUFFER}\n *   (if the buffer contains vertices data) or {@link module:ol/webgl.ELEMENT_ARRAY_BUFFER} (if the buffer contains indices data).\n *\n *   Examples below:\n *   ```js\n *   // at initialization phase\n *   const verticesBuffer = new WebGLArrayBuffer([], DYNAMIC_DRAW);\n *   const indicesBuffer = new WebGLArrayBuffer([], DYNAMIC_DRAW);\n *\n *   // when array values have changed\n *   helper.flushBufferData(ARRAY_BUFFER, this.verticesBuffer);\n *   helper.flushBufferData(ELEMENT_ARRAY_BUFFER, this.indicesBuffer);\n *\n *   // at rendering phase\n *   helper.bindBuffer(ARRAY_BUFFER, this.verticesBuffer);\n *   helper.bindBuffer(ELEMENT_ARRAY_BUFFER, this.indicesBuffer);\n *   ```\n *\n * ### Specifying attributes\n *\n *   The GPU only receives the data as arrays of numbers. These numbers must be handled differently depending on what it describes (position, texture coordinate...).\n *   Attributes are used to specify these uses. Specify the attribute names with\n *   {@link module:ol/webgl/Helper~WebGLHelper#enableAttributes} (see code snippet below).\n *\n *   Please note that you will have to specify the type and offset of the attributes in the data array. You can refer to the documentation of [WebGLRenderingContext.vertexAttribPointer](https://developer.mozilla.org/en-US/docs/Web/API/WebGLRenderingContext/vertexAttribPointer) for more explanation.\n *   ```js\n *   // here we indicate that the data array has the following structure:\n *   // [posX, posY, offsetX, offsetY, texCoordU, texCoordV, posX, posY, ...]\n *   helper.enableAttributes([\n *     {\n *        name: 'a_position',\n *        size: 2\n *     },\n *     {\n *       name: 'a_offset',\n *       size: 2\n *     },\n *     {\n *       name: 'a_texCoord',\n *       size: 2\n *     }\n *   ])\n *   ```\n *\n * ### Rendering primitives\n *\n *   Once all the steps above have been achieved, rendering primitives to the screen is done using {@link prepareDraw}, {@link drawElements} and {@link finalizeDraw}.\n *   ```js\n *   // frame preparation step\n *   helper.prepareDraw(frameState);\n *\n *   // call this for every data array that has to be rendered on screen\n *   helper.drawElements(0, this.indicesBuffer.getArray().length);\n *\n *   // finalize the rendering by applying post processes\n *   helper.finalizeDraw(frameState);\n *   ```\n *\n * For an example usage of this class, refer to {@link module:ol/renderer/webgl/PointsLayer~WebGLPointsLayerRenderer}.\n */\nclass WebGLHelper extends Disposable {\n  /**\n   * @param {Options} [options] Options.\n   */\n  constructor(options) {\n    super();\n    options = options || {};\n\n    /** @private */\n    this.boundHandleWebGLContextLost_ = this.handleWebGLContextLost.bind(this);\n\n    /** @private */\n    this.boundHandleWebGLContextRestored_ =\n      this.handleWebGLContextRestored.bind(this);\n\n    /**\n     * @private\n     * @type {string}\n     */\n    this.canvasCacheKey_ = options.canvasCacheKey\n      ? getSharedCanvasCacheKey(options.canvasCacheKey)\n      : getUniqueCanvasCacheKey();\n\n    /**\n     * @private\n     * @type {WebGLRenderingContext}\n     */\n    this.gl_ = getOrCreateContext(this.canvasCacheKey_);\n\n    /**\n     * @private\n     * @type {!Object<string, BufferCacheEntry>}\n     */\n    this.bufferCache_ = {};\n\n    /**\n     * @private\n     * @type {Object<string, Object>}\n     */\n    this.extensionCache_ = {};\n\n    /**\n     * @private\n     * @type {WebGLProgram}\n     */\n    this.currentProgram_ = null;\n\n    /**\n     * @private\n     * @type {boolean}\n     */\n    this.needsToBeRecreated_ = false;\n\n    const canvas = this.gl_.canvas;\n\n    canvas.addEventListener(\n      ContextEventType.LOST,\n      this.boundHandleWebGLContextLost_,\n    );\n    canvas.addEventListener(\n      ContextEventType.RESTORED,\n      this.boundHandleWebGLContextRestored_,\n    );\n\n    /**\n     * @private\n     * @type {import(\"../transform.js\").Transform}\n     */\n    this.offsetRotateMatrix_ = createTransform();\n\n    /**\n     * @private\n     * @type {import(\"../transform.js\").Transform}\n     */\n    this.offsetScaleMatrix_ = createTransform();\n\n    /**\n     * @private\n     * @type {Array<number>}\n     */\n    this.tmpMat4_ = create();\n\n    /**\n     * @private\n     * @type {Object<string, Object<string, WebGLUniformLocation>>}\n     */\n    this.uniformLocationsByProgram_ = {};\n\n    /**\n     * @private\n     * @type {Object<string, Object<string, number>>}\n     */\n    this.attribLocationsByProgram_ = {};\n\n    /**\n     * Holds info about custom uniforms used in the post processing pass.\n     * If the uniform is a texture, the WebGL Texture object will be stored here.\n     * @type {Array<UniformInternalDescription>}\n     * @private\n     */\n    this.uniforms_ = [];\n    if (options.uniforms) {\n      this.setUniforms(options.uniforms);\n    }\n\n    /**\n     * An array of PostProcessingPass objects is kept in this variable, built from the steps provided in the\n     * options.

This can be done using\n * {@link module:ol/webgl/ShaderBuilder~ShaderBuilder} utilities. These shaders shall expect a `a_position` attribute\n * containing the screen-space projected center of the quad, as well as a `a_index` attribute\n * whose value (0, 1, 2 or 3) indicates which quad vertex is currently getting processed (see structure below).\n *\n * To include variable attributes in the shaders, you need to declare them using the `attributes` property of\n * the options object like so:\n * ```js\n * new WebGLPointsLayerRenderer(layer, {\n *   attributes: [\n *     {\n *       name: 'size',\n *       callback: function(feature) {\n *         // compute something with the feature\n *       }\n *     },\n *     {\n *       name: 'weight',\n *       callback: function(feature) {\n *         // compute something with the feature\n *       }\n *     },\n *   ],\n *   vertexShader:\n *     // shader using attribute a_weight and a_size\n *   fragmentShader:\n *     // shader using varying v_weight and v_size\n * ```\n *\n * To enable hit detection, you must as well provide dedicated shaders using the `hitVertexShader`\n * and `hitFragmentShader` properties. These shall expect the `a_hitColor` attribute to contain\n * the final color that will have to be output for hit detection to work.\n *\n * The following uniform is used for the main texture: `u_texture`.\n * The following uniform is used for the layer opacity: `u_opacity`.\n *\n * Please note that the main shader output should have premultiplied alpha, otherwise visual anomalies may occur.\n *\n * Points are rendered as quads with the following structure:\n *\n * ```\n *   (u0, v1)      (u1, v1)\n *  [3]----------[2]\n *   |`           |\n *   |  `         |\n *   |    `       |\n *   |      `     |\n *   |        `   |\n *   |          ` |\n *  [0]----------[1]\n *   (u0, v0)      (u1, v0)\n *  ```\n *\n * This uses {@link module:ol/webgl/Helper~WebGLHelper} internally.\n *\n * @api\n */\nclass WebGLPointsLayerRenderer extends WebGLLayerRenderer {\n  /**\n   * @param {import(\"../../layer/Layer.js\").default} layer Layer.\n   * @param {Options} options Options.\n   */\n  constructor(layer, options) {\n    const uniforms = options.uniforms || {};\n    const projectionMatrixTransform = createTransform();\n    uniforms[DefaultUniform.PROJECTION_MATRIX] = projectionMatrixTransform;\n\n    super(layer, {\n      uniforms: uniforms,\n      postProcesses: options.postProcesses,\n    });\n\n    /**\n     * @private\n     */\n    this.sourceRevision_ = -1;\n\n    /**\n     * @private\n     */\n    this.verticesBuffer_ = new WebGLArrayBuffer(ARRAY_BUFFER, DYNAMIC_DRAW);\n    /**\n     * @private\n     */\n    this.indicesBuffer_ = new WebGLArrayBuffer(\n      ELEMENT_ARRAY_BUFFER,\n      DYNAMIC_DRAW,\n    );\n\n    /**\n     * @private\n     */\n    this.vertexShader_ = options.vertexShader;\n\n    /**\n     * @private\n     */\n    this.fragmentShader_ = options.fragmentShader;\n\n    /**\n     * @type {WebGLProgram}\n     * @private\n     */\n    this.program_;\n\n    /**\n     * @type {boolean}\n     * @private\n     */\n    this.hitDetectionEnabled_ = options.hitDetectionEnabled ?? true;\n\n    const customAttributes = options.attributes\n      ? options.attributes.map(function (attribute) {\n          return {\n            name: 'a_' + attribute.name,\n            size: 1,\n            type: AttributeType.FLOAT,\n          };\n        })\n      : [];\n\n    /**\n     * A list of attributes used by the renderer.

At rendering time, the layers\n * will be ordered, first by Z-index and then by position. When `undefined`, a `zIndex` of 0 is assumed\n * for layers that are added to the map's `layers` collection, or `Infinity` when the layer's `setMap()`\n * method was used.\n * @property {number} [minResolution] The minimum resolution (inclusive) at which this layer will be\n * visible.\n * @property {number} [maxResolution] The maximum resolution (exclusive) below which this layer will\n * be visible.\n * @property {number} [minZoom] The minimum view zoom level (exclusive) above which this layer will be\n * visible.\n * @property {number} [maxZoom] The maximum view zoom level (inclusive) at which this layer will\n * be visible.\n * @property {import(\"../render.js\").OrderFunction} [renderOrder] Render order. Function to be used when sorting\n * features before rendering. By default features are drawn in the order that they are created. Use\n * `null` to avoid the sort, but get an undefined draw order.\n * @property {number} [renderBuffer=100] The buffer in pixels around the tile extent used by the\n * renderer when getting features from the vector tile for the rendering or hit-detection.\n * Recommended value: Vector tiles are usually generated with a buffer, so this value should match\n * the largest possible buffer of the used tiles. It should be at least the size of the largest\n * point symbol or line width.\n * @property {VectorTileRenderType} [renderMode='hybrid'] Render mode for vector tiles:\n *  `'hybrid'`: Polygon and line elements are rendered as images, so pixels are scaled during zoom\n *    animations. Point symbols and texts are accurately rendered as vectors and can stay upright on\n *    rotated views, but get lifted above all polygon and line elements.\n *  `'vector'`: Everything is rendered as vectors and the original render order is maintained. Use\n *    this mode for improved performance and visual epxerience on vector tile layers with not too many\n *    rendered features (e.g. for highlighting a subset of features of another layer with the same\n *    source).\n * @property {VectorTileSourceType} [source] Source.\n * @property {import(\"../Map.js\").default} [map] Sets the layer as overlay on a map. The map will not manage\n * this layer in its layers collection, and the layer will be rendered on top. This is useful for\n * temporary layers. The standard way to add a layer to a map and have it managed by the map is to\n * use [map.addLayer()]{@link import(\"../Map.js\").default#addLayer}.\n * @property {boolean|string|number} [declutter=false] Declutter images and text. Any truthy value will enable\n * decluttering. Within a layer, a feature rendered before another has higher priority. All layers with the\n * same `declutter` value will be decluttered together. The priority is determined by the drawing order of the\n * layers with the same `declutter` value. Higher in the layer stack means higher priority. To declutter distinct\n * layers or groups of layers separately, use different truthy values for `declutter`.\n * @property {import(\"../style/Style.js\").StyleLike|import(\"../style/flat.js\").FlatStyleLike|null} [style] Layer\n * style. When set to `null`, only\n * features that have their own style will be rendered. See {@link module:ol/style/Style~Style} for the default style\n * which will be used if this is not set.\n * @property {import(\"./Base.js\").BackgroundColor} [background] Background color for the layer. If not specified, no\n * background will be rendered.\n * @property {boolean} [updateWhileAnimating=false] When set to `true`, feature batches will be\n * recreated during animations. This means that no vectors will be shown clipped, but the setting\n * will have a performance impact for large amounts of vector data. When set to `false`, batches\n * will be recreated when no animation is active.\n * @property {boolean} [updateWhileInteracting=false] When set to `true`, feature batches will be\n * recreated during interactions. See also `updateWhileAnimating`.\n * @property {number} [preload=0] Preload. Load low-resolution tiles up to `preload` levels. `0`\n * means no preloading.\n * @property {boolean} [useInterimTilesOnError=true] Deprecated.  Use interim tiles on error.\n * @property {Object<string, *>} [properties] Arbitrary observable properties. Can be accessed with `#get()` and `#set()`.\n * @property {number} [cacheSize=0] The internal tile cache size.

+<#
+.SYNOPSIS
+    Creates or updates GitHub Actions Azure OIDC and staging UI test configuration.
+
+.DESCRIPTION
+    This script prepares a SimpleChat repository for a protected staging GitHub Actions
+    workflow. It creates an Entra app registration and service principal for GitHub
+    OIDC, adds a federated credential for a GitHub Environment, optionally grants
+    Azure RBAC for azd up/deploy, optionally assigns a UI test principal to the
+    SimpleChat Enterprise App, and writes the required GitHub Environment variables
+    and secrets when the GitHub CLI is installed and authenticated.
+
+.PARAMETER GitHubRepository
+    GitHub repository in owner/name format. If omitted, the script attempts to read
+    the origin remote from the current git repository.
+
+.PARAMETER GitHubEnvironment
+    GitHub Environment name. Defaults to Staging.
+
+.PARAMETER AzdEnvironmentName
+    Azure Developer CLI environment name. Defaults to staging.
+
+.PARAMETER AppName
+    SimpleChat deployment app name. Defaults to simplechat.
+
+.PARAMETER AzureLocation
+    Azure location for azd environment creation or workflow fallback variables.
+    If omitted, the current azd environment value or Azure CLI default is used.
+
+.PARAMETER CiAppRegistrationName
+    Display name for the GitHub Actions OIDC app registration. Defaults to
+    "<AppName>-<AzdEnvironmentName>-github-actions".
+
+.PARAMETER RoleAssignmentScope
+    Azure RBAC scope for the GitHub Actions service principal. Defaults to the
+    current subscription because the SimpleChat Bicep entrypoint is subscription-scoped.
+    Use a resource group scope for deploy-only workflows against existing infrastructure.
+
+.PARAMETER PlaywrightWorkspaceName
+    Optional Microsoft Playwright Workspaces resource name. Defaults to
+    "<AppName>-<AzdEnvironmentName>-pw".
+
+.PARAMETER PlaywrightWorkspaceLocation
+    Azure region for the Playwright workspace. Playwright Workspaces currently
+    supports a smaller region set than App Service; defaults to eastus.
+
+.PARAMETER PlaywrightWorkspaceResourceGroupName
+    Optional resource group for the Playwright workspace. Defaults to
+    "<AppName>-<AzdEnvironmentName>-rg" so it lives beside the staging app.
+
+.PARAMETER SkipPlaywrightWorkspace
+    Do not create or configure Microsoft Playwright Workspaces.
+
+.PARAMETER AppServiceResourceGroupName
+    Optional App Service resource group name used when enabling CI bearer session auth.
+    Defaults to the azd var_rgName output or "<AppName>-<AzdEnvironmentName>-rg".
+
+.PARAMETER AppServiceName
+    Optional App Service name used when enabling CI bearer session auth. Defaults to
+    the azd var_webService output or "<AppName>-<AzdEnvironmentName>-app".
+
+.PARAMETER SkipCiBearerSessionAuth
+    Do not configure the staging app to accept GitHub Actions app-only bearer
+    tokens through the guarded /ci-auth/session endpoint.
+
+.PARAMETER SkipRoleAssignments
+    Do not create Azure role assignments for the GitHub Actions service principal.
+
+.PARAMETER SkipGitHubConfiguration
+    Do not write GitHub Environment variables or secrets.
+
+.PARAMETER ForceFederatedCredentialUpdate
+    Recreate the GitHub OIDC federated credential if it already exists.
+
+.PARAMETER AzdEnvironmentValuesPath
+    Optional path to an azd .env file to store in GitHub as AZD_ENV_FILE_B64. If not
+    supplied, the script runs `azd env get-values -e <AzdEnvironmentName>`.
+
+.PARAMETER UiStorageStatePath
+    Optional Playwright storage_state JSON file for a signed-in staging user.
+
+.PARAMETER AdminUiStorageStatePath
+    Optional Playwright storage_state JSON file for a signed-in staging admin.
+
+.PARAMETER SimpleChatUiBaseUrl
+    Optional staging base URL. Defaults to the standard App Service hostname for
+    <AppName>-<AzdEnvironmentName>-app in the current Azure cloud.
+
+.PARAMETER EnterpriseAppClientId
+    Optional SimpleChat Enterprise App client ID. When supplied with UiTestPrincipalObjectId,
+    the script assigns the principal to the requested app role using Microsoft Graph.
+
+.PARAMETER UiTestPrincipalObjectId
+    Optional Entra user or group object ID for the UI test browser identity.
+
+.PARAMETER UiTestAppRoleValue
+    SimpleChat app role value to assign to UiTestPrincipalObjectId. Defaults to User.
+
+.EXAMPLE
+    .\Initialize-GitHubActionsStaging.ps1 -GitHubRepository microsoft/simplechat -AzdEnvironmentName staging -AppName simplechat -UiStorageStatePath .\ui-storage-state.json
+
+.EXAMPLE
+    .\Initialize-GitHubActionsStaging.ps1 -SkipGitHubConfiguration
+
+.NOTES
+    - Requires Azure CLI and Azure Developer CLI.
+    - GitHub secret/variable writes require GitHub CLI (`gh`) and `gh auth login`.
+    - The workflow uses OIDC, so no Azure client secret is stored in GitHub.

+## Default capacity choices
+
+The Azure CLI deployer defaults to Azure AI Search Standard S1 with standard Semantic Ranker and Cosmos DB provisioned throughput using dedicated autoscale throughput on each SimpleChat container. These defaults are intended for reliable workspace search, document upload processing, and semantic retrieval after deployment while avoiding the 25-container limit for shared-throughput Cosmos databases.
+
+For a short-lived MVP or evaluation environment, you can edit the variables near the top of [deploy-simplechat.ps1](deploy-simplechat.ps1) to use `Serverless` Cosmos DB or `free` Azure AI Search/Semantic Ranker. Those settings are intentionally opt-in because Free Search and serverless Cosmos DB have limits that can surface as search, indexing, or quota problems under real usage.
+
+## Code-only upgrade flow
+
+For an existing Azure CLI deployment where infrastructure is unchanged, use `upgrade-simplechat.ps1` instead of rerunning the full deployer.
+
+This script:
+
+- builds the requested image tag in ACR with `az acr build`
+- updates the existing App Service container image with `az webapp config container set`
+- verifies the App Service now points to the requested image
+- restarts the web app so the new image is pulled
+
+Example with explicit resource names:
+
+```powershell
+cd deployers/azurecli
+./upgrade-simplechat.ps1 `
+	-AcrName registrysimplechatprod `
+	-ImageName simplechat:2026-04-29_01 `
+	-ResourceGroupName sc-contoso-prod-rg `
+	-WebAppName contoso-prod-app
+```
+
+Example using the same base-name and environment naming convention as `deploy-simplechat.ps1`:
+
+```powershell
+cd deployers/azurecli
+./upgrade-simplechat.ps1 `
+	-AcrName registrysimplechatprod `
+	-ImageName simplechat:2026-04-29_01 `
+	-BaseName contoso `
+	-Environment prod
+```
+
+This flow is the Azure CLI deployer's PowerShell-first equivalent to a normal container-only `azd deploy`, without invoking the AZD post-configuration Python path.
+
+If the image already exists in ACR and you only want App Service to move to that tag, add `-SkipAcrBuild`.

+<#
+.SYNOPSIS
+    Performs a code-only SimpleChat container upgrade for the Azure CLI deployer.
+.DESCRIPTION
+    This PowerShell script builds a new container image in Azure Container Registry
+    using ACR Tasks and updates an existing Azure App Service to pull that image.
+
+    This is the Azure CLI deployer equivalent of an `azd deploy` style code-only
+    rollout. It does not provision or change infrastructure resources beyond the
+    target web app's container configuration.
+
+    The script supports either:
+        - explicit targeting with -ResourceGroupName and -WebAppName
+        - derived targeting with -BaseName and -Environment to match deploy-simplechat.ps1
+
+    The deployment model remains a container-based Azure App Service. Gunicorn
+    startup continues to come from the container entrypoint.
+
+.NOTES
+    Author: Microsoft Federal
+    Date: 2026-04-29
+    Version: 1.0
+
+    Prerequisites:
+        - Azure CLI installed and authenticated.
+        - Access to the target subscription, ACR, and App Service.
+        - The target ACR already exists.
+        - The target web app already exists and is configured for the SimpleChat container path.

 `imageName` defaults to `simplechat:latest`. Most deployments can accept that default without entering a custom value.
 
+When `authenticationType` is `managed_identity`, the AZD preprovision hook validates that the current Azure identity can create the role assignments and custom role definitions needed by the deployment. If the identity does not have Owner, Role Based Access Control Administrator, or an equivalent custom role at the target scopes, deployment stops before provisioning continues. You can rerun with an identity that has the required permissions, ask an Azure administrator to complete the RBAC setup, or switch the AZD environment to key-based authentication with `azd env set AUTHENTICATION_TYPE key` if that security model is acceptable.

 `openAIDeploymentType` controls the default Azure OpenAI model deployment type used when this deployment creates the GPT and embedding model deployments for you.

 **Q: What is the default authentication type?**
 A: You can choose between `key` (API keys stored in Key Vault) or `managed_identity` (recommended for production).
 
+**Q: Why does managed identity deployment stop before provisioning?**
+A: Managed identity deployment must create RBAC role assignments for the App Service identity and related resources. If the signed-in Azure identity cannot perform `Microsoft.Authorization/roleAssignments/write` and `Microsoft.Authorization/roleDefinitions/write` at the target scopes, the preprovision hook fails fast instead of letting deployment appear successful while runtime access is broken. Use Owner, Role Based Access Control Administrator, or an equivalent custom role, then rerun `azd up`. To continue with key-based authentication instead, run `azd env set AUTHENTICATION_TYPE key` and rerun the deployment.
+
+**Q: What capacity defaults does the deployer use?**
+A: The Bicep and AZD path defaults to Azure AI Search Standard S1 with standard Semantic Ranker and Cosmos DB provisioned autoscale throughput on each SimpleChat container. These defaults avoid the limited free semantic query quota, avoid the 25-container limit for shared-throughput databases, and make document search and ingestion more reliable after first deployment.
+
+**Q: Can I use Free Search or serverless Cosmos DB for an MVP?**
+A: Yes, but treat those as short-lived MVP or evaluation settings. Set `searchSkuName` and `searchSemanticSearchSku` to `free`, or set `cosmosCapacityMode` to `serverless`, only when you understand the service limits and do not need production-grade document search throughput. The repository defaults remain Standard S1 Search and provisioned Cosmos DB.

+Terraform defaults to Azure AI Search Standard S1 with standard Semantic Ranker and Cosmos DB provisioned dedicated container autoscale throughput. Free Search and serverless Cosmos DB remain configurable for short-lived MVP phases, but they are not the repository defaults because they can hit semantic query, indexing, or request-unit limits during document-heavy testing.
+
 ## Deploy initial container
 
 Terraform does not build the container image itself. It expects `image_name` to point to an image tag that already exists in your Azure Container Registry.

+## Admin Settings Execution Guide
+
+Use this section when you need to configure an area, validate it, and know what to check after saving. Open **Admin Settings**, select the named tab, make the change, use the local test buttons where the tab provides them, then click **Save Settings**.
+
+### General
+
+![Annotated General settings controls](./images/admin-settings/general.png)
+
+1. Open **General** and set the app title, light/dark logos, favicon, home page Markdown, default theme, and default navigation layout.
+2. Configure operational visibility: authenticated and unauthenticated health checks, Swagger/OpenAPI, classification banner, Support menu, Latest Features visibility, and external links.
+3. Set global system behavior such as file size limits, conversation history, and the default system prompt, then save and refresh the home page to confirm branding and navigation changes.
+
+### AI Models
+
+![Annotated AI model controls](./images/admin-settings/ai-models.png)
+
+1. Open **AI Models** and add the chat model endpoint configuration: direct Azure OpenAI, Foundry (classic), New Foundry, or APIM endpoint, authentication type, deployment names, and any default model choices. For managed identity or service principal RBAC setup, see [Configure Model Endpoint Identity]({{ '/how-to/model_endpoint_identity_setup/' | relative_url }}).
+2. Configure **Embeddings** before enabling retrieval-backed workspace features, then use the connection test to verify the endpoint and authentication path.
+3. Enable **Processing Thoughts** and **Image Generation** only for deployments where users should see reasoning traces or generate images, then save and confirm the model selector appears in chat.
+
+### Agents And Actions
+
+![Annotated Agents and actions controls](./images/admin-settings/agents-actions.png)
+
+1. Open **Agents and Actions** and choose whether document actions such as Analyze and Document Comparison should appear in Chat and Workflow action menus.
+2. Enable agents, choose workspace-specific or global mode, set orchestration behavior, and manage global agents or approvals if admins curate shared agents centrally.
+3. Enable action scopes and core plugins users are allowed to invoke. Save global agent/action changes, restart the web app when the tab notes it is required, and then verify the runtime action menus.
+
+### Logging
+
+![Annotated Logging controls](./images/admin-settings/logging.png)
+
+1. Open **Logging** and enable Application Insights logging when agent, orchestration, or operational events should flow into Azure monitoring.
+2. Use **Debug Logging** for short diagnosis windows only, set an auto-disable time, and avoid leaving token or key capture enabled longer than necessary.
+3. Enable **File Processing Logs** when admins need upload, extraction, indexing, or sync troubleshooting history, then save and confirm the expected log container or telemetry stream receives events.
+
+### Scale
+
+![Annotated Scale controls](./images/admin-settings/scale.png)
+
+1. Open **Scale** and configure Redis when the app will run multiple instances or needs distributed session storage; test the Redis connection before saving.
+2. Use the Cosmos throughput card to refresh status, choose database or container scope, set autoscale thresholds, enforce global policy when appropriate, and convert eligible manual throughput to native autoscale.
+3. Configure Azure Front Door when authentication redirects and user-facing URLs should use the routed domain, then save and validate sign-in through the Front Door URL.
+
+### Control Center
+
+![Annotated Control Center controls](./images/admin-settings/control-center.png)
+
+1. Open **Control Center** and set the auto-refresh interval used by dashboard and management views.
+2. Choose which overview behavior should be available to admins, especially in larger deployments where refresh frequency affects load.
+3. Save the settings, open Control Center, and confirm the dashboard refresh cadence and management tables behave as configured.
+
+### Workspaces
+
+![Annotated Workspace controls](./images/admin-settings/workspaces.png)
+
+1. Open **Workspaces** and enable the workspace types your users should see: personal, group, public, workflow, and file sharing options.
+2. Configure upload behavior, chat file uploads, metadata extraction, multimodal vision, document classification, and any group or public workspace role requirements.
+3. Set retention policies, workspace scope lock, and user agreement text, then save and verify the corresponding workspace navigation and upload actions with a normal user account.
+
+### File Sync
+
+![Annotated File Sync controls](./images/admin-settings/file-sync.png)
+
+1. Open **File Sync** and enable the connector, visible source types, and the workspace scopes where synced files may appear.
+2. Configure personal, group, and public workspace sync behavior before creating sources so each source lands in the correct ownership model.
+3. Use **Manage File Sync Sources** and **File Sync App Role Setup** to create source definitions and app roles, then run a sync and verify badges, history, and imported documents.
+
+### Global Identity
+
+![Annotated global identity controls](./images/admin-settings/global-identity.png)
+
+1. Open **Workspace Identities** to review reusable identities that File Sync and workspace connectors can share across sources.
+2. Create or update identity mappings when multiple sync sources should use the same managed identity, app registration, or delegated access profile.
+3. Save the identity configuration, return to File Sync, and assign the identity to a source before running the connector test or sync job.
+
+### Citations
+
+![Annotated Citation controls](./images/admin-settings/citation.png)
+
+1. Open **Citations** and enable enhanced citations when users need direct file preview, source documents, or richer citation playback.
+2. Configure Azure Storage using either connection string or managed identity endpoint, then test access before saving.
+3. Upload or reprocess a document after saving and confirm chat citations can open the expected preview or source reference.
+
+### Safety
+
+![Annotated Safety controls](./images/admin-settings/safety.png)
+
+1. Open **Safety** and configure Azure Content Safety endpoint routing, authentication, and connection testing before enabling filtering for users.
+2. Enable user feedback, safety violation admin role enforcement, and feedback admin role enforcement according to your review process.
+3. Configure conversation archiving versus deletion, save, and verify that feedback and safety review pages respect the selected RBAC controls.
+
+### Security
+
+![Annotated Security controls](./images/admin-settings/security.png)
+
+1. Open **Security** and review any role-gated or secret-management settings that control access to sensitive admin tools.
+2. Enable required app roles before turning on enforcement, then assign those roles in Entra ID to the admin groups that need access.
+3. Save and validate with both an authorized admin and a normal user so restricted views remain reachable only to the intended audience.
+
+### Search And Extract
+
+![Annotated Search and Extract controls](./images/admin-settings/search-extract.png)
+
+1. Open **Search and Extract** and configure Web Search, URL Access, and Deep Research only for deployments where admins have approved outbound source review behavior.
+2. Configure Azure AI Search and Document Intelligence endpoints, select Read, Layout, or Auto extraction mode, and test each connection.
+3. Set chunk sizes and multimedia extraction services such as Video Indexer and Speech, then upload a document or media file to confirm extraction, indexing, and citation behavior.
+
+### Send Feedback
+
+![Annotated Send Feedback controls](./images/admin-settings/send-feedback.png)
+
+1. Open **Send Feedback** from Admin Settings or the Support menu after the Support destination is enabled in General.
+2. Enter the issue, enhancement request, or operational context with enough detail for admins to reproduce or triage it.
+3. Submit the feedback and confirm it arrives through the configured support recipient or review workflow.

 ## Navigation Options
 
 The Admin Settings page supports two navigation layouts:
@@ -240,6 +363,7 @@ The Admin Settings page supports two navigation layouts:
 - **APIM vs Direct**: When using Azure API Management (APIM), you'll need to manually specify model names as automatic model fetching is not available
 - **Managed Identity**: When using Managed Identity authentication, ensure your Service Principal has the appropriate roles assigned:
   - **Azure OpenAI**: Cognitive Services OpenAI User role
+  - **Model Endpoints**: Azure OpenAI multi-endpoint discovery also needs Reader on the Azure OpenAI resource. Foundry (classic) and New Foundry endpoints need Foundry User, or Azure AI User where older role names are still shown, on the target project or backing Foundry resource. See [Configure Model Endpoint Identity]({{ '/how-to/model_endpoint_identity_setup/' | relative_url }}).
   - **Speech Service**: Start with `Cognitive Services Speech User`; add `Cognitive Services Speech Contributor` if transcription operations still require it. Managed identity also requires the custom-domain Speech endpoint, and text-to-speech needs the Speech Resource ID.
   - **Video Indexer**: Grant the App Service system-assigned managed identity `Contributor` on the Video Indexer resource. If Azure asks for a user-assigned managed identity during Video Indexer resource creation, that identity is for the Video Indexer resource itself, not for Simple Chat runtime calls.
 - **Dependencies**: The walkthrough will alert you if required services aren't configured when you enable dependent features (e.g., workspaces require embeddings, AI Search, and Document Intelligence)

+# Admin Source Test Tools
+
+Implemented in version: **0.241.094**
+
+## Overview
+
+Admin Source Test Tools add lightweight verification controls to Admin Settings for governed external source features:
+
+- Web Search Foundry Agent smoke testing from the Search & Extract settings tab.
+- URL Access allowed and blocked domain policy testing from the same tab.
+
+The application version was updated in `application/single_app/config.py` to `0.241.094` for this feature.
+
+## Technical Specifications
+
+### Architecture
+
+- The Web Search modal calls the existing `/api/admin/settings/test_connection` route with `test_type: web_search` and the current unsaved Foundry form values.
+- The URL Policy modal calls the same admin-only route with `test_type: url_access_policy` and the current unsaved URL Access domain rules.
+- URL policy evaluation uses Source Review URL normalization and safety validation without fetching remote content.
+- Browser-facing result rendering uses static Bootstrap modal shells and JavaScript DOM APIs with `textContent` for returned messages, details, and guidance.
+
+### API Endpoints
+
+- `POST /api/admin/settings/test_connection`
+  - `test_type: web_search` runs the configured Foundry agent against a short admin test prompt.
+  - `test_type: url_access_policy` evaluates one URL against URL Access policy and SSRF safety validation.
+
+### Configuration Options
+
+- Web Search: `enable_web_search`, `web_search_consent_accepted`, and `web_search_agent.other_settings.azure_ai_foundry` fields.
+- URL Access: `enable_url_access`, `url_access_allowed_domains`, `url_access_blocked_domains`, and `source_review_allow_internal_hosts`.
+
+### File Structure
+
+- `application/single_app/functions_url_access_policy_test.py`
+- `application/single_app/functions_web_search_test.py`
+- `application/single_app/functions_source_review.py`
+- `application/single_app/route_backend_settings.py`
+- `application/single_app/templates/admin_settings.html`
+- `application/single_app/static/js/admin/admin_settings.js`
+- `functional_tests/test_url_access_admin_policy_test.py`
+- `functional_tests/test_web_search_admin_connection_test.py`
+- `ui_tests/test_admin_source_review_settings.py`
+
+## Usage Instructions
+
+1. Open Admin Settings and select Search & Extract.
+2. Enable Web Search and configure the Azure AI Foundry agent settings.
+3. Select **Test Web Search** to open the smoke-test modal and run the configured agent.
+4. Configure URL Access allowed or blocked domains.
+5. Select **Test URL Policy**, enter a URL, and run the policy test to see whether URL Access would allow or block it.
+
+## Testing and Validation
+
+- Functional tests validate Web Search custom prompts and URL Access policy outcomes.
+- UI coverage validates modal visibility, test result rendering, and allowed/blocked URL policy states.
+- The URL policy test does not fetch remote content; it validates normalization, domain policy, and server-side URL safety gates.

+# Blob-Backed Chat Image Storage
+
+## Overview
+
+Enhanced-citation chat images are stored as blob-backed chat artifacts instead of embedding image bytes directly in Cosmos DB message content. Chat rendering continues to use authenticated image routes, so streaming and non-streaming responses receive a lightweight `/api/image/<message_id>` URL.
+
+Version implemented: **0.241.032**
+
+Implemented in version: **0.241.032**
+
+Related config.py version update: `application/single_app/config.py` was incremented to `0.241.032`.
+
+## Dependencies
+
+- Azure Blob Storage chat containers: `personal-chat` and existing group chat container configuration.
+- Enhanced citations setting: `enable_enhanced_citations`.
+- Existing authenticated image endpoints for personal and collaborative conversations.
+
+## Technical Specifications
+
+### Architecture
+
+- Uploaded and generated images use blob-backed message metadata when enhanced citations are enabled.
+- Message records keep `file_content_source`, `blob_container`, `blob_path`, `mime_type`, and a lightweight authenticated route in `content`.
+- Legacy inline and chunked Cosmos image storage remains available when enhanced citations are disabled or for older messages.
+- Blob-backed image files are compatible with existing blob-backed message deletion workflows.
+
+### API Endpoints
+
+- `GET /api/image/<message_id>` streams personal or collaboration-visible blob-backed source images after conversation authorization.
+- `GET /api/collaboration/conversations/<conversation_id>/images/<message_id>` streams blob-backed source images for authorized collaboration viewers.
+
+### File Structure
+
+- `application/single_app/functions_image_messages.py`
+- `application/single_app/functions_simplechat_operations.py`
+- `application/single_app/route_frontend_chats.py`
+- `application/single_app/route_backend_chats.py`
+- `application/single_app/route_backend_conversations.py`
+- `application/single_app/route_backend_collaboration.py`
+
+## Usage Instructions
+
+No new user configuration is required beyond enabling enhanced citations. Images uploaded to chat or generated by image-capable models render through the same chat UI image flow, but the stored message content remains small.
+
+## Testing and Validation
+
+Functional coverage: `functional_tests/test_chunked_image_storage.py` validates blob-backed image hydration alongside existing chunked image behavior.
+
+Performance consideration: image bytes stream from Blob Storage instead of expanding Cosmos message payloads, reducing message item size and avoiding the Cosmos item-size pressure that large base64 images create.
+
+Known limitation: existing legacy image messages remain in their original inline or chunked shape until they are naturally removed by existing retention or deletion workflows.

+# Broken Access Control Full-Repo Audit Guardrails
+
+Implemented in version: **0.241.203**
+
+Fixed/Implemented in version: **0.241.203**
+
+## Overview
+
+This feature adds reusable guardrails for Broken Access Control, IDOR, and BOLA-style reviews beyond a single endpoint fix. It provides a manually runnable GitHub Actions workflow for full-code audits, expands the repository instruction set for future Python development, and adds a workspace prompt that agents can use to perform focused authorization reviews.
+
+## Purpose
+
+The guardrails help prevent new development from trusting caller-supplied object IDs after login. They are especially targeted at reverse-resolution and object-lookup endpoints that turn known user IDs, conversation IDs, document IDs, group IDs, or workspace IDs into protected metadata without proving that the caller can access the exact target object.
+
+## Dependencies
+
+- `.github/workflows/broken-access-control-full-scan.yml`
+- `.github/instructions/broken-access-control-prevention.instructions.md`
+- `.github/prompts/broken-access-control-audit.prompt.md`
+- `scripts/check_broken_access_control.py`
+- `functional_tests/test_broken_access_control_guardrails_checker.py`
+
+## Technical Specifications
+
+### Manual Full Scan Workflow
+
+`.github/workflows/broken-access-control-full-scan.yml` defines a `workflow_dispatch` audit workflow with inputs for target paths, strictness, and self-test execution. It collects tracked Python files under the selected paths, runs `scripts/check_broken_access_control.py --full-file`, uploads a report artifact, and defaults to advisory mode so existing legacy findings can be reviewed without immediately failing the run.
+
+### Repository Instruction
+
+The Broken Access Control instruction now explicitly covers caller-controlled user IDs, Entra object IDs, owner IDs, participant IDs, shared user IDs, route path IDs, request body IDs, query-string IDs, plugin IDs, and datastore-sourced IDs. It also documents acceptable cross-user profile display relationships and calls out role-only decorators, GUID opacity, Graph lookup access, and frontend reachability as insufficient object authorization.
+
+### Workspace Prompt
+
+`.github/prompts/broken-access-control-audit.prompt.md` is a reusable Copilot prompt for agent-assisted audits. It guides the reviewer to trace object IDs from source to sink, distinguish role checks from object checks, identify oracle behavior, and produce findings with source, sink, missing check, impact, remediation, and regression-test details.
+
+## Usage Instructions
+
+Run the full-code audit from GitHub Actions:
+
+1. Open Actions.
+2. Select `Broken Access Control Full Scan`.
+3. Choose target paths, such as `application scripts`.
+4. Leave `fail_on_findings` as `false` for baseline/advisory runs.
+5. Download the `broken-access-control-full-scan-report` artifact and triage findings.
+
+Run a strict audit after the current baseline is clean:
+
+```text
+fail_on_findings=true
+```
+
+Run the agent-assisted prompt from VS Code Chat by selecting `Broken Access Control Audit` and providing paths, a feature area, or an incident class.
+
+## Testing and Validation
+
+Test coverage verifies that the BAC checker catches direct user-profile document reads, allows approved helper-based patterns, and that the workflow, instruction, prompt, and feature documentation remain wired into the repository.
+
+Known limitation: the full scan currently reports legacy findings when run across all tracked Python files. The workflow therefore defaults to advisory mode until those findings are triaged, fixed, or marked with reviewed suppressions.

+# Chat Backend Inline Chart Handoff
+
+Implemented in version: **0.241.124**
+
+Last validated with config.py version: **0.241.126**
+
+## Overview
+
+Normal chat conversations can now participate in the same inline chart rendering flow used by chart-enabled agents. Explicit chart requests receive backend chart guidance, can fall back through the core conversation chart plugin when Semantic Kernel is available, and preserve any returned `simplechart` blocks in the streamed and saved assistant message.
+
+## Dependencies
+
+- `application/single_app/route_backend_chats.py`
+- `application/single_app/functions_chart_operations.py`
+- `application/single_app/semantic_kernel_plugins/chart_plugin.py`
+- `application/single_app/static/js/chat/chat-inline-charts.js`
+- `application/single_app/config.py` version `0.241.126`
+
+## Technical Specifications
+
+### Architecture Overview
+
+The chat route already renders inline chart markdown through the frontend `simplechart` fence parser. This update extends the backend handoff so model-only chat requests get chart guidance before raw GPT fallback, and explicit chart requests can use the kernel-native conversation chart plugin even when no agent is selected.
+
+### Backend Flow
+
+1. The chat route detects explicit chart visualization requests and analytical prompts.
+2. Chart guidance is inserted into the system-message prefix before final generation.
+3. For explicit chart requests with a Semantic Kernel chat service, the core `conversation_charts` plugin can be auto-invoked without requiring an agent selection.
+4. Kernel/plugin invocation results are converted into the same citation payload shape used by agent tools.
+5. Returned chart markdown is appended to assistant content when the model did not already place it inline.
+6. Streaming responses emit any backend-appended chart markdown as a final content delta before the `done` event, so the live message and persisted message render the same chart.
+
+### Rendering Behavior
+
+The frontend remains responsible for parsing and hydrating charts. `chat-messages.js` extracts `simplechart` fences before markdown rendering, sanitizes the surrounding HTML, injects chart placeholders, and hydrates them with local Chart.js. `chat-streaming.js` uses the same renderer for live updates and final message replacement.
+
+## Usage Instructions
+
+Users can ask normal chat questions such as "Create a bar chart of revenue by month" or "Include a chart and table for this comparison." When the response includes a valid `simplechart` block, the chat UI renders it inline and preserves it after the stream finishes.
+
+## Testing and Validation
+
+Functional coverage:
+
+- `functional_tests/test_chat_backend_inline_chart_handoff.py`
+
+Validation focus:
+
+- chart guidance reaches standard chat fallback paths
+- explicit chart requests can use kernel chart tooling without an agent
+- plugin-returned chart markdown is appended once
+- backend-appended chart markdown streams before final message save
+
+## Known Limitations
+
+Direct raw GPT fallback cannot execute the chart plugin by itself. It receives chart guidance and can emit valid `simplechart` blocks, while plugin-backed generation requires Semantic Kernel and an available chat completion service.

+# Chat File Upload Access Control
+
+## Overview
+
+Chat file uploads can now be enabled or disabled independently from workspace document uploads. Admins can also require the `ChatFileUploadUser` Enterprise App role before users can upload files directly into chat conversations.
+
+Version implemented: **0.241.098**
+
+Implemented in version: **0.241.098**
+
+Related config.py version update: `application/single_app/config.py` was incremented to `0.241.098`.
+
+## Dependencies
+
+- Entra Enterprise App role value: `ChatFileUploadUser`
+- App settings: `enable_chat_file_uploads` and `require_member_of_chat_file_upload_user`
+- Existing chat upload route: `POST /upload`
+- Existing per-user file upload restrictions still apply through `file_upload_required`
+
+## Technical Specifications
+
+### Architecture
+
+- `enable_chat_file_uploads` globally controls new files uploaded directly into chat.
+- `require_member_of_chat_file_upload_user` optionally requires the authenticated session role claim to include `ChatFileUploadUser`.
+- The chat page receives an effective `enable_chat_file_uploads` value after evaluating global enablement and the current user's role claims.
+- The chat template serializes that effective value to `window.appSettings.enable_chat_file_uploads` so selected, pasted, and dropped files use the same client-side gate.
+- The frontend hides the paperclip controls when the effective setting is disabled and guards paste/drag-and-drop upload flows.
+- The backend rejects unauthorized `POST /upload` requests before processing or storing the uploaded file.
+
+### API Endpoints
+
+- `POST /upload` returns `403` when chat file uploads are globally disabled.
+- `POST /upload` returns `403` when the app role requirement is enabled and the current user does not have `ChatFileUploadUser`.
+
+### Configuration Options
+
+- `enable_chat_file_uploads`: Enables or disables new chat file uploads across personal, group, and multi-user chat surfaces.
+- `require_member_of_chat_file_upload_user`: Requires the `ChatFileUploadUser` Enterprise App role when enabled.
+
+### File Structure
+
+- `application/single_app/functions_settings.py`
+- `application/single_app/route_frontend_admin_settings.py`
+- `application/single_app/route_frontend_chats.py`
+- `application/single_app/templates/admin_settings.html`
+- `application/single_app/templates/chats.html`
+- `application/single_app/static/js/chat/chat-input-actions.js`
+- `deployers/azurecli/appRegistrationRoles.json`
+- `deployers/terraform/main.tf`
+
+## Usage Instructions
+
+1. Open Admin Settings.
+2. Open the Workspaces tab.
+3. Use Chat File Uploads to enable or disable new chat uploads.
+4. Optionally turn on Require ChatFileUploadUser App Role.
+5. Assign the `ChatFileUploadUser` Enterprise App role to users or groups that should upload files into chat.
+
+Existing chat attachments remain visible after the feature is disabled. Workspace document uploads, file sync, and generated artifacts remain governed by their own existing controls.
+
+## Testing and Validation
+
+Functional coverage: `functional_tests/test_chat_file_upload_access_control.py` validates settings defaults, admin persistence, backend enforcement, UI gating snippets, deployment role definitions, documentation, and version tracking.
+
+UI coverage: `ui_tests/test_chat_file_upload_access_control.py` validates that the chat toolbar file controls match the effective server-rendered setting for the authenticated test user.
+
+Related fix: `docs/explanation/fixes/CHAT_FILE_UPLOAD_CLIENT_FLAG_FIX.md` documents the client app settings serialization regression fixed in version `0.241.110`.
+
+Known limitation: Users must refresh their sign-in token after role assignment changes before the new `ChatFileUploadUser` claim appears in the session.

+# Chat Upload Collaboration Workspace Sharing
+
+Implemented in version: **0.241.175**
+
+## Overview
+
+Personal multi-user collaborative conversations now keep chat-uploaded files in the uploader's personal workspace and automatically share those workspace-backed documents with accepted collaboration participants. Pending invitees do not receive access until they accept the invitation.
+
+This extends the chat upload personal workspace handoff without creating duplicate workspace copies for every participant. The owner copy remains the source of truth, and SimpleChat manages collaboration-specific share grants on that document.
+
+## Technical Specifications
+
+### Architecture
+
+- The `/upload` route resolves a visible personal collaboration conversation ID to its hidden source conversation before creating the source chat file message.
+- Workspace document metadata records both the hidden source conversation and visible collaboration conversation IDs.
+- The document sharing sync adds approved `shared_user_ids` entries for accepted participants, excluding the owner.
+- Managed grants are tracked in `chat_upload_auto_shared_user_ids` so participants can be revoked when they leave, are removed, or the collaboration is deleted.
+- Search chunk visibility is synchronized after share metadata changes so accepted participants can ask questions against the shared upload from that collaboration.
+
+### API and Data Flow
+
+1. The browser posts the upload with the visible collaboration `conversation_id`.
+2. The backend validates the user can participate in the collaboration.
+3. The backend resolves or creates the hidden collaboration source conversation.
+4. The file is queued as a personal workspace document owned by the uploader.
+5. Accepted participants are added to the document's approved sharing metadata.
+6. The source file message is mirrored into the visible collaboration timeline.
+7. The upload response returns the visible collaboration ID so the client stays in the collaborative chat.
+
+### File Structure
+
+- `application/single_app/route_frontend_chats.py` resolves collaborative uploads and mirrors workspace-backed file messages.
+- `application/single_app/functions_documents.py` manages collaboration document share grants and chunk visibility.
+- `application/single_app/functions_collaboration.py` syncs grants when participants accept, leave, are removed, or the conversation is deleted.
+- `application/single_app/collaboration_models.py` preserves workspace file fields while mirroring messages.
+- `application/single_app/static/js/chat/chat-input-actions.js` reloads collaborative uploads through the collaboration timeline loader.
+- `application/single_app/static/js/chat/chat-collaboration.js` renders mirrored file messages with the existing workspace file card renderer.
+
+## Usage Instructions
+
+Users upload files from the chat input as usual. In a personal collaborative conversation, accepted participants automatically receive access to the workspace-backed file for that collaboration. If a participant accepts an invite later, SimpleChat syncs existing chat-uploaded workspace documents to that newly accepted participant.
+
+If a participant leaves or is removed, SimpleChat removes only the collaboration-managed share grant. The document remains in the owner's personal workspace and continues to follow the workspace document retention policy.
+
+## Testing and Validation
+
+- Functional contract test: `functional_tests/test_chat_upload_collaboration_workspace_sharing.py`
+- Existing handoff regression coverage: `functional_tests/test_chat_upload_personal_workspace_handoff.py`
+
+The collaboration sharing test validates upload resolution, participant authorization, metadata stamping, approved sharing entries, search chunk propagation, membership lifecycle sync, message mirroring, collaboration file rendering, and the `0.241.175` version update.
+
+## Known Limitations
+
+Automatic sharing applies to personal multi-user collaborative conversations. Group collaboration document access continues to use the group workspace and group authorization model.

+# Chat Upload Group Workspace Handoff
+
+Implemented in version: **0.241.176**
+
+## Overview
+
+Chat uploads in group-scoped conversations now use the group workspace document pipeline instead of chat-local file storage. This keeps uploaded files in the group workspace, lets the standard document processor index them, and makes the document easy to reference in follow-up questions.
+
+## Technical Specifications
+
+The upload route resolves a group destination from the current chat scope, validates that the selected group is part of the conversation or effective group scope, and enforces one of the write roles: `Owner`, `Admin`, or `DocumentManager`.
+
+Regular group chats and group multi-user collaboration chats both queue files through `queue_group_workspace_upload_from_temp_file()`. Group collaboration uploads still mirror a workspace-backed file message into the visible collaborative conversation, while the hidden source conversation stores the canonical message.
+
+Duplicate source filenames are isolated with `resolve_unique_group_workspace_file_name()`, using the same suffix pattern as workspace/file-sync duplicate handling. This prevents repeated chat uploads from becoming accidental revisions of an existing group workspace document.
+
+Group uploaded documents are marked with `source_type: chat_upload`, conversation metadata, the selected `chat_upload_group_id`, and a clean `conversations` tag. Conversation IDs stay in metadata rather than becoming folder/tag clutter.
+
+## User Workflow
+
+When a chat is group-scoped and exactly one writable group workspace is available, uploads go directly to that group workspace. When multiple writable group workspaces are in scope, the browser shows a group-only picker. Personal workspace is not offered as a group upload destination.
+
+If the user can chat in a group but lacks a write role, the upload is blocked. If group workspaces are disabled or the file type cannot be processed by the workspace pipeline, the upload fails clearly rather than falling back to chat-local storage.
+
+## Testing and Validation
+
+Functional coverage is provided by `functional_tests/test_chat_upload_group_workspace_handoff.py`.
+
+The test validates:
+
+- Group workspace queue helper and unique group filename resolution.
+- Server-side group target and write-role enforcement.
+- Group search cache invalidation and group metadata stamping.
+- Frontend group destination picker and form payload.
+- Linked group upload lookup for chat search and conversation delete lifecycle.
+
+Related config update: `application/single_app/config.py` was bumped to **0.241.176**.

+# Chat Upload Personal Workspace Handoff
+
+Implementation status: **Implemented**
+
+Documented against version: **0.241.192**
+
+Fixed/Implemented in version: **0.241.174**
+
+Related config.py version update: `application/single_app/config.py` is **0.241.192** for the latest lifecycle fix.
+
+Implemented in version: **0.241.174**
+
+## Overview
+
+Chat uploads create file messages through `POST /upload`. Personal workspace uploads create document metadata and background processing jobs through `POST /api/documents/upload`. The implemented handoff now makes the personal workspace document the source of truth for eligible chat uploads when personal workspaces are enabled.
+
+When the personal workspace is available, a file uploaded from the chat UI becomes a personal workspace document, gets tagged with `conversations`, stores the associated conversation ID in metadata, and appears in chat as a workspace-backed file message. The chat route does not run a second chat-local extraction or save a duplicate copy to the chat storage container for that eligible upload. When the personal workspace is not available, the existing chat-only upload flow continues without behavioral change.
+
+Chat uploads also resolve duplicate personal workspace filenames before document metadata is created. If a user uploads `report.pdf` from multiple chats, the later workspace document gets a collision-free name such as `report (1234).pdf` or `report (1).pdf`, while the original uploaded filename remains in metadata for traceability. This mirrors File Sync's identity-first behavior: File Sync tracks a source item by path-derived identity, while chat uploads track the source by conversation and message identity and keep the workspace filename unique so separate uploads do not collapse into the workspace revision flow.
+
+## Goals
+
+- Preserve the existing chat upload UX: pasted, dropped, and selected files should still appear in the current conversation as uploaded file messages.
+- Automatically make chat-uploaded files available to personal workspace search, document analysis, document comparison, and enhanced citation pipelines.
+- Avoid requiring the user to manually select the personal workspace or re-upload the file after uploading it into chat.
+- Add clear lifecycle behavior for linked documents when the conversation is deleted or the workspace document is deleted first.
+- Keep fallback behavior simple: if the personal workspace path is disabled, use the current chat-only flow; if an eligible workspace handoff fails, surface the failure instead of silently storing the file in chat-local storage.
+- Avoid duplicate chat-local processing and chat storage for uploads that have already been accepted into the personal workspace pipeline.
+- Avoid filename collisions that would turn separate chat uploads into personal workspace document revisions.
+
+## Dependencies
+
+- App settings: `enable_chat_file_uploads`, `require_member_of_chat_file_upload_user`, `enable_user_workspace`, `enable_enhanced_citations`, and `enable_conversation_archiving`.
+- Existing chat upload route: `POST /upload`.
+- Existing personal workspace upload route: `POST /api/documents/upload`.
+- Existing personal workspace delete route: `DELETE /api/documents/<document_id>`.
+- Existing conversation delete routes: `DELETE /api/conversations/<conversation_id>` and `POST /api/delete_multiple_conversations`.
+- Existing document tag storage and propagation through `functions_documents.py`.
+- Existing chat conversation deep-link support through `/chats?conversation_id=<conversation_id>`.
+
+## Expected User Workflow
+
+1. A user uploads, drops, or pastes a file in the chat UI.
+2. If the personal workspace is enabled and the file type is eligible, the file is queued as a personal workspace document.
+3. The chat conversation shows a workspace-backed upload message with the processing progress bar visible; the uploaded file name links to the workspace document.
+4. Users can expand the progress card to see status text while processing, and status details collapse by default again when processing finishes.
+5. After processing completes, the Workspaces panel is activated and the completed document is selected in the document picker.
+6. Questions in that conversation automatically include the linked workspace document in the workspace search/enhanced citation context.
+7. The workspace document can be searched, analyzed, compared, cited, edited, tagged, or deleted through normal workspace flows.
+8. The workspace document shows enough linkage metadata for the user to understand it came from a chat conversation.
+9. If the user deletes the workspace document first, the delete modal warns that the document is associated with a conversation and links back to it.
+10. If the user deletes the conversation first, linked workspace documents are listed in the delete dialog and only the documents the user selects are deleted with the conversation.
+
+## Current Behavior
+
+### Chat Uploads
+
+`application/single_app/route_frontend_chats.py` registers `POST /upload`. The route currently:
+
+- Enforces `enable_chat_file_uploads`, optional `ChatFileUploadUser`, login, user access, and `file_upload_required`.
+- Creates a new personal conversation if no `conversation_id` is submitted.
+- Saves the file to a temporary path and queues eligible files into personal workspace processing.
+- Resolves a collision-free personal workspace filename before queuing eligible chat uploads.
+- Creates a workspace-backed `role = file` chat message for successful workspace handoff and skips duplicate chat-local extraction/blob storage.
+- Polls the personal workspace document status from the chat message and from the upload response's `workspace_document_id` so active chat cards update without a browser refresh.
+- Keeps the progress bar visible while processing and collapses status text behind an expand control for in-progress and completed states.
+- Activates the Workspaces panel and selects the completed personal workspace document in the document picker so the user can keep the default Search action or choose Analyze/Compare.
+- Syncs final status back into chat message metadata so reloads do not show stale queued progress.
+- Uses the existing chat-only extraction and blob-backed paths only when workspace handoff is not eligible because personal workspace is unavailable.
+- Returns a workspace upload failure if an eligible personal workspace handoff cannot be queued.
+- Updates conversation `last_updated` and may derive the conversation title from the uploaded filename.
+- Returns the existing response shape expected by `static/js/chat/chat-input-actions.js`: `conversation_id` and optional `title`.
+
+### Personal Workspace Uploads
+
+`application/single_app/route_backend_documents.py` registers `POST /api/documents/upload`. The route currently:
+
+- Requires `enable_user_workspace` and `file_upload_required`.
+- Creates personal document metadata through `create_document()`.
+- Queues `process_document_upload_background()`.
+- Persists tags in the document record.
+- Propagates tags to chunks and blob metadata when tags change.
+- Invalidates personal search cache after upload and tag operations.
+
+### Workspace Delete UI
+
+`application/single_app/static/js/workspace/workspace-documents.js` already centralizes document deletion through `promptDocumentDeleteMode()`, `requestDocumentDeletion()`, and `window.deleteDocument()`. It also has a specialized File Sync warning flow. The linked-conversation warning can follow that same modal pattern.
+
+## Implemented Behavior
+
+For each chat upload:
+
+1. Run the current chat upload authorization and file validation checks.
+2. Ensure a personal conversation exists and is owned by the current user.
+3. Check whether the personal workspace handoff is eligible.
+4. If eligible, create a personal workspace document from the same uploaded temp file and queue normal workspace processing.
+5. Create a lightweight workspace-backed chat file message with metadata that points to the workspace document and uses the resolved workspace filename.
+6. Return the same client response shape, with optional additional fields for future UI use.
+7. Skip legacy chat extraction, `file_content` storage, chat image blob storage, and chat tabular blob storage for the successful workspace-backed branch.
+8. If the workspace handoff is not eligible because the personal workspace is unavailable, continue through the existing chat-only upload path. If the workspace handoff is eligible but fails, return an upload error instead of silently storing the file in chat-local storage.
+
+Eligibility should be conservative:
+
+- `enable_user_workspace` is true.
+- The authenticated user is allowed to upload files through the existing gates.
+- The file extension is supported by personal workspace ingestion.
+- Required workspace dependencies are configured enough to create metadata and queue processing.
+- The request is for a personal chat conversation. Collaboration and group chat upload handoff should be separate follow-up work.
+
+## Data Model
+
+The workspace document should use existing document metadata wherever possible, plus explicit linkage fields. Tags are useful for search/filtering, but lifecycle logic should not depend only on user-editable tags.
+
+Implemented personal document fields:
+
+```json
+{
+  "source_type": "chat_upload",
+  "source_subtype": "personal_conversation_attachment",
+  "created_from_chat_upload": true,
+  "conversation_id": "<conversation_id>",
+  "conversation_title_at_upload": "<conversation title>",
+  "chat_message_id": "<message_id>",
+  "chat_upload_delete_with_conversation": true,
+  "chat_upload_link_state": "linked",
+  "chat_upload_linked_at": "<utc iso timestamp>",
+  "chat_upload_original_filename": "<uploaded filename>",
+  "chat_upload_workspace_filename": "<resolved unique workspace filename>",
+  "source_original_file_name": "<uploaded filename>"
+}
+```
+
+Implemented chat message metadata:
+
+```json
+{
+  "workspace_attachment": {
+    "scope": "personal",
+    "document_id": "<document_id>",
+    "conversation_id": "<conversation_id>",
+    "link_state": "linked",
+    "processing_status": "queued"
+  }
+}
+```
+
+Implemented tags on the personal workspace document:
+
+```json
+[
+  "conversations"
+]
+```
+
+The conversation ID is stored in explicit metadata fields such as `conversation_id`, `conversation_url`, and `chat_message_id`. Lifecycle and search association logic must use those metadata fields, not a user-visible tag.
+
+## Tag Ramifications
+
+Using normal document tags means the `conversations` tag will naturally flow into:
+
+- Personal workspace document lists.
+- Personal workspace tag filters.
+- Chat workspace tag filters.
+- Azure AI Search chunk metadata as `document_tags`.
+- Blob metadata when enhanced citations are enabled.
+
+The conversation ID is intentionally not added as a tag because UUID-like tags clutter folder and tag pickers without helping normal workspace organization. The metadata fields remain authoritative for finding linked documents, showing conversation warnings, and deleting selected documents with a conversation.
+
+Optional tag-definition metadata can still identify the reserved `conversations` tag as system-generated:
+
+```json
+{
+  "conversations": {
+    "color": "#6c757d",
+    "created_at": "<utc iso timestamp>",
+    "is_system": true,
+    "system_tag_type": "chat_upload"
+  }
+}
+```
+
+The first implementation can skip hidden tag UI if that is too much surface area. The important product rule is that only the general `conversations` tag should be visible to users; per-conversation linkage belongs in metadata.
+
+## Backend Implementation Plan
+
+### Shared Upload Helper
+
+Avoid calling one Flask route from another. Factor the workspace upload internals into a helper that both `POST /api/documents/upload` and `POST /upload` can use.
+
+A likely helper shape:
+
+```python
+def create_personal_workspace_document_from_upload(
+    *,
+    user_id,
+    temp_file_path,
+    original_filename,
+    tags=None,
+    source_metadata=None,
+):
+    """Create document metadata, queue background processing, and return the document record."""
+```
+
+The helper should own:
+
+- `secure_filename()` handling or receive a sanitized filename from the caller.
+- Document metadata creation with tags and source metadata.
+- Background processing queue setup.
+- Search cache invalidation.
+- Structured logging.
+
+### Chat Upload Route
+
+`POST /upload` keeps the current fallback behavior in place, but the eligible workspace branch now replaces the old chat-local file processing path:
+
+- Queue the workspace document from a temp-file copy.
+- Resolve a unique personal workspace filename before calling `create_document()` so separate chat uploads do not enter the workspace revision path solely because their display names match.
+- Create a `role = file` message with `file_content_source = workspace`, `workspace_document_id`, and `metadata.workspace_attachment`.
+- Return immediately after writing the workspace-backed message.
+- Avoid writing `file_content`, chat image blobs, or chat tabular blobs for the successful workspace-backed branch.
+- Refresh chat progress from `GET /api/documents/<document_id>` and normalize the response before reading `status` and `percentage_complete`.
+- Start a completion watcher from the upload response's `workspace_document_id` so live status updates do not depend only on the rendered card hydration path.
+- When processing completes successfully, collapse the progress/status details and select the completed document in the Workspaces document picker without changing the current document action from Search.
+- After background processing finishes or fails, sync the linked chat message's `metadata.workspace_attachment` from the workspace document record so message reloads preserve the current status.
+
+If the workspace branch is unavailable because the personal workspace is disabled, the route falls back to the existing chat-only extraction/storage path. If the workspace branch is eligible but cannot be safely queued, the route returns an upload error instead of falling through to chat-local storage.
+
+### Automatic Conversation Context
+
+Creating a workspace document is not enough by itself if the user still has to select that document manually. The chat answer pipeline should automatically include linked workspace documents for the active conversation.
+
+Recommended behavior:
+
+- Add a helper that returns active, fully processed workspace document IDs linked to a conversation and owned by the current user.
+- Merge those IDs with explicit `selected_document_ids` before search-only document retrieval in both regular and streaming chat routes.
+- Keep explicit user selections and Assigned Knowledge restrictions respected.
+- Exclude linked documents that are still processing, failed, deleted, or unlinked.
+- Include metadata in capability usage logs so administrators can distinguish user-selected documents from auto-linked chat-upload documents.
+
+Document actions need a small UX decision:
+
+- Search can safely include all ready linked documents automatically.
+- Analyze should offer linked chat-upload documents as preselected candidates, but should still respect document action limits.
+- Compare should not silently choose comparison pairs. It can make linked documents easy to pick, but the user should choose source and target when multiple linked files exist.
+
+## Delete Lifecycle
+
+### Conversation Deleted First
+
+Single and bulk conversation deletion live in `application/single_app/route_backend_conversations.py`. Single conversation metadata now includes `linked_workspace_documents`, which is built from personal workspace documents where `created_from_chat_upload` is true and `conversation_id` matches the conversation being deleted.
+
+The single conversation delete modal lists those linked workspace documents with checkboxes. The default state keeps every workspace document. Users can select one document or use select all, and only those selected document IDs are sent to `DELETE /api/conversations/<conversation_id>` as `delete_workspace_document_ids`.
+
+Implemented policy:
+
+- If no workspace documents are selected, all linked workspace documents remain in the personal workspace and continue to follow the document retention policy.
+- If one or more workspace documents are selected, the backend validates them against the current user and conversation before calling `delete_document_revision(..., delete_mode="all_versions")`.
+- Single hard delete still removes chat-scoped blob-backed attachment files and chat messages.
+- Bulk conversation delete retains linked workspace documents because there is no per-document selection dialog in the bulk flow.
+- Archive-enabled conversation delete retains linked workspace documents by default, but still deletes workspace documents that the user explicitly selects in the delete dialog.
+- Lifecycle decisions use explicit metadata fields, not tags.
+
+### Workspace Document Deleted First
+
+`DELETE /api/documents/<document_id>` should inspect the target document before showing or completing deletion.
+
+Recommended flow:
+
+1. The delete request detects `created_from_chat_upload = true` and an active `conversation_id`.
+2. If the client did not already confirm the linked delete, return `409` with a structured payload.
+3. `workspace-documents.js` shows the existing `documentDeleteModal` with a linked-conversation warning.
+4. The modal shows the conversation ID and a link to `/chats?conversation_id=<conversation_id>`.
+5. If the user confirms, the delete request continues and marks the chat message link state as `workspace_document_deleted`.
+
+Example `409` response:
+
+```json
+{
+  "error": "conversation_linked_document_delete_requires_confirmation",
+  "message": "This document is associated with a conversation.",
+  "conversation_id": "<conversation_id>",
+  "conversation_url": "/chats?conversation_id=<conversation_id>",
+  "document_id": "<document_id>"
+}
+```
+
+The chat attachment should remain visible after workspace deletion, but the metadata should show that workspace processing is no longer available. If the first implementation keeps legacy chat file content, the existing chat link can continue to open. If a later implementation makes chat attachments workspace-only, the UI must show a clear deleted-document state.
+
+## Failure Modes
+
+- Workspace disabled: use the existing chat-only flow.
+- Workspace document creation fails before metadata is written: log the failure and return an upload error so the user does not unknowingly create a chat-local attachment.
+- Workspace metadata is created but background processing fails: keep the chat attachment, show the document processing error in the workspace, and keep the link state as `linked_failed_processing` or equivalent.
+- Chat message creation fails after workspace document creation: delete the newly created workspace document or mark it as `orphaned_chat_upload` and surface it in logs. Prefer rollback for a clean user experience.
+- User deletes the conversation while workspace processing is still running: stop polling for selected documents that are deleted with the conversation, retain unselected documents, and make background processing tolerate missing metadata.
+- User deletes or renames the `conversations` tag: lifecycle behavior must still work because metadata fields remain authoritative.
+- User shares a linked workspace document: conversation delete should retain the document by default or require an explicit policy decision.
+- Re-uploading the same filename in any chat: create a new workspace document with a collision-free filename and keep each chat message linked to its corresponding document ID.
+
+## Permissions And Security
+
+- Keep `POST /upload` guarded by `enable_chat_file_uploads`, optional `ChatFileUploadUser`, login, `user_required`, and `file_upload_required`.
+- Do not use the workspace route decorator as the only guard for handoff; check `enable_user_workspace` inside the chat route and fall back when it is false.
+- Do not expose raw settings to the frontend when adding UI state.
+- Ensure linked-document lookup verifies `document.user_id == current_user_id`.
+- Ensure conversation lookup verifies `conversation.user_id == current_user_id`.
+- Do not allow user-supplied `conversation_id` to link a document to another user's conversation.
+- Treat conversation ID metadata as association data, not an authorization boundary.
+
+## Frontend Plan
+
+### Chat UI
+
+The upload client still accepts the existing `conversation_id` and optional `title` response shape. When the server also returns `workspace_document_id`, the client starts a completion watcher, updates the visible chat card as processing advances, and selects the completed personal workspace document in the Workspaces document picker.
+
+Optional chat enhancements:
+
+- Add a subtle workspace indicator to uploaded file messages when a workspace document exists.
+- Show processing state if the workspace document is still being indexed.
+- Offer an "Open in Workspace" action for linked documents.
+- Show a clear state if the workspace document was deleted but the chat attachment remains.
+
+### Workspace UI
+
+Extend the existing document delete modal pattern:
+
+- Add `promptConversationLinkedDocumentDeleteAction(deleteInfo)` next to `promptSyncedDocumentDeleteAction(deleteInfo)`.
+- Reuse `documentDeleteModalBody.replaceChildren(...)` to avoid unsafe HTML string assembly.
+- Include the conversation ID as text and link to `/chats?conversation_id=<id>`.
+- Continue supporting current-only and all-versions delete choices after the user acknowledges the conversation link.
+
+## Testing Plan
+
+Functional tests should cover:
+
+- Chat upload with personal workspace enabled creates both a chat message and a personal workspace document.
+- Chat upload with personal workspace disabled uses the existing chat-only flow.
+- Workspace document has the `conversations` tag only; the conversation ID is stored in metadata.
+- Repeated chat uploads with the same filename resolve distinct workspace filenames before document creation.
+- Workspace document chunks receive the same tags after processing.
+- Chat message metadata stores the linked workspace document ID.
+- Chat answer search automatically includes ready linked workspace documents for the active conversation.
+- Conversation delete modal lists linked workspace documents with individual and select-all choices.
+- Conversation hard delete deletes only the selected linked workspace documents and chunks.
+- Conversation hard delete retains unselected linked workspace documents so they follow the document retention policy.
+- Conversation archive-enabled delete retains linked workspace documents.
+- Bulk conversation delete retains linked workspace documents unless a future explicit bulk selection flow is added.
+- Workspace document delete first returns a linked-conversation warning payload and then deletes after confirmation.
+- The warning payload rejects attempts to delete another user's linked document or link to another user's conversation.
+- Tag deletion or rename does not break lifecycle cleanup because metadata fields are authoritative.
+
+UI tests should cover:
+
+- Uploading from chat still renders an attachment or image in the message list.
+- The workspace document appears in the personal workspace list after upload.
+- The workspace delete modal shows the conversation ID and navigable conversation link for linked documents.
+- The chat page opens from `/chats?conversation_id=<conversation_id>`.
+
+## Staged Implementation
+
+1. Add shared workspace-upload helper and chat-upload handoff metadata.
+2. Create linked workspace documents in compatibility mode while preserving current chat message content.
+3. Add automatic linked-document inclusion to chat search context.
+4. Add selectable linked-document deletion to the single conversation delete flow and retain linked documents during bulk deletes.
+5. Add workspace delete warning and link-state updates.
+6. Add optional UI affordances: workspace indicator in chat messages and hidden/reserved tag behavior.
+7. Revisit storage duplication once behavior is stable, then decide whether some chat file types can become workspace-reference-only.
+
+## Open Decisions
+
+- Should the reserved `conversations` tag be hidden from normal tag management, or remain visible as a useful high-level folder/filter?
+- Should archive-enabled conversation deletion delete linked workspace documents, retain them, or be controlled by a new setting?
+- When a chat-uploaded document is edited, shared, or revised in the workspace, should it remain selectable for deletion with the conversation or require an additional warning?
+- Should linked workspace documents be automatically included only for search, or also preselected for analyze flows?
+- Should group and collaborative conversations get similar workspace handoff behavior later, and if so should they target group workspaces instead of personal workspaces?

+# Collaborative Conversations Foundation (v0.241.007)
+
+Fixed and implemented in version: **0.241.007**
+
+## Overview
+
+This document describes the initial backend foundation for collaborative conversations in SimpleChat.
+The implementation adds new collaboration-specific conversation, message, and user-state models without changing the current single-user chat behavior.
+
+The goal of this first slice is to establish safe multi-user primitives before integrating the full collaborative chat user experience into the existing chat page.
+
+## Dependencies
+
+- Flask route registration and authentication decorators
+- Azure Cosmos DB containers for collaborative conversations, messages, and per-user state
+- Existing group RBAC enforcement via `assert_group_role(...)`
+- Existing application cache infrastructure for replayable SSE event streams
+
+## Technical Specifications
+
+### Architecture Overview
+
+The collaborative conversation foundation introduces three new persistence areas:
+
+- `collaboration_conversations`
+- `collaboration_messages`
+- `collaboration_user_state`
+
+Single-user conversations remain unchanged in the existing `conversations` and `messages` containers.
+This keeps the current chat experience stable while the collaborative workflow is built incrementally.
+
+### Conversation Modes
+
+Two new collaborative conversation types are defined:
+
+- `personal_multi_user`
+- `group_multi_user`
+
+Personal collaborative conversations:
+
+- Use owner-managed invites
+- Require invited users to accept before they can participate
+- Are designed for personal and public knowledge only
+
+Group collaborative conversations:
+
+- Are visible to current members of one group
+- Reuse group RBAC checks on every protected operation
+- Are designed for one locked group plus optional public knowledge
+
+### API Endpoints
+
+The new backend route module exposes the following endpoints:
+
+- `GET /api/collaboration/conversations`
+- `POST /api/collaboration/conversations`
+- `GET /api/collaboration/conversations/<conversation_id>`
+- `POST /api/collaboration/conversations/<conversation_id>/invite-response`
+- `POST /api/collaboration/conversations/<conversation_id>/members`
+- `DELETE /api/collaboration/conversations/<conversation_id>/members/<member_user_id>`
+- `GET /api/collaboration/conversations/<conversation_id>/messages`
+- `POST /api/collaboration/conversations/<conversation_id>/messages`
+- `POST /api/collaboration/conversations/<conversation_id>/typing`
+- `GET /api/collaboration/conversations/<conversation_id>/events`
+
+### Configuration
+
+The foundation introduces a new setting in `functions_settings.py`:
+
+- `enable_collaborative_conversations`
+
+This setting is intended to control rollout while the broader collaborative UI and AI orchestration are implemented in later passes.
+
+### File Structure
+
+Key files added in this slice:
+
+- `application/single_app/collaboration_models.py`
+- `application/single_app/functions_collaboration.py`
+- `application/single_app/route_backend_collaboration.py`
+- `functional_tests/test_collaborative_conversation_foundation.py`
+
+## Usage Instructions
+
+This slice is backend-first.
+It establishes the conversation lifecycle, invite state model, human-message persistence, typing events, and a conversation-wide SSE stream for collaboration events.
+
+Frontend integration is intentionally deferred so the current single-user chat experience is not destabilized while the shared experience is still under construction.
+
+## Testing and Validation
+
+Related functional test:
+
+- `functional_tests/test_collaborative_conversation_foundation.py`
+
+Validated behaviors in this slice:
+
+- Personal collaborative conversation creation with pending invite state
+- Invite acceptance transitions from pending to accepted
+- Group collaborative conversation creation with a locked group scope
+- Collaborative human-message document construction with reply linkage
+
+## Known Limitations
+
+- Existing `/chats` UI is not yet wired to the new collaboration APIs
+- Explicit AI request orchestration for collaborative conversations is not yet connected to the existing chat generation pipeline
+- Read receipts and presence are deferred beyond this initial foundation

+# Collaborative Conversation UI Upgrade (v0.241.008)
+
+Fixed and implemented in version: **0.241.008**
+
+## Overview
+
+This document describes the first `/chats` UI integration for collaborative conversations.
+The feature keeps personal and group conversations single-user by default, then upgrades personal conversations into shared chats when participants are added.
+
+This slice focuses on the user-visible entry points the chat page needs before explicit shared AI workflows are layered on top.
+
+## Dependencies
+
+- Collaborative conversation foundation routes and Cosmos containers
+- Existing `/chats` page layout, sidebar loaders, and conversation details modal
+- Local user settings records used for collaborator suggestions
+- Existing Bootstrap modal infrastructure on the chat page
+
+## Technical Specifications
+
+### Architecture Overview
+
+The chat UI now treats collaborative conversations as a first-class conversation kind within the existing personal chat experience.
+
+The integration adds:
+
+- a collaboration-aware conversation list merge in the main rail and sidebar
+- a dedicated frontend collaboration module for message loading, event streaming, typing state, and participant management
+- personal conversation upgrade support that converts a legacy personal conversation into a collaborative one when members are added
+
+### API Endpoints
+
+The UI integration relies on the existing collaborative conversation APIs and adds two new browser-facing helpers:
+
+- `POST /api/collaboration/conversations/from-personal/<conversation_id>/members`
+- `GET /api/user/collaboration-suggestions`
+
+The first endpoint upgrades a legacy personal conversation and invites the selected participant in one request.
+The second endpoint returns suggestions from recent collaborator settings and locally stored user records instead of live Entra lookups.
+
+### UI Entry Points
+
+Participant management is now available from:
+
+- the conversation details modal
+- the left-hand conversation actions in both chat conversation lists
+- the `@` mention workflow in the chat composer
+
+All participant adds use a confirmation modal before the invite or conversion request is sent.
+
+### File Structure
+
+Key files updated in this slice:
+
+- `application/single_app/static/js/chat/chat-collaboration.js`
+- `application/single_app/static/js/chat/chat-conversations.js`
+- `application/single_app/static/js/chat/chat-sidebar-conversations.js`
+- `application/single_app/static/js/chat/chat-messages.js`
+- `application/single_app/static/js/chat/chat-conversation-details.js`
+- `application/single_app/templates/chats.html`
+- `application/single_app/static/css/chats.css`
+
+## Usage Instructions
+
+Users can continue creating and using personal conversations exactly as before.
+When a participant is added to a personal conversation, SimpleChat upgrades that conversation into a collaborative conversation and keeps the user in the shared chat flow.
+
+Collaborator suggestions are intentionally limited to recent collaborators and local user records that already exist in SimpleChat.
+This keeps the feature fast and avoids adding a live directory dependency to the compose experience.
+
+## Testing and Validation
+
+Related tests:
+
+- `functional_tests/test_collaboration_legacy_message_conversion.py`
+- `ui_tests/test_chat_collaboration_ui_scaffolding.py`
+
+Validated behaviors in this slice:
+
+- legacy personal messages can be converted into collaboration-safe transcript records
+- uploaded files and assistant messages preserve the expected sender semantics during conversion
+- the chats page loads the collaboration modals and mention container without collaboration-specific browser errors
+
+## Known Limitations
+
+- explicit shared AI invocation is still a later slice
+- full end-to-end collaborative UI workflows require authenticated UI environment setup and seeded conversation data
+- group collaborative conversation management is not yet expanded to a distinct shared group workflow beyond the current shared-chat scaffolding

+# Control Center Activity Log Auto-Refresh
+
+Fixed/Implemented in version: **0.241.028**
+
+## Overview and Purpose
+
+The Control Center Activity Logs tab now lets admins enable browser-side auto-refresh while they monitor recent activity. The control is designed for live operations views where admins previously stayed on the page and repeatedly clicked Reload.
+
+Dependencies: `application/single_app/templates/control_center.html`, `application/single_app/static/js/control-center.js`, browser `localStorage`, Bootstrap form controls, and the existing Activity Logs API.
+
+## Technical Specifications
+
+Architecture overview:
+
+- The Activity Logs tab exposes an Auto-refresh switch, interval slider, seconds input, and quick interval presets.
+- The interval range is 1 to 300 seconds with a 30-second default.
+- The browser stores the enabled state and interval in `localStorage` using `simplechat_activityLogsAutoRefreshEnabled` and `simplechat_activityLogsAutoRefreshIntervalSeconds`.
+- Auto-refresh only schedules while the Activity Logs tab is active and the document is visible.
+- Auto-refresh pauses after authorization failures or repeated refresh errors to avoid noisy background polling.
+
+Configuration options:
+
+- Minimum interval: 1 second
+- Maximum interval: 300 seconds
+- Default interval: 30 seconds
+- Quick presets: 1s, 10s, 30s, 60s, 5m
+
+File structure:
+
+- `application/single_app/templates/control_center.html` - Activity Logs auto-refresh toolbar and responsive styling.
+- `application/single_app/static/js/control-center.js` - persisted auto-refresh state, interval controls, timer scheduling, and failure handling.
+- `functional_tests/test_control_center_activity_logs_auto_refresh.py` - source-level regression coverage.
+- `ui_tests/test_control_center_activity_logs_auto_refresh.py` - browser workflow and persistence validation.
+- `application/single_app/config.py` - version updated to 0.241.028 for this feature.
+
+## Usage Instructions
+
+1. Open Control Center.
+2. Select Activity Logs.
+3. Turn on Auto-refresh.
+4. Set the interval with a quick preset, slider, or seconds input.
+
+Integration points:
+
+- Manual Reload still works and resets the next auto-refresh timer.
+- Search, activity type, and per-page changes continue to reload immediately and then resume the configured interval.
+- Interval choices persist per browser and device.
+
+## Testing and Validation
+
+Test coverage:
+
+- `functional_tests/test_control_center_activity_logs_auto_refresh.py`
+- `ui_tests/test_control_center_activity_logs_auto_refresh.py`
+
+Validation highlights:
+
+- Confirms the template exposes the switch, range control, seconds input, presets, status region, and responsive toolbar styling.
+- Confirms the JavaScript persists the enabled state and interval, schedules with `setTimeout`, pauses while hidden, and stops after auth or repeated failures.
+- Confirms the browser workflow can enable auto-refresh, change intervals, persist settings, and trigger repeated Activity Logs API requests.
+
+Known limitations:
+
+- Auto-refresh is a per-browser preference, not an administrator-wide server setting.
+- The timer refreshes the current Activity Logs page and filters; it does not force a metrics recalculation.

+# Control Center Auto-Refresh Schedule
+
+Implemented in version: **0.241.026**
+
+## Overview
+
+Control Center administrators can now configure a daily UTC refresh schedule for Control Center metrics. The setting is enabled by default and runs at **06:00 UTC** unless an administrator changes the time under Admin Settings > Control Center.
+
+## Technical Specifications
+
+- **Settings defaults**: `control_center_auto_refresh_enabled`, `control_center_auto_refresh_time`, `control_center_auto_refresh_hour`, `control_center_auto_refresh_minute`, and `control_center_auto_refresh_next_run` are defined in `application/single_app/functions_settings.py`.
+- **Schedule helpers**: `application/single_app/functions_control_center.py` normalizes the configured time and calculates the next daily UTC run.
+- **Background execution**: `application/single_app/background_tasks.py` checks the schedule every five minutes and uses the existing distributed lock pattern before calling the Control Center refresh.
+- **Admin UI**: `application/single_app/templates/admin_settings.html` exposes the enable toggle, UTC time input, and next-run display under the Control Center settings tab.
+- **Status API**: `application/single_app/route_backend_control_center.py` returns auto-refresh schedule metadata from `/api/admin/control-center/refresh-status`.
+- **Version update**: `application/single_app/config.py` was updated to version **0.241.026** for this feature.
+
+## Usage Instructions
+
+1. Open Admin Settings.
+2. Select the Control Center tab.
+3. Use Automatic Data Refresh to enable or disable the daily refresh.
+4. Set the refresh time in UTC. The default is 06:00.
+5. Save settings to calculate the next scheduled run.
+
+## Testing and Validation
+
+- Functional coverage: `functional_tests/test_control_center_auto_refresh_schedule.py`
+- UI coverage: `ui_tests/test_admin_settings_control_center_auto_refresh.py`
+- The background scheduler preserves the existing manual refresh behavior and only runs the automatic refresh when the saved next-run timestamp is due.
+
+## Known Limitations
+
+- The scheduler checks every five minutes, so the refresh may start a few minutes after the configured time.
+- The configured time is UTC-only to avoid ambiguity across app instances and regional deployments.

+# Conversation Feed Pagination
+
+Implemented in version: **0.241.112**
+
+## Overview
+
+Conversation Feed Pagination reduces chat startup work by loading a prioritized first page instead of sending every accessible conversation to the browser. The first feed response includes pinned conversations, unread conversations, and the first page of recent conversations. Additional recent conversations load through a cursor when the user clicks **Load more conversations** or scrolls near the bottom of the list.
+
+## Dependencies
+
+- Flask conversation APIs in `application/single_app/route_backend_conversations.py`
+- Feed merge helpers in `application/single_app/functions_conversation_feed.py`
+- Chat list rendering in `application/single_app/static/js/chat/chat-conversations.js`
+- Sidebar conversation rendering in `application/single_app/static/js/chat/chat-sidebar-conversations.js`
+- Collaboration notification read state from the notifications container
+
+## Technical Specifications
+
+The `/api/conversations/feed` endpoint returns a merged feed payload with:
+
+- All visible pinned conversations on the first page
+- All visible unread conversations on the first page
+- A cursor-paged window of recent non-priority conversations
+- A hidden conversation count for the show-hidden control
+- A `next_cursor` value when more recent conversations are available
+
+The backend merges legacy personal conversations and collaborative conversations into one response shape. Hidden conversations are excluded unless `include_hidden=true` is passed. Quick title search is sent to the backend so it searches beyond the currently loaded page.
+
+## Usage Instructions
+
+Users do not need to enable the feature. Opening the chat page loads the first prioritized feed automatically. More conversations can be loaded from the list control or by scrolling near the bottom of the conversation list.
+
+## Testing and Validation
+
+- Functional coverage: `functional_tests/test_conversation_feed_pagination.py`
+- UI coverage: `ui_tests/test_chat_sidebar_single_startup_load.py`
+
+Known limitation: phase one still uses the existing collaboration access loaders internally. A future feed index can further reduce backend reads for users with very large collaborative conversation histories.

+# Cosmos Container Policy Enforcement
+
+Implemented in version: **0.241.153**
+
+## Overview
+
+Cosmos container policy enforcement lets admins apply one global SimpleChat throughput automation policy to every dedicated-throughput Cosmos container. The policy also applies automatically to containers discovered later, so admins do not need to configure each new container manually.
+
+Dependencies:
+
+- Cosmos throughput monitoring and scaling controls in Admin Settings.
+- Azure Resource Manager throughput read/write permissions for the app identity.
+- Azure Monitor metrics read permissions for RU utilization data.
+
+## Technical Specifications
+
+Architecture overview:
+
+- The setting `cosmos_throughput_enforce_container_defaults` is persisted with the Admin Settings Cosmos throughput configuration.
+- When enabled, `get_container_policy()` resolves each container policy from the global automation thresholds, intervals, step sizes, and guardrails.
+- Existing per-container cooldown timestamps are preserved so a recently scaled container does not immediately scale again after enforcement is enabled.
+- New containers inherit the same enforced policy when they are discovered by Refresh or the background autoscale loop.
+
+Configuration options:
+
+- Enable Cosmos throughput automation.
+- Configure the global scale-up/down thresholds, intervals, RU step sizes, and min/max guardrails.
+- Enable Enforce global policy for all containers.
+- Use Apply Global Policy in the Containers modal to stage the current global policy onto currently discovered containers.
+
+File structure:
+
+- `application/single_app/functions_cosmos_throughput.py`
+- `application/single_app/route_frontend_admin_settings.py`
+- `application/single_app/templates/admin_settings.html`
+- `application/single_app/static/js/admin/admin_settings.js`
+- `functional_tests/test_cosmos_throughput_autoscale_logic.py`
+- `ui_tests/test_admin_cosmos_throughput_settings_ui.py`
+
+## Usage Instructions
+
+1. Open Admin Settings and go to the Scale tab.
+2. Enable Cosmos throughput automation.
+3. Configure the global thresholds, intervals, RU step sizes, and guardrails.
+4. Enable Enforce global policy for all containers.
+5. Save Admin Settings.
+
+When enabled, all dedicated-throughput containers use the same SimpleChat automation policy. Containers using shared database throughput remain visible but are not individually scalable until they have dedicated throughput.
+
+## Testing and Validation
+
+Test coverage:
+
+- Functional test verifies enforced policy overrides saved per-container settings while preserving cooldown timestamps.
+- Functional test verifies future containers with no saved row policy inherit the global policy.
+- UI test verifies the enforcement switch and Apply Global Policy action are present.
+
+Known limitations:
+
+- This feature applies SimpleChat background scaling policy consistently. It does not convert Cosmos manual throughput resources into Cosmos autoscale throughput resources.

+# Cosmos Native Autoscale Conversion
+
+## Implemented in Version
+
+Implemented in version: **0.241.159**
+
+Migration action fixed in version: **0.241.160**
+
+Related config.py version update: `VERSION = "0.241.160"`
+
+## Overview
+
+SimpleChat admins can convert Cosmos DB manual throughput offers to native Cosmos autoscale from the Admin Settings Scale tab. The feature supports shared database throughput and dedicated container throughput, and it can be applied through the global container policy for current and future containers.
+
+## Dependencies
+
+- Azure Resource Manager access to the configured Cosmos DB account, database, and throughput settings.
+- The SimpleChat Cosmos Throughput Operator role assigned to the web app identity with throughput read/write, `migrateToAutoscale/action`, and migration operation-result read permissions.
+- Cosmos DB SQL database or container throughput using manual provisioned throughput.
+
+## Technical Specifications
+
+### Architecture
+
+Manual-to-autoscale conversion is handled by `functions_cosmos_throughput.py`. When conversion is requested for an existing manual throughput offer, SimpleChat calls the Cosmos throughput migration action:
+
+```text
+POST {throughputSettings/default}/migrateToAutoscale
+```
+
+After an offer is already in native Cosmos autoscale mode, SimpleChat can update the autoscale max throughput with:
+
+```json
+{
+    "properties": {
+        "resource": {
+            "autoscaleSettings": {
+                "maxThroughput": 5000
+            }
+        }
+    }
+}
+```
+
+The conversion target preserves the current manual RU/s as the autoscale max throughput, rounded up to Cosmos autoscale's 1000 RU/s increment. Minimum and maximum RU guardrails still apply.
+
+### API Endpoints
+
+- `POST /api/admin/settings/cosmos-throughput/convert-autoscale`
+  - Admin-only endpoint.
+  - Optional JSON body field: `container_name`.
+  - Converts the database throughput when `container_name` is omitted.
+  - Converts a dedicated container throughput offer when `container_name` is supplied.
+
+### Configuration Options
+
+- `cosmos_throughput_convert_manual_to_autoscale_enabled`
+  - Enables background conversion for manual throughput offers.
+  - Applies to database throughput when the database has a scalable manual throughput offer.
+  - Applies to dedicated containers when global policy enforcement is enabled.
+
+- Container policy field: `convert_manual_to_autoscale_enabled`
+  - Enables conversion for a specific dedicated-throughput container.
+  - Inherited from the global setting when global policy enforcement is enabled.
+
+### File Structure
+
+- `application/single_app/functions_cosmos_throughput.py`
+- `application/single_app/route_backend_settings.py`
+- `application/single_app/route_frontend_admin_settings.py`
+- `application/single_app/templates/admin_settings.html`
+- `application/single_app/static/js/admin/admin_settings.js`
+- `functional_tests/test_cosmos_throughput_autoscale_logic.py`
+- `ui_tests/test_admin_cosmos_throughput_settings_ui.py`
+
+## Usage Instructions
+
+1. Open Admin Settings and select the Scale tab.
+2. Enable Cosmos throughput automation.
+3. Enable **Convert manual throughput to Cosmos autoscale**.
+4. For container-targeted deployments, enable **Enforce global policy for all containers** to apply the conversion setting to all current and future dedicated-throughput containers.
+5. Save Admin Settings.
+6. Use Refresh or the background scheduler to discover current throughput state.
+
+Admins can also use the **Convert** action for database-level manual throughput or the lightning action button in the container table or policy modal to convert a single manual dedicated-throughput container immediately.
+
+## Testing and Validation
+
+- Functional tests validate opt-in conversion, global policy inheritance, and ARM autoscale payload shape.
+- UI tests validate that the Admin Settings Scale tab exposes the global conversion switch, container policy field, and conversion endpoint wiring.
+- Validation should include `py_compile`, focused pytest, `node --check`, and CRLF-aware whitespace checks.
+
+## Known Limitations
+
+- Conversion is not attempted for serverless capacity, shared-throughput containers without a dedicated throughput offer, or containers whose current manual RU/s exceeds the configured maximum guardrail.
+- Background automation converts one eligible throughput offer per scheduler run.
+- The feature changes Cosmos native throughput mode; it is separate from SimpleChat's scale-up and scale-down threshold automation.

+
+## Overview
+
+Custom Pages let app teams that deploy SimpleChat add trusted, deployment-time pages under the `/custom` namespace without changing the core application route code. The feature is controlled by the Admin Settings toggle `enable_custom_pages` and fails closed when disabled.
+
+## Dependencies
+
+- Flask host routes in `application/single_app/route_custom_pages.py`
+- Cosmos DB metadata container `custom_pages`, configured in `application/single_app/config.py`
+- Static file folders under `application/single_app/custom_pages/`: `assets`, `css`, `html`, `js`, `json`, and `python`
+- Admin Settings metadata designer in `application/single_app/templates/admin_settings.html`
+
+## Technical Specifications
+
+Custom Pages uses always-registered host routes and request-time dispatch. Static page metadata is stored in Cosmos DB so simple page definitions persist across container lifecycle events. Python-backed pages are trusted code shipped with the deployed artifact and discovered from `custom_pages/python` using `CustomPageExtension` subclasses or the `@custom_page` decorator.
+
+The host routes are:
+
+- `/custom/<slug>` for page rendering
+- `/custom/<slug>.html` as a familiar static-page alias for page rendering
+- `/custom/assets/<slug>/<folder>/<path:filename>` for declared static assets
+- `/api/custom/<slug>/<path:operation>` for Python-backed custom page operations
+- `/api/admin/custom-pages` for Admin Settings metadata management
+
+Static pages are rendered through `custom_page_shell.html` after the host route applies `@login_required` and `@user_required`. Static HTML content is treated as trusted deployment-time app-team content and is not end-user supplied.
+
+## Configuration Options
+
+- `enable_custom_pages`: Enables or disables all `/custom` page and asset routes.
+- `custom_pages_menu_name`: Controls the navigation label when pages are grouped.
+- `custom_pages_force_menu`: Forces custom pages to display as a menu even when only one or two pages exist.
+
+The feature version was updated in `application/single_app/config.py` from `0.242.022` to `0.242.023`.
+
+The example page set was added with version `0.242.024`.
+
+Version `0.242.025` added a restart acknowledgement modal for first-time enablement and records the acknowledgement to `activity_logs` as `custom_pages_enabled_acknowledged`.
+
+Version `0.242.026` replaced comma-separated CSS, JavaScript, asset, and JSON text fields with explicit add/remove file list editors.
+
+Version `0.242.027` added `/custom/<slug>.html` as a compatibility alias and improved modal spacing for deployed files and publishing toggles.
+
+Version `0.242.028` added a single-source developer guide modal.
+
+Version `0.242.029` moved the canonical guide source into `application/single_app/docs/how-to/custom_pages.md` so non-container deployments and ACR-built containers receive the guide with the app artifact. The docs how-to page now links to that in-app source instead of duplicating the guide.
+
+Version `0.242.030` clarified forced menu behavior with page count badges and bounded scrolling in sidebar, top navigation, and mobile navigation menus.
+
+Version `0.242.031` changed large custom page sets to use a dedicated drawer when more than five pages are available. One or two pages can stay inline unless the menu is forced, three to five pages use a compact grouped menu, and six or more pages open the drawer with its own scroll area.
+
+Version `0.242.032` added a shared drawer trigger handler so mobile navigation closes before the Custom Pages drawer opens.
+
+Version `0.242.033` added `cat.mp4` as a declared asset in the static example page and renders it with an HTML video viewer.
+
+Version `0.242.034` removed the admin bypass from custom page authorization. When a page has Allowed Roles configured, every user must have at least one exact matching role in the current session.
+
+Version `0.242.035` treats `Admin` as satisfying the base `User` role while still requiring exact matches for all other page-specific roles.
+
+Version `0.242.036` added access levels, a repo-shipped Request Access static page, a one-click Admin Settings action to create its metadata, and an access-denied home-page button for signed-in users without app roles. The earlier learning examples were moved out of live custom pages into `application/single_app/docs/how-to/custom_pages_examples/`.
+
+Version `0.242.037` added post-create guidance for editing the Request Access email address, disables the one-click Request Access helper once `request-access` exists, and prevents duplicate slugs in both the Admin Settings modal and create API.
+
+Version `0.242.040` changed navigation rendering so Custom Pages appears for any signed-in user only when `custom_pages_nav` contains at least one enabled, visible, authorized page. This allows `access_level=authenticated` pages such as Request Access to render for signed-in users without `User` or `Admin`, while hiding the pane when no custom page is available.
+
+## Usage Instructions
+
+Admins can open Admin Settings > Custom Pages to enable the feature and create metadata for simple static pages. Metadata references files already deployed under `application/single_app/custom_pages/html`, `css`, `js`, `assets`, and `json`.
+
+For CSS, JavaScript, asset, and JSON references, admins add one file at a time using the Add button in the metadata designer. The backend still persists those values as arrays in the `custom_pages` Cosmos container.
+
+When Allowed Roles is blank, any signed-in app user can access the custom page. When Allowed Roles has values, users must have at least one matching role in the current session. `Admin` satisfies `User`, but `Admin` does not satisfy arbitrary custom roles. Unknown role names do not grant access.
+
+Access Level controls the base gate before page-specific roles are checked. `App users only` requires `User` or `Admin`. `Any signed-in user` requires login but does not require the base app role, and is intended for bootstrap pages such as Request Access.
+
+When enabled, authorized pages appear in top and left navigation between Chat and the Support/External Links area. When disabled, `/custom` routes return Not Found before metadata lookup, file access, or Python extension dispatch.
+
+When Custom Pages is enabled but no custom page metadata or Python-backed pages are available, the navigation still shows the Custom Pages section with a `No custom pages registered` empty state.
+
+When an admin enables Custom Pages from a disabled state, the Admin Settings UI displays a restart acknowledgement modal. The setting is only accepted after acknowledgement, and the successful save writes an activity log record because App Service restart is required before newly deployed custom page files and Python-backed pages are fully active.
+
+## Example Pages
+
+The repository includes three deployment-time examples:
+
+- `example-simple.html`: A minimal HTML fragment that only needs metadata in the Admin Settings designer.
+- `example-static.html`, `example-static.css`, and `example-static.js`: A static page with page-specific CSS and JavaScript.
+- `example_python_dashboard.py`: A Python-backed page that renders `example-python-dashboard.html` as a Jinja template and exposes `/api/custom/example-python-dashboard/status` through the host dispatcher.
+
+The Python-backed example is discovered from code, so it should not be created in the metadata designer. Static examples are stored in Cosmos through the designer.
+
+## Testing and Validation
+
+Functional coverage was added in `functional_tests/test_custom_pages_wiring.py`. It validates version/configuration wiring, protected route registration, Admin Settings UI wiring, navigation integration, and the trusted HTML rendering boundary without requiring live Cosmos DB connectivity.
+
+Known limitations:
+
+- The Admin Settings designer manages metadata only; app teams still deploy the referenced files as part of the application artifact.
+- Python-backed pages are trusted deployment-time extensions, not arbitrary runtime code uploaded by users.

+# Data Management Backup and Migration
+
+Implemented in version: **0.241.211**
+Updated in version: **0.241.221**
+
+## Overview
+
+The Data Management feature adds an admin-only portal section for SimpleChat-owned backup, restore preparation, and migration orchestration. It stores its configuration as a separate `backup_settings` document in the Cosmos `settings` container rather than mixing backup secrets and schedules into normal app settings.
+
+## Technical Specifications
+
+### Architecture
+
+- Admin API routes live in `route_backend_data_management.py` and require `@swagger_route(security=get_auth_security())`, `@login_required`, and `@admin_required` on every endpoint.
+- Settings, scheduler logic, encryption-key handling, job leasing, and backup artifact creation live in `functions_data_management.py`.
+- Job records are stored in the `data_management_jobs` Cosmos container with partition key `/id`.
+- Job timeline entries are stored in the `data_management_job_items` Cosmos container with partition key `/job_id`.
+- Data Management job lifecycle events are also written to the shared `activity_logs` container with `activity_type` set to `data_management`, allowing Control Center Activity Logs to filter and search backup job activity by job ID, operation, backup type, and status.
+- Scheduled scans use the existing distributed background task lease pattern with the `data_management_scheduler_scan` lock.
+
+### Backup Artifacts
+
+Backup jobs write JSON/JSONL artifacts to the configured Azure Blob Storage container:
+
+- Cosmos DB app data for settings, users/groups/workspaces, conversations, documents, agents, actions, prompts, and workspace identities.
+- AI Search schemas and retrievable index documents for personal, group, and public indexes.
+- Optional source document blob backup can be enabled from the admin UI.
+- A manifest records artifact paths, app version, backup type, encryption status, and warnings.
+
+### Job History and Backup Inventory
+
+The Data Management tab shows two complementary historical views:
+
+- **Backup Inventory** leads with available backups, then full and partial backup filters. The inventory table summarizes completed jobs by backup identity, contents, storage/manifest state, protection, warning count, and a View Log action.
+- **Job History** lists recent Data Management jobs with status, progress, message, and a View Log action. The detail modal shows a live progress bar while queued or running, then structured sections for timeline events, backup contents, storage/manifest details, and warnings.
+- **Advanced Backup Scope** lives inside the Schedule card as a collapsed drawer. It includes the Cosmos DB, AI Search index, and source document blob backup switches with explicit risk guidance because excluding a surface can create incomplete backups for restore or migration.
+
+Full backup details focus on the full snapshot contents: Cosmos containers exported, AI Search schemas/documents exported, optional source blob containers, artifact sizes, item/blob counts, encryption status, manifest location, and warnings.
+
+Partial backup details use the same artifact layout but also expose the partial selection metadata, including Cosmos `_ts` lower-bound epochs and AI Search date filters where available. This makes it possible to understand what changed since the previous full or partial backup window.
+
+### Migration Workflow
+
+The Migration card supports a guided migration workflow:
+
+- Configure Target Cosmos DB, Target Search, and Target Enhanced Citation Storage, with test buttons for each target service.
+- Select whether to migrate no users, all users, or selected users, with optional user document migration.
+- Select whether to migrate no groups, all groups, or selected groups, with optional group document migration.
+- Select whether to migrate no public workspaces, all public workspaces, or selected public workspaces, with optional public workspace document migration.
+- Preview the migration plan to refresh counts and selected IDs before execution.
+- Execute Migration queues a durable Data Management migration job. The job history modal shows live progress, per-step timeline events, migrated artifact counts, and warnings.
+
+Migration execution currently copies selected SimpleChat Cosmos records, matching AI Search documents for selected document scopes, and source document blobs when Enhanced Citations source and destination storage are configured.
+
+### Security
+
+- All Data Management routes are admin-only.
+- Backup storage connection strings, target Cosmos keys, and encryption key references are redacted before being returned to the browser.
+- The admin JavaScript uses DOM creation and `textContent` for API-returned job data.
+- Browser runtime JavaScript is served from the local SimpleChat static path: `static/js/admin/admin_data_management.js`.
+- Encryption uses a generated 256-bit Fernet key. When Key Vault secret storage is available, the key is stored there under the `backup` source; otherwise it is stored in the separate backup settings document.
+
+### Configuration Options
+
+- Scheduled backup enablement.
+- Full backup frequency: daily, weekly, every 14 days, or every 30 days.
+- Partial backups: daily only.
+- Default scheduled time: `03:00` UTC.
+- Backup storage authentication: managed identity or connection string.
+- Managed identity storage shows the Blob endpoint field.
+- Connection string storage shows the connection string field and indicates when a redacted connection string is already saved.
+- Backup storage must use a dedicated Azure Storage account. Data Management rejects backup settings or storage tests that match the Enhanced Citations storage connection string or normalized Blob endpoint.
+- Source document blob backup is available only when Enhanced Citations is enabled. It defaults on when available and is disabled when Enhanced Citations is off.
+- Backup encryption keys can be stored in Key Vault when Key Vault secret storage is enabled. If Key Vault is unavailable, generated keys fall back to the Data Management settings document and the admin UI recommends enabling Key Vault.
+- Target Cosmos authentication: managed identity or account key.
+- Target Cosmos database name: always `SimpleChat`.
+- Target Search authentication: managed identity or admin key.
+- Target Enhanced Citation Storage authentication: managed identity or connection string.
+- Backup scope toggles for Cosmos DB, AI Search, and source document blobs.
+
+The admin portal groups schedule, storage, and encryption controls under a parent **Backup** card. Migration settings are grouped under a separate **Migration** card with an inner **Target Cosmos Database** card.
+
+Data Management settings save through their own API and are excluded from the regular Admin Settings floating Save button. The Data Management Save Settings button is disabled and labeled `Saved` until one of the Data Management controls changes.
+
+## Usage Instructions
+
+1. Open Admin Settings and select the top-level Data Management tab.
+2. Configure backup storage using managed identity or a storage connection string.
+3. Use Test Storage to validate and create the backup container if needed.
+4. Generate an encryption key or let the first encrypted backup generate one automatically.
+5. Configure the full backup cadence and scheduled UTC time.
+6. Queue a full or partial backup, or use the restore/migration dry-run buttons to create durable orchestration records.
+7. Configure and test Target Cosmos, Target Search, and Target Enhanced Citation Storage before running an actual migration.
+8. Use the Migration Workflow to choose users, groups, and public workspaces, then decide whether documents, AI Search entries, and source blobs should be included.
+9. Preview the migration plan, then Execute Migration to queue the job.
+10. Open Advanced backup scope only when you need to alter the default Cosmos DB, AI Search index, or source blob backup surfaces.
+11. Use Backup Inventory to see available backups first, filter to full or partial backups, and open View Log for structured backup details.
+12. Use Job History to inspect live progress, completed steps, warnings, storage/manifest details, and artifact contents for any Data Management job.
+
+Migration is used when moving SimpleChat data into another SimpleChat environment, rehearsing a cutover, or preparing a controlled environment transfer. The target Cosmos account, authentication type, and optional account key are configurable. The target database name is fixed to `SimpleChat` so future migration apply jobs use the standard SimpleChat container layout.
+
+For managed identity target Cosmos migration, assign this App Service identity Cosmos DB Data Contributor on the target Cosmos account and ensure network access from the application environment.
+
+## Testing and Validation
+
+- Functional security coverage: `functional_tests/test_data_management_security_patterns.py`.
+- UI/template coverage: `ui_tests/test_admin_data_management_settings_ui.py`.
+- Syntax validation: `python -m py_compile` for modified backend modules and `node --check` for the admin browser module.
+
+## Limitations
+
+- Backup artifact export is implemented for Cosmos DB and AI Search, with optional source blob copying.
+- Restore and migration apply logic currently create durable admin job records and warnings; the target import/apply engine is the next implementation layer.
+
+## Version References
+
+- Application version updated in `application/single_app/config.py` to `0.241.221`.
+- Functional and UI tests include the same implementation version.

+# Document Intelligence PDF and Image Extraction Mode
+
+## Overview
+
+SimpleChat admins can choose how Azure Document Intelligence processes PDF and image uploads from the Search & Extract admin settings. The UI presents **Standard**, **Enhanced**, and **Auto** extraction modes. Standard maps to Azure Document Intelligence Read, and Enhanced maps to Azure Document Intelligence Layout.
+
+Implemented in version: **0.241.158**
+Enhanced in version: **0.241.163**
+UI terminology updated in version: **0.241.166**
+Extraction action terminology updated in version: **0.241.167**
+
+## Purpose
+
+The setting lets administrators balance extraction speed against richer document understanding:
+
+- **Standard** keeps the previous Read behavior and focuses on faster OCR text extraction.
+- **Enhanced** uses Layout to capture richer document structure for PDFs and images, including tables, layout structure, forms, and checked or unchecked selection marks. Enhanced can add parsing latency compared with Standard and has a 6X increase for every 1000 pages when selected.
+- **Auto** samples the configured number of first PDF pages with Enhanced extraction. If the sample shows table structure or selection marks, the full PDF is extracted with Enhanced. Otherwise, SimpleChat finishes extraction with Standard. Images use Enhanced in Auto mode because they are single-page inputs and benefit from spatial structure detection.
+
+## Technical Specifications
+
+- Setting key: `document_intelligence_pdf_image_extraction_mode`
+- Allowed values: `read`, `layout`, `auto`
+- Default value: `read`
+- Auto sample-page key: `document_intelligence_auto_sample_pages`
+- Auto sample-page default: `3`
+- Document metadata key: `document_intelligence_extraction_mode`
+- Requested mode metadata key: `document_intelligence_extraction_mode_requested`
+- Auto reason metadata key: `document_intelligence_auto_reason`
+- Applies to PDF and image uploads handled through Azure Document Intelligence.
+- Enhanced/Layout extraction requests Markdown output so table and selection mark structure can be preserved in page content for search and chat retrieval.
+- New PDF and image uploads store the original source blob even when enhanced citations are disabled. This makes later PDF extraction changes possible without requiring enhanced citations.
+
+## File Structure
+
+- `application/single_app/functions_settings.py`: default value and normalization helpers.
+- `application/single_app/templates/admin_settings.html`: Search & Extract admin selector.
+- `application/single_app/static/js/admin/admin_settings.js`: connection test payload and admin change hook.
+- `application/single_app/route_backend_settings.py`: mode-aware Document Intelligence connection test.
+- `application/single_app/functions_content.py`: mode-aware Azure Document Intelligence extraction.
+- `application/single_app/functions_documents.py`: PDF/image metadata update and ingestion call.
+- `application/single_app/route_backend_documents.py`: personal PDF extraction change API.
+- `application/single_app/route_backend_group_documents.py`: group PDF extraction change API.
+- `application/single_app/route_backend_public_documents.py`: public workspace PDF extraction change API.
+- `application/single_app/static/js/workspace/workspace-documents.js`: personal workspace extraction badges and Change Extraction actions.
+- `application/single_app/static/js/workspace/workspace-tags.js`: personal folder extraction badges and Change Extraction actions.
+- `application/single_app/templates/group_workspaces.html`: group workspace extraction badges and Change Extraction actions.
+- `application/single_app/static/js/public/public_workspace.js`: public workspace extraction badges and Change Extraction actions.
+
+## Usage
+
+1. Open Admin Settings.
+2. Go to Search & Extract.
+3. In Document Intelligence, choose **Standard**, **Enhanced**, or **Auto** for PDF and image extraction.
+4. If choosing Auto, set how many first PDF pages to sample.
+5. Save settings.
+
+New PDF and image uploads record both the requested extraction mode and the resolved Standard/Enhanced mode in document metadata. Existing documents with missing extraction metadata are treated as **Standard** in workspace file info.
+
+Workspace users with document management permission can use **Change Extraction** from the document ellipsis menu or the multi-select toolbar. Single-document actions only show the opposite extraction mode: Standard documents offer **Change to Enhanced**, and Enhanced documents offer **Change to Standard**. The menu item tooltip explains when the target mode is useful. Older PDFs that do not have a stored source blob must be re-uploaded before extraction can be changed.
+
+## Testing and Validation
+
+Functional coverage is provided by `functional_tests/test_document_intelligence_pdf_image_extraction_mode.py` and `functional_tests/test_document_intelligence_auto_reprocess_contract.py`.
+
+UI contract coverage is provided by `ui_tests/test_document_intelligence_extraction_ui_contract.py`.
+
+Config version updated in `application/single_app/config.py` to `0.241.167`.

+# File Sync Admin Management
+
+Fixed/Implemented in version: **0.241.069**
+Workspace assignment gates implemented in version: **0.241.180**
+
+## Overview
+
+File Sync administration has a dedicated Admin Settings tab for configuring synchronization across personal, group, and public workspaces. The tab separates global sync limits from per-scope access gates and gives SimpleChat admins a way to manage sync sources on behalf of users, groups, and public workspaces.
+
+## Purpose
+
+This feature makes File Sync easier to discover and safer to operate at scale. Admins can enable File Sync per workspace scope, require the PersonalFileSyncUser app role for personal sync, assign specific groups or public workspaces for shared-workspace sync, and decide whether workspace managers can manage their own sources or whether source management is restricted to SimpleChat admins.
+
+## Dependencies
+
+- Redis Cache must be enabled and configured before File Sync is effectively active.
+- SMB source connections use the existing File Sync SMB support.
+- Group and public workspace source management requires existing workspace records.
+- The `PersonalFileSyncUser` app role must be created on the SimpleChat app registration before enabling the personal require-role toggle.
+- Group and public workspace File Sync access is controlled by Admin Settings assignment lists, not group/public app roles.
+- Version was updated in `application/single_app/config.py` to `0.241.180` for workspace assignment gates.
+
+## Technical Specifications
+
+### Architecture
+
+- Admin Settings now includes a top-level File Sync tab instead of embedding File Sync under Workspaces.
+- The File Sync settings model uses a personal app-role requirement and group/public workspace assignment gates:
+  - `file_sync_personal_require_app_role`
+  - `require_group_assignment_for_file_sync`
+  - `file_sync_allowed_group_ids`
+  - `require_public_workspace_assignment_for_file_sync`
+  - `file_sync_allowed_public_workspace_ids`
+- Local allow-list and blocklist settings are no longer enforced or rendered in the File Sync admin UI.
+- The only active File Sync app role value is `PersonalFileSyncUser`.
+- New admin-only management flags control whether self-service workspace source management is available:
+  - `file_sync_personal_admin_only`
+  - `file_sync_group_admin_only`
+  - `file_sync_public_admin_only`
+- Scheduled File Sync runs for group and public workspace sources are skipped when the corresponding assignment requirement is enabled and the source workspace is no longer assigned.
+
+### API Endpoints
+
+Admin target search endpoints:
+
+- `GET /api/admin/file-sync/users/search`
+- `GET /api/admin/file-sync/groups/search`
+- `GET /api/admin/file-sync/public-workspaces/search`
+
+Admin-managed source endpoints:
+
+- `/api/admin/file-sync/personal/<target_user_id>/sources`
+- `/api/admin/file-sync/group/<group_id>/sources`
+- `/api/admin/file-sync/public/<public_workspace_id>/sources`
+
+Each admin source API supports the same source list, create, update, delete, test connection, sync now, and run history workflows used by the workspace File Sync UI.
+
+### File Structure
+
+- `application/single_app/functions_file_sync.py`: File Sync config normalization, personal app-role checks, workspace assignment checks, scheduled-run assignment filtering, and admin-only management gating.
+- `application/single_app/route_backend_file_sync.py`: admin target search and admin-managed source APIs.
+- `application/single_app/templates/admin_settings.html`: dedicated File Sync tab, per-scope cards, assignment modals, target manager modal.
+- `application/single_app/static/js/admin/admin_settings.js`: assignment list modals, target search, and admin source manager modal wiring.
+- `application/single_app/static/js/workspace/workspace-file-sync.js`: reusable source manager initializer.
+
+## Usage Instructions
+
+1. Open Admin Settings and select File Sync.
+2. Enable File Sync globally after Redis Cache is configured.
+3. Enable the desired scopes: Personal, Group, and/or Public.
+4. Create and assign `PersonalFileSyncUser` before enabling the personal require-role toggle.
+5. For group File Sync, enable Require Group Assignment to Use File Sync and choose groups with Manage Groups.
+6. For public workspace File Sync, enable Require Public Workspace Assignment to Use File Sync and choose public workspaces with Manage Public Workspaces.
+7. Turn on admins-only source management for any scope that should be centrally managed.
+8. Use the Manage Sources controls to search for a target and open the source manager modal.
+
+## Testing and Validation
+
+Coverage was updated in:
+
+- `functional_tests/test_file_sync_capability.py`
+- `ui_tests/test_workspace_file_sync_ui.py`
+- `ui_tests/test_admin_file_sync_settings_ui.py`
+
+Validation covers the dedicated admin tab, personal app-role UI, group/public assignment UI, removal of local allow-list and blocklist wiring, admin target search endpoints, admin source management endpoints, scheduled-run assignment filtering, and reusable source manager initialization.
+
+## Known Limitations
+
+- Personal admin source management targets users by user ID. The target search picker fills this automatically.
+- Admin-managed personal sources do not create or validate the user's profile record; they use the selected user ID as the File Sync scope.
+- Existing stored allow-list and blocklist values may remain in persisted settings data but no longer affect File Sync authorization.

+# File Sync Recursive Source Controls
+
+Implemented in version: **0.241.056**
+
+Fixed/Implemented in version: **0.241.056**
+
+## Overview
+
+File Sync source management now supports explicit recursive folder control, SMB connection testing before save, and a more structured source form for selecting fixed tags. The application version was updated in `application/single_app/config.py` to track this feature work.
+
+## Dependencies
+
+- File Sync must be enabled by an administrator.
+- Redis Cache must be configured before sync runs are effective.
+- SMB sources require the `smbprotocol` package.
+- Directory user search in Admin Settings uses Microsoft Graph access already used by SimpleChat directory user helpers.
+
+## Technical Specifications
+
+- Administrators can allow or disable recursive File Sync sources with `file_sync_allow_recursive_sources`.
+- Each source stores a `recursive` boolean. When disabled, the SMB scanner reads only files directly under the configured UNC path.
+- Folder-derived tags continue to use each file's relative path from the configured UNC root, so parent folder mode tags the file's immediate containing folder rather than the root share path.
+- New connection-test endpoints validate UNC path and credentials without saving source changes.
+- The workspace source form fetches existing workspace tags and lets users select fixed tags as chips while still allowing new tag names.
+
+## File Structure
+
+- `application/single_app/functions_file_sync.py` - recursive source normalization, recursive-aware SMB walking, and SMB connection testing.
+- `application/single_app/route_backend_file_sync.py` - per-scope connection-test APIs and admin user search API.
+- `application/single_app/static/js/workspace/workspace-file-sync.js` - source form recursive switch, tag selector, schedule slider, and test connection button.
+- `application/single_app/templates/admin_settings.html` - recursive admin control and searchable user allow/block controls.
+- `application/single_app/static/js/admin/admin_settings.js` - admin user search, bulk add, and chip list behavior.
+
+## Usage Instructions
+
+Administrators enable File Sync and choose whether recursive sources are allowed. Workspace managers can then add or edit SMB sources, turn recursive scanning on or off per source, test connectivity before saving, select fixed tags, and choose whether missing remote files should be kept or deleted locally.
+
+## Testing and Validation
+
+- Functional coverage: `functional_tests/test_file_sync_capability.py`.
+- UI smoke coverage: `ui_tests/test_workspace_file_sync_ui.py`.
+- Source-level connection tests are intentionally shallow and check top-level directory access without walking the entire share.
+
+## Known Limitations
+
+- Connection testing validates access to the configured root path only; it does not guarantee every nested folder can be scanned.
+- Recursive scans can still hit max file, byte, and run limits configured by administrators.

+# File Sync Source Delete Options
+
+Implemented in version: **0.241.061**
+
+Fixed/Implemented in version: **0.241.061**
+
+## Overview
+
+File Sync source deletion now presents a modal choice instead of an inline confirmation. Workspace managers can delete only the sync source while keeping synced documents, or delete the synced documents before the source is removed.
+
+## Dependencies
+
+- File Sync must be enabled for the workspace scope.
+- Users must have the existing File Sync manager role for the workspace.
+- The version was updated in `application/single_app/config.py` for traceability.
+
+## Technical Specifications
+
+- The shared File Sync source table opens a Bootstrap modal with three choices: cancel, delete the source only, or delete all synced files with the source.
+- The source delete API accepts `delete_associated_files` in the JSON body.
+- Associated file deletion uses the existing synced document deletion helper so personal, group, and public workspace deletion behavior stays scoped correctly.
+- If associated document deletion fails, the source is not deleted and the API reports the failure.
+
+## File Structure
+
+- `application/single_app/static/js/workspace/workspace-file-sync.js` - source delete modal and delete choice payload.
+- `application/single_app/route_backend_file_sync.py` - delete request payload handling.
+- `application/single_app/functions_file_sync.py` - associated synced document deletion before source removal.
+- `functional_tests/test_file_sync_capability.py` - regression coverage for backend and UI wiring.
+- `ui_tests/test_workspace_file_sync_ui.py` - modal option smoke coverage.
+
+## Testing and Validation
+
+- `functional_tests/test_file_sync_capability.py` validates backend cascade wiring and modal text/options.
+- `ui_tests/test_workspace_file_sync_ui.py` validates the delete modal appears with both destructive choices.
+
+## Known Limitations
+
+- Associated file deletion relies on File Sync tracking items. Documents manually detached from File Sync metadata may not be included.
+- Delete all files removes SimpleChat documents only; it does not delete files from the remote SMB share.

+# File Sync Source Type Badges (v0.241.088)
+
+## Overview
+
+File Sync synced-document indicators now render as source-type badges instead of a generic synced label. SMB sources display an `SMB` badge, Azure Files sources display an `Azure Files` badge, and the mapping is ready for future connectors such as Microsoft 365 SharePoint, OneDrive, Google Workspace, and on-prem SharePoint.
+
+Implemented in version: **0.241.088**
+
+Related version update: `application/single_app/config.py` was incremented to `0.241.088` for this feature update.
+
+## Dependencies
+
+- Bootstrap badge classes and Bootstrap Icons.
+- Synced document metadata in `doc.file_sync`.
+- File Sync source metadata from `application/single_app/functions_file_sync.py`.
+
+## Technical Specifications
+
+### Architecture
+
+Synced document badges are driven by `doc.file_sync.source_type`. New File Sync documents persist `source_type` into the document metadata, and existing synced documents without this value fall back to `smb` so the UI remains backward compatible.
+
+### Badge Mapping
+
+| Source type | Badge label | Badge color |
+| --- | --- | --- |
+| `smb` | `SMB` | Primary |
+| `azure_files` | `Azure Files` | Info |
+| `m365sp` / `m365_sp` / `m365_sharepoint` / `sharepoint_online` | `M365SP` | Info |
+| `onedrive` / `one_drive` | `OneDrive` | Dark |
+| `google` / `google_workspace` | `Google` | Warning |
+| `spo` / `sharepoint_on_prem` | `SPO` | Success |
+
+Unknown source types render as uppercase labels with a secondary badge.
+
+### Files Updated
+
+- `application/single_app/functions_file_sync.py`
+- `application/single_app/static/js/workspace/workspace-utils.js`
+- `application/single_app/static/js/public/public_workspace.js`
+- `application/single_app/templates/group_workspaces.html`
+
+## Usage Instructions
+
+No administrator action is required. Synced files in personal, group, and public workspaces show the source-type badge anywhere the synced indicator is rendered.
+
+Future sync connectors should set `doc.file_sync.source_type` to one of the mapped values to receive the appropriate badge label and color.
+
+## Testing and Validation
+
+Coverage was updated in:
+
+- `functional_tests/test_file_sync_capability.py`
+- `functional_tests/test_file_sync_azure_files_identity.py`
+- `ui_tests/test_workspace_file_sync_ui.py`
+
+Validation checks confirm that synced document metadata includes `source_type`, the UI mapping includes current and planned source labels, and personal workspace UI tests expect the `SMB` badge instead of a generic synced badge.

+Implemented in version: **0.241.073**
+Azure Files source support implemented in: **0.241.127**
+OneDrive source support and selected-path workflow implemented in: **0.241.128**
+Global cloud drive connector identities implemented in: **0.241.129**
+Cloud connector admin visibility limited in: **0.241.178**
+
+Fixed/Implemented in version: **0.241.178**
+
+## Overview
+
+File Sync source creation and editing uses a modal workflow instead of an inline form. The first step selects the source type, and the second step configures the selected source. Admins can choose whether SMB Share and Azure Files source types are visible in the workflow. OneDrive, SharePoint, and Google Workspace controls remain visible in Admin Settings as coming soon while validation continues.
+
+## Dependencies
+
+- File Sync must be enabled for the current workspace scope.
+- Redis Cache must be configured before sync runs are effective.
+- SMB sources require the existing `smbprotocol` dependency.
+- Azure Files sources require the `azure-storage-file-share` dependency.
+- OneDrive source code remains in place for future validation and requires a global File Sync identity with Microsoft Graph application permissions when re-enabled.
+- Version was updated in `application/single_app/config.py` to `0.241.178` for the cloud connector admin visibility pause.
+
+## Technical Specifications
+
+- `workspace-file-sync.js` now renders a Bootstrap modal for add and edit source flows.
+- The workflow includes a Source Type step and a Configure step.
+- Admin Settings includes active `file_sync_visible_source_types` controls for SMB Share and Azure Files. OneDrive, On-prem SharePoint, and Google Workspace are disabled coming-soon controls and are not submitted with the admin settings form.
+- The source list table includes a Type column populated from each source's `source_type` field.
+- SMB payloads submit `source_type: "smb"`; Azure Files payloads submit `source_type: "azure_files"` with file service URL, share name, and optional directory path fields. OneDrive payload code remains in place but is not admin-enabled while the connector is paused.
+- The Configure step includes selected folders/files, Include subfolders, path patterns, file type filters, folder-derived tag behavior, and remote delete policy in a single selection and filters section.
+- Source browse APIs let the modal inspect provider folders and files before saving, then store selected paths in the source connection.
+- Cloud connector options are shown as coming soon in Admin Settings and are filtered out by server-side source visibility normalization even if submitted manually.
+- New source creation and unsaved connection tests reject source types hidden by the admin setting.
+
+## File Structure
+
+- `application/single_app/static/js/workspace/workspace-file-sync.js` - shared modal workflow, source type selection, source type table column, and source-specific configuration forms.
+- `functional_tests/test_file_sync_onedrive_personal.py` - static coverage for OneDrive connector, selected paths, and browse route wiring.
+- `functional_tests/test_file_sync_azure_files_identity.py` - static coverage for Azure Files connector and identity wiring.
+- `functional_tests/test_file_sync_capability.py` - static coverage for workflow strings, source type payloads, and source type table wiring.
+- `ui_tests/test_workspace_file_sync_ui.py` - workspace smoke coverage for the source workflow modal.
+- `ui_tests/test_admin_file_sync_settings_ui.py` - admin-managed source workflow smoke coverage.
+
+## Usage Instructions
+
+Workspace managers click Add Source, choose SMB Share or Azure Files, and continue to Configure Source. Connection testing, selected folders/files, schedule settings, tag controls, recursive scanning, and remote-delete policy remain in the configuration step.
+
+## Testing and Validation
+
+- Functional coverage: `functional_tests/test_file_sync_capability.py`, `functional_tests/test_file_sync_azure_files_identity.py`, and `functional_tests/test_file_sync_onedrive_personal.py`.
+- UI smoke coverage: `ui_tests/test_workspace_file_sync_ui.py` and `ui_tests/test_admin_file_sync_settings_ui.py`.
+- JavaScript syntax coverage: `node --check application/single_app/static/js/workspace/workspace-file-sync.js`.
+
+## Known Limitations
+
+- OneDrive, On-prem SharePoint, and Google Workspace are temporarily unavailable from Admin Settings and are shown as coming soon.
+- Existing OneDrive code remains in place for future validation before re-enabling the connector.

+# Group Multi-User Participant Management
+
+Fixed/Implemented in version: **0.241.034**
+
+## Overview
+
+Group multi-user conversations now support the same explicit participant-management workflow as personal multi-user conversations. Group chats can be created or converted into invite-managed conversations, participants can be added through the existing picker modal, and conversation-level admins can be managed from the participant list.
+
+Dependencies:
+
+- `application/single_app/collaboration_models.py`
+- `application/single_app/functions_collaboration.py`
+- `application/single_app/route_backend_collaboration.py`
+- `application/single_app/static/js/chat/chat-collaboration.js`
+- `application/single_app/static/js/chat/chat-conversations.js`
+- `application/single_app/static/js/chat/chat-sidebar-conversations.js`
+
+Related config update: `application/single_app/config.py` now sets `VERSION = "0.241.034"`.
+
+## Technical Specifications
+
+Architecture overview:
+
+- New and converted group multi-user conversations use `scope.visibility_mode = 'invited_members'`.
+- Invited users must already be current members of the underlying group.
+- Legacy group collaborative conversations that still use `group_membership` remain readable through backward-compatible access checks.
+- Legacy group single-user conversations can now be converted through `/api/collaboration/conversations/from-group/<conversation_id>/members`.
+
+Configuration and file structure:
+
+- Group participant state is tracked with the same collaboration user-state documents used by personal multi-user conversations.
+- Group chat lists now serialize invite-managed membership state instead of assuming every group member has access.
+- The participant picker uses current group members as candidate results for eligible group conversations.
+
+## Usage Instructions
+
+How to use:
+
+- Create a new group multi-user conversation from a group context.
+- Add one or more current group members through the participant picker.
+- Promote accepted participants to conversation admins from the conversation details view when needed.
+- Convert an existing `group-single-user` conversation by adding participants; the system migrates the conversation into collaborative storage and copies the message history.
+
+Integration points:
+
+- Backend invite, role, leave, delete, pin, and hide routes reuse the collaboration APIs in `route_backend_collaboration.py`.
+- Frontend add-participant affordances are exposed from both the main conversation list and the sidebar.
+
+## Testing and Validation
+
+Test coverage:
+
+- `functional_tests/test_group_collaboration_participant_management.py`
+- `functional_tests/test_simplechat_group_multi_user_conversation.py`
+
+Validation notes:
+
+- Group invite validation rejects users who are not current group members.
+- Invite-managed group conversations no longer notify or expose access to every group member by default.
+
+Known limitations:
+
+- Legacy `group_membership` collaborative conversations are still supported for backward compatibility and may coexist with newer invite-managed group conversations.

+# Group And Public Workspace Custom Hero Colors
+
+Fixed/Implemented in version: **0.241.176**
+
+Related config.py version update: `application/single_app/config.py` is **0.241.176** for this implementation.
+
+## Overview
+
+Group and public workspace owners can brand workspace hero cards with either the existing preset swatches or a custom color swatch. The custom swatch uses the browser color picker and updates the live hero preview before saving.
+
+## Dependencies
+
+- Group workspaces or public workspaces enabled in Admin Settings
+- Owner or administrator permissions on the target workspace
+- Existing workspace branding manage pages
+
+## Screenshots
+
+### Group Workspace Custom Color
+
+The group manage page shows the custom swatch next to the preset colors and updates the hero preview immediately.
+
+<img src="{{ '/images/feature-group-custom-hero-color.png' | relative_url }}" alt="Annotated group workspace manage page showing custom hero color swatch and live hero preview." style="width: 80%;" />
+
+### Public Workspace Custom Color
+
+The public workspace manage page uses the same custom swatch behavior for public workspace branding.
+
+<img src="{{ '/images/feature-public-custom-hero-color.png' | relative_url }}" alt="Annotated public workspace manage page showing custom hero color swatch and live hero preview." style="width: 80%;" />
+
+## Technical Specifications
+
+Architecture overview:
+
+- Group and public workspace records continue to store a normalized `heroColor` value as a `#RRGGBB` string.
+- Existing logo upload flows remain unchanged and continue to store resized workspace logos as PNG data.
+- Manage pages expose a custom color input beside the preset swatches.
+- Client-side picker logic selects the custom swatch when a saved color does not match a preset.
+- Backend routes continue to validate custom colors through `normalize_workspace_hero_color()`.
+
+Files modified:
+
+- `application/single_app/templates/manage_group.html`
+- `application/single_app/templates/manage_public_workspace.html`
+- `application/single_app/static/js/group/manage_group.js`
+- `application/single_app/static/js/public/manage_public_workspace.js`
+- `functional_tests/test_workspace_branding_hero_and_logo.py`
+- `ui_tests/test_manage_group_page_branding.py`
+- `ui_tests/test_manage_public_workspace_page_load.py`
+
+## Usage Instructions
+
+Open a group or public workspace manage page as the owner. In the General tab, choose a preset hero color or use the custom swatch to pick any valid color. The hero preview updates immediately, and saving persists the chosen color with the rest of the workspace details.
+
+## Testing and Validation
+
+Test coverage:
+
+- Functional coverage verifies group and public manage pages include the custom swatch hooks and picker logic.
+- UI coverage verifies custom colors update the saved payload field and hero preview for group and public manage pages.
+
+Known limitations:
+
+- Custom colors are stored as solid hero base colors. The darker gradient stop is generated client-side from the selected color.

+# Group Workflows
+
+Implemented in version: **0.241.179**
+Enhanced in version: **0.241.193** for configurable workflow agent action limits.
+Enhanced in version: **0.241.194** with admin capacity guidance for high action limits.
+
+Fixed/Implemented in version: **0.241.193**
+
+Related version updates:
+- `application/single_app/config.py` reported version `0.241.179` when group workflows were implemented.
+- `application/single_app/config.py` reported version `0.241.193` for workflow action limit configuration.
+- `application/single_app/config.py` now reports version `0.241.194` for workflow action limit capacity guidance.
+
+## Overview
+
+Group Workflows extend the existing personal workflow system to group workspaces. A permitted group member can save repeatable tasks, run them manually, run them on an interval schedule, or trigger them after group File Sync changes.
+
+Dependencies:
+- `application/single_app/functions_group_workflows.py`
+- `application/single_app/functions_workflow_runner.py`
+- `application/single_app/route_backend_workflows.py`
+- `application/single_app/functions_settings.py`
+- `application/single_app/background_tasks.py`
+- `application/single_app/templates/group_workspaces.html`
+- `application/single_app/static/js/workspace/workspace_workflows.js`
+- `application/single_app/static/js/workflow/workflow-activity.js`
+
+## Technical Specifications
+
+Architecture overview:
+- Group workflow definitions are stored in the `group_workflows` Cosmos container partitioned by `group_id`.
+- Group workflow run history is stored in the `group_workflow_runs` Cosmos container partitioned by `group_id`.
+- Per-document run items are stored in the `group_workflow_run_items` Cosmos container partitioned by `run_id`.
+- The existing workflow runner is scope-aware and handles personal and group workflow execution through shared logic.
+- Group workflow conversations are created as hidden group conversations with `workspace_type='group'` and the active `group_id`.
+- Scheduled group workflows are picked up by the background scheduler through `get_due_group_workflows()` and assignment gating.
+
+API endpoints:
+- `GET /api/group/workflows`
+- `POST /api/group/workflows`
+- `GET /api/group/workflows/agents`
+- `GET /api/group/workflows/file-sync-sources`
+- `GET /api/group/workflows/<workflow_id>/runs`
+- `POST /api/group/workflows/<workflow_id>/run`
+- `POST /api/group/workflows/<workflow_id>/runs/<run_id>/resume-failed`
+- `DELETE /api/group/workflows/<workflow_id>`
+- `GET /api/group/workflows/activity`
+- `GET /api/group/workflows/activity/stream`
+
+Configuration options:
+- `allow_group_workflows` enables the group workflow feature.
+- `require_group_assignment_for_group_workflows` limits use to groups selected in the Admin Settings assignment modal.
+- `group_workflow_allowed_group_ids` stores the assigned group IDs.
+- `require_owner_for_group_agent_management` is now labeled as `Require Owner to Manage Group Agents, Actions and Workflows` and also governs group workflow authoring roles.
+- `enable_file_sync_group` gates group File Sync sources for workflow pre-run sync and File Sync monitor triggers.
+- `workflow_max_auto_invoke_attempts` controls the maximum automatic tool or action calls an agent can make during one workflow run and defaults to `60`.
+- Values above `100` should be treated as capacity-sensitive. Admins should enable Cosmos DB Throughput automation in SimpleChat so the app can monitor RU pressure and scale up Cosmos when needed, while also watching Azure OpenAI throttling, App Service CPU and memory, and downstream service latency.
+
+Permission model:
+- Runtime access is allowed for group Owners, Admins, Document Managers, and Users when the group workflow feature is enabled for that group.
+- Authoring and deletion are allowed for Owners and Admins by default.
+- When owner-only management is enabled, only Owners can create, update, or delete group workflows.
+- All group workflow API routes revalidate group membership and feature assignment before reading or mutating data.
+
+File Sync behavior:
+- Group workflows accept only group-scoped File Sync sources for the active group.
+- File Sync-triggered group workflows reuse the personal workflow run-item tracking and resume-failed behavior.
+- Changed files can be used as dynamic Analyze targets when the workflow File Sync configuration allows it.
+
+## Usage Instructions
+
+How to enable/configure:
+1. Open Admin Settings.
+2. Go to the Workspaces tab.
+3. Open the Workflow section.
+4. Enable `Enable Group Workflows`.
+5. Optionally enable `Require Group Assignment to Use Workflow` and choose groups with `Manage Groups`.
+6. Set `Workflow Agent Action Limit` when large group workflows need more than the default 60 automatic tool or action calls. For values above 100, enable Cosmos DB Throughput automation in SimpleChat and monitor service capacity.
+7. Optionally enable `Require Owner to Manage Group Agents, Actions and Workflows` to limit workflow authoring to group Owners.
+
+Group workflow:
+1. Open Group Workspaces.
+2. Select an active group.
+3. Open `Group Workflows`.
+4. Choose `New Group Workflow`.
+5. Enter a name, description, task prompt, runner, document action, alert priority, and trigger.
+6. Save and run the workflow manually, or let the scheduler run interval and File Sync monitor workflows.
+
+Integration points:
+- Group agents and merged global agents are available in the group workflow agent picker.
+- Group model endpoints and merged global endpoints are available for direct model workflows.
+- Group workflow activity links open the shared workflow activity page with `scope=group` and `group_id` context.
+
+## Testing And Validation
+
+Functional coverage:
+- `functional_tests/test_group_workflows_feature.py` verifies static contracts for storage, settings, routes, scheduler, runner scope, activity deep links, admin UI settings, and group workspace UI wiring.
+- `functional_tests/test_workflow_auto_invoke_attempt_settings.py` verifies workflow action limit defaults, admin save wiring, Semantic Kernel loader wiring, and workflow runner scoping.
+
+UI coverage:
+- `ui_tests/test_admin_workflow_settings_access.py` verifies the Admin Settings workflow section exposes the group workflow enablement, assignment, owner-only management controls, and workflow action limit control.
+
+Performance and limitations:
+- Group workflow runtime uses the same scheduler polling cadence and runner path as personal workflows.
+- Group workflow activity pages require the user to remain a member of the referenced group.
+- Group File Sync sources are available only when group File Sync is enabled for the active group.

+# Image Proposal Pipeline
+
+Implemented in version: **0.241.135**
+
+## Overview
+
+The image proposal pipeline lets models and agents suggest generated images inside normal chat responses without generating images automatically. Assistant output can include fenced `simpleimage` JSON blocks, which the chat frontend renders as opt-in approval cards. Users can approve, edit, or cancel each card, and messages with more than two pending cards show an approve-all control at the bottom of the assistant message.
+
+The feature uses the existing image generation model configuration and stores approved images in the chat-associated storage path before rendering them as normal chat image messages.
+
+## Dependencies
+
+- Image generation must be enabled in application settings.
+- Existing Azure OpenAI or APIM image generation configuration is reused.
+- Chat blob storage is used through the same generated chat image storage helper used for chat-associated artifacts.
+- Frontend rendering uses local static JavaScript modules only.
+
+## Technical Specifications
+
+### Model Proposal Schema
+
+Models and agents can emit proposals with fenced Markdown:
+
+````markdown
+```simpleimage
+{
+  "version": 1,
+  "visualId": "slide_09_timeline",
+  "title": "Timeline of major events, 1700-1750",
+  "description": "An illustrated timeline showing key early American events between 1700 and 1750.",
+  "prompt": "Create a horizontal illustrated timeline for 1700 to 1750 featuring key events with readable labels.",
+  "visualType": "timeline",
+  "slideNumber": 9,
+  "context": "Major events"
+}
+```
+````
+
+### Backend Components
+
+- `functions_image_generation.py`
+  - Builds image proposal model guidance.
+  - Normalizes image proposal payloads.
+  - Creates the configured image generation client.
+  - Generates and stores approved chat image messages.
+- `route_backend_chats.py`
+  - Adds image proposal guidance when image generation is enabled and the user asks for visual/slide/image-friendly content.
+  - Adds `POST /api/chat/image-proposals/generate` for user-approved generation.
+  - Authorizes personal chat access before generation.
+
+### Frontend Components
+
+- `static/js/chat/chat-inline-image-proposals.js`
+  - Extracts `simpleimage` blocks before Markdown sanitization.
+  - Injects inert placeholders into sanitized assistant HTML.
+  - Hydrates placeholders into approval cards after chat message masking/restoration.
+  - Calls the approval endpoint and appends the resulting image message.
+- `static/js/chat/chat-messages.js`
+  - Integrates image proposals with assistant rendering and final message hydration.
+- `static/js/chat/chat-streaming.js`
+  - Hydrates proposal cards during streaming, stopped-stream rendering, and error rendering.
+- `static/css/chats.css`
+  - Styles proposal cards, prompt editors, status text, and approve-all actions.
+
+## Usage Instructions
+
+1. Enable image generation in application settings.
+2. Ask for visual-friendly content such as slide visuals, timelines, diagrams, illustrations, maps, or infographics.
+3. When the assistant includes an image proposal card, choose one of the available actions:
+   - **Approve** generates and stores that image.
+   - **Edit** lets the user revise the image prompt before approval.
+   - **Cancel** dismisses the proposal.
+   - **Approve all image proposals** appears when a message has more than two pending proposal cards.
+
+## Testing and Validation
+
+- `functional_tests/test_image_proposal_pipeline.py` validates proposal normalization, guidance text, and settings gates.
+- `ui_tests/test_chat_inline_image_proposal_cards.py` validates card rendering, approve-all, edit, and cancel workflows with the approval endpoint mocked by Playwright.
+- Version was updated in `application/single_app/config.py` to `0.241.135` for traceability.
+
+## Known Limitations
+
+- The first implementation scopes approval to personal chat conversations because existing `/api/image/<image_id>` authorization is personal-conversation based.
+- Image generation remains opt-in in chat. Future agent setup workflows can add agent-level auto-allow controls without changing the card renderer or storage helper.

+# Inline Chart Color Editor
+
+Implemented in version: **0.241.145**
+
+Export override support added in version: **0.241.146**
+
+## Overview
+
+The inline chart color editor lets users adjust generated chart colors directly on a rendered chart without asking the model to create another version of the chart. It keeps the default chart card compact by hiding editing controls behind a small palette icon in the chart header.
+
+## Technical Specifications
+
+Files modified:
+
+- `application/single_app/static/js/chat/chat-inline-charts.js`
+- `application/single_app/static/css/chats.css`
+- `ui_tests/test_chat_inline_chart_rendering.py`
+- `application/single_app/config.py`
+
+Architecture:
+
+- Chart cards include a palette icon button with an on-demand color panel.
+- The panel provides curated palette presets and editable color inputs for chart series or the first visible slices in pie-style charts.
+- Color edits update the live Chart.js instance, the chart card `data-chart-spec`, and the hidden markdown textarea used by copy and client-side message export flows.
+- Per-message Word, PowerPoint, and email draft exports send the edited markdown from the current browser view so exported chart PNGs reflect color changes made in the chart editor.
+- The feature uses local Bootstrap Icons already available in the app and does not add any external browser assets.
+
+## Usage Instructions
+
+Open a chart's palette icon and choose a preset or adjust individual swatches. The chart updates in place, so users can tune a chart without adding extra assistant messages to the conversation.
+
+## Testing and Validation
+
+Test coverage:
+
+- `ui_tests/test_chat_inline_chart_rendering.py`
+
+Validation expectations:
+
+- The palette button is visible but compact in the chart header.
+- Opening the color panel exposes presets and swatches.
+- Editing a color updates the rendered Chart.js dataset and stored chart spec without creating another message.
+- Export requests include the edited assistant markdown so backend-rendered chart PNGs use the selected colors.
+
+Known limitation:
+
+- Browser-side color edits are not persisted back to the saved conversation record. Exports from the current page use the edited chart colors, but reloading the conversation restores the saved assistant message content.

+# Message Layered Masking
+
+Implemented in version: **0.241.098**
+
+Rendered Markdown selection masking updated in version: **0.250.029**
+
+## Overview
+
+Layered message masking lets users add multiple text masks to a chat message and independently apply or remove a full-message mask. This avoids the previous binary behavior where masking an already-masked message could only clear every mask.
+
+## Purpose
+
+Users can now progressively hide more content from future model context without losing existing selected-text masks. The behavior applies to personal conversations, group-context conversations, personal collaborative conversations, and group collaborative conversations.
+
+## Dependencies
+
+* `application/single_app/config.py` version `0.250.029`
+* Bootstrap Icons for mask action icons
+* Cosmos DB message metadata fields: `metadata.masked` and `metadata.masked_ranges`
+* Collaboration event stream for shared conversation updates
+
+## Technical Specifications
+
+### Architecture
+
+Mask state is managed as two independent layers:
+
+* Full-message mask: `metadata.masked`, `metadata.masked_by_user_id`, `metadata.masked_timestamp`, and `metadata.masked_by_display_name`
+* Text-range masks: `metadata.masked_ranges`, with canonical `start`, `end`, `text`, user, timestamp values, and optional rendered-display offsets for browser highlighting
+
+The shared masking logic lives in `functions_message_masking.py`. It validates selection offsets against stored message content, falls back only when selected text is unique, maps rendered Markdown selections back to canonical stored content for formatted messages, merges overlapping ranges, and preserves selected ranges when the full-message mask is removed.
+
+### API Endpoints
+
+* `POST /api/message/<message_id>/mask`
+* `POST /api/collaboration/conversations/<conversation_id>/messages/<message_id>/mask`
+
+Supported actions:
+
+* `mask_all`: applies a full-message mask without clearing selected ranges
+* `mask_selection`: adds and merges a selected text range
+* `unmask_message`: removes only the full-message mask
+* `clear_all_masks`: clears both full-message and selected-range masks
+* `unmask_all`: legacy destructive clear-all behavior
+
+The backend derives mask user identity from the authenticated session. The browser does not send `user_id` or `display_name` in masking payloads.
+
+### Collaboration Sync
+
+Collaborative message masking updates the collaboration message metadata and syncs mask metadata to linked source messages. This keeps shared UI state and future AI conversation history aligned for personal and group collaborative conversations.
+
+The collaboration event stream publishes `collaboration.message.masked`, allowing visible shared messages to update without requiring a page reload.
+
+## Usage Instructions
+
+Use the mask button on a message footer:
+
+* Select text and press the mask-plus control to add a text mask.
+* Press the mask-plus control without a selection to apply a full-message mask.
+* Press the mask-minus control while a full-message mask is active to remove only that full-message layer and preserve selected text masks.
+* Press the mask-minus control when only selected text masks remain to clear those text masks.
+
+## File Structure
+
+* `application/single_app/functions_message_masking.py`
+* `application/single_app/route_backend_chats.py`
+* `application/single_app/route_backend_collaboration.py`
+* `application/single_app/static/js/chat/chat-messages.js`
+* `application/single_app/static/js/chat/chat-collaboration.js`
+* `application/single_app/static/css/styles.css`
+* `functional_tests/test_chat_layered_message_masking.py`
+* `ui_tests/test_chat_message_layered_mask_controls.py`
+
+## Testing and Validation
+
+Coverage includes:
+
+* Additive selected-text masking and range merging
+* Full-message mask removal that preserves selected text masks
+* Canonical stored-content validation for selected ranges
+* Rendered Markdown selection mapping for formatted text and Markdown tables
+* Browser control rendering for mask-plus and mask-minus buttons
+* Collaboration mask endpoint routing and event-driven UI updates
+
+Known limitation: individual selected ranges are merged when adjacent or overlapping, so clearing one specific sub-range is not yet exposed as a separate UI action.
+
+## Version Tracking

+# Microsoft Graph Pending Actions
+
+Implemented in version: **0.241.179**
+
+## Overview
+
+Microsoft Graph mail sends and calendar invite creation can now run in three delivery modes: manual review, delayed send, or auto-send. Manual and delayed modes create a user-owned pending action so the chat and workflow activity views can show review controls, countdowns, consent prompts, and terminal status without exposing stored Graph request payloads to the browser.
+
+The Microsoft Graph action configuration nests delivery options directly under the related capability. Enabling **Send mail** exposes the email delivery mode and delayed-send slider. Enabling **Create calendar invites** exposes the calendar invite delivery mode and delayed-send slider.
+
+## Dependencies
+
+- Microsoft Graph delegated permissions through the signed-in user.
+- Cosmos DB container `msgraph_pending_actions`, partitioned by `/user_id`.
+- Existing Microsoft Graph plugin configuration and agent citation flow.
+
+## Technical Specifications
+
+### Architecture
+
+- `functions_msgraph_pending_actions.py` stores, sanitizes, approves, cancels, and auto-commits pending Microsoft Graph actions.
+- `route_backend_msgraph_pending_actions.py` exposes user-scoped API routes for listing, status lookup, send-now, approve, and cancel operations.
+- `semantic_kernel_plugins/msgraph_plugin.py` creates pending actions for manual or delayed mail/calendar operations and returns sanitized `pending_action` metadata in plugin results.
+- `functions_workflow_activity.py` merges pending Microsoft Graph actions into workflow activity snapshots.
+- `chat-messages.js` and `workflow-activity.js` render send/cancel controls and countdowns from sanitized pending action metadata.
+- Consent or interactive-auth errors render a friendly Microsoft 365 grant-access card for Outlook email, Calendar, OneDrive, and SharePoint access. The card opens the generated Microsoft identity prompt in a popup, then offers a test-access button that verifies silent access after consent and clears the prompt.
+
+### API Endpoints
+
+- `GET /api/msgraph/pending-actions`
+- `GET /api/msgraph/pending-actions/<action_id>`
+- `POST /api/msgraph/pending-actions/<action_id>/approve`
+- `POST /api/msgraph/pending-actions/<action_id>/send-now`
+- `POST /api/msgraph/pending-actions/<action_id>/cancel`
+- `POST /api/msgraph/test-access`
+
+### Configuration
+
+Microsoft Graph plugin settings support:
+
+- `msgraph_mail_send_mode`: `draft_manual`, `draft_delayed`, or `auto_send`.
+- `msgraph_mail_delay_seconds`: 5 to 600 seconds.
+- `msgraph_calendar_send_mode`: `draft_manual`, `draft_delayed`, or `auto_send`.
+- `msgraph_calendar_delay_seconds`: 5 to 600 seconds.
+
+Calendar invite delivery defaults to `auto_send` to preserve existing behavior.
+
+## Usage Instructions
+
+Configure a Microsoft Graph action in the workspace action modal, enable the required mail or calendar capability, and choose the nested delivery mode. For delayed delivery, use the 5 to 600 second slider under the capability. When an agent uses manual or delayed delivery, the chat response shows a pending action card. Workflow activity also shows a Microsoft 365 activity row for the pending mail or calendar action.
+
+Delayed actions show a countdown and can be sent immediately or cancelled before the timer completes. Manual actions wait for the user to send or cancel them.
+
+## Testing and Validation
+
+- `functional_tests/test_msgraph_plugin_operations.py` validates plugin-level pending mail behavior.
+- `functional_tests/test_msgraph_pending_actions.py` validates helper-layer send, cancel, sanitization, and filtering behavior.
+- `functional_tests/test_msgraph_access_test_route.py` validates post-consent access checks and unsupported scope rejection.
+- `functional_tests/test_workflow_activity_view_feature.py` validates workflow activity snapshot rows for pending Graph actions.
+- `ui_tests/test_workspace_msgraph_action_modal.py` validates the Microsoft Graph modal nested mail/calendar delivery sliders when Playwright is available.
+- `ui_tests/test_chat_inline_export_action_buttons.py` validates that Graph pending and Microsoft 365 consent contexts suppress the generic local email button.
+
+Known limitations:
+
+- Delayed auto-send uses an in-process timer with the current delegated token for the configured 5 to 600 second window. A future durable scheduler would be needed for restart-proof delayed delivery.
+- Workflow activity now shows and controls pending Graph actions, but the workflow runner is not yet a durable resumable dependency graph. A future workflow orchestration change would be needed to pause and resume dependent branches while allowing independent branches to continue.

+# Microsoft Graph Send Mail Action
+
+Fixed/Implemented in version: **0.241.179**
+
+Related config.py version update: `application/single_app/config.py` is **0.241.179** for this implementation.
+
+## Overview
+
+The Microsoft Graph action can now create or send email from the signed-in user's mailbox. The action supports manual drafts, delayed-delivery drafts, and automatic sends while keeping configuration scoped to the existing Microsoft Graph action setup.
+
+From the action configuration point of view, users add or edit a Microsoft Graph action from the normal action modal, enable the `Send mail` capability, and choose how mail should be delivered before assigning that action to agents.
+
+## User Experience
+
+### Add or Open a Microsoft Graph Action
+
+Open **Personal Workspace** or another action management surface, go to **Actions**, and choose **New Action**. Select **Microsoft Graph** to use the built-in delegated Graph action.
+
+<img src="{{ '/images/feature-msgraph-action-selection.png' | relative_url }}" alt="Annotated Add Action modal showing the Microsoft Graph action type selection." style="width: 70%;" />
+
+### Configure Send Mail
+
+In the Microsoft Graph configuration step, leave **Send mail** enabled when agents should be able to create drafts or send email. Use the delivery controls nested under **Send mail** to choose the default send behavior for this action.
+
+<img src="{{ '/images/feature-msgraph-mail-delivery.png' | relative_url }}" alt="Annotated Microsoft Graph configuration showing the Send mail capability and nested delivery settings." style="width: 70%;" />
+
+## Dependencies
+
+- Microsoft Graph delegated user tokens
+- `Mail.ReadWrite` for draft creation
+- `Mail.Send` for automatic send and delayed draft submission
+- Existing SimpleChat Microsoft Graph action configuration
+
+## Technical Specifications
+
+- Capability key: `send_mail`
+- Runtime function: `MSGraphPlugin.send_mail`
+- Configuration fields:
+  - `additionalFields.msgraph_mail_send_mode`
+  - `additionalFields.msgraph_mail_delay_seconds`
+- Supported send modes:
+  - `draft_manual`
+  - `draft_delayed`
+  - `auto_send`
+- Delayed delivery range: 5 to 600 seconds
+
+## Usage Instructions
+
+Configure a Microsoft Graph action from the action plugin modal and enable the `Send mail` capability. Choose the mail delivery mode directly under the capability. For delayed delivery, set a delay from 5 seconds to 600 seconds with the slider.
+
+Supported delivery choices:
+
+- **Draft with manual send** creates a draft so the user can review and send it manually.
+- **Draft with delayed send** creates and submits a delayed-send draft using the configured delay.
+- **Auto send** sends the message automatically from the signed-in user's mailbox.
+
+## Testing and Validation
+
+- Functional test coverage: `functional_tests/test_msgraph_plugin_operations.py`
+- Runtime overlay coverage: `functional_tests/test_msgraph_agent_action.py`
+- Version reference updated in `application/single_app/config.py`
+
+## Known Limitations
+
+Delayed delivery relies on Microsoft Graph creating a message draft with Outlook's deferred-delivery extended property before submitting the draft. Final delivery behavior is governed by Exchange and Outlook mailbox processing.

+# OneDrive File Sync
+
+Implemented in version: **0.241.128**
+Global connector identity management updated in version: **0.241.129**
+
+## Overview
+
+OneDrive File Sync adds a personal-workspace source type for pulling files from a user's OneDrive into SimpleChat's existing document processing and Azure AI Search indexing pipeline. The sync is one-way from OneDrive into SimpleChat.
+
+## Dependencies
+
+- Microsoft Graph application permissions for file access, such as `Files.Read.All`, granted to an admin-managed global File Sync identity.
+- Existing File Sync prerequisites, including enabled File Sync settings and Redis readiness.
+- Existing document processing services for extraction, chunking, embeddings, and indexing.
+
+## Technical Specifications
+
+- Source type: `onedrive`.
+- Scope: personal workspaces only. Group and public workspace source creation is rejected for OneDrive.
+- Authentication: Microsoft Graph application token acquired from an admin-managed global File Sync identity with client-secret credentials. Existing app registration configuration remains as an upgrade fallback.
+- Change state: OneDrive drive item IDs are used for stable remote identity, and Graph `eTag`/`cTag` values are stored as remote change tokens before content checksum fallback.
+- Content handling: changed files are downloaded to a temporary file, hashed with SHA-256, and passed through `process_document_upload_background()` like SMB and Azure Files sources.
+- Metadata: synced documents keep `file_sync` metadata including source type, relative path, remote size, remote modified time, remote change token, content hash, and web URL when available.
+
+## File Structure
+
+- `application/single_app/functions_file_sync.py` - OneDrive provider helpers, selected path normalization, browse support, and provider dispatch.
+- `application/single_app/route_backend_file_sync.py` - source browse APIs for creating and editing sync sources.
+- `application/single_app/static/js/workspace/workspace-file-sync.js` - personal-only OneDrive source option, selected folders/files UX, browse modal, and moved include-subfolders control.
+- `application/single_app/templates/admin_settings.html` - OneDrive source visibility control.
+- `functional_tests/test_file_sync_onedrive_personal.py` - static regression coverage.
+
+## Usage Instructions
+
+1. Ensure File Sync is enabled and Redis is configured.
+2. In Admin Settings, create a global workspace identity for File Sync using client-secret authentication and grant that app registration Microsoft Graph application file permissions.
+3. In a personal workspace, open Sync, add a source, and choose OneDrive.
+4. Leave selected folders/files empty to sync the OneDrive root, or browse/add specific folders and files.
+5. Use Include subfolders to control recursive sync for selected folders.
+
+## Testing and Validation
+
+- Functional coverage: `functional_tests/test_file_sync_onedrive_personal.py`.
+- Related UI smoke coverage: `ui_tests/test_workspace_file_sync_ui.py`.
+- Existing Azure Files and File Sync static coverage was updated to version `0.241.129`.
+
+## Known Limitations
+
+- OneDrive sync uses a global connector identity with application permissions, so tenant administrators must consent to the required Graph permissions.
+- OneDrive is intentionally limited to personal workspaces.
+- Native Google Workspace files are not handled by this connector; Google Workspace should use a separate provider adapter with export handling.
+
+## Version Tracking
+
+- `application/single_app/config.py` was updated to `0.241.129` for the global connector identity update.

+# Personal Workflows
+
+Implemented in version: **0.241.024**
+Enhanced in versions: **0.241.029**, **0.241.033**, **0.241.034**, **0.241.035**, **0.241.036**, **0.241.106**, **0.241.179**, **0.241.193**, **0.241.194**
+
+Implemented in version: **0.241.106** for workflow access governance.
+
+## Overview
+
+Personal Workflows add an optional workspace capability that lets a user save repeatable tasks and run them either manually or on an interval schedule. Each workflow can target either a personal or merged global agent, or run directly against the configured default model or a specific personal/global model endpoint.
+
+Fixed/Implemented in version: **0.241.193** for configurable workflow agent action limits.
+Enhanced in version: **0.241.194** with admin capacity guidance for high action limits.
+
+Related version updates:
+- `application/single_app/config.py` reported version `0.241.106` for workflow access governance.
+- `application/single_app/config.py` reported version `0.241.193` for workflow action limit configuration.
+- `application/single_app/config.py` now reports version `0.241.194` for workflow action limit capacity guidance.
+
+Dependencies:
+- `application/single_app/functions_personal_workflows.py`
+- `application/single_app/functions_workflow_runner.py`
+- `application/single_app/route_backend_workflows.py`
+- `application/single_app/functions_settings.py`
+- `application/single_app/background_tasks.py`
+- `application/single_app/templates/workspace.html`
+- `application/single_app/static/js/workspace/workspace_workflows.js`
+- `deployers/azurecli/appRegistrationRoles.json`
+- `deployers/terraform/main.tf`
+
+## Technical Specifications
+
+Architecture overview:
+- Workflow definitions are stored in the personal workflows Cosmos container.
+- Workflow run history is stored in a dedicated personal workflow runs Cosmos container.
+- The workspace UI exposes a `Personal Workflows` tab and a matching workspace section entry.
+- Scheduled workflows are processed by the background task scheduler through a dedicated polling loop.
+- Each run writes into a dedicated workflow conversation so users can review accumulated prompts and responses later.
+
+Runtime behavior:
+- Trigger types supported in this first phase: `manual` and `interval`.
+- Interval units supported: `seconds`, `minutes`, and `hours`.
+- Runner types supported: `agent` and `model`.
+- Model workflows can use the default app model or an explicit enabled endpoint/model pair.
+- Agent workflows validate that the selected agent is still available for the user at save time.
+- Workflow conversations stay in the same personal conversations container and are split into a dedicated `Workflows` section in the chat sidebar by `chat_type='workflow'`.
+- The standard `Conversations` section excludes workflow chats, while the `Workflows` section shows five items by default and can expand to reveal the rest.
+- The `Workflows` section now mirrors the main sidebar behavior with the same header styling as `Conversations`, no extra divider, and its own scrollable list body.
+- Workflow run history now includes direct links to the dedicated workflow conversation for the overall workflow and for each individual run event.
+- Workflow UI and API access are hidden or blocked unless the effective user policy allows personal workflows.
+- Admins can optionally require the `WorkflowUser` Enterprise App role before a user can open, create, update, delete, run, or inspect personal workflows.
+
+Configuration options:
+- Admins can enable or disable the feature with the `allow_user_workflows` setting in the Admin Settings `Workflow` section.
+- `allow_user_workflows` defaults to `False` so new deployments must explicitly enable personal workflows.
+- `require_member_of_workflow_user` defaults to `False`; when enabled, the signed-in user's role claims must include `WorkflowUser`.
+- `workflow_max_auto_invoke_attempts` defaults to `60` and can be raised in Admin Settings for large workflow runs that need more agent tool or action calls.
+- Values above `100` should be treated as capacity-sensitive. Admins should enable Cosmos DB Throughput automation in SimpleChat so the app can monitor RU pressure and scale up Cosmos when needed, while also watching Azure OpenAI throttling, App Service CPU and memory, and downstream service latency.
+- Scheduled workflows can be paused without deleting the workflow definition.
+- Users can assign a workflow alert priority of `high`, `medium`, `low`, or `none` for global pop-up notifications after each run.
+- Users can create, edit, delete, manually run, and inspect run history from the workspace tab.
+
+File structure:
+- Backend storage and validation: `application/single_app/functions_personal_workflows.py`
+- Workflow execution: `application/single_app/functions_workflow_runner.py`
+- API routes: `application/single_app/route_backend_workflows.py`
+- Scheduler polling: `application/single_app/background_tasks.py`
+- Workspace UI: `application/single_app/templates/workspace.html`
+- Browser behavior: `application/single_app/static/js/workspace/workspace_workflows.js`
+
+## Usage Instructions
+
+How to enable/configure:
+1. Open Admin Settings.
+2. Go to the `Workspaces` tab.
+3. Open the `Workflow` section.
+4. Enable `Enable Personal Workflows`.
+5. Set `Workflow Agent Action Limit` when large workflows need more than the default 60 automatic tool or action calls. For values above 100, enable Cosmos DB Throughput automation in SimpleChat and monitor service capacity.
+6. Optionally enable `Require WorkflowUser App Role` and assign `WorkflowUser` in the Enterprise App.
+
+User workflow:
+1. Open `Personal Workspace`.
+2. Select `Personal Workflows` from the workspace section menu or the tab strip.
+3. Choose `New Personal Workflow`.
+4. Enter a name, optional description, and task prompt.
+5. Pick either an agent runner or a model runner.
+6. Choose a workflow alert priority when you want the run to generate a global pop-up alert modal.
+7. Choose `Manual` or `Interval Schedule` and configure the interval when needed.
+8. Save the workflow and use `Run` to trigger it immediately or let the scheduler pick it up.
+
+Integration points:
+- Manual runs call `POST /api/user/workflows/<workflow_id>/run`.
+- Run history is read from `GET /api/user/workflows/<workflow_id>/runs`.
+- Scheduler execution uses the same runner path as manual execution.
+
+## Testing And Validation
+
+Functional coverage:
+- `functional_tests/test_personal_workflows_feature.py` verifies backend wiring, scheduler integration, workspace UI references, and admin toggle presence.
+- `functional_tests/test_workflow_access_controls.py` verifies workflow defaults, role helpers, route decorators, UI gating snippets, app role deployment definitions, and documentation.
+- `functional_tests/test_workflow_auto_invoke_attempt_settings.py` verifies workflow action limit defaults, admin save wiring, Semantic Kernel loader wiring, and workflow runner scoping.
+
+UI coverage:
+- `ui_tests/test_workspace_workflows_tab.py` validates desktop and mobile rendering, workflow history modal behavior, and new workflow submission from the workspace modal.
+- `ui_tests/test_workflow_priority_alert_modal.py` validates the global workflow alert modal and mark-read flow.
+- `ui_tests/test_admin_workflow_settings_access.py` validates the Admin Settings workflow action limit control.
+
+Performance and limitations:
+- Group workflow support is available separately through the `Group Workflows` feature.
+- Scheduling currently supports interval execution only; calendar-style recurrence is not included.
+- Personal workflow configuration and execution remain user-scoped even when group workflows are enabled.
+- Users must sign out and back in after app role assignment changes so the `WorkflowUser` claim appears in their session.

+# SimpleChat Operation Notifications
+
+Implemented in version: **0.241.030**
+
+## Overview and Purpose
+
+SimpleChat workspace actions now create inbox notifications when they create a group, add a user to a group, or create a conversation. This complements the workflow priority modal by leaving a durable notification trail in the notifications experience.
+
+Related config update:
+- `application/single_app/config.py` now reports version `0.241.030`.
+
+Dependencies:
+- `application/single_app/functions_simplechat_operations.py`
+- `application/single_app/functions_notifications.py`
+- `application/single_app/semantic_kernel_plugins/simplechat_plugin.py`
+- `application/single_app/templates/notifications.html`
+
+## Technical Specifications
+
+Coverage:
+- Group creation creates a personal notification for the creator.
+- Direct group member additions create a notification for the added user and a separate confirmation notification for the acting owner or admin.
+- Group conversation creation fans out personal notifications to the current group membership with deep links into the new conversation.
+- Personal conversation creation through the SimpleChat plugin creates a notification for the acting user, while the standard manual new-chat route stays quiet to avoid noise.
+- Personal collaborative conversation creation notifies the creator and each invited participant.
+
+Notification types:
+- `group_created`
+- `group_member_added`
+- `conversation_created`
+
+Navigation behavior:
+- Group notifications link to `/manage_group/<group_id>` or `/chats?conversationId=<id>` with group context metadata.
+- Conversation notifications use deep links that the chat page already understands.
+
+## Usage Instructions
+
+Examples that now create notifications:
+1. A workflow uses the SimpleChat action to create a new group.
+2. A workflow or user action adds a member to that group.
+3. A workflow or user action creates a new group or collaborative conversation.
+
+Users can review these events from the Notifications page and navigate directly from the notification entry.
+
+## Testing and Validation
+
+Functional coverage:
+- `functional_tests/test_simplechat_operation_notifications.py`
+
+Validation focus:
+- creator notifications for group creation
+- actor and recipient notifications for member additions
+- conversation creation notifications for workflow-driven SimpleChat actions

+# Tableau Action
+
+Implemented in version: **0.241.210**
+
+Related config.py version update: `application/single_app/config.py` is **0.241.210** for this implementation.
+
+## Overview
+
+The Tableau action lets users connect SimpleChat agents to Tableau Server or Tableau Cloud through a first-class, read-only action. It uses Tableau's supported Python REST client, `tableauserverclient`, and exposes content discovery tools for projects, workbooks, views, datasources, and workbook details.
+
+The action has its own configuration workflow in the Add/Edit Action modal. It does not reuse OpenAPI, Databricks, or generic action forms.
+
+Fixed/Implemented in version: **0.241.210**
+
+## Dependencies
+
+- Python package: `tableauserverclient==0.40`
+- Tableau Server or Tableau Cloud HTTPS base URL
+- Tableau personal access token, username/password credentials, or a reusable workspace identity
+- Existing SimpleChat action storage, Key Vault secret handling, and Semantic Kernel plugin loading
+
+## Technical Specifications
+
+- Plugin type: `tableau`
+- Runtime plugin: `semantic_kernel_plugins.tableau_plugin.TableauPlugin`
+- Factory: `semantic_kernel_plugins.tableau_plugin_factory.TableauPluginFactory`
+- Shared defaults and normalization: `functions_tableau_operations.py`
+- Additional settings schema: `application/single_app/static/json/schemas/tableau_plugin.additional_settings.schema.json`
+- Allowed auth definition: `application/single_app/static/json/schemas/tableau.definition.json`
+
+Supported Semantic Kernel functions are read-only:
+
+- `search_tableau_content`
+- `list_projects`
+- `list_workbooks`
+- `list_views`
+- `list_datasources`
+- `get_workbook_details`
+
+The initial implementation intentionally excludes publish, update, delete, refresh, and administrative operations.
+
+## Configuration Options
+
+- `server_url`: Tableau Server or Tableau Cloud base URL.
+- `site_content_url`: optional Tableau site content URL; blank uses the default Tableau Server site.
+- `auth_method`: `personal_access_token` or `username_password`.
+- `pat_name`: Tableau PAT name for PAT authentication.
+- `page_size`: REST API page size, bounded from 1 to 1000.
+- `max_results`: per-call item limit, bounded from 1 to 1000.
+- `timeout`: HTTP timeout in seconds, bounded from 1 to 300.
+- `use_server_version`: enables Tableau Server Client version negotiation.
+
+## Usage Instructions
+
+Create a new action from a personal, group, or admin action surface and choose **Tableau**. Enter the Tableau Server URL and optional site content URL. Choose either personal access token or username/password authentication.
+
+For PAT authentication, provide both the PAT name and PAT secret. For reusable identities, select an action-capable identity from the Tableau identity selector. API key reusable identities provide the PAT secret, while the Tableau form still requires the PAT name. Username/password reusable identities provide the Tableau username and password.
+
+After saving the action, assign it to agents that need Tableau content discovery. Agents can list and search Tableau content that the configured Tableau credentials can access.
+
+## Testing and Validation
+
+- Functional coverage: `functional_tests/test_tableau_action_plugin.py`
+- UI coverage: `ui_tests/test_tableau_action_modal_workflow.py`
+- JavaScript syntax checks: `plugin_modal_stepper.js` and `workspace/view-utils.js`
+- Python compile checks cover the Tableau helper, plugin, factory, loader, route, and identity updates.
+
+## Known Limitations
+
+- The action is read-only in version 0.241.210.
+- Tableau permissions are enforced by Tableau for the configured credentials.
+- Live connectivity is validated only when credentials and a reachable Tableau site are configured in the running app.

+# Tabular Background Generated Exports
+
+Implemented in version: **0.241.046**
+
+Updated through version: **0.241.064**
+
+## Overview
+
+Large tabular generated outputs can now continue outside the chat request when the export is too large to complete safely inline. This keeps chat and workflow requests responsive while a background worker processes structured JSON or CSV output in checkpointed batches.
+
+## Purpose
+
+The feature supports large spreadsheet-driven analysis, including workbooks that reference many supporting documents, by queueing durable generated-output runs when row and batch counts exceed inline thresholds.
+
+## Dependencies
+
+- Azure Cosmos DB container: `tabular_export_runs`, partitioned by `/user_id`
+- Azure Blob Storage personal chat artifacts container
+- Azure OpenAI or APIM-backed GPT chat completion settings
+- Background task scheduler in `background_tasks.py`
+
+## Technical Specifications
+
+### Architecture
+
+- Chat and workflow tabular generated-output requests continue to use the existing inline path for smaller exports.
+- Oversized structured exports are queued with `queue_tabular_generated_output_run(...)`.
+- Input row batches are staged as a single blob-backed JSON payload.
+- Each completed model batch is checkpointed as an output blob.
+- Cosmos stores compact run metadata, progress counts, retry state, and final artifact metadata.
+- The background scheduler claims queued runs with optimistic status updates and resumes from checkpointed output batches.
+- Users can manually continue resumable failed or stale runs from the existing checkpoints without restarting completed batches.
+- Queued retry runs whose retry time has already passed are surfaced as resumable so deployments without active scheduler loops still give users a recovery action.
+- Run status includes safe user-facing status detail, checkpoint summaries, retry timing, heartbeat state, and continuation availability.
+
+### API Endpoints
+
+- `GET /api/tabular/generated-output/runs/<run_id>` returns the current user's public-safe run status.
+- `POST /api/tabular/generated-output/runs/<run_id>/resume` requeues a resumable run for the current user.
+
+### Configuration Options
+
+- `tabular_generated_output_inline_max_rows`
+- `tabular_generated_output_inline_max_batches`
+- `tabular_generated_output_max_batch_rows`
+- `tabular_generated_output_max_batch_chars`
+- `tabular_generated_output_batch_concurrency`
+
+If settings are absent, conservative defaults are used.
+
+### File Structure
+
+- `application/single_app/functions_tabular_generated_exports.py`
+- `application/single_app/route_backend_chats.py`
+- `application/single_app/background_tasks.py`
+- `application/single_app/functions_simplechat_operations.py`
+- `application/single_app/static/js/chat/chat-messages.js`
+
+## Usage Instructions
+
+Users continue requesting tabular structured output in chat or workflows. For smaller exports, the file is attached during the response. For larger exports, the assistant message shows a background progress card and the final download appears when processing completes. If a resumable run stops after a transient infrastructure failure, the card shows a Continue action that queues the same run to resume from completed checkpoints.
+
+When a workflow/document analysis request also creates a full generated tabular export, the generated export is presented as the primary deliverable. The analysis layer may still attach a supporting CSV preview, but redundant analysis JSON and Markdown artifacts are suppressed so they do not compete with the full generated export card.
+
+The progress card displays current status, completed checkpoint counts, processed row counts, estimated remaining time, scheduled retry time, retry-due state, transient retry count, manual continuation count, last update time, and heartbeat time when available.
+
+## Testing and Validation
+
+- Functional regression: `functional_tests/test_tabular_background_generated_exports.py`
+- Functional regression for workflow/document-action presentation: `functional_tests/test_document_analysis_lossless_artifacts.py`
+- UI regression: `ui_tests/test_chat_background_generated_export_status.py`
+- Compile validation covers the modified Python modules.
+
+## Performance Considerations
+
+- The request only stages durable input and queues work for oversized exports.
+- Phase 3 batch packing compacts generated-export prompt payloads, removes internal tabular helper fields from staged model input, avoids duplicating row-linked document excerpts as synthetic attachment text, and packs rows by configurable row and character budgets.
+- Phase 4 bounded concurrency lets the background worker generate a small configurable window of model batches in parallel while checkpointing successful batches and advancing public progress only in contiguous batch order.
+- Background processing writes each completed batch before moving on, allowing the run to resume after worker restarts.
+- The run status API returns compact metadata only, not source rows or generated batch content.
+- User-facing status details are derived from run metadata instead of displaying raw backend errors in the progress card.
+
+## Known Limitations
+
+- Background runs still depend on configured background scheduler capacity and available Azure OpenAI throughput.
+- Completion appears through status polling or on the next chat reload; no push notification is added in this version.
+- Manual continuation applies to retryable failures, stale running leases, queued retries whose retry time has passed, and stale queued runs; hard validation failures remain terminal.
+
+## Related Version Updates
+
+- `application/single_app/config.py` was updated to version **0.241.057** for queued retry recovery and scheduler scan diagnostics.
+- `application/single_app/config.py` was updated to version **0.241.059** for Phase 3 compact batch packing.
+- `application/single_app/config.py` was updated to version **0.241.060** for Phase 4 bounded batch concurrency.
+- `application/single_app/config.py` was updated to version **0.241.064** for generated export artifact presentation cleanup.

+# User Settings Cache Optimization
+
+Implemented in version: **0.242.044**
+
+## Overview
+
+User settings cache optimization reduces repeated Cosmos DB reads for user-specific UI preferences while keeping security-sensitive user settings fresh. The implementation supports both single App Service deployments without Redis and scaled-out App Service deployments with Redis.
+
+## Purpose
+
+SimpleChat reads user settings during shared page rendering and from frontend scripts that initialize theme, navigation, profile image, and tutorial controls. Without caching, a single page load can read the same user settings document multiple times.
+
+This feature adds request-scoped memoization for full user settings and a lightweight UI settings cache for non-security browser chrome preferences.
+
+## Dependencies
+
+- Flask request context for request-scoped memoization
+- Existing app cache configuration in `application/single_app/app_settings_cache.py`
+- Optional Redis cache when `enable_redis_cache` is enabled
+- Cosmos DB user settings container as the source of truth
+
+## Technical Specifications
+
+### Cache Layers
+
+1. Request-scoped cache for full user settings documents.
+2. Lightweight UI settings cache for shared page chrome fields.
+3. Redis-backed UI settings cache when Redis is enabled.
+4. Process-local TTL UI settings cache when Redis is disabled.
+
+### Cached UI Fields
+
+The lightweight UI cache includes fields such as:
+
+- `profileImage`
+- `navLayout`
+- `darkModeEnabled`
+- `showTutorialButtons`
+- `chatLayout`
+- `streamingEnabled`
+- `notifications_per_page`
+
+Security-sensitive fields such as access restrictions and file upload controls are not introduced into the lightweight UI cache contract.
+
+### No-Redis Behavior
+
+In a single App Service deployment without Redis, the UI settings cache is process-local with a short TTL. It does not use per-user Cosmos version documents, avoiding high-cardinality invalidation reads across multiple workers.
+
+### Redis Behavior
+
+In scaled-out deployments with Redis, the UI settings cache uses Redis keys shared by all workers and instances. User settings writes invalidate the lightweight UI cache so later page renders reload current values from Cosmos.
+
+## Primary Files
+
+- `application/single_app/app_settings_cache.py`
+- `application/single_app/functions_settings.py`
+- `application/single_app/app.py`
+- `application/single_app/templates/base.html`
+- `application/single_app/static/js/dark-mode.js`
+- `application/single_app/static/js/sidebar.js`
+- `functional_tests/test_user_settings_cache_optimization.py`
+
+## Usage Instructions
+
+No administrator action is required. The cache behavior follows the existing app Redis configuration:
+
+- Redis disabled: request cache plus process-local UI settings TTL cache.
+- Redis enabled: request cache plus Redis-backed UI settings cache.
+
+## Testing and Validation
+
+Functional coverage is provided by `functional_tests/test_user_settings_cache_optimization.py`.
+
+The test validates:
+
+- Full user settings request memoization markers.
+- Redis and no-Redis UI settings cache contracts.
+- Cache invalidation markers on user settings write paths.
+- Frontend reuse of injected user UI settings before full API fallback.
+
+## Known Limitations
+
+The no-Redis process-local UI cache is intentionally short-lived and per worker. It is designed for low-risk UI preferences, not immediate cross-worker propagation of security decisions.
+
+## Related Version Updates
+
+Implemented in version: **0.242.044**
+
+The application version was updated in `application/single_app/config.py` to track this feature.

+# Visio Ingestion
+
+Implemented in version: **0.241.074**
+
+Improved in versions: **0.241.078**, **0.241.079**
+
+## Overview
+
+Visio ingestion adds native `.vsdx` upload support so users can ask questions about the structured contents of Visio diagrams instead of only treating them as opaque files or converted PDFs.
+
+The feature parses Visio Open Packaging Convention XML, indexes each Visio page as one searchable chunk, stores the original `.vsdx` for enhanced citations, and renders a built-in structural PNG preview for the cited page.
+
+## Dependencies
+
+- Python `zipfile` and `xml.etree.ElementTree` for reading VSDX package parts.
+- Pillow for structural PNG preview rendering.
+- Existing enhanced-citation blob storage for original file retrieval.
+- Existing Azure AI Search chunk indexing pipeline.
+
+## Technical Specifications
+
+### Architecture
+
+The VSDX parser reads `visio/pages/pages.xml` and its relationship file to discover page tabs and page XML parts. Each page XML is parsed for shapes, text, shape data, page dimensions, and connector records. Preview rendering can also expand referenced Visio master stencil shapes so common Azure and service icons have more of their original vector structure without adding an office-suite runtime.
+
+Each page is converted to Markdown-like structured text and saved as one search chunk. The chunk page number matches the Visio page index, so enhanced citation clicks can request the matching visual preview.
+
+### API Endpoint
+
+- `GET /api/enhanced_citations/visio?doc_id={id}&page={page}` returns an `image/png` preview for a Visio page.
+- `GET /api/enhanced_citations/visio?doc_id={id}&download=true` downloads the original `.vsdx` file.
+
+Both routes use the existing enhanced-citation authorization path and require `enable_enhanced_citations`.
+
+### File Structure
+
+- `application/single_app/functions_visio.py` parses VSDX files and renders page previews.
+- `application/single_app/config.py` declares the shared `VISIO_EXTENSIONS` allow-list used by upload validation and enhanced citations.
+- `application/single_app/functions_documents.py` dispatches `.vsdx` uploads to the Visio ingestion flow.
+- `application/single_app/route_enhanced_citations.py` serves Visio previews and downloads.
+- `application/single_app/static/js/chat/chat-enhanced-citations.js` opens Visio citation previews in a Bootstrap modal.
+- `functional_tests/test_visio_ingestion_preview.py` validates parser and renderer behavior.
+
+## Usage Instructions
+
+1. Upload a `.vsdx` file to a supported workspace.
+2. Ask questions about the diagram contents in chat.
+3. Click a Visio citation to open the rendered page preview.
+4. Use the modal download button when the original `.vsdx` is needed.
+
+No separate admin toggle is required beyond existing document upload and enhanced-citation settings.
+
+## Testing and Validation
+
+Test coverage is provided by `functional_tests/test_visio_ingestion_preview.py`, which validates that `artifacts/architecture.vsdx` can be parsed, indexed into page content, rendered as a PNG preview, and expanded with master stencil geometry only for preview rendering. `functional_tests/test_visio_extensions_config.py` validates that the shared Visio extension constant remains exported and included in allowed uploads.
+
+## Performance Considerations
+
+The built-in renderer draws positioned text, connector endpoints, supported VSDX path geometry, selected master stencil vector geometry, curve approximations, dashed containers, and supported embedded media using parsed Visio coordinates. Preview PNGs use bounded supersampling for smoother output. This keeps previews dependency-light and suitable for citation context, but it does not attempt full Visio theme, gradient, shadow, icon, or connector routing fidelity.
+
+For very large diagrams, preview rendering is capped by a configurable maximum edge size.
+
+## Known Limitations
+
+- `.vsd` binary Visio files are not supported.
+- Embedded stencil artwork, curves, gradients, shadows, and theme styling are approximated.
+- Grouped shape coordinate transforms may not perfectly match the Visio desktop rendering.
+- The preview is intended for citation orientation; the original `.vsdx` remains available for exact inspection.

+# Voice-Assisted Workflow and Action Creation
+
+Implemented in version: **0.250.028**
+
+## Overview
+
+Voice-assisted creation extends the existing form speech-to-text controls from agent authoring into workflow and action authoring. Users can type or dictate brief creation details, then use drafting support to turn a workflow task brief into complete workflow or task instructions.
+
+## Dependencies
+
+- Azure Speech Service configuration for speech-to-text form controls.
+- Existing SimpleChat agent instruction drafting model configuration for workflow instruction drafting.
+- Personal workflow, group workflow, personal action, group action, or global action feature access as configured by administrators.
+
+## Technical Specifications
+
+### Architecture
+
+- `application/single_app/static/js/form-voice-input.js` registers voice controls for workflow and action fields.
+- `application/single_app/static/js/workspace/workspace_workflows.js` submits workflow draft requests and inserts returned instructions into the saved `task_prompt` field.
+- `application/single_app/route_backend_workflows.py` exposes `POST /api/workflows/draft-instructions` and applies the same workflow access gates used by workflow management.
+- `application/single_app/templates/workspace.html` and `application/single_app/templates/group_workspaces.html` render the task brief and draft workflow instruction controls.
+- `application/single_app/templates/_plugin_modal.html` exposes the generated action name so users can edit or dictate it.
+
+### API Endpoints
+
+- `POST /api/workflows/draft-instructions`
+  - Request: `workflow_scope`, `name`, `description`, `brief`, `existing_instructions`
+  - Response: `success`, `instructions`
+  - Access: authenticated users only; personal workflow app-role gates and group workflow management role gates are enforced.
+
+### Configuration Options
+
+No new settings are introduced. Voice buttons depend on the existing speech-to-text setting, and workflow drafting depends on existing GPT model settings.
+
+## Usage Instructions
+
+1. Open a personal or group workflow creation modal.
+2. Enter or dictate a workflow name, description, and task brief.
+3. Select **Draft Workflow Instructions** to generate editable workflow or task instructions.
+4. Review and adjust the generated instructions before saving the workflow.
+5. For actions, open the shared action modal and type or dictate display name, name, and description.
+
+## Testing and Validation
+
+- `functional_tests/test_workflow_instruction_drafting.py` validates route, template, JavaScript, voice registry, and payload contract wiring.
+- `ui_tests/test_voice_assisted_form_inputs.py` validates voice controls render on agent, workflow, action, document metadata, and tag fields when speech-to-text is enabled.
+
+## Known Limitations
+
+- Voice controls only render when speech-to-text is enabled and the browser supports local audio recording APIs.
+- Drafted workflow instructions still require user review before save.

+# Workflow Per-Document Analysis And Generated Office Exports
+
+Implemented in version: **0.241.182**
+
+Related version update:
+- `application/single_app/config.py` reports version `0.241.182`.
+
+## Overview
+
+Workflow Analyze actions can now either run across the selected document set as one combined context or run the same prompt against each selected document separately. SimpleChat actions can also create generated Word documents and PowerPoint presentations, allowing workflow prompts to turn each per-document result into a saved workspace artifact.
+
+Dependencies:
+- `application/single_app/functions_document_actions.py`
+- `application/single_app/functions_workflow_runner.py`
+- `application/single_app/functions_simplechat_operations.py`
+- `application/single_app/semantic_kernel_plugins/simplechat_plugin.py`
+- `application/single_app/static/js/workspace/workspace_workflows.js`
+- `application/single_app/templates/workspace.html`
+- `application/single_app/templates/group_workspaces.html`
+
+## Technical Specifications
+
+Architecture overview:
+- Analyze document action configuration includes `analysis_mode` with supported values `combined` and `per_document`.
+- `combined` remains the default and preserves existing workflow behavior.
+- `per_document` makes the runner prepare a one-document workflow for each selected document, reuse the existing Analyze execution path, and combine the replies, coverage, citations, generated artifacts, tabular outputs, token usage, and alert targets.
+- Per-document prompts include runtime guidance telling the model or agent which document is being processed and that generated artifacts should be specific to that document.
+- SimpleChat generated document actions expose `upload_word_document` and `upload_powerpoint_document` alongside the existing Markdown upload action.
+- Group workflow SimpleChat actions default generated uploads to the current group workspace by resolving `workspace_scope="current"` through the plugin manifest `default_group_id`.
+- The existing group upload path still enforces current group access checks before saving artifacts.
+
+Configuration options:
+- Workflow Analyze mode is saved in `document_action.analysis_mode` and mirrored into the legacy `analyze.analysis_mode` payload for compatibility.
+- SimpleChat action capability maps include `upload_word_document` and `upload_powerpoint_document`.
+- Older capability maps inherit the existing `upload_markdown_document` setting for the new Office upload actions when the new keys are absent.
+
+File structure:
+- Backend normalization: `application/single_app/functions_document_actions.py`
+- Workflow execution: `application/single_app/functions_workflow_runner.py`
+- Generated document helpers: `application/single_app/functions_simplechat_operations.py`
+- Semantic Kernel tool wrapper: `application/single_app/semantic_kernel_plugins/simplechat_plugin.py`
+- Workflow modal UI: `application/single_app/templates/workspace.html` and `application/single_app/templates/group_workspaces.html`
+- Workflow modal behavior: `application/single_app/static/js/workspace/workspace_workflows.js`
+
+## Usage Instructions
+
+How to enable/configure:
+1. Enable personal or group workflows from Admin Settings.
+2. Ensure the workflow runner uses an agent or model that has access to the selected documents.
+3. For generated Word or PowerPoint files, enable the matching SimpleChat capability on the action used by the workflow agent.
+
+User workflow:
+1. Open Personal Workspace or Group Workspaces.
+2. Create or edit a workflow.
+3. Set the document action to `Analyze`.
+4. Select the documents to process.
+5. Turn on `Run each document separately` when the same prompt should be applied independently to every selected document.
+6. Use a prompt that asks the workflow agent to call the SimpleChat Word or PowerPoint upload action when saved artifacts are needed.
+
+Integration points:
+- Per-document Analyze uses the same workflow conversation and run history as combined Analyze.
+- Generated Office artifacts are uploaded through the normal document processing pipeline.
+- Group workflow artifacts save into the current group workspace when the workflow is executed from a group context.
+- Workflow activity/history and alert conversation actions open linked conversations in a new browser tab so the current workflow view stays available.
+
+## Testing And Validation
+
+Functional coverage:
+- `functional_tests/test_workflow_per_document_analysis_mode.py` verifies analysis mode normalization, per-document result combination, UI/static contracts, and new-tab link contracts.
+- `functional_tests/test_simplechat_generated_office_exports.py` verifies generated Word and PowerPoint upload helpers, current group scope resolution, capability fallbacks, labels, and frontend capability contracts.
+
+UI coverage:
+- `ui_tests/test_workflow_document_action_modal.py` validates the `Run each document separately` modal control and the saved `analysis_mode='per_document'` payload.
+- `ui_tests/test_workflow_priority_alert_modal.py` validates workflow alert conversation actions opening in a new tab and preserving mark-read behavior.
+
+Performance and limitations:
+- Per-document mode runs one Analyze operation per selected document, so runtime and model/tool usage scale with selected document count.
+- Office byte rendering depends on the installed `python-docx` and `python-pptx` packages; upload helper tests skip the binary rendering assertion when those optional packages are unavailable locally.
+- Per-document mode only changes Analyze behavior when more than one document is selected; a single selected document follows the standard Analyze execution path.

+# Workflow Priority Alerts
+
+Implemented in version: **0.241.029**
+Refined in version: **0.241.032**
+
+## Overview and Purpose
+
+Workflow Priority Alerts extend personal workflows with a user-controlled pop-up alert setting. Each workflow can now raise a `high`, `medium`, or `low` priority modal after a run, or stay silent with `none`.
+
+The alert modal is designed for actionable workflow results, not just passive badge updates. It can deep-link into the workflow conversation, and when an agent run creates or updates another conversation through the built-in SimpleChat action, the alert can surface that destination directly as well.
+
+Related config update:
+- `application/single_app/config.py` now reports version `0.241.032`.
+
+Dependencies:
+- `application/single_app/functions_personal_workflows.py`
+- `application/single_app/functions_workflow_runner.py`
+- `application/single_app/functions_notifications.py`
+- `application/single_app/route_backend_notifications.py`
+- `application/single_app/templates/workspace.html`
+- `application/single_app/templates/base.html`
+- `application/single_app/static/js/workspace/workspace_workflows.js`
+- `application/single_app/static/js/notifications.js`
+
+## Technical Specifications
+
+Architecture overview:
+- Workflow definitions now store `alert_priority` alongside the existing runner and trigger settings.
+- Workflow execution creates personal notifications of type `workflow_priority_alert` when alerting is enabled.
+- Priority-specific icon and color treatment is resolved by the notifications backend before the browser renders the alert.
+- The global modal lives in the shared base template so it can appear on authenticated pages, not just inside the notifications center.
+
+Deep-link behavior:
+- Every alert can point back to the workflow conversation.
+- Agent runs capture SimpleChat plugin invocations through the plugin invocation logger scoped to the workflow conversation.
+- When the agent creates a personal conversation, group conversation, or personal collaborative conversation, the alert stores those linked destinations as modal actions.
+- Group conversation targets align the active group before navigation so the target chat opens in the right workspace context.
+- The modal now promotes the event title as the primary heading, keeps workflow identity in a secondary type card when it differs, and uses a redesigned summary panel closer to the security-style alert layout.
+- When both personal and group-created conversations exist, only the single highest-value created target is shown; group multi-user conversations outrank personal conversations.
+- The modal summarizes long alert bodies into a shorter headline, preserves deeper detail in a nested detail card when it adds signal, highlights the created-conversation action in green, and renders the fallback workflow link as a gray `Open workflow` action.
+
+Notification payload:
+- Notification type: `workflow_priority_alert`
+- Priority values: `high`, `medium`, `low`
+- Disabled state: `none`
+- Metadata includes workflow name, run id, trigger source, response preview or error text, and ordered link targets.
+
+## Usage Instructions
+
+How to configure:
+1. Open Personal Workspace.
+2. Create or edit a workflow.
+3. Set `Pop-up Alert Priority` to `No notification`, `Low priority`, `Medium priority`, or `High priority`.
+4. Save the workflow.
+
+What happens after a run:
+1. The run finishes or fails.
+2. If alerting is enabled, the notification system stores a workflow priority alert.
+3. The global notifications script polls unread workflow alerts and opens the modal.
+4. The modal shows the priority, workflow summary, and one or more conversation links.
+5. The user can dismiss the alert, mark it as read, or open a linked conversation immediately.
+
+## Testing and Validation
+
+Functional coverage:
+- `functional_tests/test_workflow_priority_alerts.py`
+
+UI coverage:
+- `ui_tests/test_workspace_workflows_tab.py`
+- `ui_tests/test_workflow_priority_alert_modal.py`
+
+Validation focus:
+- workflow save payload includes alert priority
+- runner creates workflow alert notifications
+- global modal renders unread workflow alerts
+- modal actions can target workflow, personal, group, and collaborative conversations
+
+## Known Limitations
+
+- The modal suppresses repeat display for the same alert within the current browser session, even if the user closes it without marking it read.
+- Only agent actions captured through the existing plugin invocation logger can contribute extra linked conversations beyond the default workflow conversation.
+- Alert delivery remains polling-based, so scheduled workflow alerts are near-real-time rather than push-driven.

+# Workspace Identities
+
+Implemented in version: **0.241.095**
+Initial foundation: **0.241.091**
+Action binding implemented in: **0.241.095**
+Azure Files File Sync identity support implemented in: **0.241.127**
+Global cloud drive File Sync identities implemented in: **0.241.129**
+
+## Overview
+
+Workspace identities are reusable authentication profiles for personal, group, public, and global capabilities. They are intentionally not File Sync-specific: File Sync sources and actions can reference the same identity catalog instead of each feature creating its own credential silo.
+
+Fixed/Implemented in version: **0.241.095**
+
+Version reference: `application/single_app/config.py` was updated to `0.241.095` when action identity binding was implemented.
+
+## Dependencies
+
+- Workspace identity APIs require an authenticated user.
+- Group identities require an active group role of Owner, Admin, or DocumentManager.
+- Public workspace identities require Owner, Admin, or DocumentManager access to the target public workspace and are limited to File Sync usage.
+- Global identities are admin-managed and can be used by global actions and approved File Sync cloud drive connectors.
+- Secrets use the existing Key Vault dynamic secret system when Key Vault storage is enabled.
+
+## Technical Specifications
+
+Identity records are stored in scope-specific Cosmos DB containers:
+
+- `personal_workspace_identities`, partitioned by `/user_id`
+- `group_workspace_identities`, partitioned by `/group_id`
+- `public_workspace_identities`, partitioned by `/public_workspace_id`
+- `global_workspace_identities`, partitioned by `/global_id`
+
+The route layer exposes generic identity APIs:
+
+- `/api/workspace-identities/personal/identities`
+- `/api/workspace-identities/group/identities`
+- `/api/workspace-identities/public/<public_workspace_id>/identities`
+- `/api/admin/workspace-identities/global/identities`
+- `/api/admin/workspace-identities/<scope_type>/<scope_id>/identities`
+
+Each identity carries usage metadata behind the scenes, but the UI presents it as simple **Used For** checkboxes. Personal and group identities can be used for File Sync and Actions. Public workspace identities are constrained to File Sync. Global identities can be used for Actions and admin-approved cloud drive File Sync connectors.
+
+Supported identity auth types in the catalog include username/password, anonymous, API key, bearer token, client secret, connection string, and managed identity. File Sync consumes SMB-compatible username/password and anonymous identities for SMB sources, managed identity, client secret, or connection string identities for Azure Files sources, and global client-secret identities for OneDrive cloud-drive sync. Actions consume API key, bearer token, client secret, connection string, managed identity, and username/password identities. Username/password identities show the domain as optional with helper text because not every account requires a domain. Managed identity selection can carry an optional managed identity client ID through the API for service integrations that need a user-assigned identity.
+
+## Usage Instructions
+
+Users manage identities from the **Identities** tab in personal, group, and public workspace pages. SimpleChat admins manage global identities from the **Global Identities** tab in Admin Settings. Add, view, and edit flows open in a Bootstrap modal with grouped cards for identity details, used-for checkbox selection, and authentication. File Sync source setup uses the **Identity and Authentication** card to choose a reusable workspace identity or source-local credentials for workspace-owned connectors. OneDrive uses an admin-managed global File Sync identity and does not ask personal users to manage tenant app credentials.
+
+Action setup now uses the same identity catalog. Personal actions can use personal identities, group actions can use identities from the active group, and global actions can use global identities. Public workspace identities are not exposed to actions. Action manifests store only `identity_id` and `auth.type = "identity"`; runtime code resolves secrets through `functions_workspace_identities.py` so credentials are not copied into action records.
+
+## Testing and Validation
+
+- `functional_tests/test_file_sync_capability.py` validates workspace identity containers, global identity routes, File Sync identity consumption, credential redaction, and UI wiring.

+# Core Document Search And Summarization
+
+Version implemented: **0.241.007**
+
+## Overview and Purpose
+
+This feature adds a shared backend document-search service, a dedicated authenticated search API, and an always-loaded Semantic Kernel core plugin for search and summarization.
+
+The goal is to give agents and backend callers a common way to:
+
+- Run relevance-ranked hybrid search with a bounded, caller-overridable top-N.
+- Retrieve ordered chunks for a specific document instead of relying only on distilled search hits.
+- Generate hierarchical summaries across the full document by summarizing chunk windows and then reducing the intermediate summaries.
+
+Dependencies:
+
+- Azure AI Search chunk indexes for personal, group, and public workspaces
+- Azure OpenAI chat model configuration for summary generation
+- Semantic Kernel core plugin loading in the shared kernel loader
+
+## Technical Specifications
+
+### Architecture Overview
+
+The feature is split into three thin layers over one shared service:
+
+1. `functions_search.py` keeps hybrid search and now exposes shared top-N and scope normalization helpers.
+2. `functions_search_service.py` resolves document scope, retrieves ordered chunks, builds chunk windows, and performs hierarchical summarization.
+3. Adapters expose the shared service through:
+   - `route_backend_search.py` for authenticated backend APIs
+   - `semantic_kernel_plugins/document_search_plugin.py` for always-loaded Semantic Kernel access
+
+This keeps the HTTP API and the Semantic Kernel plugin behavior aligned and makes future comparison workflows easier to add.
+
+### API Endpoints
+
+The backend route module adds three authenticated endpoints:
+
+- `POST /api/search/documents`
+  - Runs hybrid search.
+  - Supports `query`, `doc_scope`, `top_n`, `document_id` or `document_ids`, optional tags, and optional scope hints.
+- `POST /api/search/document-chunks`
+  - Resolves an accessible document and returns ordered chunks.
+  - Supports optional windowing by pages or chunks.
+- `POST /api/search/document-summary`
+  - Resolves a document, retrieves its ordered chunks, windows the content, summarizes each window, and reduces the intermediate summaries into a final result.
+  - Supports optional focus instructions and target-length overrides.
+
+### Semantic Kernel Plugin Functions
+
+The core plugin is loaded for model-only and agent-backed kernel sessions and exposes three functions:
+
+- `search_documents`
+- `retrieve_document_chunks`
+- `summarize_document`
+
+The plugin resolves the current signed-in user at invocation time and calls the shared service directly rather than going through HTTP.
+
+### Summary Workflow
+
+The summarization workflow is hierarchical:
+
+1. Resolve an accessible document in personal, group, or public scope.
+2. Retrieve ordered chunks for the document.
+3. Build chunk windows by pages when page numbers are available, otherwise by chunk count.
+4. Summarize each window to a configurable intermediate target.
+5. Reduce intermediate summaries in batches until a single final summary remains or the configured reduction limit is reached.
+
+Default behavior keeps the first-pass window summaries and final summary at two pages unless the caller overrides those values.
+
+### File Structure
+
+- `application/single_app/functions_search.py`
+- `application/single_app/functions_documents.py`
+- `application/single_app/functions_search_service.py`
+- `application/single_app/route_backend_search.py`
+- `application/single_app/semantic_kernel_plugins/document_search_plugin.py`
+- `application/single_app/semantic_kernel_loader.py`
+- `functional_tests/test_document_search_api_and_plugin.py`
+
+## Usage Instructions
+
+### Backend API Usage
+
+Use the backend endpoints when server-side code or future UI features need direct access to search, chunk retrieval, or summarization without invoking an agent.
+
+Typical request patterns:
+
+- Search a workspace with default distilled behavior and an explicit `top_n`.
+- Retrieve all ordered chunks for a document before downstream processing.
+- Summarize a document with focus instructions such as risks, deadlines, implementation details, or policy requirements.
+
+### Agent Usage
+
+Agents can use the core plugin to:
+
+- Search for relevant chunks across accessible documents.
+- Pull the full ordered chunk stream for one document when distilled search is not enough.
+- Generate a hierarchical summary with caller-specified focus and length guidance.
+
+This is intended to improve document-grounded summarization today and to support future document-to-document or version-to-version comparison workflows without changing the core retrieval contract.
+
+## Testing and Validation
+
+### Test Coverage
+
+Functional coverage validates:
+
+- Shared search helper exposure and document-id propagation
+- Shared search service entry points for search, retrieval, and summarization
+- Backend route registration and authentication decorators
+- Core plugin kernel-function contract
+- Loader and Flask app registration
+
+Related test:
+
+- `functional_tests/test_document_search_api_and_plugin.py`
+
+### Known Limitations
+
+- Summaries are generated on demand and are not persisted or cached in this implementation.
+- Very large documents can require multiple summarization stages and multiple model calls.
+- Comparison workflows are not included yet, but the retrieval and scope-resolution shapes are designed to support them.

+# Staging UI CI/CD with GitHub Actions (v0.241.014)
+
+## Overview
+
+SimpleChat now includes a repeatable staging CI/CD pattern for repository administrators who want to validate the full Azure deployment path before promoting changes to `main`.
+
+Implemented in version: **0.241.014**
+
+Updated in version: **0.241.016** for the App Service warm-up wait behavior.
+Updated in version: **0.241.017** for Microsoft Playwright Workspaces provisioning and Azure-hosted browser execution.
+Updated in version: **0.241.018** for CI bearer session authentication with the GitHub Actions OIDC service principal.
+
+This feature adds:
+
+- A GitHub Actions workflow that runs on the `Staging` branch.
+- Azure OIDC authentication for `azd up` or `azd deploy` without storing an Azure client secret in GitHub.
+- A reusable PowerShell bootstrap script for creating the CI app registration, federated credential, Azure role assignments, and GitHub Environment values.
+- An authenticated Playwright smoke test that starts a chat conversation, waits for an assistant response, and cleans up the created conversation.
+- A Microsoft Playwright Workspaces resource for running the staging smoke path on Azure-hosted browsers.
+- A disabled-by-default `/ci-auth/session` endpoint that lets staging CI exchange a freshly minted app-only bearer token for a Flask browser session.
+
+The related version update is tracked in `application/single_app/config.py`.
+
+## Dependencies
+
+- Azure CLI authenticated as an administrator for bootstrap setup.
+- Azure Developer CLI (`azd`).
+- GitHub CLI (`gh`) authenticated with permission to manage repository environments, variables, and secrets.
+- A protected GitHub Environment named `Staging`.
+- A staging `azd` environment, normally named `staging`.
+- A SimpleChat Enterprise App registration with the `Admin` app role assignable to the GitHub Actions service principal, or a Playwright storage state file for a dedicated staging test user/admin.
+
+## Architecture
+
+The account model uses the same GitHub OIDC service principal for deployment and staging UI automation, but keeps the browser login path tightly scoped:
+
+- The GitHub workflow uses an Entra app registration and service principal with a GitHub OIDC federated credential. This identity deploys Azure resources and runs `azd`.
+- For CI bearer auth, the workflow mints a short-lived token for the SimpleChat Enterprise App resource (`api://<client-id>`), calls `/ci-auth/session`, and receives a normal Flask session cookie for the test run.
+- Browser storage state remains supported as a fallback for workflows that must test a real user session.
+
+The workflow file is located at:
+
+```text
+.github/workflows/staging-azd-ui-tests.yml
+```
+
+The bootstrap script is located at:
+
+```text
+deployers/Initialize-GitHubActionsStaging.ps1
+```
+
+The staging smoke test is located at:
+
+```text
+ui_tests/test_staging_chat_smoke.py
+```
+
+## GitHub Environment Values
+
+The bootstrap script writes these GitHub Environment variables:
+
+```text
+AZURE_CLIENT_ID
+AZURE_TENANT_ID
+AZURE_SUBSCRIPTION_ID
+AZURE_LOCATION
+AZURE_ENV_NAME
+DEPLOYMENT_APPNAME
+SIMPLECHAT_UI_BASE_URL
+SIMPLECHAT_UI_AUTH_RESOURCE
+PLAYWRIGHT_SERVICE_URL
+PLAYWRIGHT_WORKSPACE_NAME
+PLAYWRIGHT_WORKSPACE_RESOURCE_ID
+```
+
+The bootstrap script writes these GitHub Environment secrets when values are available:
+
+```text
+AZD_ENV_FILE_B64
+SIMPLECHAT_UI_STORAGE_STATE_B64
+SIMPLECHAT_UI_ADMIN_STORAGE_STATE_B64
+```
+
+`AZD_ENV_FILE_B64` contains the base64-encoded `azd env get-values` output for the target environment. This keeps the workflow reusable without requiring every `azd env set` value to be represented as a separate GitHub secret.
+
+## Bootstrap Usage
+
+From the repository root or the `deployers` folder, sign in first:
+
+```powershell
+az login
+azd auth login
+gh auth login
+```
+
+Create or refresh the staging CI/CD identity and GitHub Environment values:
+
+```powershell
+cd deployers
+.\Initialize-GitHubActionsStaging.ps1 `
+    -GitHubRepository "microsoft/simplechat" `
+    -GitHubEnvironment "Staging" `
+    -AzdEnvironmentName "staging" `
+    -AppName "simplechat" `
+    -AzureLocation "eastus" `
+    -UiStorageStatePath "..\ui_tests\artifacts\auth\storage_state.json"
+```
+
+For an admin-only smoke test session, use `-AdminUiStorageStatePath` instead of `-UiStorageStatePath`.
+
+By default, the bootstrap script also configures CI bearer auth for staging when it can resolve `ENTERPRISE_APP_CLIENT_ID` from the azd environment. It allows the SimpleChat `Admin` app role to be assigned to applications, assigns that role to the GitHub Actions service principal, sets `ENABLE_CI_BEARER_SESSION_AUTH=true` and `CI_BEARER_SESSION_ALLOWED_APP_IDS=<github-actions-client-id>` on the staging App Service, and writes `SIMPLECHAT_UI_AUTH_RESOURCE=api://<simplechat-enterprise-app-client-id>` to the GitHub Environment.
+
+Use `-SkipCiBearerSessionAuth` if you want the workflow to require browser storage state instead.
+
+To assign a dedicated test user or group to the SimpleChat Enterprise App during bootstrap, provide the Enterprise App client ID and principal object ID:
+
+```powershell
+.\Initialize-GitHubActionsStaging.ps1 `
+    -GitHubRepository "microsoft/simplechat" `
+    -EnterpriseAppClientId "<simplechat-enterprise-app-client-id>" `
+    -UiTestPrincipalObjectId "<user-or-group-object-id>" `
+    -UiTestAppRoleValue "User"
+```
+
+The script performs that assignment with your current Azure/Graph permissions during bootstrap. The GitHub Actions deployment identity does not need ongoing Graph write permissions for normal staging deployments.
+
+## UI Authentication Options
+
+The preferred staging CI path is CI bearer auth. The workflow acquires a fresh app-only token during each run with:
+
+```bash
+az account get-access-token --resource "$SIMPLECHAT_UI_AUTH_RESOURCE"
+```
+
+That token is masked in the job logs, exported only for the current job, and used by both the Azure Playwright Workspaces smoke test and the Python smoke test to establish a browser session through `/ci-auth/session`.
+
+### Capturing Playwright Storage State
+
+A staging browser session can be captured locally with Playwright:
+
+```powershell
+cd ui_tests
+..\.venv\Scripts\python.exe -m playwright codegen "$env:SIMPLECHAT_UI_BASE_URL/chats" --save-storage artifacts\auth\storage_state.json
+```
+
+Sign in as the dedicated staging test user, then close the browser. Rerun the bootstrap script with `-UiStorageStatePath` to update the GitHub Environment secret. This is only needed when you want to test a real user session instead of the OIDC-backed CI service principal session.
+
+GitHub secrets have a size limit. If the base64-encoded storage state becomes too large, store the state in Azure Key Vault and extend the workflow to retrieve it with the OIDC identity.
+
+## Workflow Behavior
+
+On a push to `Staging`, the workflow:
+
+1. Authenticates to Azure using GitHub OIDC.
+2. Restores the `azd` environment from `AZD_ENV_FILE_B64`.
+3. Runs `azd up --no-prompt` by default.
+4. Resolves or uses `SIMPLECHAT_UI_BASE_URL`.
+5. Acquires a short-lived SimpleChat UI access token when `SIMPLECHAT_UI_AUTH_RESOURCE` is configured.
+6. Waits up to 15 minutes for App Service warm-up. It checks `/external/healthcheckz`, `/external/healthcheck`, and the authenticated `/chats` route so normal post-deploy 503 responses during cold start do not fail the job too early.
+7. Installs Playwright dependencies.
+8. Restores the authenticated browser storage state when storage-state secrets are present.
+9. Runs `npm run test:staging:azure` from `ui_tests/playwright-workspaces` against Microsoft Playwright Workspaces.
+10. Runs `python -m pytest ui_tests/test_staging_chat_smoke.py -m ui -ra` as the existing Python smoke validation path.
+11. Uploads UI test artifacts, screenshots, and traces if present.
+
+Manual dispatch can choose `azd deploy` for code-only validation:
+
+```text
+azd_command: deploy
+```
+
+## Azure Permissions
+
+Because `deployers/bicep/main.bicep` is subscription-scoped and creates role assignments, a full `azd up` workflow generally requires the CI service principal to have:
+
+- `Contributor`
+- `User Access Administrator`
+
+The bootstrap script assigns these at subscription scope by default so `azd up` can fully validate staging infrastructure before `main`.
+
+The same script also creates or updates a Microsoft Playwright Workspaces resource named `<AppName>-<AzdEnvironmentName>-pw` in the staging resource group, assigns the GitHub Actions service principal `Playwright Workspace Contributor` at that workspace scope, and writes `PLAYWRIGHT_SERVICE_URL` to the GitHub Environment. Playwright Workspaces are not available in every Azure region, so the script defaults the workspace region to `eastus` while keeping the resource in the staging resource group.
+
+For UI authentication, the service principal is assigned the SimpleChat Enterprise App `Admin` app role. The app only accepts that token through `/ci-auth/session` when `ENABLE_CI_BEARER_SESSION_AUTH=true` and the caller app ID is explicitly listed in `CI_BEARER_SESSION_ALLOWED_APP_IDS`.
+
+For a narrower deploy-only pattern against existing staging infrastructure, pass a resource group scope with `-RoleAssignmentScope` and run the workflow with `azd_command: deploy`.
+
+## Testing and Validation
+
+Coverage added in this version:
+
+- `functional_tests/test_staging_ui_cicd_workflow.py` validates that the workflow, bootstrap script, and smoke test are present and connected to OIDC, `azd`, GitHub Environment secrets, and Playwright.
+- `ui_tests/test_staging_chat_smoke.py` validates a real browser chat loop against the deployed staging environment.
+- `ui_tests/playwright-workspaces/staging-chat-smoke.spec.js` validates the same path through Microsoft Playwright Workspaces.
+
+Known limitations:
+
+- `gh` is required to write GitHub Environment secrets automatically. Without it, the script can still create Azure OIDC assets when run with `-SkipGitHubConfiguration`.
+- Storage state expires and must be refreshed periodically when storage-state authentication is used.
+- Private-network-only staging environments require a runner and browser execution path with network access to the App Service.

+# Cosmos Query Plugin
+
+Implemented in version: **0.241.022**
+
+## Overview
+
+The Cosmos Query Plugin adds a read-only Azure Cosmos DB for NoSQL action type to the shared action system. It is designed to mirror the existing SQL action workflow where that makes sense, while keeping the first release intentionally narrow and safer.
+
+This version supports one configured Cosmos DB container per action, managed identity authentication only, read-only `SELECT` queries only, and configuration-supplied field hints instead of runtime schema discovery.
+
+Related config update: `application/single_app/config.py` now sets `VERSION = "0.241.022"`.
+
+## Dependencies
+
+- Azure Cosmos DB Python SDK
+- Azure Identity with `DefaultAzureCredential`
+- Shared plugin modal flow in the workspace and group workspace experiences
+- Shared Semantic Kernel plugin loading and validation pipeline
+
+## Technical Specifications
+
+### Architecture
+
+The feature is split across backend validation and execution, loader integration, and shared modal UI support.
+
+- Backend plugin: `application/single_app/semantic_kernel_plugins/cosmos_query_plugin.py`
+- Manifest validation: `application/single_app/semantic_kernel_plugins/plugin_health_checker.py`
+- Loader instruction injection: `application/single_app/semantic_kernel_loader.py`
+- Connection test route: `application/single_app/route_backend_plugins.py`
+- Shared modal UI: `application/single_app/templates/_plugin_modal.html`
+- Shared modal controller: `application/single_app/static/js/plugin_modal_stepper.js`
+- Shared type icon mapping: `application/single_app/static/js/workspace/view-utils.js`
+
+### Action Type Shape
+
+The new action type is `cosmos_query`.
+
+Required configuration:
+
+- `endpoint`
+- `additionalFields.database_name`
+- `additionalFields.container_name`
+- `additionalFields.partition_key_path`
+- `auth.type = identity`
+- `auth.identity = managed_identity`
+
+Optional configuration:
+
+- `additionalFields.field_hints`
+- `additionalFields.max_items`
+- `additionalFields.timeout`
+
+### Runtime Behavior
+
+- Queries must be read-only `SELECT` statements.
+- Mutation and administrative keywords are blocked before execution.
+- Query parameters are normalized into Cosmos SDK `@name` placeholders.
+- When a partition key is provided, the plugin scopes the query to a single logical partition.
+- The plugin captures execution metadata such as request charge and activity ID.
+- The loader injects configured Cosmos container guidance into agent instructions so the model can use the configured field hints.
+
+## Usage Instructions
+
+### How to Configure
+
+1. Open the shared action modal from the workspace or group workspace actions area.
+2. Select the `Cosmos Query` action type.
+3. Provide the account endpoint, database name, container name, and partition key path.
+4. Optionally add one field hint per line to guide query construction.
+5. Optionally tune the max item cap and timeout.
+6. Use the built-in Cosmos connection test before saving.
+
+### Authentication Model
+
+This feature uses managed identity only in v0.241.022.
+
+- Assign the application's managed identity a Cosmos DB built-in data reader role for the target account.
+- No connection strings, keys, or user-password flows are exposed in the modal.
+
+### Integration Points
+
+- The action modal now shows a dedicated Cosmos configuration step.
+- The summary step now renders a Cosmos-specific configuration card.
+- Saved manifests flow through the same plugin validation and loading pipeline as other action types.
+
+## Testing and Validation
+
+Functional coverage:
+
+- `functional_tests/test_cosmos_query_plugin.py`
+
+UI coverage:
+
+- `ui_tests/test_workspace_cosmos_action_modal.py`
+
+Validation focus:
+
+- read-only query enforcement
+- parameter normalization
+- instruction-context generation
+- loader discovery
+- workspace modal rendering, connection test wiring, and summary rendering
+
+## Known Limitations
+
+- One container per action in this version
+- No runtime container schema discovery
+- No mutation support
+- Managed identity only
+- No dedicated group or admin Cosmos UI variations beyond the shared modal behavior

+# SimpleChat Agent Action
+
+Implemented in version: **0.241.022**
+
+## Overview
+
+The SimpleChat Agent Action adds a native action type that can create groups, add users to groups, create group collaborative conversations, create personal conversations, and create personal collaborative conversations.
+
+This action always runs in the invoking user's identity and permission context, even when the action itself is globally defined.
+
+Related config update: `application/single_app/config.py` now sets `VERSION = "0.241.022"`.
+
+## Dependencies
+
+- Existing group workspace APIs and permission helpers
+- Existing personal and collaborative conversation storage paths
+- Microsoft Graph user lookup with the signed-in user's token
+- Shared action modal and agent modal workflows
+- Shared Semantic Kernel plugin loader
+
+## Technical Specifications
+
+### Architecture
+
+- Shared backend operations: `application/single_app/functions_simplechat_operations.py`
+- Built-in SK plugin: `application/single_app/semantic_kernel_plugins/simplechat_plugin.py`
+- Loader overlay for action-level defaults and per-agent capability filtering: `application/single_app/semantic_kernel_loader.py`
+- Plugin validation and registration support: `application/single_app/semantic_kernel_plugins/plugin_health_checker.py`, `application/single_app/semantic_kernel_plugins/logged_plugin_loader.py`
+- Shared action modal capability UI: `application/single_app/templates/_plugin_modal.html`, `application/single_app/static/js/plugin_modal_stepper.js`
+- Shared agent modal capability UI: `application/single_app/templates/_agent_modal.html`, `application/single_app/static/js/agent_modal_stepper.js`
+
+### Runtime Behavior
+
+- Group creation reuses the existing `enable_group_workspaces`, `enable_group_creation`, and `CreateGroups` role checks.
+- Group membership changes reuse the existing direct-add behavior; no new approval workflow was introduced.
+- Group conversation creation falls back to the agent's group context or the user's active group when `group_id` is omitted.
+- Personal collaborative conversation creation resolves invitees through Microsoft Graph using the current user's access token.
+- Action-level capability defaults are stored in `additionalFields.simplechat_capabilities`.
+- Per-agent capability selections are stored in `other_settings.action_capabilities` and override the action defaults when the plugin is loaded.
+
+### Capability Storage
+
+Action defaults are stored on the action itself:
+
+```json
+{
+  "simplechat_capabilities": {
+    "create_group": true,
+    "add_group_member": true,
+    "create_group_conversation": true,
+    "create_personal_conversation": true,
+    "create_personal_collaboration_conversation": true
+  }
+}
+```
+
+Agent-specific overrides are stored per selected action ID under `other_settings.action_capabilities`.
+
+## Usage Instructions
+
+1. Create or edit an action and select the `Simple Chat` action type.
+2. In the action modal, enable only the default SimpleChat capabilities that action should expose.
+3. Attach that action to an agent in the agent modal.
+4. Optionally narrow the capabilities further for that specific agent assignment.
+5. Save the agent. The runtime will expose only the resulting enabled SimpleChat functions to the model.
+
+## Testing and Validation
+
+Functional coverage:
+
+- `functional_tests/test_simplechat_agent_action.py`
+
+UI coverage:
+
+- `ui_tests/test_agent_modal_simplechat_capabilities.py`
+- `ui_tests/test_workspace_simplechat_action_modal.py`
+
+Validation focus:
+
+- plugin discovery
+- action-level capability defaults
+- per-agent runtime capability override behavior
+- action modal rendering and summary behavior
+- agent modal rendering and persistence into additional settings JSON
+
+## Known Limitations
+
+- Group member resolution is only as precise as the signed-in user's Microsoft Graph access and search results.
+- The action intentionally reuses the existing direct-add group member flow instead of introducing a separate invite acceptance workflow.

+# Generated Artifact Markdown View
+
+Fixed/Implemented in version: **0.241.023**
+
+## Overview and Purpose
+
+Generated Markdown artifacts in chat now include a `View MD` action next to `Download MD`. The action opens the generated file in a modal and renders the Markdown so users can inspect the artifact without downloading it first.
+
+## Dependencies
+
+- Chat generated analysis artifact metadata with `artifact_message_id` or `document_id`
+- Existing authorized artifact download endpoints
+- Browser-side `marked` and `DOMPurify` libraries loaded by the chat page
+- Existing citation modal infrastructure in `chat-citations.js`
+
+## Technical Specifications
+
+### Architecture Overview
+
+The generated artifact card detects Markdown artifacts by `output_format` (`md` or `markdown`) or by `.md` / `.markdown` file extension. When a Markdown artifact is detected, the card renders a `View MD` button alongside the existing download action.
+
+Clicking `View MD` fetches the same authorized artifact content used for downloads and passes it to the citation modal with Markdown rendering enabled. The modal sanitizes `marked.parse(...)` output with `DOMPurify.sanitize(...)` before inserting it into the page.
+
+### API Endpoints
+
+- `GET /api/chat_artifacts/download?conversation_id=<id>&message_id=<id>`
+- `GET /api/workspace_documents/download?doc_id=<id>`
+
+### Configuration Options
+
+No new configuration is required.
+
+### File Structure
+
+- `application/single_app/static/js/chat/chat-messages.js` adds the `View MD` action and artifact fetch logic.
+- `application/single_app/static/js/chat/chat-citations.js` reuses the citation modal and adds safe Markdown rendering support.
+- `application/single_app/static/css/chats.css` constrains rendered Markdown modal content.
+- `ui_tests/test_chat_generated_tabular_output_card.py` covers rendered previews and the full Markdown modal view.
+
+## Usage Instructions
+
+When a chat response creates a Markdown artifact, users can choose:
+
+- `Download MD` to save the file locally.
+- `View MD` to render the generated Markdown in a modal.
+- `Add to Workspace` when the artifact can be promoted into a workspace.
+
+## Testing and Validation
+
+The UI test injects a generated Markdown artifact card, verifies the preview renders Markdown, clicks `View MD`, and confirms the modal renders headings and bold text while stripping unsafe event-handler attributes.
+
+## Known Limitations
+
+The modal view is only shown for artifacts detected as Markdown. JSON, CSV, and other generated formats continue to use their existing download and preview behavior.

+# Cosmos Query Plugin
+
+Implemented in version: **0.241.024**
+
+## Overview
+
+This update extends the Cosmos Query Plugin so the shared action system now supports two authentication paths for Azure Cosmos DB for NoSQL:
+
+- Managed identity
+- Account key
+
+The original Cosmos action release stayed intentionally narrow. This follow-up keeps the same one-container, read-only design while adding account-key support for environments that already use Key Vault-backed action secret storage.
+
+Related config update: `application/single_app/config.py` now sets `VERSION = "0.241.024"`.
+
+## Dependencies
+
+- Azure Cosmos DB Python SDK
+- Azure Identity with `DefaultAzureCredential`
+- Existing Key Vault action secret storage helpers in `functions_keyvault.py`
+- Shared plugin modal flow in workspace and group workspace experiences
+- Shared Semantic Kernel plugin loading and validation pipeline
+
+## Technical Specifications
+
+### Architecture
+
+The account-key enhancement touches the existing Cosmos action runtime, validation, connection test route, and shared modal UI.
+
+- Backend plugin: `application/single_app/semantic_kernel_plugins/cosmos_query_plugin.py`
+- Manifest validation: `application/single_app/semantic_kernel_plugins/plugin_health_checker.py`
+- Connection test route: `application/single_app/route_backend_plugins.py`
+- Action type definition: `application/single_app/static/json/schemas/cosmos_query.definition.json`
+- Shared modal UI: `application/single_app/templates/_plugin_modal.html`
+- Shared modal controller: `application/single_app/static/js/plugin_modal_stepper.js`
+
+### Action Type Shape
+
+The action type remains `cosmos_query`.
+
+Required configuration:
+
+- `endpoint`
+- `additionalFields.database_name`
+- `additionalFields.container_name`
+- `additionalFields.partition_key_path`
+- `auth.type = identity | key`
+
+Additional requirements by auth type:
+
+- `identity`: no secret is required; the app uses `DefaultAzureCredential`
+- `key`: `auth.key` is required and can be persisted through the existing Key Vault action-secret helpers
+
+Optional configuration:
+
+- `additionalFields.field_hints`
+- `additionalFields.max_items`
+- `additionalFields.timeout`
+
+### Runtime Behavior
+
+- Queries must still be read-only `SELECT` statements.
+- Mutation and administrative keywords are still blocked before execution.
+- The runtime now chooses the Cosmos SDK credential based on `auth.type`:
+  - `identity` uses `DefaultAzureCredential()`
+  - `key` uses the configured account key string
+- The connection test route now resolves stored Key Vault secret references during edit-time tests, so existing key-backed actions can be re-tested without re-entering the key.
+- The shared modal summary now reflects whether the action uses Managed Identity or Account Key.
+
+## Usage Instructions
+
+### How to Configure
+
+1. Open the shared action modal from the workspace or group workspace actions area.
+2. Select the `Cosmos Query` action type.
+3. Provide the account endpoint, database name, container name, and partition key path.
+4. Choose either `Managed Identity` or `Account Key`.
+5. If using `Account Key`, provide the primary or secondary account key.
+6. Optionally add one field hint per line to guide query construction.
+7. Optionally tune the max item cap and timeout.
+8. Use the built-in Cosmos connection test before saving.
+
+### Authentication Model
+
+Managed identity remains the recommended option.
+
+- Use managed identity when the app identity has Azure Cosmos DB built-in data reader access.
+- Use account keys when RBAC-based access is not the right fit for the target environment.
+- When app-level Key Vault secret storage is enabled, account keys follow the same `auth.key` secret-storage path already used by other action types.
+
+## Testing and Validation
+
+Functional coverage:
+
+- `functional_tests/test_cosmos_query_plugin.py`
+
+UI coverage:
+
+- `ui_tests/test_workspace_cosmos_action_modal.py`
+
+Validation focus:
+
+- read-only query enforcement
+- parameter normalization
+- account-key credential wiring into the Cosmos SDK client
+- workspace modal auth switching
+- browser-side Cosmos connection test payload generation
+- summary rendering for account-key auth
+
+## Known Limitations
+
+- One container per action in this version
+- No runtime container schema discovery
+- No mutation support
+- No connection-string-based Cosmos auth path
+- No dedicated group or admin Cosmos UI variations beyond the shared modal behavior

+# Profile Workspace Tabs (v0.241.028)
+
+## Overview and Purpose
+
+Implemented in version: **0.241.028**
+
+The Profile page now hosts the user's group workspace management and public workspace management as dedicated tabs. This keeps account-level workspace tasks in the same profile area as feedback and safety violations while preserving the legacy URLs as redirects.
+
+## Dependencies
+
+- Flask profile route and existing workspace APIs
+- Bootstrap 5 tabs, modals, tables, and button groups
+- Existing group workspace APIs under `/api/groups`
+- Existing public workspace APIs under `/api/public_workspaces`

+The `/profile` route accepts two new tab values: `groups` and `public-workspaces`. The route calculates small permission booleans for create buttons and passes those booleans to `profile.html` instead of sending raw settings to the browser.
+
+The profile tab script renders workspace collections with safe DOM APIs. It supports pagination, search, list/card view switching, create forms, discover modals, request access actions, and active workspace selection through the existing backend APIs.
+
+### API Endpoints
+
+- `GET /api/groups`
+- `POST /api/groups`
+- `PATCH /api/groups/setActive`
+- `GET /api/groups/discover`
+- `POST /api/groups/<group_id>/requests`
+- `GET /api/public_workspaces`
+- `POST /api/public_workspaces`
+- `PATCH /api/public_workspaces/setActive`
+- `GET /api/public_workspaces/discover`
+- `POST /api/public_workspaces/<workspace_id>/requests`
+
+### Configuration Options
+
+- `enable_group_workspaces`
+- `enable_group_creation`
+- `require_member_of_create_group`
+- `enable_public_workspaces`
+- `require_member_of_create_public_workspace`
+
+### File Structure
+
+- `application/single_app/route_frontend_profile.py`
+- `application/single_app/route_frontend_groups.py`
+- `application/single_app/route_frontend_public_workspaces.py`
+- `application/single_app/templates/profile.html`
+- `application/single_app/static/js/profile/profile-tabs.js`
+- Navigation templates and workspace page redirects
+- `functional_tests/test_profile_workspace_tabs.py`
+- `ui_tests/test_profile_workspace_tabs.py`
+- `application/single_app/config.py`
+
+## Usage Instructions
+
+Users can open Profile and switch to the Groups or Public Workspaces tab. Existing menu entries for My Groups and My Public Workspaces now deep-link to those tabs. Direct requests to `/my_groups` and `/my_public_workspaces` redirect to the corresponding profile tab.
+
+Each tab includes list and card views. Users can search the collection, change page size, create new workspaces when permitted, find workspaces to join, request access, set the active workspace, and open the management page.
+
+## Testing and Validation
+
+### Test Coverage
+
+- `functional_tests/test_profile_workspace_tabs.py` validates the static routing, template, JavaScript, menu link, documentation, and version contracts.
+- `ui_tests/test_profile_workspace_tabs.py` validates that authenticated browser sessions can open the profile workspace tabs and switch between list and card views when the features are enabled.
+
+### Performance Considerations
+
+Workspace rows are loaded lazily only when a profile workspace tab is opened. Existing paginated APIs continue to control response size.
+
+### Known Limitations
+
+The UI test skips when no authenticated Playwright storage state is configured or when both workspace features are disabled in the environment.
+
+## Version Tracking
+
+Fixed/Implemented in version: **0.241.028**
+
+The application version was updated in `application/single_app/config.py` to `0.241.028` for this feature. Related tests and documentation use the same version for traceability.

+# SIMPLECHAT_CONVERSATION_MESSAGES.md
+
+# SimpleChat Conversation Messaging
+
+Implemented in version: **0.241.028**
+
+## Overview
+
+This enhancement extends the SimpleChat action so agents can do more than create conversations. They can now add a user-authored message to an existing personal or collaborative conversation, and they can optionally seed a newly created conversation with an initial message when the add-message capability is enabled.
+
+Related config update: `application/single_app/config.py` now sets `VERSION = "0.241.028"`.
+
+## Dependencies
+
+- Existing personal conversation storage in Cosmos DB
+- Existing collaborative conversation persistence and notification helpers
+- Shared SimpleChat Semantic Kernel plugin loading and capability filtering
+- Workspace action and agent capability configuration modals
+
+## Technical Specifications
+
+### Architecture Overview
+
+- Shared backend operations: `application/single_app/functions_simplechat_operations.py`
+- Built-in SK plugin: `application/single_app/semantic_kernel_plugins/simplechat_plugin.py`
+- Workspace action capability UI: `application/single_app/static/js/plugin_modal_stepper.js`
+- Agent capability UI: `application/single_app/static/js/agent_modal_stepper.js`
+
+### Runtime Behavior
+
+- New SimpleChat capability: `add_conversation_message`
+- New plugin function: `add_conversation_message(conversation_id, content, reply_to_message_id="")`
+- Personal conversation message posting writes a user message into the existing personal message container and updates the conversation timestamp and default title.
+- Collaborative conversation message posting reuses the existing collaboration authorization, persistence, and notification pipeline.
+- `create_personal_conversation`, `create_group_conversation`, and `create_personal_collaboration_conversation` now accept an optional `initial_message`.
+- Initial-message seeding is blocked unless the action instance also enables the `add_conversation_message` capability.
+
+### Capability Storage
+
+The capability continues to follow the existing SimpleChat capability map structure in action defaults and `other_settings.action_capabilities`.
+
+Example:
+
+```json
+{
+  "action_capabilities": {
+    "simplechat-action-id": {
+      "create_group": false,
+      "add_group_member": false,
+      "create_group_conversation": true,
+      "create_personal_conversation": true,
+      "add_conversation_message": true,
+      "create_personal_collaboration_conversation": false
+    }
+  }
+}
+```
+
+## Usage Instructions
+
+1. Create or edit a `Simple Chat` action.
+2. Leave `Add conversation messages` enabled for any agent that should be able to seed or append messages.
+3. Attach the action to an agent and adjust per-agent capability overrides if needed.
+4. Call either the dedicated `add_conversation_message` function or pass `initial_message` when creating a supported conversation.
+
+## Testing And Validation
+
+Functional coverage:
+
+- `functional_tests/test_simplechat_agent_action.py`
+- `functional_tests/test_simplechat_conversation_messages.py`
+
+UI coverage:
+
+- `ui_tests/test_agent_modal_simplechat_capabilities.py`
+- `ui_tests/test_workspace_simplechat_action_modal.py`
+
+Validation focus:
+
+- capability exposure in workspace and agent modals
+- runtime filtering of the new capability
+- personal conversation message persistence
+- collaborative conversation message persistence reuse
+- initial-message seeding guard behavior
+
+## Known Limitations
+
+- Initial-message seeding currently applies only to the SimpleChat create-conversation plugin functions that were extended in this change.
+- The inserted message is always written as a user-authored message in the invoking user's context.

+# Control Center Public Workspace UX Alignment (v0.241.029)
+
+Implemented in version: **0.241.029**
+
+## Overview
+
+The Control Center Public Workspace Management view now uses the same card-wrapped management table pattern as Group Management while intentionally omitting any public workspace creation disable control.
+
+## Purpose
+
+This enhancement makes public workspace administration feel consistent with group administration by aligning the table surface, sortable column affordances, loading copy, and pagination placement.
+
+## Dependencies
+
+- `application/single_app/config.py` version `0.241.029`
+- `application/single_app/templates/control_center.html`
+- `application/single_app/static/js/control-center.js`
+
+## Technical Specifications
+
+### Architecture Overview
+
+Public workspace management remains backed by `/api/admin/control-center/public-workspaces`. The template now wraps the public workspace table and pagination in the same Bootstrap card structure used by group management.
+
+### UI Behavior
+
+- Public workspace search, status filtering, export, bulk action, refresh, and page-size controls remain unchanged.
+- The table uses the shared `group-table` styling pattern for visual consistency with Group Management.
+- Workspace name, owner, members, status, and documents columns expose sortable headers.
+- No global disable switch or disable-creation button was added for public workspaces.
+
+### File Structure
+
+- Template: `application/single_app/templates/control_center.html`
+- Client behavior: `application/single_app/static/js/control-center.js`
+- Functional test: `functional_tests/test_control_center_management_pagination.py`
+- UI test: `ui_tests/test_control_center_management_pagination.py`
+
+## Usage Instructions
+
+Administrators can open Control Center, switch to Public Workspace Management, and use the table like Group Management: search, filter, change page size, sort columns, select rows, export, refresh, and manage individual workspaces.
+
+## Testing and Validation
+
+- Source-level functional regression validates matching page-size options, server-side pagination parameters, sortable public workspace headers, and absence of a disable-creation control.
+- Playwright UI regression validates the public workspace table card/sortable structure when UI environment variables are provided.
+- JavaScript syntax validation is covered with `node --check` for `control-center.js`.
+
+## Known Limitations
+
+The shared sorter is client-side and sorts only the currently loaded page of public workspaces. Server-side paging remains the source of truth for larger result sets.
+
+## Config Version Reference
+
+The application version was updated in `application/single_app/config.py` to `0.241.029` for this enhancement.

+# SIMPLECHAT_MARKDOWN_WORKSPACE_UPLOADS.md
+
+# SimpleChat Markdown Workspace Uploads
+
+Implemented in version: **0.241.029**
+
+## Overview
+
+This enhancement adds a new SimpleChat capability for creating Markdown files and uploading them into workspaces through the existing document-ingestion pipeline. It is intended for cases where an agent produces a summary, notes, or other structured output that should be saved as a searchable workspace document instead of remaining only in chat.
+
+Related config update: `application/single_app/config.py` now sets `VERSION = "0.241.029"`.
+
+## Dependencies
+
+- Existing personal workspace document upload pipeline
+- Existing group workspace document upload pipeline and group role enforcement
+- Existing Markdown document processor in `functions_documents.py`
+- Shared SimpleChat Semantic Kernel plugin loading and capability filtering
+- Workspace action and agent capability configuration modals
+
+## Technical Specifications
+
+### Architecture Overview
+
+- Shared backend operations: `application/single_app/functions_simplechat_operations.py`
+- Built-in SK plugin: `application/single_app/semantic_kernel_plugins/simplechat_plugin.py`
+- Document metadata and background ingestion: `application/single_app/functions_documents.py`
+- Workspace action capability UI: `application/single_app/static/js/plugin_modal_stepper.js`
+- Agent capability UI: `application/single_app/static/js/agent_modal_stepper.js`
+
+### Runtime Behavior
+
+- New SimpleChat capability: `upload_markdown_document`
+- New plugin function: `upload_markdown_document(file_name, markdown_content, workspace_scope="personal", group_id="")`
+- The helper writes the supplied Markdown into a temporary `.md` file and queues the existing `process_document_upload_background(...)` flow.
+- Personal uploads invalidate the personal search cache and log a normal personal document upload activity.
+- Group uploads enforce the same upload rules as the group document route:
+  - group existence check
+  - group status `upload` allowance
+  - `Owner`, `Admin`, or `DocumentManager` role requirement
+- Group uploads can target an explicit `group_id`, the action's `default_group_id`, or the user's active group when group scope is requested.
+
+### Capability Storage
+
+The new capability follows the existing SimpleChat capability map structure in action defaults and `other_settings.action_capabilities`.
+
+Example:
+
+```json
+{
+  "action_capabilities": {
+    "simplechat-action-id": {
+      "create_group": false,
+      "add_group_member": false,
+      "create_group_conversation": true,
+      "create_personal_conversation": true,
+      "add_conversation_message": true,
+      "upload_markdown_document": true,
+      "create_personal_collaboration_conversation": false
+    }
+  }
+}
+```
+
+## Usage Instructions
+
+1. Create or edit a `Simple Chat` action.
+2. Leave `Upload markdown documents` enabled for any agent that should be able to save generated summaries or notes into a workspace.
+3. Call `upload_markdown_document` with a file name and Markdown content.
+4. Use `workspace_scope="personal"` for the personal workspace, or `workspace_scope="group"` with a target group when the output should be stored in a group workspace.
+
+## Testing And Validation
+
+Functional coverage:
+
+- `functional_tests/test_simplechat_agent_action.py`
+- `functional_tests/test_simplechat_markdown_upload.py`
+
+UI coverage:
+
+- `ui_tests/test_agent_modal_simplechat_capabilities.py`
+- `ui_tests/test_workspace_simplechat_action_modal.py`
+
+Validation focus:
+
+- capability exposure in workspace and agent modals
+- runtime filtering of the new capability
+- personal Markdown upload queueing through the existing document processor
+- group Markdown upload queueing with normal group permission checks
+- plugin forwarding of default group context
+
+## Known Limitations
+
+- This capability currently supports Markdown documents only.
+- Upload processing remains asynchronous, so the action returns a queued document record rather than waiting for indexing to finish.

+# Control Center Management ID Search (v0.241.030)
+
+Implemented in version: **0.241.030**
+
+## Overview
+
+Control Center management searches now include IDs for users, groups, and public workspaces. The search placeholders were updated so administrators know they can search by ID as well as the existing readable labels.
+
+## Purpose
+
+Administrators often need to locate a specific record from logs, URLs, exports, or support requests where only an object ID is available. This enhancement makes the management tabs usable for that workflow without requiring manual database lookup.
+
+## Dependencies
+
+- `application/single_app/config.py` version `0.241.030`
+- `application/single_app/route_backend_control_center.py`
+- `application/single_app/templates/control_center.html`
+
+## Technical Specifications
+
+### Search Coverage
+
+- User Management searches `id`, `email`, and `display_name`.
+- Group Management searches `id`, `name`, `description`, and owner fields.
+- Public Workspace Management searches `id`, `name`, `description`, and owner fields.
+
+### API Endpoints
+
+- `/api/admin/control-center/users`
+- `/api/admin/control-center/groups`
+- `/api/admin/control-center/public-workspaces`
+
+## Usage Instructions
+
+Open Control Center and use the existing search box on User Management, Group Management, or Public Workspace Management. Enter a full or partial ID to filter the table results.
+
+## Testing and Validation
+
+- Functional regression: `functional_tests/test_control_center_management_pagination.py`
+- UI regression: `ui_tests/test_control_center_management_pagination.py`
+- Validation includes ID-aware placeholders and backend search clauses.
+
+## Known Limitations
+
+Search remains a substring match against the fields included by each management API. It does not perform fuzzy matching or cross-tab lookup.
+
+## Config Version Reference
+
+The application version was updated in `application/single_app/config.py` to `0.241.030` for this enhancement.

+# SIMPLECHAT_WORKFLOWS_AND_GROUP_STATUS.md
+
+# SimpleChat Workflows And Group Status
+
+Implemented in version: **0.241.030**
+
+## Overview
+
+This enhancement adds two new SimpleChat capabilities that let an agent act through the signed-in user's own permissions for automation and administrative tasks:
+
+- Create personal workflows through the existing personal workflow engine.
+- Mark groups inactive through the same Control Center admin permission boundary used by the existing group status management UI.
+
+Related config update: `application/single_app/config.py` now sets `VERSION = "0.241.030"`.
+
+## Dependencies
+
+- Existing SimpleChat capability filtering and plugin loading
+- Existing personal workflow storage and validation in `functions_personal_workflows.py`
+- Existing Control Center group status model and audit logging
+- Workspace action and agent capability configuration modals
+
+## Technical Specifications
+
+### Architecture Overview
+
+- Shared backend operations: `application/single_app/functions_simplechat_operations.py`
+- Built-in SK plugin: `application/single_app/semantic_kernel_plugins/simplechat_plugin.py`
+- Personal workflow persistence: `application/single_app/functions_personal_workflows.py`
+- Group activity audit logging: `application/single_app/functions_activity_logging.py`
+- Workspace action capability UI: `application/single_app/static/js/plugin_modal_stepper.js`
+- Agent capability UI: `application/single_app/static/js/agent_modal_stepper.js`
+
+### New SimpleChat Capabilities
+
+- `create_personal_workflow`
+  - Creates a personal workflow under the current user's identity.
+  - Reuses `save_personal_workflow(...)` so the same runner validation, schedule validation, model binding, and selected-agent checks apply as the normal workflow UI.
+  - Supports both `model` and `agent` runners and both `manual` and `interval` triggers.
+
+- `make_group_inactive`
+  - Marks a group `inactive` and records status history.
+  - Reuses the same Control Center admin access boundary as the existing admin route:
+    - If `require_member_of_control_center_admin` is enabled, the caller must have `ControlCenterAdmin`.
+    - Otherwise, the caller must have `Admin`.
+  - Logs the group status change through the existing activity log helper.
+
+### Group Resolution Behavior
+
+For `make_group_inactive`, the target group is resolved in this order:
+
+1. Explicit `group_id`
+2. Action `default_group_id`
+3. The user's active group setting
+
+## Usage Instructions
+
+1. Create or edit a `Simple Chat` action.
+2. Leave `Create personal workflows` enabled for agents that should be able to save automation jobs for the current user.
+3. Leave `Make groups inactive` enabled only where the current user should be allowed to invoke Control Center-style group status changes.
+4. Call `create_personal_workflow` with a workflow name, task prompt, runner type, and optional schedule or model selection.
+5. Call `make_group_inactive` with a target `group_id` or rely on the current group context when appropriate.
+
+## Testing And Validation
+
+Functional coverage:
+
+- `functional_tests/test_simplechat_agent_action.py`
+- `functional_tests/test_simplechat_workflow_and_group_inactive.py`
+
+UI coverage:
+
+- `ui_tests/test_agent_modal_simplechat_capabilities.py`
+- `ui_tests/test_workspace_simplechat_action_modal.py`
+
+Validation focus:
+
+- runtime overlay exposure of the new capability names
+- workflow payload mapping into the existing personal workflow store
+- admin-only permission enforcement for group inactivity
+- status history and audit logging for inactive transitions
+- modal visibility and persistence of the new capability toggles
+
+## Known Limitations
+
+- The SimpleChat workflow capability currently creates personal workflows only; it does not edit or delete existing workflows.
+- The group status capability only marks groups inactive; it does not expose other Control Center status transitions through SimpleChat.

+# Conversation Chart and Tabular Reuse - v0.241.031
+
+## Overview
+
+Implemented in version: **0.241.031**
+
+This feature makes the built-in chart action available as a core conversation ability and adds a reusable tabular analysis import surface for workflow execution. Users can ask for charts directly in conversation, while agents can still be assigned chart actions for workflow-oriented tool use.
+
+## Dependencies
+
+- `application/single_app/config.py` version `0.241.031`
+- Semantic Kernel plugin loading in `application/single_app/semantic_kernel_loader.py`
+- Built-in chart plugin in `application/single_app/semantic_kernel_plugins/chart_plugin.py`
+- Tabular chat analysis helpers currently implemented in `application/single_app/route_backend_chats.py`
+
+## Technical Specifications
+
+### Architecture
+
+- The conversation-level chart plugin is registered under the non-colliding core plugin name `conversation_charts`.
+- Assigned chart actions remain supported through normal action manifests and per-agent `actions_to_load` behavior.
+- Workflow tabular document actions now import reusable helpers through `functions_tabular_analysis.py` instead of importing the chat route directly.
+
+### File Structure
+
+- `application/single_app/functions_chart_operations.py` defines the shared core chart plugin name.
+- `application/single_app/semantic_kernel_loader.py` loads the chart plugin in model-only, global, and per-user kernel paths.
+- `application/single_app/functions_tabular_analysis.py` provides the workflow-facing tabular helper surface.
+- `application/single_app/functions_workflow_runner.py` consumes tabular helpers through the reusable module.
+
+## Usage Instructions
+
+Users can ask for charts in chat with prompts such as “make a bar chart of revenue by month.” The chat route now adds chart-tool guidance for chart requests even when no selected agent is active.
+
+Agents can still be configured with chart actions when workflow authors want charting available as an explicit assigned tool.
+
+## Testing and Validation
+
+Functional coverage is provided by `functional_tests/test_conversation_chart_and_tabular_reuse.py`.
+
+The test validates:
+
+- The app version was updated to `0.241.031`.
+- The chart plugin is loaded as a core conversation ability.
+- Chart prompt guidance applies without a selected agent.
+- Workflow tabular execution imports a reusable tabular analysis module.
+
+## Known Limitations
+
+The reusable tabular module is currently a lazy compatibility surface over chat-route implementations. This keeps the runtime behavior stable while creating a dedicated module boundary for a future deeper extraction of the tabular analysis implementation.

+# Prompt Card Views
+
+## Overview
+
+Prompt card views add a card/list display switcher to prompt tabs across personal, group, and public workspaces. The card layout gives prompts the same scannable treatment already used by workspace documents while keeping the existing table/list workflow available.
+
+## Implemented In Version
+
+Implemented in version: **0.241.031**
+
+This feature uses the application version tracked in `application/single_app/config.py`.
+
+## Dependencies
+
+- Bootstrap 5 tabs, buttons, cards, dropdowns, and modals
+- Bootstrap Icons for list, card, prompt, run, activity, history, edit, and delete actions
+- Existing prompt APIs for personal, group, and public workspace scopes
+- Existing shared personal workspace modal helper for personal prompt quick view
+
+## Technical Specifications
+
+### Architecture Overview
+
+- Personal prompt list/card switching is handled in `application/single_app/static/js/workspace/workspace-prompts.js` using the shared workspace view helper pattern.
+- Group prompt cards are rendered by inline group workspace JavaScript in `application/single_app/templates/group_workspaces.html` because that page owns its prompt UI locally.
+- Public prompt cards are rendered by `application/single_app/static/js/public/public_workspace.js` and use a dedicated public prompt details modal.
+- Shared prompt card sizing and preview styles live in `application/single_app/static/css/workspace-responsive.css`.
+
+### User Interface Behavior
+
+- Prompt tabs now expose list and card toggle controls in personal, group, and public workspaces.
+- Prompt cards show prompt name, a short content preview, and action buttons.
+- Clicking a prompt card body opens prompt details.
+- Prompt action buttons stop card-click propagation so view, edit, and delete commands remain explicit.
+- Workflow cards now open the edit modal when the card body is clicked or activated from the keyboard.
+- Workflow cards show Run and Activity as primary actions, with Run, Activity, History, Edit, and Delete in a three-dot overflow menu.
+
+### API Endpoints
+
+The feature uses existing endpoints:
+
+- `GET /api/prompts`
+- `GET /api/prompts/<prompt_id>`
+- `GET /api/group_prompts`
+- `GET /api/group_prompts/<prompt_id>`
+- `GET /api/public_prompts`
+- `GET /api/public_prompts/<prompt_id>`
+
+## Usage Instructions
+
+1. Open a personal, group, or public workspace.
+2. Select the Prompts tab.
+3. Use the list/card toggle to switch views.
+4. Click a prompt card body to inspect the prompt details.
+5. Use the card action buttons to view, edit, or delete prompts when permitted by the current workspace role.
+6. In personal Workflows, switch to card view, click a workflow card body to edit it, or use the visible Run/Activity buttons and overflow menu for other actions.
+
+## Testing And Validation
+
+### Test Coverage
+
+- `ui_tests/test_workspace_workflow_prompt_ui_refresh.py` validates personal prompt card rendering, prompt quick view, workflow card primary actions, the workflow overflow menu, and card-click edit behavior.
+- `ui_tests/test_workspace_prompt_card_views.py` validates group and public prompt card rendering plus card-open prompt detail behavior.
+
+### Validation Results

+# Prompt Chat Buttons
+
+## Overview
+
+Prompt Chat buttons let users jump from workspace prompt management directly into Chats with the selected prompt already active. The behavior is available for personal, group, and public workspace prompts.
+
+## Implemented In Version
+
+Implemented in version: **0.241.032**
+
+This feature uses the application version tracked in `application/single_app/config.py`.
+
+## Dependencies
+
+- Existing personal, group, and public prompt APIs
+- Existing Chats prompt selector and prompt catalog injected by `route_frontend_chats.py`
+- Bootstrap buttons, cards, and modals
+- Existing workspace prompt list/card rendering
+
+## Technical Specifications
+
+### Architecture Overview
+
+- Personal prompts build Chat links in `application/single_app/static/js/workspace/workspace-prompts.js`.
+- Group prompts build scoped Chat links in `application/single_app/templates/group_workspaces.html` using the active group id.
+- Public prompts build scoped Chat links in `application/single_app/static/js/public/public_workspace.js` using the active public workspace id.
+- Chats consumes `prompt_id`, `prompt_scope`, and optional `prompt_scope_id`, `group_id`, or `workspace_id` query parameters in `application/single_app/static/js/chat/chat-onload.js`.
+- Prompt selection is performed by `selectPromptById(...)` in `application/single_app/static/js/chat/chat-prompts.js`.
+
+### Query Parameters
+
+Prompt Chat links use these parameters:
+
+- `prompt_id`: selected prompt id
+- `prompt_scope`: `personal`, `group`, or `public`
+- `prompt_scope_id`: group id or public workspace id when applicable
+- `group_id`: group workspace id for group prompt links
+- `workspace_id`: public workspace id for public prompt links
+- `openPrompt=1`: indicates that the prompt picker should open on the Chats page
+
+## Usage Instructions
+
+1. Open a personal, group, or public workspace.
+2. Go to the Prompts tab.
+3. Select Chat from a prompt row, prompt card, or prompt details modal.
+4. The Chats page opens with the prompt picker visible and the originating prompt selected.
+5. Send the prompt as-is or add extra text before sending.
+
+## Testing And Validation
+
+### Test Coverage
+
+- `ui_tests/test_workspace_workflow_prompt_ui_refresh.py` validates the personal prompt Chat button in list, card, and details modal surfaces and verifies the generated Chat URL contains the prompt selection parameters.
+- `ui_tests/test_workspace_prompt_card_views.py` validates group and public prompt Chat buttons in list, card, and details modal surfaces.
+
+### Validation Results
+
+- JavaScript syntax checks cover the changed prompt, public workspace, and chat initialization modules.
+- UI tests are included for the browser surfaces that expose the new prompt Chat action.
+
+### Known Limitations
+
+- Browser execution of the full Chats deep-link selection requires an authenticated Playwright storage state and a running SimpleChat instance with matching prompt catalog data.

+# Proactive Analytical Charts
+
+Implemented in version: **0.241.033**
+
+## Overview
+
+Proactive Analytical Charts extends the conversation-level chart capability so chat responses and workflow outputs can include charts whenever the available data supports useful visualization. Users no longer need to explicitly say "make a chart" when asking for analysis, comparison, reports, Markdown output, or presentation-ready content.
+
+## Purpose
+
+The feature makes charts part of the generated analytical output instead of a final add-on. When the model identifies chart-worthy numeric or categorical patterns, it is guided to create inline charts near the relevant section, table, or finding.
+
+## Dependencies
+
+- Conversation chart plugin loaded as `conversation_charts`
+- Inline chart markdown language: `simplechart`
+- Tabular analysis handoff messages and workflow synthesis prompts
+- PowerPoint and Markdown export paths that preserve inline chart blocks
+
+## Technical Specifications
+
+### Architecture
+
+- `functions_chart_operations.py` owns reusable proactive chart guidance helpers.
+- `route_backend_chats.py` applies chart guidance for explicit chart requests and analytical output requests such as reports, comparisons, Markdown, and PowerPoint prompts.
+- `functions_workflow_runner.py` applies the same guidance to tabular analyze/compare synthesis and general workflow generation prompts.
+
+### Chart Selection Guidance
+
+- Line or area charts for time trends
+- Bar charts for category comparisons
+- Stacked bar or stacked line charts for composition across groups or time
+- Doughnut or pie charts for small part-to-whole splits
+- Scatter or bubble charts for relationships between numeric measures
+- Radar charts for compact multi-metric profiles
+
+### Output Placement
+
+Charts should be inserted inline immediately after the section, paragraph, or table they support. Comprehensive reviews can include multiple high-value charts when multiple distinct patterns exist.
+
+## Usage Instructions
+
+Users can ask for natural analytical outputs such as:
+
+- "Analyze this workbook and create an executive summary."
+- "Compare these quarterly sales files."
+- "Develop a PowerPoint presentation from this dataset."
+- "Generate a Markdown report from these metrics."
+
+The model should decide whether charts are useful, how many charts to include, and which chart type fits each data shape.
+
+## Testing and Validation
+
+Functional coverage:
+
+- `functional_tests/test_conversation_chart_and_tabular_reuse.py`
+- `functional_tests/test_chart_tool_prompt_handoff.py`
+
+Validation focuses on:
+
+- Core chart plugin availability in conversation paths
+- Proactive chart guidance for analytical chat prompts
+- Workflow prompt wiring for tabular and general workflow generation
+- Kernel fallback auto tool invocation for conversation tools
+
+## Known Limitations
+
+Direct model-only workflow generation cannot call Semantic Kernel tools directly, so the prompt allows valid `simplechart` blocks when no chart action/tool is available. Agent-backed and kernel-backed paths should prefer chart tool calls when available.

+# SimpleChat Group Conversation Member Invites
+
+Implemented in version: **0.241.038**
+
+Related config update:
+- `application/single_app/config.py` now reports version `0.241.038`.
+
+## Overview
+
+This enhancement adds a dedicated SimpleChat capability for inviting current group members into an existing invite-managed group multi-user conversation. It complements `create_group_conversation` so an agent can first create the shared conversation and then explicitly add the right participants through the same collaboration permission model already used by the backend APIs.
+
+## Dependencies
+
+- `application/single_app/functions_simplechat_operations.py`
+- `application/single_app/semantic_kernel_plugins/simplechat_plugin.py`
+- `application/single_app/functions_collaboration.py`
+- `application/single_app/static/js/plugin_modal_stepper.js`
+- `application/single_app/static/js/agent_modal_stepper.js`
+
+## Technical Specifications
+
+Architecture overview:
+- New SimpleChat capability key: `invite_group_conversation_members`
+- New SimpleChat plugin function: `invite_group_conversation_members(conversation_id, participant_identifiers="")`
+- The helper resolves participant identifiers through the existing directory lookup path and normalizes them into collaboration-user summaries before reusing `invite_personal_collaboration_participants(...)`.
+
+Runtime behavior:
+- `conversation_id` must point at a group multi-user collaborative conversation.
+- Only invite-managed group conversations support member invitations.
+- Only current members of the underlying group can be invited.
+- The acting user still has to be a conversation owner or conversation admin.
+- The capability returns the updated conversation plus the invited participant summaries and a result message suitable for agent follow-up.
+
+Capability storage:
+- The capability follows the existing SimpleChat capability map in both action defaults and agent-level overrides.
+- Workspace and agent modals now expose a dedicated toggle labeled `Invite group conversation members`.
+
+## Usage Instructions
+
+1. Enable `Create group multi-user conversations` when the agent needs to start the shared conversation.
+2. Enable `Invite group conversation members` when the agent also needs to add participants afterward.
+3. Call `create_group_conversation` to create the invite-managed conversation.
+4. Call `invite_group_conversation_members` with the resulting `conversation_id` and one or more emails, UPNs, or user IDs separated by commas or new lines.
+
+## Testing And Validation
+
+Functional coverage:
+- `functional_tests/test_simplechat_group_conversation_member_invites.py`
+- `functional_tests/test_simplechat_agent_action.py`
+- `functional_tests/test_simplechat_group_multi_user_conversation.py`
+
+UI coverage:
+- `ui_tests/test_workspace_simplechat_action_modal.py`
+- `ui_tests/test_agent_modal_simplechat_capabilities.py`
+
+Validation focus:
+- backend invite payload construction
+- rejection for non-group conversations
+- plugin metadata and forwarding
+- workspace and agent capability toggle visibility and persistence

+# Workflow Activity View
+
+Implemented in version: **0.241.039**
+
+## Overview
+
+The workflow activity view adds a dedicated execution timeline for workflow runs.
+It gives users a live and historical view of what a workflow is doing, including
+workflow lifecycle events, tool invocations, and direct model execution stages.
+
+## Dependencies
+
+- Workflow conversations in the shared conversations container
+- Workflow run history in `personal_workflow_runs`
+- Thought persistence in the existing `thoughts` container
+- Server-sent events for live updates while a run is active
+
+## Technical Specifications
+
+### Architecture
+
+- The feature reuses the existing `thoughts` container instead of introducing a new Cosmos container.
+- Workflow runs now allocate the assistant message id before execution so live activity can attach to the run immediately.
+- Tool invocation start and completion events share a stable `invocation_id`, which lets the activity page merge them into a single timeline card.
+- The new workflow activity page is served from `/workflow-activity`.
+
+### Backend Endpoints
+
+- `GET /api/user/workflows/activity`
+  - Resolves the latest run for a workflow conversation or a specific historical run.
+  - Returns the merged workflow activity snapshot used by the page.
+- `GET /api/user/workflows/activity/stream`
+  - Streams refreshed workflow activity snapshots over SSE while a run is active.
+
+### Frontend Entry Points
+
+- Workflow conversations show an `Activity View` button in the chat header.
+- Workflow run history now includes `Open activity view` links for each recorded run.
+
+## Usage
+
+1. Open a workflow conversation and select `Activity View` to inspect the latest run in a new tab.
+2. Open workflow history from the workspace workflows tab and use `Open activity view` on a specific run to inspect the historical snapshot.
+3. While a workflow is still running, keep the activity page open to receive live timeline updates over SSE.
+
+## Testing and Validation
+
+- Functional test: `functional_tests/test_workflow_activity_view_feature.py`
+- The snapshot builder verifies activity merging, branch lane assignment, and fallback rendering for legacy runs without structured activity thoughts.
+- The workflow page renders without introducing a new storage dependency.

+# Document Analysis Lossless Artifacts
+
+## Overview
+
+Version: 0.241.040
+
+Fixed/Implemented in version: **0.241.040**
+
+Related config.py update: `application/single_app/config.py` now sets `VERSION = "0.241.040"`.
+
+This enhancement changes exhaustive document analysis requests so successful window-level work is retained and packaged into durable artifacts. When users ask to list, find, extract, inventory, or make a table from selected documents, SimpleChat now keeps raw analysis notes and prepares structured CSV plus Markdown analysis artifacts instead of relying only on the reduced final answer.
+
+Dependencies: `functions_document_analysis.py`, `functions_workflow_runner.py`, generated chat artifacts, and existing document action workflow execution.
+
+## Technical Specifications
+
+Architecture overview:
+The document analysis service now classifies exhaustive/table-style requests with deterministic guardrails and returns `analysis_intent`, `raw_analysis_items`, and `document_analysis_items` alongside the final reduced answer and coverage metadata.
+
+Artifact generation:
+The workflow runner uses the returned intent metadata to create lossless artifacts for exhaustive outputs:
+
+- CSV artifact: extracted JSON rows or Markdown table rows from retained raw/window outputs, with source document and window metadata appended.
+- Markdown artifact: final analysis, coverage summary, and retained raw window-level or document-level analysis notes.
+- JSON artifact: preserved when the final analysis is valid JSON.
+
+Reduction behavior:
+Reduction still produces a readable analytical summary, but it is no longer the only surviving output for extraction/table requests. The retained artifacts become the audit trail for the work already performed.
+
+Configuration:
+No new administrator setting is required. The version was bumped in `application/single_app/config.py` for traceability.
+
+## Usage Instructions
+
+User workflow:
+Select documents and ask an exhaustive analysis question such as:
+
+- "List all vendors and services being performed."
+- "Make a table of every entity and amount."
+- "Extract all contract risks into rows."
+
+Expected output:
+The assistant response includes a concise summary and preview, while the chat receives generated artifacts containing the full structured rows and the full Markdown analysis/raw notes.
+
+## Testing And Validation
+
+Functional coverage:
+`functional_tests/test_document_analysis_lossless_artifacts.py` verifies that exhaustive table prompts preserve raw window outputs, produce structured CSV rows from retained Markdown tables, render a Markdown artifact with raw notes, and keep version alignment with `config.py`.
+
+Performance considerations:
+Retained raw analysis is already produced during normal window processing, so this feature avoids extra document reads. Artifact size remains bounded by the existing generated chat artifact size limit.
+
+Known limitations:
+CSV extraction is schema-agnostic. It can parse JSON arrays/objects and Markdown tables from model outputs, but if a window returns only prose, that prose is retained as an `analysis_note` row instead of being force-shaped into a domain-specific schema.

+# Source Review
+
+Implemented in version: **0.241.041**
+
+Refined in version: **0.241.042**
+
+Planner refinement in version: **0.241.043**
+
+Traversal observability refinement in version: **0.241.044**
+
+Citation seeding and second-hop traversal refinement in version: **0.241.045**
+
+Rendered Load More refinement in version: **0.241.046**
+
+## Overview
+
+Source Review adds an optional chat control that lets SimpleChat inspect source pages directly instead of relying only on search result snippets. It is designed to work with Web Search by using returned citation URLs as review seeds, and it can also review URLs pasted directly in a user's message.
+
+Deep Source Review can follow a bounded set of relevant links from a listing or index page, such as press release indexes, RSS feeds, sitemap entries, or source pages that point to detail pages. Reviewed content is packaged as untrusted evidence and added to the model context with explicit prompt-injection isolation instructions.
+
+The v0.241.042 refinement keeps seed/archive pages ahead of child pages in the page budget, then uses leftover budget for the highest-scoring child links across all reviewed seed pages. This avoids over-investing in the first source page when a request spans multiple organizations, products, or official archives.
+
+The v0.241.043 refinement adds optional model-assisted link planning for Deep Source Review. After seed pages are reviewed and child links are extracted, the selected chat model can rank only those already-extracted candidate URLs before the server fetches additional pages. The planner cannot browse, invent fetch targets, or bypass Source Review URL policy; if planning is unavailable or returns unusable URLs, deterministic child-link ordering remains the fallback.
+
+The v0.241.044 refinement scores extracted links before applying the bounded link inventory limit. This keeps relevant press-release, archive, and source-detail links available even when source pages contain long navigation menus before the actual evidence links. It also expands Source Review audit output so logs show whether Deep Source Review and model-assisted planning were actually used.
+
+The v0.241.045 refinement sends all Foundry web-search URL citations into Source Review, not just links repeated in the web-search answer text. It also adds a configurable seed-page budget and raises bounded Deep Source Review depth to `2`, so official source pages can be inspected through one additional section or year page before reaching detail pages.
+
+The v0.241.046 refinement adds optional Load More support to the rendered-page path. When JavaScript rendering is enabled and a source page exposes visible Load More, Show More, View More, or similar controls, Source Review can click them up to a configured cap before extracting evidence. The renderer stops early when no new content appears or the requested date range appears visible.
+
+## Dependencies
+
+Source Review uses server-side HTTP requests through `aiohttp` and HTML/XML extraction through `beautifulsoup4`, both already present in the application requirements. Optional JavaScript rendering is available only when admins enable it and the app host has a Playwright browser runtime installed.
+
+## Technical Specifications
+
+### Architecture
+
+The implementation is centered in `application/single_app/functions_source_review.py` and is invoked from `application/single_app/route_backend_chats.py` after Web Search runs. This ordering lets the feature review both user-provided URLs and Web Search citation URLs before the final model response is generated.
+
+The chat route appends Source Review output as a system augmentation message. The message clearly labels page content as untrusted web evidence and directs the model to ignore instructions found inside fetched pages.
+
+### Server-Side Protections
+
+These protections are enforced in code and are not user configurable:
+
+* Only `http` and `https` URLs are allowed.
+* URL credentials are blocked.
+* Localhost, single-label hostnames, private/internal/link-local/multicast/reserved IPs, and metadata endpoints are blocked.
+* DNS-resolved addresses are checked before fetch.
+* Every redirect target is revalidated.
+* Unsupported content types are skipped.
+* Page size, redirect count, timeout, depth, and total pages are bounded by hard ceilings.
+* Web page text is never treated as tool instructions or policy text.
+
+### Configurable Settings
+
+Admins can configure Source Review in **Admin Settings > Search & Extract**:
+
+* Enable Source Review.
+* Enable Deep Source Review.
+* Enable model-assisted link planning for Deep Source Review.
+* Default mode: manual toggle, automatic for pasted URLs, or automatic with URLs/Web Search.
+* Max pages per turn, max seed pages per turn, timeout, redirect count, max MB per page, and depth.
+* Optional JavaScript rendering fallback.
+* Rendered Load More click cap.
+* robots.txt handling.
+* Domain allowlist and blocklist.
+* User allowlist and blocklist.
+* Audit logging.
+
+The app version was updated in `application/single_app/config.py` to `0.241.041` with this implementation.
+
+The traversal refinement updated `application/single_app/config.py` to `0.241.042`.
+
+The model-assisted link planning refinement updated `application/single_app/config.py` to `0.241.043`.
+
+The link-prioritization and audit refinement updated `application/single_app/config.py` to `0.241.044`.
+
+The citation seeding and second-hop traversal refinement updated `application/single_app/config.py` to `0.241.045`.
+
+The rendered Load More refinement updated `application/single_app/config.py` to `0.241.046`.
+
+## Usage Instructions
+
+Admins enable Source Review from the Search & Extract settings tab. Once enabled for a user, the chat toolbar shows a **Sources** button. Users can toggle it when they want the system to review actual pages behind pasted URLs or Web Search citations.
+
+Source Review works best when the user includes a specific source URL, asks for the latest item from an official listing page, or combines Web Search with Source Review for broad discovery plus source inspection.
+
+## Testing and Validation
+
+Functional coverage was added in `functional_tests/test_source_review_security.py` for:
+
+* User allowlist/blocklist behavior.
+* Hard clamping of admin limits.
+* SSRF-sensitive URL rejection.
+* HTML extraction, link inventory, date extraction, and prompt-injection marker detection.
+* Seed URL ordering from direct URLs and Web Search citations.
+
+Additional coverage was added in `functional_tests/test_source_review_deep_traversal.py` for generic archive-style child-link prioritization and cross-seed child selection.
+
+The v0.241.043 coverage extends `functional_tests/test_source_review_deep_traversal.py` to validate that model planning accepts only existing candidate URLs, ignores invented URLs, and preserves planner-selected ordering before deterministic fallback candidates.
+
+The v0.241.044 coverage extends `functional_tests/test_source_review_deep_traversal.py` to validate that relevant archive links survive noisy navigation before truncation and that generic same-domain navigation links are not followed for source-archive requests.
+
+The v0.241.045 coverage extends `functional_tests/test_web_search_current_message_only.py` to validate that raw Foundry citations become Source Review seed candidates, and extends `functional_tests/test_source_review_deep_traversal.py` to validate bounded second-hop traversal and seed-page budgeting.
+
+The v0.241.046 coverage extends `functional_tests/test_source_review_security.py` to validate Load More detection and click-cap clamping.
+
+UI coverage was added in `ui_tests/test_admin_source_review_settings.py` for the admin Source Review panel and bounded controls.
+
+## Known Limitations
+
+Source Review is intentionally bounded and is not a general crawler. Deep review follows only selected scored links within the configured page and depth budgets. JavaScript rendering and Load More clicks depend on optional runtime support and are treated as a fallback rather than the default fetch path.

+# File Sync Capability
+
+Implemented in version: **0.241.042**
+
+## Overview
+
+File Sync lets workspace managers configure SMB sources that copy remote files into SimpleChat document workspaces. The first implementation supports personal, group, and public workspaces with one-way sync from SMB into SimpleChat.
+
+Fixed/Implemented in version: **0.241.042**
+
+Related config.py version update: `application/single_app/config.py` was updated to `0.241.042`.
+
+## Dependencies
+
+- Redis Cache must be enabled before File Sync can be enabled.
+- SMB access uses `smbprotocol`.
+- Key Vault secret storage is used for SMB passwords when `enable_key_vault_secret_storage` and `key_vault_name` are configured.
+- Existing document ingestion, versioning, tagging, search indexing, and activity logging services are reused.
+
+## Technical Specifications
+
+### Architecture
+
+- File Sync source records are stored in scope-specific Cosmos containers partitioned by the owning workspace id.
+- File Sync item state and run history are stored in scope-specific containers partitioned by `source_id`.
+- The backend never treats `source_id` as an authorization boundary. Routes resolve the active user/workspace context and then read the source from the expected partition.
+- Scheduled runs are coordinated by the existing Cosmos-backed distributed background task lock.
+
+### Cosmos Containers
+
+- `personal_file_sync_sources`, partition `/user_id`
+- `group_file_sync_sources`, partition `/group_id`
+- `public_file_sync_sources`, partition `/public_workspace_id`
+- `personal_file_sync_items`, `group_file_sync_items`, `public_file_sync_items`, partition `/source_id`
+- `personal_file_sync_runs`, `group_file_sync_runs`, `public_file_sync_runs`, partition `/source_id`
+
+### API Endpoints
+
+- Personal: `/api/file-sync/personal/sources`
+- Group: `/api/file-sync/group/sources`
+- Public: `/api/file-sync/public/<public_workspace_id>/sources`
+- Source update/delete/sync/history endpoints are available below each source route.
+
+### Configuration
+
+Admin settings include:
+
+- Global enable/disable toggle
+- Per-scope toggles for personal, group, and public workspaces
+- Allow/block lists for users, groups, and public workspaces
+- Per-workspace source limit
+- Minimum schedule interval
+- Max files and bytes per run
+- Concurrent run limit
+- Default remote-delete policy
+- File Sync debug logging toggle
+
+## Usage Instructions
+
+1. Enable and configure Redis Cache in Admin Settings.
+2. Enable File Sync in Admin Settings.
+3. Enable the desired workspace scopes and optional allow/block lists.
+4. Open a workspace Sync tab.
+5. Add an SMB source with UNC path, credentials, filters, tags, and optional schedule.
+6. Run Sync manually or let the scheduler pick up due sources.
+
+## Sync Behavior
+
+- New remote files create new SimpleChat documents.
+- Changed remote files create new SimpleChat document versions through the existing same-name upload versioning behavior.
+- Tags can be assigned directly and derived from parent or full folder paths.
+- Include/exclude patterns and file type filters restrict which files are ingested.
+- Remote deletes never delete the SMB file. Depending on policy, SimpleChat can keep its copy or hard-delete its synced copy.
+- Deleting a synced SimpleChat document can mark the remote path ignored so it does not return on the next sync.
+
+## Testing and Validation
+
+- Functional test: `functional_tests/test_file_sync_capability.py`
+- UI test: `ui_tests/test_workspace_file_sync_ui.py`
+- Syntax checks were run for changed Python files with `python -m py_compile`.
+- JavaScript syntax checks were run with `node --check`.
+
+## Known Limitations
+
+- The first implementation supports SMB only.
+- Sync is one-way from SMB to SimpleChat.
+- Sync execution happens in the app process scheduler/executor; the helper module is structured so it can move to an external worker later.

+# Workflow Activity Response Preview Toggle
+
+Version implemented: **0.241.042**
+
+## Overview
+
+The workflow activity page now keeps the response preview collapsed by default and exposes a top-level toggle button so users can open it only when needed. This preserves more vertical space for the live timeline and the right-side activity detail panel.
+
+## Dependencies
+
+- `application/single_app/templates/workflow_activity.html`
+- `application/single_app/static/js/workflow/workflow-activity.js`
+- `application/single_app/static/css/workflow-activity.css`
+
+## Technical Specifications
+
+### Architecture Overview
+
+The response preview remains part of the workflow activity hero section, but the page now drives its visibility through a dedicated client-side toggle state. The toggle only appears when a response preview or run error exists.
+
+### Configuration And File Structure
+
+- The page template defines the toggle button and keeps the preview region wired with `aria-controls`.
+- The workflow activity script tracks whether the preview is expanded and keeps it collapsed by default.
+- The activity stylesheet rotates the toggle chevron when the preview is expanded.
+
+## Usage Instructions
+
+- Open any workflow activity page that has a response preview or captured run error.
+- Use the `Show response preview` button in the top action row to expand the preview.
+- Use the same button again to collapse it and restore more room for the timeline and details.
+
+## Testing And Validation
+
+- Regression coverage is provided by `functional_tests/test_workflow_activity_response_preview_toggle.py`.
+- Existing workflow activity snapshot coverage remains in `functional_tests/test_workflow_activity_view_feature.py`.
+- The feature is intended to improve live monitoring ergonomics without changing workflow activity data or SSE behavior.

+# Workspace Workflow And Prompt UI Refresh
+
+Implemented in version: **0.241.044**
+
+## Overview
+
+The personal workspace now uses a more consistent action language across workflows, prompts, and agents. Workflows gained the same list or grid presentation pattern already used by agents and actions, workflow actions now use clearer button roles, prompts gained a read-only quick-view action, and agent chat actions now use the filled chat treatment used elsewhere in the app.
+
+## Dependencies
+
+- `application/single_app/templates/workspace.html`
+- `application/single_app/static/js/workspace/workspace_workflows.js`
+- `application/single_app/static/js/workspace/workspace-prompts.js`
+- `application/single_app/static/js/workspace/workspace_agents.js`
+- `application/single_app/static/js/workspace/view-utils.js`
+
+## Technical Specifications
+
+### Workflow workspace updates
+
+- Removed the redundant workflows heading inside the tab while keeping the descriptive helper text.
+- Moved the `New Workflow` button to the left side of the toolbar.
+- Added list and grid view controls so workflows match the agents and actions presentation model.
+- Refreshed workflow actions so `Run` is the filled primary action, `History` and `Activity` are labeled secondary actions, and `Edit` and `Delete` use icon-only controls.
+- Added optimistic running-state rendering so the `Activity` button appears as soon as a workflow run enters the running state in the workspace UI.
+
+### Prompt updates
+
+- Replaced the prompt row's text-heavy action buttons with icon-only `View`, `Edit`, and `Delete` controls.
+- Added a read-only prompt details view that opens in the shared item details modal using a smaller dialog size than the agent or action detail view.
+
+### Agent updates
+
+- Updated the personal workspace agent chat action to use the filled chat icon treatment so it matches the button language used elsewhere in the workspace.
+
+## Usage Instructions
+
+1. Open `Your Workflows` from the workspace sidebar.
+2. Use the list or grid toggle in the workflow toolbar to switch layouts.
+3. Run a workflow with the filled `Run` button, then open `Activity` or `History` from the same action group.
+4. Open `Your Prompts` and use the eye button to preview a prompt without entering edit mode.
+
+## Testing And Validation
+
+- Added `functional_tests/test_workspace_workflow_prompt_ui_refresh.py` to verify the template and JavaScript contract for the refreshed workflows and prompts UI.
+- Added `ui_tests/test_workspace_workflow_prompt_ui_refresh.py` to validate the refreshed workflow toolbar, workflow action buttons, workflow grid view, and prompt details modal in a browser workflow.
+- The browser UI test requires `SIMPLECHAT_UI_BASE_URL` and `SIMPLECHAT_UI_STORAGE_STATE` in an authenticated environment.

+# Azure Maps OpenLayers Inline Maps
+
+Implemented in version: **0.241.046**
+
+## Overview
+
+SimpleChat now includes a built-in Azure Maps action that prepares inline OpenLayers maps directly inside assistant chat messages. Agents can pass structured court, site, or area coordinates into the action, and the chat UI renders the result as an interactive map card with markers, polygon overlays, and standard citation details.
+
+## Dependencies
+
+- `application/single_app/functions_azure_maps.py`
+- `application/single_app/semantic_kernel_plugins/azure_maps_openlayers_plugin.py`
+- `application/single_app/route_frontend_conversations.py`

+- `application/single_app/static/js/chat/chat-messages.js`
+- `application/single_app/static/js/chat/chat-citations.js`
+- `application/single_app/static/css/chats.css`
+- `application/single_app/templates/chats.html`
+
+## Technical Specifications
+
+### Action configuration
+
+- Added a new built-in action type: `azure_maps_openlayers`.
+- The workspace action modal now shows a dedicated Azure Maps configuration card instead of the generic endpoint/auth form.
+- Only an Azure Maps subscription key is required from the user.
+- Runtime defaults force the Azure Maps endpoint to `https://atlas.microsoft.com` and the action auth type to `key`.
+
+### Secure tile delivery
+
+- The browser does not receive the raw Azure Maps subscription key.
+- The backend creates a short-lived encrypted tile proxy token from the stored key.
+- Chat maps request raster tiles through `GET /api/azure-maps/tile`, which validates the token, sanitizes tile parameters, and proxies the request to Azure Maps.
+
+### Chat rendering
+
+- The Semantic Kernel action returns a structured payload with `render_type = azure_maps_openlayers` and a `map_payload` contract.
+- Assistant messages now allocate an inline visualization region ahead of the citation accordion.
+- A dedicated chat renderer hydrates Azure Maps artifacts when needed, then initializes OpenLayers with the proxy tile URL, markers, polygon areas, and fit-to-features view settings.
+- Standard agent citation buttons remain available for the same tool invocation.
+
+## Usage Instructions
+
+1. Open the workspace `Actions` tab and create a new action.
+2. Choose the `Azure Maps (OpenLayers)` action type.
+3. Enter the Azure Maps subscription key and save the action.
+4. Assign the action to an agent and call `create_map_visualization` with marker and optional area coordinates.
+5. Review the assistant response in chat and interact with the rendered map card directly inside the message bubble.
+
+## Testing And Validation
+
+- Added `functional_tests/test_azure_maps_openlayers_plugin.py` to validate secure payload generation, token decoding, view defaults, and missing-feature validation.
+- Added `ui_tests/test_workspace_azure_maps_action_modal.py` to validate the workspace modal flow, summary state, and save payload for the new built-in action.
+- Added `ui_tests/test_chat_inline_azure_maps_rendering.py` to validate inline artifact hydration and map-card rendering inside assistant chat messages.
+- The UI tests require `SIMPLECHAT_UI_BASE_URL` and `SIMPLECHAT_UI_STORAGE_STATE` in an authenticated environment.

+# Source Review Load More and Chat Follow-Up Actions
+
+Implemented in version: **0.241.046**
+
+## Overview
+
+This feature improves source-backed web research and conversational follow-through in Chats.
+
+Source Review can now use the optional rendered-page path to click visible Load More controls on official source archive pages. This helps pages that initially expose only a few cards, such as press-release archives that reveal additional dated releases after interaction.
+
+Assistant responses can also surface visible next-step suggestions as prompt buttons. Selecting a suggestion stages it in the chat input and starts a cancelable send countdown, giving users a quick path to continue without treating the suggestion as an already-executed action.
+
+## Dependencies
+
+* Source Review Load More support depends on admins enabling JavaScript rendering and the app host having Playwright browser support installed.
+* Follow-up prompt actions use the existing Chat frontend JavaScript and send-button behavior.
+
+## Technical Specifications
+
+### Architecture
+
+* `application/single_app/functions_source_review.py` detects Load More controls during static extraction and uses the existing optional Playwright renderer to click matching controls.
+* `application/single_app/static/js/chat/chat-messages.js` extracts visible follow-up suggestions from assistant markdown and renders prompt action buttons after the assistant message text.
+* `application/single_app/static/css/chats.css` styles the action buttons and countdown progress.
+* `application/single_app/templates/admin_settings.html` exposes the rendered Load More click cap near the Source Review JavaScript rendering setting.
+
+### Load More Behavior
+
+When JavaScript rendering is enabled, Source Review can click visible controls matching labels such as Load More, Show More, View More, or More News/Results/Articles/Releases. The renderer stops when:
+
+* The configured click cap is reached.
+* No visible matching control is found.
+* A click does not add new text or links.
+* The requested date range appears to be visible for requests like past three years.
+
+The default cap is 6 clicks, and the hard maximum is 12 clicks. Existing URL policy, redirect validation, timeout, content type, page budget, and SSRF protections still apply.
+
+### Follow-Up Actions
+
+Follow-up prompt buttons are created only from visible assistant text near phrases such as if you want, next step, which format do you want, or would you like me to. Buttons use textContent and event listeners rather than HTML injection. Clicking a button fills the input with a normalized prompt and starts a 5-second countdown on the Send button; clicking Send during the countdown cancels auto-send and leaves the prompt staged.
+
+## Usage Instructions
+
+Admins can enable Source Review JavaScript rendering and set Rendered Load More Clicks in Admin Settings > Search & Extract. Users do not need a separate control for Load More; it runs only when Source Review is enabled and a reviewed source page exposes a matching control.
+
+In Chats, users can click follow-up action buttons under assistant responses when the assistant presents concrete next-step options. The staged prompt can be edited, canceled by clicking Send during countdown, or sent automatically when the countdown completes.
+
+## Testing and Validation
+
+Coverage includes:
+
+* `functional_tests/test_source_review_security.py` for Load More detection and click-cap clamping.
+* `functional_tests/test_chat_follow_up_prompt_actions.py` for follow-up prompt action wiring and safe text handling.
+* `ui_tests/test_admin_source_review_settings.py` for the rendered Load More admin control.
+* `ui_tests/test_chat_follow_up_prompt_actions.py` for the chat follow-up action surface when a UI environment is configured.
+
+## Known Limitations
+
+Load More support is intentionally bounded and does not turn Source Review into a full crawler. Pages that require authentication, custom gestures, captchas, or opaque client APIs may still be incomplete. Follow-up prompt buttons are convenience actions for visible suggestions; they do not execute hidden tools or guarantee the assistant can complete the next request without additional context.

+# Chart Action Inline Rendering
+
+## Overview
+
+Implemented in version: **0.241.047**
+
+The built-in `chart` action adds inline Chart.js visualizations to the chat experience. Agents can now generate interactive charts that render directly inside assistant messages instead of returning detached artifacts or raw JSON.
+
+Dependencies:
+
+- `application/single_app/semantic_kernel_plugins/chart_plugin.py`
+- `application/single_app/static/js/chart.min.js`
+- `application/single_app/static/js/chat/chat-inline-charts.js`
+
+## Technical Specifications
+
+### Architecture Overview
+
+The feature is implemented as a first-class built-in Semantic Kernel action. The backend chart plugin validates chart requests, produces a constrained chart payload, and returns a fenced inline chart block. The chat backend appends those validated blocks to the saved assistant message so streaming completion, persisted history, and message reloads all render the same chart output.
+
+### Supported Chart Types
+
+- Line
+- Bar
+- Pie
+- Doughnut
+- Scatter
+- Area
+- Bubble
+- Radar
+- Stacked bar
+- Stacked line
+
+### Configuration Model
+
+Action-level configuration stores `additionalFields.chart_capabilities` so admins can choose which chart types are enabled by default for an action.
+
+Agent-level configuration stores per-assignment overrides in `other_settings.action_capabilities`, allowing an agent to narrow the enabled chart types for a selected chart action without changing the shared action definition.
+
+### Rendering Flow
+
+1. The `chart` plugin validates and normalizes chart data into a safe Chart.js payload.
+2. The plugin returns `chart_markdown` using a `simplechart` fenced block.
+3. `route_backend_chats.py` appends that fenced block to the final assistant content.
+4. `chat-messages.js` extracts the fenced block before markdown rendering, sanitizes the rest of the message, injects a safe chart placeholder, and hydrates it with Chart.js.
+5. `chat-streaming.js` uses the same renderer during streaming updates and finalization.
+
+## Usage Instructions
+
+### Enable and Configure
+
+Create or edit an action of type `chart` from the actions modal. In the configuration step, enable the chart types that action should expose by default. Assign the action to an agent, then use the agent modal to narrow the chart types for that specific assignment if needed.
+
+### User Workflow
+
+When an agent uses the chart action, the assistant response can contain narrative text plus one or more inline charts. Users can interact with the chart legend, resize with the page layout, and expand a data table for the plotted values.
+
+### Integration Points
+
+- Action creation UI: `templates/_plugin_modal.html`
+- Agent assignment UI: `templates/_agent_modal.html`
+- Chat rendering: `static/js/chat/chat-messages.js`
+- Streaming rendering: `static/js/chat/chat-streaming.js`
+
+## Testing and Validation
+
+Functional coverage:
+
+- `functional_tests/test_chart_action_inline_rendering.py`
+
+UI coverage:
+
+- `ui_tests/test_chat_inline_chart_rendering.py`
+
+Validation focus:
+
+- chart payload normalization and markdown generation
+- per-action chart capability defaults
+- per-agent chart type narrowing
+- inline rendering on both saved messages and streaming updates
+
+Known limitations:
+
+- UI tests require an authenticated chat URL and optional browser storage state supplied through environment variables.

+# Deep Research
+
+Implemented in version: **0.241.051**
+
+## Overview
+
+Deep Research is the user-facing research mode for chat requests that need stronger web evidence. It combines bounded web-search query planning, direct URL inspection, guarded source-page review, link traversal, optional JavaScript rendering, and a persisted research ledger.
+
+Source Review remains the internal source-inspection component. Users see Deep Research in chat; admins still keep safety and budget controls for the underlying page review engine.
+
+## Dependencies
+
+- Web Search / Grounding with Bing Search through the existing Foundry web-search agent for query discovery.
+- Source Review for SSRF-safe page fetching, parsing, prompt-injection isolation, and evidence packets.
+- Generated analysis artifacts for optional Markdown research ledger storage.
+- Optional Playwright runtime support when JavaScript rendering and Load More handling are enabled.
+
+## Technical Specifications
+
+### Architecture
+
+Deep Research runs in the chat backend before the final model response:
+
+1. The current user message is used as the only outbound web-search input boundary.
+2. If Web Search is active, Deep Research plans a bounded set of query variants from the current message only.
+3. Each planned query is sent through the existing Foundry web-search agent within the configured query limit.
+4. Search result URLs and direct user-provided URLs are collected as Source Review seeds.
+5. Source Review validates every URL before fetch, blocks unsafe hosts, applies page/time/size/redirect limits, extracts evidence packets, and records skipped URLs.
+6. A Deep Research ledger summarizes queries, discovered citations, reviewed pages, skipped pages, direct URL caps, Load More behavior, and coverage.
+7. When enabled, the ledger is saved as a Markdown generated analysis artifact in the chat.
+
+### API Behavior
+
+The chat request accepts both fields for compatibility:
+
+- `deep_research_enabled`: user-facing Deep Research toggle.
+- `source_review_enabled`: existing internal compatibility flag.
+
+The response and assistant-message metadata include:
+
+- `source_review`: compact internal review metadata.
+- `deep_research`: user-facing ledger metadata with query plan, web-search runs, coverage, and optional ledger artifact reference.
+
+### Configuration
+
+Admin settings include:
+
+- Enable Deep Research for chat.
+- Activation mode: user toggle only. Web Search by itself does not start Deep Research or Source Review.
+- Max pages per turn.
+- Max seed pages per turn.
+- Max user URLs per turn.
+- Max search queries per turn.
+- Source traversal depth.
+- Timeout, redirect, and page-size limits.
+- Query planning toggle.
+- Ledger artifact toggle.
+- Source link planning toggle.
+- JavaScript rendering and Load More click cap.
+- robots.txt, domain allow/block, and user allow/block controls.
+
+Hard limits remain server-side and cannot be exceeded by admin settings.
+
+## Usage Instructions
+
+In chat, the Deep Research button appears only when:
+
+- Web Search is active, or
+- The prompt contains at least one direct `http://` or `https://` URL.
+
+When selected, the chat request runs Deep Research before the final answer. If direct URLs exceed the configured cap, the first configured number of URLs are reviewed and the omitted count is recorded in the ledger.
+
+## Testing and Validation
+
+Coverage added in this version:
+
+- Functional test for Deep Research config clamping, direct URL caps, query planning, and ledger Markdown generation.
+- Admin UI test updates for Deep Research controls and new budgets.
+- Chat UI test for Deep Research button visibility when Web Search is active or prompt URLs are present.
+
+Validation should include Python compilation, JavaScript syntax checks, focused functional tests, and focused UI tests when a runnable authenticated environment is available.
+
+## Known Limitations
+
+- Web-search query planning is bounded and current-message-only; it does not use conversation history.
+- JavaScript rendering depends on Playwright availability in the app host.
+- Ledger artifact creation is inline with the chat turn so the final answer can use the same reviewed evidence; the artifact uses the existing generated analysis artifact pipeline rather than a separate long-running queue.

+# Deep Research Admin Policy Editor - v0.241.055
+
+Fixed/Implemented in version: **0.241.055**
+
+Superseded in version: **0.241.066** for user policy management. Deep Research now uses allowed users only; blocked-user lists are no longer exposed or enforced. See `docs/explanation/features/v0.241.066/DEEP_RESEARCH_ALLOWED_USERS_MODAL.md`.
+
+Related version update: `application/single_app/config.py` was incremented to `0.241.055` for this enhancement.
+
+## Overview
+
+The Deep Research admin policy controls now use structured editors instead of raw list textareas. Administrators can add, edit, and delete allowed or blocked domains directly, and can manage allowed or blocked users with Microsoft Graph user search plus bulk entry support.
+
+## Dependencies
+
+- Deep Research settings in `application/single_app/functions_settings.py`
+- Admin settings form handling in `application/single_app/route_frontend_admin_settings.py`
+- User search endpoint `GET /api/userSearch`
+- Browser behavior in `application/single_app/static/js/admin/admin_settings.js`
+
+## Technical Specifications
+
+- Hidden form fields preserve the existing setting names:
+  - `source_review_allowed_domains`
+  - `source_review_blocked_domains`
+  - `source_review_allowed_users`
+  - `source_review_blocked_users`
+- Client-side editors serialize policy values as newline-delimited text, keeping compatibility with `parse_source_review_list()`.
+- Domain values are normalized client-side by trimming whitespace, lowercasing, and removing `http://` or `https://` prefixes when admins paste full URLs.
+- User values are added from Graph search results by email when available, falling back to the user ID.
+- Untrusted values are rendered with DOM node creation and `textContent`/form input values instead of dynamic HTML interpolation.
+
+## Usage Instructions
+
+1. Open Admin Settings and navigate to Search & Extract.
+2. Enable Deep Research if needed.
+3. Add allowed or blocked domains with the policy domain input.
+4. Edit existing domain entries inline or remove them with the delete button.
+5. Search for individual users by name or email for allowed/blocked user policies.
+6. Paste multiple emails or user IDs into Bulk Add to add several user policy entries at once.
+
+## Testing and Validation
+
+- Updated `ui_tests/test_admin_source_review_settings.py` to validate the new domain add/edit/delete flow and user bulk controls.
+- Validated that the admin UI continues to submit the same backend field names, so existing settings persistence remains unchanged.
+- Client rendering follows the repository XSS-safe DOM creation pattern for policy values and Graph user search results.
+
+## Known Limitations
+
+- User search depends on the existing Microsoft Graph-backed `/api/userSearch` endpoint and requires the same permissions/configuration as group member search.
+- Bulk user entry accepts explicit emails or user IDs; it does not resolve display names from pasted text.

+# Home Page Logo Scale Control
+
+## Overview
+
+- Version implemented: 0.241.058
+- Dependencies: Admin Settings branding form, landing page template, admin settings JavaScript
+- Purpose: Let admins control the home page logo size independently from the top and sidebar navigation logos.
+
+## Technical Specifications
+
+### Architecture Overview
+
+The feature adds a persisted numeric setting, `landing_page_logo_scale_percent`, to the application settings document. The admin settings page exposes the value through a bounded range slider, and the landing page uses the saved value when rendering the logo on `index.html`.
+
+### Configuration
+
+- Setting name: `landing_page_logo_scale_percent`
+- Default value: `100`
+- Allowed range: `50` to `500`
+- Scope: Home page only
+
+### File Structure
+
+- `application/single_app/functions_settings.py`: default setting value
+- `application/single_app/route_frontend_admin_settings.py`: input parsing and persistence
+- `application/single_app/templates/admin_settings.html`: branding slider control
+- `application/single_app/static/js/admin/admin_settings.js`: live slider value display
+- `application/single_app/templates/index.html`: home page logo render sizing
+- `ui_tests/test_admin_home_page_logo_scale_slider.py`: UI regression coverage
+
+## Usage Instructions
+
+1. Open Admin Settings.
+2. Go to the General tab and find the Branding card.
+3. Move the Main Page Logo Size slider between `50%` and `500%`.
+4. Save the settings.
+5. Open the home page to verify the updated logo size.
+
+The slider only affects the large logo rendered on the home page. It does not resize the logo in `_top_nav.html`, `_sidebar_nav.html`, or `_sidebar_short_nav.html`.
+
+## Testing And Validation
+
+- UI regression coverage: `ui_tests/test_admin_home_page_logo_scale_slider.py`
+- Input validation: admin settings parsing clamps out-of-range or invalid values back into the supported `50` to `500` range.
+- Rendering validation: the landing page reads the saved percentage and applies it only to the home page logo height.
+
+## Limitations
+
+- The UI regression test verifies the slider behavior without saving shared admin settings in a live environment.
+- Navigation logos intentionally keep their existing fixed sizes.

+This enhancement upgrades the existing `blob_storage` action type from a hidden, mostly listing-oriented plugin into a container-scoped Blob Storage action that is usable from the workspace action modal. The action now supports capability defaults for listing container contents, reading file content, and uploading files, with Markdown as the first supported file type for read and upload operations.
+
+## Dependencies
+
+- `application/single_app/functions_blob_storage_operations.py`
+- `application/single_app/semantic_kernel_plugins/blob_storage_plugin.py`
+- `application/single_app/semantic_kernel_loader.py`
+- `application/single_app/route_backend_plugins.py`
+- `application/single_app/json_schema_validation.py`
+- `application/single_app/semantic_kernel_plugins/plugin_health_checker.py`
+- `application/single_app/static/js/plugin_modal_stepper.js`
+- `application/single_app/templates/_plugin_modal.html`
+
+## Technical Specifications
+
+Architecture overview:
+- The action remains `blob_storage`, but it is now configured as a single-container action instead of a broad account-level listing tool.
+- Saved defaults live in `additionalFields` using three maps:
+  - `blob_storage_capabilities`
+  - `blob_storage_read_file_types`
+  - `blob_storage_upload_file_types`
+- The runtime plugin derives the Blob endpoint from the stored connection string when possible so the shared validation and loader flows continue to work with the existing manifest format.
+
+Capability model:
+- `list_container_contents`
+- `read_file_content`
+- `upload_file_to_container`
+
+Configuration model:
+- Required connection string
+- Required container name
+- Optional blob prefix
+- Markdown-only read/upload file type toggles in this first version
+
+Runtime behavior:
+- The plugin exposes only the enabled functions in metadata and loader overlays.
+- Listing returns blob names, relative paths, file types, and whether each blob is supported for read or upload.
+- Read operations are limited to supported UTF-8 text files and currently expect Markdown extensions.
+- Upload operations are limited to supported file types and currently write Markdown with a text/markdown content type.
+
+## Usage Instructions
+
+1. Create a new workspace action and choose `Blob Storage`.
+2. Enter an Azure Storage connection string with access to the target container.
+3. Set the container name and, if needed, a blob prefix such as `docs/markdown`.
+4. Enable the default capabilities the action should expose.
+5. Leave Markdown enabled for any read or upload capability you turn on.
+6. Save the action and assign it to agents as needed.
+
+## Testing And Validation
+
+Functional coverage:
+- `functional_tests/test_blob_storage_action_capabilities.py`
+
+UI coverage:
+- `ui_tests/test_workspace_blob_storage_action_modal.py`
+
+Validation focus:
+- connection-string endpoint derivation
+- capability-gated plugin metadata
+- modal visibility and validation rules for Blob Storage
+- workspace save payload shape for container name, prefix, and file-type defaults

+# Source Review Archive Reliability - v0.241.062
+
+Fixed/Implemented in version: **0.241.062**
+
+Related version update: `application/single_app/config.py` was incremented to `0.241.062` for this enhancement.
+
+## Overview
+
+Source Review now preserves structured archive and listing rows from generic page markup, improving reliability for official news, press-release, investor-relations, RSS, Atom, sitemap, and search-result pages that expose many dated cards behind repeated Load More interactions.
+
+Source Review remains the internal bounded source-inspection layer used by Deep Research. This enhancement does not add site-specific scraping rules or unbounded crawling.
+
+## Dependencies
+
+- `aiohttp` for bounded HTTP retrieval.
+- `beautifulsoup4` for HTML/XML parsing.
+- Optional Playwright browser support when admins enable JavaScript rendering.
+
+## Technical Specifications
+
+### Architecture
+
+- HTML extraction now emits `structured_items` for repeated archive/list/result patterns.
+- Each structured item preserves a title, URL, nearby text, same-domain signal, and normalized published date when available.
+- XML feed extraction emits the same structured item shape for RSS, Atom, and sitemap entries.
+- Deep Source Review can use structured items as bounded child-page candidates, so generic "Learn more" links still retain their surrounding card title and date.
+- Rendered Load More handling first targets controls by accessible role/text, then falls back to a wider bounded scan across interactive controls.
+- Rendered pages now wait for observable content changes after each click before deciding whether pagination stalled.
+
+### Configuration
+
+- Existing Source Review and Deep Research settings continue to apply.
+- Structured items are capped by the hard internal `max_structured_items_per_page` limit.
+- Load More clicks remain capped by `source_review_js_load_more_clicks` and the hard maximum.
+
+### File Structure
+
+- `application/single_app/functions_source_review.py`: extraction, evidence packaging, traversal candidates, rendered Load More behavior, coverage metadata.
+- `functional_tests/test_source_review_security.py`: structured archive-card extraction regression coverage.
+- `functional_tests/test_source_review_deep_traversal.py`: structured item traversal candidate regression coverage.
+
+## Usage Instructions
+
+Admins do not need a new setting. When Source Review is enabled, and JavaScript rendering is enabled for dynamic pages, Deep Research can inspect official listing pages and preserve dated rows from repeated card/list markup more consistently.
+
+## Testing and Validation
+
+- Functional tests validate generic card extraction with non-descriptive "Learn more" links.
+- Functional tests validate that structured archive items can feed bounded child traversal.
+- Existing SSRF, URL validation, page budget, depth budget, redirect, content-size, and prompt-injection isolation controls remain in place.
+
+## Known Limitations
+
+Source Review is still intentionally bounded. It does not bypass authentication, captchas, robots policy settings, domain policy, page budgets, or unsafe URL validation. Pages that require opaque client APIs without visible rendered output may still report partial coverage.

+# Source Review Dynamic Archive Hydration - v0.241.063
+
+Fixed/Implemented in version: **0.241.063**
+
+Related version update: `application/single_app/config.py` was incremented to `0.241.063` for this enhancement.
+
+## Overview
+
+Source Review now waits for rendered archive/list pages to hydrate dated source rows before clicking visible Load More controls. This improves Deep Research coverage for official archives where the Load More button appears before the dynamic card list has finished attaching data and event handlers.
+
+The fix is generic and does not add site-specific scraping rules.
+
+## Technical Specifications
+
+- The rendered fetch path waits for network idle, dated link/list/card evidence, and a short content-stability window before Load More clicks begin.
+- Post-click content-change waits use bounded time derived from the existing Source Review timeout setting.
+- Existing SSRF, domain policy, redirect, content-size, page budget, depth budget, and Load More click caps remain in force.
+- Deep Research ledger coverage continues to report Load More click counts and structured item totals.
+
+## Usage Instructions
+
+Admins do not need to change settings. Existing Source Review JavaScript rendering and Load More settings continue to control whether this path runs and how many Load More interactions are allowed.
+
+For multi-year archives, admins may still need a high enough `source_review_js_load_more_clicks` value to reach the requested date range within the hard cap.
+
+## Testing and Validation
+
+- `functional_tests/test_source_review_security.py` validates that Source Review waits for rendered archive hydration before clicking Load More.
+- Existing Source Review traversal, Deep Research ledger, and web-search citation seeding tests cover the downstream evidence flow.
+
+## Known Limitations
+
+Source Review remains a bounded source-inspection workflow, not a crawler. It will not bypass authentication, captchas, robots policy settings, unsafe URL validation, or configured page and click limits.

+# Deep Research Allowed Users Modal
+
+Version implemented: **0.241.066**
+
+Fixed/Implemented in version: **0.241.066**
+
+## Overview
+
+Deep Research admin access control now uses an allow-only user policy with a compact management modal. The main Search & Extract settings card keeps domain allow/block editors visible, while user management moves behind a **Manage Users** button to keep the page usable as the allowlist grows.
+
+## Dependencies
+
+- `application/single_app/config.py` version `0.241.066`
+- Bootstrap modal components in `application/single_app/templates/admin_settings.html`
+- Admin settings behavior in `application/single_app/static/js/admin/admin_settings.js`
+- User search endpoint: `GET /api/userSearch?query=...`
+
+## Technical Specifications
+
+- Deep Research no longer exposes or enforces blocked-user policy lists.
+- Legacy `source_review_blocked_users` values are ignored by the runtime access check and cleared on admin save.
+- Allowed users are stored in the existing `source_review_allowed_users` setting as newline-delimited email addresses or user IDs.
+- The modal supports manual adds, directory search selection, filtering current allowed users, remove actions, and CSV upload.
+- CSV upload accepts `userId,displayName,email` or `email` headers and adds email addresses first, falling back to user IDs.
+- New Deep Research defaults use the current hard maximum safety budgets and enable the optional research helpers behind the master feature toggle.
+
+## Usage Instructions
+
+1. Open **Admin Settings** > **Search & Extract**.
+2. Enable **Deep Research** when needed.
+3. Use **Allowed Domains** and **Blocked Domains** for domain policy.
+4. Select **Manage Users** to open the allowed-user modal.
+5. Add users by directory search, manual email/user ID, or CSV upload.
+6. Leave the allowed-user list empty to allow all signed-in users.
+
+## Testing and Validation
+
+- `functional_tests/test_source_review_security.py` validates allow-only user access, ignored legacy blocked-user settings, safe max defaults, URL safety, and evidence extraction behavior.
+- `functional_tests/test_deep_research_query_planning_and_ledger.py` validates Deep Research max defaults and query/ledger behavior.
+- `ui_tests/test_admin_source_review_settings.py` validates the compact admin policy UI, absence of blocked-user controls, allowed-user modal behavior, and CSV upload.
+
+## Configuration Notes
+
+The application version was updated in `application/single_app/config.py` to `0.241.066`. Deep Research defaults were updated in `application/single_app/functions_settings.py` and mirrored in `application/single_app/functions_source_review.py`.

+# Deep Research Distroless JavaScript Rendering Runtime
+
+Version implemented: **0.241.067**
+
+Fixed/Implemented in version: **0.241.067**
+
+## Overview
+
+Deep Research JavaScript rendering fallback can now be packaged into the existing SimpleChat Azure Linux distroless application image without changing the final runtime base image. The build installs Playwright and a Chromium browser bundle in the builder stage, copies the browser files and required shared libraries into the final distroless stage, and exposes a runtime capability check in Admin Settings.
+
+## Dependencies
+
+- `application/single_app/config.py` version `0.241.067`
+- `application/single_app/requirements.txt` includes `playwright==1.58.0`
+- `application/single_app/Dockerfile` keeps `mcr.microsoft.com/azurelinux/distroless/python:3.12` as the final stage
+- `application/single_app/functions_source_review.py` provides the cached runtime capability check
+
+## Technical Specifications
+
+- `PLAYWRIGHT_BROWSERS_PATH=/ms-playwright` is set in both builder and final stages.
+- The builder stage installs Azure Linux packages needed by headless Chromium, downloads Playwright Chromium, and preserves the Chromium sandbox binary permissions.
+- The final distroless stage copies `/ms-playwright`, browser shared libraries, and font configuration from the builder stage.
+- Source Review uses shared Chromium launch arguments for runtime probing and rendered fetches.
+- Admin Settings shows whether Playwright Chromium launch was verified in the current runtime.
+- If Playwright is unavailable or Chromium cannot launch, Source Review continues to skip JavaScript rendering gracefully.
+
+## Configuration Options
+
+- `SOURCE_REVIEW_CHROMIUM_NO_SANDBOX=false` by default.
+- Set `SOURCE_REVIEW_CHROMIUM_NO_SANDBOX=true` only after a security review if the hosting platform blocks Chromium sandbox startup.
+- `SOURCE_REVIEW_JS_RENDER_MAX_CONCURRENCY=2` by default. Values are clamped from 1 to 5 to limit simultaneous Chromium rendered fetches per app process.
+
+## Security Considerations
+
+Installing Chromium increases the app image size and the security patch surface. Chromium parses untrusted web content, so vulnerabilities in Chromium, font/media libraries, or browser dependencies become relevant to the app container. The implementation keeps the app running as the existing non-root user and keeps Source Review URL validation, request routing, private network blocking, redirect validation, page budgets, content limits, and timeout controls in place.
+
+Rendered fetches are limited by a small per-process concurrency semaphore to reduce CPU and memory exhaustion risk when multiple users trigger Deep Research at the same time.
+
+The strongest security posture is to keep Chromium sandboxing enabled. Disabling the sandbox may be necessary in some container platforms, but it materially increases risk because compromised browser code would have fewer process isolation boundaries inside the app container. If sandbox disabling is required, restrict Deep Research to trusted admins/users, prefer allowed domains, keep egress controls tight, and patch/rebuild images quickly when Chromium security updates are published.
+
+## Usage Instructions
+
+1. Build and deploy the standard SimpleChat container image.
+2. Open **Admin Settings** > **Search & Extract**.
+3. Check the JavaScript rendering runtime status under **Allow JavaScript rendering fallback**.
+4. Enable JavaScript rendering only when the runtime status confirms Chromium launch support.
+5. Review logs for `js_rendering_dependency_unavailable` or `js_rendering_failed` skipped-source reasons when diagnosing failed rendered fetches.
+
+## Testing and Validation
+
+- `functional_tests/test_source_review_security.py` validates runtime capability reporting.
+- `ui_tests/test_admin_source_review_settings.py` validates that the admin page exposes runtime status.
+- Docker build validation should confirm package availability in the Azure Linux builder stage and Chromium launch verification in the final distroless image.
+
+## Known Limitations
+
+- The runtime probe verifies launch support, not every possible target page behavior.
+- Final distroless image support depends on the copied Azure Linux shared libraries matching Playwright Chromium requirements.
+- Some hosting platforms may block Chromium sandbox startup; use `SOURCE_REVIEW_CHROMIUM_NO_SANDBOX=true` only as an explicit risk acceptance.

+# Assigned Knowledge
+
+Implemented in version: **0.241.068**
+
+Updated in version: **0.241.070**
+
+Updated in version: **0.241.071**
+
+Updated in version: **0.241.087**
+
+Updated in version: **0.241.117**
+
+Updated in version: **0.241.118**
+
+Updated in version: **0.241.119**
+
+## Overview
+
+Assigned Knowledge lets an agent creator bind an agent to a governed set of workspace and web knowledge. When the agent is selected in chat, document search and assigned URL review are forced on from the configured knowledge sources. Agent creators can optionally allow users to add their own workspace documents as task-specific context alongside the assigned baseline.
+
+## Purpose
+
+The feature gives agent owners a predictable retrieval boundary without relying on chat users to manually pick the same documents, tags, or URLs each time. Assigned URLs reuse the existing URL Access and Deep Research policy controls instead of granting broad web browsing on their own.
+
+## Dependencies
+
+- Agent records store configuration in `other_settings.assigned_knowledge`.
+- Chat retrieval uses the existing hybrid search pipeline.
+- Document access is validated against personal, group, and public workspace document stores.
+- The feature uses the current application version from `application/single_app/config.py`.
+
+## Technical Specifications
+
+### Architecture Overview
+
+Assigned Knowledge is stored with the agent and normalized through a shared backend helper before it is saved. During chat, the selected agent is resolved from trusted server-side agent records, then its Assigned Knowledge is applied as the agent baseline. If the agent does not allow user workspace context, browser-provided document scope, selected documents, active group IDs, public workspace IDs, and tag filters are ignored. If the creator allows user workspace context, Assigned Knowledge and user workspace context are searched separately and merged after retrieval. Assigned web sources are passed to Source Review as trusted seed URLs from the stored agent record.
+
+Explicit documents and selected tags are additive at runtime: explicitly selected documents are included alongside documents that match the selected dynamic tag set. Tags remain dynamic criteria and are not expanded into stored document IDs.
+
+User workspace context policy is opt-in and supports separate action permissions for Search, Analyze, and Compare. These permissions are enforced server-side for regular chat, streaming chat, and chat document-action workflows.
+
+Assigned web source modes:
+
+- Review URL reviews the exact assigned URL as URL Access evidence.
+- Deep Research uses the assigned URL as a Source Review seed and can follow bounded child links within the existing Deep Research limits.
+- Both modes still honor admin enablement, role requirements, domain allow/block lists, internal host protections, redirects, robots.txt settings, and page limits.
+
+Scope rules for v1:
+
+- Personal agents can use personal documents and visible public workspaces.
+- Group agents can use only the active group that owns the agent.
+- Global agents can use public workspaces only.
+
+### API Endpoints
+
+- `GET /api/agents/assigned-knowledge/catalog` returns authorized sources, documents, and tags for the agent modal.
+- Existing personal, group, and global agent save endpoints validate and persist `other_settings.assigned_knowledge`.
+- Existing `/api/chat` and `/api/chat/stream` requests enforce assigned knowledge at runtime when the selected agent has it enabled.
+
+### Configuration Options
+
+No new app-level setting is required. Each agent stores:
+
+```json
+{
+  "assigned_knowledge": {
+    "enabled": true,
+    "scopes": {
+      "personal": false,
+      "group_ids": [],
+      "public_workspace_ids": ["public-workspace-id"]
+    },
+    "document_ids": ["document-id"],
+    "tags": ["Finance"],
+    "web_sources": [
+      {
+        "url": "https://example.com/guide",
+        "mode": "deep_research"
+      }
+    ],
+    "allow_user_workspace_context": true,
+    "allowed_user_workspace_actions": ["search", "analyze", "compare"]
+  }
+}
+```
+
+### File Structure
+
+- `application/single_app/functions_assigned_knowledge.py` contains normalization, validation, catalog, and runtime filter helpers.
+- `application/single_app/route_backend_agents.py` exposes the catalog endpoint and validates agent saves.
+- `application/single_app/route_backend_chats.py` enforces runtime search filters and assigned URL source review for regular and streaming chat.
+- `application/single_app/functions_source_review.py` accepts trusted assigned URL seeds while preserving URL Access and Deep Research policy checks.
+- `application/single_app/functions_search.py` and `application/single_app/utils_cache.py` support list-valued public workspace filters and Assigned Knowledge's additive document/tag filter mode.
+- `application/single_app/templates/_agent_modal.html` adds the Knowledge wizard step.
+- `application/single_app/static/js/agent_modal_stepper.js` manages Assigned Knowledge authoring.
+- `application/single_app/static/js/chat/chat-agents.js`, `chat-documents.js`, and `chat-messages.js` apply chat behavior for assigned baseline knowledge and optional user workspace context.
+
+## Usage Instructions
+
+1. Open the agent create or edit modal.
+2. Go to the Knowledge step.
+3. Enable Assigned Knowledge.
+4. Use Source Workspaces to define the document pool, then optionally add Tag Limits or Specific Documents to narrow the final active set.
+5. Add optional Web Sources by pasting one or more URLs and choosing Review URL or Deep Research mode.
+6. Optionally enable User Workspace Context and choose whether users can Search, Analyze, and Compare with their own selected workspace documents.
+7. Save the agent.
+8. Select the agent in chat to force the assigned document and assigned URL context.
+
+The Knowledge step includes an Active Documents preview that shows the final indexed documents the agent will use from the selected source workspaces. With only source workspaces selected, every document in those sources is active. Tag limits narrow the pool to documents that match the selected tag set, and specific documents are included explicitly alongside tag matches. The source workspace picker lists all public workspaces, including public workspaces hidden from the user's normal directory view, so agent creators can find them through search without changing their personal public workspace selector. Web Sources are listed separately because they are live reviewed evidence, not indexed workspace documents.
+
+When users ask an Assigned Knowledge agent what documents, files, sources, or assigned knowledge it can access, chat injects the complete active document inventory so the answer can include the exact active document count and list rather than only the top retrieved citations. Personal agents remain personal conversations even when their Assigned Knowledge comes from public workspaces; the assigned public workspace is tracked as additional locked context so the personal agent remains selectable on later turns.
+
+When Assigned Knowledge is enabled for the selected agent, the chat workspace picker no longer displays the assigned sources as a read-only selection. If User Workspace Context is disabled, the Workspaces button acts as an Assigned Knowledge indicator and user document selections are ignored by the backend. If User Workspace Context is enabled, the Workspaces panel remains available for task-specific user selections while Assigned Knowledge still runs as the agent baseline.
+
+## Testing and Validation
+
+### Test Coverage
+
+- `functional_tests/test_assigned_knowledge_agent_policy.py` validates backend normalization, scope policy, user workspace context policy, assigned web source normalization, Source Review seed URLs, save payload canonicalization, runtime filter conversion, and additive document/tag search semantics.
+- `ui_tests/test_agent_modal_assigned_knowledge_step.py` validates the modal Knowledge step, searchable transfer lists, resolved document preview, web source controls, user context controls, and settings serialization.
+- `ui_tests/test_chat_assigned_knowledge_lock.py` validates chat behavior for assigned-only agents and assigned agents that allow user workspace context.
+
+### Performance Considerations
+
+The catalog endpoint caps returned documents and source IDs to avoid oversized modal payloads. Runtime search uses the existing hybrid search flow and cache keys now include all active public workspace IDs plus the document/tag filter mode to prevent cross-workspace or cross-mode cache reuse.
+
+### Known Limitations
+
+- Assigned web sources are explicit URL seeds only; site-wide or domain-wide crawling is intentionally out of scope.
+- Web search remains a separate chat capability and is not automatically granted by assigned web sources.
+- Group agents are intentionally limited to their owning active group.
+- Global agents cannot use personal or group-scoped knowledge.

+# Deep Research Chromium Build Opt-Out
+
+Version implemented: **0.241.068**
+
+Fixed/Implemented in version: **0.241.068**
+
+## Overview
+
+SimpleChat deployments can now opt out of packaging Playwright Chromium into the application container image. This keeps the existing distroless final image pattern while giving operators a deployment-time choice for environments that do not want a browser runtime in the app container.
+
+## Dependencies
+
+- `application/single_app/config.py` version `0.241.068`
+- `application/single_app/Dockerfile` build argument: `INSTALL_PLAYWRIGHT_CHROMIUM`
+- `deployers/azure.yaml` predeploy ACR build hook
+- `deployers/version.txt` deployer version `1.0.3`
+
+## Technical Specifications
+
+- The Dockerfile defaults `INSTALL_PLAYWRIGHT_CHROMIUM=true`.
+- When true, the builder stage installs Chromium native dependencies, downloads Playwright Chromium, preserves sandbox helper permissions, and copies browser runtime files into the final distroless image.
+- When false, the builder stage skips Chromium native packages and skips the Playwright Chromium browser download. The app still includes the Python Playwright package, but no Chromium browser bundle is packaged into the image.
+- The final distroless image remains `mcr.microsoft.com/azurelinux/distroless/python:3.12` in both modes.
+- Source Review runtime probing continues to report whether JavaScript rendering is actually available after deployment.
+
+## Usage Instructions
+
+To skip Chromium during azd deployment, set the deployment environment value before running `azd up` or `azd deploy`:
+
+```powershell
+azd env set SIMPLECHAT_INSTALL_CHROMIUM false
+azd deploy
+```
+
+For a one-off local shell override:
+
+```powershell
+$env:SIMPLECHAT_INSTALL_CHROMIUM = "false"
+azd deploy
+```
+
+On POSIX shells:
+
+```sh
+SIMPLECHAT_INSTALL_CHROMIUM=false azd deploy
+```
+
+Set the value back to `true` or remove it to return to the default browser-enabled image build.
+
+## Security and Operations Notes
+
+Skipping Chromium is the lowest browser-risk container posture: the app image does not include a browser binary or the extra native rendering dependencies. Deep Research still works through plain HTTP/HTML extraction paths, but JavaScript rendering fallback will show as unavailable in Admin Settings.
+
+Installing Chromium remains useful for JavaScript-heavy source archives. When enabled, keep Chromium sandboxing on, restrict Deep Research users/domains where practical, and monitor CPU and memory because browser rendering is heavier than plain source fetches.
+
+## Testing and Validation
+
+- `functional_tests/test_deep_research_chromium_build_opt_out.py` validates the Dockerfile build argument, azd ACR build wiring, and deployer version bump.
+- `functional_tests/test_source_review_security.py` continues to validate runtime capability reporting and graceful degradation when rendering is unavailable.
+
+## Known Limitations
+
+The deployment hook does not prompt interactively by default because azd deploys often run in CI/CD. Operators should set `SIMPLECHAT_INSTALL_CHROMIUM=false` before deployment when they want to prevent Chromium from being packaged.

+- SimpleChat application setting `enable_source_review`
+- Optional SimpleChat setting `require_member_of_deep_research_user`
+- Entra Enterprise App role value `DeepResearchUser`
+- App role definition in `deployers/azurecli/appRegistrationRoles.json`
+- Deployer version `1.0.4`
+
+## Technical Specifications
+- `functions_source_review.is_source_review_enabled_for_user()` enforces the Deep Research master toggle and, when configured, requires the authenticated session role claim to include `DeepResearchUser`.
+- Chat frontend settings only expose Deep Research to authorized users when the role requirement is enabled.
+- Chat backend routes pass session roles into the authorization helper so client-side toggles cannot bypass the role requirement.
+- Legacy `source_review_allowed_users` and `source_review_blocked_users` settings are normalized to empty lists and are not used for runtime authorization.
+- `config.py` version was updated to `0.241.069`; deployer version was updated to `1.0.4` for the new app role definition.
+
+## Usage Instructions
+1. Enable Deep Research in Admin Settings under Search & Extract.
+2. Leave `Require DeepResearchUser app role` off to allow all signed-in users who can chat to use Deep Research.
+3. Turn on `Require DeepResearchUser app role` to restrict Deep Research.
+4. Assign users or groups to the `DeepResearchUser` role in the Enterprise App before enforcing the requirement.
+
+## Testing and Validation
+- `functional_tests/test_source_review_security.py` validates runtime role gating and the deployment app role definition.
+- `ui_tests/test_admin_source_review_settings.py` validates the Admin Settings app-role toggle and confirms the old assigned-user UI is removed.
+- Deployer regression tests validate the deployer version bump to `1.0.4`.
+
+## Known Limitations
+- Existing signed-in sessions may need to refresh after a role assignment so the updated role claim is present in `session['user']['roles']`.

+# Document Analysis
+
+## Overview
+
+Version: 0.241.023
+
+Fixed/Implemented in version: **0.241.069**
+
+Updated in version: **0.241.023**
+
+Document Analysis adds a deterministic Analyze mode for workflows and chat. Instead of relying on bounded hybrid-search results, the feature targets fixed documents, walks every ordered page or chunk window, and returns a final answer with explicit coverage details.
+
+Dependencies: personal workflows, chat streaming, ordered document retrieval in `functions_search_service.py`, and the shared executor in `functions_document_analysis.py`.
+
+## Technical Specifications
+
+Architecture overview:
+The shared executor resolves structured document targets, builds ordered windows from stored chunks, runs the selected model or agent on every window, retries failed windows when configured, and reduces the window outputs into one final answer.
+
+Workflow support:
+Personal workflows now persist an `analyze` configuration with `document_ids`, `doc_scope`, scope hints for group or public workspaces, and optional windowing controls.
+
+Chat support:
+Chat exposes a dedicated Analyze entry point and routes those requests through `/api/chat/analyze/stream`, which reuses the same backend execution path as workflows.
+
+Coverage output:
+Final responses append a deterministic coverage section with total windows, processed windows, failed windows, retries, and per-document range information.
+
+## Usage Instructions
+
+How to enable/configure:
+In the workspace workflow modal, enable `Document analysis selected documents`, provide fixed document ids or use the current workspace selection, and optionally tune window size, window percent, or retries.
+
+User workflows:
+Manual and scheduled workflows can now analyze the full contents of targeted documents without depending on the top search hits.
+
+Interactive chat:
+Open the workspace selector in chat, choose one or more documents, enable `Analyze`, and send the prompt you want applied across every page or chunk window.
+
+Integration points:
+The shared executor is implemented in `application/single_app/functions_document_analysis.py`, the workflow runner calls it through `functions_workflow_runner.py`, and chat reuses the same path from `route_backend_chats.py`.
+
+## Testing And Validation
+
+Test coverage:
+`functional_tests/test_document_analysis_feature.py` verifies the shared executor, workflow storage and runner wiring, chat endpoints, and the workspace/chat entry points.
+
+Performance considerations:
+Document analysis is intentionally more expensive than bounded search because it processes every window for the targeted documents. It is opt-in and leaves the default chat and workflow behavior unchanged.
+
+Known limitations:
+Chat currently uses the default page-based windowing configuration for the interactive analysis entry point. Workflow configuration exposes the more advanced window controls.

+# Web Search Admin Test Button
+
+Version implemented: **0.241.069**
+
+Fixed/Implemented in version: **0.241.069**
+
+## Overview
+
+Admins can now test Web Search from Admin Settings before relying on it in chat. The test uses the current unsaved Azure AI Foundry agent fields, runs a small Grounding with Bing Search prompt, and returns clear success, warning, or failure feedback in the browser.
+
+## Dependencies
+
+- `application/single_app/config.py` version `0.241.069`
+- Azure AI Foundry project endpoint and agent ID
+- Managed identity or service principal access to the Foundry project. Commercial Foundry uses the renamed `Foundry User` role for minimum project access; Azure Government and custom clouds may still show the equivalent `Azure AI User` role name.
+- Foundry agent with Grounding with Bing Search configured
+
+## Technical Specifications
+
+- The existing `/api/admin/settings/test_connection` admin endpoint now handles `test_type: "web_search"`.
+- The backend normalizes the Foundry settings from the current form payload instead of requiring settings to be saved first.
+- The test validates required endpoint, API version, agent ID, and authentication fields before making an outbound Foundry call.
+- Runtime errors are categorized into configuration, authentication, permission, not found, quota/rate limit, network, tool configuration, or unexpected failures.
+- Browser-facing diagnostics redact secret, password, key, and token values before returning error text.
+- The Admin Settings UI renders feedback with DOM APIs and `textContent` so response text is not treated as HTML.
+
+## Usage Instructions
+
+1. Open Admin Settings and select the Search & Extract tab.
+2. Enable Web Search and accept the Grounding with Bing Search notice.
+3. Enter the Foundry project endpoint, API version, agent ID, and authentication fields.
+4. Select **Test Web Search**.
+5. Review the result panel for response preview, citation count, and recommended next steps.
+
+## Testing and Validation
+
+- `functional_tests/test_web_search_admin_connection_test.py` validates settings normalization, preflight validation, successful fake agent responses, no-citation warnings, permission guidance, and secret redaction.
+- `ui_tests/test_admin_source_review_settings.py` validates that the Admin Settings Web Search test button renders and displays a mocked successful response.
+
+## Known Limitations
+
+The test confirms the configured Foundry agent can respond to a small live-search prompt. It cannot guarantee every future user query will return citations, because the final behavior still depends on the agent instructions, Bing grounding availability, quota, and the searched content.

+# Deep Research Setup Guide Modal
+
+## Overview
+The Admin Settings Deep Research section now includes a Setup Guide modal that explains how to configure Deep Research, assign the optional `DeepResearchUser` Enterprise App role, and tune the source-review controls.
+
+Implemented in version: **0.241.070**
+
+## Dependencies
+- Deep Research settings in `functions_source_review.py`
+- Admin Settings template `admin_settings.html`
+- Modal partial `_deep_research_info.html`
+- Optional Entra Enterprise App role `DeepResearchUser`
+- Web Search via Foundry Agent for search-backed Deep Research flows
+
+## Technical Specifications
+- Adds a Bootstrap `Setup Guide` button to the Deep Research card header in Admin Settings.
+- Adds `_deep_research_info.html` as a static modal include, matching existing setup guide patterns such as Web Search and Key Vault.
+- Documents role setup steps for `DeepResearchUser`, configuration guidance for every Deep Research setting, safety boundaries, and troubleshooting checks.
+- Does not add dynamic JavaScript or render untrusted values in the modal.
+- Updates `config.py` version to `0.241.070`.
+
+## Usage Instructions
+1. Open Admin Settings.
+2. Go to the Search & Extract tab.
+3. In the Deep Research card, select `Setup Guide`.
+4. Review the recommended setup steps, app-role assignment flow, settings reference, safety boundaries, and troubleshooting checklist.
+
+## Testing and Validation
+- `ui_tests/test_admin_source_review_settings.py` validates that the modal opens and contains role setup, settings reference, and browser-runtime guidance.
+- The existing Deep Research UI test continues to validate the primary settings controls and removal of the legacy assigned-user UI.
+
+## Known Limitations
+- The modal provides setup guidance only. App role assignment still occurs in Microsoft Entra ID through the Enterprise App experience or deployment automation.

+# Deep Research Internal Network Hostnames
+
+## Overview
+Deep Research now includes an admin-controlled option to review approved internal network hostnames. By default, hostnames that resolve to private/internal IP addresses remain blocked. Admins can enable `Allow internal network hostnames` when Deep Research should inspect internal sites by DNS name.
+
+Implemented in version: **0.241.071**
+
+## Dependencies
+- Deep Research source validation in `functions_source_review.py`
+- Admin Settings Deep Research controls in `admin_settings.html`
+- Admin Settings save handling in `route_frontend_admin_settings.py`
+- Optional domain allow/block policy editors
+
+## Technical Specifications
+- New setting: `source_review_allow_internal_hosts`
+- Default: `False`
+- When disabled, DNS hostnames resolving to private/internal addresses are denied before fetch.
+- When enabled, DNS hostnames resolving to private/internal addresses are allowed if they also pass domain allow/block rules.
+- Literal IP URL hosts remain blocked, including direct private IP, loopback, and metadata-style link-local targets.
+- Localhost, known metadata hostnames, link-local addresses, multicast, reserved, and unspecified addresses remain blocked.
+- Redirect targets are validated with the same policy before fetch.
+
+## Usage Instructions
+1. Open Admin Settings.
+2. Go to Search & Extract.
+3. Enable Deep Research.
+4. Turn on `Allow internal network hostnames` only for environments where the app host should fetch internal DNS names.
+5. Use `Allowed Domains` to limit internal access to approved domains or suffixes when possible.
+6. Save settings and test with an internal DNS URL, not a literal IP address URL.
+
+## Testing and Validation
+- `functional_tests/test_source_review_security.py` validates default denial, opt-in allowance for internal DNS names, and continued blocking for literal IP URL targets.
+- `ui_tests/test_admin_source_review_settings.py` validates the Admin Settings switch and setup guide text.
+
+## Known Limitations
+- Deep Research validates DNS resolution before fetch, but the HTTP client still resolves the hostname during the request. Use domain allowlists and stable internal DNS records to reduce DNS rebinding risk.
+- The feature does not allow direct IP URL targets. Use DNS names for approved internal sites.

+# Analyze Progress And Limits
+
+## Overview
+
+Version: 0.241.023
+
+Fixed/Implemented in version: **0.241.071**
+
+Updated in version: **0.241.023**
+
+This enhancement adds live analysis progress feedback in chat and formalizes per-surface document limits. Chat now shows an overall progress bar plus per-document progress cards while analysis is running, and the product now caps interactive chat analysis at 3 documents while workflows can analyze up to 10 documents per run.
+
+Dependencies: `functions_document_analysis.py`, `route_backend_chats.py`, `chat-thoughts.js`, `chat-messages.js`, `workspace_workflows.js`, and the existing shared workflow executor.
+
+## Technical Specifications
+
+Architecture overview:
+The shared analysis service now pre-resolves targeted documents, tracks chunk and window completion state, and emits structured progress snapshots through its activity callback. The chat streaming endpoint forwards those progress events through the existing background SSE bridge, and the chat thought renderer converts them into Bootstrap progress cards.
+
+Document limits:
+Interactive chat analysis is limited to 3 selected documents for responsiveness. Personal workflows allow up to 10 documents so users can run larger deterministic analyses asynchronously.
+
+Progress model:
+Progress snapshots report overall and per-document counts for completed windows, chunks, failed windows, retries, and current status text. This keeps users informed during long-running analyses without waiting for the final response.
+
+## Usage Instructions
+
+Interactive chat:
+Select up to 3 documents in chat, enable `Analyze`, and send your prompt. The streaming thought area will update with an overall bar and one row per selected file while the analysis is running.
+
+Workflows:
+Use workflows when you need to analyze more than 3 documents. Workflow configuration continues to allow fixed document targeting and now rejects configurations above 10 documents.
+
+User guidance:
+If a user selects more than 3 documents in chat, the UI and backend both return a message directing them to workflows for larger analysis sets.
+
+## Testing And Validation
+
+Functional coverage:
+`functional_tests/test_document_analysis_progress_and_limits.py` verifies shared progress snapshots, streamed chat progress wiring, and chat/workflow document limit enforcement.
+
+UI coverage:
+`ui_tests/test_chat_document_analysis_thought_progress.py` validates that the streaming thought placeholder renders overall and per-document progress bars from a structured analysis progress event.
+
+Performance considerations:
+Progress updates are lightweight structured thought events and reuse the existing streaming bridge. The chat limit keeps the live experience responsive while workflows absorb larger analysis workloads.

+# Document Actions And Comparison
+
+Version: 0.241.072
+
+Fixed/Implemented in version: **0.241.072**
+
+Dependencies: `functions_document_actions.py`, `functions_document_comparison.py`, `functions_workflow_runner.py`, `route_backend_chats.py`, `static/js/chat/chat-messages.js`, `static/js/workspace/workspace_workflows.js`
+
+## Overview
+
+This feature turns analysis into a generic backend document action model and adds deterministic document comparison on top of the same ordered retrieval path.
+
+Chat and workflows now use the same action shape:
+
+- `none` for standard prompt runs
+- `analyze` for full ordered review across fixed documents
+- `comparison` for one-left-to-many-right comparison runs
+
+## Technical Specifications
+
+The backend now normalizes shared document action payloads in `functions_document_actions.py`, including scope hints, ordered window settings, retries, and target documents.
+
+Comparison is implemented in `functions_document_comparison.py` as a backend action, not as a plugin. The service:
+
+- builds full analysis summaries for the left document and each right-side document
+- compares each right document against the left baseline
+- reduces multiple pairwise comparisons into one final response when needed
+- preserves coverage and progress reporting through the existing thought stream model
+
+Workflow execution and chat execution both dispatch through the shared document action runner in `functions_workflow_runner.py` and `route_backend_chats.py`.
+
+## Usage Instructions
+
+In chat, choose an action from the `Action` selector beside document selection.
+
+- `Search Documents` keeps the normal prompt flow while searching the selected documents for relevant context.
+- `Analyze` reviews every ordered page or chunk from the selected documents.
+- `Compare Documents` treats one selected document as the left baseline and compares every other selected document against it.
+
+In workflows, choose `Action Type` in the workflow modal.
+
+- `Analyze` accepts a fixed list of document ids.
+- `Compare Documents` accepts one left document id and one or more right document ids.
+- Chat currently caps document actions at 3 documents and workflows cap them at 10 documents.
+
+## Testing And Validation
+
+Coverage for this feature includes:
+
+- functional wiring tests for the shared document action model and comparison service
+- updated analysis regression tests for the new shared action routes and selectors
+- a UI workflow modal test that verifies comparison payload submission
+
+Known limitation:
+
+- comparison currently supports one-left-to-many-right only; many-to-many comparison is not part of this version.

+# Global Agent Action Disable Controls
+
+Version: 0.241.076
+
+Fixed/Implemented in version: **0.241.076**
+
+Dependencies: `functions_global_actions.py`, `functions_global_agents.py`, `route_backend_plugins.py`, `route_backend_agents.py`, `static/js/admin/admin_plugins.js`, `static/js/admin/admin_agents.js`, `templates/admin_settings.html`
+
+## Overview
+
+This feature adds a reversible enabled-state for global actions and global agents.
+
+Admins can now disable a global item from Admin Settings without deleting it. Disabled items remain stored for later reuse, but they are excluded from runtime loading and user-facing global selection flows until they are re-enabled.
+
+## Technical Specifications
+
+Global action and global agent container helpers now persist an `is_enabled` flag and default new records to `true`.
+
+Runtime helper reads now filter out disabled records by default while admin-management routes explicitly opt into `include_disabled=True` so the Admin Settings page can still list, edit, re-enable, or delete disabled records.
+
+Two new admin endpoints handle partial enabled-state updates:
+
+- `PATCH /api/admin/plugins/<plugin_name>/enabled`
+- `PATCH /api/admin/agents/<agent_name>/enabled`
+
+When an admin disables the currently selected global agent, the backend now attempts to switch `global_selected_agent` to the first remaining enabled global agent. If none remain, the selected-agent setting is cleared so the system does not continue pointing at a disabled record.
+
+## Usage Instructions
+
+Open Admin Settings and go to the `Agents` tab.
+
+- In `Global Agents`, use the new `Enable` or `Disable` button on each row to control whether the global agent is available at runtime.
+- In `Global Actions`, use the new `Enable` or `Disable` button on each row to control whether the global action is loaded at runtime.
+- Disabled items remain visible to admins with a `Disabled` badge so they can be reviewed and re-enabled later.
+
+Selected-agent dropdowns only include enabled global agents.
+
+## Testing And Validation
+
+Coverage for this feature includes:
+
+- `functional_tests/test_admin_global_item_enabled_state.py` for helper, route, schema, and admin UI wiring checks
+- targeted Python compilation for the modified helper and route modules
+- editor diagnostics for the touched Python, JavaScript, HTML, and schema files
+
+Known limitation:
+
+- disabling all global agents is allowed; in that case the selected global agent is cleared and runtime falls back to kernel-only behavior until an agent is re-enabled or a new one is created.

+# Azure CLI Upgrade Script
+
+Version: 0.241.079
+
+Fixed/Implemented in version: **0.241.079**
+
+Dependencies: `deployers/azurecli/upgrade-simplechat.ps1`, `deployers/azurecli/README.md`, `docs/reference/deploy/azurecli_powershell_deploy.md`, `docs/how-to/upgrade_paths.md`, `functional_tests/test_azurecli_upgrade_script.py`
+
+## Overview
+
+This feature adds a standalone Azure CLI PowerShell upgrade script for SimpleChat container deployments.
+
+The new script provides a code-only rollout path for the Azure CLI deployer. It builds the updated SimpleChat image in Azure Container Registry with ACR Tasks, updates the existing Azure App Service container configuration to that image, and restarts the site so the new container is pulled.
+
+## Technical Specifications
+
+The new `upgrade-simplechat.ps1` script is intentionally narrower than `deploy-simplechat.ps1`.
+
+It does not provision or reconfigure the full Azure dependency stack. Instead, it focuses on the day-two operational path that is closest to `azd deploy` for a container-based App Service deployment.
+
+The script supports two targeting modes:
+
+- explicit target selection with `-ResourceGroupName` and `-WebAppName`
+- derived target names with `-BaseName` and `-Environment`, matching the default `deploy-simplechat.ps1` naming convention of `sc-<base>-<environment>-rg` and `<base>-<environment>-app`
+
+The rollout sequence is:
+
+1. verify Azure CLI authentication and optional subscription selection
+2. verify the target Azure Container Registry and enable the admin user if needed to match the existing Azure CLI deployer model
+3. build the requested image tag in ACR with `az acr build`
+4. update App Service container settings with `az webapp config container set`
+5. verify that the web app container configuration now points to the requested image
+6. restart the web app with `az webapp restart`
+
+## Usage Instructions
+
+Run the script from `deployers/azurecli`.
+
+Example using explicit resource names:
+
+```powershell
+./upgrade-simplechat.ps1 `
+    -AcrName registrysimplechatprod `
+    -ImageName simplechat:2026-04-29_01 `
+    -ResourceGroupName sc-contoso-prod-rg `
+    -WebAppName contoso-prod-app
+```
+
+Example using deployer-style name derivation:
+
+```powershell
+./upgrade-simplechat.ps1 `
+    -AcrName registrysimplechatprod `
+    -ImageName simplechat:2026-04-29_01 `
+    -BaseName contoso `
+    -Environment prod
+```
+
+Optional switches:
+
+- `-SkipAcrBuild` when the image tag is already present in ACR and only the App Service needs to move to it
+- `-Slot <name>` to target a deployment slot instead of production
+
+## Testing And Validation
+
+Coverage for this feature includes:
+
+- `functional_tests/test_azurecli_upgrade_script.py` for script and documentation wiring
+- direct script syntax validation with PowerShell parsing
+- focused functional execution of the new regression test
+
+Known limitation:
+
+- the upgrade script follows the current Azure CLI deployer’s ACR admin-credential model for App Service container pulls; it does not yet switch existing web apps to managed-identity-based ACR pull.

+# URL Access
+
+## Overview
+URL Access is a shared, admin-governed direct URL review capability for chat and personal workflows. It lets users explicitly opt in to reviewing HTTP(S) URLs they paste into a prompt without turning every pasted link into an automatic fetch. The feature reuses Source Review's URL safety checks and evidence formatting while keeping Deep Research as a separate user-facing research mode.
+
+Implemented in version: **0.241.081**
+
+Config version reference: `application/single_app/config.py` version `0.241.082` after the `UrlAccessUser` governance update.
+
+## Dependencies
+- URL safety and evidence extraction in `functions_source_review.py`
+- Admin settings defaults and sanitization in `functions_settings.py`
+- Chat request handling in `route_backend_chats.py`
+- Workflow persistence in `functions_personal_workflows.py`
+- Workflow execution in `functions_workflow_runner.py`
+- Workflow authoring UI in `workspace.html` and `workspace_workflows.js`
+
+## Technical Specifications
+- Admin toggle: `enable_url_access`
+- Chat limit: `url_access_max_chat_urls_per_turn`, hard-capped at 100 URLs per chat turn
+- Workflow limit: `url_access_max_workflow_urls_per_run`, hard-capped at 500 URLs per workflow run
+- Shared domain policy: `url_access_allowed_domains` and `url_access_blocked_domains`
+- Legacy aliases: `source_review_allowed_domains` and `source_review_blocked_domains` remain synchronized for existing Deep Research settings
+- Workflow opt-in field: `url_access_enabled`
+- Optional role gate: `require_member_of_url_access_user` with Entra app role `UrlAccessUser` added in version **0.241.082**
+- Runtime context: workflow runs use `URL_ACCESS_CONTEXT_WORKFLOW`
+
+URL Access uses Source Review in `url_access_only=True` mode. That mode reviews only the direct URLs supplied by the user or workflow prompt, does not run Deep Research traversal or web-search query planning, and injects bounded evidence as untrusted source context for the model or agent invocation.
+
+## Usage Instructions
+1. Open Admin Settings.
+2. Go to Search & Extract.
+3. Enable `URL Access for chat and workflows`.
+4. Set chat and workflow URL limits.
+5. Optionally require the `UrlAccessUser` Enterprise App role.
+6. Optionally configure allowed and blocked domain rules.
+7. In chat, paste HTTP(S) URLs and select the `URLs` button before sending.
+8. In a personal workflow, enable `Allow URL Access for this workflow` before saving the workflow.
+
+## Workflow Behavior
+- The workflow prompt is stored as the user-authored message without injected evidence text.
+- When the saved workflow has `url_access_enabled: true`, the runner validates the prompt URLs against the workflow limit and admin enablement.
+- Scheduled and manual runs share the same server-side validation path.
+- Reviewed URL evidence is added only to the execution context and is recorded in workflow metadata and citations for auditability.
+- If admins later disable URL Access and a saved workflow still requests it with URLs, the run fails with a clear administrator-disabled error.
+
+## Testing and Validation
+- `functional_tests/test_source_review_security.py` validates URL Access defaults, limit clamping, domain aliases, and request validation.
+- `functional_tests/test_deep_research_explicit_toggle.py` validates Deep Research remains explicitly selected and can coexist with URL Access.
+- `functional_tests/test_workflow_url_access_policy.py` validates workflow storage, UI, JavaScript payload, and runner wiring.

+## Known Limitations
+- URL Access does not bypass Source Review safety controls for localhost, literal IP targets, metadata hosts, credentialed URLs, unsafe redirects, unsupported content types, or oversized pages.
+- Domain allow/block rules apply to both chat and workflow URL Access.
+- URL Access is explicit. Plain URL presence in a chat message or workflow prompt does not trigger fetching by itself.

+# Deployer Version Tracking
+
+Version: 0.241.082
+
+Fixed/Implemented in version: **0.241.082**
+
+Dependencies: `deployers/version.txt`, `.github/instructions/update_deployer_version.instructions.md`, `CLAUDE.md`, `functional_tests/test_deployer_version_tracking.py`, `docs/explanation/features/index.md`
+
+## Overview
+
+This feature adds a standalone deployer version marker at `deployers/version.txt`.
+
+The deployer version is intentionally separate from the application version in `application/single_app/config.py`. It is meant for CI/CD logic tracking, deployment workflow compatibility checks, and future automation that needs to detect deployer changes without coupling that logic to app feature releases.
+
+## Technical Specifications
+
+The deployer version marker uses a plain text semantic version string with no prefixes, labels, or extra metadata.
+
+Current value:
+
+```text
+1.0.0
+```
+
+This format keeps the file easy to consume from shell scripts, PowerShell, GitHub Actions, Azure DevOps pipelines, or `azd`-adjacent helper scripts.
+
+The initial tracking model is:
+
+- bump the deployer version when CI/CD logic, deployer scripts, deployer configuration structure, or deployment workflow assumptions change
+- keep the deployer version independent from the app version in `config.py`
+- use the plain file content as the single source of truth for deployment-logic version checks
+
+The repository also includes a targeted instruction file at `.github/instructions/update_deployer_version.instructions.md` so agent-driven edits under `deployers/**` are expected to bump `deployers/version.txt` in the same change.
+
+## Usage Instructions
+
+Example reads from the repository root:
+
+```powershell
+Get-Content .\deployers\version.txt
+```
+
+```bash
+cat deployers/version.txt
+```
+
+CI/CD systems can compare this value against known-compatible deployer logic or stamp it into build metadata independently from the app container version.
+
+## Testing And Validation
+
+Coverage for this feature includes:
+
+- `functional_tests/test_deployer_version_tracking.py` to validate the standalone version file, the current app-version wiring for this feature, and the related documentation references
+- the targeted deployer instruction file and repo guidance that require `deployers/version.txt` bumps when deployer files change
+- direct repository inspection to verify the file lives under `deployers/` and stays separate from the application version source
+
+Known limitation:
+
+- the deployer version file is a tracking artifact only in this change; existing deployment scripts and pipelines are not yet auto-reading it unless they are updated to do so.

+# URL Access App Role Governance
+
+## Overview
+Admins can now require the `UrlAccessUser` Enterprise App role before users can use URL Access. This gives URL fetching its own governance boundary separate from Deep Research while preserving the shared URL safety and domain policy controls.
+
+Implemented in version: **0.241.082**
+
+Config version reference: `application/single_app/config.py` version `0.241.082`.
+
+## Dependencies
+- `functions_source_review.py` for URL Access role checks and request validation
+- `route_backend_chats.py` for chat request enforcement
+- `route_backend_workflows.py` for workflow save/manual-run enforcement
+- `functions_workflow_runner.py` for scheduled workflow enforcement
+- `admin_settings.html` and `route_frontend_admin_settings.py` for admin configuration
+- `deployers/azurecli/appRegistrationRoles.json` for the `UrlAccessUser` app role definition
+
+## Technical Specifications
+- New app role value: `UrlAccessUser`
+- New setting: `require_member_of_url_access_user`
+- Default: `False`
+- When enabled, chat URL Access requests require the signed-in user's token to include `UrlAccessUser`.
+- Workflow authoring requires the role before a workflow can be saved with URL Access enabled.
+- Scheduled workflows use the saved `url_access_authorized` marker created during an authorized workflow save, while still respecting the current global URL Access admin toggle.
+- Deep Research remains governed separately by `DeepResearchUser`.
+
+## Usage Instructions
+1. Update the Entra app registration app roles from `deployers/azurecli/appRegistrationRoles.json`.
+2. Assign the `UrlAccessUser` Enterprise App role to users or groups that should use direct URL fetching.
+3. Open Admin Settings.
+4. Go to Search & Extract.
+5. Enable URL Access.
+6. Enable `Require UrlAccessUser app role`.
+7. Save settings.
+
+## Testing and Validation
+- `functional_tests/test_source_review_security.py` validates the app role definition, role detection, user-aware URL Access enablement, and request validation failure reason.
+- `functional_tests/test_workflow_url_access_policy.py` validates workflow save authorization metadata and runner preauthorization handling.
+- `ui_tests/test_admin_source_review_settings.py` validates the admin toggle.
+
+## Known Limitations
+- Scheduled workflows cannot inspect a live user token. They rely on workflow URL Access authorization captured at save time, plus the current global URL Access admin toggle.
+- If admins enable the role requirement after workflows were saved by users without `UrlAccessUser`, those workflows must be re-saved by an authorized user before scheduled URL Access can continue.

+# Deployer Capacity Defaults
+
+Version implemented: **0.241.085**
+Implemented in version: **0.241.085**
+Updated in version: **0.241.206**
+
+## Overview
+
+SimpleChat deployers now default to production-leaning capacity for core retrieval and data services:
+
+- Azure AI Search: Standard S1 (`standard`) with standard Semantic Ranker.
+- Azure Cosmos DB: provisioned throughput using dedicated autoscale throughput on each SimpleChat container.
+
+These defaults reduce first-deployment surprises where workspace search, semantic retrieval, or document ingestion can fail because a free quota or serverless capacity mode is too constrained for realistic testing.
+
+## Dependencies
+
+- `deployers/bicep/modules/search.bicep`
+- `deployers/bicep/modules/cosmosDb.bicep`
+- `deployers/azurecli/deploy-simplechat.ps1`
+- `deployers/terraform/main.tf`
+- `deployers/version.txt`
+- `application/single_app/config.py` version update to `0.241.085`
+
+## Technical Specifications
+
+The Bicep and one-click ARM templates expose these parameters:
+
+- `searchSkuName`, default `standard`
+- `searchSemanticSearchSku`, default `standard`
+- `cosmosCapacityMode`, default `provisioned`
+- `cosmosDatabaseAutoscaleMaxThroughput`, default `1000`; the parameter name is retained for deployment compatibility, but it now controls per-container autoscale max RU/s.
+
+The Azure CLI deployer uses matching PowerShell variables, and the Terraform deployer uses matching input variables. Provisioned Cosmos deployments create the `SimpleChat` SQL database without a shared database throughput offer, then create the application containers with dedicated autoscale throughput so deployments are not capped by the 25-container shared-throughput database limit.
+
+## Usage Instructions
+
+Use the repository defaults for normal development, demos with document upload, user testing, and production-aligned environments.
+
+For short-lived MVP or evaluation phases, Free Azure AI Search/Semantic Ranker or Cosmos DB serverless can still be selected by explicitly changing the deployer parameters or script variables. These settings should not be treated as the default path because they can hit semantic query, indexing, or request-unit limits.
+
+## Testing and Validation
+
+Functional coverage is provided by `functional_tests/test_deployer_capacity_defaults.py`, which validates the Bicep, generated ARM template, Azure CLI, and Terraform deployer defaults stay aligned with S1 Search and provisioned Cosmos DB.
+
+Known limitation: this change affects new deployments and parameter-driven redeployments. Existing Azure resources may require an intentional migration plan if they were originally created as serverless Cosmos DB, shared-throughput Cosmos databases, or lower-tier Search services.

+# Chat Stream Stop Control
+
+## Overview
+
+The chat stream stop control lets users stop an in-progress AI response from the active assistant message. It applies to standard chat streams, agent streams, document-action stream wrappers, and collaborative conversation streams.
+
+Implemented in version: **0.241.097**
+
+Updated in version: **0.241.098** to use a compact, icon-only circular Stop control aligned with the other chat message action buttons.
+
+## Dependencies
+
+- `application/single_app/route_backend_chats.py` for active stream lifecycle state and cancellation.
+- `application/single_app/route_backend_collaboration.py` for collaboration stream cancellation proxying.
+- `application/single_app/static/js/chat/chat-streaming.js` for the message-local Stop button and stopped-response rendering.
+- `application/single_app/config.py` version updated to `0.241.098` with the Stop control refinement.
+
+## Technical Specifications
+
+Active stream sessions now support a `cancel_requested` state and a terminal `canceled` state. The frontend posts to `/api/chat/stream/cancel/<conversation_id>` for personal streams and `/api/collaboration/conversations/<conversation_id>/stream/cancel` for collaborative streams. The streaming generator checks cancellation at key checkpoints and while reading model or agent chunks.
+
+When cancellation is acknowledged, the stream emits a terminal SSE payload with `done: true`, `cancelled: true`, the partial content, and any persisted assistant message metadata. If partial content exists, the backend saves it as an incomplete assistant message with cancellation metadata.
+
+## Usage Instructions
+
+Users click the circular stop-icon button on the currently streaming assistant message. The button changes to a stopping state while the backend cooperatively stops the response. The chat message then renders any partial response with a visible stopped banner.
+
+## Testing and Validation
+
+- Functional coverage: `functional_tests/test_chat_stream_stop_control.py` validates backend route/session wiring, collaboration proxying, frontend stop-button wiring, and version traceability.
+- UI coverage: `ui_tests/test_chat_stream_stop_button.py` verifies the Stop button posts to the cancel endpoint and renders a stopped partial response from a mocked stream.
+
+Known limitation: blocking pre-processing work can only stop at the next cancellation checkpoint, so some document or research operations may take a short moment before the stopped terminal event appears.

+# Document Version Comparison
+
+Implemented in version: **0.241.097**
+Related version update:
+- `application/single_app/config.py` now reports version `0.241.097`.
+
+## Overview
+
+Document comparison now supports selecting multiple stored revisions from the same document family instead of limiting comparison targets to the current revision of each selected document. This lets users compare `v1` vs `v2`, `v1` vs `v3`, or mix one document's older revisions with other selected documents in both chat and workflow experiences.
+
+Dependencies:
+- `application/single_app/functions_documents.py`
+- `application/single_app/route_backend_documents.py`
+- `application/single_app/route_backend_group_documents.py`
+- `application/single_app/route_backend_public_documents.py`
+- `application/single_app/static/js/chat/chat-documents.js`
+- `application/single_app/static/js/chat/chat-messages.js`
+- `application/single_app/static/js/workspace/workspace_workflows.js`
+- `application/single_app/templates/chats.html`
+- `application/single_app/templates/workspace.html`
+
+## Technical Specifications
+
+Architecture overview:
+- Each stored document revision keeps its own document id while sharing a `revision_family_id` with the rest of the family.
+- New per-scope version endpoints expose all stored revisions for a selected document family in personal, group, and public workspaces.
+- Chat comparison expands selected current documents into version-specific comparison targets and lets the user choose the left-side baseline from the chosen revisions.
+- Workflow comparison uses the same version-target model and saves version-specific ids in the existing comparison payload fields.
+
+API endpoints:
+- `GET /api/documents/<document_id>/versions`
+- `GET /api/group_documents/<document_id>/versions?group_id=<group_id>`
+- `GET /api/public_workspace_documents/<document_id>/versions?workspace_id=<workspace_id>`
+
+Configuration options:
+- Existing document action capability limits continue to apply.
+- Comparison document counts are now based on the selected version targets instead of the number of currently selected document families.
+
+File structure:
+- Version metadata exposure: `application/single_app/functions_documents.py`
+- Personal document versions route: `application/single_app/route_backend_documents.py`
+- Group document versions route: `application/single_app/route_backend_group_documents.py`
+- Public workspace versions route: `application/single_app/route_backend_public_documents.py`
+- Chat comparison UI: `application/single_app/templates/chats.html`
+- Chat comparison behavior: `application/single_app/static/js/chat/chat-documents.js`, `application/single_app/static/js/chat/chat-messages.js`
+- Workflow comparison UI and payload builder: `application/single_app/templates/workspace.html`, `application/single_app/static/js/workspace/workspace_workflows.js`
+
+## Usage Instructions
+
+How to use in chat:
+1. Open chat and enable document search.
+2. Select one or more documents.
+3. Change the action to `Compare`.
+4. Choose the versions you want to compare from `Comparison Versions`.
+5. Pick the left-side baseline version.
+6. Send the compare request.
+
+How to use in workflows:
+1. Open `Personal Workspace` and go to `Your Workflows`.
+2. Create or edit a workflow.
+3. Change the action type to `Compare`.
+4. Select workspace documents and choose `Use selected workspace documents`.
+5. Pick the comparison versions and choose the left-side baseline version.
+6. Save the workflow.
+
+Integration points:
+- Chat requests continue to submit `left_document_id` and `right_document_ids`, but those ids can now be multiple revisions from one document family.
+- Workflow saves use the same payload shape, so no backend workflow contract change is required.
+
+## Testing And Validation
+
+Functional coverage:
+- `functional_tests/test_document_actions_and_comparison_feature.py` verifies the new version endpoints, version-aware chat and workflow selectors, and the linked feature documentation.
+
+UI coverage:
+- `ui_tests/test_chat_document_action_selector_labels.py` validates the chat comparison version selector and left-side version picker.
+- `ui_tests/test_workflow_document_action_modal.py` validates workflow version selection and saved comparison payloads.
+
+Performance and limitations:
+- Version selectors currently load on demand per selected document family.
+- Workflow version selection is driven from the currently selected personal workspace documents.
+- Existing administrator document action limits still cap how many comparison targets can run in one request.

+# Chat Comparison Source/Target And Uploads
+
+## Overview
+
+Version: 0.241.103
+
+Implemented in version: **0.241.103**
+
+This enhancement expands chat document comparison so users can stage one Source document and multiple Target documents in a split comparison board. The board now supports both workspace document versions and files uploaded directly into the active chat conversation.
+
+Dependencies:
+
+- Chat comparison UI in `templates/chats.html`
+- Chat comparison state in `static/js/chat/chat-messages.js`
+- Conversation-aware analysis/comparison resolution in `functions_search_service.py`, `functions_document_analysis.py`, and `functions_document_comparison.py`
+
+## Technical Specifications
+
+### Architecture Overview
+
+The chat comparison flow still submits the existing backend contract with `left_document_id` and `right_document_ids`, but the user-facing experience now uses Source and Target terminology.
+
+When a comparison request includes an active `conversation_id`, the document analysis/search layer can now resolve uploaded chat files from conversation messages and load their content for comparison alongside workspace documents.
+
+### File Structure
+
+- `application/single_app/templates/chats.html`
+- `application/single_app/static/js/chat/chat-messages.js`
+- `application/single_app/functions_search_service.py`
+- `application/single_app/functions_document_analysis.py`
+- `application/single_app/functions_document_comparison.py`
+- `application/single_app/route_backend_chats.py`
+
+## Usage Instructions
+
+1. Open the chat compare action.
+2. Select workspace documents to load their available versions.
+3. Drag or assign one item into Source.
+4. Add one or more versions or uploaded chat files into Targets.
+5. Run compare to evaluate the selected Source document against all chosen Targets.
+
+Uploaded files appear automatically when they are part of the active conversation history.
+
+## Testing And Validation
+
+Functional coverage:
+
+- `functional_tests/test_document_actions_and_comparison_feature.py`
+
+UI coverage:
+
+- `ui_tests/test_chat_document_action_selector_labels.py`
+- `ui_tests/test_workflow_document_action_modal.py`
+
+Performance considerations:
+
+- Uploaded chat files are resolved only when a comparison/review request carries an active `conversation_id`.
+- The chat board keeps the existing comparison payload shape to avoid widening downstream workflow contracts.

+# MCP Action Configuration
+
+Implemented in version: **0.241.103**
+
+## Overview
+
+SimpleChat now includes first-class action configuration for Model Context Protocol (MCP) servers. The shared action modal can create MCP action manifests with the fields Semantic Kernel needs for transport, authentication, timeout, tool discovery, and tool exposure setup.
+
+Related config update: `application/single_app/config.py` now sets `VERSION = "0.241.103"`.
+
+## Dependencies
+
+- Semantic Kernel MCP connector support from `semantic-kernel==1.39.4`
+- Shared action modal and action validation pipeline
+- Existing action secret handling through `auth.key` and reusable workspace identities
+
+## Technical Specifications
+
+### Architecture
+
+- Action type: `mcp`
+- Backend defaults and normalization: `application/single_app/functions_mcp_operations.py`
+- Plugin descriptor and factory: `application/single_app/semantic_kernel_plugins/mcp_plugin.py`, `application/single_app/semantic_kernel_plugins/mcp_plugin_factory.py`
+- Discovery endpoint: `POST /api/plugins/mcp/discover`
+- Manifest validation: `application/single_app/semantic_kernel_plugins/plugin_health_checker.py`
+- Shared modal UI: `application/single_app/templates/_plugin_modal.html`
+- Modal controller: `application/single_app/static/js/plugin_modal_stepper.js`
+- Schemas: `application/single_app/static/json/schemas/mcp.definition.json`, `application/single_app/static/json/schemas/mcp_plugin.additional_settings.schema.json`
+
+### Manifest Shape
+
+MCP actions use the normal action document format with MCP-specific `additionalFields`:
+
+```json
+{
+  "type": "mcp",
+  "endpoint": "https://example.com/mcp",
+  "auth": {"type": "key", "key": "..."},
+  "additionalFields": {
+    "transport": "streamable_http",
+    "auth_method": "bearer",
+    "load_tools": true,
+    "load_prompts": false,
+    "request_timeout": 30,
+    "connect_timeout": 10,
+    "sse_read_timeout": 300,
+    "allowed_tool_names": [],
+    "mcp_tools": []
+  }
+}
+```
+
+Supported transports:
+
+- `streamable_http`
+- `sse`
+- `websocket`
+- `stdio`
+
+Supported auth methods:
+
+- `none`
+- `bearer`
+- `api_key`
+- `basic`
+- `identity`
+
+## Usage Instructions
+
+1. Open the workspace action modal.
+2. Select the `MCP` action type.
+3. Choose the transport and provide the endpoint or stdio command.
+4. Choose an authentication method or reusable identity.
+5. Use **Discover Tools** to fetch available MCP tools into cached metadata.
+6. Configure tool loading, optional allowlisted tool names, and cached discovered tool metadata.
+7. Set timeout values between 1 and 300 seconds.
+8. Review the MCP summary and save the action.
+
+## Testing and Validation
+
+Functional coverage:
+
+- `functional_tests/test_mcp_action_manifest_workflow.py`
+
+UI coverage:
+
+- `ui_tests/test_workspace_mcp_action_modal.py`
+
+Validation focus:
+
+- Transport and endpoint requirements
+- Stdio command setup
+- Auth method and credential shape
+- Timeout ranges
+- Tool allowlist and metadata normalization
+- Dynamic tool registration and invocation dispatch
+- Browser discovery flow
+- Shared workspace action save payload
+
+## Known Limitations
+
+- Stdio MCP servers run server-side and should be limited to trusted/admin-managed actions.
+- OAuth and managed-identity token acquisition for arbitrary remote MCP servers is not implemented; bearer/API key/basic auth and reusable identities are supported for the current action flow.

+# Chat Comparison Modal Summary
+
+## Overview
+
+Version: 0.241.104
+
+Implemented in version: **0.241.104**
+
+The chat comparison editor now stays out of the main chat layout until users need it. The inline compare area was reduced to compact Source and Target tags with a single edit button, while the full comparison editor moved into a larger scrollable modal.
+
+Dependencies:
+
+- `application/single_app/templates/chats.html`
+- `application/single_app/static/js/chat/chat-messages.js`
+- existing conversation-aware comparison support from `functions_document_comparison.py` and `functions_search_service.py`
+
+## Technical Specifications
+
+### Architecture Overview
+
+The comparison payload contract is unchanged. Chat still serializes one Source document through `left_document_id` and one or more Target documents through `right_document_ids`, but the visible compare surface is now split into:
+
+- a compact inline summary bar with Source and Target tags
+- a modal editor that contains the full Available Items, Source, and Targets board
+
+This keeps the main chat input area compact while preserving the richer drag-and-drop comparison setup flow.
+
+### File Structure
+
+- `application/single_app/templates/chats.html`
+- `application/single_app/static/js/chat/chat-messages.js`
+- `functional_tests/test_document_actions_and_comparison_feature.py`
+- `ui_tests/test_chat_document_action_selector_labels.py`
+
+## Usage Instructions
+
+1. Choose `Compare` in the chat document action selector.
+2. Review the compact Source and Target tags under the document controls.
+3. Select `Edit Compare` to open the larger comparison modal.
+4. Use the modal to drag items or assign them into Source and Targets.
+5. Close the modal with `Done` and continue chatting with the compact summary preserved inline.
+
+## Testing And Validation
+
+Functional coverage:
+
+- `functional_tests/test_document_actions_and_comparison_feature.py`
+
+UI coverage:
+
+- `ui_tests/test_chat_document_action_selector_labels.py`
+
+Performance considerations:
+
+- The modal reuses the existing comparison selection state instead of reloading a separate compare workflow.
+- The inline summary renders compact labels so long version details do not expand the chat composer area.

+The Databricks action adds Azure Commercial Databricks SQL Warehouse support to the SimpleChat action workflow. It exposes read-only Databricks SQL tools to Semantic Kernel agents through the Databricks Statement Execution API.
+
+## Version Implemented
+
+- Version implemented: **0.241.104**
+- Related version update: [application/single_app/config.py](../../../../application/single_app/config.py)
+
+## Dependencies
+
+- Azure Commercial Databricks workspace
+- Databricks SQL Warehouse ID
+- Databricks token, Azure service principal, managed identity, or reusable workspace identity
+- Semantic Kernel action loading
+
+## Technical Specifications
+
+### Architecture
+
+- `DatabricksPluginFactory` normalizes stored action manifests and creates the Databricks plugin.
+- `DatabricksPlugin` executes SQL through `/api/2.0/sql/statements` and does not require an ODBC driver.
+- `functions_databricks_operations.py` centralizes cloud, auth, and default configuration constants.
+- Runtime loaders use the factory the same way OpenAPI and MCP actions are factory-created.
+
+### Supported Cloud
+
+- `azure_commercial` is the only enabled cloud in this release.
+- Government and other national cloud support should be added as cloud-specific factory branches after API and auth support are validated for each cloud.
+
+### Exposed Functions
+
+- `execute_sql_query`
+- `get_catalogs`
+- `get_schemas`
+- `get_tables`
+- `describe_table`
+
+### Configuration
+
+Action manifests use type `databricks` with these key fields:
+
+- `endpoint`: Databricks workspace URL
+- `auth.type`: `key`, `identity`, or `servicePrincipal`
+- `additionalFields.cloud`: `azure_commercial`
+- `additionalFields.warehouse_id`: Databricks SQL Warehouse ID
+- `additionalFields.catalog`: optional default catalog
+- `additionalFields.schema`: optional default schema
+- `additionalFields.max_rows`: default SELECT/WITH row cap when no LIMIT is supplied
+- `additionalFields.timeout`: HTTP timeout in seconds
+- `additionalFields.wait_timeout`: Statement Execution wait timeout in seconds
+
+## Usage Instructions
+
+1. Open workspace Actions.
+2. Add a new Databricks action.
+3. Enter the Azure Commercial workspace URL and SQL Warehouse ID.
+4. Choose token, service principal, managed identity, or reusable identity authentication.
+5. Assign the action to an agent.
+
+## Testing and Validation
+
+- Functional test: [functional_tests/test_databricks_action_plugin.py](../../../../functional_tests/test_databricks_action_plugin.py)
+- UI test: [ui_tests/test_workspace_databricks_action_modal.py](../../../../ui_tests/test_workspace_databricks_action_modal.py)
+- The plugin validates read-only SQL before issuing HTTP requests.
+- The modal normalizes workspace URLs that accidentally include the Statement Execution API path.
+
+## Known Limitations
+
+- Only Azure Commercial is supported in this release.
+- SQL execution is intentionally read-only by default.
+- Complex quoted Databricks identifiers are not exposed through helper functions; use simple catalog, schema, and table identifiers.

+# Message PowerPoint Export
+
+## Overview
+
+Version: 0.241.105
+
+Implemented in version: **0.241.105**
+
+Chat message actions now include `Export to PowerPoint`, producing a `.pptx` deck from a single message. The exporter keeps the existing markdown-to-export formatting behavior, adds appendix slides for visuals, tables, code blocks, and citations, and attempts to reuse the same model deployment recorded on the source assistant message to reorganize the content into presentation-friendly slides.
+
+Dependencies:
+
+- `application/single_app/route_backend_conversation_export.py`
+- `application/single_app/static/js/chat/chat-message-export.js`
+- `application/single_app/static/js/chat/chat-messages.js`
+- `application/single_app/static/js/chat/chat-tutorial.js`
+- `application/single_app/requirements.txt`
+
+## Technical Specifications
+
+### Architecture Overview
+
+- The backend exposes `POST /api/message/export-powerpoint` alongside the existing Word and email draft export routes.
+- The route loads the requested message, resolves a preferred model deployment from the message metadata when one is available, and asks the existing Azure OpenAI export client path for a slide-outline JSON plan.
+- If model-based slide planning is unavailable, the exporter falls back to deterministic markdown sectioning so the deck is still generated.
+- After the outline slides are built, the renderer appends supporting slides for inline visuals, markdown tables, fenced code blocks, and citations.
+
+### File Structure
+
+- `application/single_app/route_backend_conversation_export.py`
+- `application/single_app/static/js/chat/chat-message-export.js`
+- `application/single_app/static/js/chat/chat-messages.js`
+- `application/single_app/static/js/chat/chat-tutorial.js`
+- `functional_tests/test_per_message_powerpoint_export.py`
+- `functional_tests/test_chat_tutorial_selector_coverage.py`
+
+## Usage Instructions
+
+1. Open the three-dots menu on a chat message.
+2. Select `Export to PowerPoint`.
+3. Wait for the `.pptx` download to complete.
+4. Open the presentation to review the AI-shaped outline slides first, then the appendix slides for visuals, tables, code, and references.
+
+## Testing And Validation
+
+Functional coverage:
+
+- `functional_tests/test_per_message_powerpoint_export.py`
+- `functional_tests/test_chat_tutorial_selector_coverage.py`
+
+Performance considerations:
+
+- Model planning input is capped before the AI call so very long messages do not balloon the outline prompt.
+- Appendix slide counts are capped for visuals, tables, and code blocks to keep exported decks readable.
+
+Known limitations:
+
+- The AI plan is outline-focused, so highly bespoke slide layouts still require manual polishing after export.
+- Supporting content such as tables and code blocks is preserved as appendix material rather than being merged into the main AI-generated storyline.

+# Chat Inline Export Actions
+
+## Overview
+
+Version: 0.241.106
+
+Implemented in version: **0.241.106**
+
+Chat assistant replies can now surface inline export buttons directly inside the message bubble when the latest user prompt explicitly asks for a supported output format. The quick actions reuse the existing per-message export flows, so Word, PowerPoint, Markdown, and email drafts are still only generated when the user clicks the button.
+
+Dependencies:
+
+- `application/single_app/static/js/chat/chat-messages.js`
+- `application/single_app/static/js/chat/chat-message-export.js`
+- `ui_tests/test_chat_inline_export_action_buttons.py`
+
+## Technical Specifications
+
+### Architecture Overview
+
+- The chat renderer inspects the latest user message already present in the chat DOM when a new assistant message is appended.
+- Inline action buttons are shown only for fresh assistant replies and only when the prompt contains a supported export intent such as presentation, Word, Markdown, or email.
+- Generic `presentation` requests surface both Word and PowerPoint shortcuts, while explicit Markdown and email requests show their matching buttons.
+- Button clicks reuse the existing shared per-message export handlers instead of adding a second export implementation path.
+
+### File Structure
+
+- `application/single_app/static/js/chat/chat-messages.js`
+- `application/single_app/static/js/chat/chat-message-export.js`
+- `ui_tests/test_chat_inline_export_action_buttons.py`
+
+## Usage Instructions
+
+1. Ask the assistant to create a supported artifact such as a presentation, Word document, Markdown document, or email.
+2. Wait for the assistant reply to appear.
+3. Click the inline action inside that reply to trigger the existing export or email workflow.
+
+## Testing And Validation
+
+Test coverage:
+
+- `ui_tests/test_chat_inline_export_action_buttons.py`
+
+Known limitations:
+
+- The quick actions rely on keyword intent detection from the latest visible user message, so very indirect phrasing may continue to fall back to the existing three-dots menu.
+- Inline buttons are intentionally limited to new assistant replies so older messages do not change retroactively when the page reloads.

+# Chat Inline Export Action Progress Labels
+
+## Overview
+
+Version: 0.241.107
+
+Implemented in version: **0.241.107**
+
+Inline chat export actions now update their button text while the requested action is in progress. Create-style actions switch to a matching `Creating ...` label until the download is ready, and the email shortcut switches to `Opening Email Draft...` so the UI reflects that it opens a draft instead of silently sending mail.
+
+Dependencies:
+
+- `application/single_app/static/js/chat/chat-messages.js`
+- `application/single_app/static/js/chat/chat-message-export.js`
+- `ui_tests/test_chat_inline_export_action_buttons.py`
+
+## Technical Specifications
+
+### Architecture Overview
+
+- The shared message export listener now applies a pending state only to the inline assistant export buttons.
+- Pending buttons are temporarily disabled, show a spinner, and restore their original label when the existing export or email handler completes.
+- The behavior reuses the existing export/email implementation instead of duplicating download or mail-draft logic.
+
+### File Structure
+
+- `application/single_app/static/js/chat/chat-messages.js`
+- `ui_tests/test_chat_inline_export_action_buttons.py`
+
+## Usage Instructions
+
+1. Ask the assistant to create a supported export such as a PowerPoint, Word document, Markdown document, or email.
+2. Click the inline action inside the new assistant reply.
+3. Watch the button update to a matching in-progress label until the download or email-draft handoff begins.
+
+## Testing And Validation
+
+UI coverage:
+
+- `ui_tests/test_chat_inline_export_action_buttons.py`
+
+Known limitations:
+
+- Progress labels are intentionally limited to the inline assistant buttons and do not alter the three-dots dropdown labels.

+# Chat Clipboard Paste Uploads
+
+## Overview
+
+Version: 0.241.110
+
+Implemented in version: **0.241.110**
+
+The chat composer now accepts clipboard images and browser-exposed clipboard files directly from the main message input. When a user focuses the chat textbox and pastes supported file content, the client routes the pasted `File` objects through the same upload path used by the existing file picker, including conversation auto-creation and upload consent checks.
+
+Dependencies:
+
+- `application/single_app/static/js/chat/chat-input-actions.js`
+- `functional_tests/test_chat_clipboard_paste_upload_support.py`
+- `ui_tests/test_chat_clipboard_paste_upload_workflow.py`
+
+## Technical Specifications
+
+### Architecture Overview
+
+- The chat upload flow now uses a shared `beginChatFileUpload(...)` helper so selected files and pasted files follow the same conversation-creation, consent, and upload sequence.
+- Clipboard file extraction reads `clipboardData.items` first and falls back to `clipboardData.files` so pasted images from common browser flows are captured without affecting normal text paste behavior.
+- Clipboard files with empty names are normalized into a generated filename derived from MIME type before the upload request is sent, which preserves backend extension-based processing for pasted screenshots and nameless blobs.

+- `functional_tests/test_chat_clipboard_paste_upload_support.py`

+
+## Usage Instructions
+
+1. Open Chats and place the cursor inside the main message textarea.
+2. Copy an image or browser-exposed file to the clipboard.
+3. Press `Ctrl+V` inside the message input.
+4. The pasted file uploads into the current conversation, or into a newly created conversation if none exists yet.

+
+UI coverage:
+
+- `ui_tests/test_chat_clipboard_paste_upload_workflow.py`

+# Group File Share Approval Notifications
+
+## Overview
+
+Version: 0.241.111
+
+Implemented in version: **0.241.111**
+
+Group document sharing now follows the same review model as personal document sharing. Documents shared to another group are visible to the receiving group as pending, but they are not available to group document search until a group Owner, Admin, or Document Manager approves the share. Share recipients and share originators now receive notifications for pending, approved, and denied share decisions.
+
+Dependencies:
+
+- `application/single_app/route_backend_group_documents.py`
+- `application/single_app/route_backend_documents.py`
+- `application/single_app/functions_notifications.py`
+- `application/single_app/templates/group_workspaces.html`
+- `functional_tests/test_group_file_share_approval_notifications.py`
+- `ui_tests/test_group_workspace_shared_document_approval.py`
+
+## Technical Specifications
+
+### Architecture Overview
+
+- Group shares are stored as status-qualified `shared_group_ids` entries such as `group-id,not_approved` and `group-id,approved`.
+- Pending group shares are listed for the receiving group but do not satisfy the Azure AI Search access filter until approval changes the entry to `approved`.
+- Pending-share notifications are sent to the receiving group's Owner, Admins, and Document Managers as personal notifications so regular group members are not asked to review shares they cannot approve.
+- Approval and denial notifications are sent to the user who initiated the group share, with fallback to the source group owner when legacy share metadata is unavailable.
+- Receiving groups can approve, deny, or remove a shared document, but cannot view the source group's shared-recipient list or delete the original document.
+
+### API Endpoints
+
+- `POST /api/group_documents/<document_id>/share-with-group` creates a pending group share and notifies receiving group reviewers.
+- `POST /api/group_documents/<document_id>/approve-share-with-group` approves a pending group share and notifies the share initiator.
+- `DELETE /api/group_documents/<document_id>/remove-self` removes the active group from a shared document, treating pending removal as a denial.
+- `GET /api/group_documents/<document_id>/shared-groups` is restricted to managers in the owning group.

+- `application/single_app/functions_documents.py`
+- `application/single_app/functions_notifications.py`
+- `application/single_app/templates/group_workspaces.html`
+
+## Usage Instructions
+
+1. In the owning group workspace, an Owner, Admin, or Document Manager opens the document Share action and selects a target group.
+2. Owners, Admins, and Document Managers in the receiving group receive a notification and see the document as pending in group documents.
+3. A receiving group reviewer approves or denies the share.
+4. Approved documents become available to group document search; denied documents are removed from the receiving group view.

+# Stats Time Windows and Exports
+
+Implemented in version: **0.241.111**
+
+## Overview
+
+Personal profile stats, group stats, and public workspace stats now support the same 7-day, 30-day, 90-day, and custom date-window pattern used by Control Center activity trends.
+
+## Dependencies
+
+- `application/single_app/functions_stats_windows.py` for shared date-window parsing and daily bucket generation.
+- Existing activity log records in the `activity_logs` container.
+- Existing Chart.js rendering on profile, group, and public workspace stats pages.
+
+## Technical Specifications
+
+- Personal stats use `/api/user/activity-trends` with `days`, `start_date`, and `end_date` query parameters.
+- Group stats use `/api/groups/<group_id>/stats` with the same date-window parameters.
+- Public workspace stats use `/api/public_workspaces/<ws_id>/stats` with the same date-window parameters.
+- Each stats API returns a `window` payload and `dateRange` values so the frontend can label charts accurately.
+
+## Usage
+
+Users can select 7 Days, 30 Days, 90 Days, or Custom in the stats tab. Export buttons on personal, group, and public stats pages create CSV files for the selected metric sections and selected date window.
+
+## Testing and Validation
+
+- `functional_tests/test_stats_time_windows.py` validates shared window parsing, custom range handling, and timestamp bucket normalization.
+- `ui_tests/test_stats_time_windows_and_exports.py` validates the browser controls and export modals when authenticated UI test environment variables are available.
+
+## Version Reference
+
+- `application/single_app/config.py` was updated to `0.241.111` for this feature.

+# Profile And Admin Review Tabs
+
+Documentation Version: 0.241.119
+Version Implemented: 0.241.115
+Related Config Update: `application/single_app/config.py` -> `VERSION = "0.241.119"`
+
+## Overview
+This feature consolidates user feedback and safety history into the profile experience while upgrading the admin review pages to a control-center-style layout with tabs, summary stats, filtered data tables, and CSV export actions.
+
+## Purpose
+The goal is to reduce page fragmentation for end users and give admins a denser, easier-to-scan moderation surface. Users now stay inside the profile page for stats, settings, feedback, and violations. Admins keep dedicated feedback and safety pages, but those pages now lead with summary metrics and a separate all-data view.
+
+## Dependencies
+- Frontend: Bootstrap 5 tabs, existing profile hero layout, dedicated page scripts
+- Backend: Flask route modules for profile, feedback, and safety flows
+- Data Sources: feedback Cosmos container and safety Cosmos container
+- Export Format: CSV download responses from feedback and safety backend routes
+
+## Technical Specifications
+
+### Architecture Overview
+The implementation follows the existing page-shell pattern used by other management screens:
+1. The profile page keeps its hero section and introduces four tabs: Stats, Settings, Feedback, and Violations.
+2. Legacy user routes for My Feedback and My Safety Violations now redirect into the profile page with `tab=` deep links.
+3. Profile feedback and profile violations use dedicated JavaScript to lazy-load stats, tables, modals, pagination, and export actions.
+4. Admin feedback and admin safety pages use separate dedicated scripts and a two-tab shell: Stats and All Data.
+5. Backend feedback and safety routes expose matching stats and export endpoints so both user and admin pages share the same server-side aggregation logic.
+
+### API Endpoints
+- `GET /feedback/my/stats`
+- `GET /feedback/my/export`
+- `GET /feedback/review/stats`
+- `GET /feedback/review/export`
+- `GET /api/safety/logs/my/stats`
+- `GET /api/safety/logs/my/export`
+- `GET /api/safety/logs/stats`
+- `GET /api/safety/logs/export`
+
+### File Structure
+Modified frontend and route files:
+- `application/single_app/route_frontend_profile.py`

+- `application/single_app/static/js/admin/admin-safety-violations.js`
+- `application/single_app/route_backend_feedback.py`
+- `application/single_app/route_backend_safety.py`
+
+## Usage Instructions
+
+### User Workflow
+1. Open `/profile` to land on the Stats tab by default.
+2. Switch to Settings for existing profile preferences and profile-specific controls.
+3. Switch to Feedback to review your submitted feedback, filter the table, inspect details, and export matching rows.
+4. Switch to Violations to review your content safety history, inspect moderation details, and export matching rows.
+5. Existing navigation items for My Feedback and My Safety Violations continue to work through redirects and deep links.
+
+### Admin Workflow
+1. Open the admin feedback review page to see aggregate stats first.
+2. Use the All Data tab for filters, editing, retesting, pagination, and export.
+3. Open the admin safety review page to see moderation status and action distributions.
+4. Use the All Data tab to filter, edit notes and actions, and export the current result set.
+
+## Testing and Validation
+- Added functional regression coverage in `functional_tests/test_profile_and_admin_review_tabs.py`.
+- Verified the new JavaScript files with `node --check`.
+- Checked touched routes, templates, and scripts with workspace diagnostics.
+- Confirmed admin save flows use inline modal status text instead of browser `alert()` fallbacks.
+- Fixed the profile tab loader race in 0.241.118 by initializing `window.profilePageConfig` before `profile-tabs.js` loads.
+- Fixed feedback type normalization in 0.241.119 so lowercase stored `positive` and `negative` values count, filter, and render consistently in profile and admin feedback views.
+
+## Known Notes
+- The user profile keeps the existing hero section at the top to match the requested layout.
+- The admin pages intentionally do not reuse the profile hero and instead align more closely with the control center style.

+# Tabular Generated Output Exports
+
+Implemented in version: **0.241.120**
+
+## Overview and Purpose
+
+Large tabular requests can now produce reusable generated exports when the user asks for a row-by-row JSON array, CSV, or similarly large structured result.
+
+Instead of forcing the final assistant reply to inline a large dataset, SimpleChat now saves the generated output into the user's personal workspace and shows a compact preview card in the chat response.
+
+Related config update:
+- `application/single_app/config.py` now reports version `0.241.120`.
+
+Dependencies:
+- `application/single_app/route_backend_chats.py`
+- `application/single_app/functions_simplechat_operations.py`
+- `application/single_app/route_enhanced_citations.py`
+- `application/single_app/static/js/chat/chat-messages.js`
+
+## Technical Specifications
+
+Architecture overview:
+- Tabular chat orchestration now detects requests that are better served as generated JSON or CSV exports.
+- The backend batches large structured-output generation, serializes the result, and uploads the generated file into the current user's personal workspace.
+- Assistant message metadata now persists `generated_tabular_outputs` so the UI can render the export immediately after the message arrives or when chat history reloads.
+- A general authenticated workspace download route reuses the existing authorized blob-serving helper to stream the saved export back to the browser.
+
+Chat behavior:
+- The assistant keeps the conversational reply concise instead of inlining a very large JSON array or CSV body.
+- The assistant can still reference the generated export in its response because the backend appends a system instruction describing the saved file.
+- The UI shows file name, source workbook context, row count, a small preview, and a download button.
+
+Storage model:
+- Generated exports are stored as normal personal workspace documents.
+- JSON and CSV outputs are reusable in future chats because they enter the same document pipeline as other workspace uploads.
+
+## Usage Instructions
+
+How it works:
+1. Ask a tabular question that requests a large structured result, such as one JSON object per row or a CSV export.
+2. Wait for the tabular processing step to finish.
+3. Read the normal assistant summary in chat.
+4. Use the generated export card to preview the saved output and download the full file.
+5. Reuse the saved file later from the personal workspace like any other uploaded document.
+
+Typical requests:
+- "Return one JSON array containing one object per comment row."
+- "Create a CSV of every matching row."
+- "Save the full structured output and give me a summary here."
+
+## Testing and Validation
+
+Functional coverage:
+- `functional_tests/test_tabular_generated_output_exports.py`
+
+UI coverage:
+- `ui_tests/test_chat_generated_tabular_output_card.py`
+
+Validation focus:
+- generated output metadata is persisted on assistant messages
+- non-streaming responses expose metadata for immediate browser rendering
+- the workspace download route serves authorized generated files
+- the chat UI renders preview data without unsafe HTML interpolation
+
+## Known Limitations
+
+- The inline preview is intentionally small and only shows a subset of the generated rows.
+- Very wide JSON objects are truncated in the preview card so the chat layout stays readable.
+- The saved export currently targets the personal workspace even when the source tabular file came from another allowed workspace context.

+# Tabular Chat-Scoped Exports
+
+Overview
+
+Version implemented: 0.241.121
+Dependencies: application/single_app/route_backend_chats.py, application/single_app/functions_simplechat_operations.py, application/single_app/route_enhanced_citations.py, application/single_app/route_backend_conversations.py, application/single_app/functions_retention_policy.py, application/single_app/static/js/chat/chat-messages.js
+
+This update moves generated tabular JSON and CSV exports from the personal workspace pipeline into the active chat conversation. Large structured outputs now save as conversation-scoped blob-backed artifacts, which keeps the assistant reply concise while still giving the user a direct preview and download path.
+
+Technical Specifications
+
+Architecture overview:
+- Generated tabular exports now use a reusable chat artifact helper in application/single_app/functions_simplechat_operations.py.
+- The helper stores the generated file in the personal-chat blob container and persists a hidden blob-backed file message in the conversation.
+- Assistant replies persist lightweight `generated_tabular_outputs` metadata that points at the hidden chat artifact instead of a workspace document record.
+- The download experience now uses an authorized chat artifact route in application/single_app/route_enhanced_citations.py.
+- Personal conversation deletion and retention cleanup now remove blob-backed chat files when archiving is not enabled.
+
+Configuration and file structure:
+- Version source remains application/single_app/config.py.
+- The chat artifact metadata is rendered by application/single_app/static/js/chat/chat-messages.js.
+- Prompt-history reconstruction in application/single_app/route_backend_chats.py skips hidden generated artifacts so they do not pollute later model context.
+
+Usage Instructions
+
+How it works:
+- When a tabular request explicitly asks for downloadable JSON or CSV output, the tabular pipeline generates the file and stores it in the current chat.
+- The assistant message shows a generated export card with a preview, source file details, and a download button.
+- The user can download the artifact directly from the chat without creating a personal workspace document.
+
+Integration points:
+- The new helper is reusable for tabular analysis, review, comparison, or other future flows that need conversation-scoped generated files.
+- The older workspace download path remains available for previously saved workspace-scoped exports.
+
+Testing and Validation
+
+Test coverage:
+- functional_tests/test_tabular_generated_output_exports.py validates the backend helper wiring, chat download route, and chat UI hooks.
+- ui_tests/test_chat_generated_tabular_output_card.py validates card rendering, safe text handling, and chat artifact downloads.
+
+Performance and lifecycle considerations:
+- Chat-scoped exports avoid pushing large structured payloads through the final assistant response.
+- Blob-backed chat files are now cleaned up when personal conversations are deleted without archiving.
+- When conversation archiving is enabled, blob-backed chat files are retained so archived messages keep their blob references.

+# Generated Analysis Artifact Foundation
+
+Overview
+
+Implemented in version: **0.241.125**
+
+This feature introduces a shared chat-scoped artifact foundation for large generated analysis outputs. Instead of forcing full structured review, comparison, or tabular results inline in the assistant message, the backend can now persist the full result as a hidden chat artifact, render a short inline summary plus preview card, and provide a secure download path from the chat UI.
+
+Dependencies
+
+- Chat artifact upload helper in `application/single_app/functions_simplechat_operations.py`
+- Chat document resolution in `application/single_app/functions_search_service.py`
+- Chat assistant persistence in `application/single_app/route_backend_chats.py`
+- Document-action execution in `application/single_app/functions_workflow_runner.py`
+- Artifact rendering in `application/single_app/static/js/chat/chat-messages.js`
+
+Technical Specifications
+
+Architecture overview
+
+- Hidden chat artifacts continue to use blob-backed `role='file'` messages in the personal chat storage container.
+- Assistant messages now persist a generic `generated_analysis_artifacts` metadata array, with `generated_tabular_outputs` retained as a backward-compatible alias for existing UI and tests.
+- Generated artifact file messages now carry generic metadata, including capability, output format, and storage scope.
+- Chat document resolution now distinguishes generated artifacts from regular chat uploads through `source_subtype='generated_chat_artifact'` while preserving the existing `chat_upload` source type for compatibility.
+
+Implemented phases
+
+- **Phase 1**: Generic artifact foundation
+  - Added `upload_generated_analysis_artifact_for_current_user(...)`
+  - Added backend metadata normalization for generic generated artifacts
+  - Added generic artifact UI hydration and preview rendering
+  - Added configurable size cap support through `max_generated_chat_artifact_size_mb`
+
+- **Phase 2**: Document analysis artifacts
+  - Document analysis now creates a chat artifact from the final analysis output when the result is explicitly requested as an artifact, is already structured JSON, or is large enough to justify a downloadable file.
+  - The assistant reply is shortened to a narrative summary when an analysis artifact is created.
+
+- **Phase 3**: Comparison artifacts
+  - Document comparison now creates a chat artifact from the final comparison output under the same artifact-trigger rules.
+  - Comparison artifacts reuse the same generic metadata and UI card surface.
+
+Current boundary
+
+- **Phase 4** promotion and approval flows are not yet implemented.
+- Artifact promotion into personal or group workspaces still needs approval-aware routing.
+- Multi-user collaboration source-conversation routing for generated artifacts is still pending.
+
+Usage Instructions
+
+User workflow
+
+- Ask for a large tabular export, analysis, or document comparison.
+- When the response is structured or large enough, the assistant stores the full result as a hidden chat artifact.
+- The assistant renders a short summary plus a preview card with a download button.
+- The full artifact downloads through `/api/chat_artifacts/download` after conversation ownership checks.
+
+Artifact metadata
+
+- `capability`: `tabular`, `analyze`, or `comparison`
+- `artifact_message_id`: hidden chat file message id
+- `conversation_id`: owning chat id
+- `storage_scope`: currently `chat`
+- `output_format`: `json` or `md` in the current implementation
+- `summary`, `preview_rows`, `preview_items`, or `preview_lines` for UI rendering
+
+Testing and Validation
+
+Functional coverage
+
+- `functional_tests/test_tabular_generated_output_exports.py`
+- `functional_tests/test_document_analysis_generated_artifacts.py`
+- `functional_tests/test_document_comparison_generated_artifacts.py`
+
+Validation performed
+
+- Python compile checks for the touched backend files
+- JavaScript parse check for `chat-messages.js`
+- Focused functional regressions for tabular, analysis, and comparison artifact plumbing
+
+Known limitations
+
+- Promotion/approval flows are still pending
+- Artifact citations are not yet surfaced as first-class downloadable citation chips
+- Public data sources are supported as inputs to single-user chats, but generated artifacts still persist against the owning chat conversation rather than a separate public workspace artifact model

+# Azure Files File Sync
+
+## Overview
+
+Azure Files File Sync adds an Azure Storage file share source type to the existing File Sync workflow. Workspace managers can sync files from an Azure Files share by using a file service URL, share name, and optional directory path instead of an SMB UNC path.
+
+Implemented in version: **0.241.127**
+
+## Dependencies
+
+- `azure-storage-file-share==12.25.0`
+- Existing workspace identity storage and Key Vault secret handling
+- Existing File Sync Redis readiness, schedule, filter, tag, and delete-policy controls
+
+## Technical Specifications
+
+The connector stores `source_type: "azure_files"` and a connection payload with `account_url`, `share_name`, `directory_path`, and `share_url`. Sync runs list files through the Azure Files SDK, stage downloads into the same temporary-file pipeline as SMB sync, and persist synced document metadata with the Azure Files source type.
+
+Supported reusable workspace identity authentication methods for Azure Files are:
+
+- Managed identity
+- Service principal client secret
+- Azure Storage connection string
+
+SMB sources continue to support username/password and anonymous authentication for UNC paths.
+
+## Usage Instructions
+
+Admins can enable Azure Files in Admin Settings under File Sync source type visibility. Workspace managers then choose Azure Files in the Add Source workflow, enter the file service or share URL, share name, and directory path, and select a compatible reusable identity or source-local Azure Files credential.
+
+The managed identity used by the app needs Azure Files data-plane permissions on the target storage account or file share. For SDK-based sync, grant a Storage File Data role that matches the desired read access. For SMB-mounted Azure Files scenarios, use Azure Files SMB managed identity or Kerberos configuration outside SimpleChat and keep using the SMB connector against the mounted/UNC path.
+
+## Testing and Validation
+
+- Functional coverage: `functional_tests/test_file_sync_azure_files_identity.py`
+- Existing File Sync capability coverage: `functional_tests/test_file_sync_capability.py`
+- UI coverage updated for source type visibility and Azure Files source modal rendering
+
+Known limitation: PIV/smart-card authentication is not implemented inside the web app. PIV and smart-card flows belong at the client or domain/Kerberos layer for SMB access; SimpleChat can consume the resulting SMB path through the existing SMB connector.

+
+## Overview
+
+SimpleChat supports generic Microsoft Foundry workflow agents as selectable chat agents through the `foundry_workflow` agent type. The feature is workflow-name driven and does not hardcode any specific workflow names.
+
+## Dependencies
+
+- Microsoft Foundry project endpoint with RBAC permission to invoke workflow agents
+- Existing SimpleChat Foundry managed identity, service principal, or default credential access
+- Project workflow OpenAI-compatible REST protocol version configured on the agent or endpoint
+
+### Foundry RBAC Role Name Guidance
+
+Microsoft Foundry commercial clouds now display the renamed Foundry RBAC role names. Azure Government and custom cloud deployments may still display the earlier Azure AI role names while the rename rolls out. Use the role name shown in the target portal, or use the role definition ID in automation when possible because the IDs and core permissions are unchanged.
+
+| Commercial Foundry role name | Azure Government and custom cloud name that may still appear | Notes |
+|------------------------------|--------------------------------------------------------------|-------|
+| `Foundry User` | `Azure AI User` | Minimum role for identities that build with or invoke Foundry project capabilities. |
+| `Foundry Project Manager` | `Azure AI Project Manager` | Project management role; can conditionally assign the user role where supported. |
+| `Foundry Account Owner` | `Azure AI Account Owner` | Account/resource administration role; in commercial Foundry, can assign selected dependent roles such as `Foundry User`, supported Container Registry roles, and `Log Analytics Reader`. |
+| `Foundry Owner` | `Azure AI Owner` | Full Foundry administration and build role; in commercial Foundry, can assign selected dependent roles such as `Foundry User`, supported Container Registry roles, and `Log Analytics Reader`. |
+
+## Technical Specifications
+
+### Architecture
+
+- Agent records store workflow configuration in `other_settings.foundry_workflow`.
+- Workflow discovery uses the Foundry project agents API and normalizes returned agents into workflow-capable entries, preserving `workflow_agent_id`, `application_id`, `application_version`, and `agent_reference` when available.
+- Runtime invocation mirrors the Foundry SDK flow for delegated workflow calls: create a Foundry OpenAI conversation, call Responses with `agent_reference`, stream events, and delete the Foundry conversation after the run.
+- Workflow invocation requires Microsoft Entra ID/RBAC access. In commercial Foundry, start with `Foundry User` on the project or resource scope used by the endpoint. In Azure Government and custom clouds, use the equivalent role name shown in the portal, which may still be `Azure AI User`. API keys remain supported for model endpoint inference but are not used for chat-selectable Foundry Workflow agents.
+- The verified OpenAI-compatible workflow REST protocol for the test project uses `v1` paths such as `/openai/v1/responses` and `/openai/v1/conversations`, without an `api-version` query parameter.
+- The UI defaults workflow agents to `v1` and no longer exposes `v2` as a normal REST protocol option. Existing saved `v2` workflow values are normalized to `v1` at runtime.
+- Dated preview versions are sent as `api-version` query parameters on both conversation and response endpoints.
+- Streaming chat keeps the HTTP stream open for workflow action events but buffers workflow text deltas and emits the completed final answer once, avoiding partial outline-only chat bubbles.
+- Foundry `response.failed` streaming events surface `response.error.message` directly, so workflow-internal failures are readable.
+- Existing selected workspace document and chat-upload context continues to flow through the normal chat history and augmentation pipeline.
+- Selected workspace files and recent blob-backed chat uploads are attached to workflow requests when possible as Foundry `input_file` content parts with `data:<mime>;base64,...` file data. This includes image uploads, which were verified against Foundry workflows using the `input_file` shape. The same shared collector and payload shape is used for normal new-Foundry Responses agents.
+
+### Configuration
+
+Required workflow settings:
+
+```json
+{
+  "agent_type": "foundry_workflow",
+  "other_settings": {
+    "foundry_workflow": {
+      "workflow_name": "YourWorkflowName",
+      "workflow_agent_id": "optional-discovered-agent-id",
+      "agent_reference": {
+        "type": "agent_reference",
+        "name": "YourWorkflowName",
+        "id": "optional-discovered-agent-id"
+      },
+      "endpoint": "https://<resource>.services.ai.azure.com/api/projects/<project>",
+      "responses_api_version": "v1",
+      "include_document_context": true,
+      "max_context_chars": 24000,
+      "include_file_inputs": true,
+      "max_file_inputs": 5,
+      "max_file_input_bytes": 8388608
+    }
+  }
+}
+```
+
+Optional settings include `workflow_agent_id`, `agent_reference`, `application_id`, `application_version`, `project_name`, `responses_path`, `conversations_path`, Entra authentication fields, `foundry_scope`, `include_file_inputs`, `max_file_inputs`, `max_file_input_bytes`, and admin `notes`. A saved Foundry connection can be selected to fetch workflow-capable agents and reuse project details, but users can also enter the project endpoint, project name, workflow name, and workflow REST protocol version manually.
+
+### File Structure
+
+- `application/single_app/foundry_agent_runtime.py` - workflow runtime, conversation lifecycle, protocol path routing, stream text buffering/error extraction, and discovery facade
+- `application/single_app/functions_agent_payload.py` - workflow payload validation
+- `application/single_app/semantic_kernel_loader.py` - workflow agent construction
+- `application/single_app/route_backend_chats.py` - selected-agent chat invocation and metadata persistence
+- `application/single_app/route_backend_agents.py` - manual Foundry endpoint preservation for personal and group agents
+- `application/single_app/templates/_agent_modal.html` - workflow configuration controls
+- `application/single_app/static/js/agent_modal_stepper.js` - workflow modal state and serialization
+
+## Usage Instructions
+
+1. Create or edit an agent.
+2. Select **Foundry Workflow** as the agent type.
+3. Optionally select a saved Foundry connection to fetch workflows and reuse credentials.
+4. Enter the Foundry project endpoint, project name, workflow name, and workflow REST protocol version.
+5. Save the agent and select it in chat.
+6. Send normal chat text with optional selected workspace documents or uploaded chat files.
+7. For blob-backed uploads and selected documents, SimpleChat attaches bounded file bytes directly to the Foundry workflow request when the file is available and within the configured size/count limits.
+
+## Testing and Validation
+
+- Functional payload validation: `functional_tests/test_foundry_workflow_agent_payload.py`
+- Modal control coverage: `ui_tests/test_agent_modal_foundry_workflow.py`
+- Live endpoint probe confirmed `POST /openai/v1/conversations`, `POST /openai/v1/responses`, and `DELETE /openai/v1/conversations/{id}` against the Retroburn Foundry project.
+- Live file probe confirmed that Foundry workflows accept image bytes as `input_file` with a data URI in `file_data`; raw Base64 and `input_image` data URI requests returned server errors for the tested workflow.
+
+## Known Limitations
+
+- Workflow discovery currently uses the project agent/application listing facade and can be refined if Foundry exposes a more specific workflow list endpoint.
+- File pass-through is bounded by count and byte-size limits. Files that cannot be resolved from existing authorized document/chat context, cannot be downloaded, or exceed the configured limit are skipped while the text context still flows.
+- `responses_path` and `conversations_path` can override the default project OpenAI paths if a Foundry project uses a different endpoint shape.
+
+## Config Version Reference
+
+This feature originally corresponds to the `VERSION = "0.241.128"` update in `application/single_app/config.py` for file input handoff support. Workflow-capable Foundry agent reference preservation was updated in `VERSION = "0.241.192"`. API-key workflow routing for discovered project agents was superseded by Entra-only workflow invocation in `VERSION = "0.241.196"`.

+# Generated Analysis Artifact Workspace Promotion
+
+Overview
+
+Implemented in version: **0.241.127**
+
+This feature completes the next step of the generated analysis artifact flow by letting users move chat-scoped generated outputs into workspace documents. Personal promotions are added immediately to the requester’s workspace. Group and public promotions create a visible pending document shell, notify the workspace, and only become usable after an approver accepts the request.
+
+Dependencies
+
+- Chat artifact authorization and download routes in `application/single_app/route_enhanced_citations.py`
+- Generated document processing helpers in `application/single_app/functions_simplechat_operations.py`
+- Group workspace document routes in `application/single_app/route_backend_group_documents.py`
+- Public workspace document routes in `application/single_app/route_backend_public_documents.py`
+- Chat artifact card rendering in `application/single_app/static/js/chat/chat-messages.js`
+- Group and public workspace document UIs in `application/single_app/templates/group_workspaces.html` and `application/single_app/static/js/public/public_workspace.js`
+
+Technical Specifications
+
+Architecture overview
+
+- Chat artifact cards now expose an `Add to Workspace` action for blob-backed generated artifacts.
+- The backend resolves the target workspace from the active conversation or the selected chat scope.
+- Personal promotions download the artifact bytes and queue the normal workspace document processing flow immediately.
+- Group and public promotions create a pending workspace document record with source blob metadata, approval metadata, and notification entries.
+- Group and public approvers can accept the request from the workspace document list, which then queues the existing document processing pipeline against the stored artifact blob.
+
+Promotion flow
+
+- `POST /api/chat_artifacts/promote`
+  - `personal`: uploads directly into the personal workspace.
+  - `group`: creates a pending group document and sends approval notifications.
+  - `public`: creates a pending public document and sends approval notifications.
+- `POST /api/group_documents/<document_id>/approve-generated-artifact`
+  - Queues the stored artifact into the active group workspace document shell.
+- `POST /api/public_documents/<document_id>/approve-generated-artifact`
+  - Queues the stored artifact into the active public workspace document shell.
+
+Pending document behavior
+
+- Pending group/public promoted files are visible in the workspace list immediately.
+- Pending files have no processed blob/chunk output yet, so they are not usable for search/chat until approval queues document processing.
+- Pending promoted files use a unique artifact-suffixed file name to avoid archiving an existing same-name live document before approval is granted.
+
+Notifications
+
+- Workspace-scoped notifications are created with `approval_request_pending` so the workspace sees a reviewable request.
+- The requester also receives an `approval_request_pending_submitter` notification.
+- On approval, the requester receives an `approval_request_approved` notification when processing is queued.
+
+Usage Instructions
+
+User workflow
+
+- Generate a review, comparison, or tabular artifact in chat.
+- Click `Add to Workspace` on the generated artifact card.
+- If the target is personal, the file is added to the personal workspace immediately.
+- If the target is group or public, the file appears in the workspace as pending approval.
+- A group or public workspace approver clicks `Approve` in the workspace document list.
+- After approval, the file begins processing and becomes usable like any other workspace document once processing completes.
+
+Target resolution rules
+
+- If the current conversation is already scoped to a group or public workspace, that workspace is used.
+- Otherwise, the chat scope selection must resolve to exactly one workspace target.
+- Ambiguous multi-scope selections are rejected in the chat UI before the request is sent.
+
+Testing and Validation
+
+Functional coverage
+
+- `functional_tests/test_generated_artifact_workspace_promotion.py`
+- `ui_tests/test_chat_generated_tabular_output_card.py`
+
+Validation performed
+
+- Python diagnostics and `py_compile` on the touched backend files
+- Workspace UI diagnostics for the touched group/public files
+- Focused functional regression for promotion route and approval UI wiring
+
+Known limitations
+
+- Group/public promotion currently supports approval but not a dedicated deny action.
+- Reloaded artifact cards do not yet deduplicate repeated promotion requests for the same artifact automatically.

+# Safety Violation Remediation Approvals
+
+Overview
+
+Implemented in version: **0.241.127**
+
+This feature lets Safety Violation admins send warning notifications, temporary suspensions, and permanent access blocks from the safety review modal while reusing the same approval authority model as Control Center restrictions.
+
+Dependencies
+
+- `application/single_app/route_backend_safety.py`
+- `application/single_app/route_backend_control_center.py`
+- `application/single_app/functions_approvals.py`

+- `application/single_app/static/js/admin/admin-safety-violations.js`
+- `application/single_app/templates/approvals.html`
+
+Technical Specifications
+
+Architecture overview
+
+- Safety remediation actions now use explicit approval request types for warn, suspend, and block operations.
+- Reviewer eligibility follows the existing `require_member_of_control_center_admin` setting so the same app-level approval authority applies to both Control Center restrictions and safety remediation.
+- Safety admins who already have the required reviewer role can submit and approve their own remediation request in one step.
+- Safety admins without the required reviewer role create a pending approval request instead of executing the remediation immediately.
+- Shared execution helpers now send the user-facing notification and, for suspend or block, write the same `settings.access.status` and `settings.access.datetime_to_allow` payload that Control Center access restrictions already enforce.
+
+Safety review modal behavior
+
+- Selecting `Warn user`, `Suspend user`, or `Block user` reveals a notification field for the affected user.
+- Selecting `Suspend user` also reveals a restore date field that maps to `datetime_to_allow`.
+- The safety review table now shows when a remediation action is pending approval or failed during execution.
+- Successful saves show whether the action executed immediately or created a pending approval request.
+
+Shared approvals behavior
+
+- The approvals page now exposes `Warn User`, `Suspend User`, and `Block User` filters and labels.
+- User-targeted safety approvals are described as a generic `Target` instead of assuming a group-only workflow.
+- The reviewer guidance copy now reflects eligibility-based approval rules instead of only self-request denial language.
+
+Usage Instructions
+
+User workflow
+
+- Open a safety violation from the admin review table.
+- Select `Warn user`, `Suspend user`, or `Block user`.
+- Enter the notification that should be delivered to the affected user.
+- For a suspension, set the restore date and time.
+- Save the violation.
+- If the actor has the required reviewer role, the remediation executes immediately.
+- Otherwise, the request appears in the shared approvals page until an eligible reviewer approves it.
+
+Testing and Validation
+
+Functional coverage
+
+- `functional_tests/test_safety_violation_remediation_approvals.py`
+
+Validation performed
+
+- Python `py_compile` across the touched backend files
+- `node --check` on `application/single_app/static/js/admin/admin-safety-violations.js`
+- VS Code diagnostics on the touched backend and frontend files
+
+Known limitations
+
+- `Escalate` remains unchanged because the repository does not currently include a downstream escalation workflow beyond the existing label.

+# Workflow File Sync Triggers
+
+Implemented in version: **0.241.133**
+
+Fixed/Implemented in version: **0.241.133**
+
+## Overview
+
+Workflows can now trigger configured File Sync sources before the prompt runs. The workflow can run manually, on an interval, or in Monitor File Sync Changes mode. Monitor mode checks selected File Sync sources on the configured interval and only continues into the workflow prompt when the sync detects new or changed files.
+
+## Dependencies
+
+- File Sync must be enabled for the selected personal, group, or public workspace source.
+- The current workflow owner must still be authorized for each selected File Sync source when saving and running the workflow.
+- Dynamic changed-file processing works with Analyze workflows and reuses the existing workflow document action pipeline.
+- Version was updated in `application/single_app/config.py` to `0.241.133` for the workflow trigger and run-item storage changes.
+
+## Technical Specifications
+
+- Workflows persist a `file_sync` block with selected source scope, source ID, wait mode, continue mode, and dynamic changed-document targeting.
+- A new `file_sync` workflow trigger type powers Monitor File Sync Changes mode.
+- The workflow scheduler treats `file_sync` workflows as due scheduled work and records `file_sync_monitor` as the trigger source.
+- File Sync runs now record `created`, `updated`, `changed_documents`, and `changed_document_ids` in run metadata.
+- File Sync items record `last_sync_run_id` and `last_sync_action` for traceability.
+- Workflows store durable per-document run items in the `personal_workflow_run_items` container partitioned by `run_id`.
+- Resume Failed reruns only failed document run items from a previous Analyze workflow run and disables File Sync for the retry run.
+
+## API Endpoints
+
+- `GET /api/user/workflows/file-sync-sources` returns sanitized File Sync sources the current user can select for a workflow.
+- `GET /api/user/workflows/<workflow_id>/runs/<run_id>/items` returns per-item batch tracking records for a workflow run.
+- `POST /api/user/workflows/<workflow_id>/runs/<run_id>/resume-failed` starts a follow-up workflow run for failed document items.
+
+## File Structure
+
+- `application/single_app/functions_personal_workflows.py` - workflow trigger validation, File Sync config normalization, and run-item persistence helpers.
+- `application/single_app/functions_workflow_runner.py` - File Sync pre-run execution, changed-document prompt context, dynamic Analyze targeting, and per-item tracking callbacks.
+- `application/single_app/functions_file_sync.py` - inline run support and changed-document metadata on File Sync runs/items.
+- `application/single_app/route_backend_workflows.py` - File Sync source picker, run-item list, and resume-failed endpoints.
+- `application/single_app/static/js/workspace/workspace_workflows.js` - workflow modal File Sync controls, monitor run mode, and resume-failed history action.
+- `application/single_app/templates/workspace.html` - workflow modal File Sync form controls.
+- `functional_tests/test_workflow_file_sync_triggers.py` - static functional coverage for backend and frontend contracts.
+- `ui_tests/test_workspace_workflow_file_sync_controls.py` - optional Playwright coverage for the workflow File Sync modal controls.
+
+## Usage Instructions
+
+Create or edit a personal workflow, enable File Sync Before Run, select one or more sync sources, and choose whether the workflow should always continue or only continue when files changed. For Monitor File Sync Changes, select that run mode, choose the interval, and keep the default complete-and-changed behavior.
+
+For batch document processing, choose Analyze and enable Use changed files as Analyze targets. The workflow can save without static document IDs; each run uses the documents created or updated by the File Sync pre-run.
+
+If a batch run records failed document items, open the workflow run history and select Resume failed. The follow-up run targets only the failed documents from that previous run.
+
+## Testing and Validation
+
+- Python compile coverage: `python -m py_compile` for changed backend modules.
+- JavaScript syntax coverage: `node --check application/single_app/static/js/workspace/workspace_workflows.js` and `node --check application/single_app/static/js/workspace/workspace-file-sync.js`.
+- Functional coverage: `functional_tests/test_workflow_file_sync_triggers.py`.
+- UI coverage: `ui_tests/test_workspace_workflow_file_sync_controls.py`.
+
+## Known Limitations
+
+- Monitor mode is polling-based, not a push notification from remote storage.
+- Resume Failed currently supports Analyze workflow document items.
+- Queue-only File Sync pre-runs cannot be combined with continue-only-on-change because the workflow needs completed sync metadata to know what changed.

+# Tabular Related Document Evidence
+
+Overview
+
+Implemented in version: **0.241.137**
+
+This feature extends the tabular analysis handoff so rows can carry evidence from explicitly referenced workspace documents. When a tabular row names a non-tabular file by full filename or basename, the chat route can resolve that file inside the same authorized workspace scope, retrieve a focused excerpt, and pass that evidence forward as if it were tabular-adjacent context for the same row.
+
+Dependencies
+
+- Tabular orchestration in `application/single_app/route_backend_chats.py`
+- Search and chunk retrieval helpers in `application/single_app/functions_search_service.py`
+- Workspace document metadata in `application/single_app/functions_documents.py`
+- Tabular plugin invocation payloads from `application/single_app/semantic_kernel_plugins/tabular_processing_plugin.py`
+- Functional validation in `functional_tests/test_tabular_related_document_evidence.py`
+
+Technical Specifications
+
+Architecture overview
+
+- The chat route inspects successful tabular tool results after each tabular mini-agent run.
+- Each returned row is scanned for explicit references to non-tabular workspace documents using exact filename or basename matching.
+- Matching documents are resolved within the same authorized personal, group, or public workspace scope as the tabular file.
+- The route uses the shared search service first and falls back to the first ordered chunk when search does not return an excerpt.
+- Resolved evidence is attached to each row as `referenced_documents` and summarized into the outer-model handoff message.
+- Generated tabular output prompts are aware of `referenced_documents` so exported structured results can incorporate that evidence.
+
+Scope and matching rules
+
+- The first implementation is limited to workspace documents in personal, group, and public scopes.
+- Chat-uploaded tabular files still execute normally, but related-document lookup is currently skipped for `source_hint="chat"`.
+- Only explicit file references are matched. The route does not infer document relationships from comment ids, semantic similarity, or arbitrary free text.
+- Tabular files are excluded from related-document resolution so this capability remains focused on non-tabular supporting evidence.
+
+Usage Instructions
+
+User workflow
+
+- Ask a tabular question against a workspace CSV or workbook.
+- Include or rely on rows that explicitly reference supporting files such as PDFs or DOCX files.
+- When matching workspace documents exist in the same authorized scope, the response pipeline can use excerpts from those documents alongside the computed row results.
+- Generated tabular artifacts can also use the attached `referenced_documents` row evidence when producing structured outputs.
+
+Testing and Validation
+
+Functional coverage
+
+- `functional_tests/test_tabular_related_document_evidence.py`
+- `functional_tests/test_tabular_computed_results_prompt_priority.py`
+- `functional_tests/test_tabular_generated_output_exports.py`
+
+Validation performed
+
+- `python -m py_compile application/single_app/route_backend_chats.py`
+- Focused diagnostics on `application/single_app/route_backend_chats.py`
+- Focused functional regressions covering helper matching, evidence summary handoff, prompt content, and generated-output compatibility
+
+Known limitations
+
+- Related-document matching currently depends on exact filename or basename mentions in the tabular row data.
+- The first cut does not resolve related evidence for chat-uploaded tabular files.
+- The evidence summary is intentionally capped to keep prompt growth bounded on large result sets.

+# Cosmos Throughput Autoscale
+
+Overview
+
+Implemented in version: **0.241.147**
+
+This feature adds Cosmos DB RU monitoring and guarded throughput automation to the Admin Settings Scale tab. It helps administrators monitor Cosmos DB RU pressure and automatically adjust the shared SimpleChat database throughput, or dedicated container throughput, when utilization crosses configured thresholds.
+
+Fixed/Implemented in version: **0.241.147**
+
+Enhanced in version: **0.241.148** with container-targeted throughput fallback and per-container policy controls.
+
+Enhanced in version: **0.241.161** with grouped scale-up and scale-down policy controls plus save-blocking validation for policy threshold and interval relationships.
+
+Enhanced in version: **0.241.162** with a dedicated Validate Access action that tests the current form values before admins save or enable throughput automation.
+
+Enhanced in version: **0.241.180** with container table filtering and sortable columns for container name, current RU/s, RU utilization, request units, and policy.
+
+Enhanced in version: **0.241.181** with a table-local Refresh Table action for reloading container rows beside the container filter.
+
+Enhanced in version: **0.241.183** with explicit setup guidance for the web app managed identity RBAC assignment and detailed Validate Access pass/fail diagnostics.
+
+Enhanced in version: **0.241.184** with neutral informational status copy when the environment uses container-targeted throughput instead of database-level throughput.
+
+Dependencies
+
+- Admin Settings Scale tab in `application/single_app/templates/admin_settings.html`
+- Admin settings JavaScript in `application/single_app/static/js/admin/admin_settings.js`
+- Cosmos throughput helper in `application/single_app/functions_cosmos_throughput.py`
+- Background scheduler in `application/single_app/background_tasks.py`
+- Azure Monitor metrics through `azure-monitor-query`
+- Azure Resource Manager access through `DefaultAzureCredential`
+- Deployer app settings and RBAC in `deployers/bicep/modules/appService.bicep` and `deployers/bicep/modules/setPermissions.bicep`
+
+Technical Specifications
+
+Architecture overview
+
+- The Scale tab now includes a Cosmos DB Throughput card for database identity, automation settings, live status, manual scale controls, per-container RU visibility, and a container policy modal.
+- The card header includes a Setup Guide button, while operational actions such as Refresh and Validate Access are grouped separately in the card body.
+- Current SimpleChat Bicep deployments use database-level autoscale throughput on the `SimpleChat` database, so the preferred path scales the database autoscale max RU/s.
+- Environments without database-level throughput fall back to container-targeted management for containers with dedicated throughput.
+- Container-targeted management is a normal supported capacity mode, so the Admin Settings status message is informational unless metrics or permissions fail.
+- Azure Monitor metrics provide recent normalized RU utilization and per-container request-unit visibility.
+- The per-container metrics table can be filtered by container name and sorted by container, current RU/s, RU utilization, request units, or policy.
+- The per-container metrics table includes a Refresh Table action so admins can reload rows directly from the table controls.
+- Manual Scale Up and Scale Down buttons call admin-only backend APIs.
+- Automatic scaling runs in the existing background task framework every five minutes.
+- A Cosmos-backed distributed lock prevents multiple app instances from scaling at the same time.
+
+Automation behavior
+
+- Scale up defaults to 1000 RU/s every 5 minutes when utilization reaches 90% or higher.
+- Scale down defaults to 1000 RU/s every 20 minutes when utilization is 70% or lower.
+- Scale up and scale down can be enabled or disabled independently.
+- Scale Up At must be higher than Scale Down At when automation is enabled.
+- Scale Up Interval and Scale Down Interval must be greater than or equal to the Metrics Window.
+- Minimum and maximum RU/s guardrails are available.
+- Admins can explicitly ignore the minimum or maximum guardrail when needed.
+- Runtime state is saved back into app settings for last check, last observed utilization, last scale action, and last error.
+- Validate Access runs a non-mutating setup check with the current form values and does not update the saved runtime status cache.
+- Validate Access reports each setup dependency independently: resource configuration, database throughput read, scalable throughput target discovery, container discovery, and Azure Monitor metrics read access.
+- Container-targeted runtime state stores last scale-up/down timestamps per container so cooldowns are enforced independently.
+
+Container policy controls
+
+- The Containers button opens a modal with all discovered containers.
+- Each container can be enabled or disabled for automation.
+- Each container has independent scale-up and scale-down thresholds, step sizes, cooldown intervals, minimum RU/s, maximum RU/s, and min/max ignore flags.
+- Containers using shared database throughput are shown for visibility but cannot be scaled individually until they have dedicated throughput.
+
+Security model
+
+- No Cosmos DB connection string, query surface, or management client is exposed to agents or user-defined actions.
+- Throughput operations are available only through admin-only Flask routes and the internal background scheduler.
+- The deployer adds resource metadata app settings so the backend can target the deployed Cosmos account without user-supplied resource IDs.
+- The deployer adds a custom `SimpleChat Cosmos Throughput Operator` role for the web app identity. This role allows throughput-setting reads/writes and metric reads without adding Cosmos data-plane permissions.
+- Role assignments must target the Azure App Service managed identity service principal for the running SimpleChat web app. In the Azure portal this is the Object (principal) ID shown under the Web App Identity blade, and in Microsoft Entra ID it appears as the matching Enterprise Application. Do not assign throughput-management RBAC to the user-facing Microsoft Entra sign-in app registration unless that app registration is also the credential used by the running web app.
+- Assign `SimpleChat Cosmos Throughput Operator` at the resource group scope containing the Cosmos account, or directly on the Cosmos account when a narrower scope is required.
+- The custom role includes these management-plane actions: `Microsoft.DocumentDB/databaseAccounts/read`, `Microsoft.DocumentDB/databaseAccounts/sqlDatabases/read`, `Microsoft.DocumentDB/databaseAccounts/sqlDatabases/containers/read`, database and container `throughputSettings/read`, `throughputSettings/write`, `throughputSettings/migrateToAutoscale/action`, throughput operation-result reads, and `Microsoft.Insights/metrics/read`.
+- If a deployment does not have the SimpleChat custom role, create an equivalent custom Azure RBAC role with those actions and assign it to the web app managed identity. Broad built-in roles such as Contributor can satisfy the checks but are not the recommended least-privilege path.
+- Managed identity deployments still retain the existing Cosmos Contributor role because other deployment/runtime flows depend on it.
+- Key-auth deployments can still use the system-assigned web app identity for management-plane throughput changes.
+
+Manual RBAC assignment example
+
+Use these commands when the deployer did not create or assign the throughput role automatically. Replace the placeholder values with the deployed resource names.
+
+```bash
+web_app_principal_id=$(az webapp identity show --resource-group <app-resource-group> --name <web-app-name> --query principalId -o tsv)
+cosmos_account_id=$(az cosmosdb show --resource-group <cosmos-resource-group> --name <cosmos-account-name> --query id -o tsv)
+
+az role assignment create \
+  --assignee-object-id "$web_app_principal_id" \
+  --assignee-principal-type ServicePrincipal \
+  --role "SimpleChat Cosmos Throughput Operator" \
+  --scope "$cosmos_account_id"
+```
+
+To assign at the resource group scope instead, use:
+
+```bash
+resource_group_id=$(az group show --name <cosmos-resource-group> --query id -o tsv)
+
+az role assignment create \
+  --assignee-object-id "$web_app_principal_id" \
+  --assignee-principal-type ServicePrincipal \
+  --role "SimpleChat Cosmos Throughput Operator" \
+  --scope "$resource_group_id"
+```
+
+After assigning the role, wait a few minutes for Azure RBAC propagation, then run **Validate Access** from Admin Settings. A failed result now identifies which dependency failed and preserves successful checks for comparison.
+
+API endpoints
+
+- `GET /api/admin/settings/cosmos-throughput/status`
+  - Returns configured resource metadata, database throughput mode/current RU, recent metrics, and per-container metric rows.
+- `POST /api/admin/settings/cosmos-throughput/validate-access`
+  - Accepts the current Cosmos throughput form values and validates resource configuration, database throughput read access, scalable target discovery, container discovery, and Azure Monitor metrics without saving settings or changing RU/s.
+  - Returns a `checks` array with `name`, `label`, `passed`, and `message` values so admins can see what succeeded, what failed, and the Azure error detail for failed checks.
+- `POST /api/admin/settings/cosmos-throughput/scale`
+  - Accepts `{ "direction": "up" }` or `{ "direction": "down" }` and applies the configured step and guardrails.
+  - Accepts an optional `container_name` value for dedicated container throughput scaling.

+
+Usage Instructions
+
+Admin workflow
+
+- Open Admin Settings.
+- Select the Scale tab.
+- Review the Cosmos DB Throughput card.
+- Save resource metadata if the deployed app settings do not auto-populate it.
+- Enable Cosmos throughput automation.
+- Adjust scale-up and scale-down thresholds, step sizes, cooldown intervals, and min/max guardrails.
+- Keep the Metrics Window less than or equal to both scale intervals and keep Scale Up At higher than Scale Down At.
+- Use Containers to configure per-container policies when the environment uses dedicated container throughput.
+- Use the container table filter and sortable headers to find high-utilization or high-request-unit containers quickly.
+- Use Refresh Table to reload the container rows from the same controls after changing the filter or reviewing sorted results.
+- Save Admin Settings.
+- Use Validate Access after changing resource identity or permissions to confirm the current form values work before enabling automation.
+- When Validate Access fails, review the pass/fail list. Database throughput read failures usually point to missing `throughputSettings/read`; container discovery failures point to missing `containers/read`; metric failures point to missing `Microsoft.Insights/metrics/read`; and write or conversion failures during manual actions point to missing `throughputSettings/write` or `migrateToAutoscale/action`.
+- Use Refresh to view current throughput and metrics.
+- Use Scale Up or Scale Down for guarded manual changes.

+
+Known limitations
+
+- The preferred path scales the shared `SimpleChat` database throughput because that is how the current deployer provisions Cosmos DB capacity.
+- Per-container scaling applies only to containers with dedicated throughput. Containers sharing database throughput remain visibility-only.
+- Azure Monitor metrics can lag by a few minutes, so decisions use recent observed utilization rather than instantaneous request pressure.
+- Serverless Cosmos accounts cannot be scaled by this feature.

+# Voice Assisted Form Inputs
+
+Implemented in version: **0.241.177**
+
+Fixed/Implemented in version: **0.241.177**
+
+Related config.py version update: `application/single_app/config.py` is **0.241.177** for this implementation.
+
+## Overview
+
+Voice assisted form inputs add microphone controls to speech-enabled SimpleChat form surfaces so users can dictate agent details, group and public workspace names/descriptions, document metadata, and tag names. Agent instructions can also be drafted by the configured GPT model from typed or transcribed context before the user saves the agent.
+
+## Dependencies
+
+- Admin setting `enable_speech_to_text_input` must be enabled.
+- Existing `/api/speech/transcribe-chat` Azure Speech transcription endpoint is reused.
+- Existing Azure OpenAI or APIM Chat Model is reused for agent instruction drafting.
+- Browser microphone access and `MediaRecorder` support are required for recording.
+
+## Technical Specifications
+
+- Shared browser helper: `application/single_app/static/js/form-voice-input.js`
+- Shared layout loading: `application/single_app/templates/base.html`
+- Agent instruction draft endpoint: `POST /api/agents/draft-instructions`
+- Agent modal integration: `application/single_app/templates/_agent_modal.html` and `application/single_app/static/js/agent_modal_stepper.js`
+- Manage-page refresh hooks: `application/single_app/static/js/group/manage_group.js` and `application/single_app/static/js/public/manage_public_workspace.js`
+
+The helper normalizes dictated tag names to lowercase slug-style values and normalizes dictated keyword text to comma-separated values. Textarea fields append dictated text by default, while title/name/tag fields replace the current value.
+
+## Usage
+
+When speech input is enabled, microphone buttons appear beside supported fields. Users can click a microphone button to record, click again to stop, and the transcribed text is inserted into the target field.
+
+For agents, users can dictate a brief in the Instruction Brief field and choose **Draft Instructions**. The model-generated instructions are inserted into the Markdown editor and remain editable before the user clicks Next or saves.
+
+## Testing and Validation
+
+- Functional source contract: `functional_tests/test_voice_assisted_authoring.py`
+- Optional Playwright smoke test: `ui_tests/test_voice_assisted_form_inputs.py`
+- JavaScript syntax validation: `node --check application/single_app/static/js/form-voice-input.js`
+- Backend syntax validation: `python -m py_compile application/single_app/route_backend_agents.py`
+
+Known limitation: browser and service permission failures are surfaced to the user, but the feature is unavailable when speech-to-text is disabled by configuration.

+# Agents Catalog
+
+Implemented in version: **0.241.218**
+
+## Overview
+
+The Agents Catalog adds a global **Agents** page for users to browse and launch every agent they can access from one place. The catalog combines personal agents, enabled global agents, and group agents from groups where the user is a member.
+
+UI refined through version: **0.241.231**
+
+## Technical Specifications
+
+- Frontend route: `route_frontend_agents.py` renders `/agents` behind login, user role, Swagger security, and the `enable_semantic_kernel` feature gate.
+- Backend catalog APIs: `route_backend_agents.py` exposes `/api/agents/catalog` and `/api/agents/popular`.
+- Shared catalog helper: `functions_agent_catalog.py` centralizes accessible agent serialization for both chat preload and the Agents page.
+- Agent metadata: agents now support non-secret `tags` and `icon` fields in `agent.schema.json` and `functions_agent_payload.py`.
+- Agent icons can be selected from the local Bootstrap Icons catalog or uploaded as a PNG/JPEG image. Uploaded images are resized client-side and saved as a small data image payload on the agent Cosmos record to avoid blob-storage reads for tiny avatar assets.
+- Agent usage analytics: `functions_activity_logging.log_agent_run()` records completed agent responses as `agent_run` activity log records for popularity ranking.
+- Chat rendering: selected agent icon and tags flow through selected-agent settings, chat request metadata, assistant message persistence, streaming final payloads, collaboration message serialization, and browser rendering.
+- Model icons: multi-endpoint model records support optional icon metadata, normalized through `functions_settings.normalize_model_endpoints()` and rendered in the chat model selector.
+
+## Usage Instructions
+
+- Users open **Agents** from the left navigation under **Chat** when agents are enabled.
+- The page supports search, Popular/Personal/Group/Enterprise tabs, tag filters, list view, and card view.
+- Search activates a temporary **Search Results** tab and searches across all accessible agents.
+- The **Popular** tab shows top-used accessible agents when usage data exists and supports **Most Popular All Time** and **Last 30 Days** ranking filters.
+- Popular ranking uses agent usage counts without showing implementation-oriented run counts in the main list. Agent details show **Times Used All Time** and **Times Used Last 30 Days**.
+- The **Enterprise** tab displays global agents using user-facing enterprise terminology.
+- The **Personal** tab shows a **New Agent** link when user agent creation is allowed. It opens the personal workspace Agents tab and launches the existing new-agent modal.
+- The **Group** tab shows a **New Agent** link when group agent creation is allowed. It opens the group workspace Group Agents tab without opening a modal.
+- Agent details resolve model and action display names instead of showing raw identifiers when those names are available.
+- Agent creation/edit modals support a searchable Bootstrap icon picker and an image upload mode for custom icons.
+- Agent rows/cards use workspace-style hover highlighting, open details when clicked, and use a compact information icon instead of a full Details button.
+- Agent details include instructions, scope, type, model, actions, tags, all-time usage count, and last-30-days usage count.
+- Selecting **Chat** saves the selected agent through `/api/user/settings/selected_agent` and opens the chat page with that agent selected.
+
+## Testing and Validation
+
+Functional coverage:
+
+- `functional_tests/test_agents_catalog_feature.py`
+- `functional_tests/test_global_agent_chat_selection_visibility.py`
+- `ui_tests/test_agents_catalog_details_modal.py`
+
+Validation areas:
+
+- Catalog routes and navigation are present and protected.
+- Agent tags/icons are accepted by backend payload normalization and schema validation.
+- Browser catalog rendering avoids dynamic HTML sinks for untrusted agent data.
+- Agent icon/tag metadata is preserved through chat selection and assistant message rendering.
+- Model icon metadata is normalized and exposed to the chat selector.
+

+# Agents Page Customization
+
+Documentation Version: 0.242.064
+Version Implemented: 0.241.229
+Updated in: 0.242.064
+Implemented in version: **0.241.229**
+Updated in version: **0.242.064**
+Related Config Update: `application/single_app/config.py` -> `VERSION = "0.242.064"`
+
+## Overview
+Admins can customize the public Agents page hero from the AI and Agents admin settings tab. The feature controls the hero title, subtitle, single-color or two-tone hero background, an optional markdown guidance message shown below the hero, whether agent instructions are visible in the Agents page details popup, and which agents are promoted into the Popular tab.
+
+## Purpose
+The Agents page often needs organization-specific language and curation. Admins can now explain how users should request new agents, provide contact details, add governance notes, or highlight important agents before usage counts naturally make them popular without editing templates.
+
+## Dependencies
+- Admin Settings page and existing settings persistence flow
+- `/agents` frontend route
+- Local `marked` and `DOMPurify` browser assets for markdown rendering
+- Bootstrap form controls and page layout styles
+
+## Technical Specifications
+
+### Architecture Overview
+1. `functions_settings.py` defines defaults for `agents_page_*` settings.
+2. `route_frontend_admin_settings.py` renders and persists the fields from Admin Settings.
+3. `route_frontend_agents.py` builds a sanitized public `agents_page_config` with validated hex colors.
+4. `templates/agents.html` applies the configured title, subtitle, hero colors, and markdown payload.
+5. `functions_agent_catalog.py` annotates accessible catalog records that match admin-selected Popular tab promotions. Stored catalog keys never expose agents outside the current user's normal visibility.
+6. `static/js/agents_catalog.js` renders the optional markdown disclaimer through `DOMPurify.sanitize(marked.parse(...))`, merges promoted agents into Popular rankings, and renders the optional promoted badge.
+
+### Configuration Options
+- `agents_page_title`: Hero title text.
+- `agents_page_subtitle`: Hero subtitle text.
+- `agents_page_hero_color_mode`: `single` or `two_tone`.
+- `agents_page_hero_primary_color`: Valid `#RRGGBB` primary hero color.
+- `agents_page_hero_secondary_color`: Valid `#RRGGBB` secondary color for two-tone hero mode.
+- `agents_page_disclaimer_markdown`: Optional markdown guidance text shown below the hero.
+- `agents_page_show_instructions_in_details`: Shows agent instructions in the Agents page details popup when enabled. When disabled, the Agents catalog API omits the `instructions` field for that page.
+- `agents_page_promoted_popular_agents`: Ordered list of promoted agent catalog keys with display metadata and a visibility window of `all_time`, `30_days`, or `both`.
+- `agents_page_promoted_popular_order`: Places promoted agents `before`, `after`, or `mixed` with usage-ranked agents.
+- `agents_page_promoted_popular_tag_enabled`: Controls whether promoted agents show a promoted badge.
+- `agents_page_promoted_popular_tag_label`: Badge text shown for promoted agents, defaulting to `Promoted`.
+
+### File Structure
+- `application/single_app/functions_settings.py`
+- `application/single_app/route_frontend_admin_settings.py`
+- `application/single_app/route_frontend_agents.py`
+- `application/single_app/templates/admin_settings.html`
+- `application/single_app/templates/agents.html`
+- `application/single_app/static/css/agents-catalog.css`
+- `application/single_app/static/js/agents_catalog.js`
+
+## Usage Instructions
+1. Open Admin Settings.
+2. Go to the AI and Agents tab.
+3. Use Agents Page Customization to set the title, subtitle, hero color mode, hero colors, optional guidance text, and details popup instruction visibility.
+4. In Promoted Popular Agents, select any visible agent, choose whether it appears in All Time, Last 30 Days, or both Popular views, set placement, and choose whether to show the promoted badge.
+5. Save settings.
+6. Open `/agents` to review the customized page.
+
+## Testing and Validation
+- Functional coverage: `functional_tests/test_agents_catalog_feature.py` validates defaults, admin controls, persistence wiring, sanitized disclaimer rendering, instruction visibility redaction, promoted Popular tab ranking, and the public route handoff.
+- JavaScript syntax checks cover `static/js/agents_catalog.js`.
+- Python parse checks cover the changed route/config/test files.
+
+## Known Limitations
+- The disclaimer supports markdown formatting only. Runtime JavaScript sanitization strips unsafe HTML before display.
+- Hero colors accept six-digit hex colors only.
+- Promoted Popular agents only render for users who can already access the selected agent through personal, group, or enterprise catalog rules.

+# Governance
+
+Implemented/Updated in version: **0.242.022**
+
+## Overview
+
+Governance provides administrative controls for limiting access to user, group, and global resources across endpoints, agents, and actions. It combines coarse feature-level controls with optional delegated item-level controls so administrators can decide whether a capability is open to all users or restricted to explicit users and groups.
+
+SimpleChat application-level features are governed by identity and app roles. Capabilities and resources configured inside SimpleChat, including agents, actions, endpoints, and delegated items added by admins or users, are governed by in-app governance rules. Use app roles for platform access boundaries, and use in-app governance for resources and capabilities created inside SimpleChat.
+
+The current implementation keeps backend enforcement as the source of truth. Frontend governance UI and Jinja rendering gates improve user experience by hiding disabled workspace modules before their JavaScript loads, but they are not treated as the authorization boundary.
+
+## Purpose
+
+Governance is intended to:
+
+- Restrict access to user endpoints, group endpoints, global endpoints, user agents, group agents, global agent usage, user actions, group actions, and global action usage.
+- Support allow lists containing explicit user IDs and group IDs.
+- Support one or more delegated item whitelist policies for specific endpoints, global agents, and global actions.
+- Provide admin tooling that scales to large allow lists.
+- Minimize repeated governance reads on hot API paths through request-level memoization and short-lived process caching.
+
+## Dependencies
+
+- Flask backend routes and decorators for authenticated admin/user access.
+- Cosmos DB containers for feature policies and item policies.
+- Existing settings keys that enable or disable governance checks.
+- Microsoft Graph-backed user lookup through `/api/userSearch`.
+- Group discovery through `/api/groups/discover`.
+- Bootstrap 5 modals, tables, forms, and toasts.
+- `functions_governance.py` for policy normalization, enforcement, and caching.
+- `app_settings_cache.py` for local or Redis-backed governance cache versioning.
+
+## Feature Policies
+
+Feature policies are keyed by governance setting names. Each policy stores:
+
+- `allow_all`: whether every authenticated user can access the feature when governance is enabled.
+- `allowed_users`: explicit user IDs allowed when `allow_all` is false.
+- `allowed_groups`: explicit group or workspace IDs allowed when `allow_all` is false.
+- audit metadata such as `updated_by` and `updated_at`.
+
+Supported feature policy keys:
+
+- `governance_user_endpoints`
+- `governance_group_endpoints`
+- `governance_global_endpoints`
+- `governance_user_agents`
+- `governance_group_agents`
+- `governance_global_agents_usage`
+- `governance_user_actions`
+- `governance_group_actions`
+- `governance_global_actions_usage`
+
+If a governance setting is disabled, the enforcement helper exits early and allows access. If the setting is enabled, the related feature policy must pass.
+
+## Delegated Item Policies
+
+Item policies add a second layer of control for specific delegated resources. Supported item entity types are:
+
+- `endpoint`
+- `global_agent`
+- `global_action`
+
+Item policies use the same `allow_all`, `allowed_users`, and `allowed_groups` structure as feature policies, and also include a `policy_id`, `policy_name`, and optional `resource_label`. During enforcement, the user must pass the feature policy first and then at least one item policy when policies exist for the selected resource.
+
+Multiple delegated item policies for the same resource are OR combined whitelists. A user is allowed when they are a member of any matching delegated item whitelist for that resource.
+
+Delegated item policies do not override feature-level governance. A user must pass the matching feature policy first. For example, if a user is allowed by an item policy for a specific global agent but does not pass the Global Agent Usage feature policy, the user remains blocked from that global agent.
+
+## Admin API Endpoints
+
+Governance administration is exposed through these backend routes:
+
+- `GET /api/admin/governance/policies`
+- `PUT /api/admin/governance/policies/<feature_key>`
+- `GET /api/admin/governance/item-policies`
+- `GET /api/admin/governance/item-policies/review`
+- `PUT /api/admin/governance/item-policies/<entity_type>/<item_id>`
+- `DELETE /api/admin/governance/item-policies/<entity_type>/<item_id>/<policy_id>`
+
+All governance admin routes are protected with Swagger security, login enforcement, and admin authorization.
+
+## Enforcement Flow
+
+Backend enforcement is centralized in `ensure_governance_access()` in `application/single_app/functions_governance.py`.
+
+The flow is:
+
+1. Normalize the feature key, user ID, optional item entity type, and optional item ID.
+2. Check request-level cache for an already-approved decision.
+3. Read settings and exit early if the relevant governance setting is disabled.
+4. Resolve the user's governance group IDs from group workspaces and public workspaces.
+5. Read and evaluate the feature policy.
+6. If an item entity type and item ID are provided, read all matching item policies and allow access if any item policy passes.
+7. If the feature policy fails, skip item policy evaluation and deny access. Item-level whitelists are additive only after the feature policy passes.
+8. Cache successful decisions for the remainder of the request.
+9. Raise `PermissionError` if the feature or item policy blocks access.
+
+The policy pass rules are:
+
+- `allow_all` passes immediately.
+- Empty `allowed_users` and `allowed_groups` passes for backwards-compatible default behavior.
+- The user passes if their user ID is explicitly listed.
+- The user passes if any of their resolved group/workspace IDs intersects the allowed group list.
+
+## Cache Strategy
+
+Governance is called from hot API paths, so the implementation includes two cache layers.
+
+### Request-Level Memoization
+
+Request-level cache is stored on Flask `g` using the `simplechat_governance_request_cache` attribute. It avoids repeated reads within the same HTTP request for:
+
+- settings
+- feature policies
+- item policies
+- user governance group IDs
+- successful access decisions
+
+This is the safest cache layer because it naturally expires at the end of each request.
+
+### Short-Lived Process Cache
+
+A process-level cache stores feature policies, item policies, and user governance group IDs for `60` seconds. Cache entries are deep-copied on read/write to avoid mutation leaks between callers.
+
+Process cache keys include the data type and normalized identifiers, for example:
+
+- `("feature_policy", feature_key)`
+- `("item_policies", entity_type, item_id)`
+- `("user_governance_group_ids", user_id)`
+
+The cache is guarded by an `RLock`. Each entry is stamped with the current shared governance cache version before it is stored. On read, entries are trusted only when their stamped version matches the current shared governance version and the entry has not expired.
+
+### Shared Governance Cache Version
+
+The governance cache version is exposed through `app_settings_cache.py`:
+
+- `get_governance_cache_version()`
+- `bump_governance_cache_version()`
+
+The backing store is selected automatically by the existing app cache configuration:
+
+- Redis enabled and app cache configured successfully: version is stored in Redis under `GOVERNANCE_CACHE_VERSION` and bumped with Redis `INCR`.
+- Redis disabled: version is stored in a Cosmos-backed document in the governance policies container when Cosmos is available.
+- Redis and Cosmos versioning unavailable: version falls back to local process memory.
+
+The Cosmos version document ID is `governance_cache_version`, and each worker checks it with a local `15` second version-read TTL. This keeps the governance process cache fast while allowing both Redis-enabled and non-Redis deployments to invalidate stale process-cache entries across App Service workers.
+
+### Invalidation
+
+`invalidate_governance_cache()` bumps the shared cache version and clears the current process cache. It is called when:
+
+- a feature policy is upserted
+- an item policy is upserted
+- default feature policies are bootstrapped
+
+When Redis is enabled, other processes observe the bumped Redis version before trusting their local process-cache entries. When Redis is disabled, other workers observe the bumped Cosmos version document after their local version-read TTL expires. Stale entries are dropped lazily on their next read. If both Redis and the Cosmos version read/write fail, the code falls back to process-local versioning and workers converge when their short data-cache TTL expires.
+
+## Admin UI
+
+Governance administration is hosted in the Admin Settings governance tab.
+
+Major UI areas include:
+
+- Governance feature toggles grouped by User, Group, and Global scope.
+- Feature policy table for all configured governance feature keys.
+- Delegated item policy card with on-page search, entity-type filtering, paging, and page size selection.
+- Dedicated delegated item edit modal for endpoints, global agents, and global actions.
+- Allow-list editor modal for managing users and groups.
+- Governance Configuration Guide modal explaining feature policies, workspace cohorts, delegated item policies, and evaluation flow.
+- Govern buttons on configured global endpoints, global agents, and global actions that open a prefilled delegated item policy editor.
+- Duplicate buttons for configured endpoints, agents, and actions. Endpoint duplicates start disabled, and key-based endpoint duplicates require the key to be re-entered.
+- Bootstrap toast notifications for governance status messages.
+
+Governance feature toggles also control the visible Feature Policies table. When a governance feature toggle is disabled, its matching policy row is hidden. Re-enabling the toggle immediately shows that policy row again.
+
+## Governance Configuration Guide
+
+The Governance tab includes a Configuration Guide modal. It follows the same explanatory modal pattern used by other Admin Settings areas and gives admins a compact reference for how governance works.
+
+The guide covers:
+
+- the difference between feature policies and delegated item policies;
+- how feature toggles relate to all personal, group, and global feature policy rows;
+- how group workspace membership can be reused as a governance cohort;
+- how delegated item policies narrow access to specific global resources;
+- backend evaluation order and caching behavior;
+- troubleshooting guidance for common access surprises.
+
+The most important concept is workspace cohorts. A group workspace can be used as a reusable group of users in an allow list. For example, admins can create a group workspace named **Personal Agents Pilot Users**, add pilot users to that workspace, then add that workspace ID to the **Personal Agents** feature policy's Allowed Groups list. Members can then use personal agents in their own personal workspaces.
+
+Using a group workspace as a governance cohort does **not** grant access to that workspace's documents, does **not** grant access to group agents or group actions, and does **not** move personal agents into the group workspace. It only reuses membership as an access cohort for the selected governance policy.
+
+## Delegated Item Lookup
+
+The item policy editor is a dedicated Bootstrap modal opened from the Delegated Item Policies card. The card itself lists configured policies and supports search, entity-type filtering, paging, and page size selection so admins can manage large policy sets without opening a review modal.
+
+The item policy editor uses dropdown lookup data instead of requiring admins to type IDs manually.
+
+Lookup behavior:
+
+- Endpoints are resolved from admin settings model endpoint data available on the page.
+- Global agents are loaded from `/api/admin/agents`.
+- Global actions are loaded from `/api/admin/plugins`.
+- The refresh button reloads lookup values for the selected entity type.
+- The delegated item filter narrows large lookup lists by item name, ID, or subtitle before selection.
+- Empty or failed lookups show status text near the delegated item selector.
+
+Delegated item policies are saved through a dedicated JavaScript handler in the edit modal instead of a nested HTML form, so saving a delegated item rule updates the governance item policy API rather than submitting the full Admin Settings form.
+
+Existing delegated item policies can be edited from the on-page configured policy list. The row action opens the dedicated edit modal with the selected policy loaded, including entity type, item ID, allow-all state, and explicit users/groups.
+
+When Allow All is disabled for a delegated item policy, the edit modal shows a direct principal editor. This editor supports user lookup, group lookup, CSV import, independent selected-user and selected-group search, paging, page size options, hydrated display labels, truncated IDs, and copy buttons. This keeps item policy editing usable when a delegated item contains hundreds or thousands of allowed principals.
+
+Existing delegated item policies can also be deleted from the configured policy list. Deletion uses a Bootstrap confirmation modal, calls the delegated item policy DELETE API, clears matching editor state, refreshes the configured policy list, and writes governance audit activity.
+
+The configured policy list shows hydrated user and group labels above the raw IDs. User entries show the best available display name and UPN/email, while group entries show group names. Raw IDs remain visible below the labels for traceability.
+
+## Workspace Jinja Gating
+
+Personal and group workspace templates receive a `workspace_governance` render-context object with the current user's feature-level governance decisions for agents, actions, and endpoints.
+
+When a workspace feature is enabled in settings but governance blocks the current user:
+
+- the tab remains available so the user sees why the module is unavailable;
+- the tab body renders a Bootstrap warning message explaining that the capability is disabled by governance;
+- the matching agent, action, or endpoint module JavaScript is not loaded;
+- creation/edit modals for the disabled module are not rendered;
+- endpoint lists passed to the browser are filtered through both feature and delegated endpoint item policies before sanitization.
+
+Backend API routes still enforce governance for all affected operations. The Jinja gating only prevents unnecessary UI module loading and gives users a clearer disabled state.
+
+## Allow-List Editor
+
+The allow-list editor supports both lookup-based and bulk workflows.
+
+User lookup:
+
+- Searches by display name or email through `/api/userSearch`.
+- Displays user name and email/UPN in the lookup result table.
+- Adds selected users to the working allow list.
+
+Group lookup:
+
+- Searches groups through `/api/groups/discover`.
+- Group discovery now matches group ID as well as name and description so existing selected group IDs can hydrate names.
+- Displays group name and group ID in the lookup result table.
+- Adds selected groups to the working allow list.
+
+CSV import:
+
+- Accepts one ID per line or comma-separated IDs.
+- Can target users or groups.
+- Supports merge and replace modes.
+
+## Selected User and Group List Scalability
+
+Selected allow lists are designed to stay usable with large lists.
+
+Scalability controls include:
+
+- Search within selected users and selected groups.
+- Independent pagination state for users and groups.
+- Page size options: `10`, `25`, `50`, and `100`.
+- Bounded table height with internal scrolling.
+- Previous and Next controls with disabled states at boundaries.
+- Summary text showing the currently visible range and total selected count.
+
+Search matches both raw IDs and hydrated display labels when labels are available.
+
+## Selected Row Display
+
+Selected user rows display the best available user label before the ID:
+
+- display name plus UPN/email when both are available
+- UPN/email when no display name is available
+- raw ID as fallback
+
+Selected group rows display the group name before the ID when available.
+
+Long IDs are truncated in the visible row to protect table layout. The full ID remains available through the row tooltip and the copy button.
+
+Each selected row includes a copy button that writes the full ID to the clipboard and briefly changes the icon to confirm the copy action.
+
+## Metadata Hydration
+
+Existing policies can contain raw user and group IDs without names. The allow-list editor performs best-effort metadata hydration when selected lists render.
+
+User hydration:
+
+- First tries `/api/userSearch` with the selected user ID.
+- Falls back to `/api/user/info/<user_id>`.
+- The user info endpoint first checks local user settings, then falls back to Microsoft Graph `/users/<user_id>` so selected users can display name and UPN/email even when an admin has not manually searched for that user during the current browser session.
+- Stores display name and UPN/email in the selected-list display cache.
+
+Group hydration:
+
+- Uses `/api/groups/discover` with the selected group ID.
+- Stores the group name in the selected-list display cache.
+
+Hydration is de-duplicated with in-flight tracking so repeated renders do not launch duplicate lookup requests for the same ID.
+
+## Frontend Governance Adherence
+
+Chat-facing agent and model option lists are filtered through backend governance before they are sent to the browser.
+
+Agent UI filtering applies to:
+
+- preloaded chat agent dropdown options
+- retry dialog agent options returned from user and group agent list endpoints
+- global agent usage policy and global agent item policies
+- user and group agent feature policies
+
+Model/endpoint UI filtering applies to:
+
+- global model endpoints through `governance_global_endpoints`
+- user custom model endpoints through `governance_user_endpoints`
+- group custom model endpoints through `governance_group_endpoints`
+- endpoint item policies for all endpoint scopes when an endpoint ID is available
+
+This filtering is a user-experience improvement only. Backend enforcement remains the final authorization boundary for selected agent and endpoint use.
+
+## Toast Notifications
+
+Governance UI status messages use Bootstrap toast popups.
+
+Toast handling covers:
+
+- feature policy save success
+- item policy save success
+- refresh messages
+- search/load failures
+- allow-list add/remove/clear messages
+- CSV import results
+- validation warnings
+
+A small inline fallback remains for degraded cases where Bootstrap toast support or the toast container is unavailable.

+
+## Security Notes
+
+- Backend enforcement remains mandatory and centralized in `ensure_governance_access()`.
+- Frontend controls and filtered option lists are only for administration and user experience; they are not authorization boundaries.
+- Governance admin routes require login and admin access.
+- The cache stores policy and membership decisions server-side only; it does not push full governance rules into user tokens.
+- Cache invalidation happens centrally after policy updates.
+- Redis-enabled deployments use a shared governance cache version for cross-process invalidation.
+- Redis-disabled deployments rely on the short TTL for cross-process cache convergence.
+
+## Testing and Validation
+
+Current validation includes:
+
+- governance route registration and guard checks
+- enforcement hook coverage across changed backend routes
+- cache optimization hook coverage
+- admin governance tab UI test coverage
+- JavaScript diagnostics for governance UI changes
+
+Latest verified test commands:
+
+```bash
+python -m pytest functional_tests/test_governance_route_and_wiring_coverage.py -q
+python -m pytest ui_tests/test_admin_governance_tab.py -q
+```
+
+Expected current result:
+
+- functional governance coverage passes
+- admin governance UI test may be skipped in environments where the UI preconditions are not available
+
+## Known Limitations
+
+- Redis-backed cross-process invalidation depends on Redis being enabled and successfully configured for the app cache.
+- If Redis is disabled or falls back to local memory, cross-process or cross-instance invalidation is bounded by the `60` second TTL.
+- Frontend option filtering exists for chat agent/model choices, but backend enforcement remains mandatory for all protected operations.
+- User and group display names are best-effort metadata and may fall back to raw IDs if lookups fail.
+- Clipboard copy requires browser clipboard API support.
+
+## Future Enhancements
+
+Recommended next steps:
+
+- Add a broader frontend governance bootstrap endpoint for non-chat UI gating without repeated per-control calls.
+- Add telemetry counters for cache hit/miss rates and policy block decisions.
+- Add focused tests for cache invalidation behavior with mocked governance containers.

+# App Settings Cache Versioning
+
+Implemented in version: **0.242.020**
+
+## Overview
+
+App settings cache versioning improves consistency across multiple workers while keeping settings reads fast. It preserves the existing Redis-backed shared cache for Redis deployments and adds a Cosmos-backed shared version document for non-Redis deployments.
+
+## Purpose
+
+The app reads settings frequently across routes, background work, model calls, governance checks, and UI rendering. Without Redis, each Python worker has its own in-memory settings cache. A settings update in one worker does not automatically update another worker's process memory.
+
+The versioning layer bounds that stale window without forcing every request to read the full settings document from Cosmos DB.
+
+## Cache Layers
+
+### Redis Enabled
+
+When Redis cache is enabled:
+
+- app settings are still written to Redis under `APP_SETTINGS_CACHE`;
+- a Redis version key, `APP_SETTINGS_CACHE_VERSION`, tracks settings updates;
+- each worker keeps a local in-process copy of settings;
+- each worker rechecks the shared Redis version after the local version-read TTL expires;
+- when the version changes, the worker refreshes its local settings cache from Redis.
+
+### Redis Disabled
+
+When Redis cache is disabled:
+
+- app settings are cached in each worker process;
+- the shared version document is stored in the existing `cosmos_settings_container`;
+- the version document ID is `app_settings_cache_version`;
+- each worker checks the shared Cosmos version at most once per `15` seconds;
+- when the version changes, the worker reloads the app settings document from Cosmos.
+
+The version document shape is:
+
+```json
+{
+    "id": "app_settings_cache_version",
+    "type": "cache_version",
+    "version": 42,
+    "updated_at": "2026-06-04T00:00:00.000000"
+}
+```
+
+## Write Flow
+
+When app settings are persisted:
+
+1. The `app_settings` document is upserted to Cosmos DB.
+2. The shared app settings cache version is bumped.
+3. The current worker updates its local cache immediately.
+4. Other workers observe the version change after their local version-read TTL expires.
+
+## Staleness Window
+
+The shared version read TTL is `15` seconds. In non-Redis deployments, workers can serve stale settings for up to roughly that window after another worker saves settings. This is intentional to avoid a Cosmos read on every settings lookup while still preventing indefinite worker-local staleness.
+
+## Governance Separation
+
+Governance policy cache versioning uses a separate version document in the governance policies container. App settings changes do not invalidate governance policy caches, and governance policy changes do not force workers to reload the full app settings document.
+
+## Primary Files
+
+- `application/single_app/app_settings_cache.py`
+- `application/single_app/functions_settings.py`
+- `functional_tests/test_app_settings_cache_versioning.py`
+
+## Validation
+
+Validation includes marker coverage for:
+
+- Redis app settings version keys;
+- Cosmos app settings version document IDs;
+- `15` second shared-version read TTL;
+- settings write paths that bump the shared version;
+- governance cache version fallback separation.

+# Model Endpoint Model Icon Picker
+
+Implemented in version: **0.242.060**
+Fixed/Implemented in version: **0.242.060**
+Related Config Update: `application/single_app/config.py` -> `VERSION = "0.242.060"`
+
+## Overview
+Model endpoint available-model rows now support the same icon workflow used by agent configuration: admins, personal workspace users, and group workspace owners can search local Bootstrap Icons or upload a PNG/JPEG image for each model.
+
+## Purpose
+Model choices in chat can already render model icon metadata. This feature makes that metadata practical to maintain from the shared Model Endpoint modal instead of requiring manual JSON edits or a raw icon class text field.
+
+## Dependencies
+- Shared Model Endpoint modal
+- Local Bootstrap Icons CSS asset
+- Shared agent icon helper in `application/single_app/static/js/agents_common.js`
+- Model endpoint normalization in `application/single_app/functions_settings.py`
+
+## Technical Specifications
+- `agents_common.js` now exposes generalized icon controls that accept scoped selectors while preserving the existing agent modal API.
+- `admin_model_endpoints.js` and `workspace_model_endpoints.js` render a full icon editor for every available model row.
+- Model icon payloads are saved as `{ kind: "bootstrap", value: "bi-*" }` or `{ kind: "image", value: "data:image/..." }`.
+- Existing backend normalization continues to validate model icon payloads through `normalize_icon_payload()`.
+
+## Usage Instructions
+1. Open Admin Settings, Workspace, or Group Workspace model endpoint management.
+2. Add or edit a model endpoint.
+3. In Available Models, use the Icon controls on a model row.
+4. Choose Bootstrap Icon to search local Bootstrap Icons, or Image to upload a PNG/JPEG.
+5. Save the endpoint, then save settings where required.
+
+## Testing and Validation
+- Functional coverage: `functional_tests/test_model_endpoint_model_icon_picker.py`.
+- UI coverage: `ui_tests/test_model_endpoint_request_uses_endpoint_id.py` validates the modal controls are visible and usable.
+- JavaScript parse checks cover the shared helper plus admin and workspace endpoint scripts.
+
+## Known Limitations
+- Uploaded model icons are intentionally small data images. Large images are resized client-side and rejected if they remain over the icon payload limit.

+# Outlook MSG File Ingestion
+
+Implemented in version: **0.242.063**
+Fixed/Implemented in version: **0.242.063**
+Related Config Update: `application/single_app/config.py` -> `VERSION = "0.242.063"`
+
+## Overview
+SimpleChat now accepts Outlook `.msg` files for personal workspace, group workspace, public workspace, external public workspace, and chat uploads. Uploaded messages are parsed into searchable plain text and indexed through the existing document processing pipeline.
+
+## Purpose
+Teams often store decisions, approvals, and incident context as Outlook message files. Supporting `.msg` uploads lets users add those messages to workspace knowledge and chat task-document flows without converting them to another format first.
+
+## Dependencies
+- Existing `olefile` dependency for Outlook compound document parsing.
+- Shared workspace upload routes and `allowed_file()` validation.
+- Chat upload personal and group workspace handoff.
+- Existing AI Search chunking and embedding pipeline.
+
+## Technical Specifications
+- `.msg` is represented by `EMAIL_EXTENSIONS` in `application/single_app/config.py` and merged into `get_allowed_extensions()`.
+- `extract_outlook_msg_text()` reads standard Outlook MAPI streams for subject, sender, recipients, message id, plain body, and HTML body fallback.
+- HTML message bodies are converted to plain text with BeautifulSoup after script and style removal. Message HTML is not marked trusted or rendered directly.
+- `process_msg()` chunks extracted text with the `msg` chunk-size default and saves chunks through the existing embedding and AI Search flow.
+- Chat upload support includes `.msg` in workspace-backed uploads and in the direct chat extraction fallback used when workspace upload is unavailable.
+
+## Usage Instructions
+1. Open a personal workspace, group workspace, public workspace, or chat with file uploads enabled.
+2. Upload an Outlook `.msg` file through the existing drag-and-drop area or file picker.
+3. Wait for document processing to complete.
+4. Search, summarize, analyze, or compare the uploaded message as a normal workspace document or chat-uploaded task document.
+
+## Testing and Validation
+- Functional coverage: `functional_tests/test_msg_file_upload_support.py`.
+- UI coverage: `ui_tests/test_chat_file_upload_access_control.py` verifies chat upload controls advertise `.msg` support when enabled.
+- Validation includes route decorator preservation, central allowlist coverage, processor dispatch, and XSS-safe HTML-to-text extraction boundaries.
+
+## Known Limitations
+- Embedded attachments inside `.msg` files are not recursively extracted in this release. Upload attachment files separately when they also need to be indexed.

+# Action Type Governance
+
+Implemented in version: **0.242.064**
+
+## Overview
+
+Action Type Governance lets admins delegate permission for action families such as SQL, SimpleChat, OpenAPI, MCP, Microsoft Graph, Databricks, Tableau, Chart, Azure Maps, Blob Storage, and Document Search without requiring a configured global action instance first.
+
+This complements existing configured global action policies. Action type policies grant create/use entitlement for a type; global action policies grant access to one deployed global action record with its configured endpoint, identity, credentials, and settings.
+
+## Technical Specifications
+
+Action type policies use the existing governance item policy container with these entity types:
+
+- `personal_action_type`
+- `group_action_type`
+- `global_action_type`
+
+Action type item IDs are canonicalized before storage. For example, `sql_query` and `sql_schema` both map to `sql`, so one SQL policy governs the SQL action family.
+
+The governance evaluation model is:
+
+- Broad feature policy allows access when its feature policy allows the user or group.
+- If broad access is denied, action type policies can explicitly grant access to a specific action family.
+- Missing action type policies deny access when the broad feature policy denies access.
+- Configured global action use also requires the global action record to be enabled and any configured `global_action` item policy to allow the user.
+
+## Usage Instructions
+
+Admins configure action type access from Admin Settings > Governance > Delegated Item Policies.
+
+Create a new policy and choose one of:
+
+- Personal Action Type
+- Group Action Type
+- Global Action Type
+
+Then choose the action type and assign allowed users or groups.
+
+Examples:
+
+- Allow the Finance group to create and use personal SQL actions.
+- Allow five named users to create and use SimpleChat actions.
+- Allow a reporting group to use global Tableau actions, while still restricting individual configured global Tableau actions with separate global action policies.
+
+## Testing and Validation
+
+Coverage includes:
+
+- action type policy semantics for SQL and SimpleChat
+- Personal, group, and global action type governance helpers
+- global action enabled-state, action type, and configured instance authorization chain
+- route and runtime wiring for personal, group, and global action loading
+- admin Governance UI support for action type policy entities
+
+Known limitation: action type policies currently control create and use together. Separate create-only and use-only policies can be added later if product requirements need that split.

+# Tabular SK Large Result Pagination
+
+Implemented in version: **0.242.067**
+
+## Overview
+
+Tabular Semantic Kernel analysis now supports safer large-result handling for row-returning tools. The feature adds explicit pagination metadata, preserves caller-requested projections with `return_columns`, trims oversized row payloads when projection is not provided, and raises the computed-results handoff guardrail from 24K to 100K characters.
+
+## Technical Specifications
+
+### Architecture
+
+The tabular processing plugin centralizes row payload shaping through a shared helper that:
+
+- Normalizes `start_row` and `max_rows`.
+- Returns `has_more` and `next_start_row` for continuation.
+- Applies `return_columns` projection when requested.
+- Preserves protected row metadata such as `_sheet`, `_matched_columns`, `_matched_values`, `_matched_on`, `_matched_source_values`, and `_related_document_reference_values`.
+- Estimates serialized JSON size and auto-excludes heavy non-protected columns when the row payload would exceed the safe output budget.
+- Reduces rows only when column trimming is insufficient, advancing `next_start_row` by the number of rows actually returned.
+
+### Tools Updated
+
+- `lookup_value`
+- `filter_rows`
+- `search_rows`
+- `query_tabular_data`
+- `filter_rows_by_related_values`
+
+Count and aggregation tools remain compact summary tools and do not expose row pagination.
+
+### Handoff Limits
+
+`route_backend_chats.py` now uses a 100K-character guardrail for tabular SK analysis text and computed-results handoff messages. Truncation emits warning logs with the original and configured limit details.
+
+## Usage Instructions
+
+Call row-returning tabular tools with `max_rows` to limit page size. If the tool response includes `has_more: true`, call the same tool again with `start_row` set to `next_start_row`.
+
+Use `return_columns` when the answer only needs specific fields. This bypasses automatic heavy-column exclusion and keeps returned rows focused.
+
+## Testing and Validation
+
+Functional tests:
+
+- `functional_tests/test_tabular_large_result_pagination.py`
+- `functional_tests/test_tabular_large_result_handoff.py`
+
+These tests validate row continuation, auto-trim behavior, `return_columns` projection, cross-sheet pagination, attachment-reference preservation, and the 100K handoff guardrail.
+
+## Attribution
+
+This feature was inspired by and adapted from the design direction in PR #894 by @vivche, which proposed tabular SK pagination, `return_columns` forwarding, automatic large-result trimming, and a larger computed-results handoff guardrail.
+
+The implementation in this branch was rebuilt against the current Development tabular pipeline to preserve newer model-context routing, related-document evidence, generated tabular outputs, and thought tracking.
+
+## Related Version Updates
+
+- `application/single_app/config.py` updated to `0.242.067` for the initial feature.
+- `application/single_app/config.py` updated to `0.242.068` for the Python 3.13 Semantic Kernel parameter compatibility follow-up.

+# Microsoft Teams App SSO
+
+Implemented in version: **0.242.072**
+
+## Overview
+
+SimpleChat can run as a Microsoft Teams personal tab and authenticate users with Teams Single Sign-On (SSO). The feature uses the Teams JavaScript SDK in the browser and the Microsoft identity On-Behalf-Of (OBO) flow on the Flask backend.
+
+This feature requires both a Teams app package and SimpleChat runtime configuration. The Teams package tells Teams what tab URL and Entra Application ID URI to use. The SimpleChat runtime flag enables Teams frame support, token exchange, secure cross-site session cookies, and app-level authentication handling.
+
+## Dependencies
+
+- Microsoft Teams app manifest with `webApplicationInfo` configured.
+- Entra app registration with an exposed API scope such as `access_as_user`.
+- `ENABLE_TEAMS_SSO=true` or the deployer `enableTeamsSso=true` parameter.
+- Local Teams JavaScript SDK asset at `application/single_app/static/js/MicrosoftTeams.min.js`.
+
+## Technical Specifications
+
+### Backend
+
+- `/login?teams=true` renders the Teams-aware login bootstrap page.
+- `/auth/teams/token-exchange` accepts the Teams SSO assertion, exchanges it through MSAL OBO, and creates the Flask session.
+- The token exchange endpoint is feature-gated by `ENABLE_TEAMS_SSO`.
+- The global same-origin guard also protects the pre-session Teams token exchange POST.
+- Session user data is populated from OBO ID token claims, the validated Teams assertion claims, and Microsoft Graph `/me` fallback data.
+
+### Security Headers And Cookies
+
+- When Teams SSO is disabled, `X-Frame-Options: DENY` remains active.
+- When Teams SSO is enabled, CSP `frame-ancestors` includes configured Teams origins and `X-Frame-Options` is omitted.
+- Teams SSO forces `SESSION_COOKIE_SAMESITE=None` and `SESSION_COOKIE_SECURE=true`.
+- Commercial and Azure Government defaults are provided; custom clouds can set explicit Teams origins.
+
+### Deployment
+
+- `deployers/bicep/main.bicep` exposes `enableTeamsSso`, `teamsFrameAncestors`, `customTeamsOrigins`, and `teamsAppResource`.
+- `deployers/bicep/modules/appService.bicep` sets the corresponding app settings and lets unauthenticated requests reach the app-level login flow when Teams SSO is enabled.
+- `deployers/version.txt` was updated with the deployer patch version.
+
+## Usage Instructions
+
+1. Configure the Entra app registration **Expose an API** section.
+2. Set the Application ID URI and `access_as_user` delegated scope.
+3. Preauthorize Teams client applications for that scope.
+4. Deploy SimpleChat with `enableTeamsSso=true` and `teamsAppResource` set to the Application ID URI.
+5. Build a Teams package from `application/teams_app/manifest.template.json`, `color.png`, and `outline.png`.
+6. Upload or publish the Teams package.
+7. Open the SimpleChat tab in Teams.
+
+See `docs/how-to/teams_app.md` for operator steps.
+
+## Testing And Validation
+
+- Functional tests cover Teams configuration, security header behavior, token-exchange request validation, and session user construction.
+- UI tests cover login template structure, local SDK loading, configured Teams resource usage, and fallback behavior.
+- Python syntax checks and template-focused checks validate the changed runtime files.
+
+## Known Limitations
+
+- The deployer does not publish the Teams app package; Teams app upload remains an administrator or developer action.
+- Custom or air-gapped Teams clouds must provide explicit frame ancestors, SDK origins, and Application ID URI values.
+- Teams SSO requires HTTPS because browsers require `Secure` cookies when `SameSite=None` is used.

+# Azure OpenAI Identity Setup Guide
+
+Implemented in version: **0.250.001**
+
+## Overview
+
+The Azure OpenAI identity setup guide helps admins configure GPT, embeddings, and image generation by explaining which identity is used for model discovery and which identity or secret is used for runtime generation.
+
+Dependencies:
+
+- Azure OpenAI resource
+- SimpleChat app registration/service principal
+- App Service managed identity when using managed identity runtime calls
+- Azure RBAC assignment permission on the Azure OpenAI resource
+
+## Technical Specifications
+
+Architecture overview:
+
+- Legacy GPT, embedding, and image generation `Fetch Models` buttons call SimpleChat backend routes that list Azure OpenAI deployments through Azure Resource Manager.
+- Runtime GPT, embedding, file-upload embedding, and image generation calls use the Azure OpenAI data plane.
+- The setup guide is rendered in Admin Settings near embeddings and image generation and also aligns with the global model endpoint setup guidance.
+
+API endpoints:
+
+- `GET /api/models/gpt`
+- `GET /api/models/embedding`
+- `GET /api/models/image`
+- `POST /api/admin/settings/test_connection`
+
+Configuration options:
+
+- Azure OpenAI endpoint
+- Subscription ID and resource group for model discovery
+- Key or managed identity authentication for runtime data-plane use
+- APIM endpoint, deployment, API version, and subscription key when APIM is enabled
+
+File structure:
+
+- `application/single_app/templates/admin_settings.html`
+- `application/single_app/route_backend_models.py`
+- `functional_tests/test_azure_openai_identity_split.py`
+
+## Usage Instructions
+
+Admins should assign roles on the Azure OpenAI resource before fetching or testing models:
+
+1. Assign the SimpleChat app registration/service principal `Cognitive Services User` for `Fetch Models` deployment discovery.
+2. Assign the App Service managed identity `Cognitive Services OpenAI User` when runtime generation uses managed identity.
+3. Copy the Azure OpenAI endpoint, subscription ID, and resource group from the Azure portal.
+4. Copy an Azure OpenAI key from `Keys and Endpoint` only when runtime generation uses key authentication.
+5. Use `Fetch Models` to discover deployments, then use the relevant test connection button to validate data-plane generation.
+
+## Testing and Validation
+
+Test coverage:
+
+- `functional_tests/test_azure_openai_identity_split.py`
+- `functional_tests/test_azure_openai_deployer_role_split.py`
+
+Performance considerations:
+
+- Model discovery is an admin operation and only lists deployment metadata.
+- Runtime embedding and image calls are unchanged by the setup guide.
+
+Known limitations:
+
+- API keys do not authorize management-plane model discovery.
+- Foundry provider role setup is handled separately by the global model endpoint setup guide.
+
+Config version updated in `application/single_app/config.py` to **0.250.001**.

+# Snowflake Action
+
+Implemented in version: **0.250.006**
+
+Version reference: `application/single_app/config.py` was updated to `VERSION = "0.250.006"` for this feature.
+
+Dependencies: Snowflake Connector for Python with pandas extras, Semantic Kernel action loading, workspace identities, and Key Vault action secret handling.
+
+## Overview
+
+The Snowflake action adds a built-in Semantic Kernel plugin type, `snowflake`, for querying Snowflake data warehouses from SimpleChat agents. It is designed for data retrieval and analysis, not Snowflake administration or data management.
+
+Agents can use the action to discover databases, schemas, tables, and table columns, then execute read-only SQL queries and use the returned tabular rows for analysis, charts, generated documents, exports, or other user-requested outputs.
+
+## Technical Specifications
+
+### Architecture
+
+- Plugin type: `snowflake`
+- Default endpoint: `snowflake://query`
+- Backend plugin: `semantic_kernel_plugins/snowflake_plugin.py`
+- Factory: `semantic_kernel_plugins/snowflake_plugin_factory.py`
+- Shared normalization helpers: `functions_snowflake_operations.py`
+- UI configuration: `templates/_plugin_modal.html` and `static/js/plugin_modal_stepper.js`
+- Connector dependency: `snowflake-connector-python[pandas]==3.14.0`
+
+### Authentication
+
+The action supports:
+
+- Password authentication through `auth.type = username_password`
+- Key-pair authentication through `auth.type = key` and `additionalFields.auth_method = key_pair`
+- OAuth token authentication through `auth.type = key` and `additionalFields.auth_method = oauth`
+- Reusable workspace identities for username/password, API key private-key material, and bearer-token OAuth flows
+
+Secrets are handled through the existing action Key Vault paths. Passwords, private keys, private key passphrases, and OAuth tokens are redacted and resolved server-side when Key Vault secret storage is enabled.
+
+### Query Safety
+
+The Snowflake action enforces read-only execution by default:
+
+- Allows `SELECT`, `WITH`, `SHOW`, `DESCRIBE`, `DESC`, and `EXPLAIN`
+- Rejects multiple statements in one call
+- Blocks write, DDL, staging, role, and system-function keywords such as `INSERT`, `UPDATE`, `DELETE`, `CREATE`, `DROP`, `PUT`, `COPY`, `GRANT`, `USE`, and `SYSTEM$`
+- Adds `LIMIT` to `SELECT` and `WITH` queries that do not already include `LIMIT` or `FETCH`
+- Caps returned rows and serialized result size
+
+### Semantic Kernel Functions
+
+The plugin exposes:
+
+- `execute_sql_query(query)`
+- `get_databases()`
+- `get_schemas(database="")`
+- `get_tables(database="", schema="")`
+- `describe_table(table_name)`
+
+Each query response includes query metadata, columns, row dictionaries, row counts, and truncation status.
+
+## Usage Instructions
+
+1. Add a new action and select **Snowflake**.
+2. Enter the Snowflake account identifier, warehouse, and optional default database, schema, and role.
+3. Choose password, key-pair, OAuth token, or a reusable identity.
+4. Configure row and timeout limits.
+5. Assign the action to agents that should analyze Snowflake data.
+
+Agents should use the discovery functions before writing SQL so generated queries reference valid Snowflake objects.
+
+## Testing and Validation
+
+Functional coverage lives in `functional_tests/test_snowflake_action_plugin.py` and validates:
+
+- Manifest defaults and factory normalization
+- Health checker validation
+- Read-only query rejection before connector access
+- Automatic `LIMIT` handling
+- Structured columns/rows result shape
+- Discovery helper SQL generation
+
+Known limitation: the functional test uses a fake connector and does not validate live Snowflake network connectivity or account-level permissions.

+# Action Workspace Identity Scope Fix
+
+Fixed/Implemented in version: **0.241.095**
+
+Related version update: `application/single_app/config.py` was incremented to `0.241.095` for this fix.
+
+## Issue Description
+
+Reusable workspace identities existed for File Sync, but the action creation workflow did not load or bind the scoped identity catalog. SQL actions still required action-local credentials, so an action-capable identity selected in the identity manager did not appear in the action modal.
+
+## Root Cause Analysis
+
+The identity framework already stored personal, group, public, and global identities with usage metadata, and File Sync resolved them through `functions_workspace_identities.py`. The action workflow did not have equivalent integration:
+
+- The shared action modal did not call the workspace identity APIs.
+- Personal, group, and global action save paths did not validate identity references against their owning scope.
+- SQL connection testing and runtime plugin loading could not resolve identity-backed credentials.
+- Identity deletion only checked File Sync references and skipped global identities entirely.
+
+## Technical Details
+
+Files modified:
+
+- `application/single_app/functions_workspace_identities.py`
+- `application/single_app/functions_personal_actions.py`
+- `application/single_app/functions_group_actions.py`
+- `application/single_app/functions_global_actions.py`
+- `application/single_app/route_backend_plugins.py`

+- `application/single_app/semantic_kernel_plugins/sql_schema_plugin.py`
+- `application/single_app/semantic_kernel_plugins/plugin_health_checker.py`
+
+Code changes summary:
+
+- Added `identity_id` as the explicit action manifest reference for reusable identities.
+- Added scope-aware action identity validation and runtime hydration helpers.
+- Added personal, group, and global action save validation so identities cannot cross scope boundaries.
+- Added SQL action modal identity selectors for personal, group, and global action contexts.
+- Added SQL connection test identity resolution without trusting caller-supplied group or global scope ids.
+- Updated SQL plugin runtime connection building to preserve managed identity auth mode.
+- Updated SQL plugin health validation so connection-string identities do not require copying the connection string into the action manifest.
+- Updated identity deletion safeguards to block deletes when identities are referenced by actions or File Sync.
+- Limited public identities to public File Sync and global identities to global actions.
+
+## Validation
+
+Test coverage:
+
+- `functional_tests/test_action_workspace_identity_scoping.py`
+- `ui_tests/test_workspace_action_identity_modal.py`
+- `functional_tests/test_file_sync_capability.py` version assertion updated for `0.241.095`
+
+Before:
+
+- A SQL action could not select an existing action-capable identity.
+- Action saves could not validate identity scope ownership.
+- Runtime action loading had no server-side identity hydration path.
+- Global identities could be deleted without checking action references.
+
+After:
+
+- Personal actions use only personal identities.
+- Group actions use only identities from the active group.
+- Public workspace identities remain File Sync-only.
+- Global identities use global actions only.
+- Action manifests store identity references instead of copied secrets.

+# Advanced Conversation Search Fix - Version 0.241.097
+
+## Issue Description
+
+The left sidebar conversation search used client-side partial title matching, while the Advanced Search modal used a backend message-only path with stricter chat type filtering and legacy-only message storage. Searches such as `Chase` could miss recent conversations whose titles or collaborative messages contained related terms such as JP Morgan Chase.
+
+## Root Cause Analysis
+
+Advanced search had three gaps:
+
+* The default modal chat type values did not align with stored values such as `personal_single_user`, `personal_multi_user`, and `group_multi_user`.
+* The backend searched `cosmos_messages_container` but did not search collaborative conversations and messages stored in the collaboration containers.
+* Results were only built from message matches, so conversation title matches found by the sidebar search path were not included in advanced results.
+
+## Fixed/Implemented in version: **0.241.097**
+
+The application version was updated in `application/single_app/config.py` from `0.241.096` to `0.241.097` for this fix.
+
+## Technical Details

+* Added explicit advanced search match modes: contains partial text, all words, any word, and whole word.
+* Kept `contains` as the default mode so substring searches such as `Chase` can match larger tokens such as `JPMorganChase`.
+* Normalized chat type filters so modal values map to stored personal, group, and collaboration chat type values.
+* Included accessible collaborative conversations and `cosmos_collaboration_messages_container` messages in advanced search.
+* Included conversation title matches in advanced search results, with title-only results opening the matching conversation.
+* Parameterized Cosmos text search queries to avoid interpolating search terms into query text.
+
+### Testing Approach
+
+* Added a functional test for partial matching, match modes, chat type aliasing, parameterized message queries, collaboration search route contracts, and version/documentation alignment.
+* Added an optional Playwright UI test that verifies the modal sends the selected match mode and normalized multi-user group filter to `/api/search_conversations`.
+
+## Impact Analysis
+
+Advanced Search now behaves more like the left sidebar search while preserving richer filters. It searches both titles and message content across legacy and collaborative conversation stores, and users can choose narrower whole-word or broader word-token behavior when needed.
+
+## Validation
+
+Before the fix, advanced search could miss recent collaborative/title-only results and could silently filter out stored chat types that did not exactly match modal values.
+
+After the fix, searches such as `Chase` use partial matching by default, include conversation titles, include collaboration messages, and support explicit match modes for broader or narrower searches.

+# Anthropic Analyze/Compare Workflow Stream Fix (v0.241.193)
+
+Fixed/Implemented in version: **0.241.193**
+
+## Issue Description
+
+Chat and workflow Analyze/Compare document actions could fail after selecting a Claude or Anthropic model endpoint. The chat document-action stream surfaced the failure while the underlying workflow execution still built an Azure OpenAI client for selected workflow model endpoints.
+
+Anthropic streaming calls could also fail or hide useful provider errors because stream requests used an `application/json` accept header and Anthropic SSE `error` events were ignored by the OpenAI-shaped adapter.
+
+## Root Cause Analysis
+
+The chat streaming model endpoint builder was already protocol-aware, but the workflow runner's selected model endpoint resolver always instantiated Azure OpenAI clients. Analyze/Compare actions invoked through workflow execution therefore did not preserve the Anthropic protocol selection for Claude deployments.
+
+The Anthropic adapter also treated all requests as JSON responses at the header level and only parsed successful SSE data events. Provider-side stream errors could pass through as an empty or incomplete response instead of a clear runtime failure.
+
+## Technical Details
+
+Files modified:
+
+- `application/single_app/model_endpoint_clients.py`
+- `application/single_app/functions_workflow_runner.py`
+- `application/single_app/config.py`
+- `functional_tests/test_analyze_compare_claude_workflow_stream.py`
+
+Code changes summary:
+
+- Routed workflow-selected Claude/Anthropic model endpoints through `build_anthropic_chat_client` instead of Azure OpenAI client construction.
+- Preserved OpenAI-compatible Foundry endpoint behavior through `build_openai_style_chat_client` for non-Claude project endpoints.
+- Sent `Accept: text/event-stream` for Anthropic stream requests.
+- Surfaced Anthropic SSE `error` events as clear runtime errors and preserved stream usage metadata.
+- Added regression coverage for Claude workflow endpoint resolution, OpenAI-style endpoint preservation, Anthropic SSE parsing, and chat document-action stream wiring.
+- Updated `application/single_app/config.py` to version **0.241.193**.
+
+## Validation
+
+Test results:
+

+
+Before this fix, Analyze/Compare actions using Claude model endpoints could fail inside workflow execution or produce unclear stream failures. After this fix, chat and workflow Analyze/Compare paths resolve Claude endpoints through the Anthropic adapter and report Anthropic stream provider errors cleanly.

+# Assigned Knowledge Active Documents UI Fix
+
+Fixed in version: **0.241.117**
+
+Updated in version: **0.241.118**
+
+Updated in version: **0.241.119**
+
+## Issue Description
+
+Agent creators could select a public workspace source and see many resolved documents, then move to the Documents section and accidentally reduce the final document set to only one document. The page did not clearly explain that sources create the document pool, tags and specific documents are optional limits, and the resolved document list is the final set used by the agent.
+
+A follow-up issue showed that the agent workflow modal was not wide enough for the Assigned Knowledge two-column pickers, and that the public workspace source picker only listed workspaces visible in the user's normal public workspace directory instead of all searchable public workspaces.
+
+Another follow-up issue showed that inventory questions such as "what documents do you have access to" were answered from the top retrieved citations instead of the full active Assigned Knowledge document set. Personal agents assigned to public workspace knowledge could also become public-scope conversations after retrieval, causing the personal agent to disappear from the locked conversation's agent picker.
+
+## Root Cause Analysis
+
+The Knowledge step used internal wording such as Sources, Documents, and Resolved Documents without explaining the workflow. The preview also treated selected tags as any-tag matches, while backend search requires documents to match all selected tags before they qualify through tag limits.
+
+## Technical Details
+
+### Files Modified
+
+- `application/single_app/templates/_agent_modal.html`
+- `application/single_app/static/js/agent_modal_stepper.js`
+- `application/single_app/functions_assigned_knowledge.py`
+- `application/single_app/functions_search.py`

+- `functional_tests/test_assigned_knowledge_active_documents_ui.py`
+- `ui_tests/test_agent_modal_assigned_knowledge_step.py`
+
+### Code Changes Summary
+
+- Added a question-mark help button to the Assigned Knowledge step with concise workflow guidance.
+- Renamed the authoring model around Source Workspaces, Tag Limits, Specific Documents, and Active Documents.
+- Added a live active-document summary near the top of the controls.
+- Updated active-document counts and empty states so users can see when they are using all source documents versus a narrowed set.
+- Aligned the browser preview with backend tag behavior by requiring every selected tag limit to match before a document is included by tags.
+- Widened the agent workflow modal from the large Bootstrap modal to an extra-large bounded dialog.
+- Updated the Assigned Knowledge public source catalog to list all public workspaces, not only the user's directory-visible public workspaces.
+- Added an Assigned Knowledge search path override so assigned public workspaces are searched even when they are hidden from the user's normal public workspace selector.
+- Added a backend active-document inventory resolver for Assigned Knowledge.
+- Added deterministic chat augmentation for Assigned Knowledge inventory questions so answers can state and list the full active document set.
+- Kept personal Assigned Knowledge agents anchored to personal conversation metadata while tracking assigned public workspaces as additional locked context.
+- Updated `application/single_app/config.py` to version `0.241.119`.
+
+### Testing Approach
+
+- Added a functional regression test for the modal wording and JavaScript preview contract.
+- Updated the Assigned Knowledge UI test to validate the new active-document summary and all-tag matching behavior.
+- Ran JavaScript syntax checks and targeted Python validation for changed tests.
+
+## Impact Analysis
+
+This change is UI-focused and does not alter stored Assigned Knowledge payloads or backend runtime filters. It reduces accidental over-narrowing by making the final active document set more prominent and by explaining when the Documents section should be used.
+
+## Validation
+
+The updated UI now makes the final document set visible as Active Documents, clarifies that source workspaces alone use all documents from those sources, and describes tag/document selections as optional limits. The browser preview now matches the backend all-tag filter semantics, avoiding misleading active-document counts before the agent is saved.

+# Assigned Knowledge Task Context Split Fix (v0.241.207)
+
+Version: 0.241.207
+
+Fixed/Implemented in version: **0.241.207**
+
+Related config.py version update: `application/single_app/config.py` now sets `VERSION = "0.241.207"`.
+
+## Issue Description
+
+Assigned knowledge and user-uploaded task documents could be treated too similarly in chat workflows. In public/global agent flows, this could cause the agent to answer from assigned knowledge while a newly uploaded task document was still being indexed, or require the user to manually select Analyze even though the uploaded document was already linked to the conversation.
+
+## Root Cause Analysis
+
+- Assigned knowledge was primarily wired through the normal workspace search path.
+- Analyze and Compare executed against selected document IDs, but did not automatically search assigned knowledge as agent reference context.
+- Normal Search could continue with assigned knowledge only when a conversation-linked upload existed but was not search-ready yet.
+
+## Technical Details
+
+### Files Modified
+
+- `application/single_app/route_backend_chats.py`
+- `application/single_app/config.py`
+- `functional_tests/test_chat_upload_personal_workspace_handoff.py`
+
+### Code Changes Summary
+
+- Added a top-12 assigned-knowledge reference search helper for agent document actions.
+- Enriched Analyze and Compare prompts with assigned-knowledge reference excerpts without adding assigned knowledge documents to the task document IDs.
+- Added assigned-knowledge context citations to document-action responses.
+- Added a backend pending-upload guard for normal and streaming Search so an agent cannot answer from assigned knowledge alone while uploaded task documents are still processing.
+- Preserved user-selected and conversation-linked uploads as the task document corpus.
+
+### Testing Approach
+
+- Updated the chat upload handoff functional source-contract test to validate the assigned-knowledge/task-document split.
+- Added assertions for fixed top-12 assigned-knowledge search, prompt enrichment, citation merging, task-document hint usage, and pending-upload Search blocking.
+
+## Impact Analysis
+
+- Public/global agents can use public assigned knowledge as reference context while analyzing or comparing uploaded personal task documents.
+- Assigned knowledge remains agent context by default, not an implicit task document selection.
+- Users receive a clear processing response when they upload a document and ask the agent to use it before indexing is complete.
+
+## Validation
+
+Expected validation commands:
+
+```powershell
+python -m py_compile application/single_app/route_backend_chats.py functional_tests/test_chat_upload_personal_workspace_handoff.py
+python functional_tests/test_chat_upload_personal_workspace_handoff.py
+```
+
+Before this fix, an agent could fall back to assigned knowledge and say uploaded document text was unavailable. After this fix, assigned knowledge is searched as reference context, uploaded/selected documents remain task documents, and pending uploads produce an explicit processing response.

+# AZD Managed Identity Preflight Fix
+
+Fixed in version: **0.242.057**
+Deployer version: **1.0.15**
+
+## Issue Description
+
+When an AZD deployment selected `managed_identity`, the deployment could proceed until Azure role-assignment creation failed or, in some script paths, continue after warnings that were easy to miss. That made it possible for deployment output to look successful while the application identity did not have the RBAC access required at runtime.
+
+## Root Cause Analysis
+
+Managed identity deployment depends on Azure RBAC assignments for the App Service identity and related resources. The deployer created those assignments during provisioning, but the preprovision validation did not check whether the signed-in Azure identity could create role assignments or custom role definitions before longer-running deployment work began.
+
+## Technical Details
+
+Files modified:
+
+- `deployers/bicep/validate_azd_prerequisites.py`
+- `deployers/bicep/README.md`
+- `deployers/version.txt`
+- `application/single_app/config.py`
+- `functional_tests/test_azd_managed_identity_preflight.py`
+
+Code changes summary:
+
+- Added a managed identity preflight check to the AZD preprovision script.
+- The check only runs when `AUTHENTICATION_TYPE` resolves to `managed_identity`.
+- The check validates effective Azure permissions for `Microsoft.Authorization/roleAssignments/write` and `Microsoft.Authorization/roleDefinitions/write` at the target deployment scopes.
+- The deployer now fails fast if `CONFIGURE_APPLICATION_PERMISSIONS=false` is paired with managed identity automation.
+- Failure guidance tells users to rerun with an Azure identity that has Owner, Role Based Access Control Administrator, or equivalent custom permissions, or to switch to key-based authentication with `azd env set AUTHENTICATION_TYPE key` if that model is acceptable.
+- Updated `application/single_app/config.py` to version `0.242.057` and `deployers/version.txt` to deployer version `1.0.15`.
+
+## Validation
+
+Functional coverage is provided by `functional_tests/test_azd_managed_identity_preflight.py`.
+
+Before the fix, managed identity permission gaps could surface late or be hidden behind postprovision warnings. After the fix, managed identity deployments stop during preprovision with a clear explanation and remediation path.

+# AZD Windows Hook Environment and Auth Diagnostic Fix - Version 0.241.101
+
+## Header Information
+
+**Issue description:** On Windows, `azd deploy` could fail in the `predeploy` hook with `Unable to resolve resource group from var_rgName, Cosmos DB, or Web App` even when the active azd environment contained `var_rgName`, Cosmos DB, and Web App outputs.
+
+**Root cause analysis:** The Windows hook scripts read deployment outputs from `$env:var_*` process environment variables. In this azd execution path, the values were available through `azd env get-value` but were not present in the hook process environment, so the resolver treated the resource group, Cosmos DB account, and Web App name as missing. A second failure mode occurred when Azure CLI returned `Need user interaction to continue` for management-plane lookups; the hook suppressed that stderr and fell through to the same generic resource-group error.
+
+**Fixed in version:** **0.241.101**
+
+**Related version updates:** `application/single_app/config.py` was updated to `0.241.101`, and `deployers/version.txt` was updated to `1.0.9` for the deployer workflow change.
+
+## Technical Details
+
+**Files modified:**
+
+- `deployers/azure.yaml`
+- `deployers/version.txt`
+- `application/single_app/config.py`
+- `functional_tests/test_azd_windows_hook_environment.py`
+
+**Code changes summary:** The Windows `postprovision`, `predeploy`, and `postup` hooks now call an `Import-AzdHookEnvironment` helper before subscription or resource-group resolution. The helper keeps existing process environment values intact, and hydrates missing values from the active azd environment through `azd env get-value`. Resource lookup commands now preserve Azure CLI error output and detect interactive-auth failures so the hook can tell the operator to run `az login --scope "https://management.core.windows.net//.default"` instead of reporting a missing resource group.
+
+**Testing approach:** Added a functional regression test that validates the affected Windows hooks import required `AZURE_SUBSCRIPTION_ID` and `var_*` values before calling the resource resolver or deployer commands, and preserve Azure CLI auth failure output for diagnostics.
+
+**Impact analysis:** Windows `azd deploy` can now resolve stored deployment outputs consistently when the values exist in `.azure/<environment>/.env` but are not exposed as process environment variables. POSIX hook behavior is unchanged.
+
+## Validation
+
+**Test results:** `functional_tests/test_azd_windows_hook_environment.py` validates the hook hydration and auth diagnostic wiring.
+
+**Before/after comparison:** Before the fix, Windows predeploy could fail before stopping the Web App or starting the ACR build because `$env:var_rgName` and fallback resource identifiers were empty, or because Azure CLI needed interactive management-plane authentication and the hook hid that message. After the fix, the hook hydrates deployment values from azd environment storage before resource resolution and reports Azure CLI interactive-auth requirements directly.
+
+**User experience improvements:** Re-running `azd deploy` from `deployers` should no longer require manually exporting `var_rgName` or related deployment outputs in the PowerShell session.

+# Azure Maps Inline Artifact Hydration Fix
+
+Fixed in version: **0.241.050**
+
+## Issue Description
+
+Inline Azure Maps cards could fail during OpenLayers initialization even when the full map artifact existed. The browser console showed errors like `Cannot assign to read only property '0' of string '<list with 2 items>'`, and the card fell back to the generic initialization failure message instead of rendering the map.
+
+## Root Cause Analysis
+
+- The inline renderer in `chat-inline-maps.js` accepted compact citation payloads before artifact hydration when `function_result` already contained a shallow `render_type` and `map_payload` preview.
+- Compact assistant citation payloads replace deep list and object values with placeholders such as `<list with 2 items>` and `<dict with 6 keys>`, which are not valid coordinate arrays for OpenLayers.
+- The renderer did not normalize or reject those placeholder coordinate shapes before calling `ol.proj.fromLonLat(...)`.
+
+## Version Implemented
+
+- **0.241.050**
+
+## Files Modified
+
+- `application/single_app/static/js/chat/chat-inline-maps.js`
+- `ui_tests/test_chat_inline_azure_maps_rendering.py`
+- `functional_tests/test_azure_maps_inline_artifact_hydration_fix.py`
+
+## Code Changes Summary
+
+- Updated the inline Azure Maps renderer to prefer hydrated artifact payloads whenever `raw_payload_externalized` is present.
+- Added coordinate, marker, area, and view normalization so compact placeholder shapes are rejected instead of being passed into OpenLayers.
+- Strengthened the UI test to reproduce the compact-payload preview case while still requiring artifact hydration to succeed.
+- Added a functional regression test to lock the renderer contract in environments where browser UI tests are skipped.
+
+## Testing Approach
+
+- Added `functional_tests/test_azure_maps_inline_artifact_hydration_fix.py`.
+- Updated `ui_tests/test_chat_inline_azure_maps_rendering.py` so the compact citation preview includes invalid placeholder coordinate data and still expects artifact hydration.
+
+## Impact Analysis
+
+- Inline Azure Maps cards now render from the full hydrated payload instead of failing on compact preview placeholders.
+- Compact externalized citations remain safe for storage while the UI still gets the full geometry needed for OpenLayers.
+
+## Validation
+
+- Before: compact citation previews could pass the render-type guard and crash during `fromLonLat(...)`.
+- After: the renderer hydrates the full artifact first, normalizes geometry, and only initializes OpenLayers with valid coordinate arrays.

+# Azure Maps Tile Proxy Token Refresh Fix
+
+Fixed in version: **0.241.063**
+
+## Issue Description
+
+Older chat messages that contained inline Azure Maps visualizations could stop loading map tiles after the stored proxy token expired. The browser then showed repeated `400` responses from `/api/azure-maps/tile`, while the backend logged `Rejected an expired Azure Maps tile proxy token.`
+
+## Root Cause Analysis
+
+- The Azure Maps visualization plugin stores a secure proxy tile URL template inside the citation payload.
+- That URL template contains an encrypted proxy token with a limited lifetime.
+- When an older message was reopened after the token expired, the app could still return the original stored tile URL template instead of reissuing a fresh proxy token.
+- Some older assistant messages also persisted a legacy `{{map:...}}` content block that embedded the original tile URL template directly in message text.
+- The Azure Maps subscription key itself was still valid; only the stored proxy token had aged out.
+
+## Version Implemented
+
+- **0.241.063**
+
+## Files Modified
+
+- `application/single_app/functions_azure_maps.py`
+- `application/single_app/functions_message_artifacts.py`
+- `application/single_app/route_frontend_conversations.py`
+- `functional_tests/test_azure_maps_tile_token_refresh_fix.py`
+
+## Code Changes Summary
+
+- Added helper functions to refresh Azure Maps tile proxy tokens and rebuild tile URL templates from stored encrypted payloads.
+- Updated artifact hydration so Azure Maps citations get a freshly issued tile URL template before they are returned to the client.
+- Updated the agent citation artifact endpoint to refresh Azure Maps citation payloads before serializing the response.
+- Updated conversation message loading so assistant citations are hydrated from artifacts before the chat UI renders them.
+- Updated conversation message loading to refresh all Azure Maps citations in the returned message payload, even when the client falls back to the compact citation.
+- Updated conversation message loading to refresh embedded legacy `{{map:...}}` content blocks before serializing assistant messages.
+- Updated the inline Azure Maps renderer to prefer artifact-backed payloads whenever an artifact id is available for the citation.
+- Updated AI message rendering to strip legacy `{{map:...}}` blocks from visible markdown so the raw payload no longer appears in chat text.
+- Disabled browser caching on conversation-message and agent-citation artifact responses so stale expired tile URLs are not reused from cache.
+- Updated the chat message and artifact fetches to request `no-store` responses and append a cache-busting timestamp.
+- Added a regression test that verifies expired stored tile URLs are reissued automatically during hydration.
+
+## Testing Approach
+
+- Added `functional_tests/test_azure_maps_tile_token_refresh_fix.py`.
+- Validated direct tile URL template refresh, artifact-hydration refresh, inline message-content refresh, the conversation-load contract, and the no-store fetch contract using an intentionally expired stored proxy token.
+
+## Impact Analysis
+
+- Existing chat messages with inline Azure Maps visualizations now recover automatically without requiring a new Azure Maps subscription key.
+- The browser receives a fresh proxy tile URL template when the visualization is loaded, so the map tiles render again instead of returning `400` errors.
+- The conversation history endpoint now refreshes agent citation payloads before the UI renders them, which closes the path that could still reuse compact stale map payloads after a server restart.
+- Older assistant messages that still contain legacy `{{map:...}}` blocks now have their embedded tile URLs refreshed server-side, and the raw block is hidden from rendered chat text.
+- Browser caching is now bypassed for the conversation JSON and agent-citation artifact JSON, which prevents the page from reusing an old expired `tile_url_template` after a normal reload.
+
+## Validation
+
+- Before: reopening older Azure Maps messages reused an expired tile token and tile requests failed with `400`.
+- After: stored Azure Maps citation payloads are refreshed server-side before the client renders the map, so tile requests use a valid proxy token.

+# Broken Access Control Findings Fix
+
+Fixed/Implemented in version: **0.242.049**
+
+## Issue Description
+
+The Broken Access Control audit identified several places where caller-controlled object identifiers were used before a fresh authorization decision for the exact object. The affected paths included workflow conversation bindings, SimpleChat plugin conversation tool calls, and group document deletion.
+
+## Root Cause Analysis
+
+Workflow save helpers accepted arbitrary `conversation_id` values and workflow execution later reused those conversation records without confirming that the conversation belonged to the workflow owner or active group. SimpleChat plugin helper calls could return distinguishable errors for missing, foreign, and wrong-type conversation IDs. The group document delete route read a caller-provided document ID directly before proving that it belonged to the active group.
+
+## Technical Details
+
+Files modified:
+
+- `application/single_app/functions_personal_workflows.py`

+- `application/single_app/route_backend_group_documents.py`
+- `functional_tests/test_broken_access_control_findings_fix.py`
+- `application/single_app/config.py`
+
+Code changes summary:
+
+- Added save-time workflow conversation validation for personal and group workflows.
+- Added a workflow-runner backstop so already-persisted foreign conversation IDs cannot be reused for workflow message writes.
+- Collapsed SimpleChat plugin conversation lookup failures to a generic not-found/access-denied response.
+- Added an authorized collaboration invite boundary before participant management logic.
+- Changed group document deletion to query by both document ID and owning active group before delete processing.
+- Replaced raw `activeGroupOid` reads in group document routes with a `require_active_group(...)`-backed resolver.
+
+## Validation
+
+Testing approach:
+
+- Added a focused functional regression test that verifies personal/group workflow conversation validation, workflow runner authorization, SimpleChat plugin conversation oracle collapse, scoped group document deletion source structure, and removal of raw active-group reads from group document routes.
+
+Before/after comparison:
+
+- Before: known foreign conversation or document IDs could produce distinguishable responses, and workflow runs could write into an unauthorized conversation.
+- After: workflow conversation IDs are authorized at save and execution time, plugin tool-call lookups collapse unauthorized targets, group document routes resolve the active group through an authorization helper, and group delete requests only proceed after a scoped owning-group document lookup succeeds.
+
+Related version update:

+- `application/single_app/config.py` was incremented from `0.242.048` to `0.242.049`.

+# Chat Activity Logging Consistency Fix
+
+Fixed/Implemented in version: **0.241.102**
+
+## Issue Description
+
+Chat activity logging was inconsistent across message flows that should be tracked the same way for reporting and downstream UI surfaces.
+
+- Standard chat messages emitted `chat_activity` telemetry but did not create a matching record in the `activity_logs` Cosmos container.
+- Document analysis and compare requests saved the user message but skipped the shared chat activity logger entirely.
+- Multi-user collaboration messages saved successfully but did not emit the shared chat activity event used by the rest of chat.
+- Control Center Activity Logs did not expose `chat_activity` as a first-class filter or render document-action and collaboration rows with useful message context.
+
+Related config update: `application/single_app/config.py` now sets `VERSION = "0.241.102"`.
+
+## Root Cause Analysis
+
+- The shared `log_chat_activity(...)` helper only wrote to App Insights even though its callers treated it as the common chat tracking path.
+- The document-action request handler in `application/single_app/route_backend_chats.py` persisted the user message through a dedicated flow that never called the shared helper.
+- Collaborative message persistence in `application/single_app/functions_collaboration.py` updated collaboration containers and notifications without reusing the same activity logging path.
+- The Control Center Activity Logs tab only knew the older activity types, so `chat_activity` rows could not be filtered directly and fell back to `N/A` details even when the records existed in Cosmos.

+
+Code changes summary:
+
+- Updated `log_chat_activity(...)` to persist a `chat_activity` record to the `activity_logs` Cosmos container and keep emitting App Insights telemetry.
+- Added workspace and source context fields so standard chat, document-action chat, and collaboration chat records can be filtered consistently later.
+- Wired the document analysis/compare request path to call the shared chat activity helper immediately after the user message is saved.
+- Wired collaborative multi-user message persistence to call the same shared helper for saved user messages.
+- Extended the Control Center Activity Logs search path, filter dropdown, and row formatter so `chat_activity` records can be surfaced and identified as document-action or multi-user chat activity.
+- Kept existing personal SimpleChat message logging aligned with the expanded helper signature.
+
+Testing approach:
+
+- Added a focused regression test covering shared helper persistence, collaboration message logging, and document-action route wiring.
+- Added a UI regression test for the Control Center Activity Logs tab that verifies the `chat_activity` filter and chat activity row rendering.
+- Recompiled the touched Python files with `py_compile` after the code change.
+
+## Validation
+
+Before:
+
+- Analyze and compare user messages were not routed through the shared chat activity logger.
+- Multi-user collaboration user messages were not creating matching chat activity records.
+- Standard chat activity could not be surfaced from `activity_logs` because it only existed in telemetry.
+
+After:
+
+- Standard chat messages now create `chat_activity` records in `activity_logs` and continue emitting telemetry.
+- Analyze and compare messages now use the same shared logger right after the user message is persisted.
+- Collaboration user messages now use the same shared logger after collaborative persistence succeeds.
+- Control Center Activity Logs now exposes `chat_activity` directly and renders document-action or collaboration message context instead of generic `N/A` details.

+# Chat Capability Usage Metadata Fix (v0.241.123)
+
+Fixed in version: **0.241.123**
+
+## Issue Description
+
+Chat metadata made document and web grounding visible only indirectly. User messages stored some button states, but Deep Research was not shown in the drawer, and assistant responses required readers to infer Web Search or Deep Research usage from website citations or source-review payloads.
+
+## Root Cause Analysis
+
+- Standard and streaming chat responses persisted citations and compact Deep Research details, but did not persist a shared explicit capability usage block.
+- Analyze and Compare document-action messages had action-specific metadata, but did not expose the same Search / Analyze / Compare usage shape as standard workspace search messages.
+- The metadata drawer showed Web Search button state for user messages and web citation counts for assistant messages, but did not render explicit Web Search used or Deep Research used fields.
+
+## Technical Details
+
+### Files Modified
+
+- `application/single_app/route_backend_chats.py`
+- `application/single_app/static/js/chat/chat-messages.js`
+- `application/single_app/config.py`
+- `functional_tests/test_chat_capability_usage_metadata.py`
+- `ui_tests/test_chat_capability_metadata_drawer.py`
+
+### Code Changes Summary
+
+- Added a shared `capability_usage` metadata object for user and assistant messages.
+- Tracked workspace action usage as `search`, `analyze`, or `compare` across standard chat, streaming chat, and document-action chat paths.
+- Added explicit Web Search and Deep Research enabled/used fields to assistant response metadata.
+- Updated the metadata drawer to show URL Access, Deep Research, and capability usage labels directly.
+- Updated `config.py` from `0.241.122` to `0.241.123` for traceability.
+
+### Testing Approach
+
+- Added a functional regression that validates the helper output for Search, Analyze, Compare, Web Search, and Deep Research metadata.
+- Added a Playwright UI regression that mocks message metadata payloads and verifies the drawer displays explicit capability usage labels.
+
+## Validation
+
+### Test Results
+
+- `python functional_tests/test_chat_capability_usage_metadata.py`
+- `python -m py_compile application/single_app/route_backend_chats.py functional_tests/test_chat_capability_usage_metadata.py`
+- `node --check application/single_app/static/js/chat/chat-messages.js`
+
+### Before / After
+
+- Before: assistant metadata showed web citations but did not clearly state that Web Search or Deep Research was used.
+- After: both user and assistant metadata include `capability_usage.web_search` and `capability_usage.deep_research` with explicit `enabled` and `used` values.
+- Before: Analyze and Compare metadata was action-specific but not normalized with Search metadata.
+- After: `capability_usage.actions` consistently records `search`, `analyze`, and `compare` usage.
+
+### User Experience Improvements
+
+- Users and admins can inspect a message and see exactly whether a response used workspace search, Analyze, Compare, Web Search, URL Access, or Deep Research.
+- Web citations remain available, but they are no longer the only signal that a response used web grounding.

+# Chat Document Action Scope Authorization Fix
+
+Fixed in version: **0.241.209**
+
+## Issue Description
+
+Chat document actions could carry caller-provided group or public workspace scope ids into document analysis and comparison flows after basic action normalization. Normal chat Search already filtered these ids through the authorized chat scope context, but the document-action path had a separate execution route and did not apply the same boundary before invoking the workflow runner.
+
+## Root Cause Analysis
+
+The document-action route trusted normalized `active_group_ids` and `active_public_workspace_id` values as execution inputs. The workflow search/document context helpers also accepted explicit group and public workspace ids without intersecting them with the current user's access. A related tabular evidence helper could build a related-document catalog from invocation-supplied group or public workspace ids before evidence lookup.
+
+## Technical Details
+
+Files modified:
+
+- `application/single_app/route_backend_chats.py`
+- `application/single_app/functions_search_service.py`
+- `application/single_app/config.py`
+- `functional_tests/test_chat_upload_personal_workspace_handoff.py`
+
+Code changes:
+
+- Document actions now revalidate requested group and public workspace ids with `_get_authorized_chat_scope_context()` before analysis or comparison execution.
+- Unauthorized document-action scopes return a 403 response instead of being passed to the workflow runner.
+- Document-action selected document metadata now resolves through `_resolve_chat_selected_document_metadata()` so display names use the same scoped lookup model as normal chat search metadata.
+- Shared search-service helpers now intersect explicit group ids with the user's current group memberships and public workspace ids with the user's visible public workspace ids.
+- Tabular related-document evidence augmentation now refuses group/public ids that are not present in the request's authorized chat context before building related-document catalogs.
+
+## Testing Approach
+
+Functional test coverage was extended in `functional_tests/test_chat_upload_personal_workspace_handoff.py` with source-contract assertions for:
+
+- Document-action scope revalidation.
+- 403 rejection of unauthorized group/public workspace ids.
+- Safe selected-document metadata resolution.
+- Shared search-service group/public scope filtering.
+- Authorized tabular related-document scope handling.
+
+## Impact Analysis
+
+This closes a route-level access-control gap for Analyze and Compare without changing the intended behavior for authorized personal, group, public, assigned-knowledge, or uploaded task document flows. Users can still analyze documents they are allowed to access, but cannot cause the chat backend to search or analyze another group's or hidden public workspace's documents by supplying ids directly.
+
+## Validation
+
+Before this fix, document-action scope ids were trusted after normalization. After this fix, document-action and shared search-service paths revalidate group/public ids at the server boundary and at the shared document context layer.
+
+Related version update: `application/single_app/config.py` was updated to **0.241.209**.

+# Chat Dropdown Responsive Width Fix
+
+Fixed in version: **0.242.017**
+
+## Issue Description
+
+The chat pane workspace scope, tags, and document dropdown menus were capped to narrow trigger widths. Long workspace names, tag labels, and document titles were truncated too aggressively, especially when users opened the grounded search controls from the compact chat toolbar.
+
+## Root Cause Analysis
+
+The dropdown menu width was controlled in several places at once: inline template styles, fixed CSS max-width rules, and JavaScript runtime sizing that set each popup menu `maxWidth` to the trigger field width. Because the same controls are reused in the mobile grounded-search drawer, the behavior affected desktop and mobile layouts.
+
+## Technical Details
+
+Files modified:
+
+- `application/single_app/templates/chats.html`
+- `application/single_app/static/css/chats.css`
+- `application/single_app/static/js/chat/chat-documents.js`
+- `ui_tests/test_chat_search_panel_mobile_drawer.py`
+- `functional_tests/test_chat_searchable_selectors.py`
+- `application/single_app/config.py`
+
+Code changes summary:
+
+- Replaced inline dropdown menu widths with a shared `chat-search-filter-menu` class.
+- Updated the shared search-filter dropdown sizing helper to use viewport-aware desktop bounds and full drawer-width mobile sizing.
+- Configured the document dropdown to open upward on desktop and downward in the mobile grounded-search drawer using Popper placement instead of CSS-forced positioning.
+- Refreshed Bootstrap dropdown placement after responsive sizing so the desktop document menu remains visible above the composer.
+- Added label overflow rules so long item text truncates inside the expanded popup instead of forcing viewport overflow.
+
+## Testing Approach
+
+- Extended the Playwright chat grounded-search drawer test to validate dropdown bounds in both desktop and mobile viewports.
+- Extended the chat searchable selector functional test to verify the responsive sizing helper and prevent the old `maxWidth = containerWidth` cap from returning.
+
+## Impact Analysis
+
+Desktop dropdown menus can now grow beyond narrow trigger fields while staying within the viewport. The document dropdown opens upward from the desktop composer through Bootstrap/Popper placement so it remains interactive above the message box. Mobile dropdowns remain constrained to the grounded-search drawer width and open downward inside that drawer, so the change improves readability without causing offcanvas overflow.
+
+## Validation
+
+Before the fix, scope, tags, and document menus could be hard capped to widths like 250px or the narrow trigger field width. After the fix, desktop menus use a wider responsive popup and mobile menus stay aligned to the drawer fields.
+

+# Chat File Upload Client Flag Fix
+
+Fixed in version: **0.241.110**
+
+## Issue Description
+
+Chat file uploads could be enabled in Admin Settings, but users still saw `Chat file uploads are not enabled for your account.` when selecting, pasting, or dropping a file in chat.
+
+## Root Cause Analysis
+
+The `/chats` route calculated the effective per-user `enable_chat_file_uploads` value, including the optional `ChatFileUploadUser` role requirement, but the chat template did not serialize that value into `window.appSettings`. The chat upload JavaScript checked `window.appSettings.enable_chat_file_uploads`, so the missing property evaluated to `false` and blocked uploads before the browser posted to `/upload`.
+
+## Technical Details
+

+- `docs/explanation/features/CHAT_FILE_UPLOAD_ACCESS_CONTROL.md`
+
+Code changes summary:
+- Added `enable_chat_file_uploads` to the chat page `window.appSettings` object using the effective server-rendered setting.
+- Wrapped the chat file input and paperclip controls in the effective setting so users without chat upload permission do not see unavailable controls.
+- Updated functional coverage to assert the client upload gate receives the effective setting.
+
+Related config.py version update: `application/single_app/config.py` was incremented to `0.241.110`.

+Before the fix, the JavaScript upload guard treated the missing app setting as disabled. After the fix, chat upload controls and selected, pasted, or dropped uploads use the same effective setting produced by the backend.

+# Chat Inline Chart Export PNG Fix
+
+Fixed/Implemented in version: **0.241.136**
+
+## Issue Description
+
+Inline `simplechart` blocks rendered correctly inside chat, but per-message export paths could preserve the raw chart code instead of exporting a chart image. This affected exports to Word, PowerPoint, and email drafts when the model produced a YAML-style chart block rather than strict JSON.
+
+## Root Cause Analysis
+
+The browser chart renderer accepted both JSON and loose YAML-style `simplechart` payloads. The server export helper only parsed strict JSON before rendering charts to PNG data URIs. When parsing failed, export output kept the original fenced code block.
+
+## Technical Details
+
+### Files Modified
+
+- `application/single_app/functions_chart_export.py`
+- `application/single_app/config.py`
+- `functional_tests/test_conversation_export_inline_chart_images.py`
+
+### Code Changes Summary
+
+- Added server-side loose `simplechart` parsing for model-authored YAML-style chart blocks.
+- Normalized chart specs before rendering so JSON and YAML-style payloads follow the same export path.
+- Preserved existing PNG data URI generation used by Markdown/PDF, Word, PowerPoint, and email draft exports.
+- Bumped `config.py` version to `0.241.136`.
+
+### Testing Approach
+
+- Extended functional export tests to validate YAML-style charts are converted to PNG data URIs.
+- Added Word export coverage to confirm YAML-style charts are embedded as DOCX media.
+- Added PowerPoint appendix asset coverage to confirm converted charts are extractable as PNG images.
+
+## Impact Analysis
+
+Chat rendering behavior is unchanged. Export paths now handle the same chart block format already supported in the chat UI, reducing the chance that model-generated chart code appears in exported artifacts.

+# Chat Inline Chart Final Canvas Fix
+
+Fixed in version: **0.241.134**
+
+## Issue Description
+
+Inline `simplechart` responses could render correctly while the assistant response was streaming, then become a blank chart area after streaming completed and the final saved message replaced the temporary streaming message.
+
+## Root Cause Analysis
+
+Final assistant messages apply message metadata through the masking state pipeline. That pipeline captured original message content after Chart.js had hydrated the chart, then restored cloned DOM nodes. Cloned canvas elements keep attributes such as `data-chart-hydrated="true"`, but they do not keep the rendered canvas pixels or the Chart.js instance. The final DOM therefore looked hydrated while the canvas was blank.
+
+## Technical Details
+
+Files modified:
+

+- `functional_tests/test_chat_backend_inline_chart_handoff.py`
+- `ui_tests/test_chat_inline_chart_rendering.py`
+
+Code changes:
+
+- Added inline chart destruction/rehydration handling so restored message content cannot retain stale Chart.js state.
+- Moved chart hydration to run after message masking metadata restores original content.
+- Made chart hydration repair chart containers that are marked hydrated but have no live Chart.js instance.
+- Added UI regression coverage for final assistant messages that include metadata.
+- Updated `config.py` to version `0.241.134`.
+
+## Validation
+
+Test coverage:

+
+Validation performed:
+
+- JavaScript syntax checks passed for the chart renderer and chat message renderer.
+- Python compile checks passed for the updated tests and config.
+- Backend inline chart handoff functional test passed.
+- Manual authenticated chat validation used the model-generated prompt `make a pie chart 33% apples, 33% oranges, and 34% pears`; after streaming completed, the final chart had a live Chart.js instance and nonblank canvas pixels.

+# Chat Inline Chart YAML Streaming Fix
+
+Fixed in version: **0.241.126**
+
+## Issue Description
+
+Normal chat chart responses could display raw `simplechart` source text instead of an inline chart card when the assistant emitted a YAML-style chart block. During streaming, incomplete chart fences were also rendered as visible text before the chart block finished.
+
+## Root Cause Analysis
+
+The inline chart renderer only parsed JSON payloads inside `simplechart` fenced blocks. If the assistant emitted a YAML-like block such as `chartType: pie`, parsing failed and the markdown renderer treated the block as ordinary code. Incomplete streaming fences were not hidden because the chart extractor only matched closed fences.
+
+## Technical Details
+
+Files modified:
+
+- `application/single_app/static/js/chat/chat-inline-charts.js`
+- `application/single_app/config.py`
+- `ui_tests/test_chat_inline_chart_rendering.py`
+
+Code changes:
+
+- Added a constrained YAML-like parser for the chart block shape produced by chat responses.
+- Normalized generic `kind: chart` values through `chartType` so `chartType: pie` renders correctly.
+- Honored Chart.js-style legend options under `options.plugins.legend`.
+- Replaced incomplete `simplechart` fences with a chart status card so raw chart source is not visible during streaming.
+- Added UI coverage for completed YAML-style charts and pending chart blocks.
+
+## Validation
+
+Test coverage:
+
+- `ui_tests/test_chat_inline_chart_rendering.py`
+
+Expected behavior:
+
+- Users see a chart card instead of YAML chart text when a completed chart block is present.
+- Users see a pending chart card, not raw chart source, while a chart block is still streaming.
+- Completed chart messages still render correctly after the stream finishes or the message is reloaded.

+# Chat Inline Export Action Persistence Fix
+
+## Header Information
+
+Version implemented: **0.241.108**
+
+Issue description:
+
+Inline assistant export buttons were visible when the response first arrived, but they disappeared after leaving the conversation and returning later.
+
+Root cause analysis:
+
+The inline action renderer only created the buttons when `appendMessage(...)` was called with `isNewMessage = true`. Conversation history always reloads with `isNewMessage = false`, so the same assistant reply lost its inline actions even when the immediately preceding user request still clearly asked for Word, PowerPoint, Markdown, or email output.
+
+Related config update: `application/single_app/config.py` now sets `VERSION = "0.241.108"`.
+
+## Technical Details

+
+- `application/single_app/static/js/chat/chat-messages.js`
+- `application/single_app/config.py`
+- `ui_tests/test_chat_inline_export_action_buttons.py`
+
+Code changes summary:
+
+- Replaced the strict `isNewMessage` gate with a check against the most recently rendered chat message.
+- Inline export buttons now render for assistant replies when they directly follow a qualifying user prompt, even during history reload.
+- Kept the progress-label behavior for inline actions so reload persistence and in-progress button text share the same listener path.
+
+Testing approach:
+
+- Updated the focused Playwright regression to cover a history-loaded assistant reply with `isNewMessage = false`.
+- Re-ran JavaScript syntax validation for `chat-messages.js`.
+
+## Validation
+
+Before:
+
+- A qualifying assistant response showed inline export buttons only on first render.
+- Returning to the same conversation removed the inline export actions because history messages never met the `isNewMessage` condition.
+
+After:
+
+- Returning to a conversation preserves inline export buttons for assistant replies that still directly follow a qualifying user request.
+- Non-qualifying assistant replies still stay clean and do not gain inline export actions.

+# Chat Messages Artifact Render Syntax Fix
+
+Fixed in version: **0.241.129**
+
+## Issue Description
+
+Opening Chats could fail during page load with a JavaScript parse error in `chat-messages.js`, which prevented the chat message module from initializing.
+
+## Root Cause
+
+Generated artifact helper functions were accidentally inserted inside the `carouselButtonsHtml` template literal inside `appendMessage(...)`. That broke the surrounding footer assembly, cut off the citation setup, and left the browser parser reading stray `Generated ...` template text as code.

+
+Code changes summary:
+
+- Restored the AI message footer template so the carousel buttons, action buttons, and citation HTML are assembled as valid JavaScript again.
+- Moved the generated analysis artifact hydration helpers back to function scope.
+- Switched AI message rendering to hydrate all generated analysis artifacts instead of only the legacy tabular subset.
+- Tightened the existing chat artifact UI regression test so page-level JavaScript errors fail the scenario.
+
+Testing approach:
+
+- `node --check application/single_app/static/js/chat/chat-messages.js`
+- `pytest ui_tests/test_chat_generated_tabular_output_card.py`
+
+## Validation

+- Visiting Chats raised `Uncaught SyntaxError: Unexpected identifier 'Generated'` from `chat-messages.js`.
+- Chat message rendering could stop before footer actions and generated artifact cards initialized.
+
+After:
+
+- `chat-messages.js` parses cleanly.
+- Chats can initialize the AI message renderer again.
+- The generated artifact card regression test now also guards against page parse errors.

+The model and agent selectors use fixed Popper positioning so their menus can escape toolbar clipping. The shared searchable-select CSS set `min-width: 100%`, which is safe for normal absolute dropdowns but resolves against the viewport for fixed-positioned menus before Popper calculates placement. Popper measured the menu as viewport-wide, then clamped it to the left padding to prevent overflow.

+Files modified:
+- `application/single_app/static/css/chats.css`
+- `application/single_app/config.py`
+- `ui_tests/test_chat_model_dropdown_width.py`
+
+Code changes summary:
+- Added a specific CSS min-width override for the fixed-position model and agent searchable menus so Popper measures a compact menu before applying placement.
+- Expanded the existing chat model dropdown UI regression test to assert horizontal anchoring, not just compact width.
+- Added agent dropdown coverage that verifies the menu remains compact and overlaps its trigger button.
+- Updated `config.py` to version `0.241.126` for traceability.
+
+Testing approach:
+- Updated Playwright UI coverage in `ui_tests/test_chat_model_dropdown_width.py` to validate model and agent dropdown width, viewport fit, and horizontal anchoring.
+
+## Validation
+
+Expected behavior after the fix:
+- The model dropdown opens aligned with the model selector.
+- The agent dropdown opens aligned with the agent selector.
+- Both menus stay compact and do not span or align to the browser's left edge.
+- The shared prompt dropdown behavior remains unchanged.

+# Chat Model Dropdown Width Fix
+
+Fixed/Implemented in version: **0.241.036**
+
+## Issue Description
+
+The chat model selection dropdown could expand across the full browser window when opened. This made the searchable model picker feel disconnected from the compact toolbar selector and inconsistent with the prompt and document dropdowns.
+
+## Root Cause Analysis
+
+The model selector uses fixed Popper positioning so it can escape toolbar clipping. The shared searchable-select CSS used `min-width: 100%`, which is safe for normal absolute dropdowns but resolves against the viewport for fixed-positioned menus. That made the model dropdown's minimum width the full window width.
+
+## Technical Details
+
+Files modified:
+- `application/single_app/static/js/chat/chat-searchable-select.js`
+- `application/single_app/static/js/chat/chat-model-selector.js`
+- `application/single_app/static/js/chat/chat-agents.js`
+- `application/single_app/config.py`
+- `ui_tests/test_chat_model_dropdown_width.py`
+
+Code changes summary:
+- Added a reusable floating searchable-select dropdown config that sets the menu minimum width from the toggle button's measured width in pixels.
+- Reused that config for model and agent selectors so both fixed-position toolbar dropdowns stay compact.
+- Updated `config.py` from version `0.241.035` to `0.241.036` for traceability.
+
+Testing approach:
+- Added a Playwright UI regression test that opens the chat model dropdown and verifies the menu remains bounded to the compact selector instead of spanning the viewport.
+
+## Validation
+
+Expected behavior after the fix:
+- The model dropdown opens near the model selector and stays within a compact width.
+- The model search input stays inside the dropdown menu.
+- The shared prompt dropdown behavior remains unchanged.
+- The agent dropdown uses the same bounded floating behavior as the model dropdown.

+# Chat New Conversation Action State Reset Fix
+
+Fixed in version: **0.241.106**
+
+## Issue Description
+
+Starting a new chat did not consistently clear per-chat toolbar actions. Web Search and some other toolbar surfaces could remain visibly selected after clicking New Chat, while URL Access and Deep Research were already reset through a conversation context-change listener.
+
+## Root Cause Analysis
+
+The New Chat flow dispatched `chat:conversation-context-changed`, but only `chat-input-actions.js` listened to that event, and its reset only covered URL Access and Deep Research. Workspace search, prompt selection, Web Search, image generation, and pending file state were owned by separate modules or code paths and did not share a consistent reset contract.
+
+## Version Implemented
+
+Implemented in version: **0.241.106**
+
+The application version was updated in `application/single_app/config.py` from `0.241.105` to `0.241.106` for this fix.
+
+## Technical Details
+
+Files modified:
+
+- `application/single_app/static/js/chat/chat-input-actions.js`
+- `application/single_app/static/js/chat/chat-documents.js`
+- `application/single_app/static/js/chat/chat-prompts.js`

+- `ui_tests/test_chat_deep_research_toggle.py`
+- `ui_tests/test_chat_new_conversation_tag_reset.py`
+
+Code changes summary:
+
+- Added a consistent conversation context reset for per-chat input actions: Web Search, URL Access, visible Deep Research state, image generation, and pending file selection.
+- Added a workspace reset listener that hides the Workspaces panel, clears selected document/tag/action state, and keeps auto-created conversations able to preserve selections through `preserveSelections`.
+- Added a prompt reset listener so the prompt picker does not stay open across explicit New Chat.
+- Added a saved `deepResearchDefaultEnabled` preference so Deep Research can be restored when Web Search is opened or direct URLs are present, without programmatic New Chat resets overwriting that preference.
+- Switched the Web Search notice container to Bootstrap `d-none` visibility so reset behavior is class-based.
+
+## Testing Approach
+
+- Added `functional_tests/test_chat_new_conversation_action_state_reset.py` to statically verify the reset listeners, Deep Research default preference, Web Search notice visibility, and version update.
+- Updated `ui_tests/test_chat_deep_research_toggle.py` to verify saved Deep Research defaults reapply for Web Search and direct URL prompts while stubbing user settings persistence.
+- Updated `ui_tests/test_chat_new_conversation_tag_reset.py` to verify explicit New Chat clears Workspaces and Web Search action state in addition to selected tags.
+
+## Impact Analysis
+
+Explicit New Chat now starts from a clean per-chat toolbar state. Auto-created conversations from typing, sending, prompt use, or file upload continue to preserve current selections through the existing `preserveSelections` path. Deep Research remains user-friendly for repeat use because the remembered preference survives resets and can reapply when the relevant source action becomes available.
+
+## Validation
+
+Expected after validation:
+
+- `node --check application/single_app/static/js/chat/chat-input-actions.js`
+- `node --check application/single_app/static/js/chat/chat-documents.js`
+- `node --check application/single_app/static/js/chat/chat-prompts.js`
+- `python functional_tests/test_chat_new_conversation_action_state_reset.py`
+- `python functional_tests/test_chat_preserves_workspace_selection_on_auto_create.py`
+- Focused UI tests where environment variables are configured.

+# Chat Paste and Drag-and-Drop Upload Fix
+
+Fixed/Implemented in version: **0.241.056**
+
+## Issue Description
+
+Chat supported pasted clipboard images, but a later plain-text paste could still be interpreted as an image upload when the clipboard event contained stale nameless image data. Chat also lacked direct drag-and-drop upload support in the message input area.
+
+## Root Cause Analysis
+
+The chat paste handler treated any file-like clipboard item as an upload and prevented the browser's default paste behavior. Some clipboard sources can expose both text and stale nameless image data, so the handler needed to prefer real text paste unless the clipboard file has an explicit filename.
+
+## Technical Details
+
+Files modified:
+- `application/single_app/static/js/chat/chat-input-actions.js`
+- `application/single_app/templates/chats.html`
+- `application/single_app/config.py`
+- `functional_tests/test_chat_clipboard_paste_upload_support.py`
+- `ui_tests/test_chat_clipboard_paste_upload_workflow.py`
+
+Code changes summary:
+- Added a plain-text guard for clipboard uploads so normal text paste is not blocked by stale nameless image files.
+- Preserved paste uploads for nameless screenshots/images when no text is present and for named files copied from file managers.
+- Added drag-and-drop file uploads on the chat input area using the same chat upload helper and user agreement flow.
+- Added a lightweight drag-active visual state for the chat input.
+
+Related version update: `application/single_app/config.py` was incremented from `0.241.055` to `0.241.056`.
+
+## Validation
+
+Testing approach:
+- Functional coverage checks the shared upload helper, text-paste guard, drag-and-drop binding, and version marker.
+- UI coverage simulates a pasted clipboard image, a subsequent text paste with stale image data, and a dropped text file upload.
+
+Expected behavior after the fix:
+- Pasted screenshots/images upload into the current chat.
+- Pasted text remains text, even after a prior image paste.
+- Dropped files upload into the current chat through the existing upload flow.

+# Chat Search Panel Document Row Fix
+
+Fixed/Implemented in version: **0.241.030**
+
+## Issue Description
+
+The chat grounded-search panel allowed the Document picker to wrap onto a second row for Search and Analyze on constrained desktop widths. Compare did not show the same visual issue, which made the action layouts feel inconsistent.
+
+## Root Cause Analysis
+
+The filter strip used a wrapping flex row. The Document picker had a large flex basis, so the browser made the wrap decision before the field could shrink into the available remaining space.
+
+## Technical Details
+
+Files modified:
+- `application/single_app/static/css/chats.css`
+- `application/single_app/config.py`
+- `ui_tests/test_chat_search_panel_document_row_layout.py`
+
+Code changes summary:
+- Changed the desktop grounded-search filter strip to a four-column grid with bounded Action, Scope, and Tags columns plus a flexible Document column.
+- Preserved the existing mobile drawer behavior, where the controls stack in a single column.
+- Updated `config.py` from version `0.241.029` to `0.241.030` for traceability.
+
+Testing approach:
+- Added a Playwright UI regression test that validates Search and Analyze keep the Document picker on the same row at a constrained desktop width.
+- Added mobile validation to ensure the Document picker still stacks below Tags without page-level horizontal overflow.
+
+## Validation
+
+Expected behavior after the fix:
+- Search, Analyze, and Compare use a consistent single-row desktop layout for Action, Scope, Tags, and Document.
+- Mobile and smaller canvas layouts continue to stack controls inside the drawer.
+- The Document button fills its field and does not introduce horizontal scrolling.

+# Chat Sidebar Escape HTML Import Fix
+
+Fixed in version: **0.242.051**
+
+## Issue Description
+
+Opening Chats could fail while loading the sidebar conversation list with `ReferenceError: escapeHtml is not defined` from `chat-sidebar-conversations.js`. When this happened, conversation rendering stopped and URL-selected conversations could fail to load.
+
+## Root Cause
+
+`chat-sidebar-conversations.js` was loaded as a JavaScript module and called `escapeHtml(...)` while relying on a helper that was not in that module scope. Browser modules do not expose top-level helpers from sibling modules unless they are explicitly imported.
+
+## Technical Details
+
+Files modified:
+
+- `application/single_app/static/js/chat/chat-sidebar-conversations.js`
+- `application/single_app/config.py`
+- `functional_tests/test_chat_sidebar_conversations_escape_html.py`
+
+Code changes summary:
+
+- Imported the shared `escapeHtml` helper from `chat-utils.js` into the sidebar conversations module.
+- Replaced the sidebar error message HTML assignment with DOM construction and `textContent`.
+- Replaced the selection-mode indicator icon `innerHTML` assignment with DOM construction.
+- Added a focused functional regression test for the import and XSS guardrail coverage.

+
+The chat sidebar conversation list can render escaped conversation titles again, and the touched sidebar paths avoid dynamic HTML sinks for error and icon rendering.

+# Chat Streaming SSE And Metadata Fix
+
+Fixed in version: **0.241.049**
+
+## Issue Description
+
+Streaming assistant responses could fail partway through rendering with `Error parsing SSE data` in `chat-streaming.js`, and temporary AI placeholder renders produced noisy `No metadata found for AI message` console entries. In the same streaming path, the final assistant message was rebuilt without the message metadata already written on the backend.
+
+## Root Cause Analysis
+
+- One agent-streaming branch in `route_backend_chats.py` emitted the literal characters `\n\n` instead of real SSE frame delimiters, which caused multiple JSON payloads to be concatenated inside one client parse block.
+- `finalizeStreamingMessage` rebuilt the final message with `fullMessageObject = null`, so metadata stored in the backend assistant document was discarded during the final client render.
+- `appendMessage` logged missing metadata for every temporary AI placeholder, which turned a normal temporary render into misleading console noise.
+
+## Version Implemented
+
+- **0.241.049**
+
+## Files Modified
+
+- `application/single_app/route_backend_chats.py`
+- `application/single_app/static/js/chat/chat-streaming.js`
+- `application/single_app/static/js/chat/chat-messages.js`
+- `functional_tests/test_chat_streaming_sse_metadata_fix.py`
+
+## Code Changes Summary
+
+- Corrected the agent-streaming SSE chunk emitter to use real `\n\n` separators.
+- Added a defensive client-side normalizer in `chat-streaming.js` so malformed legacy escaped SSE delimiters do not break the parser if encountered.
+- Included backend message metadata in final streaming payloads and passed the completed payload back into `appendMessage` as the final `fullMessageObject`.
+- Removed the AI-side missing-metadata console noise for temporary placeholder messages.
+
+## Testing Approach
+
+- Added `functional_tests/test_chat_streaming_sse_metadata_fix.py` to validate the corrected SSE emitter contract, final metadata handoff, and removal of noisy AI metadata logging.
+- Ran the new functional test locally in the repository virtual environment.
+
+## Impact Analysis
+
+- Streaming agent responses no longer corrupt the SSE parser when the agent chunk branch is used.
+- Final streamed assistant messages preserve backend metadata for masking and other client-side metadata consumers.
+- Browser console output is quieter and no longer reports a false metadata problem for temporary AI placeholders.
+
+## Validation
+
+- Before: agent streaming could log `Unexpected non-whitespace character after JSON` and final streamed AI messages lost metadata during re-render.
+- After: streamed chunks are frame-delimited correctly, final message metadata is preserved, and temporary placeholder renders no longer emit the misleading AI metadata log.

+# Chat Upload Assigned Knowledge User Context Fix
+
+Version: 0.241.200
+
+Fixed/Implemented in version: **0.241.200**
+
+Related config.py update: `VERSION = "0.241.200"`
+
+## Header Information
+
+- Issue description: Workspace-backed files uploaded in chat could appear as added file messages, but an Assigned Knowledge agent that allowed user workspace context did not always search those uploaded documents on the next prompt.
+- Root cause analysis: The chat upload completion watcher only selected the workspace document after processing completed, and the request payload depended on a separate user workspace context toggle. In locked Assigned Knowledge conversations, the backend could still apply the agent's public workspace filters and leave `assigned_knowledge_user_context_active` false, so the linked personal workspace upload was omitted even though the agent policy allowed user task context. After enabling the backend user-context merge, the final search merge still sliced the combined result list back to the assigned corpus top-N, which could drop all personal/group upload chunks.
+- Version implemented: 0.241.200
+
+## Technical Details
+
+- Files modified: `application/single_app/route_backend_chats.py`, `application/single_app/static/js/chat/chat-documents.js`, `application/single_app/static/js/chat/chat-messages.js`, `application/single_app/static/js/chat/chat-input-actions.js`, `application/single_app/config.py`, `functional_tests/test_chat_upload_personal_workspace_handoff.py`, `ui_tests/test_chat_workspace_upload_progress_polling.py`.
+- Code changes summary: Added a chat-upload activation helper for user workspace context, generalized chat-upload document selection across personal and group workspace scopes, passed workspace scope/group id through the upload watcher, hardened the backend merge so search-ready conversation-linked chat uploads activate Assigned Knowledge user context when the agent allows workspace search, and changed Assigned Knowledge search merging to keep the assigned corpus cap while appending all deduplicated personal/group user-context hits.
+- Testing approach: Updated functional contract tests for the upload handoff, backend Assigned Knowledge merge activation, and the user-context result preservation behavior, plus UI polling test coverage to validate immediate context activation and scope-aware watcher behavior.
+- Impact analysis: Agents with Assigned Knowledge and creator-approved user workspace context now include workspace-backed chat uploads as task context as soon as the upload is queued. The assigned corpus remains capped normally, while personal/group task-context chunks are preserved even when the combined citation count exceeds the usual top-N limit.
+
+## Validation
+
+- Test results: `functional_tests/test_chat_upload_personal_workspace_handoff.py` validates the updated upload-to-workspace contract, and `ui_tests/test_chat_workspace_upload_progress_polling.py` validates the browser watcher behavior.
+- Before/after comparison: Before the fix, the uploaded document could be present in the conversation but omitted from the next agent request when Assigned Knowledge locked the effective search scope to public, or searched but dropped when assigned public results filled the top-N window. After the fix, the workspace-backed upload immediately enables user workspace context on the client, the backend auto-merges ready linked uploads as user task context when the agent policy allows it, and personal/group user-context chunks are appended after assigned results instead of being sliced away.
+- User experience improvements: Users can upload a file in chat and immediately ask an Assigned Knowledge agent about it when that agent permits user workspace task context.

+- Issue description: Assigned Knowledge conversations could ignore a document uploaded at the start of the chat, especially when the user selected Analyze before the workspace picker could select the processed upload.
+- Root cause analysis: The existing upload merge was tied to normal search context and frontend scope selection. Analyze validated selected document IDs before resolving conversation-linked uploads, and the scope lock could prevent the uploaded personal document from appearing in the selected workspace scope even though the agent policy allowed user task documents.

+- Code changes summary: Added an action-aware conversation task document resolver for search-ready chat uploads, used it for normal Search and Analyze policy checks, auto-filled Analyze targets from ready linked uploads before document-action validation, and added frontend task-document state that survives scope lock and message reloads.
+- Testing approach: Updated source-contract functional coverage for the backend resolver, assigned-knowledge policy gates, Analyze autofill, frontend task-document payloads, and pending/denied Analyze warnings; updated the upload polling UI test to validate completed uploads register as task documents.

After the fix, ready conversation-linked uploads are resolved on the backend and can satisfy Analyze without unlocking the whole personal workspace.
+- User experience improvements: Users can upload a task document to an Assigned Knowledge chat and ask for Search or Analyze behavior as long as the agent policy allows that action, with clearer warnings when the upload is still processing or the agent disallows uploaded task documents.

+# Chat Upload Personal Workspace Isolation Fix (v0.241.208)
+
+Version: 0.241.208
+
+Fixed/Implemented in version: **0.241.208**
+
+Related config.py version update: `application/single_app/config.py` now sets `VERSION = "0.241.208"`.
+
+## Issue Description
+
+The assigned-knowledge task context split introduced a risky route-level search shape for upload-first agent chats. When a public/global agent had public assigned knowledge and the user uploaded a personal task document, the route could merge assigned public document IDs with the uploaded task document IDs and activate a broad user-context search.
+
+## Root Cause Analysis
+
+- Assigned knowledge document IDs and user task document IDs were temporarily combined before normal Search built its search arguments.
+- Auto-linked uploads could produce an `all`-scope user-context search instead of a narrow current-user personal task-document search.
+- The assigned/user-context merge accepted personal-looking results without requiring the result `user_id` to match the current user.
+
+## Technical Details
+
+### Files Modified
+
+- `application/single_app/route_backend_chats.py`
+- `application/single_app/config.py`
+- `functional_tests/test_chat_upload_personal_workspace_handoff.py`
+
+### Code Changes Summary
+
+- Kept assigned knowledge document IDs out of the auto-linked upload task-document merge.
+- Preserved assigned knowledge as a separate top-12 reference search.
+- Disabled shared personal document expansion for auto-linked upload Search paths.
+- Required appended personal user-context search results to have `user_id` matching the current user.
+- Applied the same isolation in normal and streaming chat Search.
+
+### Testing Approach
+
+- Extended the chat upload handoff functional source-contract test with assertions for task/assigned ID separation, current-user personal-result filtering, and shared personal search disabling.
+
+## Impact Analysis
+
+- Public/global agents can still use public assigned knowledge as reference context.
+- Uploaded personal task documents remain usable for Search and Analyze.
+- Auto-linked upload Search can no longer broaden into other users' personal workspace documents.

+# Chat User Setting Partial Save Fix
+
+Fixed in version: **0.242.051**
+
+## Issue Description
+
+The Chats page could log `Failed to save user setting: HTTP error! status: 404` after changing a model or other chat preference, even when `/api/user/settings` was available and earlier settings loads succeeded.
+
+## Root Cause
+
+The chat `saveUserSetting(...)` helper fetched the full current settings document, merged one changed key in the browser, and posted the full settings object back to `/api/user/settings`. If the existing settings included a stale `activeGroupOid` or `activePublicWorkspaceOid`, the backend could reject the entire save while processing that unrelated stale value.
+
+## Technical Details
+
+Files modified:
+
+- `application/single_app/static/js/chat/chat-layout.js`
+- `application/single_app/route_backend_users.py`
+- `application/single_app/config.py`
+- `functional_tests/test_chat_user_setting_partial_save.py`
+- `functional_tests/test_user_settings_allowlist_keys.py`
+
+Code changes summary:
+
+- Changed `saveUserSetting(...)` to POST only the requested partial settings update.
+- Kept server-side merging in `update_user_settings(...)` as the source of truth.
+- Added `deepResearchDefaultEnabled` to the backend user settings allowlist because the chat UI already persists it.
+- Added regression coverage for partial chat setting saves and chat preference allowlist keys.
+
+## Validation
+
+- `node --check application/single_app/static/js/chat/chat-layout.js`
+- `python -m py_compile functional_tests/test_chat_user_setting_partial_save.py functional_tests/test_user_settings_allowlist_keys.py`
+- `python functional_tests/test_chat_user_setting_partial_save.py`
+- `python functional_tests/test_user_settings_allowlist_keys.py`
+
+## Impact
+
+Chat preference saves no longer fail because of unrelated stale workspace or group settings, and the Deep Research default preference can be saved through the same user settings route.

+# Claude Agent Tool Calling Fix
+
+Fixed/Implemented in version: **0.250.007**
+
+## Issue Description
+
+Claude-backed local Semantic Kernel agents could load actions/plugins successfully but fail to initiate plugin queries during agent turns. The model response completed normally, so users saw an answer, but no per-conversation plugin invocations were recorded for data-backed prompts.
+
+## Root Cause Analysis
+
+The Anthropic Semantic Kernel adapter was marked as not supporting function calling and only forwarded plain chat messages. Semantic Kernel therefore did not have a service-level contract for translating loaded kernel functions into Claude tool calls, even though the agent loader had already registered the SQL and schema plugins.
+
+## Technical Details
+
+Files modified:
+
+- `application/single_app/model_endpoint_clients.py`
+- `application/single_app/config.py`
+- `functional_tests/test_claude_agent_tool_calling.py`
+
+Code changes summary:
+
+- Added Anthropic tool schema conversion for Semantic Kernel/OpenAI-style function metadata.
+- Converted Anthropic `tool_use` responses into Semantic Kernel `FunctionCallContent` so the existing auto-invoke loop can run plugins.
+- Converted Semantic Kernel function call and function result history back into Anthropic `tool_use` and `tool_result` message blocks for follow-up turns.
+- For streaming Claude agent turns with tools enabled, used a non-streaming Anthropic request internally and emitted the resulting tool call or text as a stream chunk so SK auto invocation remains reliable.
+
+## Validation
+
+Test coverage:
+
+- `functional_tests/test_claude_agent_tool_calling.py`
+
+Expected behavior after the fix:
+
+- Claude-backed local agents still use the Anthropic messages protocol.
+- Loaded SQL and other Semantic Kernel plugins are exposed as Claude tools.
+- Claude `tool_use` responses trigger normal plugin execution and plugin invocation citations for the active conversation.
+
+Version reference: `application/single_app/config.py` is at **0.250.007** for this fix.

+# Collaboration Conversation Summary Export Fix (v0.241.074)
+
+Fixed/Implemented in version: **0.241.074**
+
+## Issue Summary
+
+Collaborative and multi-user conversations could not reliably generate or persist conversation summaries because the summary route and metadata helper still assumed the legacy personal conversation container.
+
+## Root Cause
+
+- The `/api/conversations/<conversation_id>/summary` route only looked up conversations in `cosmos_conversations_container` and returned `Conversation not found` for collaboration ids.
+- Summary persistence reused `update_conversation_with_metadata()`, but that helper only wrote back to the legacy conversation store.
+- The export summary path logged success even when summary persistence silently failed for collaboration conversations.
+
+## Files Modified
+
+- `application/single_app/functions_conversation_metadata.py`
+- `application/single_app/route_backend_conversations.py`
+- `application/single_app/route_backend_conversation_export.py`
+- `application/single_app/config.py`
+- `functional_tests/test_collaboration_conversation_summary_export_fix.py`
+
+## Code Changes
+
+1. Added a shared metadata loader that falls back from the legacy conversation store to the collaboration store.
+2. Updated conversation metadata persistence so collaboration conversations write summary updates back to `cosmos_collaboration_conversations_container` and refresh `updated_at`.
+3. Updated the summary route to authorize collaborative viewers and load shared messages from the collaboration store.
+4. Tightened export summary persistence logging so failed summary writes are surfaced instead of reported as successful.
+
+## Validation
+
+- Added a focused functional regression for collaboration metadata fallback, the summary route collaboration branch, and export persistence logging.
+- Focused diagnostics on the touched Python files completed without errors.
+
+## User Impact
+
+- Generate Summary now works for collaborative and multi-user conversations.
+- Export summaries for shared conversations can be cached back into the collaboration store instead of being regenerated every time.
+- Summary persistence failures in the export flow now emit a warning instead of silently reporting success.

+# Collaboration Group Agent Stream Fix
+
+Fixed/Implemented in version: **0.241.068**
+
+## Issue Description
+
+Group collaborative conversations could finish an agent run and show partial content in the UI, but the final shared stream completion step still failed and surfaced the yellow `Stream interrupted` banner.
+
+Related config update: `application/single_app/config.py` now sets `VERSION = "0.241.068"`.
+
+## Root Cause Analysis
+
+- The collaborative stream bridge emitted its final mirrored SSE payload with raw `json.dumps(...)` instead of normalizing nested values first.
+- Agent responses can carry richer citation payloads than plain model responses, including nested values that need JSON-safe normalization before the collaborative route re-emits them.
+- Hidden collaboration source conversations for group multi-user chats were also being rewritten back to `group-single-user`, which caused the inner stream path to drift away from the intended group-scoped source conversation behavior.
+
+## Technical Details
+
+Files modified:
+
+- `application/single_app/route_backend_collaboration.py`
+- `application/single_app/functions_collaboration.py`
+- `application/single_app/functions_conversation_metadata.py`
+- `functional_tests/test_collaboration_shared_ai_workflow.py`
+- `functional_tests/test_collaboration_group_agent_stream_fix.py`
+- `application/single_app/config.py`
+
+Code changes summary:
+
+- Sanitized the final mirrored collaborative SSE payload with `make_json_serializable(...)` before emitting it to the browser.
+- Synchronized hidden collaboration source conversations so group collaborative chats keep the source chat typed as `group`.
+- Preserved `group` chat typing for `collaboration_source` conversations inside conversation metadata collection instead of forcing them back to `group-single-user`.
+- Added regression coverage for both the hidden-source metadata path and the agent-citation serialization path.
+
+Testing approach:
+
+- Re-ran the existing collaboration stream bridge regression tests.
+- Added a focused functional test that simulates agent citations containing nested JSON-unsafe values and verifies the collaborative SSE completion payload remains valid.
+
+## Validation
+
+Before:
+
+- Group collaborative agent runs could produce content and citations but still fail during the final shared-stream completion step.
+- Existing hidden source conversations could drift back to `group-single-user` metadata during later metadata collection.
+
+After:
+
+- Group collaborative agent responses complete through the shared stream bridge without tripping the final collaborative stream error banner.
+- Hidden collaboration source conversations remain group-scoped, which keeps downstream streaming metadata aligned with the collaborative group workflow.

+# Collaboration Invite Access and Actions Fix
+
+Fixed/Implemented in version: **0.241.011**
+
+## Issue Description
+
+Personal conversations converted into collaborative conversations still had several broken invite and follow-up action paths.
+
+- Pending invitees could hit a 403 when the chats page tried to load collaborative messages or connect to the shared event stream before they accepted.
+- Invitees did not get a clear notification or prompt to review the invite.
+- Metadata refreshes could strip the collaborative icon and related state from the conversation list.
+- Converted personal shared chats lost expected per-user actions in the main and sidebar menus, leaving only a reduced collaboration-specific subset.
+
+## Root Cause Analysis
+
+The collaboration UI and route layer had partial support for converted personal chats, but several paths still assumed the legacy single-user conversation APIs.
+
+- Message and event access checks required accepted membership even for pre-acceptance read-only access.
+- Invite notifications depended too heavily on active conversation event flow instead of list-driven detection.
+- Metadata update helpers preserved the pin icon but not other title icons or collaboration dataset flags.
+- Main and sidebar menu actions continued calling legacy conversation endpoints for rename, pin, and hide.
+
+## Files Modified
+
+- `application/single_app/functions_collaboration.py`
+- `application/single_app/route_backend_collaboration.py`
+- `application/single_app/static/js/chat/chat-collaboration.js`
+- `application/single_app/static/js/chat/chat-conversations.js`
+- `application/single_app/static/js/chat/chat-sidebar-conversations.js`
+- `functional_tests/test_collaboration_invite_access_and_actions_fix.py`
+- `application/single_app/config.py`
+
+## Code Changes Summary
+
+- Allowed pending invitees to access collaborative message and event endpoints in read-only mode.
+- Added pending invite notification and prompt handling in the collaboration client.
+- Preserved collaboration icons and collaboration-specific dataset flags during metadata refreshes.
+- Added a shared badge for `personal_multi_user` conversations.
+- Added collaboration-aware rename, pin, and hide endpoints for personal collaborative conversations.
+- Rewired main-list and sidebar actions to call collaboration endpoints when the selected item is collaborative.
+- Guarded sidebar double-click title editing so non-managing collaborative participants are not dropped into a rename flow they cannot complete.
+
+## Testing Approach
+
+- Added a functional regression test that verifies:
+  - pending invite access allowances remain in the collaboration routes
+  - collaboration helper functions for title, pin, and hide remain available
+  - collaboration invite notification hooks remain present in the browser client
+  - main and sidebar action wiring continues to target collaboration endpoints
+
+## Impact Analysis
+
+- Invitees can now open a shared conversation and review it before responding to the invite.
+- Converted personal collaborative chats retain core per-user actions expected in the existing chat UX.
+- Collaboration state remains visibly consistent after metadata updates, reducing UI confusion.
+
+## Validation
+
+- Static diagnostics reported no new errors in the touched Python and JavaScript files.
+- The new regression test provides focused coverage for the invite-access and action-wiring paths.

+# Collaboration Invite Toast Button Fix
+
+Fixed/Implemented in version: **0.241.153**
+
+## Issue Description
+
+Pending collaboration invite notifications displayed the intended Review invite button as literal HTML text. Users saw markup such as `<strong>` and `<button>` inside the toast instead of a clickable action.
+
+## Root Cause Analysis
+
+The collaboration invite code passed an HTML string into the shared chat toast helper. The toast helper correctly rendered normal string messages with `textContent`, so the markup was escaped and shown as text. That protected the page from unsafe HTML injection, but it also meant intentional action content could not render.
+
+## Files Modified
+
+- `application/single_app/static/js/chat/chat-toast.js`
+- `application/single_app/static/js/chat/chat-collaboration.js`
+- `functional_tests/test_collaboration_invite_toast_button_fix.py`
+- `ui_tests/test_chat_collaboration_invite_toast_button.py`
+- `application/single_app/config.py`
+
+## Code Changes Summary
+
+- Updated the shared chat toast helper to accept a DOM `Node` message while keeping string messages rendered with `textContent`.
+- Rebuilt the pending collaboration invite toast with DOM APIs instead of an interpolated HTML string.
+- Assigned the conversation title through `textContent` so markup-looking titles remain inert.
+- Bound the Review invite click handler directly to the generated button.
+- Updated `application/single_app/config.py` to version `0.241.153` for this fix.
+
+## Testing Approach
+
+- Added a functional regression test that verifies the collaboration invite code uses DOM construction and that the toast helper keeps string messages as text.
+- Added a Playwright UI regression that renders a DOM-based toast message, confirms the Review invite button is clickable, and verifies a markup-looking conversation title does not create executable DOM nodes.
+
+## Impact Analysis
+
+- Pending collaboration invites now show a proper Review invite button in the toast.
+- Existing plain text toasts continue to render safely as inert text.
+- Collaboration conversation titles remain protected from XSS when rendered inside invite notifications.

+# Collaboration Message Delete Fix (v0.241.024)
+
+Fixed/Implemented in version: **0.241.024**
+
+## Issue Summary
+
+Deleting a message inside a collaborative conversation failed with a 404 because the chat UI always called the legacy personal message delete endpoint.
+
+## Root Cause
+
+- Shared messages use the collaboration message store, not the personal `cosmos_messages_container`.
+- The delete button for the current user's shared messages still posted to `/api/message/<message_id>`, so the backend looked in the wrong container and returned `Message not found`.
+- The shared delete flow also reused the personal thread-delete confirmation modal even though collaborative replies are not backed by the same retry/thread model.
+
+## Files Modified
+
+- `application/single_app/functions_collaboration.py`
+- `application/single_app/route_backend_collaboration.py`
+- `application/single_app/static/js/chat/chat-collaboration.js`
+- `application/single_app/static/js/chat/chat-messages.js`
+- `application/single_app/config.py`
+- `functional_tests/test_collaboration_message_delete_fix.py`
+
+## Code Changes
+
+1. Added a collaboration helper that deletes a shared message from the collaboration container and recalculates `message_count`, `last_message_preview`, and `last_message_at`.
+2. Added a dedicated shared-message delete route at `/api/collaboration/conversations/<conversation_id>/messages/<message_id>`.
+3. Published a `collaboration.message.deleted` live event so other participants' open chat views remove the deleted message without a manual refresh.
+4. Updated the chat UI to route shared-message deletes to the collaboration API instead of the personal message delete endpoint.
+5. Switched shared user-message deletes to the single-message confirmation flow instead of the personal thread-delete modal.
+6. Updated the collaboration event replay guard so cached delete events use UTC-aware timestamp parsing and no longer re-show stale "A shared message was deleted." toasts on conversation reload.
+
+## Validation
+
+- Added a functional regression covering the helper behavior, the collaboration delete route contract, the published live delete event, and the frontend endpoint wiring.
+- Focused editor diagnostics on the modified JavaScript, Python, and markdown files completed without errors.
+
+## User Impact
+
+- Deleting your own message in a collaborative conversation now succeeds instead of returning `Message not found`.
+- Shared conversation previews stay in sync after deletion.
+- Other participants with the shared conversation open see the deleted message disappear via the collaboration event stream.
+- Reloading or reopening a collaborative conversation no longer replays old shared-delete toast notifications from cached event history.

+# Collaboration Message Notification Fix (v0.241.016)
+
+Fixed/Implemented in version: **0.241.016**
+
+## Issue Summary
+
+Shared conversations showed short-lived yellow toast notices on the chat page, but those alerts disappeared quickly and did not leave a persistent notification in the notifications inbox. Users could miss a new shared message or tag if they were not actively looking at the conversation when the toast appeared.
+
+## Root Cause
+
+- The collaboration event stream only produced browser toasts for the currently open shared conversation.
+- Shared-message posts did not create notification-service records, so nothing appeared on the notifications page or in the bell badge.
+- Opening a collaborative conversation had no mark-read endpoint for collaboration notifications, so there was no inbox lifecycle equivalent to the existing personal AI completion flow.
+
+## Files Modified
+
+- `application/single_app/functions_notifications.py`
+- `application/single_app/functions_collaboration.py`
+- `application/single_app/route_backend_collaboration.py`

+- `application/single_app/config.py`
+- `functional_tests/test_collaboration_message_notifications.py`
+- `ui_tests/test_chat_collaboration_ui_scaffolding.py`
+
+## Code Changes
+
+1. Added a new `collaboration_message_received` notification type in the notification service.
+2. Added a collaboration notification helper that creates a deep link to `/chats?conversationId=...`, matching the existing chat-completion navigation pattern.
+3. Added recipient fan-out for shared-message posts so accepted personal-collaboration participants and eligible group-collaboration members receive personal inbox notifications, excluding the sender.
+4. Preserved mention context in the notification metadata so tagged recipients get a stronger inbox title.
+5. Added a shared `mark-read` collaboration API and wired chat activation to clear collaboration notifications when the recipient opens the shared conversation or is already actively viewing it.
+
+## Validation
+
+- Added a functional regression covering helper deep links, recipient fan-out, group recipient resolution, and the collaboration mark-read route.
+- Updated the collaboration UI scaffolding test to assert that shared conversation activation calls the collaboration mark-read endpoint.
+- Focused diagnostics were run on the modified Python, JavaScript, and documentation files.
+
+## User Impact
+
+- Shared-message alerts now persist in the notifications inbox instead of disappearing with only a short toast.
+- Notification clicks deep-link back into the shared conversation just like personal AI completion notifications.
+- Shared notifications clear when the user opens the collaborative conversation, keeping the bell badge aligned with what the user has actually read.

+# Collaboration Metadata And Participant Mention Fix (v0.241.017)
+
+Fixed/Implemented in version: **0.241.017**
+
+## Issue Summary
+
+Shared conversations had two gaps:
+
+1. Collaboration user-message metadata was returned as a thin internal metadata fragment, so the drawer often showed little or no useful information for participant messages.
+2. Typing `@` in a collaborative conversation always behaved like an invite flow, even when the selected person was already an active participant and should have been tagged in the message instead.
+
+## Root Cause
+
+- The shared metadata route fell back to collaboration documents, but it returned the raw collaboration payload instead of a drawer-friendly metadata shape.
+- Collaborator message bubbles did not expose their own metadata toggle, so other participants could not inspect message metadata from the conversation UI.
+- Collaboration mention suggestions only searched invite candidates and never prioritized or recognized accepted participants already in the conversation.
+
+## Files Modified
+
+- `application/single_app/collaboration_models.py`
+- `application/single_app/functions_collaboration.py`
+- `application/single_app/route_backend_collaboration.py`
+- `application/single_app/route_frontend_conversations.py`

+- `application/single_app/config.py`
+- `functional_tests/test_collaboration_metadata_and_mentions_fix.py`
+- `ui_tests/test_chat_collaboration_ui_scaffolding.py`
+
+## Code Changes
+
+1. Collaboration message metadata is now normalized before it reaches the drawer, including shared message details, sender info, reply context, tagged participants, collaboration context, and legacy file or image metadata where available.
+2. Legacy collaboration message copies now retain more of the original metadata so file, image, and AI details survive when a personal conversation is converted into a collaborative conversation.
+3. Collaborator message bubbles now expose the same metadata drawer access pattern as shared messages sent by the current user.
+4. The collaboration `@` suggestion menu now distinguishes between:
+   - existing accepted participants, which are inserted as visible message tags
+   - other collaborator suggestions, which still follow the participant invite flow when the current user can add members
+5. Shared messages now persist mentioned participant metadata and show a mention toast when another participant tags the current user.
+6. Shared message rendering now removes raw `@Display Name` text from the body when that mention is already represented by structured collaboration tag metadata, so senders and recipients see the tag treatment instead of duplicated plain-text mentions.
+
+## Validation
+
+- Added a functional regression that locks in collaboration metadata normalization, collaborator metadata toggles, and participant mention tagging.
+- Updated the collaboration UI scaffolding test to assert the visible mention-chip styling contract.
+- Editor diagnostics on the modified Python, JavaScript, CSS, and route files completed without errors.
+
+## User Impact
+
+- All participants in a collaborative conversation can inspect metadata for shared human, AI, file, and image messages through the same conversation UI.
+- `@` now behaves as an in-message tag for existing participants instead of incorrectly trying to invite them again.
+- Mentioned participants receive a clearer visual signal inside the message bubble and an explicit toast when another user tags them.
+- Tagged shared messages no longer show duplicated raw `@name` text in the rendered message body when the tag metadata is already present.

+# Collaboration Participant Picker Helper Fix (v0.241.010)
+
+Fixed and implemented in version: **0.241.010**
+
+## Issue Description
+
+Clicking Add participants from the chat UI could throw a browser-side runtime error:
+
+- `ReferenceError: isCollaborativeConversation is not defined`
+
+The failure occurred before the participant picker modal opened, so eligible personal conversations could not be upgraded into collaborative conversations from the sidebar or details actions.
+
+## Root Cause Analysis
+
+The collaboration module had already standardized on `isCollaborationConversation(...)`, but the participant gating helpers still referenced the old helper name `isCollaborativeConversation(...)` in two paths:
+
+- participant-flow eligibility checks
+- collaborative message-post permission checks
+
+Because the old helper no longer existed, the add-participants workflow failed immediately when the gate ran.
+
+## Technical Details
+
+### Files Modified
+
+- `application/single_app/static/js/chat/chat-collaboration.js`
+- `ui_tests/test_chat_collaboration_ui_scaffolding.py`
+- `application/single_app/config.py`
+
+### Code Changes Summary
+
+- Replaced stale `isCollaborativeConversation(...)` references with `isCollaborationConversation(...)`.
+- Extended the chat collaboration UI regression to call `openParticipantPicker(...)` with a mocked eligible personal conversation and assert that the participant modal opens.
+
+### Testing Approach
+
+- Static editor diagnostics for the updated collaboration UI files
+- Updated Playwright UI scaffolding regression for the add-participants entry path
+
+## Validation
+
+### Test Results
+
+- The updated UI test module loads successfully and skips cleanly when authenticated Playwright storage state is not available in the environment.
+
+### Before And After
+
+- Before: clicking Add participants could fail immediately with a `ReferenceError`.
+- After: the participant-flow eligibility check uses the defined collaboration helper and allows the modal path to proceed for eligible personal conversations.
+
+### User Experience Improvements
+
+- Sidebar and details-based participant adds no longer fail on helper-name drift.
+- The personal-to-collaborative upgrade path is available again from the existing chat UI actions.

+# Collaboration Reply And Avatar Fix (v0.241.014)
+
+Fixed/Implemented in version: **0.241.014**
+
+## Issue Description
+
+Shared conversations still felt incomplete in three visible ways:
+
+1. Other participants could show a broken or collapsed avatar inside shared message bubbles, even when a profile image existed.
+2. Shared join, removal, and role-change toasts could replay when a user re-opened the same shared conversation because the event stream cached historical events.
+3. Shared chats did not expose a reply workflow, so users could not quote and answer a specific participant message from the conversation timeline.
+
+## Root Cause Analysis
+
+The collaboration UI already loaded participant avatars in the conversation details modal and persisted `reply_to_message_id` in the collaboration route, but the chat transcript and composer did not reuse either capability.
+
+- Shared message rendering used a custom collaborator avatar wrapper instead of the same top-level avatar image styling used elsewhere in chat.
+- The collaborator avatar flex item could shrink under the shared-message layout, which caused profile images to collapse into a thin strip on the left edge of the row.
+- The collaboration event client reattached to a replayable event cache without suppressing historical events, so stale toasts were shown again on re-entry.
+- The compose area had no reply target state, no reply preview container, and no user-message action for selecting a reply target.
+
+## Files Modified
+
+1. `application/single_app/static/js/chat/chat-collaboration.js`
+2. `application/single_app/static/js/chat/chat-messages.js`
+3. `application/single_app/static/css/chats.css`
+4. `application/single_app/templates/chats.html`
+5. `ui_tests/test_chat_collaboration_ui_scaffolding.py`
+6. `functional_tests/test_collaboration_reply_and_avatar_fix.py`
+7. `application/single_app/config.py`
+
+## Code Changes Summary
+
+1. Added composer-level reply state for collaborative conversations, including a dismissible reply preview panel above the chat input.
+2. Added a Reply action to collaborator message menus and rendered quoted reply context inside shared user and collaborator bubbles.
+3. Reused the existing per-user profile image endpoint to hydrate collaborator avatars in shared message bubbles, with initials as the fallback state.
+4. Switched hydrated collaborator avatars onto the same top-level avatar image element used by the standard chat rows and locked the avatar slot to a fixed flex width so it cannot collapse.
+5. Added replay-event suppression in the collaboration event client so cached invite, removal, and role-change events do not re-toast each time a shared conversation is reselected.
+6. Updated the collaboration UI regression and added a functional regression file that locks in the reply-preview, avatar, and replay-suppression hooks.
+
+## Testing Approach
+
+1. Updated `ui_tests/test_chat_collaboration_ui_scaffolding.py` to validate the reply preview container and reply selection behavior.
+2. Added `functional_tests/test_collaboration_reply_and_avatar_fix.py` to verify the relevant collaboration UI hooks remain present.
+3. Ran file diagnostics on the modified JavaScript, CSS, HTML, and Python files.
+
+## Validation
+
+### Before
+
+1. Collaborator bubbles showed the generic avatar even when profile images were available.
+2. Reopening a shared conversation could replay old green collaboration toasts from the cached SSE session.
+3. Users had no targeted reply workflow in shared chats.
+
+### After
+
+1. Shared collaborator bubbles can show the participant profile image when one exists and otherwise fall back to initials, without collapsing the avatar width.
+2. Historical collaboration events are ignored when reconnecting to a shared conversation, which prevents repeated join or role-change toasts.
+3. Users can reply to another participant, see the quoted reply target above the composer, and keep the quoted context in the resulting shared message bubble.

+# Collaboration Shared AI Workflow Fix
+
+Fixed/Implemented in version: **0.241.021**
+
+## Overview
+
+Collaborative conversations were still posting plain shared messages even when the chat toolbar had an active workspace search, web search, image generation, prompt, or agent selection. That meant shared conversations did not enter the same model and agent workflow that single-user chat already uses.
+
+The shared composer also did not provide an explicit way to target a model without turning on a tool. Users could tag participants, but they could not tag an available model or agent as a first-class AI target in the same shared conversation.
+
+## Root Cause
+
+The collaboration composer only posted to the shared message endpoint with message text, reply metadata, and participant mentions. The single-user orchestration path lives behind `/api/chat/stream`, so the shared flow never carried model selection, agent selection, workspace scope, document selections, web search, image generation, or reasoning settings into the AI workflow.
+
+On the frontend, the `@` suggestion menu was limited to human participants and invite suggestions. Because explicit `@model` and `@agent` tags were never parsed into `ai_invocation_target` metadata, a no-tool shared send still fell back to a plain collaborative message instead of the AI streaming path.
+
+## What Changed
+
+- Added a collaborative streaming route that saves the shared AI request, proxies the existing `/api/chat/stream` workflow against a hidden backing source conversation, and mirrors the final assistant or image response back into the collaboration message store.
+- Extended collaboration persistence helpers so shared messages can be stored as explicit `ai_request` messages and can mirror source assistant/image messages without losing source linkage or thought access.
+- Reused the existing single-user frontend request builder so shared AI sends use the same payload for model, agent, workspace, web, image, prompt, and reasoning settings.
+- Added a visible invocation target chip to shared AI request messages so the sender and participants can see whether the request targeted `@Image`, a selected agent, or the current model.
+- Added collaboration-side rendering support for mirrored image responses.
+- Extended the collaboration `@` suggestion menu so it now surfaces available agents and available models alongside participant tags and invite suggestions.
+- Added explicit `@agent` and `@model` parsing so shared sends can target AI without selecting a toolbar tool, and the raw `@target` text is stripped from the final message body in favor of a structured chip.
+- Split shared chip styling so participant mentions, agent targets, and model targets render with different background colors.
+- Updated the streaming chat bridge so explicit tagged-agent requests stamp `agent_selection` and the actual resolved model onto the hidden source user message metadata, which keeps shared user-message detail panels aligned with the assistant response.
+- Synced source conversation tags and context metadata back into the collaborative conversation record after streaming completes so shared conversation details reflect the resolved agent and actual model used.
+
+## Files Modified
+
+- `application/single_app/functions_collaboration.py`
+- `application/single_app/route_backend_collaboration.py`
+- `application/single_app/static/js/chat/chat-collaboration.js`
+- `application/single_app/static/js/chat/chat-messages.js`
+- `application/single_app/static/js/chat/chat-streaming.js`
+- `application/single_app/static/css/chats.css`
+- `application/single_app/config.py`
+
+## Validation
+
+- Added regression coverage in `functional_tests/test_collaboration_shared_ai_workflow.py`.
+- Extended `ui_tests/test_chat_collaboration_ui_scaffolding.py` to cover target-specific chip styling and `@` suggestion rendering for agents and models.
+- Verified diagnostics were clean for the touched backend and frontend files.
+
+## User Impact
+
+- Shared workspace and web requests now enter the same model or agent workflow as single-user chat.
+- Shared image requests now route to image generation and mirror the resulting image back into the collaboration conversation.
+- Shared AI requests now display an explicit target chip instead of silently acting like a plain participant message.
+- Shared conversation authors can now type `@Default Agent` or `@gpt-5.4` to direct a message to an agent or model without selecting a tool first.
+- Shared participant tags, agent targets, and model targets now render as visually distinct chips.
+- Shared user-message metadata now shows the tagged agent and the actual resolved model instead of only the dropdown model selection.
+- Shared conversation details now inherit the resolved model and agent tags from the hidden source conversation after AI completion.

+# Collaboration Shared Conversation Management Fix
+
+Fixed/Implemented in version: **0.241.012**
+
+## Issue Description
+
+Shared personal conversations still had several gaps after the first collaboration rollout:
+
+1. Accepting an invite could leave the conversation details backdrop behind.
+2. Converted assistant messages carried citations into shared chats, but processing thoughts and metadata were still resolved through legacy-only routes.
+3. The sender could briefly see the same collaborative message twice until the conversation refreshed.
+4. Shared conversations had no admin-role promotion path for invite management.
+5. Export and delete or leave actions were missing from the shared conversation details flow.
+6. Conversation deletion still relied on browser confirm dialogs instead of Bootstrap modal dialogs.
+
+## Root Cause Analysis
+
+The collaboration feature had landed as a parallel conversation model, but several supporting systems still assumed legacy single-owner conversations:
+
+1. The details modal was reopened during invite acceptance without a clean Bootstrap modal teardown.
+2. Thought retrieval, message metadata lookup, and conversation export only queried legacy message and thought stores.
+3. Collaborative sending used an optimistic local user bubble, a direct POST-response render, and the shared SSE event, so the sender had multiple render paths.
+4. Personal collaboration membership only modeled `owner` and `member`, so there was no safe way to delegate invite capability.
+5. Shared delete semantics were never designed into the existing legacy delete flow.
+
+## Files Modified
+
+1. `application/single_app/collaboration_models.py`
+2. `application/single_app/functions_collaboration.py`
+3. `application/single_app/route_backend_collaboration.py`
+4. `application/single_app/route_frontend_conversations.py`
+5. `application/single_app/route_backend_thoughts.py`
+6. `application/single_app/route_backend_conversation_export.py`

+12. `application/single_app/static/js/chat/chat-messages.js`
+13. `application/single_app/templates/chats.html`
+
+## Code Changes Summary
+
+1. Added an `admin` membership role for personal collaborative conversations.
+2. Added backend routes for participant role updates and shared delete or leave actions.
+3. Added owner transfer-on-leave support for shared personal conversations.
+4. Added collaboration-aware message metadata, shared thought fallback, and shared conversation export support.
+5. Reconciled optimistic collaborative message rendering so the sender no longer sees duplicate user messages.
+6. Added shared Export and Delete or Leave actions to the Conversation Details modal.
+7. Replaced single-conversation browser confirm deletion with a Bootstrap modal that supports shared transfer-and-leave flows.
+8. Added modal cleanup logic so invite acceptance no longer leaves a stale backdrop.
+
+## Testing Approach
+
+1. Added `functional_tests/test_collaboration_shared_conversation_management_fix.py`.
+2. Updated `ui_tests/test_chat_collaboration_ui_scaffolding.py` to cover the new details footer actions and shared delete or leave modal scaffolding.
+3. Ran file diagnostics on the modified Python, JavaScript, and HTML files.
+
+## Validation
+
+### Before
+
+1. Shared thoughts and metadata stopped at legacy boundaries.
+2. Collaborative sender bubbles could double-render.
+3. Shared details actions were incomplete.
+4. Shared delete used browser confirmation and had no ownership transfer path.
+
+### After
+
+1. Converted shared transcripts can resolve assistant metadata and processing thoughts through collaboration-aware fallbacks.
+2. Collaborative user sends reconcile the optimistic bubble against the persisted shared message id.
+3. Owners can promote or demote admins from the details modal, and admins inherit invite access.
+4. Shared details now expose Export plus Delete or Leave actions with Bootstrap modal UX.

+# Collaboration Typing Deactivation Fix (v0.241.009)
+
+Fixed and implemented in version: **0.241.009**
+
+## Issue Description
+
+Switching away from a collaborative conversation could throw a browser-side runtime error:
+
+- `ReferenceError: isCollaborationConversation is not defined`
+
+The failure occurred inside the collaboration typing shutdown path when the chat UI deactivated collaborative event handling.
+
+## Root Cause Analysis
+
+The collaboration module referenced `isCollaborationConversation(...)` from multiple internal code paths but never defined the helper as a local function.
+
+The deactivation flow also cleared its active collaborative conversation state before typing shutdown had a stable conversation ID to work with, which made the shutdown path unnecessarily fragile during conversation switches.
+
+## Technical Details
+
+### Files Modified
+
+- `application/single_app/static/js/chat/chat-collaboration.js`
+- `ui_tests/test_chat_collaboration_ui_scaffolding.py`
+- `application/single_app/config.py`
+
+### Code Changes Summary
+
+- Added a local `isCollaborationConversation(...)` helper in the collaboration module and reused it for the exported API.
+- Updated collaborative deactivation to preserve the previous collaborative conversation ID while shutting down typing state.
+- Cleared pending typing timers during deactivation so old timers do not fire after switching away.
+- Added a UI regression that exercises `window.chatCollaboration.deactivateConversation()` with a mocked collaborative conversation item.
+
+### Testing Approach
+
+- Static editor diagnostics for the updated collaboration UI files
+- Existing collaboration functional tests
+- Updated Playwright UI scaffolding test for the deactivation path
+
+## Validation
+
+### Test Results
+
+- Collaboration functional tests still pass after the fix.
+- The updated UI test module loads successfully and skips cleanly when authenticated Playwright storage state is not available in the environment.
+
+### Before And After
+
+- Before: switching away from a collaborative conversation could raise a `ReferenceError` in `chat-collaboration.js`.
+- After: the collaboration module deactivates cleanly and typing shutdown uses a stable helper and conversation reference.
+
+### User Experience Improvements
+
+- Conversation switching no longer breaks collaborative chat state handling.
+- Shared chat typing cleanup is more predictable when leaving a collaborative conversation.

+# Collaborative Image Proposal Rehydration Fix
+
+Fixed/Implemented in version: **0.241.144**
+
+## Issue Description
+
+When a personal conversation with approved inline image proposal cards was converted into a multi-user conversation by adding a participant, the generated images could lose their inline placement. The shared conversation could render the saved generated image as a separate message and leave the original proposal card looking unapproved.
+
+## Root Cause Analysis
+
+Legacy-to-collaboration conversion creates new collaboration message IDs. Generated image messages preserved `metadata.image_proposal.source_assistant_message_id`, but that value still pointed at the old personal assistant message ID. The collaboration frontend also loaded messages one at a time and did not reuse the personal chat logic that folds saved generated proposal images back into their source assistant card.
+
+## Technical Details
+
+Files modified:
+
+- `application/single_app/collaboration_models.py`
+- `application/single_app/functions_collaboration.py`
+- `application/single_app/static/js/chat/chat-messages.js`
+- `application/single_app/static/js/chat/chat-collaboration.js`
+- `functional_tests/test_collaboration_inline_image_proposal_porting_fix.py`
+- `application/single_app/config.py`
+
+Code changes summary:
+
+- Added a pure metadata translator that rewrites `metadata.image_proposal.source_assistant_message_id` from the legacy assistant message ID to the copied collaboration assistant message ID.
+- Applied that translation for both personal-to-collaboration and group-to-collaboration legacy message copy paths before saving copied messages.
+- Exported the generated image proposal grouping helpers from the personal chat renderer.
+- Updated the collaboration message loader and live event renderer to fold generated proposal image messages into the source assistant card instead of rendering a duplicate standalone image bubble.
+- Updated the application version in `config.py` to `0.241.144`.
+
+## Validation
+
+Validation approach:
+
+- Functional coverage verifies the metadata translation and the collaboration frontend folding contract.
+- JavaScript syntax validation covers the changed chat modules.
+- Python compile validation covers the changed backend modules and the new functional test.
+
+Expected behavior:
+
+- Adding a participant to a personal conversation with approved image proposal cards keeps generated images inline in the converted shared conversation.
+- Reloading a collaborative conversation does not make already-approved image proposal cards ask for approval again.
+- Generated proposal images that arrive while a shared conversation is open are attached to the rendered source assistant card when possible.

+# Control Center Management Pagination Fix - v0.241.024
+
+Fixed in version: **0.241.024**
+
+## Issue Description
+
+Control Center user management had pagination, but the page size was fixed from the client workflow and did not expose the same selectable page-size control used elsewhere. Group management and public workspace management requested a fixed page from the API, so larger result sets could not be navigated from those views.
+
+## Root Cause Analysis
+
+The user management API accepted pagination parameters, but the UI did not expose a page-size selector. The group and public workspace management views rendered pagination placeholders in the template, but the JavaScript hard-coded API calls to the first page with a fixed page size and did not render usable pagination controls.
+
+## Version Implemented
+
+Implemented in version: **0.241.024**
+
+The application version was updated in `application/single_app/config.py` from `0.241.023` to `0.241.024` for this code change.
+
+## Technical Details
+
+Files modified:
+
+- `application/single_app/route_backend_control_center.py`
+- `application/single_app/templates/control_center.html`
+- `application/single_app/static/js/control-center.js`
+- `application/single_app/config.py`
+- `functional_tests/test_control_center_management_pagination.py`
+- `ui_tests/test_control_center_management_pagination.py`
+
+Code changes summary:
+
+- Added shared backend pagination parsing for Control Center management tables with a default of 25 and a maximum of 250 items per page.
+- Added page-size selectors for user, group, and public workspace management using 10, 25, 50, 100, and 250 options.
+- Added server-driven pagination rendering for group management and public workspace management.
+- Removed hard-coded `page=1` and `per_page=100` requests from group and public workspace loading.
+- Added server-side group status filtering and aligned public workspace status filtering with paginated totals.
+
+## Testing Approach
+
+- Added a source-level functional regression test to validate backend pagination helpers, template controls, and JavaScript pagination state.
+- Added a Playwright UI test that verifies all three selectors expose the same options and that selected values are sent to the corresponding API endpoints.
+
+## Impact Analysis
+
+Admins can now choose page sizes consistently across user management, group management, and public workspace management. Group and public workspace result sets can be paged without relying on oversized first-page requests, and pagination totals now reflect server-side filters.
+
+## Validation
+
+Before:
+
+- Users were limited to the client’s fixed page-size behavior.
+- Groups and public workspaces requested a fixed first page and did not provide usable navigation.
+
+After:
+
+- Users, groups, and public workspaces all expose the same page-size selector.
+- Groups and public workspaces render pagination controls and send the selected page and page size to the API.
+- Backend pagination defaults, limits, and clamping are shared across all three management endpoints.

+# Conversation Early Title Update Fix (v0.241.042)
+
+## Issue Description
+
+New chat conversations could remain titled **New Conversation** until the full assistant response completed. This was most visible for document analysis or comparison requests where `_execute_document_action_workflow(...)` can run for many minutes across many documents, windows, and chunks.
+
+## Root Cause Analysis
+
+The document-action chat path created or loaded the conversation and saved the user's message, but only derived the conversation title after the long document workflow returned. The streaming client also only applied conversation title metadata from the final terminal SSE event, so even standard streaming requests did not update the visible title as early as the backend could determine it.
+
+## Fixed/Implemented in version: **0.241.042**
+
+The application version for this fix is tracked in `application/single_app/config.py` as `0.241.042`.
+
+## Technical Details
+
+### Files Modified
+
+- `application/single_app/functions_simplechat_operations.py`
+- `application/single_app/route_backend_conversations.py`
+- `application/single_app/route_backend_chats.py`

+- `application/single_app/config.py`
+- `functional_tests/test_chat_early_conversation_title.py`
+- `ui_tests/test_chat_stream_early_title_update.py`
+
+### Code Changes Summary
+
+- Added a shared `derive_conversation_title_from_message(...)` helper that collapses whitespace and derives the same short title used by existing chat title behavior.
+- Updated `/api/create_conversation` to accept the first submitted message and create the conversation with a useful initial title.
+- Updated document-action chat execution to persist the derived title before `_execute_document_action_workflow(...)` begins.
+- Added a `conversation_metadata` SSE payload for early title updates during streaming responses.
+- Updated the chat streaming client to apply early metadata events with DOM text APIs so untrusted titles remain inert.
+
+### Testing Approach
+
+- Added functional coverage that checks the server-side ordering: title persistence and metadata streaming hooks occur before the document-action workflow starts.
+- Added UI coverage that imports the streaming client and verifies early metadata updates the active conversation title without rendering HTML from the title text.
+
+## Impact Analysis
+
+Users see a meaningful conversation title immediately after submitting the first message, including long-running Analyze and Compare workflows. Final conversation metadata still updates at completion, so scope, classifications, context, and assistant response details continue to be enriched by the existing flow.
+
+## Validation
+
+Before the fix, a long-running document action left the sidebar/header on **New Conversation** until the workflow completed. After the fix, the title is derived from the submitted message and applied before document processing begins, with a stream metadata event keeping the active browser UI in sync.

+# Conversation Summary Claude Endpoint Fix
+
+Fixed/Implemented in version: **0.241.182**
+
+## Issue Description
+
+Conversation export summary intros and the Chat Details "Generate Summary" action could fail when the selected summary model was a Claude deployment from a configured Foundry or New Foundry model endpoint. The summary helper only created the legacy Azure OpenAI client, so Claude deployments were sent through the wrong API shape and could return `DeploymentNotFound` or API-version errors.
+
+## Root Cause Analysis
+
+Direct chat and endpoint tests had protocol-aware model endpoint resolution, but the shared summary generator still resolved only APIM or the default Azure OpenAI GPT configuration. The summary UI also sent only the deployment name, dropping the endpoint id, model id, and provider metadata already available on the chat model selector.
+
+## Technical Details
+
+Files modified:
+
+- `application/single_app/route_backend_conversation_export.py`
+- `application/single_app/route_backend_conversations.py`
+- `application/single_app/static/js/chat/chat-export.js`
+- `application/single_app/static/js/chat/chat-conversation-details.js`
+- `application/single_app/config.py`
+- `functional_tests/test_conversation_summary_model_endpoint_protocol.py`
+
+Code changes summary:
+
+- Added summary-specific model endpoint resolution that checks configured global, personal, and group endpoints before falling back to APIM or default Azure OpenAI settings.
+- Routed Claude summary models through the Anthropic messages adapter and OpenAI-compatible Foundry models through the `/openai/v1` adapter.
+- Preserved existing Azure OpenAI behavior for non-endpoint summary models.
+- Passed endpoint id, model id, and provider metadata from export summary and Chat Details summary requests.
+- Added regression coverage for explicit endpoint metadata and deployment-only Claude summary resolution.
+
+## Validation
+
+Test results:
+
+- `python -m py_compile application/single_app/route_backend_conversation_export.py application/single_app/route_backend_conversations.py functional_tests/test_conversation_summary_model_endpoint_protocol.py`
+- `node --check application/single_app/static/js/chat/chat-export.js`
+- `node --check application/single_app/static/js/chat/chat-conversation-details.js`
+- `python functional_tests/test_conversation_summary_model_endpoint_protocol.py`
+
+Before this fix, Claude summary generation could be attempted against the configured Azure OpenAI endpoint even when the selected chat model came from a Claude-capable model endpoint. After this fix, export summaries and Chat Details summaries resolve the selected endpoint metadata and use the correct runtime protocol.
+
+Version reference: `application/single_app/config.py` is at **0.241.182** for this fix.

The prior implementation used a hard-coded 300-second scheduler sleep, which happened to match the default five-minute Metrics Window but did not follow the setting if admins changed it.
+
+## Root Cause Analysis
+
+The Metrics Window setting controlled only the Azure Monitor lookback range. The background scheduler loop slept for a fixed five minutes, and background logs were not clearly distinguishable from manual Admin Settings Refresh logs.

+# Cosmos Container Metrics Dimension Fix
+
+Fixed/Implemented in version: **0.241.154**
+
+## Issue Description
+
+The Admin Settings Scale tab could show an aggregate Cosmos RU Utilization value, such as 11%, while every dedicated-throughput container row still showed `RU Utilization: Not available` and `Request Units: Not available`.
+
+## Root Cause Analysis
+
+The throughput refresh queried Azure Monitor for `NormalizedRUConsumption` and `TotalRequestUnits` without requesting Cosmos database and container dimensions. Azure Monitor could return a valid account-level metric series for the status card, but the response did not include `CollectionName` container metadata for the table rows.
+
+## Technical Details

+- `ui_tests/test_admin_cosmos_throughput_settings_ui.py`
+- `docs/explanation/release_notes.md`
+
+Code changes summary:
+
+- Added an Azure Monitor metrics query path that requests Cosmos container dimensions with `DatabaseName eq '*' and CollectionName eq '*'`.
+- Kept an aggregate metrics fallback so the top-level RU utilization card remains populated when container-dimensional metrics lag or are not returned.
+- Added backend logging fields for whether container dimensions were requested and how many container metric rows were returned.
+- Added an Admin Settings warning when Azure Monitor returns aggregate utilization but no per-container metric dimensions for the selected window.
+- Application version updated to `0.241.154` in `application/single_app/config.py`.
+
+## Validation
+
+Test results:
+
+- Python syntax validation for `functions_cosmos_throughput.py` and the new metric regression test.
+- Functional regression test for Cosmos Azure Monitor container metric parsing, dimension filter usage, and aggregate fallback behavior.
+- JavaScript syntax validation for `admin_settings.js`.
+- Focused UI regression test for the aggregate-only metrics warning.
+
+Before/after comparison:
+
+- Before: the refresh path often populated only the aggregate RU Utilization card, leaving all container rows without metric values.

+# Cosmos Container Metrics REST Metadata Fix
+
+Fixed/Implemented in version: **0.241.156**
+
+## Issue Description
+
+The Admin Settings Scale tab still showed `Not available` for every container's RU Utilization and Request Units even though Azure Metrics Explorer showed per-container `Normalized RU Consumption` and total request-unit metrics for the same Cosmos account.
+
+## Root Cause Analysis
+
+The Azure Monitor Query SDK returned the correct number of container-split time series, but the SDK model exposed blank metadata entries for those series. The app saw the metric values but could not map each series to a Cosmos container name. The raw Azure Monitor Metrics REST API returned the same series with usable `collectionname` and `databasename` metadata, matching the portal view.

+- `docs/explanation/release_notes.md`
+
+Code changes summary:
+
+- Removed the Cosmos throughput metrics dependency on the Azure Monitor Query SDK response model.
+- Added a raw Azure Monitor Metrics REST request for `NormalizedRUConsumption,TotalRequestUnits` with `Maximum,Total` aggregation and the existing database/container dimension filter.
+- Extended metric metadata parsing to support REST `metadatavalues` dictionaries with lowercase `collectionname` and `databasename` keys.
+- Reused one metrics ARM token/context across the container-dimensional query and aggregate fallback query.
+- Application version updated to `0.241.156` in `application/single_app/config.py`.
+
+## Validation
+
+Test results:
+
+- Live read-only metrics probe confirmed named container rows are returned for the configured Cosmos account.
+- Functional regression test now uses REST-shaped metric payloads instead of SDK-shaped fake objects.
+- Python and JavaScript syntax validation completed for touched files.
+- Focused Cosmos throughput regression suite completed successfully.
+
+Before/after comparison:
+
+- Before: Azure returned container-split metric series, but the SDK metadata loss left every container row unmapped and displayed as unavailable.
+- After: SimpleChat parses the raw Metrics REST metadata and fills row-level RU Utilization and Request Units for individual containers.

+# Cosmos Container Throughput Deployer Fix
+
+Fixed in version: **0.241.206**
+Deployer version: **1.0.14**
+
+## Issue Description
+
+New `azd up` deployments could fail during Gunicorn worker startup with a Cosmos DB error similar to:
+
+```text
+Collection create forbidden as collection count in database offer has exceeded 25.
+```
+
+The application imports `config.py` during worker boot and opens or creates all SimpleChat Cosmos containers. The deployer created the `SimpleChat` database with shared autoscale throughput, and Cosmos DB limits shared-throughput databases to 25 containers. Current SimpleChat deployments require more than 25 application containers.
+
+## Root Cause Analysis
+
+The deployment model used a provisioned Cosmos DB account, but attached the autoscale throughput offer to the `SimpleChat` SQL database. That made the database a shared-throughput database. When app startup reached the 26th container, Cosmos rejected the create operation even though the account itself was healthy and provisioned.
+
+## Technical Details
+
+Files modified:
+
+- `deployers/bicep/modules/cosmosDb.bicep`
+- `deployers/bicep/main.bicep`
+- `deployers/bicep/main.json`
+- `deployers/azurecli/deploy-simplechat.ps1`
+- `deployers/terraform/main.tf`

+- `functional_tests/test_deployer_capacity_defaults.py`
+- `docs/explanation/features/v0.241.085/DEPLOYER_CAPACITY_DEFAULTS.md`
+
+Code changes summary:
+
+- Provisioned Cosmos deployments now create the `SimpleChat` SQL database without a shared database throughput offer.
+- SimpleChat containers are pre-created with dedicated autoscale throughput in provisioned mode.
+- The default autoscale max is now 1000 RU/s per container.
+- The existing `cosmosDatabaseAutoscaleMaxThroughput` Bicep parameter name is retained for deployment compatibility, but it now controls per-container autoscale max RU/s.
+- Serverless Cosmos deployments continue to create containers without throughput settings.
+
+## Testing Approach
+
+Validation is covered by `functional_tests/test_deployer_capacity_defaults.py`, which checks the Bicep, generated one-click ARM template, Azure CLI deployer, Terraform deployer, documentation, application version, and deployer version.
+
+## Impact Analysis
+
+New provisioned deployments avoid the shared-throughput 25-container limit and should no longer fail at startup when SimpleChat reaches containers such as `public_workspace_identities`.
+
+Existing deployments that already have a shared-throughput `SimpleChat` database may require an intentional migration plan because removing a shared database throughput offer is not generally an in-place Bicep update. Those environments should be reviewed before rerunning infrastructure deployment.
+
+## Validation
+
+Before:
+
+- `azd up` created a shared-throughput `SimpleChat` database.
+- App startup attempted to create more than 25 containers under that database offer.
+- Gunicorn workers failed to boot with the Cosmos container-count error.
+
+After:
+
+- The deployer creates the database and all expected SimpleChat containers.
+- Provisioned throughput is assigned at the container level.
+- The app can open existing containers during startup without hitting the shared database container limit.

+# Cosmos Container Throughput Fallback Fix
+
+Fixed/Implemented in version: **0.241.148**
+
+## Issue Description
+
+The Admin Settings Scale tab could show `Failed to load Cosmos throughput status` when the configured `SimpleChat` database did not have a database-level `throughputSettings/default` resource. Azure returned a 404 for the database throughput request even though the Cosmos account and containers existed.
+
+## Root Cause Analysis
+
+The first Cosmos throughput implementation assumed the app would always manage database-level shared autoscale throughput. Some environments use dedicated container throughput or a mixed layout, so the database throughput ARM resource can be absent while container throughput resources are valid.

+- Database throughput 404s now return a container-targeted status instead of failing the whole status endpoint.
+- The backend discovers containers and reads each container's dedicated throughput settings.
+- The Scale tab now shows container mode/current RU alongside utilization and request units.
+- Added a Container Throughput Policies modal where admins can configure each container's min/max RU, scale-up/down thresholds, step sizes, cooldowns, and guardrail ignore flags.
+- Manual scale requests can now target a specific container.

+# Cosmos Container Throughput Refresh Performance Fix
+
+Fixed/Implemented in version: **0.241.155**
+
+## Issue Description
+
+Container-targeted Cosmos throughput scaling requires per-container RU utilization. Admins could see per-container `Normalized RU Consumption` in the Azure portal, but SimpleChat still needed to request the same Azure Monitor dimensions and avoid using aggregate account utilization for individual container scale decisions. Refreshes were also slow because the app read each container throughput setting serially, with each ARM request taking hundreds or thousands of milliseconds.
+
+## Root Cause Analysis
+
+The Azure Monitor query needed to match the portal-style split by configured `DatabaseName` and `CollectionName`. Separately, ARM exposes current dedicated throughput through each container's `throughputSettings/default` child resource, so the app still has to read per-container throughput resources. The previous implementation did those reads one after another and acquired ARM credentials for each read.

+

+- Added a database-specific Azure Monitor filter builder: `DatabaseName eq '<database>' and CollectionName eq '*'`.
+- Kept aggregate metrics only as a display fallback for the summary card when container-dimensional metrics lag or are unavailable.
+- Added an explicit `container_metrics_unavailable` no-scale decision when scalable containers lack per-container utilization.
+- Reused a single ARM token/context for container throughput reads during a refresh.
+- Parallelized container throughput reads with a bounded worker pool while preserving container row order and per-container error handling.
+- Clarified Admin Settings messaging that individual container autoscale waits for per-container utilization.
+- Application version updated to `0.241.155` in `application/single_app/config.py`.
+
+## Validation
+
+Test results:
+
+- Python syntax validation for Cosmos throughput helpers and functional tests.

+
+Before/after comparison:

+# Cosmos Native Autoscale Migration Action Fix
+
+## Issue Description
+
+Fixed in version: **0.241.160**
+
+The Admin Settings Scale tab could enable manual-to-Cosmos-autoscale conversion, but the background scheduler and immediate conversion action attempted to update `autoscaleSettings.maxThroughput` directly on an existing manual throughput offer.
+
+Cosmos DB rejected that request with:
+
+```text
+Existing offer needs to be autoscale to be able to update autoscale settings
+```
+
+## Root Cause Analysis
+
+Cosmos DB exposes manual-to-autoscale conversion as a dedicated Azure Resource Manager action:
+
+- `Microsoft.DocumentDB/databaseAccounts/sqlDatabases/throughputSettings/migrateToAutoscale/action`
+- `Microsoft.DocumentDB/databaseAccounts/sqlDatabases/containers/throughputSettings/migrateToAutoscale/action`
+
+A direct `PUT` to `autoscaleSettings.maxThroughput` is valid only after the offer is already in native Cosmos autoscale mode.
+
+## Version Implemented
+
+Fixed in version: **0.241.160**
+
+Related config.py version update: `VERSION = "0.241.160"`
+
+Related deployer version update: `deployers/version.txt` set to `1.0.13`

+- `application/single_app/config.py`
+- `docs/explanation/features/COSMOS_NATIVE_AUTOSCALE_CONVERSION.md`
+
+### Code Changes Summary
+
+- Manual throughput conversion now calls `POST {throughputSettings/default}/migrateToAutoscale`.
+- Existing autoscale offers still use `PUT autoscaleSettings.maxThroughput` for normal RU max updates.
+- The custom SimpleChat Cosmos Throughput Operator role now includes the database and container `migrateToAutoscale/action` permissions plus operation-result read permissions.
+- Regression coverage verifies that manual offers use the migration action and do not send a direct autoscaleSettings `PUT`.
+
+### Impact Analysis
+
+The change preserves the least-privilege model: the app identity can migrate and adjust throughput settings, but it still receives no Cosmos DB data-plane permissions from this custom role.
+
+## Validation
+
+The fix should be validated with:
+
+- Python compilation for changed backend and test files.
+- Focused Cosmos throughput tests.
+- Azure provider operation verification for the custom role actions.
+- Live App Insights traces confirming that the background scheduler no longer records the manual-offer autoscaleSettings `BadRequest`.

+# Cosmos Throughput Access Validation Diagnostics Fix
+
+Fixed/Implemented in version: **0.241.183**
+
+## Issue Description
+
+The Cosmos DB Throughput setup guide did not explicitly tell admins which Azure identity needed RBAC, which role to assign, or where to assign it. When admins clicked **Validate Access**, failures could collapse into a generic `Failed to validate Cosmos throughput access` or `Failed to load Cosmos throughput status` message instead of identifying the missing permission.
+
+## Root Cause Analysis
+
+The status helper allowed database-throughput ARM read failures to escape the status response, so the validation route returned a generic 500. The browser also flattened validation checks into one message and only highlighted failed checks, which made it hard to see what succeeded before the failure.
+
+## Technical Details
+
+Files modified:
+
+- `application/single_app/functions_cosmos_throughput.py`
+- `application/single_app/static/js/admin/admin_settings.js`

+- `functional_tests/test_cosmos_throughput_autoscale_logic.py`
+- `ui_tests/test_admin_cosmos_throughput_settings_ui.py`
+
+Code changes summary:
+
+- Database throughput read failures are now preserved in the status payload as `throughput_error` instead of forcing a generic route failure.
+- Validate Access now reports resource configuration, database throughput read access, scalable target discovery, container discovery, and Azure Monitor metrics as separate pass/fail checks.
+- The Admin Settings alert renders every validation check with safe DOM APIs and includes successful checks for context.
+- The setup guide now names the Azure App Service managed identity service principal, the custom `SimpleChat Cosmos Throughput Operator` role, the recommended assignment scopes, and the required management-plane permissions.
+
+## Validation
+
+Test results:
+
+- Functional tests cover partial ARM and Azure Monitor permission failures without live Azure resources.
+- UI tests cover the explicit setup-guide text and detailed validation-result renderer.
+
+Before/after comparison:
+
+- Before: admins could see only a generic failure and had to inspect logs to infer whether Cosmos throughput, container discovery, or Azure Monitor metrics failed.
+- After: admins see which checks passed, which failed, and the Azure error detail for the failing check.
+
+Related config.py version update:

+# Cosmos Throughput Cached Status Fix
+
+Fixed/Implemented in version: **0.241.152**
+
+## Issue Description
+
+After restarting the server and returning to Admin Settings, the Cosmos DB Throughput card showed no containers until an admin clicked Refresh. This made container-targeted scaling look unavailable even though background automation could still evaluate and scale throughput.
+
+## Root Cause Analysis
+
+Cosmos throughput refreshes and background autoscale checks stored only summary runtime fields such as last checked time, last observed utilization, and last mode. The detailed capacity scope, throughput summary, metrics, and container rows were not persisted for the initial Admin Settings render.

+
+- Added a compact cached Cosmos throughput status containing admin-display-safe resource identifiers, capacity scope, throughput summary, metrics, container rows, errors, and timestamps.
+- Saved the cached status after manual Refresh and background autoscale checks.
+- Rendered the cached status immediately on Admin Settings page load before any live Refresh request.
+- Preserved the last good cached view when an autoscale check fails before producing a usable status.
+- Added Admin Settings copy explaining that automation checks throughput about every 5 minutes while enabled.
+- Added a versioned `admin_settings.js` script URL so browser caching does not keep old Cosmos UI logic after version updates.
+- Application version updated to `0.241.152`.

+## Validation
+
+Test results:
+
+- JavaScript syntax validation for `admin_settings.js`.

+# Cosmos Throughput Container Max Scale Fix
+
+Fixed/Implemented in version: **0.241.194**
+
+## Issue Description
+
+Dedicated Cosmos DB containers could remain at 9,000 RU/s even after crossing the configured scale-up threshold when the configured maximum was 10,000 RU/s and database-level throughput also existed in the account.
+
+## Root Cause Analysis
+
+The autoscale decision path evaluated database throughput first whenever a scalable database throughput target was present. In mixed database and dedicated-container throughput configurations, this could mask a hotter dedicated container candidate. A container at 9,000 RU/s with a 10,000 RU/s maximum could therefore be skipped or the database target could be selected instead of the container target.
+
+## Technical Details
+
+### Files Modified
+
+- `application/single_app/functions_cosmos_throughput.py`
+- `application/single_app/config.py`
+- `functional_tests/test_cosmos_throughput_autoscale_logic.py`
+
+### Code Changes Summary
+
+- Evaluated dedicated container autoscale decisions before applying database-level scale actions when both throughput scopes are present.
+- Preserved the existing fallback to container-only scaling when database throughput is not scalable.
+- Added regression coverage for 9,000 RU/s scaling up to the configured 10,000 RU/s maximum.
+- Bumped `config.py` version to `0.241.194`.
+
+### Testing Approach
+
+- Extended Cosmos throughput functional tests to cover database one-step-to-max scale-up.
+- Added mixed database/container throughput coverage to ensure the hot dedicated container is selected and scaled from 9,000 RU/s to 10,000 RU/s.
+
+## Impact Analysis
+
+Mixed Cosmos throughput deployments now scale the specific dedicated container under pressure instead of letting a database throughput target mask the container action. Existing database-level scaling behavior remains unchanged when no dedicated container needs scaling.

+# Cosmos Throughput Container-Targeted Status Copy Fix
+
+Fixed/Implemented in version: **0.241.184**
+
+## Issue Description
+
+The Admin Settings Cosmos DB Throughput card showed a yellow warning when the configured database did not have database-level throughput and SimpleChat correctly switched to container-targeted throughput. The wording said database-level throughput was not found, which made customers think a supported container-targeted setup was broken.
+
+## Root Cause Analysis
+
+The frontend used warning styling and absence-focused language for the normal `container` capacity scope. That state can be expected when containers have dedicated throughput, so it should be presented as informational unless permissions or per-container metrics fail.
+
+## Technical Details
+
+Files modified:
+
+- `application/single_app/functions_cosmos_throughput.py`
+- `application/single_app/static/js/admin/admin_settings.js`
+- `application/single_app/config.py`
+- `docs/explanation/features/v0.241.147/COSMOS_THROUGHPUT_AUTOSCALE.md`
+- `functional_tests/test_cosmos_throughput_autoscale_logic.py`
+- `ui_tests/test_admin_cosmos_throughput_settings_ui.py`
+
+Code changes summary:
+
+- Changed the normal container-targeted status alert from warning to info.
+- Reworded the message to say container-targeted throughput is active and explain which containers can be scaled.
+- Reworded the Validate Access database-throughput check to avoid “not found” language when dedicated container throughput checks are being used successfully.
+
+## Validation
+
+Test results:
+
+- Functional coverage verifies the neutral Validate Access message for container-targeted throughput mode.
+- UI coverage verifies the new informational frontend copy and guards against the old warning-like text.
+
+Before/after comparison:
+
+- Before: normal container-targeted capacity displayed as a yellow warning and said database-level throughput was not found.
+- After: normal container-targeted capacity displays as informational and says container-targeted throughput is active.

+# Cosmos Throughput Policy Validation Fix
+
+## Issue Description
+
+Fixed in version: **0.241.161**
+
+The Admin Settings Scale tab allowed Cosmos throughput automation settings to be saved with contradictory policy values. For example, an admin could set a Metrics Window longer than the scale-up or scale-down interval, or set Scale Up At to a value lower than or equal to Scale Down At.
+
+## Root Cause Analysis
+
+The backend normalization layer silently repaired invalid policy relationships so runtime automation stayed safe, but the Admin Settings save flow did not reject the invalid input or explain why the values could not work together. The frontend also had no save-blocking validation for these relationships.
+
+## Version Implemented
+
+Fixed in version: **0.241.161**
+
+Related config.py version update: `VERSION = "0.241.161"`
+
+## Technical Details
+
+### Files Modified

+- `application/single_app/config.py`
+- `docs/explanation/features/v0.241.147/COSMOS_THROUGHPUT_AUTOSCALE.md`
+
+### Code Changes Summary
+
+- Added explicit save validation for Cosmos throughput policy relationships.
+- Blocked saves when Scale Up At is not higher than Scale Down At.
+- Blocked saves when Scale Up Interval or Scale Down Interval is smaller than the Metrics Window.
+- Applied the same policy relationship checks to enabled per-container policies when global defaults are not enforced.
+- Grouped Scale Up Policy and Scale Down Policy controls in the Admin Settings Scale tab.
+- Preserved runtime normalization repair behavior for existing saved settings while making new admin saves explicit.
+
+### Testing Approach
+
+- Backend functional tests verify invalid global and per-container policies produce validation errors.
+- UI tests verify the grouped Scale tab sections and validation hooks exist.
+- Syntax checks cover the changed backend route/helper and admin JavaScript.
+
+### Impact Analysis
+
+Admins now get immediate, clear feedback before an invalid Cosmos throughput policy is saved. Automation policy settings are easier to scan because scale-up controls and scale-down controls are grouped separately.
+
+## Validation
+
+The fix should be validated with:
+
+- Python compilation for changed backend and test files.
+- JavaScript syntax validation for Admin Settings.
+- Focused Cosmos throughput functional tests.
+- Focused Admin Settings Cosmos throughput UI tests.

+# Cosmos Throughput Portal-Managed Limit Fix - Version 0.241.199
+
+Fixed/Implemented in version: **0.241.199**
+
+## Issue Description
+
+Cosmos throughput automation could present SimpleChat-managed scaling controls for targets above 10,000 RU/s. Capacity changes above this level can require a long Azure provisioning window, so admins needed clearer guidance that high-throughput targets should be monitored in SimpleChat but changed in the Azure portal.
+
+## Root Cause Analysis
+
+The Cosmos throughput default maximum and policy guardrails previously allowed values above the SimpleChat support ceiling. Backend decisions and admin UI controls did not consistently distinguish between throughput targets SimpleChat can scale directly and higher-capacity targets that should remain monitor-only.
+
+## Technical Details
+
+### Files Modified
+
+- `application/single_app/functions_cosmos_throughput.py`
+- `application/single_app/templates/admin_settings.html`
+- `application/single_app/static/js/admin/admin_settings.js`
+- `functional_tests/test_cosmos_throughput_autoscale_logic.py`
+- `ui_tests/test_admin_cosmos_throughput_settings_ui.py`
+- `application/single_app/config.py`
+
+### Code Changes Summary
+
+- Added a 10,000 RU/s SimpleChat scaling ceiling for Cosmos throughput decisions.
+- Preserved utilization and request-unit monitoring for database or container throughput above 10,000 RU/s.
+- Blocked backend scale and manual-to-autoscale update paths when the current or target throughput requires portal-managed capacity changes.
+- Added portal-managed status metadata so the admin UI can show monitor-only indicators.
+- Updated Admin Settings copy to explain that portal capacity changes above 10,000 RU/s can take 4 to 6 hours.
+- Added a container policy modal filter and prefilled it when opening the modal from a row gear button.
+
+### Testing Approach
+
+- Added functional coverage for 9,000 to 10,000 scale-up, 10,000 scale-up advisory behavior, and >10,000 monitor-only decisions.
+- Added functional coverage to reject manual scale requests for portal-managed targets.
+- Added UI assertions for monitor-only labels, portal copy, the 10,000 maximum input cap, and the container policy modal filter.
+
+### Impact Analysis
+
+SimpleChat continues to scale targets at or below 10,000 RU/s. Throughput above 10,000 RU/s remains visible in Admin Settings for monitoring, but SimpleChat disables scale and conversion controls and instructs admins to use the Azure portal for capacity changes.
+
+## Validation
+
+### Test Results
+
+Focused validation was run against the Cosmos throughput backend logic, admin JavaScript syntax, and Admin Settings UI tests.
+
+### Before/After Comparison
+
+Before this fix, a high-throughput Cosmos target could appear to be SimpleChat-managed and the policy modal required admins to hunt through large container lists. After this fix, high-throughput targets are marked monitor-only, SimpleChat blocks unsupported scaling paths, and row gear buttons open the policy modal filtered to the selected container.
+
+### User Experience Improvements
+
+Admins now see an explicit monitor-only designation for targets above 10,000 RU/s, with clear guidance that Azure portal capacity changes can take 4 to 6 hours. The container policy modal is faster to use because it includes filtering and opens directly to the selected container when launched from a table row.

+Fixed/Implemented in version: **0.241.149**
+
+## Issue Description
+
+The Admin Settings Scale tab could appear stuck on `Loading Cosmos throughput status...` without visible backend logs showing where the refresh request was waiting.
+
+## Root Cause Analysis
+

+- Added a `refresh_id` correlation value so logs from one browser Refresh click can be followed through backend phases.
+- Added ARM request start/completion logs with method, resource kind, status code, elapsed time, and credential acquisition time.
+- Added container-list, container-throughput-scan, Azure Monitor metrics, and overall status refresh timing logs.
+
+## Validation
+
+Test results:

+- Python syntax validation for changed backend modules.
+- Functional source regression test verifies refresh logging markers and correlation fields are present.
+- Existing Cosmos throughput autoscale functional regression test still passes.

+# Cosmos Throughput Table Clarity Fix
+
+Fixed/Implemented in version: **0.241.151**
+
+## Issue Description
+
+The Admin Settings Scale tab showed Cosmos container metrics in a crowded table that mixed database name, RU utilization, and request-unit volume without enough explanation. Admins could confuse request units with utilization percentage, and the text Configure action took unnecessary space in each container row.
+
+## Root Cause Analysis
+
+The container table was originally shaped around database-level throughput and later gained container-targeted scaling. The table still kept the redundant Database column and did not distinguish unavailable Azure Monitor container metrics from a real zero-value metric row.
+
+## Technical Details
+
+Files modified:
+
+- `application/single_app/templates/admin_settings.html`
+- `application/single_app/static/js/admin/admin_settings.js`

+- `application/single_app/config.py`
+- `ui_tests/test_admin_cosmos_throughput_settings_ui.py`
+- `docs/explanation/release_notes.md`
+
+Code changes summary:
+
+- Removed the Database column from the Cosmos container metrics table.
+- Added tooltip explanations for RU Utilization and Request Units.
+- Replaced the visible Configure row action with a gear-only button and accessible label.
+- Added a Cosmos Throughput Setup Guide modal with a Run Test button that reuses the refresh/status check path.
+- Preserved missing Azure Monitor container request-unit metrics as unavailable instead of showing a misleading zero.
+- Application version updated to `0.241.151`.
+
+## Validation
+
+Test results:
+
+- JavaScript syntax validation for `admin_settings.js`.
+- Python syntax validation for `functions_cosmos_throughput.py`.
+- Focused UI regression test for Admin Settings Cosmos throughput controls, setup guide, and compact container table rendering.
+
+Before/after comparison:
+
+- Before: the table included a redundant Database column, unclear metric labels, and a wide Configure text button.
+- After: the table focuses on container, mode, current RU/s, utilization, request-unit volume, policy, and compact actions with explanatory tooltips.

+# CSRF State-Changing Route Guard Fix
+
+Fixed in version: **0.242.053**
+
+## Issue Description
+
+SimpleChat had many state-changing Flask routes using browser session cookies, including admin, workflow, document, collaboration, external public document, and Microsoft 365 pending-action endpoints. These routes did not have an explicit CSRF token, same-origin request validation, or configured session cookie SameSite boundary in the Flask request lifecycle.
+
+## Root Cause Analysis
+
+The application relied on authenticated Flask/Easy Auth sessions and route-level authorization, but ambient browser cookies can be attached automatically to cross-site POST, PUT, PATCH, and DELETE requests. The app also did not define session cookie SameSite defaults in `config.py` or `app.py`.
+
+## Technical Details
+
+Files modified:
+
+- `application/single_app/app.py`
+- `application/single_app/config.py`
+- `functional_tests/test_csrf_state_changing_route_guard.py`
+
+Code changes summary:
+
+- Added explicit session cookie defaults for `SESSION_COOKIE_SAMESITE`, `SESSION_COOKIE_HTTPONLY`, and `SESSION_COOKIE_SECURE`.
+- Added `CSRF_ENFORCE_ORIGIN_FOR_UNSAFE_METHODS` and `CSRF_TRUSTED_ORIGINS` configuration knobs.
+- Added a global before-request guard that checks authenticated POST, PUT, PATCH, and DELETE requests for same-origin browser metadata using `Sec-Fetch-Site`, `Origin`, and `Referer`.
+- Fixed the same-origin browser fetch path so normal in-app `fetch()` calls are allowed even when Azure proxy metadata makes Flask see a different scheme or host than the public browser origin.
+- Covered the GET stream reattach endpoint because it mutates in-memory stream consumer state while keeping the existing fetch-based streaming contract.
+- Included forwarded host/proto, Front Door URL, login/home redirect URLs, and configured trusted origins when resolving allowed origins.
+- Kept non-browser clients without browser origin headers compatible while rejecting browser requests that clearly originate cross-site.
+
+## Validation
+
+Testing approach:
+
+- Added a functional regression test to verify the guard structure, origin-header checks, trusted-origin handling, and explicit session-cookie settings.
+- Ran Python compilation and the focused functional test.
+
+Before/after comparison:
+
+- Before: authenticated unsafe-method routes had no explicit same-origin or CSRF-related boundary in Flask.
+- After: cross-site browser mutations with authenticated sessions are rejected before route handlers run.
+
+Related config.py version update:
+
+- Updated `VERSION` to **0.242.053**.

+# Deep Research Explicit Toggle Fix
+
+Fixed/Implemented in version: **0.241.079**
+
+## Issue Description
+
+Web Search-only chat requests could display Deep Research progress such as "Planning Deep Research web searches" and "Reviewing source pages for supporting evidence" even when the user had not selected Deep Research.
+
+## Root Cause Analysis
+
+The legacy Deep Research default mode `auto_with_web_search` allowed the backend to enable Source Review whenever Web Search was active. Existing saved settings using that mode could make a normal Web Search request inspect source pages automatically.
+
+## Version Implemented
+
+- Application version updated in `application/single_app/config.py` to `0.241.079`.
+
+## Technical Details
+
+### Files Modified
+
+- `application/single_app/functions_source_review.py`
+- `application/single_app/functions_settings.py`
+- `application/single_app/route_backend_chats.py`

+- `functional_tests/test_deep_research_explicit_toggle.py`
+- `functional_tests/test_source_review_security.py`
+- `ui_tests/test_admin_source_review_settings.py`
+
+### Code Changes Summary
+
+- Changed Deep Research default mode to `manual`.
+- Normalized stale saved automatic modes back to `manual`.
+- Removed automatic Deep Research enablement from both streaming and non-streaming chat paths.
+- Updated Admin Settings and setup guide copy to state that Deep Research runs only when the user selects it.
+- Added regression coverage for Web Search-only requests not enabling Deep Research.
+
+### Testing Approach
+
+- Functional test verifies Web Search does not auto-enable Deep Research.
+- Functional test verifies chat routes no longer call the auto-enable helper.
+- UI test expectations were updated for the manual-only activation control.
+
+## Impact Analysis
+
+Users can run plain Web Search without source-page inspection. Deep Research still works when explicitly selected and still respects the existing app-role, runtime, URL safety, page budget, and traversal controls.
+
+## Validation
+
+Run:
+
+```bash
+python functional_tests/test_deep_research_explicit_toggle.py
+python functional_tests/test_source_review_security.py

+# Deep Research JavaScript Rendering Runtime Guard Fix
+
+Fixed in version: **0.241.072**
+
+## Issue Description
+Admins could leave `Allow JavaScript rendering fallback` enabled even when the app runtime reported that Playwright Chromium could not launch. This made the setting appear available while Deep Research would fail or skip rendered-page review at runtime.
+
+## Root Cause
+The Admin Settings page displayed runtime capability details but did not use that capability result to disable the JavaScript rendering setting. The save route also trusted the submitted checkbox value instead of coercing it through the runtime probe.
+
+## Technical Details
+- Added `normalize_source_review_js_rendering_enabled()` in `functions_source_review.py` to require verified `js_rendering_available` runtime support before enabling the setting.
+- Updated `route_frontend_admin_settings.py` so stale stored values render as disabled/off when Chromium cannot launch and POST saves cannot persist the setting as enabled without runtime support.
+- Updated `admin_settings.html` to disable the checkbox and explain that Playwright Chromium must be available before the option can be enabled.
+- Updated `ui_tests/test_admin_source_review_settings.py` and `functional_tests/test_source_review_security.py` for regression coverage.
+- Updated `config.py` version to `0.241.072`.
+
+## Validation
+- Python syntax checks cover the changed Python files and tests.
+- Functional Source Review tests validate that the runtime gate returns false when `js_rendering_available` is false.
+- Admin Settings UI test validates that the checkbox is disabled when runtime support is unavailable and enabled only when the status reports verified Chromium launch support.
+
+## Impact
+Admins can no longer enable Deep Research JavaScript rendering fallback unless the app host can actually launch Playwright Chromium. Existing stale saved values are shown as disabled/off and are coerced off on save until runtime support is available.

+# Deep Research Ledger Source Review Traversal Fix
+
+Fixed in version: **0.241.051**
+
+## Issue Description
+
+The generated Deep Research Ledger showed planned search queries, web-search runs, reviewed pages, and skipped pages, but it did not clearly show the child pages that Deep Source Review followed from a returned seed page. Users could infer that deeper review happened from citations, but the audit artifact did not explain the parent page, child page, depth, or selection reason.
+
+## Root Cause Analysis
+
+Source Review page records already carried traversal metadata such as `parent_url`, `depth`, and `reason`, but `build_deep_research_ledger(...)` discarded those fields when building the compact ledger. `build_deep_research_ledger_markdown(...)` then rendered reviewed and skipped pages as flat lists, losing the deeper path context.
+
+## Version Implemented
+
+Fixed in version: **0.241.051**
+
+## Technical Details
+
+### Files Modified
+
+- `application/single_app/functions_source_review.py`
+- `functional_tests/test_deep_research_query_planning_and_ledger.py`
+- `docs/explanation/features/v0.241.051/DEEP_RESEARCH.md`
+- `application/single_app/config.py`
+
+### Code Changes Summary
+
+- Preserved Source Review traversal fields in Deep Research ledger reviewed/skipped page metadata.
+- Added grouped `source_review_traversal` ledger data for seed pages and their reviewed/skipped child pages.
+- Added a Markdown `Source Review Traversal` section showing parent URL, child URL, depth, selection reason, publish date, skip reason, link count, and Load More activity when available.
+- Fixed skipped-page reason extraction so `skip_reason` values are shown instead of the generic skipped status.
+
+### Testing Approach
+
+- Updated the Deep Research functional test to validate traversal metadata and Markdown output for seed pages, reviewed child pages, skipped child pages, parent URLs, and selection reasons.
+
+## Impact Analysis
+
+Deep Research artifacts are more transparent and auditable. Users can now see where the system went after an initial source page and how Deep Source Review reached detail pages that later appear in citations.
+
+## Validation
+
+### Before
+
+- Reviewed and skipped pages appeared as flat lists.
+- Child pages reached via Source Review did not show their parent page or traversal reason.
+
+### After
+
+- The ledger includes a `Source Review Traversal` section that groups deeper reviewed/skipped pages under their seed or parent URL.
+- Reviewed and skipped page lists include depth and parent information.
+
+## Related Version Updates
+
+- `application/single_app/config.py` was updated to version **0.241.051**.

+Deep Research could plan and review strong source evidence, but time-sensitive requests such as upcoming events, speaking opportunities, interviews, deadlines, or current security topics did not receive an explicit current date.

+## Root Cause Analysis
+
+The standard Semantic Kernel chat path already loads the Time plugin when enabled, but Deep Research performs server-side query planning, Foundry web search calls, and Source Review evidence packaging outside that normal tool-call loop. Those orchestration steps sent the user request and reviewed evidence without a server-provided temporal context.
+
+## Version Implemented
+
+- Application version updated in `application/single_app/config.py` to `0.241.116`.
+
+## Technical Details
+
+### Files Modified
+
+- `application/single_app/functions_source_review.py`
+- `application/single_app/route_backend_chats.py`
+- `functional_tests/test_deep_research_query_planning_and_ledger.py`
+- `application/single_app/config.py`
+
+### Code Changes Summary
+
+- Added reusable research temporal context helpers that expose the current UTC date, time, year, and display date.
+- Added current-date guidance to Deep Research query planning, deterministic fallback query variants, Source Review child-link planning, Source Review evidence system messages, Deep Research ledger metadata, and Deep Research ledger Markdown.
+- Added current-date guidance to the request sent to the external Foundry web-search agent so normal Web Search and Deep Research search calls can interpret relative terms consistently.
+
+### Testing Approach
+
+- Updated the Deep Research functional test to validate current-date query bias for event/speaking opportunities.
+- Added coverage for the web-search prompt temporal context and ledger temporal metadata.
+
+## Impact Analysis
+
+Deep Research and Web Search now have an explicit current-date anchor for time-sensitive requests. Current, recent, upcoming, future, deadline, event, speaking, and participation language is interpreted relative to the server date, reducing stale results being presented as actionable future opportunities.

+# Document Action Conversation Scope Metadata Fix
+
+Fixed in version: **0.241.124**
+
+## Issue Description
+
+Analyze and tabular document-action conversations could complete against group or public workspace documents while the conversation badge and metadata still appeared personal.
+
+## Root Cause Analysis
+
+Document-action execution passes selected or analyzed document summaries into conversation metadata, but the metadata collector only derived workspace context from hybrid search results. Analyze and tabular document actions often do not have hybrid search results, especially when the selected workbook is opened directly by the tabular processing path. When the request scope was `all`, the collector did not have enough evidence to assign group or public primary context.
+
+Streaming document-action responses also normalized the final payload without `context`, `chat_type`, or scope-lock fields, which could leave the live UI stale until a reload.
+
+## Technical Details
+
+Files modified:
+
+- `application/single_app/functions_conversation_metadata.py`
+- `application/single_app/route_backend_chats.py`
+- `application/single_app/config.py`
+- `functional_tests/test_document_action_conversation_scope_metadata.py`
+
+Code changes summary:
+
+- Added selected-document metadata fallback so conversation context can be inferred from document-action analysis summaries when `search_results` is empty.
+- Preserved the assigned-knowledge personal-agent rule so assigned public knowledge remains secondary to a personal primary context.
+- Included document-action `context`, `chat_type`, `scope_locked`, and `locked_contexts` in streaming normalized payloads.
+
+Testing approach:
+
+- Added functional coverage for group selected-document metadata assigning a group primary context.
+- Added regression coverage for personal agents with assigned public knowledge keeping personal primary context.
+- Added static coverage for document-action streaming metadata fields.
+
+## Impact Analysis
+
+Group and public Analyze or tabular document-action turns now update conversation badges and scope lock metadata from the actual analyzed documents. Personal agents with assigned public knowledge continue to show personal conversation context as intended.
+
+## Validation
+
+Run:
+
+```bash
+python functional_tests/test_document_action_conversation_scope_metadata.py
+python -m py_compile application/single_app/functions_conversation_metadata.py application/single_app/route_backend_chats.py

+# Document Action Token Usage Fix
+
+Fixed in version: **0.241.116**
+
+## Overview
+
+Analyze and comparison document actions were not preserving aggregate token usage across their internal model calls.
+This caused large multi-document runs to under-report usage even when the coverage metadata showed hundreds or thousands of processed windows and chunks.
+
+## Root Cause
+
+The document action workflow wrapped every model and agent invocation in an `invoke_prompt` adapter that converted responses directly to strings.
+That adapter dropped `usage`, so analysis and comparison only kept text and coverage, not the cumulative prompt and completion totals from all internal calls.
+
+## Technical Details
+
+Files modified:
+
+- `application/single_app/functions_workflow_runner.py`
+- `application/single_app/route_backend_chats.py`
+- `application/single_app/config.py`
+- `functional_tests/test_document_action_token_usage_aggregation.py`
+
+Code changes summary:
+
+- Added token usage extraction and aggregation helpers in the workflow runner.
+- Aggregated token usage across every internal analysis and comparison model call.
+- Persisted aggregated token usage on workflow and chat assistant message metadata.
+- Logged aggregated document action token usage to activity logs for reporting.
+
+## Validation
+
+Functional test:
+
+- `functional_tests/test_document_action_token_usage_aggregation.py`
+
+Validation approach:
+
+- Verifies analysis token totals are summed across multiple internal invokes.
+- Verifies comparison token totals are summed across multiple internal invokes.
+- Verifies workflow assistant metadata stores the aggregated token usage.
+- Verifies chat document action persistence includes the aggregated token usage field and activity logging call.
+
+## Impact
+
+Before:
+
+- Large analysis and comparison runs could report token usage from only a subset of internal model calls.
+
+After:
+
+- Analyze and comparison runs store and log aggregate prompt, completion, and total tokens for the full document action execution.

+# Document Analysis Answer-First Artifact Preview Fix
+
+Version: 0.241.124
+
+Fixed/Implemented in version: **0.241.124**
+
+Related config.py update: `VERSION = "0.241.124"`
+
+## Header Information
+
+- Issue description: Analyze workflows could successfully produce thorough CSV and Markdown artifacts while the primary assistant message led with artifact bookkeeping and a short preview instead of directly answering the user's request.
+- Root cause analysis: Generated document analysis artifact replies summarized artifact creation first and rendered artifact previews expanded by default, causing supporting evidence to dominate the visible chat response.
+- Version implemented: 0.241.124
+
+## Technical Details
+
+- Files modified: `application/single_app/functions_workflow_runner.py`, `application/single_app/static/js/chat/chat-messages.js`, `application/single_app/static/css/chats.css`, `application/single_app/config.py`, `functional_tests/test_document_analysis_answer_first_artifacts.py`.
+- Code changes summary: Added answer-summary synthesis for generated Analyze replies, including page/count table summarization for search-like requests, collapsed Analyze/Comparison artifact previews behind a native disclosure control, removed inline mini-preview fragments from artifact-backed replies, and made CSV artifact previews render as tabular rows instead of JSON blobs.
+- Testing approach: Added a focused functional contract test that verifies the answer-first backend reply helpers and collapsed generated analysis artifact preview UI are present.
+- Impact analysis: Full CSV/Markdown artifacts remain available for download and auditability, while the visible assistant response now prioritizes the concise answer and keeps bulky previews optional.
+
+## Validation
+
+- Test results: `functional_tests/test_document_analysis_answer_first_artifacts.py` validates backend and UI contracts for the fix.
+- Before/after comparison: Before the fix, artifact cards and previews were the dominant response surface, and CSV artifact previews could appear as JSON arrays. After the fix, the assistant message starts with an explicit answer summary, omits awkward inline table-preview fragments, keeps artifact previews collapsed by default, and renders CSV previews as rows.
+- User experience improvements: Users can quickly see what the analysis found, then open or download detailed artifacts when they need the complete table or audit notes.

+
+Fixed/Implemented in version: **0.241.197**
+
+Related config.py update: `VERSION = "0.241.197"`
+
+## Header Information
+
+- Issue description: Analyze could attach a downloadable JSON artifact whenever the model's final answer happened to be valid JSON, even when the user only asked a normal analysis question.
+- Root cause analysis: Document analysis artifact selection treated parseable JSON text as an implicit request for a JSON file instead of separating structured internal output from user-requested file format.
+- Version implemented: 0.241.197
+
+## Technical Details
+
+- Files modified: `application/single_app/functions_workflow_runner.py`, `application/single_app/config.py`, `functional_tests/test_document_analysis_lossless_artifacts.py`.
+- Code changes summary: Added explicit JSON artifact intent detection, kept JSON artifacts available for prompts that request a JSON file or export, and changed implicit JSON-shaped Analyze and Comparison outputs to use Markdown artifacts when an attachment is needed.
+- Testing approach: Extended the document analysis artifact functional test to verify a plain-English Analyze prompt with JSON-shaped output creates a Markdown artifact, while an explicit JSON file prompt still creates a JSON artifact.
+- Impact analysis: Users no longer receive unexpected JSON downloads for regular Analyze requests, while large or structured analysis output can still be preserved in a downloadable Markdown artifact.
+
+## Validation
+
+- Test results: `functional_tests/test_document_analysis_lossless_artifacts.py` validates the JSON opt-in behavior and version alignment.
+- Before/after comparison: Before the fix, any parseable JSON final answer could become a JSON artifact. After the fix, JSON artifacts require an explicit JSON request; otherwise artifact-backed output uses Markdown.
+- User experience improvements: Analyze answers stay aligned with the user's requested format, and detailed supporting output remains downloadable without implying the user asked for JSON.

+Version: 0.241.023
+
+Fixed/Implemented in version: **0.241.070**
+
+Updated in version: **0.241.023**
+
+Issue description:
+Document analysis failed when ordered chunk retrieval queried Azure Search with scope fields that do not exist on the active index. A personal-workspace analysis could request `group_id`, which caused Azure Search to reject the `$select` clause before any chunks were returned.
+
+Root cause analysis:
+`get_ordered_document_chunks()` used one static select list for personal, group, and public search clients. Each index only exposes its own scope identifier, so cross-scope fields in `$select` caused runtime failures.

+Ordered chunk retrieval now picks the scope-specific field that exists on the active Azure Search index and fills the other scope identifiers from the resolved document record.
+
+Impact analysis:
+This fix applies to both chat and workflow analysis execution because both routes share the same ordered retrieval helper through the common analysis backend path.

+
+## Validation
+
+- Test results: The new regression test verifies that structured analysis returns all expected comment objects, preserves multi-window document consolidation, and keeps global structured-output reduction disabled.

+# Document Auto Metadata Extraction Fix
+
+Fixed in version: **0.241.110**
+
+## Issue Description
+
+Automatic document metadata extraction was inconsistent across upload file types when `enable_extract_meta_data` was enabled. Plain text and several text-like formats could finish chunking without the final AI metadata extraction pass, while other processors ran their own local metadata extraction and then had the final status overwritten by the shared upload dispatcher.
+
+Public workspace audio and video processing also did not preserve public workspace scope consistently when saving searchable chunks, which could prevent public media content from participating correctly in final metadata extraction and later metadata-to-chunk synchronization.
+
+## Root Cause Analysis
+
+Metadata extraction was implemented inside individual file processors instead of as one shared post-processing step. File types whose processors did not include that local extraction block skipped automatic extraction entirely. Processors that did include it could set `Final metadata extracted`, but the dispatcher later replaced the status with generic `Processing complete`.
+
+Public media chunk saving reused personal/group assumptions and did not consistently pass `public_workspace_id` into search chunk creation or metadata propagation.
+
+## Technical Details
+
+Files modified:
+
+- `application/single_app/functions_documents.py`
+- `application/single_app/config.py`
+- `functional_tests/test_document_auto_metadata_extraction_consistency.py`
+
+Code changes summary:
+
+- Added one dispatcher-owned final metadata extraction step after successful chunking for all supported upload file types.
+- Disabled processor-local auto extraction when processors are invoked by the dispatcher to avoid duplicate extraction calls.
+- Preserved final status outcomes such as final metadata extracted, no new metadata, extraction warning, and no indexed content.
+- Passed public workspace scope through video chunk creation, audio transcript chunk creation, blob metadata, and metadata-to-chunk sync.
+- Updated `config.py` from `0.241.109` to `0.241.110` for traceability.
+
+## Testing Approach
+
+Added `functional_tests/test_document_auto_metadata_extraction_consistency.py` to validate the dispatcher-owned metadata flow, final status mapping, public workspace media scope handling, and the version update.
+
+## Impact Analysis
+
+All upload-supported file types now share the same automatic metadata extraction experience when the feature flag is enabled. Existing manual metadata extraction endpoints remain unchanged. Public workspace media files now retain public scope during chunk indexing and metadata synchronization.
+
+## Validation
+
+Before this fix, `.txt`, `.xml`, `.yaml`, `.yml`, `.log`, and `.docm` uploads could finish processing without automatic metadata extraction. After this fix, the dispatcher attempts final metadata extraction for any file type that saved at least one chunk and only skips it when the feature is disabled or no chunks were indexed.

+# Document Search Action Save Fix
+
+Fixed/Implemented in version: **0.241.024**
+
+## Overview
+
+Saving a document-search action could fail in the workspace modal with a raw HTML `404 Not Found` page rendered inside the error banner.
+
+## Root Cause
+
+- The workspace save flow performs an optional pre-save validation call to `/api/plugins/validate`.
+- When that validation endpoint was unavailable in the running app instance, the shared client helper treated the returned HTML 404 page as a plain error string and injected it directly into the modal.
+- The document-search action also needed explicit `document_search` schema aliases so both internal type names (`search` and `document_search`) resolve consistently during save and edit flows.
+
+## Files Modified
+
+- `application/single_app/static/js/plugin_common.js`
+- `application/single_app/static/json/schemas/document_search.definition.json`
+- `application/single_app/static/json/schemas/document_search_plugin.additional_settings.schema.json`
+- `ui_tests/test_workspace_document_search_action_modal.py`
+- `functional_tests/test_document_search_action_save_validation_fallback.py`
+
+## Technical Details
+
+1. Added a validation fallback in the shared plugin client helper so a missing `/api/plugins/validate` endpoint no longer blocks save.
+2. Prevented raw HTML error pages from being surfaced directly in the modal by normalizing HTML API responses into concise messages.
+3. Added `document_search` schema aliases so auth-type lookup and additional-settings resolution work even when the UI or persisted manifest uses `document_search` instead of `search`.
+4. Extended the document-search modal UI test to verify save succeeds even when the validation endpoint returns 404.
+
+## Validation
+
+- Targeted functional regression test passes for the validation fallback contract.
+- The document-search UI modal regression test covers the save path with a mocked 404 validation response.
+- Existing document-search functional tests continue to pass.

+# Document Upload Settings Binding Fix
+
+Fixed/Implemented in version: **0.241.101**
+
+## Issue Description
+
+Valid document uploads could fail in two stages after full application startup:
+
+- The upload request could return a 400 even though the file type and request payload were valid.
+- After the request path was repaired, background processing could still fail with `name 'get_settings' is not defined` while generating embeddings.
+
+This affected personal, group, and public workspace uploads because all three flows share the same upload helpers.
+
+Related config update: `application/single_app/config.py` now sets `VERSION = "0.241.101"`.
+
+## Root Cause Analysis
+
+- `application/single_app/functions_logging.py` and `application/single_app/functions_content.py` depended on `get_settings()` through star-import snapshots from `functions_settings.py`.
+- During the full Flask app import path, those snapshots could lose the live `get_settings` binding.
+- The request-time upload logging helper then raised `NameError`, which surfaced as the immediate 400 upload failure.
+- The embedding helper hit the same missing name later in background processing, so uploads could appear accepted but never finish processing.
+
+## Technical Details
+
+Files modified:
+
+- `application/single_app/functions_logging.py`
+- `application/single_app/functions_content.py`
+- `application/single_app/functions_documents.py`
+- `application/single_app/config.py`
+- `functional_tests/test_upload_settings_import_order_fix.py`
+
+Code changes summary:
+
+- Resolved settings access in the upload logging path through the live `functions_settings` module object.
+- Added the same runtime-safe settings resolution to the embedding helper used during background chunk processing.
+- Kept `functions_documents.py` on the same runtime-safe settings access pattern for the shared upload pipeline.
+- Added a focused regression test that imports the full app and exercises both helpers without calling external Azure services.
+
+Testing approach:
+
+- Reproduced the original request-path failure with `functional_tests/test_upload_diagnosis.py`.
+- Re-ran the same diagnostic after the request-path fix to isolate the remaining background embedding failure.
+- Added a focused import-order regression test for the upload logging and embedding helper bindings.
+
+## Validation
+
+Before:
+
+- `/api/documents/upload` could return 400 for valid uploads.
+- Background document processing could fail with `name 'get_settings' is not defined` during embedding generation.
+- The same bug class affected personal, group, and public uploads because they all share the same helper path.
+
+After:
+
+- Upload requests return 200 for valid files.
+- Background processing completes chunk save and embedding generation.
+- The diagnostic upload completed with the document processed successfully and embedding token usage recorded.

+# Enhanced Citations Blob And Collaboration Fix
+
+Fixed/Implemented in version: **0.241.048**
+
+## Issue Description
+
+Enhanced citations regressed in two visible ways after the recent inline visualization changes:
+
+1. Tabular previews started returning HTTP 500 for blob-backed CSV and XLSX citations, so the modal could only show the download fallback instead of the in-browser preview.
+2. Agent citation artifacts inside collaborative conversations started returning `Conversation not found`, which prevented inline Azure Maps artifacts from hydrating and left repeated 404 errors in the browser console.
+3. Agent citation links and inline artifact hydration depended on the active chat conversation id instead of the message’s own conversation context, which made artifact lookups more fragile whenever messages were rendered outside the standard single-user flow.
+
+## Root Cause Analysis
+
+- The enhanced citations route still defined helper logic that rebuilt blob paths locally, but the newer document revision model now relies on persisted blob metadata from `get_document_blob_storage_info(...)` so archived and current-alias citations resolve consistently.
+- The tabular preview path and the shared content-serving path both depended on that stale helper flow, which broke once the direct helper import disappeared from the route.
+- Collaborative conversations mirror compact agent citation records, but the full externalized artifact payload still lives in the hidden source conversation stored in the standard chat containers.
+- The frontend renderer attached the current active conversation id to agent citation links instead of the message-scoped conversation id, which made artifact hydration overly dependent on global state.
+
+## Files Modified
+
+1. `application/single_app/route_enhanced_citations.py`
+2. `application/single_app/route_frontend_conversations.py`
+3. `application/single_app/static/js/chat/chat-messages.js`
+4. `functional_tests/test_enhanced_citations_blob_and_collaboration_fix.py`
+5. `application/single_app/config.py`
+
+## Code Changes Summary
+
+1. Added a shared `_resolve_document_blob_reference(...)` helper in the enhanced citations route so preview and content endpoints resolve persisted blob references through `get_document_blob_storage_info(...)`.
+2. Removed the stale route-local blob path reconstruction logic that could diverge from the current document revision storage model.
+3. Updated the agent citation artifact endpoint to recognize collaborative conversations, validate collaboration access, and read artifact payloads from the hidden source conversation when needed.
+4. Added a message-scoped conversation id resolver in the chat renderer so agent citation links and inline Azure Maps hydration use the correct conversation context instead of only relying on global selection state.
+5. Added a focused functional regression covering persisted blob references, collaboration artifact hydration, message-scoped conversation ids, and the shipped version/documentation alignment.
+
+## Testing Approach
+
+1. Added `functional_tests/test_enhanced_citations_blob_and_collaboration_fix.py` to lock in the backend and frontend regression markers for this fix.
+2. Planned validation includes running the focused functional regression and checking diagnostics for the touched Python and JavaScript files.
+
+## Validation
+
+### Before
+
+1. `/api/enhanced_citations/tabular_preview` could return HTTP 500 for blob-backed tabular citations.
+2. Blob-backed enhanced citations could fall back to text or download-only behavior because the route was no longer resolving the persisted blob metadata helper.
+3. Collaborative agent citation artifacts could 404 even when the source payload existed.
+
+### After
+
+1. Tabular preview and direct enhanced citation rendering resolve persisted blob references consistently for current and historical document revisions.
+2. Collaborative conversations can hydrate externalized agent citation artifacts through the hidden source conversation backing store.
+3. Agent citation links and inline artifact hydration use the message’s conversation context, reducing reliance on whichever chat is currently active.

+# External Browser Asset CSP Allowlist Fix
+
+Fixed/Implemented in version: **0.242.053**
+
+## Issue Description
+
+The external browser assets audit found that the main application Content Security Policy still allowed `https://cdn.jsdelivr.net` in `script-src` and `style-src`, even though SimpleChat browser runtime JavaScript and JavaScript companion assets are expected to be served from local static files.
+
+## Root Cause Analysis
+
+The OpenLayers local asset fix had already moved chat map runtime assets into SimpleChat static files and added regression coverage for local-only CSP behavior. The live CSP later drifted back to permitting jsDelivr script and style sources, leaving a public CDN execution path available to reachable application pages.
+
+## Version Implemented
+
+- **0.242.053**
+- Application version updated in `application/single_app/config.py` to `0.242.053`.
+
+## Files Modified
+
+- `application/single_app/config.py`
+- `functional_tests/test_chat_local_openlayers_assets.py`
+- `docs/explanation/fixes/EXTERNAL_BROWSER_ASSET_CSP_ALLOWLIST_FIX.md`
+- `docs/explanation/fixes/index.md`
+
+## Code Changes Summary
+
+- Removed `https://cdn.jsdelivr.net` from `script-src` and `style-src` in the main application CSP.
+- Removed stale commented CDN allowlist examples beside the active CSP definition.
+- Updated the existing local OpenLayers/CSP regression test to pin the current application version.
+
+## Testing Approach
+
+- Reused `functional_tests/test_chat_local_openlayers_assets.py` to validate local OpenLayers references, local-only script/style CSP fragments, and SimpleMDE CDN-prevention defaults.
+- Ran the repository XSS sink checker against the changed Python file.
+
+## Impact Analysis
+
+- Reachable application pages no longer permit runtime JavaScript or JavaScript-required stylesheets from jsDelivr through the main CSP.
+- Existing local static assets for Bootstrap, Bootstrap Icons, jQuery, DataTables, marked, DOMPurify, Chart.js, SimpleMDE, and OpenLayers remain the browser runtime sources.
+- `unsafe-eval` remains unchanged because the vendored Swagger UI bundle still contains dynamic evaluation patterns and needs a separate compatibility review before tightening.
+
+## Validation
+
+- Before: the active CSP allowed `https://cdn.jsdelivr.net` for scripts and styles.
+- After: the active CSP keeps script and style sources local-only, while authenticated API, Azure service, image, media, and websocket allowances are unchanged.

+# File Sync Admin Discovery Fix
+
+Fixed/Implemented in version: **0.241.052**
+
+## Issue Description
+
+The File Sync backend and workspace Sync tabs existed, but admins could not discover or manage the capability from Admin Settings, and the sidebar did not expose File Sync navigation entries.
+
+## Root Cause Analysis
+
+The File Sync implementation added service, API, scheduler, and workspace tab wiring, but the admin settings template, admin settings save path, and sidebar partial were missing the corresponding controls and links.
+
+## Technical Details
+
+### Files Modified
+
+- `application/single_app/config.py`

+- `functional_tests/test_file_sync_capability.py`
+- `ui_tests/test_admin_file_sync_settings.py`
+
+### Code Changes Summary
+
+- Added File Sync to the Admin Settings Workspaces sidebar section.
+- Added personal and group workspace sidebar links that open the Sync tab when File Sync is enabled for the active workspace.
+- Added an Admin Settings File Sync card with global enablement, per-scope enablement, allow/block lists, run limits, default remote delete policy, and debug logging.
+- Added Redis readiness warnings so admins can save requested settings while File Sync remains inactive until Redis is configured.
+- Added admin save handling for every File Sync settings field.
+
+## Validation
+
+- Added functional regression checks for admin settings, route save handling, sidebar discovery, and File Sync UI visibility wiring.
+- Added an Azure Playwright UI smoke test for the Admin Settings File Sync controls.
+- Updated `config.py` to version `0.241.052` for traceability.

+# File Sync Cloud Connector Visibility Fix
+
+Fixed/Implemented in version: **0.241.178**
+
+## Issue Description
+
+OneDrive, SharePoint, and Google Workspace File Sync connector options were visible as configurable Admin Settings source-type toggles before the connectors had completed validation. This could let admins expose cloud connector choices before the team was ready to support them broadly.
+
+## Root Cause Analysis
+
+The admin-visible source type list used the same setting path as fully available File Sync providers. OneDrive was also present in the default visible source type list, so new or legacy settings could expose it even when admins should only be able to enable the current File Sync and Azure Files paths.
+
+## Version Implemented
+
+- Fixed in version: **0.241.178**
+- Related config version update: `application/single_app/config.py` uses `VERSION = "0.241.178"`.
+
+## Technical Details
+
+- Files modified:
+  - `application/single_app/functions_file_sync.py`
+  - `application/single_app/functions_settings.py`
+  - `application/single_app/templates/admin_settings.html`

+  - `application/single_app/templates/workspace.html`
+  - `application/single_app/templates/group_workspaces.html`
+  - `application/single_app/templates/manage_public_workspace.html`
+- Code changes summary:
+  - Added a server-side admin-visible source type allowlist for SMB Share and Azure Files.
+  - Removed OneDrive from File Sync visible source type defaults while keeping provider code in place.
+  - Rendered OneDrive, SharePoint, and Google Workspace controls as disabled coming-soon options in Admin Settings.
+  - Updated frontend fallback visible source types to avoid exposing OneDrive when a root omits `data-visible-source-types`.
+- Testing approach:
+  - Updated File Sync functional tests for defaults, server-side allowlisting, and disabled admin controls.
+  - Updated the Admin File Sync UI test to assert cloud connectors are visible but disabled.
+
+## Impact Analysis
+
+Admins can still enable File Sync and choose SMB Share or Azure Files as visible source types. OneDrive, SharePoint, and Google Workspace remain visible as coming soon, but they cannot be enabled from Admin Settings or submitted through the standard admin form.
+
+## Validation
+
+- Before: OneDrive could be included in `file_sync_visible_source_types` by default or through Admin Settings.
+- After: Admin Settings only submits SMB Share and Azure Files source type values, and backend normalization filters cloud connector values out of saved visibility settings.
+- User experience improvement: Admins see cloud connector status clearly without being able to turn those connectors on prematurely.

+# File Sync Document Indicator Fix
+
+Fixed in version: **0.241.053**
+
+## Issue Description
+
+Synced files were stored with `file_sync` metadata, but workspace document views did not show any visible system indicator. Users could not tell whether a document came from File Sync without inspecting backend data, and using a normal tag for this would have polluted tag folders and filters.
+
+## Root Cause Analysis
+
+File Sync correctly persisted source metadata on synced documents, but the personal, group, and public workspace renderers only displayed classification, citation, and user tag badges. Metadata modals also omitted a read-only sync status field.
+
+## Version Implemented
+
+Implemented in version: **0.241.053**
+
+Related version update: `application/single_app/config.py` was incremented from `0.241.052` to `0.241.053`.
+
+## Technical Details
+
+### Files Modified
+
+- `application/single_app/static/js/workspace/workspace-utils.js`
+- `application/single_app/static/js/workspace/workspace-documents.js`
+- `application/single_app/static/js/workspace/workspace-tags.js`

+- `application/single_app/templates/public_workspaces.html`
+- `functional_tests/test_file_sync_capability.py`
+- `ui_tests/test_workspace_file_sync_ui.py`
+
+### Code Changes Summary
+
+- Added non-filtering `Synced` system badges based on `doc.file_sync`, not `doc.tags`.
+- Displayed sync badges in document card views, table list views, and folder drill-down document tables.
+- Added read-only metadata modal status blocks showing `Synced: Yes` or `Synced: No`.
+- Added expanded details rows that show synced status, source, and remote path when available.
+- Updated regression tests to verify the indicator wiring is present and not tied to tag metadata.
+
+### Testing Approach
+
+- Functional tests validate that sync indicator helpers and template hooks are present across personal, group, and public workspace surfaces.
+- UI test coverage mocks a synced personal document and verifies the list badge and metadata modal sync status.
+
+## Impact Analysis
+
+The indicator is visual only and does not alter document filtering, tags, sync scheduling, or delete semantics. Synced state remains sourced from the existing `file_sync` document metadata written by the File Sync service.
+
+## Validation
+
+### Before
+
+Synced documents looked identical to normal uploaded documents unless users inferred state from backend records.
+
+### After
+
+Synced documents show a highlighted `Synced` badge in card and list views, and metadata/details views show `Synced: Yes` with source details when available.
+
+### User Experience Improvements
+
+- Users can identify synced files immediately.
+- Sync status is separated from user tags, so synced files do not appear as artificial tag folders.
+- Metadata views now provide explicit yes/no sync status for clarity.

+# File Sync Stale Source Document Delete Fix
+
+Fixed in version: **0.241.054**
+
+## Issue Description
+
+Documents created by File Sync could remain after their sync source was deleted. When users tried to delete those remaining documents, the first delete confirmation was followed by a synced-document confirmation, and the delete flow could stop after the initial `409 CONFLICT` response.
+
+## Root Cause Analysis
+
+The frontend reused the same Bootstrap delete modal for the normal delete confirmation and the synced-document confirmation. The first prompt resolved immediately on button click while the modal was still hiding, so the synced-document prompt could be attached before the previous `hidden.bs.modal` event completed.
+
+The backend also treated any document with `file_sync` metadata as actively synced, even when the original sync source had been deleted. Selecting the ignore-remote action could then try to update a missing source.
+
+## Version Implemented
+
+Implemented in version: **0.241.054**
+
+Related version update: `application/single_app/config.py` was incremented from `0.241.053` to `0.241.054`.

+- `functional_tests/test_file_sync_capability.py`
+- `ui_tests/test_workspace_file_sync_ui.py`
+
+### Code Changes Summary
+
+- Delete modal prompts now resolve only after the modal has fully hidden, preventing the synced-document prompt from being canceled by the previous modal transition.
+- Synced-document delete guards now verify that the File Sync source still exists before requiring the synced-document action prompt.
+- Ignore-remote delete handling now tolerates a deleted sync source and continues with document deletion.
+
+### Testing Approach
+
+- Functional tests validate the modal sequencing pattern and stale-source guard behavior.
+- Existing File Sync wiring tests continue to validate delete guard registration across personal, group, and public routes.
+
+## Impact Analysis
+
+Users can delete documents that were formerly synced after the sync source has been removed. Active synced sources still prompt users to choose whether the remote path should be ignored before deleting the local document.
+
+## Validation
+
+### Before
+
+Deleting a stale synced document could stop after a `409 CONFLICT`, leaving the document in place.
+
+### After
+
+Documents whose sync source no longer exists use the normal delete flow, and active synced documents can complete the second synced-delete confirmation without being canceled by modal timing.

+# File Upload and Document Ingestion Security Audit Fix
+
+Fixed in version: **0.242.054**
+
+## Issue Description
+
+The file upload and document ingestion security audit found several trust-boundary gaps across external public document APIs, citation rendering, and document download headers.
+
+External public document routes accepted `user_id` and `active_workspace_id` directly from request parameters and used them for public workspace upload, metadata update, delete, metadata extraction, and legacy upgrade operations. Citation parsing also constructed inline HTML from document-derived filenames, page/sheet labels, and citation identifiers. Enhanced citation download responses interpolated raw document filenames into `Content-Disposition` headers.
+
+## Root Cause Analysis
+
+The external public routes were designed for the bulk uploader service principal and did not revalidate that the submitted acting user had a manager role in the submitted public workspace before mutating documents. The citation parser produced HTML strings before browser rendering and escaped only some attribute values. Download helpers trusted stored filenames when building response headers.
+
+## Version Implemented
+
+Implemented in version: **0.242.054**
+
+The application version was updated in `application/single_app/config.py` from `0.242.053` to `0.242.054` for this security fix.
+
+## Technical Details
+
+Files modified:
+
+- `application/single_app/route_external_public_documents.py`
+- `application/single_app/route_enhanced_citations.py`
+- `application/single_app/static/js/chat/chat-citations.js`
+- `application/single_app/config.py`
+- `functional_tests/test_file_upload_document_ingestion_security_audit.py`
+
+Code changes summary:
+
+- Added a shared external public workspace context validator that requires `user_id` and `active_workspace_id`, confirms the workspace exists, verifies the acting user's public workspace role, and checks workspace status before route operations.
+- Required public workspace manager roles for external upload, metadata patch, delete, metadata extraction, and legacy upgrade operations while preserving public reader behavior for list/get routes.
+- Built citation anchors with DOM APIs so filenames, location labels, page/sheet labels, and citation IDs are assigned through `textContent`, `dataset`, and normalized URL properties instead of dynamic HTML attributes.
+- Sanitized external citation filename URLs with the existing browser URL helper before assigning `href` values.
+- Added a common enhanced citation `Content-Disposition` builder using sanitized ASCII fallbacks plus RFC 5987 `filename*` encoding.
+
+## Testing Approach
+
+Regression coverage was added in `functional_tests/test_file_upload_document_ingestion_security_audit.py` to validate:
+
+- External public document route functions call the shared public workspace authorization validator.
+- External mutation routes require public workspace manager roles.
+- Citation HTML construction uses escaping and URL sanitization for document-derived values.
+- Enhanced citation download responses use the safe `Content-Disposition` helper.
+- The version bump and fix documentation exist for traceability.
+
+## Impact Analysis
+
+The fix preserves existing personal, group, and public workspace behavior while hardening the external bulk-upload API boundary. Public workspace reads remain available through the existing public reader role model, but document mutations now require the submitted acting user to be an Owner, Admin, or DocumentManager for the target public workspace.
+
+Citation links continue to render and open enhanced citations, but malicious filenames, sheet names, page labels, or crafted citation IDs are assigned through inert DOM text and data properties. Downloaded files retain user-friendly names through encoded filename metadata without exposing raw control characters or header-breaking characters.
+
+## Validation
+
+Expected validation commands:
+
+```powershell
+python -m py_compile application/single_app/route_external_public_documents.py application/single_app/route_enhanced_citations.py application/single_app/config.py functional_tests/test_file_upload_document_ingestion_security_audit.py
+node --check application/single_app/static/js/chat/chat-citations.js
+python functional_tests/test_file_upload_document_ingestion_security_audit.py
+python scripts/check_broken_access_control.py --full-file application/single_app/route_external_public_documents.py application/single_app/route_enhanced_citations.py
+python scripts/check_xss_sinks.py --full-file application/single_app/static/js/chat/chat-citations.js application/single_app/route_enhanced_citations.py
+git -c core.whitespace=blank-at-eol,blank-at-eof,space-before-tab,cr-at-eol diff --check
+```
+
+Before the fix, external public document mutations could proceed from request-supplied workspace/user IDs without route-level role validation, and document-derived citation/header strings crossed into sensitive sinks with incomplete escaping. After the fix, these paths have explicit validation or sanitization at the sensitive operation boundary.

+# Foundry Agent and Workflow API-Key Auth Fix
+
+Fixed/Implemented in version: **0.241.191**
+
+Superseded in version: **0.241.196**
+
+> Current behavior: Foundry agent and workflow invocation now requires Microsoft Entra ID/RBAC. API-key authentication remains supported for model endpoint inference, but is no longer used for chat-selectable New Foundry applications or Foundry Workflow agents. See `FOUNDRY_AGENT_WORKFLOW_ENTRA_AUTH_BOUNDARY_FIX.md`.
+
+## Issue Description
+
+Saved Azure AI Foundry model endpoints already supported API-key authentication for OpenAI-compatible GPT model calls, but Foundry agents and workflows always used delegated user access. Users with a Foundry project key could expose GPT models from that project, but could not use the same saved project connection or a manual project key to run Foundry applications and workflows.
+
+## Root Cause Analysis
+
+The Foundry agent/workflow runtime treated every non-managed-identity or non-service-principal configuration as delegated user authentication. Discovery and invocation paths built bearer-token headers directly, endpoint hydration did not propagate API-key auth from saved model endpoint connections, and the agent modal had no manual key field for users entering Foundry project details directly. The first API-key implementation also sent the project key as both `Authorization: Bearer ...` and `api-key`, which could make Foundry evaluate workflow conversation/action calls as identity/RBAC calls instead of key-backed calls.
+
+## Version Implemented
+
+- Application version updated in `application/single_app/config.py` from `0.241.190` to `0.241.191` for API-key header correction.
+
+## Technical Details
+
+### Files Modified
+
+- `application/single_app/foundry_agent_runtime.py`
+- `application/single_app/semantic_kernel_loader.py`
+- `application/single_app/route_backend_models.py`
+- `application/single_app/functions_keyvault.py`

+- `application/single_app/templates/_agent_modal.html`
+- `application/single_app/config.py`
+- `functional_tests/test_foundry_delegated_user_auth.py`
+
+### Code Changes Summary
+
+- Added API-key credential handling for OpenAI-compatible Foundry REST calls.
+- Reused the shared REST header builder for new Foundry application invocation, streaming, workflow streaming, and application discovery.
+- Propagated saved model endpoint API-key auth into new Foundry application and workflow settings during server-side endpoint hydration.
+- Updated agent creation payloads to save `authentication_type: "api_key"` for new Foundry applications and workflows when the selected saved endpoint uses API-key auth, without storing the key in agent settings.
+- Added a manual Foundry Project API Key field for new Foundry applications and workflows when project details are entered directly.
+- Stored manual agent-level Foundry API keys through the existing Key Vault agent secret helper and resolved them only for runtime.
+- Corrected API-key REST headers to send only `api-key` for key-backed Foundry runtime calls, avoiding accidental identity/RBAC evaluation from a bearer-style key header.
+- Kept classic SDK-based Foundry agents on delegated/token-based authentication because the current Azure AI Projects SDK path expects an async token credential.
+
+### Testing Approach
+
+- Extended the Foundry delegated-auth functional regression test to verify API-key auth resolution, key-only REST header construction, endpoint hydration, backend discovery settings, modal payload behavior, manual API-key entry, agent-level Key Vault handling, and version documentation traceability.
+
+## Impact Analysis
+
+Users can now use either a saved API-key-backed Foundry project connection or a manually entered project API key for OpenAI-compatible Foundry applications and workflows, matching the existing key-based model endpoint capability. Delegated user auth remains the default and classic Foundry agent SDK behavior remains token-based.

+# Foundry Agent and Workflow Entra Auth Boundary Fix
+
+Fixed/Implemented in version: **0.241.196**
+
+## Issue Description
+
+Foundry application agents and Foundry Workflow agents could inherit API-key authentication from saved model endpoints or manual agent settings. That made SimpleChat attempt API-key invocation for Foundry agents/workflows even though current Foundry agent and Agent Application invocation paths require Microsoft Entra ID/RBAC.
+
+## Root Cause Analysis
+
+SimpleChat blurred two different authentication surfaces: API-key model endpoint inference and Foundry agent/workflow invocation. Saved `new_foundry` and `foundry_workflow` model endpoints with `auth.type = api_key` were promoted into chat-selectable agent runtime settings, and the modal exposed a manual Foundry Project API Key field. The workflow runtime also had a fallback that routed API-key workflow configurations through the application protocol.
+
+## Technical Details
+
+### Files Modified
+
+- `application/single_app/foundry_agent_runtime.py`
+- `application/single_app/semantic_kernel_loader.py`
+- `application/single_app/route_backend_models.py`
+- `application/single_app/functions_agent_payload.py`
+- `application/single_app/functions_keyvault.py`

+- `functional_tests/test_foundry_delegated_user_auth.py`
+- `functional_tests/test_foundry_workflow_agent_payload.py`
+- `ui_tests/test_agent_modal_foundry_workflow.py`
+
+### Code Changes Summary
+
+- Restricted Foundry agent and workflow invocation to Microsoft Entra ID/RBAC auth.
+- Preserved API-key support for model endpoint inference through the model endpoint client path.
+- Stopped saved API-key model endpoint auth from being promoted into New Foundry or Foundry Workflow agent runtime settings.
+- Removed the manual Foundry Project API Key field from the agent modal.
+- Stripped `api_key` and `key` from Foundry agent and workflow payloads before storage.
+- Removed agent-level Key Vault registration for New Foundry and Foundry Workflow API keys.
+- Removed the workflow API-key application-protocol fallback.
+
+## Validation
+
+Run:
+
+```bash
+python functional_tests/test_foundry_delegated_user_auth.py
+python functional_tests/test_foundry_workflow_agent_payload.py
+python -m pytest ui_tests/test_agent_modal_foundry_workflow.py
+node --check application/single_app/static/js/agent_modal_stepper.js

+```
+
+## Impact Analysis
+
+Users can continue using API-key saved model endpoints for normal model inference. Chat-selectable Foundry agents and workflows now require signed-in user, managed identity, or service principal access with the appropriate Foundry RBAC permissions. In commercial Foundry, use the renamed role names such as `Foundry User`; in Azure Government and custom clouds, use the equivalent role name shown in the portal, which may still be `Azure AI User`. Web Search configuration remains isolated and unchanged.

+# Foundry Auth-Required Stream Message Fix
+
+Fixed/Implemented in version: **0.241.186**
+
+## Issue Description
+
+When a signed-in user needed Azure AI Foundry consent or access during a Foundry agent or workflow run, the chat stream failed with a generic Microsoft 365 consent message. The chat alert also discarded the structured `auth_url` and `consent_url` fields emitted by the backend, so the user saw a stream interruption without an actionable Foundry sign-in or consent link.
+
+## Root Cause Analysis
+
+Foundry delegated auth reused the shared plugin token helper, whose consent-required fallback text is written for Microsoft 365 plugins. The Foundry runtime passed that generic helper message through unchanged. On the client side, `chat-streaming.js` only passed the `error` string into the stream error renderer and interpolated it into an HTML alert, which prevented the Foundry-specific auth metadata from being displayed safely.
+
+## Version Implemented
+
+- Application version updated in `application/single_app/config.py` from `0.241.185` to `0.241.186`.
+
+## Technical Details
+
+### Files Modified
+
+- `application/single_app/foundry_agent_runtime.py`
+- `application/single_app/static/js/chat/chat-streaming.js`
+- `application/single_app/config.py`
+- `functional_tests/test_foundry_delegated_user_auth.py`
+
+### Code Changes Summary
+
+- Added a Foundry-specific delegated auth-required message for agents and workflows.
+- Preserved the shared MSAL helper's consent URL, auth URL, and scope metadata while replacing only the generic Microsoft 365-facing message.
+- Updated the chat streaming client to carry auth-required metadata from both SSE error events and non-OK JSON stream responses.
+- Rendered the stream error banner with DOM APIs and `textContent`, and normalized the auth URL before assigning it to a link.
+
+### Testing Approach
+
+- Extended the Foundry delegated auth functional regression test to verify the Foundry-specific message, structured stream metadata handling, safe banner rendering, and version/fix documentation traceability.
+
+## Impact Analysis
+
+Users who need Foundry access during a chat run now see Foundry-specific guidance and a safe link to sign in or grant access. Microsoft 365 plugin consent messaging remains unchanged because the override is scoped to the Foundry runtime.

+# Foundry Delegated User Auth Fix
+
+Fixed/Implemented in version: **0.241.185**
+
+## Issue Description
+
+Foundry agents and workflows could work locally but fail after deployment to Azure App Service because the server-side runtime used the host identity. Local development resolved to the developer's Azure credentials, while App Service resolved to the app's managed identity. That made Foundry access app-wide unless the app identity had access, instead of enforcing each signed-in user's Foundry permissions.
+
+## Root Cause Analysis
+
+The Foundry runtime built credentials with Azure Identity defaults unless a service principal was configured. Saved Foundry model endpoint authentication also flowed into agent runtime settings, so model endpoint connectivity and Foundry agent/workflow authorization were coupled. The product requirement is different: model endpoint inference remains app/configured auth, but Foundry agents and workflows should use delegated signed-in user access.
+
+## Version Implemented
+
+- Application version updated in `application/single_app/config.py` from `0.241.184` to `0.241.185`.
+
+## Technical Details
+
+### Files Modified
+
+- `application/single_app/foundry_agent_runtime.py`
+- `application/single_app/semantic_kernel_loader.py`
+- `application/single_app/route_backend_models.py`
+- `application/single_app/route_backend_chats.py`

+- `ui_tests/test_agent_modal_foundry_workflow.py`
+- `ui_tests/test_agent_modal_dual_foundry_modes.py`
+
+### Code Changes Summary
+
+- Added delegated user token support for Foundry agents and workflows using the existing MSAL token helper with the Azure AI Foundry scope.
+- Made Foundry agent/workflow runtime auth default to `delegated_user`, while preserving explicit `managed_identity` and `service_principal` advanced modes.
+- Prevented saved model endpoint managed identity or service principal settings from implicitly becoming Foundry agent/workflow runtime credentials.
+- Updated Foundry discovery and chat streaming error contracts to return `auth_required`, `auth_url`, `consent_url`, and scope information when the user needs consent or sign-in.
+- Updated the agent modal copy, saved payloads, and discovery error rendering to reflect signed-in user Foundry access.
+
+### Testing Approach
+
+- Added a functional regression test that verifies delegated auth defaults, endpoint auth separation, structured auth-required responses, and modal payload/link contracts.
+- Updated UI coverage for the Foundry modal text and auth-required discovery link.
+
+## Impact Analysis
+
+Foundry agents and workflows now follow each signed-in user's Azure AI Foundry permissions by default. Users without Foundry access receive a sign-in or consent path instead of silently depending on the App Service identity. In commercial Foundry, grant the user `Foundry User` or another appropriate renamed Foundry role. In Azure Government and custom clouds, the equivalent role may still appear under its earlier Azure AI role name. Model endpoint inference remains separate and continues to use its configured endpoint authentication.

+# Foundry Model Endpoint Protocol Selection Fix
+
+Fixed in version: **0.241.179**
+
+## Issue Description
+
+New Foundry model endpoints could be configured with Claude deployments, but runtime chat and model connection tests still used the Azure OpenAI client shape with an `api-version` query. Claude deployments require the Anthropic messages protocol, so those calls failed with API version compatibility errors.
+
+Editing an existing API-key-backed endpoint also required the API key field to be filled again, even when the key was already stored securely and the user was only changing model metadata such as name or description.
+
+## Root Cause Analysis
+
+The multi-endpoint runtime selected the client from the configured provider only. Foundry and New Foundry endpoints were treated as Azure OpenAI-compatible even when the deployment name or endpoint path indicated Anthropic. New Foundry `/openai/v1` endpoints also inherited legacy dated Azure API versions in cases where the v1 endpoint should not receive an `api-version` query string.
+
+## Technical Details
+
+Files modified:
+
+- `application/single_app/model_endpoint_clients.py`
+- `application/single_app/semantic_kernel_loader.py`
+- `application/single_app/route_backend_chats.py`
+- `application/single_app/route_backend_models.py`

+- `application/single_app/static/js/admin/admin_model_endpoints.js`
+- `application/single_app/static/js/workspace/workspace_model_endpoints.js`
+
+Code changes summary:
+
+- Added protocol inference for Azure OpenAI, OpenAI-compatible Foundry `/openai/v1`, and Anthropic messages endpoints.
+- Routed Claude deployments and `/anthropic/` endpoints through an Anthropic messages adapter that preserves the existing `chat.completions.create` call shape.
+- Routed endpoint-bound Semantic Kernel agents through protocol-aware chat services, including an Anthropic service for Claude-backed local agents.
+- Normalized New Foundry Project endpoints to `/openai/v1` for OpenAI-compatible models and to `/anthropic/v1/messages` for Claude deployments.
+- Preserved OpenAI-compatible `/openai/v1` endpoint behavior by omitting the `api-version` query for this normalized inference path. A later 0.250.003 follow-up confirmed that Foundry project `/v1` model endpoints reject `api-version`, including dated preview values.
+- Updated the endpoint modal to use API-version dropdowns with Custom fields, rename Foundry endpoint input copy to Project Endpoint, and derive the project name from `/api/projects/<project>` URLs.
+- Updated endpoint edit validation so blank API key and client secret fields can reuse stored secrets when the existing endpoint indicates the secret is already saved.
+
+## Validation
+

+

+- `pytest ui_tests/test_model_endpoint_request_uses_endpoint_id.py -q` (skipped without UI environment variables)
+
+Before this fix, Claude deployments on New Foundry could fail because the request used an Azure OpenAI `api-version` flow, and endpoint metadata edits could incorrectly demand a previously stored API key. After this fix, Claude deployments are inferred from the deployment name or endpoint path and are called through the Anthropic messages protocol, including for endpoint-bound local agents. Saved endpoint edits can preserve stored secrets without requiring users to paste them again.
+
+Version reference: `application/single_app/config.py` is at **0.241.179** for this original fix.
+
+## Tabular Analysis Follow-Up
+
+Fixed in version: **0.241.186**
+
+### Issue Description
+
+Tabular analysis and large generated tabular exports could still fail after selecting a Claude model endpoint because the tabular helper paths rebuilt Azure-only Semantic Kernel chat services instead of preserving the selected model endpoint context. Some chat-route helper calls also sent Anthropic-incompatible system-only message payloads.
+
+### Root Cause Analysis
+
+The main chat client had protocol-aware endpoint routing, but tabular mini-agents, background generated-output workers, and several summary or history helper calls still assumed Azure OpenAI request behavior. Claude Semantic Kernel services do not support the SK auto function-calling loop used by tabular analysis, so the tabular path also needed a Claude-specific direct planner flow.
+
+### Technical Details
+
+Files modified:
+
+- `application/single_app/functions_model_endpoint_runtime.py`
+- `application/single_app/route_backend_chats.py`
+- `application/single_app/functions_tabular_generated_exports.py`
+- `application/single_app/model_endpoint_clients.py`
+- `application/single_app/functions_settings.py`
+- `application/single_app/route_backend_models.py`
+- `application/single_app/config.py`
+
+Code changes summary:
+
+- Added a shared model endpoint runtime helper that builds provider-aware Semantic Kernel chat services and stores only non-secret endpoint context with background work.
+- Threaded selected endpoint and model metadata into foreground tabular analysis, schema summary generation, generated output creation, and background generated-output processing.
+- Added a Claude/Anthropic tabular branch that uses the existing JSON reviewer planner and direct server-side tool execution instead of SK auto function calling.
+- Allowed literal `anthropic` and `claude` providers in endpoint inference, frontend-visible endpoint filtering, and model connection tests.
+- Converted chat-route summary and history helper calls from system-only payloads to system-plus-user payloads for Anthropic compatibility.
+
+### Validation
+
+Test results:
+
+- `python -m py_compile application/single_app/model_endpoint_clients.py application/single_app/functions_model_endpoint_runtime.py application/single_app/functions_tabular_generated_exports.py application/single_app/route_backend_models.py application/single_app/functions_settings.py application/single_app/route_backend_chats.py functional_tests/test_model_endpoint_protocol_inference.py functional_tests/test_tabular_background_generated_exports.py functional_tests/test_tabular_claude_model_endpoint_support.py`

+- `python functional_tests/test_tabular_background_generated_exports.py`
+- `python functional_tests/test_tabular_claude_model_endpoint_support.py`
+
+Before this follow-up, Claude-backed tabular analysis and background exports could silently fall back to Azure-only service construction or hit Anthropic payload/tool-calling constraints. After this follow-up, selected Claude endpoint metadata is preserved through tabular work and Claude uses an Anthropic-safe planner path.
+
+Version reference: `application/single_app/config.py` is at **0.241.186** for this follow-up.

+# Foundry Workflow API-Key Application Protocol Fix
+
+Fixed in version: **0.241.193**
+
+Superseded in version: **0.241.196**
+
+> Current behavior: Foundry Workflow agents no longer route API-key configurations through the application protocol. Workflow invocation now uses Microsoft Entra ID/RBAC only, while API keys remain limited to model endpoint inference. See `FOUNDRY_AGENT_WORKFLOW_ENTRA_AUTH_BOUNDARY_FIX.md`.
+
+## Issue Description
+
+Foundry Workflow agents configured with an API key could still fail during streaming with a downstream `403` from Foundry:
+
+```text
+Identity(object id: ) does not have permissions for Microsoft.MachineLearningServices/workspaces/agents/action actions.
+```
+
+This happened for discovered Foundry project agents that were saved as workflow-capable entries.
+
+## Root Cause Analysis
+
+SimpleChat normalized discovered project agents into `foundry_workflow` records and invoked them through the generic project Responses endpoint with an `agent_reference`. That path creates a Foundry conversation item and can require Azure RBAC for `Microsoft.MachineLearningServices/workspaces/agents/action`.
+
+For API-key backed discovered agents, the key is valid for the OpenAI-compatible application protocol endpoint, but it does not provide an Entra object id for the identity-gated `agent_reference` conversation item creation path.
+

+
+Files modified:
+

+- `application/single_app/config.py`
+- `docs/explanation/features/v0.241.127/FOUNDRY_WORKFLOW_AGENTS.md`
+
+Code changes summary:
+
+- API-key authenticated Foundry Workflow agents with a discovered `application_name` or `application_id` now route through the application Responses protocol endpoint.
+- Delegated-user workflow calls continue using the generic workflow `agent_reference` conversation path.
+- Workflow metadata still reports `runtime_type: foundry_workflow` and records that the application protocol was used.
+- Existing workflow reference persistence is unchanged for delegated calls.
+
+## Validation
+
+Regression coverage added to `functional_tests/test_foundry_workflow_agent_payload.py` verifies that API-key discovered workflow agents call the New Foundry application streaming path and do not create Foundry conversations.
+
+Expected user impact:
+
+- API-key-backed discovered Foundry agents selected in Workflow mode should no longer fail with the empty identity object id `agents/action` authorization error.
+- Users still need a valid Foundry project API key for the selected project/application.

+# Generated Analysis JSON Preview Wrap Fix
+
+Fixed in version: **0.241.130**
+
+## Issue Description
+
+Generated analysis artifact cards could render JSON preview content as a single unwrapped line segment, which let long preview text extend past the chat card and outside the visible chat window.
+
+## Root Cause
+
+The generated analysis preview fallback and text preview helpers rendered JSON inside `pre` elements without overriding the browser default `white-space: pre`. That preserved line breaks, but it also prevented long lines from wrapping inside the available card width.
+
+## Technical Details
+
+Files modified:
+
+- `application/single_app/static/js/chat/chat-messages.js`
+- `application/single_app/config.py`
+- `ui_tests/test_chat_generated_tabular_output_card.py`
+
+Code changes summary:
+
+- Added a shared generated-analysis preview block formatter in `chat-messages.js`.
+- Applied `white-space: pre-wrap`, `word-break: break-word`, and `overflow-wrap: anywhere` to generated JSON preview blocks so long lines stay inside the card.
+- Added a UI regression test that injects an analysis JSON artifact with a very long preview token and asserts the preview block wraps instead of overflowing.
+- Bumped the application version to `0.241.130`.
+
+Testing approach:
+
+- `node --check application/single_app/static/js/chat/chat-messages.js`
+- `e:/repos/simplechat/.venv/Scripts/python.exe -m py_compile application/single_app/config.py ui_tests/test_chat_generated_tabular_output_card.py`
+- `e:/repos/simplechat/.venv/Scripts/python.exe -m pytest ui_tests/test_chat_generated_tabular_output_card.py -q`
+
+## Validation
+
+Before:
+
+- Long JSON preview lines could overflow the generated artifact card in Chats.
+- Document analysis previews were difficult to read because the preview block preferred horizontal overflow over wrapping.
+
+After:
+
+- Generated JSON preview blocks wrap long lines within the chat card.
+- The UI regression suite now includes a targeted long-line preview scenario for this rendering path.

+# Generated Artifact Pending Approval Actions Fix
+
+Fixed in version: **0.241.128**
+
+## Issue Description
+
+Pending generated artifact promotions in group and public workspaces could be approved, but they had no matching deny or requester cancel path. That left workspace members with pending shells and approval notifications that could not be cleared without manual cleanup.
+
+## Root Cause
+
+The phase 4 promotion workflow only implemented the approval branch after a pending document shell was created. The backend routes, workspace table actions, and folder views did not expose any denial or requester-owned cancellation path for that same shell.

+- `ui_tests/test_workspace_generated_artifact_pending_actions.py`
+- `application/single_app/config.py`
+
+Code changes summary:
+
+- Added group and public backend routes to deny pending generated artifact promotions.
+- Added requester-only cancel routes for pending generated artifact promotions.
+- Cleared matching pending approval notifications when requests are approved, denied, or canceled.
+- Added deny and cancel actions to group and public workspace list and folder views.
+- Added focused functional and UI regression coverage for the new action matrix.
+
+Testing approach:
+
+- Python compile validation for touched backend files.
+- Source-based functional regression for route and UI wiring.
+- Playwright UI regression for pending row action visibility.
+
+## Validation
+
+Before:
+
+- Pending promoted artifacts could only be approved.
+- Requesters could not withdraw a mistaken promotion request.
+- Managers could not explicitly deny a pending promotion.
+- Pending approval notifications remained the only visible signal for stalled requests.
+
+After:
+
+- Managers can approve or deny pending generated artifact promotions.
+- Requesters can cancel their own pending generated artifact promotions.
+- Pending workspace shells and matching notifications are removed when requests are denied or canceled.
+- Approval now also clears the matching pending notifications.

+# Generated Artifact Workspace Promotion Modal Fix
+
+Version: 0.241.096
+
+Fixed/Implemented in version: **0.241.096**
+
+## Issue Description
+
+Generated artifact cards showed a warning toast saying users had to select exactly one workspace scope before using **Add to Workspace**. In a personal conversation, that was confusing because the conversation already had a clear personal workspace destination. In ambiguous scope states, the toast did not help users choose the right destination.
+
+## Root Cause Analysis
+
+The client promotion flow reused the document search scope filter as a hard validation gate. The search scope often defaults to all available workspaces, so a personal conversation could still appear to have multiple possible save targets. When more than one target was present, the flow stopped with a toast instead of offering a guided target selection.
+
+## Technical Details
+
+### Files Modified
+
+- `application/single_app/static/js/chat/chat-messages.js`
+- `application/single_app/config.py`
+- `functional_tests/test_generated_artifact_workspace_promotion_modal.py`
+- `ui_tests/test_chat_generated_tabular_output_card.py`
+
+### Code Changes Summary
+
+- Added conversation-aware target inference so personal, group, and public conversations prefer their own workspace scope.
+- Added a Bootstrap confirmation modal for single inferred targets.
+- Added a Bootstrap chooser modal when multiple save targets are genuinely possible.
+- Removed the dead-end one-scope warning toast from the generated artifact promotion flow.
+- Extended UI coverage for personal confirmation and ambiguous target selection.
+
+## Testing And Validation
+
+- Functional regression: `functional_tests/test_generated_artifact_workspace_promotion_modal.py`
+- UI regression: `ui_tests/test_chat_generated_tabular_output_card.py`
+- JavaScript syntax validation for `application/single_app/static/js/chat/chat-messages.js`
+
+## Impact Analysis
+
+- Personal conversation artifacts now default to a personal workspace confirmation.
+- Ambiguous scope states now let users choose the destination directly from the promotion flow.
+- Group and public conversation artifacts continue to target their conversation workspace and preserve the existing approval behavior.

+# GET MESSAGES AGENT CITATION HYDRATION FIX
+
+Fixed/Implemented in version: **0.241.116**
+
+Related config.py update: `VERSION = "0.241.116"`
+
+## Header Information
+
+- Issue description: Historical chat loads could fall back to compact agent citation payloads, leaving large JSON-style tool results truncated to the preview data stored on the assistant message.
+- Root cause analysis: The active `/api/get_messages` route filtered assistant artifact child records out of the message query before rebuilding the artifact payload map, so it never rehydrated externalized agent citations for the legacy chat loader.
+- Version implemented: 0.241.116
+
+## Technical Details
+
+- Files modified: `application/single_app/route_backend_conversations.py`, `application/single_app/config.py`, `functional_tests/test_get_messages_agent_citation_hydration.py`
+- Code changes summary: Updated `/api/get_messages` to build the assistant artifact payload map before filtering assistant artifact records and then rehydrate visible agent citations from that map before image hydration runs.
+- Testing approach: Added a focused functional regression test that checks the legacy route imports the artifact helpers and applies them in the correct order.
+
+## Validation
+
+- Test results: Focused source-level regression coverage verifies the artifact map is built before filtering and that the visible messages are hydrated afterwards.
+- Before/after comparison: Before the fix, the active chat history loader returned compact citation payloads that could stop at the five-item preview stored on the assistant message. After the fix, the loader restores the full externalized citation payload for frontend rendering.
+- User experience improvements: Large agent citation results remain inspectable after reloading or reopening conversations instead of collapsing back to compact preview JSON.

+# Global Agent Chat Selection Fix - v0.241.122
+
+Fixed in version: **0.241.122**
+
+Related version update: `application/single_app/config.py` was updated to `0.241.122` for this fix.
+
+## Issue Description
+
+When application-level agents were enabled but Workspace Mode was disabled, the Chat page did not render the Agents button. Users could not visibly select the global `researcher` agent, but backend chat paths could still use the stored global selected agent or Semantic Kernel fallback behavior during richer chat flows.
+
+## Root Cause Analysis
+
+- The Chat template rendered the Agents button only when both `enable_semantic_kernel` and `per_user_semantic_kernel` were true.
+- The Chat frontend preload catalog only included global agents when Workspace Mode merged global agents into workspace agents.
+- The backend chat route fell back to stored `selected_agent` or `global_selected_agent` settings when the request did not include an explicit `agent_info` payload.
+- Non-streaming chat also allowed Semantic Kernel orchestrator/kernel fallback steps even when no request agent was selected.
+
+## Technical Details

+### Files Modified

+
+### Code Changes Summary
+
+- The Chat page now renders the Agents button whenever app agents are enabled.
+- Global agents are now included in the Chat agent catalog for global agent mode, and still included in workspace mode when global merge is enabled.
+- Chat response generation now requires an explicit request `agent_info` selection before invoking an agent.
+- The stored global selected agent is no longer written into message metadata unless the frontend sent an explicit selected agent.
+- Non-streaming Semantic Kernel orchestrator/kernel fallback is gated behind an explicit selected agent.
+
+### Testing Approach
+
+- Added `functional_tests/test_global_agent_chat_selection_visibility.py` to verify the template gate, global agent catalog preload, and no-silent-fallback route behavior.
+
+## Impact Analysis
+
+- In global agent mode, users can now visibly enable Agents in Chat and select from global agents.
+- If the user does not enable/select an agent in Chat, normal model chat remains model-only.
+- Rich chat flows such as tabular analysis and search augmentation can still run their own deterministic helpers, but final agent invocation requires a visible explicit agent selection.
+
+## Validation
+
+- Regression coverage verifies global agents are exposed in Chat and stored default agents are not used as hidden runtime fallbacks.

+# Governance Admin Rendering XSS Hardening
+
+Fixed/Implemented in version: **0.242.022**
+
+## Issue
+
+The PR readiness XSS sink check flagged changed admin browser-rendering paths where governance, endpoint, agent, and plugin metadata could reach dynamic HTML sinks or interpolated `data-*` attributes.
+
+## Root Cause
+
+Several changed JavaScript renderers built table rows and action buttons with template strings. Even when values were escaped, the repository guardrail requires new browser-rendering code to prefer DOM node creation, `textContent`, and inert `dataset` assignments for untrusted data.
+
+## Technical Details
+
+Files modified:
+
+- `application/single_app/static/js/admin/admin_agents.js`
+- `application/single_app/static/js/admin/admin_governance.js`
+- `application/single_app/static/js/admin/admin_model_endpoints.js`
+- `application/single_app/static/js/plugin_common.js`
+- `functional_tests/test_governance_enforcement_logic.py`
+- `functional_tests/test_governance_route_and_wiring_coverage.py`
+
+Code changes summary:
+
+- Replaced dynamic admin agent, model endpoint, and plugin table row HTML with DOM nodes and `textContent`.
+- Replaced icon-only `innerHTML` swaps with a Bootstrap icon helper that creates `i` elements directly.
+- Kept static Bootstrap modal shells in place with narrow `xss-check: ignore` comments that document the safe boundary.
+- Updated governance functional tests to align with multi-policy item access and DOM-based endpoint button wiring.
+
+## Validation
+
+Validation run:
+
+- `git diff --check origin/Development`
+- `python -m py_compile` for tracked `application/single_app` Python files
+- `python scripts/check_swagger_routes.py <changed application Python files>`
+- `python scripts/check_xss_sinks.py --base-sha origin/Development --head-sha HEAD <changed browser files>`
+- `python scripts/check_broken_access_control.py --base-sha origin/Development --head-sha HEAD <changed application Python files>`
+- `python -m pytest` for the changed functional test files
+- `python -m pytest` for the changed UI test files
+
+Result: static validation passed, changed functional tests passed, and changed UI tests produced one pass with environment-gated skips for authenticated Playwright scenarios.
+
+## Impact
+
+Admin governance and related endpoint, agent, and action management tables now follow the repository XSS-safe rendering pattern for changed surfaces while preserving the existing user workflows.

+# Governance Personal Actions Enforcement Fix
+
+Fixed/Implemented in version: **0.242.063**
+
+## Issue Description
+
+Governance feature policies treated `Allow All` off with no assigned users or groups as open access. Admins expected that state to deny everyone until explicit users or workspace groups were assigned, especially for personal actions where the Actions workspace tab should disappear and new action creation should be blocked.
+
+Users could still see existing personal actions and create new personal actions after an admin enabled Govern Personal Actions, cleared Allow All, and saved an empty allowlist.
+
+## Root Cause Analysis
+
+`application/single_app/functions_governance.py` returned `True` when a policy had `allow_all: false` and empty `allowed_users` and `allowed_groups`. The workspace template and backend action save route both used the governance helper, so the permissive empty-policy interpretation made the UI and APIs behave as if the user was still allowed.
+
+Personal action read paths also bypassed governance checks in API and Semantic Kernel runtime loading paths, which meant hidden personal actions could still be fetched or loaded if a caller reached those endpoints directly.
+
+## Technical Details
+
+Files modified:
+
+- `application/single_app/functions_governance.py`
+- `application/single_app/functions_personal_actions.py`
+- `application/single_app/route_backend_plugins.py`
+- `application/single_app/semantic_kernel_loader.py`
+- `application/single_app/functions_agent_catalog.py`
+- `application/single_app/static/js/admin/admin_governance.js`
+- `application/single_app/config.py`
+- `functional_tests/test_governance_enforcement_logic.py`
+
+Code changes summary:
+
+- Empty allowlists now deny access when `allow_all` is disabled.
+- Personal action GET, POST, DELETE, agent-catalog labels, and Semantic Kernel runtime loading now respect personal action governance.
+- Raw personal action storage reads remain available for migration and internal helper flows, while governed read helpers are used at user-facing and runtime boundaries.
+- The Governance tab now distinguishes `All users and groups allowed` from `No users or groups allowed`.
+- The app version was updated to `0.242.063` in `application/single_app/config.py`.
+
+## Delegated Action Boundary
+
+Current delegated item policies apply to configured global action instances such as a deployed SQL action or a deployed SimpleChat action. They do not yet apply to broad action types such as every SQL action type regardless of deployment.
+
+That means admins can govern use of a specific deployed global SQL action for selected users or groups, and separately govern a specific deployed global SimpleChat action for another set of users or groups. A future action-type policy layer would be needed to authorize all actions of a type before they are deployed as global action records.
+
+## Validation
+
+Functional coverage in `functional_tests/test_governance_enforcement_logic.py` now validates that:
+
+- disabled governance toggles still bypass policy checks
+- feature and item allowlists still allow assigned users or groups
+- empty allowlists deny access when `allow_all` is disabled
+- personal action API/runtime/catalog entry points use governed access checks
+
+Before the fix, an empty allowlist effectively reopened the governed feature. After the fix, enabling a governance policy and clearing Allow All denies access until explicit users or workspace groups are assigned.

+# Governance Scope Toggle Visibility Fix
+
+Fixed in version: **0.242.062**
+
+## Issue Description
+
+The Admin Settings Governance tab could appear to be missing personal and group governance capabilities. The source template included the full personal, group, and global scope controls, but the runtime governance script hid controls when the matching primary feature switch was disabled.
+
+This made personal actions, personal endpoints, group endpoints, group agents, and group actions look unavailable even though the backend governance policy keys and enforcement hooks still existed.
+
+## Root Cause Analysis
+
+`application/single_app/static/js/admin/admin_governance.js` used `d-none` to remove governance scope toggle wrappers whenever `isGovernanceFeatureApplicable()` returned false. That applicability check is based on primary feature switches such as `allow_user_plugins`, `allow_group_agents`, and `allow_group_custom_endpoints`.
+
+Because the Governance tab removed unavailable controls entirely, admins could not see the complete governance surface or understand that those controls depended on primary feature enablement.
+
+## Technical Details
+
+Files modified:
+
+- `application/single_app/static/js/admin/admin_governance.js`
+- `application/single_app/config.py`
+- `functional_tests/test_governance_admin_scope_toggle_visibility.py`
+- `docs/explanation/fixes/GOVERNANCE_SCOPE_TOGGLE_VISIBILITY_FIX.md`
+
+Code changes summary:
+
+- Scope toggle wrappers are always kept visible in the Governance tab.
+- Scope toggles whose matching primary feature is disabled are marked disabled instead of hidden.
+- Disabled controls receive an explanatory title so the dependency is discoverable.
+- The existing Feature Policies table filtering remains focused on features that are both enabled and governed.
+- The app version was updated to `0.242.062` in `application/single_app/config.py`.
+
+## Validation
+
+Functional coverage was added in `functional_tests/test_governance_admin_scope_toggle_visibility.py` to verify that:
+
+- all nine governance scope controls are present in the admin template
+- runtime JavaScript no longer hides unavailable scope controls with `d-none`
+- unavailable controls are disabled instead of removed from the Governance tab
+
+Before the fix, admins could interpret hidden controls as missing feature support. After the fix, the Governance tab shows the full personal, group, and global governance surface while still preventing inactive feature scopes from being saved as active governance checks.

+# Group Auth Helper Binding Fix
+
+Fixed/Implemented in version: **0.241.100**
+
+## Issue Description
+
+Group workspace actions could fail after startup with `name 'get_current_user_info' is not defined` or `name 'get_current_user_id' is not defined`.
+
+This broke three visible flows:
+
+- Creating a new group workspace.
+- Changing the active group workspace.
+- Uploading files to a group workspace after the active-group switch failed.
+
+Related config update: `application/single_app/config.py` now sets `VERSION = "0.241.100"`.
+
+## Root Cause Analysis
+
+- `application/single_app/functions_group.py` imported auth and settings helpers with star imports.
+- During the full Flask app import path, that star import could capture a partial snapshot of `functions_authentication` before `get_current_user_id` and `get_current_user_info` were defined.
+- The same import-order issue also left `update_user_settings` unavailable from the settings snapshot used by the active-group path.
+- Later group operations looked up those missing names inside `functions_group.py`, which raised `NameError` and caused downstream group upload attempts to fail because no active group was persisted.
+
+## Technical Details
+
+Files modified:
+
+- `application/single_app/functions_group.py`
+- `application/single_app/config.py`
+- `functional_tests/test_group_auth_helper_import_order_fix.py`
+
+Code changes summary:
+
+- Replaced the brittle star-import dependencies in `functions_group.py` with runtime access through the live `functions_authentication` and `functions_settings` module objects.
+- Updated `create_group(...)`, `update_active_group_for_user(...)`, and `require_active_group(...)` to resolve auth and settings helpers at call time.
+- Added a regression test that imports the full app and verifies both helper binding and the create/set-active flows under a request context.
+
+Testing approach:
+
+- Reproduced the failure by importing `app.py` and confirming the auth helper names were missing inside `functions_group.py`.
+- Re-ran the same app-import validation after the fix to confirm the helpers remained available.
+- Added a focused functional test for the import-order regression.
+
+## Validation
+
+Before:
+
+- Group creation could return a 400 with an error message showing `get_current_user_info` was undefined.
+- Active-group changes could fail with a 500 because `get_current_user_id` was undefined.
+- Group file uploads could remain queued or fail after the active-group update never completed.
+
+After:
+
+- Group creation resolves the current session user correctly.
+- Active-group changes resolve the session user correctly and can persist `activeGroupOid`.
+- Group uploads no longer inherit the broken state caused by the failed active-group update.

+# Group Manage Settings Tab Visibility Fix (v0.241.204)
+
+Fixed/Implemented in version: **0.241.204**
+
+Related config.py version update: `application/single_app/config.py` now sets `VERSION = "0.241.204"`.
+
+## Issue Description
+
+The group manage page showed the Settings tab for group owners and admins, but clicking the tab displayed an empty pane. Group retention policy controls and the group file download disable control were present in the template, but remained hidden.
+
+## Root Cause Analysis
+
+The group manage template intentionally rendered the Settings pane with Bootstrap's `d-none` class until the current user's group role was loaded. The JavaScript removed `d-none` from the Settings tab button for owners and admins, but did not remove it from the `#settings` pane itself. This produced a silent blank tab with no JavaScript error.
+
+The group and public workspace download settings PATCH APIs also returned a successful HTTP 200 response without the `success` flag that their frontend save handlers already required.
+
+## Technical Details
+
+### Files Modified
+

+- `application/single_app/route_backend_groups.py`
+- `application/single_app/route_backend_public_workspaces.py`
+- `application/single_app/config.py`
+- `functional_tests/test_group_manage_settings_tab_visibility.py`
+
+### Code Changes Summary
+
+- Unhid the group manage `#settings` pane alongside the Settings tab item for group owners and admins.
+- Kept the group Settings pane hidden for non-admin group roles.
+- Updated the group download settings route to use `assert_group_role(..., allowed_roles=("Owner", "Admin"))` at the write boundary.
+- Added `success: true` to group and public download settings PATCH responses so the existing frontend save handlers show success.
+- Bumped `config.py` from `0.241.203` to `0.241.204`.
+
+## Testing Approach
+
+- Added a functional static regression test that verifies group manage settings visibility wiring, download settings API response contracts, and version/documentation traceability.
+
+## Impact Analysis
+
+Group owners and admins can now see and manage retention policy settings and per-group file download disable settings from the group manage page. Public workspace download settings keep the same UI behavior, with a corrected successful save response.

+# Group And Public Workspace Download Settings Visibility Fix (v0.242.057)
+
+Fixed/Implemented in version: **0.242.057**
+
+Related config.py version update: `application/single_app/config.py` now sets `VERSION = "0.242.057"`.
+
+## Issue Description
+
+The Manage Group and Manage Public Workspace Settings tabs showed the local File Download Settings section even when administrators had not enabled file downloads for that group or public workspace. Owners and admins could see a local disable switch for a feature that was not actually available.
+
+## Root Cause Analysis
+
+The management templates rendered the local `disable_file_downloads` controls unconditionally for workspace owners and admins. The frontend loaded only the workspace-local disable value, while the backend PATCH routes accepted local disable updates without checking whether the admin-level download policy enabled downloads for that target workspace.
+
+## Technical Details
+
+### Files Modified

+
+### Code Changes Summary
+
+- Added admin-policy helpers that determine whether file downloads are enabled for a specific group or public workspace before applying local owner/admin disable settings.
+- Added `file_downloads_admin_enabled` to the manage page API payloads.
+- Hid the local File Download Settings sections by default and only revealed them when the API reports that admin downloads apply to the current workspace.
+- Blocked download settings PATCH calls when administrators have not enabled downloads for the current group or public workspace.
+- Bumped `config.py` to `0.242.057`.
+
+## Validation
+
+### Testing Approach
+
+- Extended the source-level functional regression for group/public management settings to verify backend admin gates, hidden default template sections, frontend visibility toggles, and documentation/version traceability.
+- Extended manage group and manage public workspace UI tests to assert the local download settings section remains hidden when the API reports downloads are not admin-enabled.
+
+### Before/After Comparison
+
+- Before: owners/admins saw a file download disable switch even when file downloads were globally off or not assigned to their workspace.
+- After: owners/admins only see the local file download disable section after administrators enable downloads for that specific group or public workspace.

+# Group Workflow Activity View Gate Fix
+
+Fixed/Implemented in version: **0.241.179**
+
+Related version update:
+- `application/single_app/config.py` reports version `0.241.179` for this fix.
+
+## Issue Description
+
+Group workflow activity links opened the shared `/workflow-activity` page with `scope=group`, but the frontend route was still protected by the personal workflow feature gate. When personal workflows were disabled, the page returned an error before the group workflow activity API could load.
+
+## Root Cause Analysis
+
+The workflow activity page is shared by personal and group workflows, but its Flask route used `@enabled_required('allow_user_workflows')` and `@workflow_user_required`. Those decorators are correct for personal workflow pages and APIs, but they blocked group workflow activity views even when group workflows were enabled and the user had valid group access.

+- Replaced the personal-only decorators on `/workflow-activity` with scope-aware route authorization.
+- Preserved personal workflow checks for personal activity links.
+- Added group workflow checks for group activity links, including group workspaces enabled, group workflows enabled, group assignment gating, and current membership validation.
+- Kept the group activity API path isolated through `/api/group/workflows/activity` and `/api/group/workflows/activity/stream`.
+
+Testing approach:
+- Added `functional_tests/test_group_workflow_activity_view_gate.py` to assert the shared activity page route no longer depends on the personal workflow decorators for group scope.
+- Updated `functional_tests/test_group_workflows_feature.py` version assertions to the current app version.
+
+## Validation
+
+Before:
+- Group workflow activity links could fail with `Allow User Workflows is disabled.` when personal workflows were disabled.
+
+After:
+- Group workflow activity links render the shared activity page under group-specific authorization and then load group activity data from group workflow APIs.
+- Personal workflow activity links still require personal workflows and the WorkflowUser role policy when configured.

+# Group Workflow Assignment Cleanup Fix
+
+Fixed/Implemented in version: **0.241.201**
+
+Related version update:
+- `application/single_app/config.py` reports version `0.241.201` for this fix.
+
+## Issue Description
+
+The Admin Settings form could store malformed values in `group_workflow_allowed_group_ids`. Once the hidden group workflow assignment field contained nested escaped JSON or other junk strings, the admin page rendered and resubmitted that inflated payload, eventually making the form data too large to reliably save unrelated settings.
+
+## Root Cause Analysis
+
+The group workflow assignment normalizer accepted any non-empty string as a group ID. When a previously serialized list was stored as a string inside the list, that escaped blob was treated as one valid assignment. The admin JavaScript then loaded the blob into its assignment set and wrote it back to the hidden field as JSON, preserving the bad value instead of shrinking it.
+
+## Technical Details
+
+Files modified:
+- `application/single_app/functions_settings.py`
+- `application/single_app/static/js/admin/admin_settings.js`
+- `application/single_app/config.py`
+- `functional_tests/test_group_workflow_assignment_cleanup_fix.py`
+- `functional_tests/test_group_workflows_feature.py`
+
+Code changes summary:
+- Group workflow assignment IDs now normalize to canonical UUID values only.
+- Legacy nested JSON-list strings are recursively unwound so valid group UUIDs can be recovered.
+- Malformed escaped payloads, JSON fragments, and arbitrary strings are dropped.
+- `get_settings()` persists cleaned group workflow assignment settings back to Cosmos so future admin page loads stay compact.
+- `update_settings()` applies the same cleanup before saving settings from any caller.
+- Admin Settings JavaScript now performs the same UUID-only cleanup before syncing the hidden form field.
+
+Testing approach:
+- Added `functional_tests/test_group_workflow_assignment_cleanup_fix.py` to validate junk removal, nested UUID recovery, idempotent persisted cleanup, UI wiring, and version alignment.
+- Updated `functional_tests/test_group_workflows_feature.py` to the current app version.
+
+## Validation
+
+Before:
+- A malformed escaped JSON blob could survive as a group workflow assignment ID and keep expanding the hidden Admin Settings payload.
+
+After:
+- The hidden Admin Settings field contains only a compact JSON array of valid group UUIDs.
+- Valid group assignments survive cleanup, including UUIDs nested in legacy serialized list strings.
+- Invalid or malformed values are removed on settings read and before settings save.

+# Group Workspaces Script Declaration Fix
+
+Fixed in version: **0.241.113**
+
+## Issue Description
+
+Opening the Group Workspaces page could fail during browser parsing with `Uncaught SyntaxError: Identifier 'access' has already been declared`. When this happened, the group workspace script stopped before the page finished initializing.
+
+## Root Cause
+
+The group document row renderer declared `const access` twice in the same block. The same access-state change also left duplicate `canChat` and `canRemove` declarations and read `groupStatus` before it was declared. The folder document table had related shared-document access checks that used `access` and `canRemove` without declaring them in the per-document loop.
+
+## Technical Details
+
+Files modified:
+
+- `application/single_app/templates/group_workspaces.html`
+- `application/single_app/config.py`
+- `functional_tests/test_group_workspace_script_declarations.py`
+- `ui_tests/test_group_workspaces_page_script_errors.py`
+
+Code changes summary:
+
+- Consolidated group document row access flags so `access`, `groupStatus`, `canModify`, `canChat`, and `canRemove` are each declared once in the row setup block.
+- Reused those access flags when building row chat, edit, approve, remove, share, and delete actions.
+- Added per-document access flag declarations in the group folder documents table before approval and remove actions are rendered.
+- Updated the application version from `0.241.112` to `0.241.113`.
+
+Testing approach:
+
+- Added a functional regression test that statically verifies the relevant group workspace declaration blocks do not redeclare block-scoped constants.
+- Added a Playwright UI regression test that loads `/group_workspaces` and fails if the page script does not initialize the document rendering functions.
+
+## Validation
+
+Before:
+
+- The browser rejected the Group Workspaces inline script with `Identifier 'access' has already been declared`.
+- Document row rendering could not initialize, leaving the page unusable.
+
+After:

+# Group Workspace File Download Role Fix (v0.241.195)
+
+Fixed/Implemented in version: **0.241.195**
+
+## Issue Description
+
+Group workspace file downloads could be available to regular group users whenever the global and group-level download settings allowed downloads. The intended policy is that enabled group workspace file downloads are limited to group owners, admins, and document managers.
+
+## Root Cause Analysis
+
+The group document download authorization helper validated active group membership with the regular `User` role included. The group workspace page also gated download controls only on the download feature settings and active group assignment, so regular users could see and attempt file downloads when the workspace policy was enabled.
+
+## Technical Details
+
+### Files Modified
+
+- `application/single_app/route_backend_group_documents.py`
+- `application/single_app/templates/group_workspaces.html`
+- `application/single_app/config.py`
+- `functional_tests/test_group_workspace_file_download_permissions.py`
+- `ui_tests/test_group_workspace_file_download_permissions.py`
+
+### Code Changes Summary
+
+- Added a dedicated group document download manager-role policy for owners, admins, and document managers.
+- Applied that policy to single-document and bulk group document download authorization.
+- Returned group document list download flags only for groups where the current user has a download-eligible role.
+- Updated group workspace UI helpers so regular users do not see download menu items or bulk download controls.
+- Bumped `config.py` version to `0.241.195`.
+
+### Testing Approach
+
+- Added source-level regression coverage for the backend role guard and frontend download control gating.
+- Added a Playwright UI regression that mocks downloads as enabled for a regular group user and verifies download controls remain hidden and guarded.
+
+## Impact Analysis
+
+Regular group users can still view and chat with group documents according to existing group access rules, but they cannot download source files even when downloads are enabled for the group workspace. Owners, admins, and document managers keep the enabled download workflow.

+# Group Workspace Identities Permission UI Fix
+
+Fixed/Implemented in version: **0.241.114**
+
+Related version update: `application/single_app/config.py` was incremented to `0.241.114` for this fix.
+
+## Issue Description
+
+Regular group users could see the Group Workspaces Identities tab even though the group identity APIs are limited to group managers. Because those users cannot list or manage workspace identities, the tab could render as an empty or unclear surface.
+
+## Root Cause Analysis
+
+The backend already enforced group identity permissions with the manager roles `Owner`, `Admin`, and `DocumentManager`, but the group workspace navigation did not reflect that role boundary. The shared identity UI also assumed callers were allowed to load identities, so it did not have a dedicated no-permission render state for group users.
+
+## Technical Details
+
+Files modified:
+
+- `application/single_app/config.py`
+- `application/single_app/static/js/workspace/workspace-identities.js`
+- `application/single_app/templates/group_workspaces.html`
+- `application/single_app/templates/_sidebar_nav.html`
+- `functional_tests/test_group_workspace_identities_permissions.py`
+- `ui_tests/test_group_workspace_identities_permissions.py`
+
+Code changes summary:
+
+- Added permission-aware rendering to the shared workspace identities component with a clear alert when identity management is not allowed.
+- Added refresh hooks so the group page can update the identity component after active group or role changes.
+- Hid the group Identities tab, section selector option, and sidebar entry by default, then revealed them only for `Owner`, `Admin`, and `DocumentManager` roles.
+- Kept the backend manager-only access model intact and documented `DocumentManager` as an allowed role.
+- Added functional and UI regression coverage for manager-only group identity navigation.
+
+## Validation
+
+Test coverage:
+
+- `functional_tests/test_group_workspace_identities_permissions.py`
+- `ui_tests/test_group_workspace_identities_permissions.py`
+
+Before:
+
+- Regular group users could see an Identities navigation target despite not having API permission.
+- The shared identity component had no explicit no-permission UI state.
+
+After:
+
+- Regular group users do not see the Identities navigation in the group tab list, mobile section selector, or sidebar.
+- If the identity panel is reached indirectly, it shows `You do not have permission to manage or view identities for this group.`
+- Group managers continue to use the existing identity list and management controls.

+# Home Page Logo Upload Quality Fix
+
+Fixed/Implemented in version: **0.241.059**
+
+## Overview
+
+The home page logo size control introduced in v0.241.058 exposed a quality problem in the upload pipeline. Uploaded custom logos were still being reduced to `100px` tall before storage, so increasing the main-page logo size could enlarge an already downsampled raster and make the result appear soft or blurry.
+
+## Root Cause
+
+- The admin logo upload path resized both light and dark custom logos to `100px` tall before converting them to PNG and storing them in settings.
+- The homepage logo size control can render the logo significantly larger than `100px`, which meant the browser was forced to upscale a small stored asset.
+- The upload pipeline also logged the full base64 logo payload, which becomes increasingly noisy and expensive as stored logo quality improves.
+
+## Files Modified
+
+- `application/single_app/route_frontend_admin_settings.py`
+- `application/single_app/templates/admin_settings.html`
+- `functional_tests/test_logo_upload_storage_resolution.py`
+- `ui_tests/test_admin_home_page_logo_scale_slider.py`
+- `application/single_app/config.py`
+
+## Code Changes
+
+1. Added a dedicated `prepare_logo_image_for_storage(...)` helper for custom logo uploads.
+2. Replaced the legacy `100px` storage resize with a bounded `500px` maximum stored height.
+3. Continued converting uploaded logos to PNG for consistent downstream serving, but now save them with `optimize=True`.
+4. Updated both light and dark logo upload paths to use the shared helper.
+5. Replaced full base64 upload log entries with summary metadata including original size, stored size, and PNG byte length.
+6. Updated the admin branding help text to explain that uploaded logos are stored at up to `500px` tall to support sharper main-page rendering.
+
+## Validation
+
+- Added `functional_tests/test_logo_upload_storage_resolution.py` to guard against reintroducing the legacy `100px` upload resize.
+- Updated the admin home page logo scale UI test header version to track the current app version.
+- Verified editor diagnostics were clean for the touched Python, HTML, and test files.
+
+## User Impact
+
+- Uploaded custom logos now retain enough resolution for the main page logo size control to render sharply.
+- The app still bounds stored logo size so the settings document does not grow without limit.
+- Branding admins receive clearer guidance in the upload UI about how custom logo storage behaves.

+# Image Message Hydration Fix
+
+Fixed/Implemented in version: **0.241.024**
+
+## Overview
+
+Generated images were being stored successfully, but the chat renderer could still fail to display them after streaming or after a refresh. Collaborative conversations also attempted to mirror the raw generated-image payload into the collaboration message store, which could exceed the Cosmos DB item-size limit and interrupt the shared AI stream before the final image message was emitted.
+
+## Root Cause
+
+- The shared non-AI renderer only kept message bodies that still had visible plain text after HTML stripping. Image bubbles render as an `<img>` tag, so the renderer dropped the entire message body even when a valid image source existed.
+- Single-user and uploaded-image storage duplicated chunking logic across multiple routes, which made reassembly and response handling harder to keep consistent.
+- Collaboration mirroring reused legacy image metadata and then copied generated image content directly into the collaboration message document, which broke the intended lightweight-reference design and could trigger `RequestEntityTooLarge` in Cosmos DB.
+- The collaboration stream bridge still emitted the mirrored collaboration message content directly for image completions instead of using a collaboration-specific image endpoint, so the live shared response path stayed inconsistent with the message reload path.
+- The collaboration stream completion transformer reassigned `updated_conversation_doc` inside its nested closure, which made Python treat that name as a local variable and raised `cannot access local variable 'updated_conversation_doc'` before the mirrored image response could be saved.
+
+## Files Modified
+
+- `application/single_app/functions_image_messages.py`
+- `application/single_app/collaboration_models.py`
+- `application/single_app/functions_collaboration.py`
+- `application/single_app/route_backend_chats.py`

+- `functional_tests/test_collaboration_image_reference.py`
+- `ui_tests/test_chat_generated_image_rendering.py`
+- `application/single_app/config.py`
+
+## Code Changes
+
+1. Added a shared helper for image document chunking, conversation-response hydration, binary decoding, and image-content reassembly.
+2. Replaced the duplicated chunking logic in generated-image storage and uploaded-image storage with the shared helper.
+3. Replaced the duplicated image reassembly logic in both conversation message endpoints with the shared helper so refresh behavior stays consistent.
+4. Added a collaboration image URL builder and a collaboration image endpoint that serves the actual source image content on demand.
+5. Stopped collaboration image mirroring from copying raw base64 content or inline data URLs into the collaboration message record.
+6. Updated the collaboration serializer and live stream bridge so shared image responses always use the collaboration image endpoint instead of the mirrored placeholder content.
+7. Updated the shared chat renderer so image messages always keep their visible image markup even when the message body contains no plain text.
+8. Fixed the collaboration stream completion closure so synced conversation state uses dedicated local names instead of shadowing `updated_conversation_doc` inside the nested transformer.
+
+## Validation
+
+- Added helper-backed functional regressions for base64 decoding, chunked storage, large-image reassembly, and collaboration image references.
+- Added a UI regression that appends image messages through the shared chat renderer and verifies both single-user and collaboration image bubbles remain visible.
+- Verified editor diagnostics were clean for the touched Python and JavaScript files.
+
+## User Impact
+
+- Generated images now display again in single-user chat instead of rendering only the surrounding metadata and actions.
+- Refreshing a conversation now consistently rehydrates chunked images through the shared image helper.
+- Collaborative image responses no longer try to persist oversized base64 payloads inside the collaboration container.
+- Shared image-generation streams now complete with a collaboration image URL instead of failing during the mirror step.
+- Participants in collaborative conversations now load mirrored images through a collaboration-specific image endpoint backed by the original source message.
+- Shared image-generation streams no longer fail on the `updated_conversation_doc` closure scoping bug during collaboration completion.

+# Image Proposal Inline Placement Guidance Fix
+
+Fixed/Implemented in version: **0.241.138**
+
+## Issue Description
+
+Image proposal cards could appear at the end of a generated response instead of staying near the slide, paragraph, or visual suggestion they supported. The guidance also encouraged a single proposal, even when several distinct visuals would be valuable.
+
+## Root Cause Analysis
+
+The chat renderer preserves `simpleimage` blocks wherever the model emits them, but the system guidance was too soft about placement and still told the model to prefer one proposal with a low upper bound. That made end-of-response image cards more likely for slide-deck style answers.
+
+## Technical Details
+
+### Files Modified
+
+- `application/single_app/functions_image_generation.py`
+- `application/single_app/config.py`
+- `functional_tests/test_image_proposal_pipeline.py`
+
+### Code Changes Summary
+
+- Strengthened image proposal guidance so each `simpleimage` block should be emitted inline immediately after the paragraph, bullet, slide section, or visual suggestion it supports.
+- Added slide-deck-specific placement guidance to keep proposal cards inside the relevant slide section.
+- Replaced the previous preference for one proposal with value-based guidance that allows zero, one, or multiple distinct image proposals.
+- Bumped `config.py` version to `0.241.138`.
+
+### Testing Approach
+
+- Updated the image proposal pipeline functional test to verify the guidance includes inline placement and flexible count instructions.
+- Verified the old “prefer one/up to four” wording is absent.
+
+## Impact Analysis
+
+The proposal approval workflow is unchanged. Future model responses should keep image generation cards inline with the content they support and can include as many useful proposals as the response warrants, including just one when that is enough.
+
+## Validation

+# Image Proposal Streaming Card UI Fix
+
+Fixed/Implemented in version: **0.241.137**
+
+## Issue Description
+
+Inline image proposal cards looked rough while streaming. The status appeared as a warning alert and could be broken up by leaked placeholder markup. Completed proposal cards also showed the full generation prompt by default, creating a noisy chat experience and making long generated text hard to scan.
+
+## Root Cause Analysis
+
+The image proposal placeholder HTML included its own replacement token as a data attribute. After replacing the markdown token with the placeholder, the injector performed a second generic token replacement and could replace the token inside the newly inserted HTML. This corrupted the opening tag and exposed `data-image-proposal` attributes in the chat message.
+
+## Technical Details
+
+### Files Modified
+
+- `application/single_app/static/js/chat/chat-inline-image-proposals.js`
+- `application/single_app/static/css/chats.css`
+- `application/single_app/config.py`
+- `ui_tests/test_chat_inline_image_proposal_cards.py`
+
+### Code Changes Summary
+
+- Replaced the streaming warning alert with a chart-style card placeholder.
+- Removed token-bearing attributes from inserted image proposal placeholders and made token injection avoid replacing inside newly inserted HTML.
+- Hid the image generation prompt by default; it is only shown in the edit panel.
+- Added wrapping and overflow handling for long titles, descriptions, badges, statuses, and prompt editor text.
+- Bumped `config.py` version to `0.241.137`.
+
+### Testing Approach
+
+- Updated the Playwright UI regression test for image proposal cards.
+- Added assertions for clean streaming placeholders, hidden prompts, edit visibility, and absence of leaked `data-image-proposal` text.
+
+## Impact Analysis
+
+The image proposal workflow remains opt-in and uses the same approval, edit, cancel, and approve-all actions. The visible experience is cleaner during streaming and less cluttered after the proposal is complete.
+
+## Validation

+- `python -m py_compile ui_tests/test_chat_inline_image_proposal_cards.py`

+# Inline Chart Color Export Override Fix
+
+Fixed/Implemented in version: **0.241.146**
+
+## Issue Description
+
+Inline chart color edits made in the chat UI updated the rendered chart, but per-message Word, PowerPoint, and email draft exports still used the saved assistant message from the backend. Exported chart PNGs could therefore ignore palette selections or swatch changes made in the current browser session.
+
+## Root Cause Analysis
+
+The chart color editor updated the chart card and hidden markdown in the browser. Backend export routes authorized and loaded the saved message by `message_id` and `conversation_id`, then rendered that stored content. The export request did not include the edited markdown, so the backend had no access to the current chart color spec.
+
+## Technical Details
+
+Files modified:
+

+Code changes summary:
+
+- Per-message Word, PowerPoint, and email draft export requests now include `message_content_override` for assistant messages.
+- Backend export routes still authorize the saved message by id, then apply the override only for rendering the export response.
+- Generated Markdown artifact PowerPoint exports ignore the visible-message override and continue exporting the selected artifact source.
+- The chart UI regression now checks that edited chart colors are sent in the export request payload.
+
+## Validation
+
+Validation approach:
+
+- Functional tests verify frontend/backend export override wiring.
+- UI regression coverage verifies edited chart markdown reaches the PowerPoint export request payload.
+- Syntax checks cover changed JavaScript and Python files.
+
+Expected behavior:
+
+- A chart recolored in chat exports with the selected colors in Word, PowerPoint, and email draft chart PNG paths.
+- Export authorization remains tied to the stored conversation and message ids.
+- Reloading the conversation still restores saved content unless the chart edit is persisted in a later feature.

+# Inline Chart Color Preservation Fix
+
+Fixed/Implemented in version: **0.241.139**
+
+## Issue Description
+
+Users could ask for chart colors, such as fruit-colored pie slices, but rendered pie charts still used the default palette. Re-asking the model for different colors did not visibly change the chart.
+
+## Root Cause Analysis
+
+The model and chart tool could provide color values, but the browser chart normalizer replaced pie, doughnut, and polar-area slice colors with the default palette. The export PNG normalizer used the same fallback behavior. Common named colors were also rejected unless they were already CSS hex, RGB, or HSL strings.

+
+### Code Changes Summary
+
+- Preserved explicit `backgroundColor` and `borderColor` arrays for pie, doughnut, and polar-area charts in the browser renderer.
+- Preserved the same slice colors in server-side PNG export rendering.
+- Added safe named color normalization for common color words and semantic fruit labels such as `red`, `orange`, `green`, `apple`, `oranges`, and `pears`.
+- Updated chart guidance and chart tool metadata so models know to use per-slice color arrays when users request specific colors.
+- Bumped `config.py` version to `0.241.139`.
+
+### Testing Approach
+
+- Added chart plugin coverage for semantic pie slice colors.
+- Added export helper coverage for requested pie slice colors.
+
+## Impact Analysis

+# Inline Chart Streaming Flash Fix
+
+Fixed/Implemented in version: **0.241.141**
+
+## Issue Description
+
+Inline charts could render before the assistant response finished, then visibly flash while additional streamed text continued to arrive after the chart block.
+
+## Root Cause Analysis
+
+The streaming renderer replaced the full assistant message HTML on every content chunk. When a complete `simplechart` block was already present, that replacement destroyed the hydrated Chart.js canvas and immediately recreated it, causing repeated visual flashes until the response completed.

+- Preserved chart nodes keep the same canvas and Chart.js instance while surrounding text continues to stream.
+- Unused preserved chart nodes are destroyed through the shared chart cleanup helper to avoid leaking Chart.js instances.

+# Inline Image Proposal Bulk Action Alignment Fix
+
+Fixed/Implemented in version: **0.241.142**
+
+## Issue Description
+
+The `Approve all image proposals` button appeared visually detached from the assistant message content, sitting toward the middle of the chat bubble instead of aligning with the inline image proposal card flow.
+
+## Root Cause Analysis
+
+The bulk action container was constrained to the image proposal card width and also used Bootstrap right alignment. On wide assistant messages, that placed the button near the middle of the available message area.

+# Inline Image Proposal Result Placement Fix
+
+Fixed/Implemented in version: **0.241.140**
+
+## Issue Description
+
+Approved inline image proposal cards generated images successfully, but the generated image was appended as a separate conversation image message instead of appearing where the proposal card was approved.
+
+## Root Cause Analysis
+
+The approval client called the normal image-message append path after generation. The saved image message already carried proposal metadata, but the chat loader did not use that metadata to associate generated images back to the assistant message that requested them.
+
+## Technical Details
+
+Files modified:
+
+- `application/single_app/static/js/chat/chat-inline-image-proposals.js`
+- `application/single_app/static/js/chat/chat-messages.js`
+- `application/single_app/static/css/chats.css`
+- `application/single_app/route_backend_chats.py`
+- `ui_tests/test_chat_inline_image_proposal_cards.py`
+- `application/single_app/config.py`
+
+Code changes summary:
+
+- Generated image proposal approvals now render the returned image inside the original proposal card.
+- Multiple approved proposals are queued client-side and cards show queued/generating/completed status in order.
+- Saved generated image messages with `metadata.image_proposal.source_assistant_message_id` are folded back into their source assistant proposal card during conversation reload.
+- The approval endpoint returns only the proposal association metadata needed by the frontend.
+
+## Validation
+
+Validation commands:
+
+- `node --check application/single_app/static/js/chat/chat-inline-image-proposals.js application/single_app/static/js/chat/chat-messages.js`
+- `python -m py_compile application/single_app/route_backend_chats.py ui_tests/test_chat_inline_image_proposal_cards.py`
+- `python -m pytest ui_tests/test_chat_inline_image_proposal_cards.py -q`
+
+Expected behavior:
+
+- Approving one proposal replaces the proposal card contents with the generated image.
+- Approving several proposals queues them and updates each card as it starts and completes.
+- Reloading the conversation keeps generated proposal images inline with their original cards instead of showing duplicate standalone image bubbles.

+# Inline Visual Export PNG Fix
+
+Fixed/Implemented in version: **0.241.143**
+
+## Issue Description
+
+Per-message exports did not consistently carry inline visuals into the exported artifact. PowerPoint exports could omit charts entirely for structured slide-deck responses, Word exports did not convert approved inline image proposal blocks into embedded image media, and email drafts only prepared chart PNG downloads while leaving image proposal JSON-like text in the body.
+
+## Root Cause Analysis
+
+Charts already had a backend PNG renderer, but structured PowerPoint exports disabled appendix slides and did not extract rendered chart images from each authored slide section. Approved `simpleimage` proposal results were associated to their source assistant message in the browser, but the export backend did not perform the same association or replace `simpleimage` blocks with exportable image HTML. The PowerPoint parser also treated authoring labels such as `Title:` and `Bullet Points:` as literal slide bullets.
+
+## Technical Details
+
+Files modified:
+
+- `application/single_app/route_backend_conversation_export.py`
+- `application/single_app/static/js/chat/chat-message-export.js`
+- `application/single_app/config.py`
+- `functional_tests/test_per_message_powerpoint_export.py`
+- `functional_tests/test_per_message_export.py`
+- `functional_tests/test_conversation_export_inline_chart_images.py`
+
+Code changes summary:
+
+- Added export-side generated image proposal lookup and PNG data URI rendering for approved `simpleimage` blocks.
+- Reused one rendered-content path for Word, PowerPoint, and email exports so charts and generated images are handled consistently.
+- Added structured PowerPoint slide image extraction and inline placement so charts/images stay with the slide section where they appear.
+- Cleaned structured slide labels so `Title:`, `Bullet Points:`, and visual block metadata do not appear as exported slide bullets.
+- Broadened email PNG attachment payloads from chart-only to chart-or-image visuals.
+
+## Validation
+
+Test coverage added or updated:
+
+- `functional_tests/test_per_message_powerpoint_export.py`
+- `functional_tests/test_per_message_export.py`
+- `functional_tests/test_conversation_export_inline_chart_images.py`
+
+Expected behavior:
+
+- PowerPoint exports embed chart and generated-image PNG media on the appropriate structured slide.
+- Word exports embed approved generated image proposal PNGs as document media.
+- Email draft export downloads PNG payloads for both charts and generated images and references them cleanly in the draft body.
+- Exported PowerPoint slides no longer show label scaffolding such as `Title:` or `Bullet Points:` as slide bullets.
+
+Config version reference:
+
+- `application/single_app/config.py` updated to `0.241.143`.

+# Large Tabular Generated Export Timeout Fix
+
+Fixed in version: **0.241.046**
+
+## Issue Description
+
+Large tabular generated JSON or CSV exports could appear hung and eventually fail when the work exceeded the Flask/Gunicorn request lifetime. A production log sample showed a 3,539-row workbook export split into 1,592 model batches, with the request terminated by a worker timeout while batch 298 was being processed.
+
+## Root Cause Analysis
+
+The generated structured export path ran synchronously inside the chat request. When the batch count was high, the request could spend hours calling the model and only keep progress in process memory. If Gunicorn terminated the worker, the stream ended, progress was lost, and the UI kept showing the last emitted batch state.
+
+## Version Implemented
+
+Fixed in version: **0.241.046**
+
+## Technical Details
+
+### Files Modified
+
+- `application/single_app/functions_tabular_generated_exports.py`
+- `application/single_app/route_backend_chats.py`
+- `application/single_app/background_tasks.py`
+- `application/single_app/functions_simplechat_operations.py`
+- `application/single_app/config.py`
+- `application/single_app/static/js/chat/chat-messages.js`
+
+### Code Changes Summary
+
+- Added a durable export run container partitioned by user.
+- Added background queue, status, processing, retry, and checkpoint helpers.
+- Added a scheduler loop that claims and processes due export runs.
+- Added an explicit user-scoped generated artifact upload helper for background workers.
+- Added a chat status API for current-user export progress.
+- Added frontend progress rendering and polling for queued background exports.
+
+### Testing Approach
+
+- Added static functional regression coverage for queue/status/UI wiring.
+- Added Playwright UI regression coverage for queued progress and completed download state.
+- Compiled all modified Python modules.
+
+## Impact Analysis
+
+Large structured exports no longer rely on a single web request staying alive for the entire model-processing workload. Users get clearer progress, and completed batches are preserved so worker restarts can resume instead of restarting from the beginning.
+
+## Validation
+
+### Before
+
+- The chat request could time out mid-export.
+- Progress could stall on the last streamed batch message.
+- Completed model batches were not durable until the final file was produced.
+
+### After
+
+- Oversized exports queue a durable background run.
+- Progress is visible through the chat card and status API.
+- Input and per-batch output checkpoints survive worker restarts.
+- The final generated artifact is attached to the chat when complete.
+
+## Related Version Updates
+
+- `application/single_app/config.py` was updated to version **0.241.046**.

+# Local Chat OpenLayers Assets Fix
+
+Fixed/Implemented in version: **0.241.116**
+
+## Issue Description
+
+Customers in privacy-restricted browsers could see chat stay on the plain `Streaming...` placeholder while the browser console reported tracking-prevention warnings for `https://cdn.jsdelivr.net/npm/ol@10.6.1/...`. The chat page was loading OpenLayers CSS and JavaScript from jsDelivr even though SimpleChat expects runtime assets to be served locally.
+
+## Root Cause Analysis
+
+- The chat template referenced OpenLayers from jsDelivr for inline Azure Maps visualizations.
+- The Content Security Policy still allowed jsDelivr for script and style sources.
+- The admin landing-page SimpleMDE editor disabled FontAwesome auto-download but left spell checking at the default, which can request CDN-hosted dictionary files.
+
+## Version Implemented
+
+- **0.241.116**
+- Application version updated in `application/single_app/config.py` to `0.241.116`.
+
+## Files Modified

+- `functional_tests/test_chat_local_openlayers_assets.py`
+
+## Code Changes Summary
+
+- Vendored OpenLayers 10.6.1 JavaScript, source map, and CSS under SimpleChat static assets.
+- Updated the chat template to load OpenLayers from `url_for('static', ...)` instead of jsDelivr.
+- Removed jsDelivr from `script-src` and `style-src` in the application Content Security Policy.
+- Disabled SimpleMDE spell checking for the admin landing-page editor so it does not request CDN dictionary files.
+- Hardened local SimpleMDE defaults so FontAwesome auto-download stays disabled and spell checking only initializes when explicitly enabled.
+- Removed obsolete CDN examples from shared template comments to avoid misleading scans.
+- Added regression coverage for local OpenLayers asset references and CSP behavior.
+
+## Testing Approach
+
+- Added `functional_tests/test_chat_local_openlayers_assets.py` to statically validate the local asset contract.
+- Updated `ui_tests/test_chat_inline_azure_maps_rendering.py` so the browser test stubs local OpenLayers static paths and fails if jsDelivr is requested.
+
+## Impact Analysis
+
+- Chat no longer depends on jsDelivr for OpenLayers visualizations.
+- Privacy/tracking-prevention settings that block third-party CDN storage should no longer interfere with loading the OpenLayers library used by inline map cards.
+- The app CSP now aligns with the local-runtime asset expectation for scripts and styles.
+
+## Validation
+
+- Before: chat loaded OpenLayers from jsDelivr and CSP allowed that external script/style source.
+- After: chat loads OpenLayers from SimpleChat static files and CSP script/style sources are local-only.

+# Microsoft Graph Calendar Invites And Capabilities Fix
+
+Fixed/Implemented in version: **0.241.037**
+
+## Overview
+
+The built-in Microsoft Graph action could read calendar data, mail, and directory information, but it could not create calendar invites, create Microsoft Teams meetings, or expose action-level and agent-level capability toggles like the built-in SimpleChat action.
+
+## Root Cause
+
+- `msgraph_plugin.py` only exposed read-oriented operations plus mail read-state updates, so there was no Graph action for calendar invite creation.
+- Microsoft Graph actions did not have a shared capability definition, normalization, or runtime overlay path, so per-action defaults and per-agent overrides were unavailable.
+- The workspace action modal and agent modal only rendered capability controls for SimpleChat, leaving Microsoft Graph on the generic endpoint/auth flow.
+
+## Files Modified
+
+- `application/single_app/functions_msgraph_operations.py`
+- `application/single_app/semantic_kernel_plugins/msgraph_plugin.py`
+- `application/single_app/semantic_kernel_loader.py`
+- `application/single_app/route_backend_plugins.py`
+- `application/single_app/static/js/plugin_modal_stepper.js`

+- `functional_tests/test_msgraph_agent_action.py`
+- `ui_tests/test_workspace_msgraph_action_modal.py`
+- `ui_tests/test_agent_modal_msgraph_capabilities.py`
+
+## Code Changes Summary
+
+1. Added shared Microsoft Graph capability definitions plus helpers for action defaults and per-agent runtime overlays.
+2. Added `create_calendar_invite` to the Microsoft Graph plugin, including support for Teams meetings via `isOnlineMeeting` and `onlineMeetingProvider`.
+3. Expanded invite attendee resolution so an action can include members from the current or specified SimpleChat group while deduplicating attendees and skipping the organizer.
+4. Applied Graph capability overlays in `semantic_kernel_loader.py` so agent `other_settings.action_capabilities` can narrow the enabled Graph functions at runtime.
+5. Updated the workspace action modal to treat Microsoft Graph as a built-in action with default capability toggles instead of exposing a user-editable endpoint.
+6. Updated the agent modal to render per-agent Microsoft Graph capability toggles alongside the existing SimpleChat controls.
+
+## Validation
+
+- Functional test: `functional_tests/test_msgraph_plugin_operations.py`
+- Functional test: `functional_tests/test_msgraph_agent_action.py`
+- UI test: `ui_tests/test_workspace_msgraph_action_modal.py`
+- UI test: `ui_tests/test_agent_modal_msgraph_capabilities.py`
+
+## Impact
+
+- Agents can now create Microsoft Graph calendar invites, optionally add current group members as attendees, and create Microsoft Teams meetings in one action.
+- Workspace creators can set default Microsoft Graph capabilities per action, and agents can narrow those defaults per assignment.
+- Microsoft Graph actions now behave like other built-in actions in the workspace and agent modals instead of falling back to the generic external-plugin flow.

+# Microsoft Graph Pending Actions Container Import Fix
+
+Fixed/Implemented in version: **0.241.177**
+
+## Issue Description
+
+Starting the Flask app could fail while importing `functions_msgraph_pending_actions.py` because the module imported `cosmos_msgraph_pending_actions_container`, but `config.py` did not define that Cosmos container export.
+
+## Root Cause Analysis
+
+The Microsoft Graph pending-action helper expected a dedicated `msgraph_pending_actions` Cosmos container for user-owned mail and calendar actions. The container name and object were missing from the centralized Cosmos initialization block in `config.py`.
+
+## Technical Details
+
+- Files modified: `application/single_app/config.py`
+- Added `cosmos_msgraph_pending_actions_container_name = "msgraph_pending_actions"`.
+- Added `cosmos_msgraph_pending_actions_container` using `PartitionKey(path="/user_id")` so pending actions remain user-scoped.
+- Updated `VERSION` in `config.py` to `0.241.177`.
+
+## Validation
+
+- Added `functional_tests/test_msgraph_pending_actions_config_container.py` to verify the container name, exported container symbol, and `/user_id` partition key without requiring a live Cosmos connection.
+- Ran Python syntax checks for `config.py`, `functions_msgraph_pending_actions.py`, and the new functional test.

+# MSG Processor Metadata Argument Fix
+
+Fixed/Implemented in version: **0.250.031**
+
+## Issue Description
+
+Uploading an Outlook `.msg` file could fail during background processing with:
+
+```text
+process_msg() got an unexpected keyword argument 'auto_extract_metadata'
+```
+
+## Root Cause Analysis
+
+The document upload dispatcher passes a shared processor argument set to file processors that participate in the final metadata extraction flow. The new Outlook MSG processor did not include the `auto_extract_metadata` keyword argument in its function signature, so dispatching `.msg` uploads raised a `TypeError` before text extraction could run.
+
+## Technical Details
+
+Files modified:
+
+- `application/single_app/functions_documents.py`
+- `application/single_app/config.py`
+- `functional_tests/test_msg_processor_auto_metadata_argument.py`
+
+Code changes summary:
+
+- Added `auto_extract_metadata=True` to `process_msg`.
+- Reused the MSG processor settings object for chunk configuration and metadata extraction checks.
+- Added a final metadata extraction call for direct `process_msg` usage when metadata extraction is enabled.
+- Added a regression test that validates the MSG processor accepts the shared dispatcher argument.
+- Updated `config.py` from `0.250.030` to `0.250.031`.
+
+## Validation
+
+Testing approach:
+
+- Compile the modified backend and regression test files.
+- Run the focused functional regression test.
+- Run repository whitespace validation.
+
+Before the fix, `.msg` uploads failed before processing because the processor signature rejected the dispatcher argument. After the fix, the MSG processor accepts the shared metadata argument and can continue through Outlook MSG text extraction and chunk indexing.

+# New Foundry Provider API Version Guidance Fix
+
+Fixed in version: **0.250.006**
+
+## Issue Description
+
+Admins configuring New Foundry project endpoints for non-OpenAI model providers could reasonably try a dated preview **OpenAI API Version** because the setup guide and in-product model endpoint modal did not clearly distinguish Foundry project discovery versions from the normalized `/openai/v1` inference path. Field testing with Grok, Meta/Llama, and DeepSeek showed that the `/v1` path rejects `api-version` query values.
+
+## Root Cause Analysis
+
+Simple Chat correctly stores Foundry **Project API Version** separately from **OpenAI API Version**, but the guidance did not clearly explain the difference. The OpenAI-compatible Foundry runtime normalizes project endpoints to `/openai/v1`, where the service expects endpoint-default version behavior and rejects an `api-version` query parameter.
+
+## Technical Details
+
+Files modified:
+
+- `application/single_app/static/js/admin/admin_model_endpoints.js`
+- `application/single_app/static/js/workspace/workspace_model_endpoints.js`
+- `application/single_app/model_endpoint_clients.py`

+- `functional_tests/test_new_foundry_endpoint_api_version_handling.py`
+- `ui_tests/test_model_endpoint_request_uses_endpoint_id.py`
+
+Code changes summary:
+
+- Kept the New Foundry OpenAI API version default at endpoint default `v1` in both global and workspace endpoint editors after field testing showed Foundry project `/openai/v1` rejects `api-version` query parameters.
+- Updated OpenAI-compatible Foundry runtime calls so configured dated preview values are not sent as `api-version` query values on the normalized `/openai/v1` inference path.
+- Added a non-streaming retry when a provider completes a streaming chat response without emitting assistant text, preventing a blank assistant message when the fallback call can recover content.
+- Limited `reasoning_effort` to known OpenAI reasoning model families after live probes showed Foundry-hosted non-OpenAI model families can fail or return empty content when this model-specific parameter is sent.
+- Folded saved memory values into the latest user message as plain background notes for Foundry-hosted non-OpenAI chat-completions models after live app tests showed memory system messages can trigger provider-side content-filter blocks.
+- Consolidated sync model endpoint client construction behind `build_model_endpoint_sync_chat_client()` so chat, workflows, and metadata extraction share the same provider/auth/protocol behavior. Existing Semantic Kernel consumers continue through `build_semantic_kernel_chat_service_for_model()`.
+- Updated stream lifecycle counters so app thought events no longer count as assistant content events.
+- Added modal guidance explaining that Foundry **Project API Version** controls discovery and usually stays `v1`, while **OpenAI API Version** controls model inference.
+- Added setup guide guidance for Grok, Meta/Llama, DeepSeek, and other provider families that hit `/v1` API-version query errors.
+- Clarified that API-key endpoints are inference-only and require manual deployment rows when discovery is unavailable.
+- Updated tests that previously locked in the old `v1` New Foundry default.
+
+## Validation
+
+Validation should include:
+
+- JavaScript syntax checks for global and workspace endpoint editors.
+- Functional regression coverage for the New Foundry API version default, `/v1` query omission behavior, and setup copy.
+- Optional authenticated Playwright UI coverage for the Admin Settings endpoint modal.
+
+Before this fix, users could follow unclear UI and docs guidance and choose incompatible API-version values for non-OpenAI New Foundry models. The runtime could also silently save a blank assistant message if a provider completed a stream without normal assistant text. After this fix, the default and guidance keep Foundry project inference on endpoint default `v1`, the runtime omits invalid `api-version` query values for `/openai/v1`, and empty provider streams retry once without streaming before surfacing a clear endpoint-compatibility error.
+
+Version reference: `application/single_app/config.py` is at **0.250.006** for this fix.

+# Personal Workspace Plugin Stepper Modal Fix
+
+Fixed/Implemented in version: **0.250.032**
+
+## Issue Description
+
+The personal workspace could throw `Cannot read properties of null (reading 'addEventListener')` from `plugin_modal_stepper.js` when user actions were disabled or unavailable by governance. The plugin modal markup was conditionally rendered, but the shared plugin stepper module was still loaded unconditionally near the end of the workspace page.
+
+The personal document delete modal could also emit a browser accessibility warning because the focused delete button remained inside the modal while Bootstrap applied `aria-hidden` during hide.
+
+## Root Cause Analysis
+
+- `workspace.html` used the correct governance check when including `_plugin_modal.html`, but did not use the same check for `plugin_modal_stepper.js`.
+- `plugin_modal_stepper.js` created `PluginModalStepper` immediately and `bindEvents()` assumed modal controls such as `#plugin-modal-next` existed.
+- `workspace-documents.js` hid the delete modal directly from button click handlers without first releasing focus from the clicked modal button.

+- The stepper module now checks for `#plugin-modal` before creating the global `window.pluginModalStepper` instance.
+- The personal document delete modal now blurs focused modal descendants before hiding.
+
+## Validation
+
+- Added a functional regression test that verifies script gating and defensive stepper initialization.
+- Updated UI coverage for the personal document delete modal focus handoff.
+- Ran JavaScript syntax checks and targeted pytest coverage for the changed tests.

+# Plugin Tool And Agent Security Audit Fix
+
+Fixed/Implemented in version: **0.242.056**
+
+## Issue Description
+
+The plugin/tool/agent security audit found that resolved action credentials and sensitive tool payload fields could be echoed into plugin invocation logs, chat citations, workflow citations, and OpenAPI diagnostic/error payloads after runtime secret resolution.
+
+## Root Cause Analysis
+
+Plugin invocation records stored raw parameters, results, and errors, and browser-facing log APIs serialized those records directly. Chat and workflow citation builders also copied raw invocation fields into assistant citation payloads. The OpenAPI plugin logged request headers, query parameters, resolved request URLs, and error payloads without redacting API keys, bearer tokens, basic credentials, or secret-bearing query strings. SimpleChat group helper fallback also read `activeGroupOid` directly instead of using the shared active-group authorization helper.

+# Plugin Validation Route Auth Fix
+
+Fixed/Implemented in version: **0.241.206**
+
+## Issue Description
+
+Several plugin validation endpoints did not consistently enforce the runtime authentication and role decorators used by comparable SimpleChat API routes. The admin-namespaced validation helper routes could execute without `@login_required` and `@admin_required`, while the user-facing validation route only required login and did not require the standard user role boundary.
+
+## Root Cause Analysis
+
+`@swagger_route(security=get_auth_security())` documents the OpenAPI security requirement but does not enforce request authentication at runtime. Runtime enforcement in SimpleChat is provided by route decorators from `functions_authentication.py`, such as `@login_required`, `@user_required`, and `@admin_required`.
+
+The affected routes in `application/single_app/plugin_validation_endpoint.py` had incomplete decorator stacks compared with nearby plugin routes in `application/single_app/route_backend_plugins.py`.
+
+## Technical Details
+
+Files modified:
+
+- `application/single_app/plugin_validation_endpoint.py`
+- `application/single_app/config.py`
+- `functional_tests/test_plugin_validation_route_auth.py`
+- `.github/prompts/route-authentication-audit.prompt.md`
+- `.github/workflows/broken-access-control-check.yml`
+- `functional_tests/test_broken_access_control_guardrails_checker.py`
+
+Code changes summary:
+
+- Added `@user_required` to the user-facing `/api/plugins/validate` route.
+- Added `@login_required` and `@admin_required` to the admin plugin instantiation, health-check, and repair routes.
+- Added a route-authentication audit prompt for broader Flask route decorator reviews.
+- Wired the route-authentication audit prompt into the Broken Access Control guardrail workflow path list.
+- Added a focused functional regression test for the plugin validation route auth contract.
+- Updated `config.py` version to `0.241.206`.
+
+## Testing Approach
+
+Validation includes a static functional test that parses `plugin_validation_endpoint.py` and asserts the exact expected runtime auth decorators for each plugin validation route. This catches future accidental removal of `@login_required`, `@user_required`, or `@admin_required` without needing to execute state-changing plugin repair logic.
+
+## Impact Analysis
+
+After the fix:
+
+- Anonymous callers are blocked before reaching plugin validation admin logic.
+- Non-admin authenticated users are blocked from admin plugin validation operations.
+- User-facing plugin manifest validation follows the same user-role boundary as similar plugin helper APIs.
+- A reusable route-auth audit prompt is available for broader review of existing Flask route decorator coverage.
+
+## Validation
+
+Before the fix, a static decorator review showed the three admin plugin validation routes had no runtime auth decorators and the user-facing validation route was login-only.
+
+After the fix, the expected contract is:
+
+- `/api/plugins/validate`: `@login_required`, `@user_required`
+- `/api/admin/plugins/validate`: `@login_required`, `@admin_required`
+- `/api/admin/plugins/test-instantiation`: `@login_required`, `@admin_required`
+- `/api/admin/plugins/health-check/<plugin_name>`: `@login_required`, `@admin_required`
+- `/api/admin/plugins/repair/<plugin_name>`: `@login_required`, `@admin_required`

+# Privacy Logging And Telemetry Audit Fix
+
+Fixed/Implemented in version: **0.242.058**
+
+## Issue Description
+
+The privacy logging and telemetry audit found several diagnostic paths that could copy sensitive payloads into logs or processing activity records. The affected payloads included plugin parameters, plugin result samples, multi-agent message content, document chunk text, full document metadata, and raw vision model response text.
+
+## Root Cause Analysis
+
+Some logging paths favored full diagnostic payloads instead of minimized telemetry. Plugin decorator logs emitted raw parameter dictionaries and result previews, agent orchestrator callbacks logged full response content, and document-processing activity records included uploaded document text or full metadata for troubleshooting.
+
+## Technical Details
+
+Files modified:
+
+- `application/single_app/functions_appinsights.py`
+- `application/single_app/semantic_kernel_plugins/plugin_invocation_logger.py`
+- `application/single_app/agent_orchestrator_groupchat.py`
+- `application/single_app/agent_orchestrator_magnetic.py`
+- `application/single_app/functions_documents.py`
+- `application/single_app/config.py`
+- `functional_tests/test_privacy_logging_telemetry_audit.py`
+
+Code changes summary:
+
+- Added central `log_event(...)` redaction for secret-bearing keys, Authorization values, connection strings, tokens, API keys, and SAS-style signatures while preserving general telemetry volume.
+- Changed plugin decorator parameter logs to record names, counts, and value shapes instead of raw values.
+- Redacted plugin JSON serialization, replaced raw plugin result previews with type/key/length summaries, and removed tabular result value samples from structured telemetry summaries.
+- Changed group chat and Magentic agent orchestration logs to record agent names, roles, message types, and content lengths instead of full message content.
+- Replaced document-processing task logs that contained raw query results, chunk text, metadata JSON, or vision response text with counts and lengths.
+
+## Validation
+
+Testing approach:
+
+- Added `functional_tests/test_privacy_logging_telemetry_audit.py` to validate redaction helpers and source-level guardrails for the audited logging patterns.
+- Updated version-pinned functional tests to match the current `config.py` version.
+
+Before/after comparison:
+
+- Before: diagnostics could store raw uploaded text, full agent responses, plugin parameters, tabular value samples, or secret-bearing fields.
+- After: diagnostics keep event names, IDs, counts, shapes, lengths, timings, and status while redacting credentials and minimizing private content payloads.
+
+Related version update:
+
+- `application/single_app/config.py` was incremented to `0.242.058`.

+# Profile Feedback Table Overflow Fix
+
+Fixed in version: **0.241.034**
+
+## Issue Description
+
+The profile My Feedback table could show a horizontal scrollbar because it included wide AI response and admin action columns in the list view. Those fields made the table difficult to scan and pushed the row beyond the available card width.
+
+## Root Cause Analysis
+
+- The feedback table rendered eight columns, including long-form AI response and admin action text.
+- The table used the generic responsive wrapper, so overflow appeared as a horizontal scrollbar instead of keeping the row inside the profile card.
+- Prompt, reason, response, and action cells all used truncation-oriented styles, which still preserved enough column width to make the table exceed the view.
+
+## Technical Details
+
+### Files Modified
+
+- `application/single_app/templates/profile.html`
+- `application/single_app/static/js/profile/profile-tabs.js`
+- `application/single_app/config.py`
+- `functional_tests/test_profile_feedback_table_overflow_fix.py`
+- `ui_tests/test_profile_feedback_table_no_scroll.py`
+
+### Code Changes Summary
+
+- Removed AI Response and Admin Action from the visible My Feedback table columns.
+- Kept AI response and admin action values available in the Feedback Details modal.
+- Added a profile-feedback-specific fixed table layout with wrapping cells and a non-scrolling wrapper.
+- Updated feedback table loading, empty, and error row colspans to match the compact six-column table.
+
+## Testing Approach
+
+- Added `functional_tests/test_profile_feedback_table_overflow_fix.py` to validate the compact table contract, six-column colspans, version bump, and retained modal details.
+- Added `ui_tests/test_profile_feedback_table_no_scroll.py` to mock feedback API responses, verify the compact column set, assert the table wrapper does not overflow horizontally, and confirm full details remain available from the modal.
+
+## Validation
+
+### Test Results
+
+- JavaScript syntax checks passed for the updated profile renderer.
+- Python compile checks passed for the new functional and UI tests.
+- `functional_tests/test_profile_feedback_table_overflow_fix.py` passes locally.
+- The UI regression test was added but requires `SIMPLECHAT_UI_BASE_URL` and `SIMPLECHAT_UI_STORAGE_STATE` to run in an authenticated environment.
+
+### User Experience Improvements
+
+- The My Feedback list view now fits within the profile page card without a horizontal scrollbar.
+- Users can scan timestamp, prompt, feedback, reason, acknowledgement, and details without wide administrative fields crowding the table.
+- Full AI response and admin action information remains accessible from the row Details view.

+# Profile Last Login Activity Log Fix
+
+Fixed/Implemented in version: **0.241.027**
+
+Related config update: `application/single_app/config.py` now sets `VERSION = "0.241.027"`.
+
+## Issue Description
+
+The profile page hero displayed `Last Login` from cached user metrics stored in user settings. Those metrics are refreshed separately from live authentication activity, so the profile value could lag behind the current chat session and the actual `user_login` records in `activity_logs`.
+
+## Root Cause Analysis
+
+- The profile page loaded `/api/user/settings` and read `settings.metrics.login_metrics.last_login` directly.
+- That value came from the metrics refresh/cache path, not the live `activity_logs` source used by login activity charts and audit reporting.
+- The profile hero is a current-activity signal, so it should not depend on refreshed aggregate metrics.
+
+## Technical Details
+
+Files modified:
+
+- `application/single_app/functions_activity_logging.py`
+- `application/single_app/route_frontend_profile.py`
+- `application/single_app/templates/profile.html`

+- `functional_tests/test_profile_last_login_activity_logs.py`
+- `ui_tests/test_profile_last_login_activity_log_badge.py`
+
+Code changes summary:
+
+- Added `get_user_login_activity_summary(...)` to read login activity from the `activity_logs` container using the user's `/user_id` partition.
+- Updated the profile settings API response to overlay `metrics.login_metrics.last_login` from activity logs before returning data to the profile page.
+- Kept cached aggregate metrics, including total logins and chat/document totals, unchanged.
+- Added a response-only `last_login_source` marker of `activity_logs` for the overlaid profile value.
+- Updated the profile badge to show `Never` when activity logs contain no login record instead of leaving the placeholder text visible.
+
+Testing approach:
+
+- Added a dependency-free functional regression test with a fake activity log container.
+- Covered newest-login selection across `timestamp` and `created_at` fields.
+- Covered profile settings response overlay behavior and confirmed the cached settings document is not mutated.
+- Added a Playwright UI regression test for the empty activity-log fallback shown in the profile hero.
+
+## Validation
+
+Before:
+
+- The profile hero could show an older last-login date from refreshed cached metrics.
+- Clearing or aging the metrics cache changed the displayed profile value even when activity logs had a newer login.
+
+After:
+
+- The profile hero receives last-login data from the live `activity_logs` lookup.
+- Cached aggregate metrics remain available for total counts and the existing metrics calculated-date note.
+- If activity logs contain no login record, the response clears the stale cached last-login value instead of presenting it as current activity.

+# Profile Safety Category Tags Fix - v0.241.036
+
+Fixed in version: **0.241.036**
+
+## Issue Description
+
+The profile Violations tab displayed triggered content safety categories as a comma-separated text list such as `Hate(s=0), SelfHarm(s=0), Sexual..., Violence...`. Categories with a score below 1 were still visible, which made inactive safety categories look like triggered findings.
+
+## Root Cause Analysis
+
+The profile tab formatted every stored `triggered_categories` entry as plain text without applying the severity filtering already used by the admin safety review UI. The table and detail modal both reused that comma-separated formatter.
+
+## Version Implemented
+
+Implemented in version: **0.241.036**
+
+The application version is tracked in `application/single_app/config.py` and now reads `0.241.036` for this code change.
+
+## Technical Details
+
+Files modified:
+
+- `application/single_app/static/js/profile/profile-tabs.js`
+- `application/single_app/config.py`
+- `ui_tests/fixtures/profile_violations_harness.html`
+- `ui_tests/test_profile_violations_category_badges.py`
+
+Code changes summary:
+
+- Added profile-side safety category normalization that keeps only categories with severity scores from 1 through 4.
+- Rendered the remaining categories as Bootstrap badge tags in the profile violations table.
+- Rendered the same filtered badge tags in the View/Edit violation detail modal.
+- Added a focused Playwright regression harness for profile violation category rendering.
+
+## Testing Approach
+
+- Added a UI regression test that serves a static profile harness and mocks the safety log API response.
+- The test verifies that `Hate` with severity `0` is hidden while `Violence` with severity `2` and `SelfHarm` with severity `4` render as badge tags in both the table and detail modal.
+
+## Impact Analysis
+
+Users now see only categories that actually crossed the visible threshold, presented as compact tags instead of a dense comma-separated list. This aligns the profile experience with the admin safety review page and reduces confusion when reviewing personal safety violations.
+
+## Validation
+
+Before:
+
+- All stored category entries were shown as plain comma-separated text.
+- Severity `0` categories appeared even though they were not active findings.
+
+After:
+
+- Only severity `1` through `4` categories render.
+- Each visible category appears as an individual badge tag in the table and detail modal.

+# PR Readiness Guardrail Cleanup Fix
+
+Fixed/Implemented in version: **0.242.065**
+
+## Issue Description
+
+The beta branch had PR-readiness blockers in local validation: trailing whitespace in changed files, one unnecessary `|safe` filter on JSON-rendered Admin Settings data, a UTF-8 BOM that prevented broken-access-control parsing, and new Semantic Kernel plugin surfaces that needed explicit guardrail justifications for delegated current-user authorization helpers.
+
+## Root Cause Analysis
+
+The branch accumulated broad feature work across backend, frontend, documentation, and tests. A few hygiene and guardrail details were left in the final diff even though the underlying behaviors already delegated to current-user service helpers for authorization.
+
+## Technical Details
+
+Files modified:
+
+* `application/single_app/config.py`
+* `application/single_app/templates/admin_settings.html`
+* `application/single_app/semantic_kernel_loader.py`
+* `application/single_app/semantic_kernel_plugins/document_search_plugin.py`
+* `application/single_app/semantic_kernel_plugins/msgraph_plugin.py`
+* `application/single_app/semantic_kernel_plugins/simplechat_plugin.py`
+* Whitespace-only cleanup in changed README, docs, CSS, JS, HTML, and Python files
+
+Code changes summary:
+
+* Removed trailing whitespace from changed files reported by `git diff --check`.
+* Removed an unnecessary Jinja `|safe` filter where `tojson` already provides the safe JSON serialization boundary.
+* Removed a UTF-8 BOM from `semantic_kernel_loader.py` so AST-based validation can parse it.
+* Added narrow `bac-check: ignore` justifications where plugin methods delegate authorization to service-layer current-user helpers.
+* Updated `config.py` to version `0.242.065`.
+
+## Validation
+
+Test results:
+
+* `git diff --check origin/Development` passes after cleanup.
+* Python compile and Swagger route validation pass against the current worktree.
+* Targeted full-file broken-access-control validation passes for the edited plugin and loader files.
+* First-party changed JavaScript syntax validation passes with `node --check`.
+
+Before/after comparison:
+
+* Before: PR validation reported whitespace, XSS guardrail, BAC parser, and plugin scope guardrail blockers.
+* After: the touched files pass targeted validation, and the branch has a release-note entry for the cleanup.
+
+User experience improvements:
+
+* Maintainers get a cleaner draft PR with fewer avoidable CI failures and clearer security-review notes.
+
+Reference: `config.py` version updated to `0.242.065` as part of this fix.

+# Public Workspace Creation Auth Binding Fix - v0.241.039
+
+Fixed in version: **0.241.039**
+
+## Issue Description
+
+Users could not create public workspaces from the Create Public Workspace modal. The API returned an error containing `name 'get_current_user_info' is not defined`, so the modal displayed the backend exception instead of creating the workspace.
+
+## Root Cause Analysis
+
+`functions_public_workspaces.py` imported authentication helpers with `from functions_authentication import *` and then called `get_current_user_info()` as a module-level snapshot. During full Flask app startup, circular imports can load `functions_public_workspaces.py` while `functions_authentication.py` is still only partially initialized. In that import order, the star import does not bind `get_current_user_info`, and later calls to `create_public_workspace()` fail with `NameError`.
+
+## Version Implemented
+
+Implemented in version: **0.241.039**
+
+The application version was updated in `application/single_app/config.py` from `0.241.038` to `0.241.039` for this code change.
+
+## Technical Details
+
+Files modified:
+
+- `application/single_app/functions_public_workspaces.py`
+- `application/single_app/config.py`
+- `functional_tests/test_public_workspace_auth_helper_import_order_fix.py`
+- `docs/explanation/fixes/PUBLIC_WORKSPACE_CREATION_AUTH_BINDING_FIX.md`
+
+Code changes summary:
+
+- Replaced the public workspace helper's authentication star import with a live `functions_authentication` module import.
+- Updated `create_public_workspace()` to call `functions_authentication.get_current_user_info()` so it resolves the current helper at runtime.
+- Added functional regression coverage for full app import order and session-backed public workspace creation.
+
+## Testing Approach
+
+- Added a functional test that imports the full Flask app path, verifies the public workspace helper can still reach `get_current_user_info`, and creates a public workspace with a stubbed Cosmos container write.
+- Compiled the changed Python files to catch syntax and import-shape errors.
+
+## Impact Analysis
+
+Public workspace creation now uses the same import-order-safe authentication pattern as group workspace creation. Users with permission to create public workspaces can create them from the modal without hitting the missing `get_current_user_info` binding.
+
+## Validation
+
+Before:
+
+- Public workspace creation could fail with `name 'get_current_user_info' is not defined` after full app startup.
+- The modal surfaced the backend exception and no workspace was created.
+
+After:
+
+- `create_public_workspace()` resolves the current user through the live authentication module.
+- The regression test verifies the full app import path and session user ownership assignment.

+# Public Workspace Manage Asset Versioning Fix (v0.242.058)
+
+Fixed/Implemented in version: **0.242.058**
+
+Related config.py version update: `application/single_app/config.py` now sets `VERSION = "0.242.058"`.
+
+## Issue Description
+
+Users could continue seeing `Uncaught SyntaxError: Unexpected token '&'` from `manage_public_workspace.js` after the earlier script syntax fix had already landed. The current source parses cleanly, but the Manage Public Workspace template requested the script without an application-version query string, allowing browsers or intermediate caches to reuse an older broken copy after deployment.
+
+## Root Cause Analysis
+
+The referenced `&bull;` line in the current script is valid JavaScript because it is inside a template literal. The previous syntax fix removed malformed fragments that caused the parser to report the ampersand as the failing token, but the page still loaded `manage_public_workspace.js` from an unversioned URL. That made stale client-side assets a plausible path for the same browser error to persist for individual users.
+
+## Technical Details
+
+### Files Modified
+
+- `application/single_app/templates/manage_public_workspace.html`
+- `application/single_app/config.py`
+- `functional_tests/test_public_workspace_manage_asset_versioning.py`
+- `ui_tests/test_public_workspace_manage_script_parse.py`
+- `docs/explanation/fixes/PUBLIC_WORKSPACE_MANAGE_ASSET_VERSIONING_FIX.md`
+
+### Code Changes Summary
+
+- Added `?v={{ config['VERSION'] }}` to the `manage_public_workspace.js` script URL.
+- Bumped `config.py` to `0.242.058` so the deployed script URL changes.
+- Added source-level regression coverage for the versioned script reference and retained parser checks for the current JavaScript.
+
+## Validation
+
+### Testing Approach
+
+- Verified `manage_public_workspace.js` parses cleanly with Node.js.
+- Added a functional regression that confirms the template no longer contains the unversioned script URL.
+- Extended the UI parser regression to check the same cache-busting contract.
+
+### Before/After Comparison
+
+- Before: browsers could request `/static/js/public/manage_public_workspace.js` and reuse an old cached copy.
+- After: browsers request `/static/js/public/manage_public_workspace.js?v=0.242.058`, forcing a fresh asset URL after deployment.

+# Python 3.12 CI and XSS Guardrail Fix
+
+Fixed/Implemented in version: **0.242.066**
+
+## Issue Description
+
+GitHub PR checks were failing because workflow jobs used Python 3.11 while SimpleChat targets Python 3.12. The branch also had changed browser-rendering lines that triggered the XSS sink guardrail.
+
+## Root Cause Analysis
+
+Python 3.11 rejects f-string forms that Python 3.12 accepts, so syntax-sensitive guardrail jobs could not parse valid app code. Separately, the XSS checker flagged changed template lines that used `|safe`, dynamic `innerHTML`, or interpolated image markup instead of explicit JSON/DOM boundaries.

+
+Code changes summary:

+* Updated workflow Python setup to `3.12`.
+* Removed an unnecessary `|safe` filter from `tojson`-rendered Admin Settings data.
+* Replaced group delete modal dynamic HTML insertion with DOM construction and `textContent`.

+* Python 3.12 compile validation passes for changed application Python files.
+* XSS sink validation passes for the changed application browser-rendering surfaces.
+* First-party JavaScript syntax validation passes for the changed template-adjacent JavaScript files.
+
+Before/after comparison:
+
+* Before: CI syntax and parser-based guardrail jobs failed under Python 3.11, and XSS guardrail jobs flagged changed rendering lines.
+* After: CI uses the supported Python 3.12 runtime, and changed rendering code uses explicit safe JSON/DOM boundaries.
+
+User experience improvements:
+
+* Maintainers get PR checks aligned with the supported runtime while retaining XSS guardrail coverage for browser-rendering changes.
+
+Reference: `config.py` version updated to `0.242.066` as part of this fix.

+# Rendered Markdown Message Masking Fix
+
+Fixed/Implemented in version: **0.250.029**
+
+## Issue Description
+
+Selected-text masking could fail with `Selection no longer matches the stored message content` when users selected text from rendered assistant responses, especially Markdown tables and bolded summary text.
+
+## Root Cause Analysis
+
+The browser calculated selection offsets from the rendered `.message-text` content, while the backend validated those offsets against the raw stored Markdown. Formatting characters such as `**` and Markdown table separators changed the visible text positions, so valid user selections were rejected.
+
+## Technical Details
+
+Files modified:
+
+* `application/single_app/functions_message_masking.py`
+* `application/single_app/static/js/chat/chat-messages.js`
+* `application/single_app/config.py`
+* `functional_tests/test_chat_layered_message_masking.py`
+* `docs/explanation/features/MESSAGE_LAYERED_MASKING.md`
+
+Code changes summary:
+
+* Added a conservative Markdown-to-visible-text projection fallback for selection validation.
+* Preserved canonical `start` and `end` offsets for model-history masking.
+* Added optional `display_start`, `display_end`, and `display_text` range metadata for browser-side rendered highlighting.
+* Updated the chat client to send display offsets and prefer them when wrapping masked ranges in the rendered DOM.
+
+## Validation
+
+Test coverage validates:
+
+* Existing layered mask state transitions.
+* Rendered bold Markdown selections mapping back to raw stored Markdown.
+* Rendered Markdown table cell selections mapping back to canonical table source.
+* Frontend payload and display-offset wrapping contract.
+
+Before the fix, formatted rendered selections could be rejected with a 400 response. After the fix, selected rendered text is accepted when it maps uniquely to the stored message content, while ambiguous duplicate selections are still rejected.
+
+Related version update: `application/single_app/config.py` was incremented to `0.250.029`.

+# Route Authentication Audit Findings Fix
+
+Fixed in version: **0.242.050**
+
+## Issue Description
+
+The route authentication audit found several route-contract gaps where Swagger metadata, runtime role decorators, external API token checks, or object-level active-scope authorization patterns were incomplete or inconsistent.
+
+## Root Cause Analysis
+
+Several older route modules had grown independently and still relied on `@login_required` alone for user-facing API routes. Some public workspace and collaboration handlers also read stored active-scope settings directly instead of using the shared authorization helpers. The agent-template routes had valid runtime role protection, but their Swagger metadata decorator was below runtime decorators, which violates the repository route contract.
+
+## Version Implemented
+
+0.242.050
+
+## Technical Details
+
+### Files Modified
+
+- `application/single_app/route_backend_agents.py`
+- `application/single_app/route_backend_agent_templates.py`
+- `application/single_app/route_backend_plugins.py`
+- `application/single_app/route_backend_speech.py`

+- `application/single_app/route_backend_collaboration.py`
+- `application/single_app/config.py`
+- `functional_tests/test_route_authentication_audit_findings_fix.py`
+
+### Code Changes Summary
+
+- Added `@user_required` after `@login_required` on audited non-admin application API routes.
+- Added `@accesstoken_required` to the external public document delete route.
+- Reordered agent-template Swagger decorators to immediately follow the Flask route decorator.
+- Added Swagger auth metadata to the no-auth health probe while preserving its public runtime behavior.
+- Replaced raw `activePublicWorkspaceOid` reads in public document routes with `require_active_public_workspace(...)`.
+- Replaced the collaboration group fallback `activeGroupOid` read with `require_active_group(...)`.
+- Updated `config.py` from `0.242.049` to `0.242.050`.
+
+### Testing Approach
+
+The regression test statically parses the route modules and verifies the decorator order, runtime role decorator coverage, external token guard, active-scope helper usage, and version bump.
+
+## Validation
+
+### Test Results
+
+- `functional_tests/test_route_authentication_audit_findings_fix.py`
+- `scripts/check_swagger_routes.py`
+- `scripts/check_broken_access_control.py --full-file`
+
+### Before and After Comparison
+
+Before the fix, the audit scripts reported misplaced or missing Swagger metadata, direct active-scope reads, and route stacks with only `@login_required`. After the fix, the affected routes use the expected runtime decorators and shared object-level authorization helpers.
+
+### User Experience Improvements
+
+Users with authenticated sessions but without the `User` or `Admin` role are blocked consistently from user-facing API routes. Public workspace and collaboration operations now revalidate active scope before sensitive reads or mutations, reducing stale-scope and cross-scope authorization risk.

+# Scope Lock Agent Unlock Fix
+
+Fixed in version: **0.241.052**
+
+## Issue Description
+
+After unlocking a conversation scope, workspace documents and prompts became broadly available again, but the agent pickers still behaved as if the conversation was locked to its original workspace context. That left valid personal or group agents hidden or unavailable even though the scope unlock had already succeeded.
+
+## Root Cause Analysis
+
+- The main chat agent dropdown still applied its existing-conversation metadata guard whenever a conversation had a concrete `data-chat-type`, even after `scope_locked` had been explicitly set to `false`.
+- The scope lock toggle refreshed documents and tags, but it never dispatched the shared scope-change event that the agent dropdown listens to for rebuilds.
+- The retry modal duplicated similar conversation-scope filtering, so it could also keep agents locked out after an explicit unlock.
+
+## Version Implemented
+
+- **0.241.052**
+
+## Files Modified
+
+- `application/single_app/static/js/chat/chat-documents.js`
+- `application/single_app/static/js/chat/chat-agents.js`
+- `application/single_app/static/js/chat/chat-retry.js`
+- `application/single_app/config.py`
+- `functional_tests/test_scope_lock_agent_unlock_fix.py`
+
+## Code Changes Summary
+
+- Added a shared explicit-unlock guard in `chat-agents.js` so existing conversations only force conversation-type agent filtering while the scope is still locked or auto-scoped.
+- Updated `toggleScopeLock(...)` in `chat-documents.js` to run the normal scope refresh pipeline and notify listeners with `chat:scope-changed` after lock or unlock.
+- Updated the retry modal agent loader to respect the explicit unlock state and include agents from the currently effective scope selections.
+
+## Testing Approach
+
+- Added `functional_tests/test_scope_lock_agent_unlock_fix.py`.
+- The regression verifies the main agent picker unlock guard, the post-toggle scope refresh dispatch, the retry picker unlock handling, and version/documentation alignment.
+
+## Impact Analysis
+
+- Explicitly unlocked conversations now refresh agent availability immediately instead of leaving the picker in a stale locked state.
+- Agent availability now matches the effective workspace scope after unlock, which keeps agents aligned with documents and prompts.
+- Retry workflows use the same unlock-aware agent filtering, reducing inconsistencies between the main composer and retry modal.
+
+## Validation
+
+- Before: unlocking scope restored documents and prompts but left many agent options hidden or disabled because the agent UI still enforced the original conversation workspace.
+- After: explicit unlocks trigger a scope refresh event and both agent pickers honor the unlocked effective scope instead of the stale conversation-only guard.

+# Scope Lock Collaboration Unlock Fix
+
+Fixed in version: **0.241.051**
+
+## Issue Description
+
+The chat scope lock modal could fail to unlock a collaborative conversation even though the same conversation was otherwise active and accessible in the UI. The browser console showed a 404 on `/api/conversations/<conversation_id>/scope_lock` with the backend response `Conversation not found`.
+
+## Root Cause Analysis
+
+- The shared scope lock route only read from `cosmos_conversations_container`, which covers standard single-user chat conversations.
+- Collaborative conversations live in `cosmos_collaboration_conversations_container`, so collaboration ids bypassed the normal lookup and fell straight into the 404 path.
+- Even if the collaboration document were updated independently, the hidden source conversation used for mirrored AI responses also needed to stay synchronized for future stream and export flows.
+
+## Version Implemented
+
+- **0.241.051**
+
+## Files Modified
+
+- `application/single_app/route_backend_conversations.py`
+- `application/single_app/config.py`
+- `functional_tests/test_scope_lock_collaboration_unlock_fix.py`
+
+## Code Changes Summary
+
+- Added a scope-lock conversation resolver that first checks the standard conversation container and then falls back to collaborative conversations.
+- Reused collaboration authorization so accepted participants can toggle scope lock without weakening access checks.
+- Synced scope lock updates back into the hidden source conversation metadata so collaborative AI response mirroring keeps the same `scope_locked` and `locked_contexts` state.
+
+## Testing Approach
+
+- Added `functional_tests/test_scope_lock_collaboration_unlock_fix.py`.
+- The regression checks the collaboration fallback path, the preserved `locked_contexts` response contract, and version/documentation alignment.
+
+## Impact Analysis
+
+- Unlocking and re-locking scope now works for collaborative conversations instead of failing with a false 404.
+- Existing single-user conversation behavior remains unchanged.
+- Collaborative metadata stays consistent between the visible collaboration conversation and its hidden source conversation.
+
+## Validation
+
+- Before: collaborative scope unlock requests returned `Conversation not found` from the shared scope lock route.
+- After: the route resolves collaborative conversations, updates the collaboration record, syncs the source conversation, and returns the expected success payload.

+# Semantic Search Quota Warning Fix
+
+Fixed in version: **0.241.086**
+
+## Issue Description
+
+When Azure AI Search returned the monthly free Semantic Ranker quota error, workspace search could fail without a visible warning. In streaming chat, the failure path could continue with no search results and later report `augmentation_message_count: 0`, making selected-document search look like an upload or processing problem.
+
+## Root Cause Analysis
+
+The Azure AI Search semantic quota error was not classified separately from other search exceptions. One chat path returned a generic embedding error, while the streaming path logged the search error and continued without augmentation. The frontend workspace and admin pages had no shared service-health signal to show that Semantic Ranker quota was exhausted.
+
+## Version Implemented
+
+Implemented in version: **0.241.086**
+
+## Technical Details
+
+Files modified:
+
+- `application/single_app/functions_service_health.py`
+- `application/single_app/functions_search.py`
+- `application/single_app/route_backend_chats.py`
+- `application/single_app/functions_settings.py`
+- `application/single_app/templates/_semantic_search_health_warning.html`
+- Workspace templates and admin templates that include the warning partial
+- `application/single_app/config.py`
+
+Code changes summary:
+
+- Added a semantic-search service-health helper that detects free Semantic Ranker usage exhaustion.
+- Persisted a sanitized `service_health.semantic_search` warning in app settings when the quota error is detected.
+- Clear the warning after a later semantic search succeeds.
+- Return a typed chat warning instead of a generic embedding error for non-streaming chat.
+- Stop streaming chat after emitting a visible warning instead of silently continuing with no augmentation.
+- Render a warning banner on personal, group, public, and managed public workspace pages, plus Admin Settings and Control Center.
+
+## Testing Approach
+
+- Added `functional_tests/test_semantic_search_quota_warning.py` for backend detection, chat response wiring, template inclusion, and version consistency.
+- Added `ui_tests/test_semantic_search_health_warning.py` to render the warning partial with Playwright and verify settings-backed text remains escaped.
+
+## Impact Analysis
+
+Users now see a clear workspace search warning after the app detects exhausted free Semantic Ranker usage. Admins see the same warning with the recommended action to upgrade Semantic Ranker to Standard or wait for the monthly free quota reset. This makes the issue visible at the workspace/admin level instead of appearing as missing document augmentation.
+
+## Validation
+
+Before:
+
+- Semantic quota errors could be logged but hidden from users.
+- Streaming chat could proceed with zero document augmentation.
+- Workspace and admin pages did not show a service-health warning.
+
+After:
+
+- Semantic quota exhaustion is recorded as service health.
+- Chat returns or streams a user-visible warning.
+- Workspace and admin pages render the warning until a successful semantic search clears it.

+# Settings Secrets Exposure Hardening Fix
+
+Fixed/Implemented in version: **0.242.059**
+
+## Issue Description
+
+The Settings and Secrets Exposure audit found three places where secret-bearing values or service diagnostics could be exposed more broadly than needed:
+
+- Admin Settings rendered stored keys, client secrets, subscription keys, and connection strings into password input values.
+- Admin Settings test buttons depended on those raw DOM values for connection tests, making simple blanking unsafe without breaking tests.
+- The Azure Billing community action logged token endpoint details and response bodies on service-principal token failures.
+- The TTS route returned raw SDK/configuration exception detail to authenticated clients.
+
+## Root Cause Analysis
+
+Admin Settings loaded raw settings for admin functionality and passed them to the template. Although the route is admin-only, password inputs still made stored values browser-inspectable. Test-connection requests were built from current input values, so removing secrets from the DOM required a server-side way to resolve a stored sentinel. Azure Billing used direct `logging.error(...)` with token response text, and TTS returned raw exception strings from Azure Speech SDK paths.
+
+## Technical Details
+
+### Files Modified
+
+- `application/single_app/functions_settings.py`
+- `application/single_app/route_frontend_admin_settings.py`
+- `application/single_app/route_backend_settings.py`
+- `application/community_customizations/actions/azure_billing_retriever/azure_billing_plugin.py`
+- `application/single_app/route_backend_tts.py`
+- `application/single_app/config.py`
+- `functional_tests/test_settings_secrets_exposure_hardening.py`
+
+### Code Changes Summary
+
+- Added `ADMIN_SETTINGS_SECRET_REDACTED_VALUE` and shared Admin Settings redaction/preservation helpers.
+- Redacted stored Admin Settings secrets before rendering the admin template.
+- Preserved existing stored values when Admin Settings POST submits the redacted sentinel.
+- Resolved the same sentinel in `/api/admin/settings/test_connection` so tests continue to work without re-entering secret values.
+- Replaced Azure Billing token-failure raw logging/raised response details with `log_event(...)` and generic user-facing failures.
+- Replaced TTS raw client-facing SDK/configuration exception responses with stable generic messages while logging sanitized details server-side.
+- Updated application version from `0.242.058` to `0.242.059` in `config.py`.
+
+## Validation
+
+### Test Results
+
+Focused validation is covered by `functional_tests/test_settings_secrets_exposure_hardening.py`, which checks:
+
+- Admin Settings secret fields are registered for redaction.
+- Admin saves use the preservation helper instead of direct raw secret assignment.
+- Admin test-connection payloads resolve stored sentinel values server-side.
+- Azure Billing token errors no longer include token endpoint response details in logs or raised exceptions.
+- TTS client-facing failures no longer return raw exception strings.
+
+### Before/After Comparison
+
+Before: Stored secrets were available in Admin Settings browser markup, and some external-service failures exposed raw provider diagnostics.
+
+After: Admin Settings renders a redacted sentinel for stored secret-bearing fields, test/save flows resolve that sentinel back to the stored value server-side, and external-service failures return generic client messages with sanitized diagnostic logging.
+
+## Impact Analysis
+
+Admins can still test configured services without re-entering keys, secrets, or connection strings. Blank secret fields still clear values intentionally, while `***REDACTED***` means preserve the stored value. Non-admin settings rendering remains unchanged and continues to use public settings sanitization.

+# SimpleChat Action Validation Fix
+
+Fixed/Implemented in version: **0.241.023**
+
+## Overview
+
+The workspace Add Action flow could fail when saving the built-in SimpleChat action even though the modal no longer asked for a URL. The browser validation step posted to an admin-only endpoint, and the backend validation path still treated SimpleChat like a generic endpoint-based plugin.
+
+## Root Cause
+
+- Shared browser-side validation in `plugin_common.js` always called `/api/admin/plugins/validate`, which returned `403` for normal workspace users.
+- The shared JSON validation helper still enforced a user-provided endpoint for non-SQL plugins unless the calling code had already injected runtime defaults.
+- The server-side pre-save validation route did not apply built-in plugin defaults before running manifest health checks.
+
+## Files Modified
+
+- `application/single_app/static/js/plugin_common.js`
+- `application/single_app/json_schema_validation.py`
+- `application/single_app/plugin_validation_endpoint.py`
+- `functional_tests/test_plugin_validation_managed_fields_compatibility.py`
+- `ui_tests/test_workspace_simplechat_action_modal.py`
+
+## Code Changes Summary
+
+1. Switched shared browser validation to use a generic authenticated endpoint, `/api/plugins/validate`, instead of the admin-only route.
+2. Updated the browser validation helper to treat non-`2xx` validation responses as real validation failures instead of silently proceeding.
+3. Added shared plugin-validation defaults for built-in/internal action types, including SimpleChat and internal document search.
+4. Applied those defaults before server-side manifest health checks so validation and save use the same rules.
+5. Added backend regression coverage for SimpleChat validation without a user-entered endpoint.
+6. Extended the workspace SimpleChat modal UI test to cover validation plus save and verify the admin validation route is not used.
+
+## Validation
+
+- Functional test: `functional_tests/test_plugin_validation_managed_fields_compatibility.py`
+- UI test: `ui_tests/test_workspace_simplechat_action_modal.py`
+
+## Impact
+
+- Workspace users can now validate and save SimpleChat actions without needing admin permissions.
+- Built-in internal actions no longer fail validation just because they do not expose a user-editable endpoint field.
+- Shared validation now fails loudly and correctly when the validation endpoint itself rejects a request.

+# SimpleChat Admin Action Save Fix
+
+Fixed/Implemented in version: **0.241.065**
+
+## Overview
+
+Saving the built-in SimpleChat action from Global Actions could fail in two places: the summary step in the admin modal threw a browser-side `ReferenceError`, and the admin save route could still reject the manifest for a missing `endpoint` even though SimpleChat is an internal built-in action.
+
+## Root Cause
+
+- `plugin_modal_stepper.js` used `isSimpleChatType` inside `getAuthTypeValue()` without defining the local variable first, which broke Step 5 before the form could finish rendering the summary.
+- The admin add/edit routes validated the raw manifest with the plugin health checker after only partially applying runtime defaults.
+- For built-in action types like SimpleChat, the incoming payload can legitimately include `endpoint: ""`, and `setdefault(...)` does not replace an already-present blank string.
+
+## Files Modified
+
+- `application/single_app/static/js/plugin_modal_stepper.js`
+- `application/single_app/route_backend_plugins.py`
+- `application/single_app/config.py`
+- `functional_tests/test_simplechat_admin_action_save_fix.py`
+
+## Code Changes Summary
+
+1. Defined the missing `isSimpleChatType` local in the summary auth-type helper so Step 5 can render for SimpleChat actions.
+2. Updated built-in action runtime defaults to replace blank endpoints, not just absent ones.
+3. Applied `apply_plugin_validation_defaults(...)` inside the admin add/edit routes before running manifest health validation so the health checker sees the same normalized manifest as the shared validation endpoint.
+4. Added a focused regression covering the summary-step contract and the admin save normalization path.
+
+## Validation
+
+- Functional test: `functional_tests/test_simplechat_admin_action_save_fix.py`
+
+## Impact
+
+- Global Actions can now render the SimpleChat summary step without a browser-side exception.
+- Admin saves no longer reject SimpleChat just because the modal sends an empty `endpoint` field for a built-in action.

+# SimpleChat Background Tasks Deployment Fix
+
+Fixed in version: **0.241.057**
+
+Deployer version: **1.0.2**
+
+## Issue Description
+
+Deployed containers could start with `SIMPLECHAT_RUN_BACKGROUND_TASKS` disabled, which prevented the in-app scheduler loops from running after startup. Long-running tabular generated-output jobs could still begin from the original request executor, but queued retry runs were not automatically picked up later.
+
+## Root Cause Analysis
+
+The application supports `SIMPLECHAT_RUN_BACKGROUND_TASKS` as an environment switch, but the deployer did not explicitly set it in App Service app settings. When the deployment environment carried the value as disabled, every web-process initialization logged `Background tasks disabled for this web process`, leaving queued retry jobs dependent on manual recovery.
+
+## Version Implemented
+
+Fixed in application version: **0.241.057**
+
+Fixed in deployer version: **1.0.2**
+
+## Technical Details
+
+### Files Modified
+
+- `deployers/bicep/modules/appService.bicep`
+- `deployers/bicep/main.json`
+- `deployers/azure.yaml`
+- `deployers/azurecli/deploy-simplechat.ps1`
+- `deployers/version.txt`
+- `functional_tests/test_deployer_background_tasks_app_setting.py`
+
+### Code Changes Summary
+
+- Added `SIMPLECHAT_RUN_BACKGROUND_TASKS=1` to the Bicep App Service app settings used by `azd provision` and `azd up`.
+- Added the same setting to the shipped ARM template used by one-click deploy.
+- Added an `azd deploy` predeploy guard that sets `SIMPLECHAT_RUN_BACKGROUND_TASKS=1` before restarting the web app, covering image-only redeploys.
+- Added the same setting to the legacy Azure CLI deployment script.
+- Bumped `deployers/version.txt` from `1.0.1` to `1.0.2`.
+
+### Testing Approach
+
+- Added a functional source-level regression that verifies all deployment paths configure the background task setting.
+- Compiled the new functional test.
+
+## Impact Analysis
+
+Fresh `azd up` deployments and subsequent `azd deploy` runs now explicitly enable SimpleChat background scheduler loops in the App Service container. This allows queued retry jobs, stale run cleanup, workflow scheduling, file sync scheduling, and similar app-managed loops to run after deployment.
+
+## Validation
+
+### Before
+
+- App Service could retain or receive `SIMPLECHAT_RUN_BACKGROUND_TASKS=0` or `false`.
+- Logs showed `Background tasks disabled for this web process`.
+- Queued tabular retry runs were not automatically resumed.
+
+### After
+
+- App Service app settings include `SIMPLECHAT_RUN_BACKGROUND_TASKS=1`.
+- `azd deploy` reinforces the setting even when infrastructure is not reprovisioned.
+- The container starts the in-app background task loops unless explicitly changed after deployment.
+
+## Related Version Updates
+
+- `deployers/version.txt` was updated to **1.0.2**.

+- Code changes summary: Restored `create_group_for_current_user(...)`, preserved its feature-gating and notification flow, and added a focused regression test that compiles the wrapper in isolation and verifies its call sequence and normalization behavior.
+- Testing approach: Added a functional regression test for the wrapper export and behavior, then validated the source surface with a dependency-free AST check because full app import in this environment is blocked by local Cosmos credential configuration.
+
+## Validation
+
+- Test results: The new regression test verifies the wrapper exists, normalizes blank group names to `Untitled Group`, trims descriptions, and still notifies after group creation.
+- Before/after comparison: Before the fix, importing the group route failed immediately with `ImportError: cannot import name 'create_group_for_current_user'`. After the fix, the expected wrapper symbol is present again for both route and plugin callers.
+- User experience improvements: The app can proceed past this startup regression instead of crashing during module import.

+
+# SimpleChat Group Multi-User Conversation Guidance Fix
+
+Fixed/Implemented in version: **0.241.031**
+
+> Note: This guidance was later superseded by invite-managed group multi-user conversations in version **0.241.034**. Group members now need to be added as conversation participants instead of inheriting access automatically through group membership.
+
+## Issue Description
+
+SimpleChat already supported creating a group collaborative conversation, but the capability text was vague enough that an agent could interpret it as a one-off group chat that still needed separate participant invites. In incident-style workflows this led to incomplete execution summaries such as creating the group and adding users, but reporting that the group conversation tool was unavailable or insufficient.
+
+Related config update: `application/single_app/config.py` now sets `VERSION = "0.241.031"`.
+
+## Root Cause Analysis
+
+- The existing capability label used the generic phrase `Create Group Conversations`.
+- The existing tool description did not make it clear that this is the group multi-user conversation path.
+- The existing result payload did not explicitly tell the agent that current and future group members inherit access through group membership without separate conversation invites.
+
+## Technical Details
+
+Files modified:
+
+- `application/single_app/functions_simplechat_operations.py`
+- `application/single_app/semantic_kernel_plugins/simplechat_plugin.py`

+- `ui_tests/test_agent_modal_simplechat_capabilities.py`
+- `ui_tests/test_workspace_simplechat_action_modal.py`
+
+Code changes summary:
+
+- Renamed the user-facing capability label to `Create Group Multi-User Conversations`.
+- Updated backend and plugin descriptions to state that the conversation is tied to group membership.
+- Added an explicit plugin return message for the original group-membership model. That guidance is now superseded by the invite-managed participant flow introduced in `0.241.034`.
+- Added a focused functional regression to lock the new guidance in place.
+
+Testing approach:
+
+- Functional test for metadata and result messaging.
+- Existing SimpleChat capability and UI regressions updated to reflect the clarified label.
+
+## Validation
+
+Before:
+
+- The agent could treat group conversation creation as ambiguous and report the tool as effectively unavailable for a multi-user incident flow.
+
+After:
+
+- The tool surface now clearly advertises that it creates the group multi-user conversation for the group itself.
+- The return payload reinforces that added users do not need separate conversation invites.

+# Source Review Deep Traversal Fix
+
+Fixed in version: **0.241.042**
+
+Further refined in version: **0.241.044**
+
+Further refined in version: **0.241.045**
+
+Further refined in version: **0.241.046**
+
+## Issue Description
+
+Source Review improved answers by reviewing source pages, but Deep Source Review could over-invest remaining page budget in child links from the first reviewed source page. For multi-source research requests, that meant one official archive could contribute several child pages while another archive received less follow-up exploration.
+
+## Root Cause Analysis
+
+The initial traversal queue allowed child links to be queued while seed source pages were still waiting. This made child selection depend too heavily on seed order instead of first reviewing all initial source/archive pages and then spending leftover budget on the best child links across those pages.
+
+## Technical Details
+
+### Files Modified
+
+* `application/single_app/functions_source_review.py`
+* `application/single_app/config.py`
+* `functional_tests/test_source_review_deep_traversal.py`
+* `functional_tests/test_source_review_security.py`
+* `docs/explanation/features/v0.241.041/SOURCE_REVIEW.md`
+
+### Code Changes Summary
+
+* Source Review now reviews all seed URLs within the page budget before pulling child-link candidates into the active fetch queue.
+* Deep traversal now ranks child candidates across seed pages, so later seed pages can still contribute the best follow-up links.
+* Archive-style requests now favor generic release/detail link patterns and penalize common non-evidence navigation paths such as about, careers, awards, privacy, and annual report pages.
+* The v0.241.044 refinement scores extracted links before enforcing the per-page link inventory limit, so press-release/detail links are not dropped just because a page emits navigation links first.
+* The v0.241.045 refinement passes all Foundry web-search URL citations into Source Review, adds a seed-page budget, and allows bounded second-hop traversal for official archive -> section/year -> detail-page flows.
+* The v0.241.046 refinement adds bounded Load More handling to the optional rendered-page path so interactive official archives can expose more dated source links before evidence extraction.
+* Source Review audit logs now include Deep Source Review usage, seed and child page counts, planner attempted/used state, planner candidate count, and selected planner URLs for easier diagnosis.
+* Malformed link entries are ignored defensively, and unexpected fetch/extraction failures now include traceback logging for diagnosis.
+* App version was updated in `application/single_app/config.py` to `0.241.042`.
+* App version was updated in `application/single_app/config.py` to `0.241.044` for the link-prioritization and audit refinement.
+* App version was updated in `application/single_app/config.py` to `0.241.045` for the citation seeding and second-hop traversal refinement.
+* App version was updated in `application/single_app/config.py` to `0.241.046` for the rendered Load More refinement.
+
+### Testing Approach
+
+* Added `functional_tests/test_source_review_deep_traversal.py` to validate source-archive child-link prioritization and cross-seed child selection without company-specific rules.
+* Added v0.241.044 regression coverage for relevant links surviving noisy navigation and for generic same-domain navigation being rejected for archive-style requests.
+* Added v0.241.045 regression coverage for raw Foundry citations becoming Source Review seeds and for bounded second-hop traversal with reserved seed budget.
+* Added v0.241.046 regression coverage for Load More control detection and click-cap clamping.
+* Updated `functional_tests/test_source_review_security.py` to the current config version.
+
+## Validation
+
+The targeted Source Review tests validate that Deep Source Review can identify a relevant release/detail page over generic navigation links and choose high-value child links from later seed archives.
+
+## Impact Analysis
+
+Multi-source web research should now make better use of Deep Source Review. The behavior remains bounded by the configured page budget, hard safety ceilings, SSRF controls, and prompt-injection isolation.

+# Source Review Depth Save Fix
+
+Fixed/Implemented in version: **0.241.078**
+
+## Issue Description
+
+Admins could enter `2` for Deep Research Source Traversal Depth, and the save action appeared successful, but the page showed the value as `1` again after reload.
+
+## Root Cause Analysis
+
+The Admin Settings form contained an accidental duplicate `source_review_max_depth` input inside the User-Facing Latest Features visibility section. That earlier field was posted before the real Deep Research Source Traversal Depth field, so the backend read the stale first value from the form data.
+
+## Version Implemented
+
+- Application version updated in `application/single_app/config.py` to `0.241.078`.
+
+## Technical Details
+
+### Files Modified
+
+- `application/single_app/templates/admin_settings.html`
+- `application/single_app/config.py`
+- `functional_tests/test_admin_source_review_depth_save.py`
+
+### Code Changes Summary
+
+- Restored the Latest Features visibility control to the intended `support_latest_feature_{{ feature.id }}` checkbox.
+- Removed the duplicate `source_review_max_depth` form field outside the Deep Research settings card.
+- Added a regression test to ensure the Admin Settings form contains only one `source_review_max_depth` field.
+
+### Testing Approach
+
+- Static functional test verifies the Source Traversal Depth field name appears exactly once.
+- Static functional test verifies the Latest Features section posts feature visibility checkbox names instead of Deep Research settings.
+
+## Impact Analysis
+
+Saving Source Traversal Depth now persists the intended value from the Deep Research settings card. Latest Features visibility checkboxes also render with the expected field names again.

+# Source Review Dynamic Grid Archive Fix
+
+Fixed in version: **0.241.065**
+
+## Issue Description
+
+Source Review could review dynamic archive pages such as `https://www.jpmorganchase.com/ir/news`, but the static HTML extraction saw only the shell/navigation content. In the JPMorgan case this produced only a couple of structured items even though the rendered archive exposes many dated press-release rows and a Load More control.
+
+The same run also showed a skipped source with a `NoneType` date-extraction error, allowing one malformed archive candidate to skip an otherwise usable page.
+
+## Root Cause Analysis
+
+Some AEM dynamic-grid archive pages publish their repeated card rows through a same-origin JSON service advertised by `data-dg-action` attributes. Source Review detected the Load More control but did not consume the JSON endpoint when JavaScript rendering was disabled, so it undercounted client-rendered archives.
+
+Date extraction also assumed every structured candidate had a BeautifulSoup-like container, which was not true for all archive/link candidates.
+
+## Technical Details
+
+### Files Modified
+
+- `application/single_app/functions_source_review.py`
+- `functional_tests/test_source_review_security.py`
+- `functional_tests/test_document_analysis_lossless_artifacts.py`
+- `application/single_app/config.py`
+
+### Code Changes Summary
+
+- Added generic AEM dynamic-grid detection for HTML pages with `data-dg-action` metadata.
+- Fetches the advertised same-origin JSON endpoint with existing Source Review URL validation before any request.
+- Converts dynamic-grid JSON rows into Source Review `structured_items` with normalized title, URL, date, nearby text, score, and source type.
+- Merges dynamic-grid rows into the existing link inventory so Deep Source Review can follow those dated release URLs.
+- Added guards so missing date containers return an empty date instead of failing the whole page.
+- Updated the application version in `config.py` to `0.241.065`.
+
+### Testing Approach
+
+- Added a Source Review functional regression using a fake dynamic-grid JSON endpoint to verify dated client-rendered archive rows are folded into `structured_items`.
+- Added a regression for missing date containers.
+- Re-ran Source Review extraction/security tests.
+
+## Validation
+
+### Test Results
+
+- `python -m py_compile application/single_app/functions_source_review.py functional_tests/test_source_review_security.py`
+- `python functional_tests/test_source_review_security.py` -> 11/11 tests passed
+
+### Before
+
+Source Review on JPMorgan's IR news archive saw the page title/navigation and detected Load More, but extracted only a very small number of non-release structured items when JavaScript rendering was unavailable or disabled.
+
+### After
+
+Source Review can use the page's own dynamic-grid JSON service to extract the archive rows directly, including dated press-release titles and links. This gives Deep Research enough structured evidence to answer from the official JPMorgan archive instead of relying primarily on third-party search results.

+# SQL Container ODBC Runtime Fix (v0.241.064)
+
+Fixed/Implemented in version: **0.241.064**
+
+## Issue Summary
+
+Fresh container deployments failed the SQL Server "Test Connection" flow with `Database driver not installed: libodbc.so.2: cannot open shared object file: No such file or directory`.
+
+## Root Cause
+
+- The application Docker build installed `pyodbc`, but the final distroless runtime image did not carry forward the unixODBC shared libraries required at runtime.
+- Azure Linux 3 publishes `msodbcsql18` in the supported Microsoft non-OSS package feed, while the app still defaulted new SQL configurations and examples to ODBC Driver 17.
+- That mismatch meant fresh container deployments could fail before connecting, and new SQL configurations would still point at an older driver that is not present in the image.
+
+## Files Modified
+
+- `application/single_app/Dockerfile`
+- `application/single_app/config.py`
+- `application/single_app/route_backend_plugins.py`
+- `application/single_app/semantic_kernel_plugins/sql_query_plugin.py`

+- `application/single_app/templates/_plugin_modal.html`
+- `functional_tests/test_sql_container_odbc_runtime.py`
+
+## Code Changes Summary
+
+1. Added the Azure Linux Microsoft non-OSS repository to the builder image and installed `unixODBC`, `unixODBC-devel`, and `msodbcsql18`.
+2. Packaged the required ODBC runtime files into an intermediate `/odbc-runtime` directory and copied them into the final distroless image, including `odbcinst.ini`, unixODBC shared libraries, and the Microsoft SQL driver files under `/opt/microsoft`.
+3. Switched fresh SQL Server defaults, factory-generated connection strings, UI defaults, and documentation examples from ODBC Driver 17 to ODBC Driver 18.
+4. Improved the SQL test-connection error for missing unixODBC runtime and for explicit Driver 17 selection in the container image.
+5. Added a focused regression test that validates the container packaging and fresh-driver defaults.
+
+## Validation
+
+- `functional_tests/test_sql_container_odbc_runtime.py` checks that the Dockerfile now packages the unixODBC runtime and `msodbcsql18` artifacts for the distroless image.
+- The same functional test validates that backend defaults, frontend defaults, and SQL examples all point to ODBC Driver 18 for fresh deployments.
+- The SQL driver picker regression check keeps ODBC Driver 17 available for older custom images, but prioritizes ODBC Driver 18 for the supported container path.
+
+## Impact
+
+- Fresh container deployments can load `pyodbc` successfully for SQL Server connectivity.
+- New SQL plugin configurations now default to the driver version that the Azure Linux container image actually ships.
+- Existing custom environments can still choose ODBC Driver 17 explicitly if they build images that provide it.

+# TABULAR ANALYSIS HEARTBEAT FIX
+
+Fixed in version: **0.241.136**
+
+## Overview
+
+Long-running tabular requests could appear complete too early in the chat progress card even though backend analysis was still active. Users saw a `100%` tabular card and "Workbook evidence ready" while the Semantic Kernel tabular loop continued retrying or preparing the final response.
+
+## Root Cause
+
+- The tabular progress card treated "no currently running activities" as completion.
+- The tabular retry loop logged retry reasons to the backend but did not emit a user-visible lifecycle heartbeat between attempts.
+- As a result, completed tool calls could temporarily leave the UI with no running activity, causing a false completed state.
+
+## Technical Details
+
+### Files Modified
+
+- `application/single_app/route_backend_chats.py`
+- `application/single_app/static/js/chat/chat-thoughts.js`
+- `functional_tests/test_workspace_tabular_trigger_and_thoughts.py`
+- `ui_tests/test_chat_tabular_thought_progress.py`
+
+### Code Changes Summary
+
+- Added a stable tabular lifecycle activity payload for long-running analysis and retry heartbeats.
+- Emitted lifecycle thoughts when tabular analysis starts, retries, and hands off to final response synthesis.
+- Threaded the lifecycle callback through `run_tabular_analysis_with_multi_file_support(...)` and `run_tabular_sk_analysis(...)`.
+- Changed the chat progress renderer so tool-only tabular activity no longer auto-completes just because no tool is currently running.
+- Kept export-specific wording reserved for actual tabular post-processing/export phases.
+
+## Testing
+
+- Functional regression updated in `functional_tests/test_workspace_tabular_trigger_and_thoughts.py`
+- UI regression updated in `ui_tests/test_chat_tabular_thought_progress.py`
+- Python syntax validation via `py_compile`
+- JavaScript syntax validation via `node --check`
+
+## Validation
+
+### Result
+
+- Tool-only tabular analysis now stays visibly active after workbook tool calls finish and before the final response arrives.
+- Retry passes now surface a visible heartbeat such as "Retrying workbook analysis (attempt X of 3)".
+- The progress card no longer shows export wording for normal tabular retry/lifecycle activity.
+
+### User Impact
+
+- Users can distinguish between true completion and ongoing backend analysis.
+- Long-running workbook analysis now remains visibly active instead of looking hung or falsely complete.
+- Final completion is tied to real terminal phases such as export completion or final model response.

+# Tabular Analysis Progress Fix
+
+Fixed in version: **0.241.133**
+
+## Issue Description
+
+Tabular analysis requests in chat could sit on the initial `Starting tabular analysis across N file(s)` thought for the full duration of the workbook processing run. The analysis still completed, but the user did not get the expected live progress card or a clear completion state while the tabular tools were running.
+
+## Root Cause Analysis
+
+- `register_tabular_invocation_thought_callback()` in `route_backend_chats.py` registered tabular callbacks under a tabular-specific key.
+- `PluginInvocationLogger` dispatches start and completion callbacks using the shared `user_id:conversation_id` key.
+- Because the keys did not match, live tabular tool start/completion events were never delivered to the thought renderer, so the chat UI stayed on the generic start thought instead of switching to the existing tabular progress card.
+
+## Version Implemented
+
+- **0.241.133**
+
+## Files Modified
+
+- `application/single_app/route_backend_chats.py`
+- `application/single_app/config.py`
+- `functional_tests/test_workspace_tabular_trigger_and_thoughts.py`
+- `ui_tests/test_chat_tabular_thought_progress.py`
+
+## Code Changes Summary
+
+- Aligned the tabular live thought callback registration key with the shared plugin logger dispatch contract.
+- Added a focused backend regression that verifies the tabular callback key and confirms running/completed activity thoughts are emitted through the shared logger path.
+- Added a UI regression that simulates live tabular thought updates and verifies the progress card advances from a running state to a completed state.
+- Updated the application version and the touched test file headers to the release that contains the fix.
+
+## Testing Approach
+
+- Ran `python -m py_compile application/single_app/route_backend_chats.py`.
+- Ran `functional_tests/test_workspace_tabular_trigger_and_thoughts.py`.
+- Ran `python -m py_compile ui_tests/test_chat_tabular_thought_progress.py`.
+- Ran `pytest ui_tests/test_chat_tabular_thought_progress.py -q`.
+
+## Impact Analysis
+
+- Long-running tabular analysis now surfaces the same progress-card experience the chat UI already supports for live activity updates.
+- Users can see that tabular tool work is active instead of waiting on a static start badge.
+- The completion state is now visible from live tabular thought updates before the final response fully takes over the message area.
+
+## Validation
+
+- Before: the chat UI could remain on the generic start thought for the entire tabular run even though tool invocations were being logged.
+- After: live tabular tool updates flow through the shared callback path, the progress card appears while work is running, and the final tool update drives the card to a completed state.

+# Tabular Background Export Queued Retry Resume Fix
+
+Fixed in version: **0.241.057**
+
+## Issue Description
+
+Checkpointed tabular generated-output exports could remain in `queued` after a transient retry window passed when the deployment had web-process background tasks disabled. The progress card showed the saved checkpoint counts and transient retry count, but did not expose Continue after `next_attempt_at` was in the past.
+
+## Root Cause Analysis
+
+The original chat request submitted the export to the Flask executor, so the first processing attempt could run even when scheduler loops were disabled. After an `APIConnectionError`, the runner correctly requeued the run with `next_attempt_at`, but no scheduler was active to pick it up later. Public status only treated queued runs as manually resumable while they were still waiting for a future retry, so once the retry time passed the UI returned to plain Queued with no recovery action.
+
+## Version Implemented
+
+Fixed in version: **0.241.057**
+
+## Technical Details
+
+### Files Modified
+
+- `application/single_app/functions_tabular_generated_exports.py`
+- `application/single_app/config.py`
+- `functional_tests/test_tabular_background_generated_exports.py`
+- `docs/explanation/features/TABULAR_BACKGROUND_GENERATED_EXPORTS.md`
+
+### Code Changes Summary
+
+- Added queued retry-due detection so a retryable queued run becomes manually resumable after `next_attempt_at` has passed.
+- Added stale queued-run detection so a queued run that sits longer than the configured stale threshold can be resubmitted from checkpoints.
+- Added a `retry_due` public status field and clearer Needs Attention status details for overdue queued retries.
+- Increased the default scheduler scan limit from 1 to 5 to reduce candidate starvation.
+- Added debug-only scheduler scan result logging with processed and skipped candidates.
+
+### Testing Approach
+
+- Updated the durable export functional regression to assert queued retry recovery, stale queued recovery, scheduler scan diagnostics, and the new version header.
+- Compiled the modified Python files.
+
+## Impact Analysis
+
+Users can now kick a checkpointed queued retry forward from the progress card even when the automatic scheduler is not running in the web process. The scheduler also has better scan breadth and logging when it is enabled, making future production investigations clearer.
+
+## Validation
+
+### Before
+
+- A run requeued after a transient connection error could sit as Queued after the retry time passed.
+- The progress card showed Refresh Status but no Continue button.
+- Logs did not show scheduler candidate decisions when no run was processed.
+
+### After
+
+- Overdue queued retries return `can_resume: true` and `status_label: Needs Attention`.
+- Stale queued runs can be continued from completed checkpoints.
+- Scheduler scans record candidate, processed, and skipped counts in debug logs.
+
+## Related Version Updates
+
+- `application/single_app/config.py` was updated to version **0.241.057**.

+# Tabular Background Export Scheduler and Worker Recycle Fix
+
+Fixed in version: **0.241.058**
+
+## Issue Description
+
+Large checkpointed tabular generated-output exports could require manual Continue clicks after transient connection failures. Production logs showed the automatic scheduler running, but every scheduler scan failed with a Cosmos DB `BadRequest` before it could pick up queued retry runs. The same log window also showed Gunicorn request-count worker recycling while long exports were active.
+
+## Root Cause Analysis
+
+The scheduler used one broad cross-partition Cosmos SQL query with mixed status predicates, string `CONTAINS` checks, date comparisons, and `ORDER BY`. In production this query failed with `One of the input values is invalid`, so queued retry runs were never automatically claimed. Manual Continue worked because it bypassed that scheduler query and submitted the run directly to the Flask executor.
+
+At the same time, the default Gunicorn `max_requests` recycle could terminate web workers that were hosting long in-process background export work, causing the export to requeue after transient connection errors.

+- `functional_tests/test_tabular_background_generated_exports.py`
+
+### Code Changes Summary
+
+- Replaced the broad scheduler Cosmos query with simple status-specific queries and Python-side due filtering for queued, running, and failed runs.
+- Removed scheduler dependence on Cosmos string `CONTAINS`, date comparisons, and `ORDER BY` for retry discovery.
+- Added scheduler diagnostics for scanned counts by status and candidate decisions.
+- Cleared `next_attempt_at` when a run is claimed and added active-processing-time ETA tracking so paused wall-clock time does not inflate remaining time estimates.
+- Made Gunicorn disable request-count recycling by default when `SIMPLECHAT_RUN_BACKGROUND_TASKS` is enabled, with a longer graceful timeout for background-capable workers.
+
+## Testing Approach
+
+- Updated the durable export functional regression to assert the scheduler query shape, Python-side candidate filtering, active-time ETA accounting, and Gunicorn background-task-aware recycle defaults.
+- Compiled the modified Python files.
+
+## Impact Analysis
+
+Automatic retries can resume checkpointed generated-output exports without manual hand-holding after transient failures. Long in-process exports are less likely to be interrupted by routine Gunicorn request-count recycling while still preserving explicit environment overrides for deployments that want different worker behavior.
+
+## Validation
+
+### Before
+
+- Scheduler scans repeatedly failed with Cosmos DB `BadRequest`.
+- Queued retry runs needed manual Continue to make progress.
+- Gunicorn request-count recycling could stop a worker while a long background export was active.
+- Estimated remaining time included paused time between attempts.
+
+### After
+
+- Scheduler scans use simpler Cosmos queries and filter retry/stale logic in Python.
+- Retryable queued and failed runs can be claimed automatically from checkpoints.
+- Background-capable Gunicorn workers do not recycle by request count unless explicitly configured.
+- Remaining-time estimates are based on active batch processing time.
+
+## Related Version Updates
+
+- `application/single_app/config.py` was updated to version **0.241.058**.

+# Tabular Background Export Transient Resume Fix
+
+Fixed in version: **0.241.048**
+
+## Issue Description
+
+Durable tabular generated-output runs could still become failed when the background worker hit a transient Azure OpenAI connection interruption during a long export. A production run for `cftc-comments.xlsx` reached batch 183 of 1,592 and then failed after Gunicorn began recycling the worker process.
+
+## Root Cause Analysis
+
+The export was properly checkpointing completed batches, but the runner treated any exception from Semantic Kernel or Azure OpenAI as terminal. During worker recycle, the in-process background thread received an `APIConnectionError('Connection error.')`; the run was marked `failed` even though the completed batch blobs were durable and the next scheduler pass could safely resume.
+
+## Version Implemented
+
+Fixed in version: **0.241.048**
+
+## Technical Details
+
+### Files Modified
+
+- `application/single_app/functions_tabular_generated_exports.py`
+- `application/single_app/config.py`
+- `functional_tests/test_tabular_background_generated_exports.py`
+
+### Code Changes Summary
+
+- Added retryable error classification for OpenAI/Semantic Kernel connection, timeout, rate-limit, and transient service errors.
+- Requeue retryable failures with bounded backoff instead of marking them terminal.
+- Let the scheduler reclaim retryable failed runs based on their persisted `last_error` so already-failed checkpointed runs can resume.
+- Preserve hard validation failures as terminal failures.
+
+### Testing Approach
+
+- Updated the durable export functional regression to assert transient resume markers are present.
+- Compiled the modified Python files.
+
+## Impact Analysis
+
+Long-running generated exports can now survive transient model-service interruptions and Gunicorn worker recycling. The next scheduler pass resumes from completed output checkpoints instead of restarting from the beginning or leaving the run failed.
+
+## Validation
+
+### Before
+
+- `APIConnectionError('Connection error.')` during a background batch marked the entire run `failed`.
+- The progress card stopped at the last completed checkpoint.
+
+### After
+
+- Retryable connection failures move the run back to `queued` with a short backoff.
+- Retryable failed runs are eligible for scheduler pickup.
+- Completed batches remain preserved and the next attempt resumes at the next batch.
+
+## Related Version Updates
+
+- `application/single_app/config.py` was updated to version **0.241.048**.

+# Tabular Document Action Live Activity Fix - v0.241.038
+
+Fixed in version: **0.241.038**
+
+## Issue Description
+
+Chat document-action runs for selected tabular documents could remain visually stuck on the initial queued message, such as `Queued analyze for 1 selected document`, even while the backend was actively running workbook analysis. Logs showed `TabularProcessingPlugin` calls completing successfully, but the chat UI did not transition into the live tabular analysis activity card.
+
+## Root Cause Analysis
+
+- The chat route created a `ThoughtTracker` and live document-action stream callback before dispatching document actions.
+- The workflow runner's tabular document-action helper invoked `run_tabular_analysis_with_thought_tracking(...)` without passing either object.
+- Because the tabular helper did not receive the tracker or live callback, lifecycle events, tabular tool start/completion activity, and generated-output post-processing thoughts were not persisted or streamed for document-action tabular runs.
+
+## Technical Details
+
+### Files Modified
+
+- `application/single_app/functions_workflow_runner.py`
+- `application/single_app/config.py`
+- `functional_tests/test_tabular_document_actions_workflow.py`
+- `docs/explanation/fixes/TABULAR_DOCUMENT_ACTION_LIVE_ACTIVITY_FIX.md`
+
+### Code Changes Summary
+
+- Added a document-action tabular thought callback bridge that can persist tabular post-processing thoughts and forward them to the existing live stream callback.
+- Passed `thought_tracker` and `live_thought_callback` into `run_tabular_analysis_with_thought_tracking(...)` for Analyze and comparison document actions.
+- Wired generated tabular output post-processing to publish progress thoughts during export preparation and upload.
+- Incremented `config.py` from `0.241.037` to `0.241.038`.
+
+## Validation
+
+### Test Results
+
+- `functional_tests/test_tabular_document_actions_workflow.py` verifies the tabular document-action helper accepts and forwards live thought tracking, and that Analyze/comparison model and agent paths pass the stream callback.
+
+### User Experience Improvements
+
+- Selected workbook analysis now transitions from the queued document-action message into the live tabular analysis activity card.
+- Users can see workbook evidence gathering, tool calls, retries, and export post-processing instead of interpreting a quiet UI as a hung run.

+# TABULAR DOCUMENT ACTION LIVE PROGRESS FIX
+
+Fixed in version: **0.241.138**
+
+## Issue Description
+
+Tabular document actions launched from chat Analyze and compare could sit on the initial queued badge for the full duration of the workbook run. The backend was still doing work, but the user did not see the existing tabular lifecycle or tool-progress thoughts, which made the request look stuck.
+
+## Root Cause Analysis
+
+- The shared `_maybe_execute_tabular_document_action(...)` helper in `functions_workflow_runner.py` called `run_tabular_analysis_with_thought_tracking(...)` without the active `thought_tracker`.
+- The same helper also dropped the live stream callback, so streamed chat requests never received tabular lifecycle or tool updates after the initial queued message.
+- The document-action stream callback in `route_backend_chats.py` only translated legacy analysis/comparison activity events and did not forward preformatted tabular thought payloads.
+
+## Version Implemented
+
+- **0.241.138**
+
+## Files Modified
+
+- `application/single_app/route_backend_chats.py`
+- `application/single_app/functions_workflow_runner.py`
+- `application/single_app/config.py`
+- `functional_tests/test_tabular_document_actions_workflow.py`
+
+## Code Changes Summary
+
+- Added passthrough support for preformatted streamed thought payloads in the document-action chat callback.
+- Threaded the active `thought_tracker` and live stream callback through the shared tabular document-action helper.
+- Updated the document analysis and comparison workflow branches so tabular workbook analysis emits the same live progress thoughts as the main chat tabular path.
+- Added a focused regression test that verifies the live-thought plumbing remains in place.
+
+## Testing Approach
+
+- Ran `pytest functional_tests/test_tabular_document_actions_workflow.py`
+- Planned narrow Python syntax validation on the touched backend files
+
+## Impact Analysis
+
+- Long-running tabular Analyze and compare requests now show ongoing lifecycle and tool activity instead of a static queued badge.
+- Users can tell the request is still active while workbook evidence is being gathered.
+- The fix only changes progress/thought plumbing for tabular document actions; the underlying analysis and comparison logic is unchanged.
+
+## Validation
+
+- Before: tabular document actions could remain on `Queued analysis...` or `Queued comparison...` with no visible progress during workbook analysis.
+- After: tabular lifecycle and tool thoughts stream through the existing chat progress renderer, so users see active progress until the final response is ready.

+# TABULAR DOCUMENT ACTION STRUCTURED EXPORT FIX
+
+Fixed in version: **0.241.139**
+
+## Issue Description
+
+Tabular document Analyze and compare requests could use workbook analysis internally but still return only a short synthesized answer, even when the prompt explicitly asked for exhaustive row-level JSON or CSV output. In large classification runs, users could see thousands of matched rows in tool results but only a handful of final objects in the response.
+
+## Root Cause Analysis
+
+- The shared tabular document-action helper in `functions_workflow_runner.py` stopped after collecting workbook analysis text and never reused the chat tabular generated-output pipeline.
+- That helper also skipped row-linked related-document augmentation, so references resolved from workbook rows were not carried into structured export generation or synthesis prompts.
+- As a result, tabular analysis/compare behaved like a summary shortcut instead of reusing the more exhaustive tabular export path already available in the main chat/search flow.
+
+## Version Implemented
+
+- **0.241.139**
+
+## Files Modified
+
+- `application/single_app/functions_workflow_runner.py`
+- `application/single_app/config.py`
+- `functional_tests/test_tabular_document_actions_workflow.py`
+
+## Code Changes Summary
+
+- Reused `augment_tabular_invocations_with_related_document_evidence(...)` inside the shared tabular document-action helper.
+- Reused `maybe_create_tabular_generated_output(...)` so analysis/compare can attach exhaustive row-level JSON or CSV exports when the prompt asks for them.
+- Passed related-document evidence summaries into the computed-results prompt handoff for analysis and comparison synthesis.
+- Updated synthesis prompts so the assistant summarizes key findings and points users to attached exports instead of implying the full dataset is inline.
+
+## Testing Approach
+
+- Ran `pytest functional_tests/test_tabular_document_actions_workflow.py`
+- Planned narrow Python syntax validation on `functions_workflow_runner.py` and the updated regression file
+
+## Impact Analysis
+
+- Tabular document Analyze and compare now behave much closer to the main chat/search tabular flow for exhaustive structured-output requests.
+- Large per-row classification prompts can now attach downloadable exhaustive exports instead of collapsing everything into one short synthesized answer.
+- Row-linked external-document evidence is now available to both export generation and the final synthesis prompt when the workbook rows reference supporting documents.
+
+## Validation
+
+- Before: the workflow could find the full matching workbook rows but still produce only a small synthesized response with no reusable structured export.
+- After: the same workflow can prepare exhaustive tabular exports, preserve related-document evidence, and return a concise summary that points to the attached full result set.

+# Tabular Generated Export Artifact Presentation Fix
+
+Fixed in version: **0.241.064**
+
+## Issue Description
+
+Large workflow/document-analysis requests that produced a full generated JSON or CSV export could also attach secondary analysis JSON and Markdown artifacts. The result was noisy: the useful CSV preview, the analysis JSON artifact, the Markdown artifact, and the full generated export card all appeared together, making it unclear which file was the real deliverable.
+
+## Root Cause
+
+The document-analysis artifact builder treated exhaustive analysis outputs as standalone deliverables even when the tabular generated-output pipeline had already queued or attached the full row-level export. That caused the reduced analysis reply to be saved as additional JSON/Markdown artifacts beside the actual generated export.
+
+## Technical Details
+
+Files modified:
+
+- `application/single_app/functions_workflow_runner.py`
+- `functional_tests/test_document_analysis_lossless_artifacts.py`
+- `docs/explanation/features/TABULAR_BACKGROUND_GENERATED_EXPORTS.md`
+- `application/single_app/config.py`
+
+Code changes summary:
+
+- Added primary generated tabular output awareness to document-analysis artifact creation.
+- Kept the supporting CSV analysis preview when available.
+- Suppressed redundant analysis JSON artifacts when a full generated tabular export exists.
+- Suppressed Markdown/raw-note analysis artifacts unless the user explicitly requested Markdown.
+- Updated generated analysis artifact filenames to strip source extensions and avoid `*-analysis.json-analysis.md` style names.
+
+Testing approach:
+
+- Added a functional regression covering the primary generated JSON export plus supporting CSV preview presentation.
+- Verified the assistant reply no longer inlines a duplicate preview or promotes secondary Markdown/raw-note artifacts when the full generated export exists.
+
+## Validation
+
+Before:
+
+- A generated JSON export workflow could show CSV, Markdown, analysis JSON, and generated JSON cards together.
+- The assistant reply included an inline preview even though artifact cards already contained previews.
+- Markdown artifact filenames could inherit the source extension and appear confusing beside JSON exports.
+
+After:
+
+- The full generated tabular export is presented as the primary deliverable.
+- The supporting CSV preview remains available for quick inspection.
+- Redundant analysis JSON and default Markdown artifacts are suppressed for primary generated export flows.
+- Assistant text clearly says the generated export is the exhaustive deliverable.

+# Tabular Generated Output Progress Fix
+
+Fixed in version: **0.241.135**
+
+## Issue Description
+
+Tabular requests that asked for exhaustive JSON or CSV output could show a completed tabular progress card even though the request was still busy building structured export batches or uploading the generated artifact. From the browser and backend logs, the request could look hung for several minutes with no visible errors.
+
+## Root Cause Analysis
+
+- The tabular tool activity card only represented `TabularProcessingPlugin` tool invocations.
+- After those tool calls completed, the request could still enter the generated-output pipeline in `maybe_create_tabular_generated_output(...)` and `_generate_tabular_structured_output_entries(...)`.
+- That structured export phase could batch rows, retry model transformations, and upload a generated chat artifact without emitting thoughts or consistent backend logs.
+- Because the UI never saw activity from that phase, the tabular card could sit at 100 percent while the request was still legitimately working.
+
+## Version Implemented
+
+- **0.241.135**
+
+## Files Modified
+
+- `application/single_app/route_backend_chats.py`
+- `application/single_app/static/js/chat/chat-thoughts.js`
+- `application/single_app/config.py`
+- `functional_tests/test_workspace_tabular_trigger_and_thoughts.py`
+- `ui_tests/test_chat_tabular_thought_progress.py`
+
+## Code Changes Summary
+
+- Added tabular post-processing activity payloads and callback helpers so generated-output work can publish thoughts just like tabular tool invocations.
+- Wired the generated-output helper through both persisted-thought and streaming SSE paths.
+- Added lightweight debug logging for structured export batch preparation, batch execution, upload start, and completion.
+- Updated the tabular activity card to label mixed tool plus export work as `steps` instead of only `tool calls`, and changed the completion copy to `Tabular export ready` when post-processing activity is present.
+- Added backend and UI regression coverage for the previously silent post-processing phase.
+
+## Testing Approach
+
+- Ran `python -m py_compile application/single_app/route_backend_chats.py`.
+- Ran `functional_tests/test_workspace_tabular_trigger_and_thoughts.py`.
+- Ran `node --check application/single_app/static/js/chat/chat-thoughts.js`.
+- Ran `pytest ui_tests/test_chat_tabular_thought_progress.py -q`.
+
+## Impact Analysis
+
+- Requests that ask for exhaustive structured tabular output now show visible activity after the tabular tool pass completes.
+- Backend logs now provide checkpoints for the generated-output phase instead of going silent.
+- Users can distinguish `tabular tool phase complete` from `request fully done`, which reduces false hang reports and makes real hangs easier to diagnose.
+
+## Validation
+
+- Before: the tabular card could reach 100 percent and stay there while structured export batching or artifact upload continued silently.
+- After: the same request continues emitting tabular post-processing activity, the progress card stays active during export work, and completion text reflects export readiness instead of only workbook evidence.

+# Tabular Inline Chart Handoff Fix
+
+Fixed in version: **0.241.166**
+
+## Issue Description
+
+Users could ask tabular analysis questions that computed grouped totals successfully, but the final answer could return unsupported chart syntax such as Mermaid instead of a SimpleChat inline chart. For example, a request for category totals from a workbook followed by a pie chart could produce a Markdown table plus a plain `pie showData` code block that the chat UI does not render.
+
+## Root Cause Analysis
+
+SimpleChat inline charts render only `simplechart` fenced blocks produced by the conversation chart capability. The tabular analysis mini-kernel in `route_backend_chats.py` computes workbook aggregations through tabular tools, but grouped tabular tool results were handed to the final model as text without a deterministic chart handoff. When the model chose Mermaid syntax, the frontend correctly treated it as ordinary code because Mermaid is not part of the inline chart renderer.
+
+## Technical Details
+
+### Files Modified
+
+- `application/single_app/route_backend_chats.py`
+- `application/single_app/functions_chart_operations.py`
+- `application/single_app/config.py`
+- `functional_tests/test_tabular_inline_chart_handoff.py`
+
+### Code Changes Summary
+
+- Added deterministic conversion from successful grouped tabular invocations into conversation chart citations.
+- Supported chart handoff for both workspace-search tabular analysis and chat-uploaded tabular files.
+- Wired the handoff into both streaming and non-streaming chat response paths.
+- Strengthened reusable chart guidance to prefer SimpleChat `simplechart` blocks and avoid Mermaid, matplotlib, Vega, or other unsupported chart code when the user wants an inline chart.
+- Updated the app version from `0.241.165` to `0.241.166`.
+
+### Testing Approach
+
+- Added `functional_tests/test_tabular_inline_chart_handoff.py` to validate that grouped category totals create a `simplechart` pie citation rather than Mermaid output.
+- The test also checks that all four tabular success paths call the chart handoff helper.
+
+## Validation
+
+### Expected Behavior
+
+When a tabular analysis request asks for a chart and grouped tabular results are available, SimpleChat now appends a chart citation containing `chart_markdown` with a `simplechart` fenced block. Existing backend append logic then includes that chart block in the assistant response and streaming delta.
+
+### User Experience Improvements
+
+- Chart requests over CSV/XLSX analysis now render through the SimpleChat inline chart renderer.
+- The model can still explain the computed totals, but the visual chart no longer depends on the model choosing the exact supported fence syntax.
+
+### Impact Analysis
+
+The fix is scoped to successful grouped tabular tool results (`group_by_aggregate` and `group_by_datetime_component`). It does not add Mermaid rendering or change frontend chart behavior.

+# TABULAR RELATED DOCUMENT SCOPE FIX
+
+Fixed in version: **0.241.140**
+
+## Issue Description
+
+Tabular rows that referenced uploaded PDFs or DOCX files by filename could fail to resolve those attachments in group or public workspace chats. Users could see the filename in the CSV row, but the final tabular output and citations still behaved as if the attachment text was unavailable.
+
+## Root Cause Analysis
+
+- The related-document augmentation path in `route_backend_chats.py` depended on `group_id` or `public_workspace_id` being present in the logged tabular tool invocation parameters.
+- In real group/public chat runs, tool invocations could log `source="group"` or `source="public"` without the concrete scope ID.
+- When that happened, the related-document catalog query had no authorized scope ID to search against, so it built an empty catalog and never matched the referenced attachment filenames.
+
+## Version Implemented
+
+- **0.241.140**
+
+## Files Modified
+
+- `application/single_app/route_backend_chats.py`
+- `application/single_app/config.py`
+- `functional_tests/test_tabular_related_document_evidence.py`
+
+## Code Changes Summary
+
+- Added a fallback that recovers the active authorized group/public scope from `g.authorized_chat_context` when the tabular invocation omits the concrete scope ID.
+- Kept the fallback tied to the current authorized user and conversation before reusing that scope.
+- Added a focused regression that verifies the related-document helper can recover group/public scope IDs from the authorized chat context.
+
+## Testing Approach
+
+- Ran `pytest functional_tests/test_tabular_related_document_evidence.py`
+- Ran `python -m py_compile application/single_app/route_backend_chats.py`
+
+## Impact Analysis
+
+- Group/public tabular runs can now resolve row-level `File Name` references like `114100JosephJanuszewski.pdf` against uploaded workspace documents.
+- Resolved attachment excerpts flow back into tabular exports, prompt handoff summaries, and tool citations instead of being silently dropped.
+- The change is scoped to request-authorized chat contexts and does not widen document lookup beyond the active authorized scope.
+
+## Validation
+
+- Before: a row could reference an uploaded PDF or DOCX filename, but the related-document catalog stayed empty because the scope ID was missing from the tool invocation metadata.
+- After: the helper reuses the authorized active group/public scope, finds the matching document catalog entry, and makes that attachment available to the tabular evidence pipeline.

+# Token Export Workspace Names Fix
+
+## Issue Description
+
+Control Center Activity Trends token exports showed `Workspace Type`, `Group ID`, and `Public Workspace ID`, but did not include friendly group or public workspace names. Admins had to manually map IDs back to workspace records to understand token usage by workspace.
+
+## Root Cause Analysis
+
+Token export records were built directly from `activity_logs` token usage entries. Those logs store scoped IDs in `workspace_context`, but the export path did not resolve those IDs against the group and public workspace containers before writing CSV rows.
+
+## Fixed in version: **0.241.115**
+
+The application version is tracked in `application/single_app/config.py` and is currently `0.241.115` for this fix.
+
+## Technical Details
+
+### Files Modified
+
+*   `application/single_app/route_backend_control_center.py`
+*   `functional_tests/test_control_center_token_export_workspace_names.py`
+
+### Code Changes Summary
+
+*   Added group and public workspace name resolver helpers for Control Center reporting.
+*   Added `group_name` and `public_workspace_name` fields to raw token export records.
+*   Added `Group Name` and `Public Workspace Name` columns to token CSV exports.
+*   Added regression coverage that verifies the backend export path includes the new fields and CSV headers.
+
+### Testing Approach
+
+*   Python syntax validation with `py_compile`.
+*   Functional source regression test for token export workspace name fields.
+*   Targeted diagnostics on modified backend and test files.
+
+## Validation
+
+### Test Results
+
+*   `python -m py_compile application/single_app/route_backend_control_center.py functional_tests/test_control_center_token_export_workspace_names.py`
+*   `python functional_tests/test_control_center_token_export_workspace_names.py`
+
+### Before/After Comparison
+
+Before, token exports included workspace IDs without friendly names. After the fix, group-scoped token rows include `Group Name`, and public workspace token rows include `Public Workspace Name`, while preserving the existing ID columns for precise filtering and lookup.
+
+### User Experience Improvements
+
+Admins can now read token exports without manually cross-referencing group or public workspace IDs, making group and public workspace token reporting easier to audit and share.

+# TTS Autoplay Toggle Fix - Version 0.242.048
+
+Fixed/Implemented in version: **0.242.048**
+
+## Issue Description
+
+Turning on the chat toolbar AI voice response toggle did not automatically read new assistant messages aloud for users whose saved `ttsEnabled` preference was missing or false. The manual `Read this to me` button still worked because it invoked playback directly.
+
+## Root Cause Analysis
+
+The automatic playback path required both `ttsAutoplay` and `ttsEnabled` to be true. The chat toolbar toggle only persisted `ttsAutoplay`, while the profile settings flow was the only place that wrote `ttsEnabled`. Users who enabled voice response from chat could therefore see the toggle as enabled while auto-play remained blocked by stale playback state.
+
+## Technical Details
+
+Files modified:
+
+- `application/single_app/static/js/chat/chat-tts.js`
+- `application/single_app/config.py`
+- `functional_tests/test_chat_tts_autoplay_toggle.py`
+- `ui_tests/test_chat_tts_autoplay_toggle.py`
+
+Code changes summary:
+
+- Chat TTS initialization now treats `ttsAutoplay` as an enabled playback state for backward compatibility with stale user settings.
+- Enabling AI voice response from the chat toolbar now persists both `ttsAutoplay: true` and `ttsEnabled: true`.
+- Failed toggle saves restore both the previous autoplay state and previous TTS enabled state.
+- `config.py` version was updated to `0.242.048` for traceability.
+
+## Testing Approach
+
+Functional coverage was added in `functional_tests/test_chat_tts_autoplay_toggle.py` to validate that the source contract keeps auto-play and playback state aligned.
+
+UI coverage was added in `ui_tests/test_chat_tts_autoplay_toggle.py` to validate that enabling the chat toolbar AI voice response toggle posts both settings to `/api/user/settings`.
+
+## Impact Analysis
+
+Users can now enable AI voice response directly from chat and have new assistant messages start playback automatically. Existing users with `ttsAutoplay` already enabled but `ttsEnabled` false are normalized on the next chat load without needing to visit profile settings.
+
+## Validation
+
+Before the fix, the chat toggle could enable `ttsAutoplay` while auto-play still skipped playback because `ttsEnabled` stayed false. After the fix, the same toggle enables playback state and auto-play can call the same working TTS playback path used by the manual button.

+# TTS Live Voice Fallback Fix - Version 0.241.099
+
+Fixed/Implemented in version: **0.241.099**
+
+## Issue Description
+
+Text-to-speech playback could fail with a 500 response when a user's saved voice was not supported by the configured Azure Speech resource. One observed failure was Azure rejecting `en-US-Ava:DragonHDLatestNeural` with `Unsupported voice`, even though speech-to-text was configured correctly.
+
+## Root Cause Analysis
+
+The TTS voice picker returned a hardcoded DragonHD voice list. That list was treated as universally supported, but Azure Speech voice availability can vary by resource, region, SKU, rollout state, and voice family. A stale saved `ttsVoice` setting was then sent directly to Azure during synthesis.
+
+## Technical Details
+
+Files modified:
+
+- `application/single_app/route_backend_tts.py`
+- `application/single_app/config.py`
+- `functional_tests/test_tts_voice_fallback.py`
+
+Code changes summary:
+
+- `/api/chat/tts/voices` now retrieves the live voice list from the configured Azure Speech resource and caches it briefly.
+- The endpoint returns `default_voice`, `source`, and `warning` metadata so callers can tell whether live Azure voices or fallback voices were returned.
+- `/api/chat/tts` validates requested/saved voices against the live list and falls back to a preferred supported voice or the first available voice.
+- Unsupported-voice cancellations now trigger one refreshed voice lookup and retry with a different fallback voice before returning an error.
+- Speed-adjusted SSML synthesis now escapes text and voice values before embedding them in SSML.
+- `config.py` version was updated to `0.241.099` for traceability.
+
+## Testing Approach
+
+Functional coverage was added in `functional_tests/test_tts_voice_fallback.py` to validate:
+
+- Supported requested voices are preserved.
+- Stale DragonHD saved voices fall back to a supported live voice.
+- Retry fallback skips a voice Azure already rejected.
+- Azure unsupported-voice cancellation details are detected.
+- Static backup voices avoid DragonHD-only names.
+
+## Impact Analysis
+
+Users no longer need to manually clear a stale TTS voice setting after Azure rejects it. The Profile voice picker should reflect voices available to the configured Speech resource, while chat playback can still proceed with a safe fallback if the saved voice becomes unavailable later.
+
+## Validation
+
+Before the fix, a saved unsupported voice caused `/api/chat/tts` to return 500 and the browser displayed a TTS error. After the fix, the backend chooses a supported fallback voice and retries unsupported-voice failures once with a refreshed live voice list.

+# TTS Speech Speed Prosody Rate Fix - Version 0.241.102
+
+Fixed/Implemented in version: **0.241.102**
+
+## Issue Description
+
+Text-to-speech speeds from `1.1x` through `2.0x` sounded the same during chat playback and voice preview, making the faster-speed slider settings effectively indistinguishable.
+
+## Root Cause Analysis
+
+The backend converted the user speed multiplier directly into an SSML percentage. For example, `1.1x` became `rate="110%"` and `2.0x` became `rate="200%"`. Azure Speech treats percentage rates as relative changes from the default speaking rate, so these values were interpreted as oversized speed increases and clamped near the same upper limit.
+
+## Technical Details
+
+Files modified:
+
+- `application/single_app/route_backend_tts.py`
+- `application/single_app/config.py`
+- `functional_tests/test_tts_speech_speed_prosody_rate.py`
+
+Code changes summary:
+
+- Added TTS speed normalization to parse, validate, and clamp incoming speed multipliers to Azure Speech's supported `0.5x` to `2.0x` range.
+- Converted speed multipliers into Azure Speech relative prosody percentages, such as `1.1x` to `+10.00%` and `2.0x` to `+100.00%`.
+- Kept `1.0x` on normal plain-text synthesis while non-default speeds continue to use SSML.
+- Updated `config.py` version to `0.241.102` for traceability.
+
+## Testing Approach
+
+Functional coverage was added in `functional_tests/test_tts_speech_speed_prosody_rate.py` to validate:
+
+- Faster speeds from `1.1x` to `2.0x` generate distinct relative increase percentages.
+- Slower speeds generate negative relative percentages.
+- Normal speed maps to Azure's default prosody rate.
+- Out-of-range speeds are clamped to the supported range.
+- Invalid speed payloads raise a `ValueError` that the route returns as a client parameter error.
+
+## Impact Analysis
+
+Users should now hear distinct playback speeds across the full profile slider range. Saved speed preferences require no migration because the stored user setting remains the same multiplier value.
+
+## Validation
+
+Before the fix, values like `1.1x`, `1.5x`, and `2.0x` generated oversized SSML rates that Azure could clamp together. After the fix, those settings generate `+10.00%`, `+50.00%`, and `+100.00%` respectively, allowing Azure Speech to synthesize progressively faster audio.

+# URL Access Button State Fix
+
+Fixed in version: **0.241.084**
+
+## Issue Description
+The URL Access button could remain selected after a user started a new conversation or switched to another conversation, even when the new composer context did not intentionally enable URL Access.
+
+## Root Cause
+URL Access selection was tracked only through the button's local `active` class. Conversation creation and conversation selection updated chat content and conversation metadata, but did not notify the chat input action controls to clear per-message source action state.
+
+## Technical Details
+- Added a chat input reset handler that clears URL Access and Deep Research selected state when the active conversation context changes.
+- Added a `chat:conversation-context-changed` event from conversation selection and manual new conversation creation.
+- Kept URL Access and Deep Research `aria-pressed` values synchronized with their visible selected state.
+- Added UI regression coverage in `ui_tests/test_chat_url_access_button_reset.py`.
+- Updated `config.py` version to `0.241.084`.
+
+## Validation
+- JavaScript syntax validation confirms the changed chat modules parse successfully.
+- The UI regression validates that URL Access becomes inactive after selecting another conversation and after clicking New Conversation.
+
+## Impact
+URL Access now behaves as a per-message action instead of leaking selected state into unrelated conversation contexts. Users can switch chats or start fresh without accidentally sending URL Access enabled from the prior context.

+# URL Access HTML Extraction Fix
+
+Fixed in version: **0.241.083**
+
+## Issue Description
+URL Access could report `URL Access did not add page evidence` for valid public pages, including GitHub repository pages, even though the URL Access request was enabled and the pasted URL was reviewed.
+
+## Root Cause
+The shared Source Review HTML cleanup step decomposed hidden and control nodes, then continued iterating over nested BeautifulSoup tags that had already been removed from the parse tree. Calling `element.get(...)` on one of those decomposed tags raised an `AttributeError`, causing the page to be recorded as an `unexpected_error` skip with no evidence message.
+
+## Technical Details
+- Updated `functions_source_review.py` so `_remove_non_evidence_nodes()` skips already-decomposed tags during cleanup.
+- Updated URL Access/Source Review result handling so all-skipped URL reviews include a concrete `skipped_reason` for troubleshooting.
+- Updated the evidence system message to tell selected agents not to call web or HTTP tools for the same reviewed pasted URL unless a fresh fetch is explicitly needed.
+- Added regression coverage in `functional_tests/test_source_review_security.py` for nested hidden/control HTML that previously failed extraction.
+- Updated `config.py` version to `0.241.083`.
+
+## Validation
+- Functional Source Review tests validate that nested removed nodes no longer fail evidence extraction.
+- Direct URL Access fetch validation against `https://github.com/microsoft/simplechat` confirms that URL Access now produces reviewed page evidence and a system evidence message without requiring an agent.
+
+## Impact
+URL Access now works for normal model-only chats when a pasted page contains nested hidden or control markup. Selected agents receive the same URL Access evidence and are instructed to avoid duplicating the Smart HTTP fetch for already-reviewed pasted URLs.

+# User Profile IDOR Authorization Fix
+
+Fixed/Implemented in version: **0.241.203**
+
+## Issue Description
+
+The `/api/user/info/<user_id>` and `/api/user/profile-image/<user_id>` endpoints accepted a caller-supplied Entra object ID and read the matching user-settings document directly from Cosmos DB. The routes were protected by login and User/Admin role decorators, but they did not verify that the authenticated caller was authorized to view the target user's profile metadata.
+
+## Root Cause Analysis
+
+The affected route handlers bypassed the existing user-settings access guard and called `cosmos_user_settings_container.read_item(...)` with the URL path value as both item ID and partition key. That created a horizontal authorization gap for profile metadata lookup by known user ID.
+
+## Technical Details
+
+Files modified:
+
+- `application/single_app/route_backend_users.py`
+- `scripts/check_broken_access_control.py`
+- `functional_tests/test_user_profile_idor_authorization.py`
+- `application/single_app/config.py`
+
+Code changes summary:
+
+- Added a user-profile authorization boundary before user-settings document reads.
+- Allowed profile lookup only for the same user, Admin callers, shared group relationships, shared document relationships, or shared collaboration conversation relationships.
+- Replaced direct route-level user-settings reads with `_read_authorized_user_profile_document(...)`.
+- Removed full user document console logging from `/api/user/info/<user_id>`.
+- Extended the Broken Access Control checker to flag direct `cosmos_user_settings_container.read_item(...)` calls from request-derived `user_id` values in `route_backend_users.py`.
+
+## Validation
+
+Testing approach:
+
+- Added a focused functional regression test that verifies self lookup is allowed, unrelated low-privilege lookup is denied before the Cosmos user-settings read, Admin lookup is allowed, relationship-based lookups remain allowed, and the static BAC checker catches the old direct-read pattern.
+
+Before/after comparison:
+
+- Before: any authenticated User/Admin role holder could request another known user ID and receive profile metadata.
+- After: profile document reads occur only after object-level authorization succeeds; unauthorized lookups receive a generic not-found/access-denied response.
+
+Related version update:
+
+- `application/single_app/config.py` was incremented from `0.241.201` to `0.241.203` across the endpoint authorization fix and generalized guardrail follow-up.

+# Visio Extensions Import Fix
+
+Fixed/Implemented in version: **0.241.079**
+
+## Issue Description
+
+Application startup failed while importing enhanced citation routes because `route_enhanced_citations.py` imported `VISIO_EXTENSIONS` from `config.py`, but the shared constant was not defined.
+
+## Root Cause Analysis
+
+Visio ingestion and enhanced citation preview support were added around a shared extension concept, and downstream code referenced `VISIO_EXTENSIONS`. The config module still only declared base document, tabular, image, video, and audio extension sets, so Python raised an `ImportError` before Flask route registration could complete.
+
+## Version Implemented
+
+0.241.079
+
+## Technical Details
+
+### Files Modified
+
+- `application/single_app/config.py`
+- `functional_tests/test_visio_extensions_config.py`
+- `docs/explanation/features/VISIO_INGESTION.md`
+- `docs/explanation/fixes/VISIO_EXTENSIONS_IMPORT_FIX.md`
+
+### Code Changes Summary
+
+- Added `VISIO_EXTENSIONS = {'vsdx'}` to the shared configuration module.
+- Included Visio extensions in `get_allowed_extensions()` so `.vsdx` uploads use the same shared allow-list as ingestion and enhanced citations.
+- Bumped `application/single_app/config.py` to `VERSION = "0.241.079"`.
+- Added a functional regression test that parses the relevant Python files and verifies the config export, upload allow-list inclusion, and enhanced citation import.
+
+### Testing Approach
+
+- Ran the new Visio extension config functional test.
+- Ran Python compilation for the modified config and test files.
+- Validated the enhanced citation import path used by app startup.
+
+### Impact Analysis
+
+The app can import and register enhanced citation routes again, and `.vsdx` uploads are consistently recognized by the shared allowed-extension configuration.
+
+## Validation
+
+### Test Results
+
+- `python functional_tests/test_visio_extensions_config.py` passes.
+- `python -m py_compile application/single_app/config.py functional_tests/test_visio_extensions_config.py` passes.
+- `python -c "from route_enhanced_citations import register_enhanced_citations_routes; from config import VISIO_EXTENSIONS; print(VISIO_EXTENSIONS)"` succeeds.
+
+### Before/After Comparison
+
+Before, importing `route_enhanced_citations.py` failed with `ImportError: cannot import name 'VISIO_EXTENSIONS' from 'config'`. After, the constant is exported from config and reused by allowed-upload logic.
+
+### User Experience Improvements
+
+Administrators and users can start the app with enhanced citations enabled and continue using native Visio `.vsdx` ingestion and citation preview flows.

+# Visio Preview Fidelity Fix
+
+Fixed/Implemented in version: **0.241.078**
+
+## Issue Description
+
+The initial Visio enhanced-citation preview proved that `.vsdx` pages could be parsed and rendered, but it produced a simplified structural sketch. The preview omitted much of the real diagram fidelity, including richer connector lines, embedded icons, and stencil artwork.
+
+## Root Cause Analysis
+
+The first renderer intentionally used a lightweight parser-only approach. It drew text-bearing shapes as generic boxes and connected known endpoints, but did not preserve enough nested group transforms, master stencil geometry, curve rows, label placement, or foreign image references to resemble Visio's actual view.
+
+## Version Implemented
+
+0.241.078
+
+## Technical Details
+
+### Files Modified
+
+- `application/single_app/config.py`
+- `application/single_app/functions_visio.py`
+- `functional_tests/test_visio_ingestion_preview.py`
+- `ui_tests/test_chat_visio_citation_modal.py`
+- `docs/explanation/features/VISIO_INGESTION.md`
+- `docs/explanation/release_notes.md`
+
+### Code Changes Summary
+
+- Improved the structural fallback renderer by preserving nested shape coordinates, connector endpoints, geometry rows, selected master stencil geometry, and supported embedded media references.
+- Removed the optional LibreOffice conversion branch after confirming Azure Linux `tdnf` does not provide LibreOffice packages in the app builder image.
+- Added rendering for supported VSDX geometry path rows: `MoveTo`, `LineTo`, `RelMoveTo`, `RelLineTo`, `RelCubBezTo`, `RelQuadBezTo`, elliptical arc endpoint approximation, and `Ellipse`.
+- Added preview-only expansion of master stencil shapes so citation previews can draw richer icon geometry while ingestion chunks remain focused on page-level diagram content.
+- Improved label placement for icon-backed shapes and dashed container labels based on the Microsoft Visio exported SVG/PDF reference files.
+- Improved elliptical arc rows with smooth curve approximation and skipped duplicate center-to-center fallback connectors when explicit connector geometry is available.
+- Added bounded supersampling for smoother PNG output without requiring external rendering tools.
+- Bumped `application/single_app/config.py` to `VERSION = "0.241.078"`.
+
+### Testing Approach
+
+- Re-ran the Visio functional parser and preview rendering test against `artifacts/architecture.vsdx`.
+- Re-ran Python compilation and JavaScript syntax checks for affected files.
+- Kept UI test coverage for the Visio citation modal path.
+
+### Impact Analysis
+
+Users get a richer built-in Visio structural preview than the original sketch renderer without adding a large external office-suite dependency. Original `.vsdx` downloads remain unchanged.
+
+## Validation
+
+### Test Results
+
+- `python functional_tests/test_visio_ingestion_preview.py` passes.
+- `python -m py_compile` passes for affected Python files.
+- `node --check application/single_app/static/js/chat/chat-enhanced-citations.js` passes.
+
+### Before/After Comparison
+
+Before, Visio previews rendered as sparse text boxes with limited connector context. After, previews use a parser renderer that includes more actual page geometry paths, master stencil artwork, dashed containers, media, and connector information.
+
+### User Experience Improvements
+
+Citation previews are more recognizable as Visio diagrams while remaining dependency-light for the existing app container.

+# Web Research External Retrieval Priority Fix
+
+Fixed/Implemented in version: **0.250.002**
+
+## Issue Description
+
+Explicit Web, URL Access, and Deep Research chat turns could be interrupted by the conversation citation experience. When workspace search was not selected, the chat backend could still inspect prior grounded conversation history and search previously cited workspace documents before honoring the external retrieval request.
+
+## Root Cause Analysis
+
+The standard and streaming chat routes used the history-grounded document fallback whenever workspace search was disabled. That fallback did not distinguish between a plain follow-up question and a turn where the user had explicitly selected Web, URL Access, or Deep Research.
+
+Chat-upload workspace documents were also auto-merged into normal chat search context before external retrieval ran, which could make a Web or Research turn behave like a document-grounded turn.
+
+## Technical Details
+
+Files modified:
+
+- `application/single_app/route_backend_chats.py`
+- `application/single_app/config.py`
+- `functional_tests/test_chat_history_grounded_follow_up_fix.py`
+
+Code changes:
+
+- Added `explicit_external_retrieval_requested` handling for Web, URL Access, Source Review, and Deep Research requests.
+- Added `_should_auto_merge_chat_upload_workspace_context` so uploaded workspace documents are not auto-linked into explicit external-retrieval-only turns.
+- Updated history-grounded fallback guards in both standard and streaming chat paths so Web, URL Access, or Deep Research takes precedence over previously grounded document fallback.
+- Updated `should_apply_history_grounding_message` so the final prompt does not add workspace-only grounding instructions during external retrieval turns.
+- Updated conversation history preparation so prior assistant citation context is not injected into explicit Web, URL Access, or Deep Research turns.
+- Updated `config.py` from `0.250.001` to `0.250.002`.
+
+## Testing Approach
+
+Updated `functional_tests/test_chat_history_grounded_follow_up_fix.py` to verify:
+
+- Explicit external retrieval disables the history-grounding prompt.
+- Web, URL Access, Source Review, and Deep Research all count as external retrieval.
+- Chat-upload workspace context is not auto-merged for external-only turns.
+- Prior assistant document citation context is omitted from external-retrieval history preparation.
+- Both standard and streaming chat paths use the new history-grounded document fallback guard.
+
+## Impact Analysis
+
+When users explicitly select Web, URL Access, or Deep Research, those sources now take priority. Existing workspace search behavior is preserved when document search is explicitly active, and assigned knowledge workspace context can still participate when a selected agent requires it.
+
+## Validation
+
+Before the fix, a Web or Research request in a conversation with prior document citations could trigger history-grounded document assessment and workspace search first.
+
+After the fix, explicit Web, URL Access, or Deep Research requests skip the history-grounded document fallback and proceed through external retrieval.

+# Web Search Chat Agent Isolation Fix
+
+Fixed/Implemented in version: **0.241.073**
+
+## Issue Description
+
+Fresh installs could interrupt a Web Search streaming response when no chat agent was selected. Web Search uses its configured Azure AI Foundry agent only to retrieve current web evidence, but the chat response path could still fall back to a loaded Semantic Kernel default or first agent afterward.
+
+## Root Cause Analysis
+
+The streaming and non-streaming chat paths treated the presence of loaded agents as enough reason to select a default or first chat agent. On environments where the Web Search Foundry agent was present in the loaded agent set, an otherwise model-only Web Search request could accidentally enter chat-agent and Assigned Knowledge related paths.
+
+## Version Implemented
+
+- Application version updated in `application/single_app/config.py` from `0.241.072` to `0.241.073`.
+
+## Technical Details
+
+### Files Modified
+
+- `application/single_app/route_backend_chats.py`
+- `application/single_app/config.py`
+- `functional_tests/test_web_search_without_agent_assigned_knowledge.py`
+
+### Code Changes Summary
+
+- Added explicit chat-agent selection helpers so empty or unrelated `agent_info` payloads do not enable agent mode.
+- Removed default-agent and first-agent fallbacks from chat response selection when no chat agent is selected.
+- Kept Web Search Foundry execution isolated through the existing `perform_research_web_searches()` and `execute_foundry_agent()` path.
+- Prevented unresolved chat-agent selections from writing misleading selected-agent metadata.
+
+### Testing Approach
+
+- Added a static functional regression test that verifies the undefined `agent_knowledge_binding` name is absent and default/first chat-agent fallbacks remain removed.
+- Validated that Web Search still retains its dedicated Foundry execution path.
+
+## Impact Analysis
+
+Web Search remains available through the configured Foundry search agent, while the final answer generation stays model-only unless the user or saved settings explicitly select a chat agent. This prevents Assigned Knowledge policy from applying to Web Search-only requests.
+
+## Validation
+
+Run:
+
+```bash
+python functional_tests/test_web_search_without_agent_assigned_knowledge.py
+python -m py_compile application/single_app/route_backend_chats.py functional_tests/test_web_search_without_agent_assigned_knowledge.py

+# Workflow Access Control Fix
+
+Fixed in version: **0.241.106**
+
+Related config.py version update: `application/single_app/config.py` was incremented to `0.241.106`.
+
+## Issue Description
+
+Personal workflows were exposed to any signed-in user whenever the workflow UI was present. The admin toggle existed in the settings page, but the setting was not persisted in the Admin Settings POST payload and there was no optional app role gate for organizations that need tighter workflow access control.
+
+## Root Cause Analysis
+
+- `allow_user_workflows` defaulted to enabled and several code paths treated a missing setting as enabled.
+- Admin Settings rendered the workflow toggle but did not save it into the app settings document.
+- Workflow routes only checked the global feature setting and did not evaluate a per-user role requirement.
+- Workspace and chat templates rendered workflow affordances from the raw public setting instead of the effective user policy.

+# Workflow Activity Current Tab Navigation Fix
+
+Fixed in version: **0.241.189**
+
+Related version update:
+- `application/single_app/config.py` reports version `0.241.189`.
+
+## Issue Description
+
+Clicking the workflow `Activity` button could open the activity view in a new tab and also navigate the current workspace tab to the same activity view. Users lost the workflow list context even though the action was intended to preserve it.
+
+## Root Cause Analysis
+
+The workflow Activity click handler called `window.open(activityState.url, "_blank", "noopener")` and then used `window.location.href = activityState.url` when the returned window handle was falsy. Some browsers can return a null handle when `noopener` is used even though the new tab opens successfully. That made the fallback run and changed the current tab too.
+
+## Technical Details
+
+Files modified:
+- `application/single_app/static/js/workspace/workspace_workflows.js`
+- `application/single_app/config.py`
+- `functional_tests/test_workflow_activity_new_tab_navigation.py`
+- `ui_tests/test_workspace_workflows_tab.py`
+
+Code changes summary:
+- Activity opens `about:blank` synchronously in a new tab.
+- The new tab clears `opener` and then navigates to the workflow activity URL.
+- The current-tab `window.location.href` fallback was removed.
+- If pop-ups are blocked, the UI shows a warning toast instead of navigating the current workspace tab.
+
+Testing approach:
+- Added a focused functional contract test that rejects `window.location.href = activityState.url` in the workflow Activity handler.
+- Extended the personal workflows UI test to assert the Activity action opens a new tab while the original page remains on the workspace URL.
+
+## Validation
+
+Before:
+- Activity could open `/workflow-activity` in both a new tab and the current workspace tab.
+
+After:
+- Activity opens only in a new tab.
+- Current workspace context remains unchanged.
+- Blocked pop-ups show an actionable warning toast.
+
+User experience improvement:
+- Users can inspect workflow activity while keeping the workflow list available in the original tab.

+# Workflow Activity Dark Mode And Layout Fix
+
+Fixed in version: **0.241.043**
+
+## Issue Description
+
+The workflow activity timeline and detail view used light-only surface colors, which made the page hard to read in dark mode. The page also inherited the shared fixed-width container shell, so when the left navigation sidebar was expanded the workflow activity layout lost too much horizontal room and the detail panel became cramped.
+
+## Root Cause Analysis
+
+- The workflow activity stylesheet used hardcoded light backgrounds, borders, and scrollbar colors instead of theme-aware variables.
+- The page rendered inside the shared `#main-content.container` shell without a page-specific width override, so the sidebar padding was applied on top of the Bootstrap container max width.
+- The layout issue became most noticeable on large screens with the sidebar expanded because the timeline and detail columns had to compete inside a shell that was narrower than the viewport.
+
+## Technical Details
+
+### Files Modified
+
+- `application/single_app/static/css/workflow-activity.css`
+- `application/single_app/static/js/workflow/workflow-activity.js`
+- `application/single_app/config.py`
+- `functional_tests/test_workflow_activity_dark_mode_layout_contract.py`
+- `ui_tests/test_workflow_activity_dark_mode_layout.py`
+
+### Code Changes Summary
+
+- Added theme-aware workflow activity surface, border, connector, and scrollbar tokens with explicit dark-mode overrides.
+- Updated the workflow activity cards, panels, empty state, detail blocks, and event history items to use those theme tokens.
+- Added a page-specific `workflow-activity-main-content` layout mode so the workflow activity page can break out of the shared container max width.
+- Kept the widened shell compatible with the existing sidebar toggle behavior by relying on the `sidebar-padding` class already managed by the base layout.
+
+## Testing Approach
+
+- Added `functional_tests/test_workflow_activity_dark_mode_layout_contract.py` to assert the CSS and JavaScript contract for dark mode and widened layout behavior.
+- Added `ui_tests/test_workflow_activity_dark_mode_layout.py` to validate the page remains readable in dark mode and roomy with simulated sidebar padding in a browser workflow.
+
+## Validation
+
+### Test Results
+
+- `functional_tests/test_workflow_activity_dark_mode_layout_contract.py` passes locally.
+- The UI regression was added but may require `SIMPLECHAT_UI_BASE_URL` and `SIMPLECHAT_UI_STORAGE_STATE` to run in an authenticated environment.
+
+### User Experience Improvements
+
+- Workflow activity cards, timeline connectors, and detail surfaces remain readable in dark mode.
+- The workflow activity page uses the available viewport width more effectively when the left navigation sidebar is expanded.
+- The detail panel retains more usable horizontal space while preserving the workflow timeline layout.

+# Workflow Activity Realtime And Layout Fix
+
+Fixed in version: **0.241.041**
+
+## Issue Description
+
+The workflow activity page was not reliably reflecting live changes while a workflow was still running. In practice, users could end up refreshing the page to see newly created or updated timeline entries. The page layout also allowed the whole page to scroll, which made the top run summary and the activity detail pane move out of view while watching a live run. A follow-up issue also left the timeline without a usable manual scrollbar and prevented it from reliably auto-following the newest events.
+
+## Root Cause Analysis
+
+- The frontend only opened the SSE connection when no explicit `runId` was present, so a directly opened running run would not subscribe to live updates.
+- The activity page relied on full-page scrolling instead of a fixed-height viewport with an internal timeline scroller.
+- The timeline container still stretched to its content height because the activity layout row was not forcing the panel to fill the available height.
+- The timeline did not reliably follow the newest activity card while the page was in live-follow mode, and it did not expose a dependable manual scrollbar for navigating older entries.
+
+## Technical Details
+
+### Files Modified
+
+- `application/single_app/static/js/workflow/workflow-activity.js`
+- `application/single_app/static/css/workflow-activity.css`
+- `application/single_app/templates/workflow_activity.html`
+- `application/single_app/route_backend_workflows.py`
+- `application/single_app/config.py`
+- `functional_tests/test_workflow_activity_view_feature.py`
+
+### Code Changes Summary
+
+- The activity page now keeps SSE enabled for running workflow views even when a `runId` is explicitly present.
+- The SSE polling cadence was tightened to improve perceived real-time updates.
+- The page now uses a fixed-height viewport with an internal timeline scroller.
+- The activity layout now stretches the timeline panel to the available viewport height so the internal scroller becomes active.
+- The timeline now exposes a visible scrollbar and automatically follows the newest activity while live-follow is active.
+- Manual scrolling temporarily releases live-follow until the user returns to the bottom of the timeline.
+- The top workflow summary area and the right-side detail pane now stay in place while the timeline scrolls.
+
+## Testing Approach
+
+- Extended `functional_tests/test_workflow_activity_view_feature.py` with a running-snapshot regression case.
+- Verified the workflow activity functional test passes after the fix.
+
+## Validation
+
+### Test Results
+
+- `functional_tests/test_workflow_activity_view_feature.py` passes with the added running-state assertion.
+
+### User Experience Improvements
+
+- New workflow activities appear without needing a page refresh.
+- Long live runs can be watched from a scrolling timeline that stays anchored to the newest activity.
+- The top run summary and right-side detail pane remain visible while monitoring the run.

+# Workflow Agent Selection Fix (v0.241.024)
+
+Fixed/Implemented in version: **0.241.024**
+
+## Issue Summary
+
+The Personal Workflows modal could show `No agents available` even when the user already had personal agents available in the workspace.
+
+## Root Cause
+
+- The workflow modal expected `/api/user/agents` to return a wrapped payload shaped like `{ "agents": [...] }`.
+- The existing user-agents API returns a bare JSON array instead.
+- The modal also cached failed or empty agent loads for the rest of the page session, so a temporary failure or earlier empty response could persist until a full page refresh.
+
+## Files Modified
+
+- `application/single_app/static/js/workspace/workspace_workflows.js`
+- `ui_tests/test_workspace_workflows_tab.py`
+- `functional_tests/test_workflow_agent_selection_fix.py`
+- `application/single_app/config.py`
+
+## Code Changes Summary
+
+1. Updated workflow agent loading to accept both a bare array response and a wrapped `agents` response.
+2. Changed failed agent loads to remain retryable instead of permanently caching an empty result.
+3. Forced the workflow modal to refresh the agent list whenever it opens.
+4. Updated the workflow UI test stub to use the real bare-array user agents response shape.
+
+## Validation
+
+- Added `functional_tests/test_workflow_agent_selection_fix.py` to verify the response-shape handling and modal refresh behavior.
+- Updated `ui_tests/test_workspace_workflows_tab.py` so the workflow modal regression test reflects the actual `/api/user/agents` payload format.
+
+## Impact
+
+- Users with existing personal agents can now select them while creating or editing workflows.
+- Reopening the workflow modal after a transient load failure or after creating agents on the same page can repopulate the dropdown without requiring a full reload.

+# Workflow Alert Enrichment Summary Fix
+
+## Overview
+
+Fixed/Implemented in version: **0.241.055**
+
+Workflow priority alerts were surfacing raw workflow response preview text in the global alert modal. When an agent completed the alert workflow but mentioned a failed sub-step, the modal summary focused on the failure text instead of the alert itself and the enrichments that did succeed. The first refinement fixed the failure-text issue, but the alert header could still inherit markdown or workflow-task wording, and the detail panel still read like a raw tool dump.
+
+## Root Cause
+
+The workflow runner built workflow notifications from `run_record['response_preview']` and `run_record['error']` only. The notification modal already supported explicit alert metadata fields, but the backend was not populating them. After that metadata was added, the content builder still preferred generic extracted headings before richer conversation titles and flattened every successful enrichment into one long detail paragraph.
+
+## Files Modified
+
+- `application/single_app/functions_workflow_runner.py`
+- `application/single_app/static/js/notifications.js`
+- `application/single_app/config.py`
+- `functional_tests/test_workflow_priority_alerts.py`
+- `ui_tests/test_workflow_priority_alert_modal.py`
+
+## Code Changes Summary
+
+- Added backend helpers to sanitize markdown from alert titles and derive concise titles from created conversations before falling back to workflow reply text.
+- Replaced the flat enrichment detail dump with structured `Focus`, `Ready now`, and `Supporting items` sections.
+- Prioritized enrichment-focused copy over raw `response_preview` text for successful workflow alerts.
+- Persisted explicit `alert_title`, `alert_summary`, and `alert_detail` metadata on workflow priority notifications.
+- Updated the notification modal to preserve line breaks in the structured detail copy and prefer the explicit alert metadata fields before falling back to legacy preview and error content.
+
+## Testing Approach
+
+- Extended `functional_tests/test_workflow_priority_alerts.py` to validate the new enrichment-first alert content builder.
+- Updated `ui_tests/test_workflow_priority_alert_modal.py` to verify the browser modal prefers explicit alert metadata over legacy failure preview text.
+
+## Impact Analysis
+
+- Successful workflow alerts now describe the alert subject and the enrichments that completed.
+- Failure text is still preserved as a fallback when there is no richer alert metadata to show.
+- Existing notification consumers remain compatible because legacy `response_preview` and `error` metadata are still stored.
+
+## Validation
+
+- Before: the workflow alert modal could show failure-oriented preview text such as unavailable Teams meeting creation even when the workflow had already produced useful alert enrichments.
+- After: the modal shows an alert-specific title plus concise, actionable summary/detail text, while preserving the same deep-link and mark-as-read behavior.

+# Workflow Container Config Import Fix (v0.241.026)
+
+Fixed/Implemented in version: **0.241.026**
+
+## Issue Summary
+
+SimpleChat could fail during startup when the workflow scheduler imported `functions_personal_workflows.py` because `config.py` exported `cosmos_personal_workflow_container` while the workflow module imported `cosmos_personal_workflows_container`.
+
+## Root Cause
+
+- The workflow definitions container in `config.py` used a singular export name that did not match the plural symbol imported by the workflow helpers.
+- The manual container definitions also used partition keys that did not match the workflow storage code.
+- `functions_personal_workflows.py` reads, queries, and deletes both workflow definitions and workflow runs with `partition_key=user_id`, so `/id` and `/workflow_id` partition keys would have broken workflow CRUD even after the import error was resolved.
+
+## Files Modified
+
+- `application/single_app/config.py`
+- `functional_tests/test_personal_workflows_feature.py`
+- `functional_tests/test_workflow_agent_selection_fix.py`
+- `functional_tests/test_workflow_container_config_fix.py`
+
+## Code Changes Summary
+
+1. Renamed the exported workflow definitions container to `cosmos_personal_workflows_container` so it matches the runtime import contract.
+2. Switched both workflow containers to `/user_id` partition keys so reads, writes, queries, and deletes line up with the workflow helper code.
+3. Removed the singular workflow-container alias so the repo now follows the one-name-per-container rule consistently.
+4. Added focused regression coverage for the config export and partition-key contract.
+
+## Validation
+
+- Targeted functional tests now verify the plural workflow export name and the `/user_id` partition keys.
+- The workflow startup import path can now resolve `functions_personal_workflows.py` without the missing-config-symbol failure.
+
+## Impact
+
+- The app can start with workflow support enabled.
+- Workflow definitions and workflow runs now use the same user-scoped partitioning assumed by the workflow storage helpers.
+- The fix avoids a second runtime failure mode where CRUD would have broken even if the original import error had been patched locally.

+# Workflow List Horizontal Scroll Fix
+
+Fixed in version: **0.241.045**
+
+## Issue Description
+
+The personal workspace workflow list showed a horizontal scrollbar on desktop even when only a single workflow row was visible. The scroll came from rigid column sizing in the list table, especially the oversized actions column.
+
+## Root Cause Analysis
+
+- The workflow list table used percentage-based columns plus a large hard minimum width on the actions column.
+- The new labeled workflow buttons made that large minimum width easier to hit, so the `.table-responsive` wrapper started exposing horizontal overflow on normal desktop widths.
+- The list layout did not use a fixed-width table contract, which made the browser keep honoring the minimum widths instead of distributing the available space predictably.
+
+## Technical Details
+
+### Files Modified
+
+- `application/single_app/templates/workspace.html`
+- `application/single_app/static/js/workspace/workspace_workflows.js`
+- `application/single_app/config.py`
+- `functional_tests/test_workflow_list_horizontal_scroll_fix.py`
+- `ui_tests/test_workspace_workflow_list_no_horizontal_scroll.py`
+
+### Code Changes Summary
+
+- Added a fixed-width layout contract for the workflows list table on desktop.
+- Removed the oversized actions-column minimum width that was forcing the table wider than its card.
+- Allowed the workflow action buttons to wrap within their cell instead of forcing a single unbroken button row.
+- Kept mobile behavior flexible by switching the workflows table back to `table-layout: auto` on smaller viewports.
+
+## Testing Approach
+
+- Added `functional_tests/test_workflow_list_horizontal_scroll_fix.py` to assert the workflow table layout contract and version update.
+- Added `ui_tests/test_workspace_workflow_list_no_horizontal_scroll.py` to validate that the desktop workflow list no longer overflows horizontally while keeping the workflow actions visible.
+
+## Validation
+
+### Test Results
+
+- `functional_tests/test_workflow_list_horizontal_scroll_fix.py` passes locally.
+- The browser UI regression was added but requires `SIMPLECHAT_UI_BASE_URL` and `SIMPLECHAT_UI_STORAGE_STATE` to run in an authenticated environment.
+
+### User Experience Improvements
+
+- The workflow list fits within the workspace card on desktop without showing a horizontal scrollbar.
+- Workflow actions remain available in the list row because the buttons now wrap within the available cell width.
+- Mobile behavior stays flexible instead of hard-locking the table to a desktop layout.

+# Workflow Visualization Conversation Mirror Fix
+
+Fixed in version: **0.241.052**
+
+## Issue Description
+
+Workflow runs could report that they created an inline visualization such as an Azure Maps view, but the visualization never appeared in either of the places users actually needed it:
+
+1. the workflow conversation itself
+2. the personal or collaborative conversation the workflow created during the run
+
+The result was a text-only assistant reply that said a map had been created even though the rendered map card was missing from both conversations.
+
+## Root Cause Analysis
+
+- Agent workflow execution stored only the assistant reply text in `functions_workflow_runner.py` and discarded the plugin invocation payloads that normal chat persists as `agent_citations`.
+- Inline maps render from structured citation payloads such as `render_type` plus `map_payload`, not from plain text.
+- Created conversations seeded through the SimpleChat plugin received only the initial user-authored message, so there was no assistant-side visualization payload to render there either.
+- Collaborative conversations do not rely on workflow-chat assistant artifact hydration in the same way as personal chats, so mirrored visualization payloads need to be present directly on the collaboration message.
+
+## Version Implemented
+
+- **0.241.052**
+
+## Files Modified
+
+- `application/single_app/functions_workflow_runner.py`
+- `application/single_app/config.py`
+- `functional_tests/test_workflow_visualization_conversation_mirroring_fix.py`
+- `functional_tests/test_scope_lock_collaboration_unlock_fix.py`
+
+## Code Changes Summary
+
+- Added workflow-side extraction of detailed plugin invocations and converted them into `agent_citations` for agent workflow runs.
+- Persisted workflow assistant citation artifacts on the workflow conversation assistant message so inline maps can render in the workflow conversation itself.
+- Added a workflow visualization mirroring path that identifies newly created SimpleChat conversations and posts a mirrored assistant response into them.
+- Mirrored visualization payloads directly into collaborative conversations with `mirror_source_message_to_collaboration(...)` and into personal conversations with a dedicated assistant-message persistence helper.
+- Scoped created-conversation mirroring to visualization-style citations so the handoff stays focused on renderable outputs instead of copying every tool invocation.
+
+## Testing Approach
+
+- Added `functional_tests/test_workflow_visualization_conversation_mirroring_fix.py`.
+- Updated the latest version-sensitive functional test so its config version assertion stays aligned with `config.py` after this change.
+
+## Impact Analysis
+
+- Workflow conversations now preserve the structured agent citations required to render inline maps and similar visualization payloads.
+- Created conversations now receive the same visualization output instead of only the user seed message, so the rendered artifact appears where the workflow said it created it.
+- Personal and collaborative conversations both follow their existing storage models without introducing a new container or a parallel workflow-specific message format.
+
+## Validation
+
+- Before: the workflow conversation and the created conversation both showed only text such as “Created map visualization.”
+- After: the workflow conversation stores the visualization citation payload, and the created conversation receives a mirrored assistant message that can render the created visualization.

+# Workspace Select-All Initial State Fix
+
+Fixed in version: **0.241.125**
+
+## Issue Description
+
+After entering multi-select mode in personal or group workspace document lists, the header select-all checkbox appeared but could not be clicked until a row checkbox was selected first.
+
+## Root Cause Analysis
+
+- The selection-mode sync calculated visible document checkboxes before applying the selection-mode class and before removing the `d-none` class from row checkboxes.
+- Because the row checkboxes were still hidden during that first calculation, the header select-all checkbox was treated as having no visible document scope and was disabled.
+- Selecting a row triggered a later sync after the row checkboxes were visible, which made the header checkbox start working.
+
+## Technical Details
+
+### Files Modified
+
+- `application/single_app/static/js/workspace/workspace-documents.js`
+- `application/single_app/templates/group_workspaces.html`
+- `application/single_app/config.py`
+- `functional_tests/test_workspace_select_all_initial_state.py`
+- `ui_tests/test_workspace_document_selection_controls.py`
+
+### Code Changes Summary
+
+- Reordered personal workspace selection sync so table/card selection-mode classes and row checkbox visibility are applied before select-all state is calculated.
+- Reordered group workspace selection sync the same way, including folder table and folder-card containers.
+- Added regression coverage for the source ordering and browser-visible enabled state.
+- Updated `config.py` to version `0.241.125` for this fix.
+
+## Validation
+
+### Test Results
+
+- `functional_tests/test_workspace_select_all_initial_state.py` validates the sync ordering and version update.
+- `ui_tests/test_workspace_document_selection_controls.py` now asserts the personal and group header select-all checkbox is visible and enabled immediately after clicking Multi-select.
+
+### User Experience Improvements
+
+- Users can click the header select-all checkbox immediately after enabling multi-select.
+- Personal and group workspace selection behavior now matches the public workspace ordering pattern.

+# Chat Document Dropdown Viewport Fit Fix
+
+Fixed in version: **0.241.009**
+
+## Issue Description
+
+The chat document selector could open downward from the grounded-search controls when the controls were close to the bottom of the browser viewport. On short desktop windows and mobile-influenced layouts, the dropdown extended below the visible screen and made document selection difficult.
+
+## Root Cause Analysis
+
+The shared chat search-filter dropdown sizing helper enforced a minimum dropdown height even when less space was available below the trigger. The document dropdown also had its own viewport adjustment after the dropdown was already shown, so placement was not chosen before Bootstrap/Popper calculated the menu position.
+
+## Version Implemented
+
+Implemented in version: **0.241.009**
+
+The application version was updated in `application/single_app/config.py` from `0.241.008` to `0.241.009`.
+
+## Technical Details
+
+### Files Modified
+
+- `application/single_app/static/js/chat/chat-documents.js`
+- `application/single_app/config.py`
+- `ui_tests/test_chat_document_dropdown_viewport_fit.py`
+
+### Code Changes Summary
+
+- Added viewport-aware dropdown placement for grounded-search dropdowns.
+- Configured Bootstrap/Popper to prefer upward placement when there is not enough room below the trigger.
+- Replaced fixed minimum dropdown heights with available-space clamping.
+- Routed the document selector through the shared dropdown sizing helper instead of maintaining separate post-show sizing logic.
+
+### Testing Approach
+
+- Added a Playwright UI regression test that opens the chat document selector in a short desktop viewport and verifies the dropdown stays inside the visible browser area.
+- The test also verifies that the document list remains internally scrollable when the dropdown is constrained.
+
+## Impact Analysis
+
+The fix is scoped to the chat grounded-search dropdowns for scope, tags, and documents. It does not change document selection state, backend search behavior, or chat message payloads.
+
+## Validation
+
+Before the fix, the document dropdown could extend below the browser viewport when opened near the bottom of the screen. After the fix, the dropdown selects the best available vertical direction and clamps its menu/list height to the viewport.

+# Public Workspace Manage Script Syntax Fix
+
+Fixed/Implemented in version: **0.241.009**
+
+## Issue Description
+
+The public workspace management page could fail to load with a browser syntax error:
+
+```text
+Uncaught SyntaxError: Unexpected token '&' (at manage_public_workspace.js:310:27)
+```
+
+The reported `&bull;` line was valid JavaScript, but the parser reached it after an earlier malformed template-literal fragment in the document-ready event binding block.
+
+## Root Cause Analysis
+
+The `$(document).ready(...)` block in `application/single_app/static/js/public/manage_public_workspace.js` contained duplicated user-search event bindings and spliced fragments from the user-search result template.
+
+Those fragments left raw template markup and HTML table cells inside executable JavaScript, so Chromium and Node reported a syntax error before the rest of the public workspace page scripts could initialize.
+
+## Technical Details
+
+Files modified:

+- `docs/explanation/fixes/v0.241.009/PUBLIC_WORKSPACE_MANAGE_SCRIPT_SYNTAX_FIX.md`
+- `docs/explanation/release_notes.md`
+
+Code changes summary:
+
+- Removed the stray template-literal and HTML fragments from the document-ready handler block.
+- Preserved the delegated `.select-user-btn` click handler added for safe member search selection.
+- Restored the delegated approve and reject request handlers for `#pendingRequestsTable`.
+- Kept the CSV bulk upload handlers immediately after the restored request handlers.
+- Aligned regression artifacts with `VERSION = "0.241.009"` in `application/single_app/config.py`.
+
+Testing approach:
+
+- Added a functional regression that runs `node --check` when Node.js is available and verifies the document-ready block no longer contains the known spliced fragments.
+- Added a Playwright regression that compiles the script with Chromium's JavaScript parser.
+
+Impact analysis:
+
+- Public workspace management pages can initialize again instead of stopping at the first syntax error.
+- Member search selection, pending request approval/rejection, and CSV bulk member upload event wiring remain available.
+
+## Validation
+
+Before the fix, `manage_public_workspace.js` failed to parse and the public workspace page could not load its management scripts. After the fix, both Node.js and Chromium parser checks validate the script, and the restored event handlers are covered by targeted regression tests.

+# SQL ODBC Driver 18 Container Fix - v0.241.009
+
+## Issue Description
+
+Users creating or testing SQL actions against SQL Server or Azure SQL received errors indicating that `ODBC Driver 17 for SQL Server` could not be found. The Python application included `pyodbc`, but the Azure Linux distroless application image did not include the native Microsoft ODBC SQL Server driver and unixODBC runtime files required by `pyodbc`.
+
+## Root Cause Analysis
+
+The SQL action code imported `pyodbc` and built SQL Server connection strings, but the container only installed Python packages from `requirements.txt`. The final distroless runtime image did not copy forward Microsoft ODBC driver files, unixODBC shared libraries, or `/etc/odbcinst.ini`, so `pyodbc.connect()` could fail at runtime with a missing Driver 17 library error.
+
+Existing SQL action defaults also preferred `ODBC Driver 17 for SQL Server`, which meant new actions continued to select the driver users were missing.
+
+## Fixed in version: **0.241.009**
+
+The version was updated in `application/single_app/config.py` from `0.241.008` to `0.241.009` for this fix.
+
+## Technical Details
+
+### Files Modified
+
+| File | Change |
+|------|--------|
+| `application/single_app/Dockerfile` | Registers the Microsoft Azure Linux `ms-non-oss` package feed, installs `msodbcsql18` and `unixODBC` in the builder stage, then copies `/opt/microsoft`, `/etc/odbcinst.ini`, unixODBC shared libraries, and ODBC library paths into the distroless runtime. |
+| `application/single_app/semantic_kernel_plugins/sql_odbc_utils.py` | Adds shared Driver 18 constants, SQL Server connection string construction, and Driver 17-to-18 retry logic for missing-driver errors. |
+| `application/single_app/semantic_kernel_plugins/sql_schema_plugin.py` | Uses Driver 18 as the default SQL Server ODBC driver and applies legacy Driver 17 fallback. |
+| `application/single_app/semantic_kernel_plugins/sql_query_plugin.py` | Uses Driver 18 as the default SQL Server ODBC driver and applies legacy Driver 17 fallback. |
+| `application/single_app/semantic_kernel_plugins/sql_plugin_factory.py` | Generates SQL Server and Azure SQL plugin configuration with Driver 18 defaults. |
+| `application/single_app/route_backend_plugins.py` | Uses Driver 18 defaults and fallback logic in the SQL action Test Connection endpoint. |
+| `application/single_app/templates/_plugin_modal.html` | Presents Driver 18 before Driver 17 in the SQL action driver selector. |
+| `application/single_app/static/js/plugin_modal_stepper.js` | Defaults new SQL actions and examples to Driver 18. |
+| `application/single_app/semantic_kernel_plugins/SQL_Plugins_Configuration_Guide.md` | Updates SQL Server connection string examples to Driver 18. |
+| `functional_tests/test_sql_odbc_driver_18_support.py` | Adds regression coverage for container ODBC runtime installation, Driver 18 defaults, legacy Driver 17 fallback, and version consistency. |
+
+### Code Changes Summary
+
+- The application image now registers the Microsoft Azure Linux `ms-non-oss` package feed, installs the Microsoft ODBC Driver 18 package using `ACCEPT_EULA=Y`, and includes the native ODBC files needed by the final distroless runtime.
+- New SQL Server and Azure SQL action defaults use `ODBC Driver 18 for SQL Server`.
+- Saved actions or connection strings that still reference `ODBC Driver 17 for SQL Server` are retried with Driver 18 when the failure is specifically a missing-driver error.
+- Non-driver errors, such as login failures, are not retried or masked by the fallback logic.
+
+## Testing Approach
+
+- Functional test: `functional_tests/test_sql_odbc_driver_18_support.py`
+- Validates Dockerfile ODBC runtime installation and copy-forward instructions.
+- Validates generated SQL Server connection strings default to Driver 18.
+- Validates saved Driver 17 connection strings retry with Driver 18 when Driver 17 is unavailable.
+- Validates non-driver errors are not hidden by fallback behavior.
+- Validates `config.py` version consistency for v0.241.009.
+
+## Impact Analysis
+
+- **SQL Server and Azure SQL actions**: New actions now target Driver 18 by default, and existing Driver 17 actions can recover automatically when the missing-driver error occurs.
+- **Container deployments**: Azure Linux distroless runtime images include the native ODBC driver and registration files needed by `pyodbc`.
+- **Other database actions**: PostgreSQL, MySQL, and SQLite paths are unchanged.
+- **Security**: The fallback logs driver names and exception type only; it does not log connection strings, usernames, or passwords.
+
+## Validation
+
+Before the fix, SQL actions could fail with missing native ODBC Driver 17 errors despite `pyodbc` being installed. After the fix, the runtime image includes Driver 18, new action defaults point to Driver 18, and legacy Driver 17 references retry with Driver 18 only when the legacy driver is unavailable.

+# Entra Application Graph MFA Auth Fix
+
+Fixed/Implemented in version: **0.241.010**
+
+Related config.py update: `VERSION = "0.241.010"`
+
+## Issue Description
+
+`Initialize-EntraApplication.ps1` could fail when Azure CLI was signed in for normal Azure Resource Manager operations but the cached account still needed a Microsoft Graph MFA or conditional-access challenge before `az ad` commands could run.
+
+## Root Cause Analysis
+
+The script only verified `az account show`, which proves the Azure CLI account is present but does not prove the account can acquire a Microsoft Graph token. When `az ad app list` hit `AADSTS50076` or another interaction-required Graph challenge, the failed output was piped into `ConvertFrom-Json`; the script then continued as if no app registration existed and failed later with a generic create error.
+
+## Technical Details
+
+### Files Modified
+
+- `deployers/Initialize-EntraApplication.ps1`
+- `application/single_app/config.py`
+- `functional_tests/test_entra_application_graph_mfa_auth.py`
+
+### Code Changes Summary
+
+- Added a Microsoft Graph token preflight with `az account get-access-token` after tenant and cloud detection.
+- Added interaction-required detection for MFA, invalid grant, and claims-challenge Azure CLI responses.
+- Added interactive recovery that runs `az login --tenant ... --scope ...` only when Graph access requires it, preserving existing non-MFA cached-token runs.
+- Wrapped app registration and service principal JSON reads in explicit Azure CLI exit-code checks so command failures are not treated as empty JSON.
+
+## Validation
+
+- Functional test: `functional_tests/test_entra_application_graph_mfa_auth.py`
+- PowerShell parser validation for `deployers/Initialize-EntraApplication.ps1`
+- Expected outcome: MFA-gated tenants get a Graph-scoped interactive login prompt before app registration work begins, while non-MFA tenants continue through the existing authenticated Azure CLI workflow without an extra login.

+# Entra Application AZD Environment Persistence Fix
+
+Fixed/Implemented in version: **0.241.011**
+
+Related config.py update: `VERSION = "0.241.011"`
+
+## Issue Description
+
+After running `Initialize-EntraApplication.ps1`, users had to copy the app registration client ID, client secret, and service principal ID into a separate text file and paste them back into `azd up` prompts later.
+
+## Root Cause Analysis
+
+The Entra registration script created the values needed by `deployers/bicep/main.parameters.json`, but it only printed them to the terminal. It did not persist those values through `azd env set`, so the AZD environment could not supply `ENTERPRISE_APP_CLIENT_ID`, `ENTERPRISE_APP_CLIENT_SECRET`, or `ENTERPRISE_APP_SERVICE_PRINCIPAL_ID` automatically during provisioning.

+
+### Code Changes Summary
+
+- Added `-AzdEnvironmentName` to explicitly choose the target AZD environment.
+- Added `-SkipAzdEnvironmentUpdate` for standalone/manual app registration workflows.
+- Added AZD environment resolution using `AZURE_ENV_NAME`, `.azure/config.json` `defaultEnvironment`, and then the deployment `Environment` value.
+- Persisted app registration outputs with `azd env set --environment ...` after the client secret is generated.
+- Kept persistence failures non-fatal so successful app registration creation still completes and prints manual recovery guidance.

+# SQL ODBC Driver Registration File Fix
+
+Fixed/Implemented in version: **0.241.012**
+
+Related config.py update: `VERSION = "0.241.012"`
+
+## Issue Description
+
+`azd up` could fail during the Windows `predeploy` ACR build after installing SQL Server ODBC Driver 18. The Docker build reached the distroless runtime stage and then failed with missing ODBC runtime copy sources, including:
+
+```text
+COPY failed: stat etc/odbcinst.ini: file does not exist
+COPY failed: no source files were specified
+```
+
+## Root Cause Analysis
+
+The Dockerfile assumed the Azure Linux `msodbcsql18` and `unixODBC` package installation would always create `/etc/odbcinst.ini` in the builder stage and place unixODBC libraries under `/usr/lib64`. In the ACR remote build, `/etc/odbcinst.ini` was absent and the unixODBC libraries were not available through the hardcoded `/usr/lib64/libodbc*` copy pattern, so Docker failed before the image could be published.

+- `functional_tests/test_entra_application_azd_env_persistence.py`
+
+### Code Changes Summary
+
+- After installing `msodbcsql18`, the Docker builder stage now resolves the installed `libmsodbcsql-*.so*` path under `/opt/microsoft/msodbcsql18/lib64`.
+- The builder writes a deterministic `/etc/odbcinst.ini` registration for `ODBC Driver 18 for SQL Server`.
+- The builder stages unixODBC and libltdl shared libraries from either `/usr/lib64` or `/usr/lib` into `/odbc-runtime/usr/lib64`.
+- The distroless runtime can now copy the registration file and staged unixODBC libraries reliably while preserving the existing Driver 18 runtime support.
+
+## Validation
+
+- ACR log review for failed run `cp1` confirmed the missing `/etc/odbcinst.ini` source file.
+- ACR log review for failed run `cp2` confirmed the hardcoded `/usr/lib64/libodbc*` copy pattern had no sources.
+- ACR verification run `cp3` succeeded with the staged ODBC runtime files.
+- `azd deploy` completed successfully after the Dockerfile fix.

+# Chat Conversation Info Icon Button Fix - Version 0.241.016
+
+Fixed in version: **0.241.016**
+
+## Issue Description
+
+The conversation details button in the chat header displayed as a dark outlined circular button. This made the info affordance stand out more than intended.
+
+## Root Cause Analysis
+
+The button used Bootstrap's `btn-outline-secondary` class together with the chat icon button shape, creating a visible bordered circle around the `bi-info-circle` icon.

+The chat header now shows only the info icon for conversation details while retaining tooltip, click behavior, and accessible keyboard focus.
+
+## Validation
+
+Before: the info button showed a visually prominent outlined circular border.
+
+After: the info button renders as a quiet icon-only action with no persistent border or background.

+## Testing Approach
+
+- Python syntax checks for edited Python files.
+- Focused UI test collection for chat sidebar toggle coverage.
+- CSS/template diagnostics for edited files.
+
+## Impact Analysis
+
+Compact sidebar controls now align with the left edge and visual scale of the normal sidebar nav icons, while the large sidebar toggle remains unchanged.
+
+## Validation
+
+Before: compact collapse icon occupied a larger invisible control box and visually sat off the sidebar icon grid.
+
+After: compact collapse icon uses the same visual size and left alignment as other sidebar navigation icons.

+# Per-Message Email Chart PNG Export Fix
+
+Fixed/Implemented in version: **0.241.019**
+
+## Issue Description
+
+Per-message "Open in Email" drafts did not use the existing inline chart export path. Messages containing SimpleChat chart blocks could leave the email workflow with text placeholders or raw chart markdown instead of chart PNG output, even though Word and PowerPoint exports already rendered those charts as images.
+
+## Root Cause Analysis
+
+The Word and PowerPoint export paths called `replace_inline_chart_blocks_with_export_html()` before rendering documents. The email draft path rendered markdown directly into plain text for `mailto:`, so it skipped the server-side chart-to-PNG conversion helper.
+
+Because `mailto:` cannot attach files automatically, the email workflow also needed a separate attachment payload and frontend download step for the generated PNGs.
+
+## Technical Details
+
+### Files Modified
+
+- `application/single_app/route_backend_conversation_export.py`
+- `application/single_app/static/js/chat/chat-message-export.js`
+- `application/single_app/config.py`
+- `functional_tests/test_per_message_export.py`
+- `ui_tests/test_chat_message_email_chart_download.py`
+- `docs/explanation/features/v0.241.001/MESSAGE_EXPORT.md`
+
+### Code Changes Summary
+
+- Reused the existing inline chart export helper in `_message_to_email_draft_payload()` before plain-text email rendering.
+- Extracted converted chart images into an `attachments` payload with PNG data URIs, filenames, captions, and content types.
+- Replaced chart image positions in the mailto body with filename references, avoiding raw `simplechart` markdown and oversized base64 text in the email body.
+- Updated the frontend email action to download chart PNG files before opening the user's default mail client.
+- Bumped the application version to `0.241.019`.
+
+### Testing Approach
+
+- Extended `functional_tests/test_per_message_export.py` with a regression check that injects a converted inline chart and verifies the email draft payload includes a PNG attachment.
+- Updated frontend source assertions to confirm the email workflow consumes draft attachments.
+- Added a Playwright UI regression that stubs the email draft response and verifies the browser downloads the PNG payload before composing the mailto draft.
+
+## Validation
+
+### Before
+
+- Open in Email skipped the chart-to-PNG conversion used by Word and PowerPoint exports.
+- Chart blocks could remain as text-only content in the email draft flow.
+
+### After
+
+- Open in Email converts inline chart blocks to PNG data through the shared export helper.
+- The generated mailto body references chart PNG filenames where charts appear.
+- The frontend downloads chart PNG files before opening the email draft so users can attach them.
+
+### User Experience Improvement
+
+Users opening a chart-bearing chat message in email now receive the chart PNG files alongside the prefilled draft, matching the image-export behavior of Word and PowerPoint as closely as `mailto:` allows.

+# Approvals API Load Fix
+
+Fixed/Implemented in version: **0.241.021**
+
+## Issue Description
+
+The approvals page could fail to load the pending approval queue because `/api/approvals?page=1&page_size=20&status=pending` returned HTTP 500. When this happened, the browser rendered `Error loading approvals` and users could not review or act on pending approval requests from `/approvals`.
+
+## Root Cause Analysis
+
+The approvals list helper queried the cross-partition approvals container with `ORDER BY c.created_at DESC`. That made the page dependent on Cosmos DB order-by query support and indexing behavior even though the helper already loaded the matching approvals into memory before applying authorization filtering and pagination.
+
+Legacy or partially migrated approval records could also carry unexpected shapes such as `metadata: null`, and direct role checks could receive a missing or scalar roles value. Those shapes could raise Python exceptions during eligibility checks and convert one bad approval record into a full API failure.
+
+## Technical Details
+
+### Files Modified
+
+- `application/single_app/functions_approvals.py`
+- `functional_tests/test_approvals_api_load_fix.py`
+- `docs/explanation/fixes/v0.241.021/APPROVALS_API_LOAD_FIX.md`
+- `application/single_app/config.py` tracks the current fix version `0.241.021`
+
+### Code Changes Summary
+
+- Removed the Cosmos SQL `ORDER BY` clause from the approvals list query.
+- Added local sorting by `created_at` after the cross-partition query returns matching approval records.
+- Added normalization helpers for user role lists and approval metadata dictionaries.
+- Hardened approval visibility and approval-right checks so missing roles or `metadata: null` do not crash the API.
+- Added per-record eligibility error handling so one malformed approval is skipped and logged instead of failing the full approvals list response.
+
+## Testing Approach
+
+- Added `functional_tests/test_approvals_api_load_fix.py` with an in-memory Cosmos-like approvals container.
+- Verified the approvals query does not emit `ORDER BY` while still returning newest approvals first.
+- Verified authorization helpers tolerate missing roles and legacy `metadata: null` approval records.
+- Verified this fix document and the current config version are present.
+
+## Validation
+
+### Before
+
+- `/api/approvals` could return 500 when the cross-partition order-by query failed.
+- A single malformed legacy approval record could stop the entire approvals page from loading.
+
+### After
+
+- `/api/approvals` can load pending approvals without relying on Cosmos DB order-by support.
+- Legacy approval metadata and missing role values are normalized before authorization checks.
+- Malformed individual approvals are skipped with logging while the rest of the page remains usable.
+
+### User Experience Improvement
+
+Approval reviewers can open `/approvals` and load the pending queue reliably, even when older approval documents exist in the container.

+# Markdown Citation Lookup Fix
+
+Fixed/Implemented in version: **0.241.021**
+
+## Issue Description
+
+Opening citations for Markdown and other text-derived documents could show a toast such as `Error fetching citation: Server responded with status 404`. The chat message still displayed the citation, but `/api/get_citation` could not always find the underlying AI Search chunk when the rendered citation id was stale, incomplete, or reconstructed from older stored citation metadata.
+
+## Root Cause Analysis
+
+The citation route only attempted an exact AI Search key lookup using the browser-supplied `citation_id`. Markdown chunks are indexed as document-scoped chunk keys such as `<document_id>_<chunk_number>`, but some stored or fallback-rendered citation buttons could supply only a chunk-derived id. Once the exact key lookup failed, the route moved through the workspace indexes and returned 404 without trying the document and chunk context already present in the citation metadata.
+
+Enhanced citation fallback made the issue more visible for `.md` files because Markdown is not opened in the enhanced PDF/image/audio/video viewers. The browser fell back to text citation retrieval, but that fallback did not preserve document and page context.
+
+## Technical Details
+
+### Files Modified
+
+- `application/single_app/route_backend_documents.py`
+- `application/single_app/static/js/chat/chat-citations.js`
+- `application/single_app/static/js/chat/chat-enhanced-citations.js`

+- `application/single_app/config.py`
+- `functional_tests/test_markdown_citation_lookup_fallback.py`
+- `ui_tests/test_chat_markdown_citation_lookup_payload.py`
+
+### Code Changes Summary
+
+- Added citation lookup helpers that try exact keys first, then rebuild document-scoped chunk keys from `document_id`, `page_number`, and `chunk_id`.
+- Added a final metadata query fallback for legacy chunks whose indexed key does not match the current `<document_id>_<chunk>` pattern.
+- Kept the existing document access check in place after chunk resolution so recovered chunks still require authorized document visibility.
+- Updated citation buttons to carry `data-document-id`, `data-page-number`, and `data-chunk-id` attributes.
+- Updated text citation fetches and enhanced-citation fallbacks to send the extra lookup context to `/api/get_citation`.
+- Bumped the application version to `0.241.021`.
+
+## Testing Approach
+
+- Added a functional regression test that loads the citation helper functions, simulates missing exact keys, and verifies markdown chunks are recovered by reconstructed key and metadata query fallback.
+- Added source-level assertions that browser citation code sends document/page/chunk context through text and enhanced fallback paths.
+- Added a Playwright UI regression that renders a markdown citation button without a stored `citation_id`, clicks it, and verifies the `/api/get_citation` payload includes the recovered document-scoped citation id plus lookup context.
+
+## Validation
+
+### Before
+
+- `/api/get_citation` returned 404 as soon as exact key lookup failed across personal, group, and public indexes.
+- Markdown enhanced-citation fallback could call text citation lookup without the document context needed to recover the chunk.
+
+### After
+
+- Exact citation IDs continue to work as before.
+- Markdown/text citation buttons can recover the indexed chunk from document, page, and chunk metadata.
+- Unauthorized or inaccessible documents still return access errors instead of exposing chunk text.
+
+### User Experience Improvement
+
+Users can open citations for Markdown files without the red 404 toast when the chat already has enough stored citation metadata to identify the source chunk.

+# Generated Analysis Markdown Preview Fix
+
+Fixed/Implemented in version: **0.241.022**
+
+## Issue Description
+
+Generated analysis artifacts saved as Markdown displayed their chat-card preview as raw source text. Headings, bold spans, and other Markdown syntax were visible in the preview instead of rendering like the rest of the chat response.
+
+## Root Cause Analysis
+
+The generated artifact card reused the plain text preview block for every non-tabular preview. That was appropriate for JSON fallback content, but Markdown artifacts are tagged with `output_format: md` and need the same explicit Markdown rendering and sanitization boundary used by assistant message content.
+
+## Technical Details
+
+Files modified:
+
+- `application/single_app/static/js/chat/chat-messages.js`
+- `application/single_app/static/css/chats.css`
+- `ui_tests/test_chat_generated_tabular_output_card.py`
+- `application/single_app/config.py`
+
+Code changes summary:
+
+- Detect generated artifacts with `md` or `markdown` output formats, including `.md` and `.markdown` file names.
+- Render Markdown previews with `marked.parse(...)` and `DOMPurify.sanitize(...)` before assigning the sanitized HTML to the preview container.
+- Keep JSON and other plain-text fallback previews in the existing preformatted text block.
+- Add compact Markdown-preview styling so rendered headings, lists, tables, and code blocks fit inside the artifact card.
+
+## Testing Approach
+
+Added UI regression coverage in `ui_tests/test_chat_generated_tabular_output_card.py` that injects a generated Markdown artifact into the chat UI, verifies bold text and headings render as HTML, and confirms unsafe event-handler attributes do not survive sanitization.
+
+## Impact Analysis
+
+Markdown artifact previews now match user expectations while preserving the existing raw-text behavior for JSON and other non-Markdown preview formats. The sanitizer boundary prevents generated or uploaded Markdown from becoming executable browser content.
+
+## Validation
+
+Before the fix, previews showed raw syntax such as `**Document-level summary**` and `## Core framework`. After the fix, those preview lines render as styled Markdown inside the card, with raw Markdown markers removed from the visible preview.
+
+Related config.py version update: `VERSION = "0.241.022"`.

+# Chat Prompt Desktop Toolbar Position Fix
+
+Fixed/Implemented in version: **0.241.025**
+
+## Issue Description
+
+The prompt selector dropdown appeared in the chat toolbar controls row on larger desktop canvases.
+
+That placed prompts after the model or agent selector and separated them from the modifier buttons, even though the intended large-canvas order is prompt selector, model or agent selector, then modifier controls.
+
+## Root Cause Analysis
+
+The desktop prompt slot was anchored in `chat-toolbar-controls`, the same row that now exists primarily for the mobile tools toggle.
+
+The mobile toolbar work correctly introduced movable desktop and mobile selector surfaces, but the desktop anchor for prompts still lived outside the main desktop tools surface. That made the desktop order depend on the controls row instead of the larger toolbar canvas.
+
+## Technical Details
+
+Files modified: `application/single_app/config.py`, `application/single_app/templates/chats.html`, `application/single_app/static/css/chats.css`, `functional_tests/test_chat_prompt_desktop_toolbar_position.py`, `ui_tests/test_chat_prompt_desktop_toolbar_position.py`
+
+Code changes summary:
+
+- Moved the desktop prompt selector slot into the main desktop tools surface before the model or agent selector.
+- Kept the model or agent selector in the same desktop tools surface directly before the modifier buttons.
+- Made `.chat-toolbar-controls` desktop-hidden so it remains reserved for the mobile tools toggle instead of hosting desktop selectors.
+- Preserved the mobile selector slots so prompt, model, and agent selectors still move into the mobile tools drawer.
+- Added functional and Playwright UI coverage for the desktop selector order.
+
+Impact analysis:
+
+- Desktop prompt selection now appears to the left of the model or agent selector and modifier buttons.
+- The mobile drawer behavior from the previous toolbar work remains intact.
+- The toolbar DOM now matches the intended desktop and mobile ownership split more clearly.
+
+## Validation
+
+Test coverage: `functional_tests/test_chat_prompt_desktop_toolbar_position.py`, `ui_tests/test_chat_prompt_desktop_toolbar_position.py`
+
+Test results:
+
+- `functional_tests/test_chat_prompt_desktop_toolbar_position.py`: passed standalone and under pytest.
+- `ui_tests/test_chat_prompt_desktop_toolbar_position.py`: added to validate rendered desktop order; skipped in the current environment because authenticated UI test settings are not configured.
+
+Before/after comparison:
+
+- Before: The prompt selector could render in `.chat-toolbar-controls` after the model or agent selector on larger desktop canvases.
+- After: The prompt selector renders in the desktop tools surface before the model or agent selector and before modifier controls, while mobile still uses the drawer slots.

+# Approvals Route Authorization Helper Fix
+
+Fixed/Implemented in version: **0.241.027**
+
+## Issue Description
+
+The approvals page could return HTTP 500 with `NameError: name '_can_user_approve' is not defined` when loading approval requests. This affected users who should have been able to see targeted document deletion approvals, including the requesting admin and the user whose files were queued for deletion.
+
+## Root Cause Analysis
+
+`route_backend_control_center.py` imported approval helpers with `from functions_approvals import *`, but Python star imports intentionally skip names that start with an underscore unless a module defines `__all__`. The route already used `_can_user_approve` to calculate each approval row's `can_approve` flag, so the authorization helper was unavailable at runtime even though the helper existed in `functions_approvals.py`.
+
+## Technical Details
+
+### Files Modified
+
+- `application/single_app/route_backend_control_center.py`
+- `application/single_app/config.py`
+- `functional_tests/test_approvals_route_helper_import.py`
+- `docs/explanation/fixes/v0.241.027/APPROVALS_ROUTE_AUTHORIZATION_HELPER_FIX.md`
+
+### Code Changes Summary
+
+- Explicitly imported `_can_user_approve` in the Control Center backend route module.
+- Reused `_can_user_approve` for the admin approval list `can_approve` calculation so list responses match the same authorization helper used by detail and action endpoints.
+- Updated `application/single_app/config.py` to version `0.241.027` for this fix.
+
+### Testing Approach
+
+- Added `functional_tests/test_approvals_route_helper_import.py` to verify the route explicitly imports the underscore authorization helper.
+- Validated targeted document deletion approval boundaries: the requesting admin and target user can view and approve, while an unrelated non-admin user cannot view or approve.
+- Verified the fix document references the functional test and current config version.
+
+## Validation
+
+### Before
+
+- `/api/approvals` could fail during row decoration with a `NameError` even after `get_pending_approvals()` had already applied eligibility filtering.
+- The admin approval list used a separate requester-based `can_approve` rule that could diverge from the route authorization helper.
+
+### After
+
+- Approval list and detail routes can calculate `can_approve` without crashing.
+- Approval visibility and approval rights continue to use the existing centralized authorization helper.
+- Unrelated users remain blocked from targeted approval records.

+# Sidebar Menu State Save Fix
+
+Fixed in version: **0.241.027**
+
+## Issue Description
+
+Collapsing the left sidebar sections could fail with `POST /api/user/settings` returning `400 BAD REQUEST`. When that happened, the menu appeared to collapse for the current page only, then reset back to the default expanded state after navigation.
+
+The issue affected persisted menu state for Workspaces, Support, custom external-link menus such as renamed link groups, Admin Settings, Control Center, and Conversations.
+
+## Root Cause Analysis
+
+The settings endpoint required every `sidebarMenuState` entry to use one of the known menu keys and an exact boolean value. If a saved or client-side state object contained a stale key, a string value such as `"false"`, or any other invalid value, the endpoint rejected the entire update instead of saving the valid menu state.
+
+## Technical Details
+
+### Files Modified
+
+*   `application/single_app/static/js/sidebar.js`
+*   `application/single_app/route_backend_users.py`
+*   `application/single_app/config.py`
+*   `ui_tests/test_sidebar_menu_state_preference.py`
+*   `docs/explanation/release_notes.md`
+
+### Code Changes Summary
+
+*   Added client-side normalization so the browser only saves supported sidebar menu keys with boolean values.
+*   Added backend normalization so stale keys are ignored and string booleans are converted instead of causing a `400 BAD REQUEST`.
+*   Preserved the existing per-user settings storage path by continuing to save state under `sidebarMenuState`.
+*   Updated `config.py` from `0.241.026` to `0.241.027` for this fix.
+
+### Testing Approach
+
+*   Expanded `ui_tests/test_sidebar_menu_state_preference.py` to seed legacy invalid menu state, verify the settings API accepts and sanitizes it, then confirm collapsed and expanded state survives page navigation.
+*   Ran JavaScript parse checks for the touched sidebar scripts.
+*   Ran Python compile checks for the touched backend route, config, and UI test.
+
+## Impact Analysis
+
+The fix is limited to sidebar menu display preferences. It does not change authorization, menu visibility rules, or the configured destinations shown inside each menu.
+
+## Validation
+
+### Before
+
+Collapsing a sidebar menu could send a `sidebarMenuState` update that included stale or invalid values, causing `/api/user/settings` to reject the save with `400 BAD REQUEST`.
+
+### After
+
+Sidebar menu state is normalized before saving and again at the API boundary. Valid menu state persists across page navigation, while stale or invalid values are dropped safely.
+
+### User Experience Improvements
+
+Users can collapse or expand sidebar sections and keep that layout as they move around the app, including for Workspaces, Support, and custom-named external link menus.

+# Control Center Debug Print Import Fix (v0.241.029)
+
+Fixed/Implemented in version: **0.241.029**
+
+## Issue Description
+
+Application startup failed while importing the admin settings route because `functions_control_center.py` attempted to import `debug_print` from `config.py`.
+
+The runtime error was:
+
+```text
+ImportError: cannot import name 'debug_print' from 'config'
+```
+
+## Root Cause Analysis
+
+`debug_print` is exposed through the shared `functions_debug.py` compatibility shim, which forwards to the Application Insights logging implementation. Most backend modules already import `debug_print` from that shim.
+
+The Control Center helper module was the lone startup path importing `debug_print` from `config.py`, where that symbol is not defined.
+
+## Technical Details
+
+Files modified: `application/single_app/functions_control_center.py`, `application/single_app/config.py`, `functional_tests/test_control_center_debug_print_import.py`
+
+Code changes summary:
+
+- Updated `functions_control_center.py` to import Cosmos containers from `config.py` and `debug_print` from `functions_debug.py`.
+- Bumped `application/single_app/config.py` to `VERSION = "0.241.029"`.
+- Added a source-level functional regression test that prevents `functions_control_center.py` from importing `debug_print` from `config.py` again.
+
+Impact analysis:
+
+- Admin settings and Control Center helper imports no longer fail during application startup.
+- Debug logging continues to flow through the existing Application Insights-backed debug shim.
+- No authorization, route behavior, or frontend rendering behavior changed.
+
+## Validation
+
+Test coverage: `functional_tests/test_control_center_debug_print_import.py`
+
+Test results:
+
+- `python -m py_compile application/single_app/config.py application/single_app/functions_control_center.py functional_tests/test_control_center_debug_print_import.py`

+- `python -c "import route_frontend_admin_settings; print('route_frontend_admin_settings import ok')"`
+
+Before/after comparison:

+- Before: Startup failed while loading `route_frontend_admin_settings.py` because `config.py` did not export `debug_print`.
+- After: `functions_control_center.py` resolves `debug_print` through the established `functions_debug.py` shim and the admin settings import completes.

+# Profile Workspace Tabs JSON Default Fix
+
+## Header Information
+
+Issue description: Opening `/profile` could return HTTP 500 when the Profile template attempted to serialize an undefined workspace permission variable into `window.profilePageConfig`.
+
+Root cause analysis: The Profile route normally passes `can_create_groups` and `can_create_public_workspaces`, but Jinja `tojson` cannot serialize an `Undefined` value. If the template was rendered without those variables, such as during a reload mismatch or alternate render path, the page failed before any frontend JavaScript could run.
+
+Version implemented: **0.241.029**
+
+Fixed/Implemented in version: **0.241.029**
+
+## Technical Details
+
+Files modified:
+
+- `application/single_app/templates/profile.html`
+- `functional_tests/test_profile_workspace_tabs.py`
+- `ui_tests/test_profile_workspace_tabs.py`
+- `application/single_app/config.py`
+
+Code changes summary:
+
+- Added Jinja `default(false)` safeguards before JSON serialization of profile workspace create-permission flags.
+- Added default safeguards for the related profile page config feature flags.
+- Extended the profile workspace tab functional test to assert the defaulted `tojson` contract remains in place.
+
+Testing approach:
+
+- Run JavaScript syntax validation for the profile tab script.
+- Compile the modified Python route and tests.
+- Run the focused profile workspace functional regression test.
+- Run diff whitespace validation.
+
+Impact analysis:
+
+Users can open the Profile page even if workspace permission values are missing from the render context. The profile tabs still receive concrete booleans in normal route execution, and the template fallback prevents a server-side 500.
+
+## Validation
+
+Test results:
+

+# Approval Requester Action Boundary Fix
+
+Fixed/Implemented in version: **0.241.030**
+
+## Issue Description
+
+Approval request submitters could see an `Approve & Execute` action for requests they created. Submitters should be able to view their own pending approval requests and deny them to cancel the request, but they must not be able to approve and execute their own request.
+
+## Root Cause Analysis
+
+The approval authorization helper treated the requester as eligible to approve in some cases. The approval list also used approval eligibility as the pending visibility check, and the modal used a single `can_approve` flag to show both approve and deny actions. That combined view, approve, and deny into one authorization concept.
+
+## Technical Details
+
+### Files Modified
+
+- `application/single_app/functions_approvals.py`
+- `application/single_app/route_backend_control_center.py`
+- `application/single_app/route_backend_safety.py`

+- `functional_tests/test_approvals_route_helper_import.py`
+- `functional_tests/test_safety_violation_remediation_approvals.py`
+- `ui_tests/test_approvals_requester_action_buttons.py`
+
+### Code Changes Summary
+
+- Split approval and denial authorization by adding a denial-specific check.
+- Blocked requesters from approving their own requests in both route authorization and direct approval execution.
+- Allowed requesters to deny their own pending requests while preserving view access.
+- Added `can_deny` to approval API responses so the browser can show Deny without showing Approve.
+- Stopped safety remediation from auto-approving an approval request created by the same actor.
+- Updated `application/single_app/config.py` to version `0.241.030` for this fix.
+
+### Testing Approach
+
+- Updated `functional_tests/test_approvals_route_helper_import.py` to validate requester view/deny access, approval denial, route markers, and direct approval execution rejection.
+- Updated `functional_tests/test_safety_violation_remediation_approvals.py` to validate safety requesters cannot approve their own requests even with the required review role.
+- Added `ui_tests/test_approvals_requester_action_buttons.py` to validate the approvals modal hides `Approve & Execute` while showing `Deny Request` for requester-owned pending approvals.
+
+## Validation
+
+### Before
+
+- Requesters could be treated as eligible approvers for their own approval requests.
+- The modal used `can_approve` to show both approval and denial actions.
+- Safety remediation could auto-approve a request created by the same actor.
+
+### After
+
+- Requesters can view and deny their own pending approval requests.
+- Requesters cannot approve or execute their own approval requests.
+- Other eligible reviewers can still approve or deny requests they did not submit.
+- Unrelated users remain blocked by the existing approval visibility checks.

+# Chat Document Picker Width Fix
+
+Fixed/Implemented in version: **0.241.030**
+
+## Issue Description
+
+The chat Document dropdown used a short field width in Search and Analyze mode on larger canvases, while Compare showed the desired full-width picker.
+
+Users expected Search, Analyze, and Compare to share the same spacious desktop picker layout without losing the stacked full-width mobile behavior.
+
+## Root Cause Analysis
+
+The comparison modal had dedicated CSS that forced picker fields, dropdowns, and selects to `width: 100%`.
+
+The normal Search and Analyze picker row did not share those rules, so the Document field could sit at its minimum width instead of growing across the remaining toolbar row. The dropdown sizing JavaScript then matched that smaller field width.
+
+## Technical Details
+
+Files modified: `application/single_app/config.py`, `application/single_app/static/css/chats.css`, `functional_tests/test_chat_document_picker_full_width.py`, `functional_tests/test_chat_prompt_desktop_toolbar_position.py`, `ui_tests/test_chat_document_action_selector_labels.py`, `ui_tests/test_chat_prompt_desktop_toolbar_position.py`
+
+Code changes summary:
+
+- Added shared full-width dropdown and form-select rules for chat search panel fields.
+- Gave the wide Document field a larger flexible basis and removed its desktop maximum width cap.
+- Kept the existing mobile rules that make all document picker fields stack at full width.
+- Added functional coverage for the CSS and template contract.
+- Extended the Playwright document action test to verify Search, Analyze, and Compare all stretch the Document picker across the desktop row.
+
+Impact analysis:
+
+- Search, Analyze, and Compare now use consistent full-width Document picker behavior on larger screens.
+- Mobile remains a single-column, full-width picker layout.
+- The dropdown menu continues to size from the field container through existing picker JavaScript.
+
+## Validation
+
+Test coverage: `functional_tests/test_chat_document_picker_full_width.py`, `ui_tests/test_chat_document_action_selector_labels.py`
+
+Test results:
+
+- `functional_tests/test_chat_document_picker_full_width.py`: validates the static template and CSS contract for the full-width document picker.
+- `ui_tests/test_chat_document_action_selector_labels.py`: validates rendered desktop picker widths for Search, Analyze, and Compare; skips when authenticated UI test settings are not configured.
+
+Before/after comparison:
+
+- Before: Search and Analyze could render a narrow Document dropdown while Compare appeared full width.
+- After: All three document actions share the full-width desktop Document picker and retain the mobile stacked layout.

+# Chat Search Dropdown Menu Width Fix
+
+Fixed/Implemented in version: **0.241.031**
+
+## Issue Description
+
+The grounded-search filter strip kept the opened Scope, Tags, and Document dropdown menus the same width as their compact closed controls. This made workspace names, tags, and document titles difficult to read, especially in full-canvas and constrained canvas views. The document search field also appeared ineffective because filtered document rows were still forced visible by CSS.
+
+## Root Cause Analysis
+
+The dropdown sizing helper measured the closed filter field and applied that width directly to the opened menu. At the same time, document dropdown rows used a high-specificity `display: block !important` rule that overrode the searchable dropdown helper's `.d-none` hidden state.
+
+## Technical Details
+
+Files modified:
+- `application/single_app/static/css/chats.css`
+- `application/single_app/static/js/chat/chat-documents.js`
+- `application/single_app/templates/chats.html`
+- `application/single_app/config.py`
+- `ui_tests/test_chat_search_panel_document_row_layout.py`
+
+Code changes summary:
+- Made the closed Action and Scope controls more compact in the desktop filter grid while preserving a flexible Document column.
+- Gave Scope, Tags, and Document menus independent preferred open widths with viewport-aware caps.
+- Capped opened menu height so long lists scroll after roughly ten visible items instead of extending far up the canvas.
+- Removed inline width and height styles from the chat filter markup so CSS and the dropdown sizing helper own layout behavior.
+- Restored document search filtering by allowing `.d-none` to hide document rows.
+- Updated `config.py` from version `0.241.030` to `0.241.031`.
+
+## Validation
+
+Testing approach:
+- Extended the Playwright UI regression to confirm Search and Analyze still keep the Document picker on the desktop row.
+- Added assertions that open Scope and Tags menus are wider than their closed controls, Document menu remains readable, and all opened menus have capped scrollable item regions.
+- Added an assertion that a document row hidden by search resolves to `display: none`.
+- Preserved mobile validation that the filter controls stack without horizontal overflow.
+
+Expected behavior after the fix:
+- Closed controls stay compact in full-canvas layouts.
+- Opened workspace, tag, and document menus are wider and easier to scan.
+- Long menus scroll within a capped height.
+- Document search hides non-matching document rows correctly.

+# PowerPoint Structured Markdown Export Fix
+
+## Header Information
+
+Fixed in version: **0.241.031**
+
+Enhanced in version: **0.241.032**
+
+Issue description:
+
+PowerPoint export could summarize an assistant message that already contained a complete slide-by-slide markdown deck. A 32-slide markdown answer could be passed back through AI slide planning and reduced to a much smaller deck.
+
+Root cause analysis:
+
+The export path always asked the model to create a fresh PowerPoint outline for non-empty content. That prompt limited output to a small slide range, and the fallback/sanitization path also applied a hard slide cap, so already structured slide markdown was treated like unstructured prose.
+
+Related config update: `application/single_app/config.py` now sets `VERSION = "0.241.032"` after the follow-up rendering improvements.
+
+## Technical Details
+
+Files modified:
+
+- `application/single_app/route_backend_conversation_export.py`
+- `application/single_app/config.py`
+- `functional_tests/test_per_message_powerpoint_export.py`
+
+Code changes summary:
+
+- Added deterministic detection for markdown decks that use numbered slide headings or slide separators.
+- Bypassed AI slide planning for structured decks so the exported `.pptx` keeps the source slide count and slide titles.
+- Suppressed generated title, appendix, and reference slides for structured decks so authored slide counts stay exact.
+- Added follow-up rendering support for authored title slides, native markdown tables, authored slide-number footers, and trimming of non-slide speaker-note/caveat text.
+- Changed the seven-slide cap into the default for unstructured content, with a bounded optional `slide_count` request value for future UI/API customization.
+- Kept AI planning for unstructured messages while letting the caller request a larger target deck size up to the supported limit.
+
+Testing approach:
+
+- Updated the per-message PowerPoint functional test to generate a 32-slide markdown deck with citations and verify the exported PowerPoint contains exactly 32 slides.
+- Added validation coverage for accepted and rejected optional `slide_count` values.
+- Retained existing coverage for route registration, frontend hook presence, message-model selection, and appendix rendering.
+
+## Validation
+
+Before:
+
+- A slide-structured assistant response could be replanned into a shorter presentation.
+- The model prompt and sanitizer imposed small slide-count limits even when the source already specified each slide.
+
+After:
+
+- Structured markdown exports directly to PowerPoint without AI summarization.
+- A 32-slide markdown deck exports as 32 PowerPoint slides.
+- Unstructured message export still defaults to a concise deck, while `slide_count` can request a specific bounded target.

+# Profile Workspace Tab Deep Link and Card Interaction Fix
+
+## Header Information
+
+Issue description: The Profile-hosted My Groups and My Public Workspaces tabs could miss create buttons for eligible users when permission values were absent from the render context. Sidebar account links to those tabs could land on Profile without selecting the requested tab. Workspace cards also lacked the same hover and click affordance used by agent and action cards.
+
+Root cause analysis: The Profile template depended directly on route-provided permission booleans for create buttons. The server-rendered active tab also depended on route-side tab normalization, so any settings mismatch could leave Stats selected even when the URL contained `?tab=groups` or `?tab=public-workspaces`. Workspace cards were rendered as passive containers with only explicit Manage buttons.

+- Added Profile template fallback permission variables based on `app_settings` and current session roles, while still honoring route-provided values when present.
+- Updated the create button and modal guards to use the resolved Profile permission variables.
+- Added client-side Profile tab activation from the URL query string when the requested tab exists.
+- Added card hover/focus styling and click-to-manage behavior for group and public workspace cards.
+- Extended the static functional regression test for the permission fallback, deep-link activation, and card navigation contracts.
+
+Testing approach:
+
+- JavaScript syntax check for `profile-tabs.js`.
+- Python compile checks for modified Python files and tests.
+- Focused functional regression test for the Profile workspace tabs.
+- UI test entrypoint for browser behavior, with clean skip when authenticated Playwright state is not configured.
+- Git whitespace validation.
+
+Impact analysis:
+
+Eligible users now see Create Group and Create Public Workspace controls even if the route context is missing those booleans. Sidebar links reliably select the intended Profile tab. Card view is more discoverable and faster to use because clicking the card opens the corresponding manage page.

+# Chat Document Search Bulk Selection Fix
+
+Fixed/Implemented in version: **0.241.032**
+
+## Issue Description
+
+When users typed in the Document dropdown search box and then used the top bulk action, the picker still selected every available document instead of only the documents visible in the filtered search results. This made Search, Analyze, and Compare workflows select a much broader document set than the user intended.
+
+## Root Cause Analysis
+
+The document bulk action calculated selection from the hidden `document-select` options. That hidden select knows which documents are available for the current scope and tag filters, but it does not know which dropdown rows are currently hidden by the document search text.
+
+## Technical Details
+
+Files modified:
+- `application/single_app/static/js/chat/chat-documents.js`
+- `application/single_app/static/js/chat/chat-searchable-select.js`
+- `application/single_app/config.py`
+- `ui_tests/test_chat_search_panel_document_row_layout.py`
+
+Code changes summary:
+- Added a filter-applied callback to the reusable searchable dropdown helper.
+- Updated the Document picker action label while users type in the document search box.
+- Changed the top Document action to show `Select All Searched`, `Clear Searched`, or `No Matching Documents` when document search is active.
+- Scoped bulk selection to visible searched document rows for Search, Analyze, and Compare.
+- Disabled the bulk action when a document search has no matching documents.
+- Updated `config.py` to version `0.241.032`.
+
+## Validation
+
+Testing approach:
+- Extended the Playwright UI regression with a real `chat-documents.js` module fixture.
+- Verified `Select All Searched` selects only matching searched document IDs for Search, Analyze, and Compare.
+- Verified no-match searches disable the bulk action and do not select hidden documents.
+
+Expected behavior after the fix:
+- Searching documents and clicking the top action selects only the currently searched documents.
+- Analyze and Compare bulk selection respects the same searched subset.
+- No-match searches cannot accidentally select all available documents.

+# PowerPoint Structured Markdown Rendering Fix
+
+## Header Information
+
+Fixed in version: **0.241.032**
+
+Issue description:
+
+Structured markdown PowerPoint exports preserved the deck shape, but still rendered too literally. A markdown title slide became a normal content slide, authored slide numbers were not visible in the generated slide footer, markdown tables were dropped from slide bodies, and trailing non-slide sections such as optional speaker notes or follow-up offers could leak into the final slide.
+
+Root cause analysis:
+
+The structured markdown export path only extracted slide titles and bullets. It did not promote a `Slide 1 - Title` section into the presentation title slide, did not parse markdown tables for inline rendering, and did not trim post-deck prose from the final slide section.

+- Promoted authored `Slide 1 - Title` sections into the real PowerPoint title slide.
+- Preserved authored slide numbers in structured slide footers.
+- Parsed markdown tables inside structured slides and rendered the first table as a native PowerPoint table on that slide.
+- Trimmed post-deck speaker notes, coverage caveats, and follow-up offer text from structured slide bodies.
+- Kept structured decks out of AI replanning so title/table improvements do not reintroduce summarization.
+
+Testing approach:
+
+- Expanded the focused PowerPoint export functional test with a representative 32-slide structured markdown deck.
+- Verified the generated deck keeps exactly 32 slides, uses a true title slide, renders the Slide 3 budget table natively, includes authored slide footer text, and excludes trailing speaker-note/follow-up text.

+## Validation
+
+Before:

+# Inline Export Action Streaming Placeholder Fix
+
+## Header Information
+
+Fixed in version: **0.241.033**
+
+Issue description:
+
+Assistant responses that matched a create/export request showed inline actions such as `Create PowerPoint Presentation` on the temporary streaming placeholder. The button appeared before the final assistant message and generated artifacts existed, which made the action confusing and unusable during response generation.
+
+Root cause analysis:
+
+The inline export action renderer looked only at the latest user prompt intent. It did not distinguish temporary `temp_ai_...` streaming placeholders from completed assistant messages, so the placeholder inherited the same create/export buttons as the final response.
+
+Related config update: `application/single_app/config.py` now sets `VERSION = "0.241.033"`.

+# PowerPoint Artifact Export Source Fix
+
+## Header Information
+
+Fixed in version: **0.241.033**
+
+Issue description:
+
+Generated Markdown artifact cards contained the full slide material for a presentation, but the nearby `Create PowerPoint Presentation` action exported the short assistant summary message instead. Users saw the correct MD artifact attached to the chat, but the PowerPoint output did not reflect that artifact content.
+
+Root cause analysis:
+
+The frontend PowerPoint export request only sent the visible assistant `message_id` and `conversation_id`. The backend export route only loaded message `content`, while generated chat artifacts are stored as separate `role: file` message records with blob-backed Markdown content.
+
+Related config update: `application/single_app/config.py` now sets `VERSION = "0.241.033"`.

+- Validated generated artifact ownership through the existing conversation/message authorization path.
+- Restricted artifact-backed PowerPoint export to generated Markdown artifacts with blob-backed content.

+- Added a direct `Create PowerPoint` button to generated Markdown artifact cards.
+- Updated the existing inline `Create PowerPoint Presentation` action to prefer an attached generated Markdown artifact when one is present.
+
+Testing approach:
+
+- Expanded the focused PowerPoint export functional test to verify artifact blob content becomes the export source.
+- Added static regression checks for the `artifact_message_id` payload and generated artifact PowerPoint button.
+- Updated UI regression coverage so inline PowerPoint actions prefer attached Markdown artifacts and generated Markdown artifact cards expose direct PowerPoint export.
+
+## Validation

+# Chat Follow-Up Prompt Actions Fix (v0.241.047)
+
+Fixed/Implemented in version: **0.241.047**
+
+## Header Information
+
+### Issue Description
+
+Assistant replies could ask useful closing questions such as "Do you want me to..." or "Would you like...", but the chat UI did not consistently turn those questions into follow-up prompt buttons.
+
+### Root Cause Analysis
+
+The follow-up action extractor only looked for a narrow set of trigger phrases and then only accepted bullet or numbered list lines. Direct question-style choices, including the pattern shown in recent Citi partnership responses, were left as plain text even when they were good next prompts.
+
+### Version Implemented
+
+`0.241.047`
+
+Related config update: `application/single_app/config.py` now sets `VERSION = "0.241.047"`.
+
+## Technical Details
+
+### Files Modified
+
+- `application/single_app/static/js/chat/chat-messages.js`
+- `application/single_app/config.py`
+- `functional_tests/test_chat_follow_up_prompt_actions.py`
+- `ui_tests/test_chat_follow_up_prompt_actions.py`
+
+### Code Changes Summary
+
+- Expanded follow-up detection to recognize direct closing questions such as "Do you want me to...", "Would you like...", "Would you prefer...", and "Should I...".
+- Added support for a standard "Suggested follow-ups" section so system prompts or agent instructions can produce a predictable button-friendly format.
+- Converted assistant-perspective wording like "give you" into user-ready prompt text like "give me" before staging the next prompt.
+- Exposed the extractor through the chat module so browser tests can validate the real parser instead of manually creating mock buttons.
+
+### Testing Approach
+
+- Updated the functional test to verify the new question-style parser helpers are present.
+- Updated the Playwright UI test to render an assistant message with direct closing questions, assert that two buttons appear, and verify clicking a button stages the user-ready prompt text.
+
+### Impact Analysis
+
+- Users can click direct follow-up choices instead of copying or retyping them.
+- Existing bullet and numbered-list suggestions continue to render as before.
+- No backend prompt or storage contract changes are required for the UI fix, though agents can now use a "Suggested follow-ups" section for more consistent results.
+
+## Validation
+
+### Before
+
+- Button rendering depended on a narrow bullet-list pattern after phrases like "If you want".
+- Direct questions such as "Do you want me to make this stricter...?" stayed as plain text.
+
+### After
+
+- Direct follow-up questions and explicit "Suggested follow-ups" sections are parsed into safe DOM-created buttons.
+- Clicking a generated button stages the prompt with the existing cancelable send countdown behavior.

+# Chat Follow-Up and CSV Action Fix (v0.241.050)
+
+Fixed/Implemented in version: **0.241.050**
+
+## Header Information
+
+### Issue Description
+
+Assistant follow-up suggestions could render twice: once as visible assistant text and again as prompt buttons. Some natural export phrases, such as requesting a shorter slide deck or asking to turn a table into CSV, also did not consistently trigger the expected quick actions or generated CSV artifact.
+
+### Root Cause Analysis
+
+The chat renderer appended follow-up prompt buttons after the assistant message body but left the original trailing suggestion section in the sanitized Markdown output. Inline export actions also required a narrower set of creation verbs, and CSV/table artifact detection used duplicated marker lists that missed common phrasing such as "turn that into a csv" and "create a table".
+
+### Version Implemented
+
+`0.241.050`
+
+Related config update: `application/single_app/config.py` now sets `VERSION = "0.241.050"`.
+
+## Technical Details
+
+### Files Modified

+- `ui_tests/test_chat_follow_up_prompt_actions.py`
+- `ui_tests/test_chat_inline_export_action_buttons.py`
+
+### Code Changes Summary
+
+- Capped assistant follow-up prompt buttons at three suggestions with a shared constant.
+- Stripped the trailing recognized follow-up suggestion section from rendered assistant Markdown when follow-up buttons are created.
+- Broadened inline export intent detection to handle natural deck and presentation wording such as "provide a 5-slide executive deck" and "turn this into a presentation".
+- Expanded CSV/table request markers to include common conversion language such as "turn that into a csv", "convert this to csv", and "create a table".
+- Reused the assistant table CSV marker list in the tabular generated output detector so CSV/table request handling stays consistent.
+
+### Testing Approach
+
+- Updated source-level functional coverage for follow-up rendering hooks, the three-button cap, duplicate source stripping, and deck export wording.
+- Updated assistant table CSV artifact coverage for natural CSV/table request phrases.
+- Updated Playwright UI tests for capped follow-up buttons without duplicate visible source text and deck wording export actions.
+
+### Impact Analysis
+
+- Users see up to three concise follow-up buttons without the same suggestion text repeated in the assistant response.
+- Follow-up prompts that mention a slide deck are more likely to produce the existing PowerPoint quick action on the next assistant response.
+- Natural CSV/table conversion requests create downloadable CSV artifacts whenever the assistant response or tabular workflow can supply parseable table data.
+
+## Validation
+
+### Before
+
+- Assistant suggestions could appear as both list text and buttons.
+- "Please provide a shorter 5-slide executive deck" did not satisfy the inline export verb gate.
+- "turn that into a csv" and "create a table" were not recognized by all CSV/table artifact paths.
+
+### After
+
+- Recognized trailing follow-up sections render as buttons only, capped at three.
+- Natural presentation/deck wording is included in inline export intent detection.
+- CSV/table request markers are shared and include the common conversion phrases.

+# Standard Chat Document Action Payload Fix
+
+Version: 0.241.075
+
+Fixed/Implemented in version: **0.241.075**
+
+## Issue Description
+
+After the chat action selector was added, the default `Search Documents` option still serialized disabled `document_action` and `analyze` payload blocks. The underlying standard chat route is supposed to keep the legacy prompt flow, but this changed the request shape for normal chat turns and made tabular questions more likely to fall back to schema-only behavior.
+
+## Root Cause Analysis
+
+The chat client always built the shared document-action payload, even when the selected action type was `none`. That meant the default document-search path no longer matched the legacy request contract that tabular analysis had already been tuned around.
+
+## Technical Details
+
+### Files Modified
+
+- `application/single_app/static/js/chat/chat-messages.js`
+- `application/single_app/config.py`
+- `functional_tests/test_standard_chat_document_action_payload_fix.py`
+- `functional_tests/test_document_analysis_feature.py`
+
+### Code Changes Summary
+
+- Changed chat payload assembly so `document_action` is only sent when the user explicitly selects an opt-in action.
+- Limited the legacy `analyze` compatibility payload to analysis runs only.
+- Added a focused regression test that verifies `Search Documents` keeps the normal payload shape while opt-in actions still serialize their action-specific fields.
+
+## Testing And Validation
+
+- Functional regression: `functional_tests/test_standard_chat_document_action_payload_fix.py`
+- Updated wiring check: `functional_tests/test_document_analysis_feature.py`
+
+## Impact Analysis
+
+- `Search Documents` now preserves the legacy request contract again.
+- Document analysis and comparison continue to use the shared document-action routes.
+- Tabular questions in the default document-search path are less likely to degrade into schema-only fallbacks caused by the changed request shape.

+# SQL Container ODBC Driver Registry Path Fix
+
+Version: 0.241.080
+
+Fixed/Implemented in version: **0.241.080**
+
+## Issue Description
+
+`azd deploy` container builds started failing in Azure Container Registry during the ODBC runtime packaging step with `cp: cannot stat '/etc/odbcinst.ini': No such file or directory`.
+
+## Root Cause Analysis
+
+The SQL container runtime packaging logic assumed that `msodbcsql18` would always register the unixODBC driver in `/etc/odbcinst.ini`.
+
+On Azure Linux 3, the package install reports its driver target directory through `odbcinst -j`, and the build log showed that the active location was `/etc/unixODBC`. The Dockerfile hard-coded the older root-level path, so the build failed before the distroless runtime image could be assembled.
+
+## Technical Details
+
+### Files Modified
+
+- `application/single_app/Dockerfile`
+- `application/single_app/config.py`
+- `functional_tests/test_sql_container_odbc_runtime.py`
+
+### Code Changes Summary
+
+- Updated the Dockerfile to detect the unixODBC driver registry directory with `odbcinst -j` instead of assuming `/etc/odbcinst.ini`.
+- Copied the detected `odbcinst.ini` path into the `/odbc-runtime` payload so the final distroless image preserves the package-selected layout.
+- Kept a compatibility copy under `/etc/odbcinst.ini` when the package uses a subdirectory path.
+- Extended the existing SQL container regression test to verify the dynamic path handling and to fail if the Dockerfile regresses to the old hard-coded copy path.
+
+## Testing And Validation
+
+- Focused Dockerfile diagnostics in the editor after the packaging-step update.
+- Functional regression: `functional_tests/test_sql_container_odbc_runtime.py`
+
+## Impact Analysis
+
+- ACR builds no longer fail when Azure Linux 3 registers the SQL Server ODBC driver under `/etc/unixODBC` instead of `/etc`.
+- The distroless runtime keeps the unixODBC driver registry in the same location reported by the installed package.
+- This change is a follow-up to the earlier SQL runtime packaging work documented in `docs/explanation/fixes/SQL_CONTAINER_ODBC_RUNTIME_FIX.md`.

+# Generated Markdown Artifact Extension Fix
+
+Version: 0.241.081
+
+Fixed/Implemented in version: **0.241.081**
+
+## Issue Description
+
+Generated Markdown artifacts, including Deep Research ledger files, could be saved as chat artifacts with Markdown content but a `.json` filename. When a user selected **Add to Workspace**, the workspace processor treated the artifact as JSON and failed with an invalid JSON structure error.
+
+## Root Cause Analysis
+
+Generated artifact filename normalization only preserved `.json` and `.csv` extensions. Markdown artifact uploads passed filenames such as `deep_research_ledger_20260521_194546.md`, but the helper renamed them to `.json` before storing the chat artifact. The promotion route then reused that stored filename, so Markdown bytes entered the workspace ingestion pipeline as a JSON document.
+
+## Technical Details
+
+### Files Modified
+
+- `application/single_app/functions_simplechat_operations.py`
+- `application/single_app/route_enhanced_citations.py`
+- `application/single_app/config.py`
+- `functional_tests/test_generated_markdown_artifact_extension.py`
+
+### Code Changes Summary
+
+- Updated generated artifact filename normalization to preserve real extensions instead of forcing non-CSV artifacts to `.json`.
+- Added promotion/download filename resolution that uses generated artifact output-format metadata to repair legacy Markdown artifacts already stored with `.json` names.
+- Added regression coverage for Deep Research-style Markdown artifact filenames and legacy `.json` artifact promotion.
+
+## Testing And Validation
+
+- Functional regression: `functional_tests/test_generated_markdown_artifact_extension.py`
+- Python compile validation for the touched backend modules and regression test.
+
+## Impact Analysis
+
+- New Deep Research ledger artifacts are stored and promoted with `.md` filenames.
+- Existing Markdown artifacts that were saved as `.json` can be added to a workspace using the metadata-corrected `.md` filename.
+- JSON and CSV generated artifacts continue to keep their expected extensions.

+# SQL Container ODBCINST Path Normalization Fix
+
+Version: 0.241.081
+
+Fixed/Implemented in version: **0.241.081**
+
+## Issue Description
+
+After updating the SQL container runtime packaging to use `odbcinst -j`, Azure Container Registry builds still failed while assembling the distroless ODBC payload.
+
+## Root Cause Analysis
+
+On Azure Linux 3, the `DRIVERS` entry returned by `odbcinst -j` resolves to the full file path `/etc/unixODBC/odbcinst.ini`, not just the containing directory.
+
+The previous Dockerfile revision treated that value as a directory and appended another `/odbcinst.ini`, producing an invalid path like `/etc/unixODBC/odbcinst.ini/odbcinst.ini`.
+
+## Technical Details
+
+### Files Modified
+
+- `application/single_app/Dockerfile`
+- `application/single_app/config.py`
+- `functional_tests/test_sql_container_odbc_runtime.py`
+
+### Code Changes Summary
+
+- Normalized the `odbcinst -j` result into a concrete `driver_config_file` first.
+- Added shell-only handling for both supported output shapes: a direct `odbcinst.ini` file path or a directory path.
+- Derived the runtime copy target directory from the normalized file path before copying the ODBC registry into `/odbc-runtime`.
+- Extended the SQL container regression test to assert the file-or-directory normalization logic.
+
+## Testing And Validation
+
+- Local functional regression: `functional_tests/test_sql_container_odbc_runtime.py`
+- Local container reproduction against `mcr.microsoft.com/azurelinux/base/python:3.12` confirmed that `odbcinst -j` reports `/etc/unixODBC/odbcinst.ini` on Azure Linux 3.
+
+## Impact Analysis
+
+- Local Docker builds and ACR task builds no longer depend on guessing whether `odbcinst -j` returns a directory or the full file path.
+- The SQL Server ODBC runtime packaging step now works with the actual Azure Linux 3 unixODBC layout used by `msodbcsql18`.

+# Chat Stream Lifecycle Observability Fix
+
+## Overview
+
+Fixed/Implemented in version: **0.241.109**
+Related config update: `application/single_app/config.py` now reports `VERSION = "0.241.109"`.
+Related functional test: `functional_tests/test_chat_stream_lifecycle_observability.py`
+
+This change improves diagnostics for long-running chat streams, including document analysis runs that can stay active for 30 to 40 minutes.
+
+## Issue Description
+
+The streaming chat path already continued running on the backend after a browser-side disconnect, but the logging and status surfaces were too thin to prove what happened after a frontend failure.
+
+Before this fix:
+- Backend logs showed request start and some terminal conditions, but not a clear lifecycle for detach, reattach, keepalive, queue pressure, and terminal state.
+- `/api/chat/stream/status/<conversation_id>` only reported whether a stream was currently pending.
+- Frontend stream failures lived mostly in browser console output and were not reported back to the backend.
+- Operators could not reliably answer whether a detached stream was still running, had completed, or had failed later.
+
+## Root Cause Analysis
+
+The stream session metadata only tracked a narrow `active` state and replay cache information. The stream bridge and reattach route handled disconnects and recovery, but they did not persist a richer lifecycle model or emit correlated structured logs for those transitions.
+
+## Technical Details
+
+### Files Modified
+- `application/single_app/route_backend_chats.py`
+- `application/single_app/static/js/chat/chat-streaming.js`
+- `application/single_app/config.py`
+- `functional_tests/test_chat_stream_lifecycle_observability.py`
+
+### Code Changes Summary
+- Added backend stream lifecycle status helpers and persisted status snapshots for:
+  - start
+  - first content emitted
+  - keepalive
+  - detach
+  - reattach
+  - queue backpressure
+  - completion
+  - error
+- Extended stream status responses to include lifecycle metadata instead of only a pending flag.
+- Added a client-event endpoint so the frontend can report stream request errors, read errors, premature endings, aborts, and recovery attempts back to backend logs.
+- Added frontend best-effort telemetry calls around the stream failure and recovery path.
+- Bumped the app version to `0.241.109`.
+
+### Operational Impact
+- Backend logs can now show whether a long-running stream detached from the browser and continued to run.
+- Reattach attempts are logged explicitly.
+- Status queries can show detach, reattach, keepalive, queue backpressure, and terminal status details during the replay TTL window.
+- Frontend stream failures are no longer limited to console-only diagnostics when the reporting path is available.
+
+## Validation
+
+### Test Coverage
+- `functional_tests/test_chat_stream_lifecycle_observability.py`
+
+### Verification Performed
+- Python diagnostics on `route_backend_chats.py`
+- `python -m py_compile application/single_app/route_backend_chats.py`
+- JavaScript diagnostics on `application/single_app/static/js/chat/chat-streaming.js`
+- `node --check application/single_app/static/js/chat/chat-streaming.js`
+
+### Before and After
+Before:
+- Stream status exposed only pending/reattachable.
+- Frontend failures were mostly visible only in browser console logs.
+- No explicit lifecycle metadata for detach, reattach, keepalive, queue backpressure, and terminal status.
+
+After:
+- Stream status exposes lifecycle metadata and richer status fields.
+- Backend logs capture detach, reattach, keepalive, queue backpressure, and terminal status transitions.
+- The frontend reports failure and recovery events to the backend through the client-event endpoint.
+
+## Limitations
+
+This is best-effort observability, not a hard guarantee for every network partition. If the browser loses all connectivity, the frontend may be unable to send the client-event report. In that case, the backend lifecycle state and terminal logging still provide the primary source of truth.

+# Fact Memory History Context Leak Fix (v0.241.128)
+
+Fixed/Implemented in version: **0.241.128**
+
+## Header Information
+
+### Issue Description
+
+Assistant replies could expose internal prior citation/tool scaffolding in the visible chat bubble, including `Prior tool results` content from saved instruction memory or fact memory citations.
+
+### Root Cause Analysis
+
+`application/single_app/route_backend_chats.py` intentionally appends compact prior citation context to assistant turns before sending conversation history to the model. This helps follow-up questions reuse tabular and source evidence, but fact-memory citations are already injected as fresh current-turn system context and are also available through the citation UI. Replaying those citations inside prior assistant history gave the model answer-shaped text that could be quoted back to the user.
+
+### Version Implemented
+
+`0.241.128`
+
+## Technical Details
+
+### Files Modified
+
+- `application/single_app/route_backend_chats.py`

+- `functional_tests/test_fact_memory_history_context_leak_fix.py`
+- `docs/explanation/fixes/v0.241.128/FACT_MEMORY_HISTORY_CONTEXT_LEAK_FIX.md`
+
+### Code Changes Summary
+
+- Added a history-replay exclusion for fact-memory citation records, including `Instruction Memory`, `Fact Memory Recall`, and citations with the `fact_memory` plugin name.
+- Kept tabular citation summaries eligible for follow-up grounding so users can still ask short follow-up questions about prior workbook/tool results.
+- Added an explicit internal-grounding instruction to the remaining supporting citation context block so the model is told not to quote, summarize, reveal, or mention the hidden context labels or raw tool payloads.
+- Bumped the application version to `0.241.128`.
+
+### Testing Approach
+
+- Added `functional_tests/test_fact_memory_history_context_leak_fix.py`.
+- Verified fact-memory-only citations do not produce a `Prior tool results` block in assistant history text.
+- Verified mixed fact-memory and tabular citations still preserve tabular evidence for follow-up grounding while excluding the saved memory payloads.
+- Verified documentation and `config.py` version alignment for the fix.
+
+## Validation
+
+### Before
+
+- Prior assistant turns with instruction/fact memory citations could be serialized back into model history under `Prior tool results`.
+- The model could echo saved memory citation JSON in the visible response even though those details belonged in citations/thoughts, not the assistant answer.
+
+### After
+
+- Saved instruction/fact memory citation payloads remain available through citation metadata but are not replayed as prior assistant-history text.
+- Tabular citation evidence remains available for follow-up grounding.
+- The remaining hidden citation context includes a stronger instruction to avoid revealing internal context labels or tool payloads.

+# Foundry Metadata Scope List Fix
+
+Fixed in version: **0.241.129**
+
+## Issue Description
+
+Foundry workflow and new-Foundry Responses calls could fail with HTTP 400 when SimpleChat passed internal scope arrays such as `active_group_ids` into the outbound Foundry `metadata` object. Foundry metadata values must stay under 512 characters, while a user with many active groups can exceed that limit when the list is stringified.
+
+## Root Cause Analysis
+
+SimpleChat needs `active_group_ids`, `active_public_workspace_ids`, and `selected_document_ids` internally to resolve authorized selected files and workspace context. The payload builders were also stringifying those internal lists into the Foundry request metadata, where they were not required and could exceed Foundry's metadata limits.
+
+## Technical Details
+
+- Files modified: `application/single_app/foundry_agent_runtime.py`, `functional_tests/test_foundry_workflow_agent_payload.py`, `application/single_app/config.py`
+- Added Foundry response metadata sanitization that omits internal scope lists before sending requests to Foundry.
+- Preserved internal metadata for SimpleChat file resolution before outbound payload construction.
+- Added scalar metadata truncation to 512 characters to stay within Foundry request constraints.
+
+## Validation
+
+- Added a regression test that builds workflow and new-Foundry payloads with large `active_group_ids`, `active_public_workspace_ids`, and `selected_document_ids` lists.
+- Confirmed the internal lists are not present in outbound Foundry metadata and long scalar metadata is capped at 512 characters.
+- Related config.py version update: `VERSION = "0.241.129"`.

+# Foundry Upload Context User Scope Fix
+
+Fixed in version: **0.241.130**
+
+## Issue Description
+
+Foundry workflow requests received attached image/file bytes and SimpleChat OCR/vision context, but the USPTO prior art workflow still routed to its unusable-upload branch. Azure CLI inspection of `wfresp_7ee365ebb342287100BhgOThogMbUJTVGCOV68PwP6xml1bBlr` confirmed the request contained both `input_text` and `input_file` content, while the workflow output executed `send_unusable_intake_output`.
+
+## Root Cause Analysis
+
+The uploaded-file OCR and vision context was present in SimpleChat's system-context portion of the prompt. Controlled Foundry probes showed that putting the same compact file description directly in user-scoped text caused the workflow to proceed past the unusable-upload branch, indicating the workflow or invoked Foundry agents were using only the user request text for intake.
+
+## Technical Details

+- Files modified: `application/single_app/foundry_agent_runtime.py`, `functional_tests/test_foundry_workflow_agent_payload.py`, `application/single_app/config.py`
+- When Foundry REST file parts are attached, SimpleChat now extracts existing upload context blocks from chat history and creates a compact `Attached file searchable summary`.
+- Foundry workflow payloads use a clean one-shot user message containing the compact summary and the latest user request, instead of sending the full SimpleChat role-packed `SYSTEM:`/`USER:` history text.
+- Common phrases such as `file ive uploaded` are rewritten to reference the attached file summary so workflow intake agents do not branch into upload-placeholder handling.
+- Normal new-Foundry Responses agents keep their multi-message payload shape, with the compact summary prepended to the latest user message when file parts are attached.
+
+## Validation
+
+- Azure CLI inspection confirmed the original workflow response received `input_file` with `data:image/png;base64,...` and routed to `send_unusable_intake_output`.
+- Controlled Azure CLI-token REST probes showed exact SimpleChat text plus file repeated the unusable branch. A direct compact summary plus cleaned request completed the prior-art workflow and reached `send_prior_art_report`.
+- A post-fix builder smoke probe confirmed the workflow payload no longer includes `SYSTEM:` role-packed text or literal `file ive uploaded` wording; the non-streaming Foundry request advanced into the longer prior-art path and returned service timeout instead of the unusable-upload branch.
+- Added regression tests that verify uploaded image/file context is compacted into user-scoped Foundry workflow and new-Foundry payload text when file inputs are attached.
+- Related config.py version update: `VERSION = "0.241.130"`.

+# File Sync Tag Definition Application Fix - Version 0.241.131
+
+Fixed/Implemented in version: **0.241.131**
+
+Related version update: `application/single_app/config.py` was incremented to `0.241.131` for this fix.
+
+## Issue Description
+
+File Sync source definitions could include fixed tags and folder-derived tag rules, but documents that were already synced and later detected as unchanged did not have those current definitions applied. A source could keep syncing successfully while existing documents stayed untagged or retained tags from an older source definition.
+
+## Root Cause Analysis
+
+The File Sync run loop skipped document metadata updates whenever a remote file was considered unchanged by modification token, timestamp, size, or matching content hash. That shortcut touched the sync item record but did not reconcile the associated document metadata against the source's current `fixed_tags` and `folder_tag_mode` settings.
+
+## Technical Details
+
+### Files Modified
+
+- `application/single_app/functions_file_sync.py`
+- `application/single_app/config.py`
+- `functional_tests/test_file_sync_tag_definition_application.py`
+
+### Code Changes Summary
+
+- Added a shared helper to resolve the document context for File Sync sources.
+- Added tag-definition creation through a shared helper used by both new synced documents and existing synced documents.
+- Added reconciliation for unchanged remote files so current source-defined tags are applied to the existing document metadata when the derived tags differ.
+- Preserved the existing unchanged-file shortcut for content processing; only document tags are updated when required.
+
+### Testing Approach
+
+- Added `functional_tests/test_file_sync_tag_definition_application.py` to validate that both unchanged-file paths call tag reconciliation.
+- Validated that reconciliation derives tags from source definitions, ensures tag definitions exist, reads current document metadata, and calls `update_document(tags=tags)` only when needed.
+
+## Validation
+
+### Test Results
+
+- `functional_tests/test_file_sync_tag_definition_application.py` covers the regression path without requiring live Cosmos DB or a remote file share.
+
+### Before/After Comparison
+
+- Before: unchanged synced files bypassed tag updates, so changing sync definitions did not update existing documents.
+- After: unchanged synced files reconcile their document tags against the current sync definition during a sync run.
+
+### User Experience Improvements
+
+- File Sync tags now stay aligned with the configured source definitions after fixed tags or folder tag behavior changes.
+- Users can update sync definitions and run sync again without needing to force remote file content changes just to apply tags.

+# Assigned Knowledge Personal Scope Lock Fix v0.241.133
+
+Fixed in version: **0.241.133**
+
+## Issue Description
+
+Personal agents with Assigned Knowledge from a public workspace could be treated as public-workspace conversations after the first grounded response. When workspace scope lock was enabled, the conversation then locked to the public workspace and the personal agent could become unavailable for follow-up use.
+
+## Root Cause Analysis
+
+The streaming chat path rebuilt selected-agent metadata after the initial request metadata was created. That later metadata did not preserve the `assigned_knowledge_enabled` flag used by conversation metadata collection to keep personal assigned-knowledge agents anchored to the personal workspace.
+
+The frontend also did not reflect the personal agent owner scope when applying Assigned Knowledge, so the scope selector could show only assigned source workspaces before the first response.
+
+## Technical Details
+
+### Files Modified
+
+- `application/single_app/route_backend_chats.py`
+- `application/single_app/static/js/chat/chat-documents.js`
+- `functional_tests/test_chat_scope_selector_sync.py`
+- `application/single_app/config.py`
+
+### Code Changes Summary
+
+- Added a shared route helper for selected-agent metadata so streaming, non-streaming, and document-action chat paths preserve `assigned_knowledge_enabled` consistently.
+- Updated Assigned Knowledge frontend scope application to select the agent owner scope along with assigned source scopes.
+- Kept Assigned Knowledge retrieval behavior unchanged: assigned sources still control what the agent searches, and user document selection remains disabled unless user workspace context is enabled for the agent.
+- Updated `config.py` from version `0.241.132` to `0.241.133` for fix tracking.
+
+### Testing Approach
+
+- Added functional coverage in `functional_tests/test_chat_scope_selector_sync.py` to verify route metadata preservation and frontend assigned-knowledge scope selection wiring.
+- Existing Assigned Knowledge policy coverage continues to validate that personal agents with public Assigned Knowledge keep personal as primary context and include the assigned public workspace as a locked context.
+
+## Impact Analysis
+
+- Personal agents remain usable after a public Assigned Knowledge response.
+- Scope lock can include both the personal owner scope and assigned public workspace without allowing users to add personal documents when the agent's user workspace context option is disabled.
+- Public Assigned Knowledge source visibility and retrieval restrictions are preserved.
+
+## Validation
+
+### Expected Before/After Behavior
+
+Before the fix, a personal agent using assigned public knowledge could lock the conversation as public after the first response.
+
+After the fix, the conversation remains personal-owned, with the assigned public workspace represented as locked secondary context.
+
+### Test Results
+
+Validation is performed by the focused functional test and syntax checks for the changed Python and JavaScript files.

+# Authenticated Request Login Activity Fix
+
+Fixed/Implemented in version: **0.241.142**
+
+## Overview
+
+This fix closes the gap between explicit OAuth callback logins and real authenticated usage. Previously, activity tracking only recorded `user_login` when the `/getAToken` callback completed. Users who arrived with an already-authenticated session or seamless SSO reuse could browse the app without creating the login-style activity that the Control Center and profile dashboards rely on.
+
+Version implemented:
+`config.py` now reports `VERSION = "0.241.142"` for this fix.
+
+## Issue Description
+
+- Login analytics depended on an explicit callback event rather than the broader fact that the user had an authenticated browser session.
+- Passive SSO or session reuse could authenticate the user successfully but leave login metrics empty or understated.
+- Simply logging every authenticated request would have created noisy over-counting, especially for API-heavy pages.
+
+## Root Cause
+
+- The application treated `user_login` as a one-time OAuth callback event instead of a reusable authenticated-session signal.
+- The authenticated request pipeline had no throttled activity writer for browser page access.
+- The explicit callback flow had no session marker to prevent a duplicate login record on the immediate redirect to the landing page.
+
+## Technical Changes
+
+### Throttled Authenticated Request Tracking
+
+Changes implemented:
+
+- Added a shared authenticated-request helper in `functions_activity_logging.py` that records a `user_login` activity with `login_method = authenticated_request`.
+- Added a session-scoped throttle window so repeated authenticated page loads do not emit a record on every request.
+- Captured request metadata such as `request_path`, `request_method`, and `auth_signal` for later diagnostics.
+
+Files involved:
+
+- `application/single_app/functions_activity_logging.py`
+- `application/single_app/app.py`
+
+Behavioral outcome:
+
+Authenticated page visits now show up in the existing login analytics even when the user did not intentionally click a login button during that session.
+
+### OAuth Callback Deduplication
+
+Changes implemented:
+
+- Marked the session immediately after the explicit `/getAToken` callback logs `user_login`.
+- Reused that session marker to suppress an immediate second `user_login` on the redirect to `/`.
+
+Files involved:
+
+- `application/single_app/route_frontend_authentication.py`
+
+Behavioral outcome:
+
+Explicit callback logins remain single-counted while passive authenticated navigation still becomes visible later in the session.
+
+## Files Modified
+
+- `application/single_app/functions_activity_logging.py`
+- `application/single_app/app.py`
+- `application/single_app/route_frontend_authentication.py`
+- `application/single_app/config.py`
+- `functional_tests/test_authenticated_request_login_activity.py`
+
+## Validation
+
+Testing approach:
+
+- Added a focused functional regression test that loads `functions_activity_logging.py` with stubbed dependencies so the new throttle and dedup behavior can be exercised without a live Cosmos dependency.
+- Ran targeted compile checks on the edited Python files.
+
+Validation performed for this implementation:
+
+- `python -m py_compile application/single_app/functions_activity_logging.py`
+- `python -m py_compile application/single_app/app.py`
+- `python -m py_compile application/single_app/route_frontend_authentication.py`
+- `python -m py_compile application/single_app/config.py`
+- `python -m py_compile functional_tests/test_authenticated_request_login_activity.py`
+- `python functional_tests/test_authenticated_request_login_activity.py`
+
+## Before And After
+
+Before:
+
+- Login metrics depended almost entirely on explicit OAuth callback completions.
+- Passive SSO/session-reuse visits could authenticate successfully without contributing to login analytics.
+- A naive request-level fix risked over-counting every authenticated browser/API request.
+
+After:
+
+- Authenticated browser page requests can emit a throttled `user_login` record when no recent login activity has been recorded in the current session.
+- Explicit OAuth callback logins still record normally and are not immediately double-counted on redirect.
+- Existing dashboards that already query `activity_type = 'user_login'` now see a more representative picture of real authenticated use.
+
+## User Experience Impact
+
+- Admins get more representative login activity in the Control Center and profile trends for users who rely on seamless SSO.
+- Users do not see any UI change.
+- Login metrics should remain substantially less noisy than per-request tracking because the authenticated-request signal is throttled and limited to browser GET requests.

+# Assistant Table CSV Artifact Fix
+
+Fixed/Implemented in version: **0.241.143**
+
+## Overview
+
+This fix creates a downloadable CSV artifact when a user explicitly asks the assistant to turn content into a table and the assistant response contains a parseable table. The generated CSV is saved to the current chat so the existing generated-export UI can show a `Download CSV` button immediately on the assistant message.
+
+Version implemented:
+`config.py` now reports `VERSION = "0.241.143"` for this fix.
+
+## Issue Description
+
+- Users could ask for pasted content to be converted into a table and receive a rendered table in the assistant reply.
+- The model sometimes added follow-up text such as offering to create a CSV, but the application did not attach the CSV proactively.
+- Existing generated JSON/CSV workflows only handled tabular-processing tool results, so model-rendered tables from plain chat responses had no saved export artifact.
+
+## Root Cause
+
+- Generated tabular artifacts were tied to tabular plugin invocation payloads with source rows.
+- Plain user-pasted content converted into a table by the model did not create a tabular plugin invocation, leaving no source candidate for `maybe_create_tabular_generated_output(...)`.
+- The chat UI already knew how to render generated artifact cards, but the assistant message metadata never received artifact details for response-only tables.
+
+## Technical Changes
+
+### Assistant Response Table Extraction
+
+Changes implemented:
+
+- Added `functions_assistant_table_exports.py` to detect explicit table/CSV-style user requests.
+- Extracted rows from Markdown pipe tables and tab-separated assistant table output.
+- Serialized extracted rows to CSV while preserving column order and a three-row preview for the generated artifact card.
+
+Files involved:
+
+- `application/single_app/functions_assistant_table_exports.py`
+
+### Chat Artifact Attachment
+
+Changes implemented:
+
+- Added `maybe_create_assistant_table_generated_output(...)` in `route_backend_chats.py`.
+- Saved generated CSV files through `upload_generated_analysis_artifact_for_current_user(...)`, keeping authorization and chat artifact storage on the existing path.
+- Attached artifact metadata to normal chat, streaming chat, and document-action assistant messages before metadata is persisted and returned to the browser.
+- Avoided duplicate CSV attachments when a tabular workflow already produced a CSV artifact.
+
+Files involved:
+
+- `application/single_app/route_backend_chats.py`
+- `application/single_app/functions_simplechat_operations.py` (existing upload path reused)
+
+### Table Request Intent Coverage
+
+Changes implemented:
+
+- Broadened table-output intent markers to include phrasing such as `turn this into a table`, `format this as a table`, and `table for me`.
+- This allows both existing tabular workflows and the new assistant-response table fallback to recognize common user wording.
+
+## Files Modified
+
+- `application/single_app/functions_assistant_table_exports.py`
+- `application/single_app/route_backend_chats.py`
+- `application/single_app/config.py`
+- `functional_tests/test_assistant_table_csv_artifact.py`
+
+## Validation
+
+Testing approach:
+
+- Added a focused functional test for Markdown table parsing, tab-separated table parsing, non-table request exclusion, and route wiring.
+- Ran compile checks on the edited Python files.
+
+Validation performed for this implementation:
+
+- `python -m py_compile application/single_app/functions_assistant_table_exports.py`
+- `python -m py_compile application/single_app/route_backend_chats.py`
+- `python -m py_compile application/single_app/config.py`
+- `python -m py_compile functional_tests/test_assistant_table_csv_artifact.py`
+- `python functional_tests/test_assistant_table_csv_artifact.py`
+
+## Before And After
+
+Before:
+
+- A table-formatted assistant reply could render correctly but had no attached CSV.
+- Users had to ask a second time for a CSV even when the answer already contained enough table data to export.
+
+After:
+
+- Explicit table-format requests that produce parseable assistant tables now attach a chat-scoped CSV artifact.
+- The assistant message metadata feeds the existing generated-export UI, so users see the same `Download CSV` control used by other generated tabular workflows.
+- Existing tabular workflow CSV exports are not duplicated.
+
+## User Experience Impact
+
+- Users get a ready-to-download CSV when they ask the assistant to make a table from pasted content.
+- The generated file stays with the conversation and can be downloaded from the assistant response card.
+- Existing JSON/CSV tabular workflows continue to work unchanged.

+# Chat Optional Feature Initialization Fix
+
+Fixed in version: **0.241.145**
+
+## Issue Description
+
+Opening Chats could log noisy browser-console messages when optional chat features were disabled or unavailable in the rendered page. In particular, agent initialization emitted `Agent Init Error: enable-agents-btn not found.` when Semantic Kernel was enabled but per-user agents were not rendered.
+
+## Root Cause
+
+Chat modules are imported by other chat modules, so their initialization paths can run even when the matching optional controls are intentionally absent from `chats.html`. The agent initializer treated missing controls as an error, and the speech initializer was called by the shared chat on-load module even when speech input was disabled.
+
+## Technical Details
+
+Files modified:
+
+- `application/single_app/static/js/chat/chat-agents.js`
+- `application/single_app/static/js/chat/chat-speech-input.js`
+- `application/single_app/config.py`
+- `functional_tests/test_chat_optional_feature_initializers.py`
+- `ui_tests/test_chat_optional_feature_initializers_quiet.py`
+
+Code changes summary:
+
+- Added an agent-controls availability guard so agent initialization and dropdown population return quietly when the agent enable button or selector controls are not present.
+- Added a speech-input feature flag guard so speech initialization returns quietly when `window.appSettings.enable_speech_to_text_input` is false.
+- Removed disabled-feature console error and warning paths for optional missing controls.
+
+Config version update:
+
+- Updated `application/single_app/config.py` from `0.241.144` to `0.241.145`.
+
+Testing approach:
+
+- Added a functional regression test that validates the quiet optional-initializer guards remain in place.
+- Added a Playwright UI regression test that opens Chats and fails if the agent init error or speech missing-control warning appears in the browser console.
+
+## Validation
+
+Before:
+
+- Chats could log `Agent Init Error: enable-agents-btn not found.` when agents were not rendered for the current configuration.
+- Chats could log `Speech input button not found in DOM` when speech input was disabled but the shared chat on-load module still called the initializer.
+
+After:
+
+- Disabled or unavailable optional chat features no-op quietly.
+- Agent and speech initializers still attach normal controls when their matching DOM is present.

+# Agents Sidebar Settings Fallback Fix
+
+Fixed in version: **0.241.219**

+## Issue Description
+
+Pages that render the shared sidebar with only `app_settings` in the template context could fail with `jinja2.exceptions.UndefinedError: 'settings' is undefined` after the Agents navigation link was added under Chat.
+
+## Root Cause
+
+The new Agents sidebar link used `settings.enable_semantic_kernel` directly. Some frontend routes, including the landing page, pass sanitized settings as `app_settings` but do not pass a separate `settings` variable.
+
+## Technical Details
+
+Files modified:
+

+- Updated Agents and related sidebar feature gates to use `sidebar_settings` instead of directly requiring `settings`.
+- Added regression assertions to the Agents catalog functional test.
+
+## Validation
+
+- `functional_tests/test_agents_catalog_feature.py` validates the fallback exists and direct `settings.enable_semantic_kernel` sidebar checks are not reintroduced.

+# Tabular SK Python 3.13 Kernel Parameter Fix
+
+Fixed in version: **0.242.068**
+
+## Issue Description
+
+Semantic Kernel tool-call parsing can fail on Python 3.13 when public plugin parameters are annotated as `Annotated[Optional[str], ...]`. During argument coercion, Semantic Kernel may try to instantiate `typing.Optional[str]`, which is a `Union[str, None]` and is not callable.
+
+The failure appears as a `TypeError` similar to `Cannot instantiate typing.Union` and can prevent tabular workbook tools from running even when the same tool signatures worked under older runtime behavior.
+
+## Root Cause Analysis
+
+The affected surface is the public `@kernel_function` method signatures in `application/single_app/semantic_kernel_plugins/tabular_processing_plugin.py`. These signatures are parsed by Semantic Kernel, unlike normal internal helper annotations.
+
+Internal helpers can safely keep `Optional[str]` annotations. Public Semantic Kernel tool parameters should use concrete parseable types, while defaults such as `= None` continue to represent omitted optional arguments.
+
+## Technical Details
+
+### Files Modified
+
+- `application/single_app/semantic_kernel_plugins/tabular_processing_plugin.py`
+- `functional_tests/test_tabular_kernel_parameter_annotations.py`
+- `application/single_app/config.py`
+
+### Code Changes Summary
+
+- Replaced public `@kernel_function` parameter annotations from `Annotated[Optional[str], ...]` to `Annotated[str, ...]`.
+- Kept `None` defaults for optional tool parameters so omitted values remain supported.
+- Preserved internal helper type hints that are not parsed by Semantic Kernel.
+- Added a regression test that parses the tabular plugin AST and fails if any `@kernel_function` parameter reintroduces `Annotated[Optional[str], ...]`.
+
+## Validation
+
+Validation includes:
+
+- Python compile checks for the tabular plugin and new functional test.
+- `functional_tests/test_tabular_kernel_parameter_annotations.py`.
+- Existing tabular pagination and relational helper tests to ensure the annotation cleanup does not change runtime behavior.
+
+## Impact Analysis
+
+This change supports both Python 3.12 and Python 3.13. Tool-call behavior remains the same for callers: optional arguments can still be omitted, and plugin code still treats `None` and empty strings as not provided where appropriate.
+
+## Attribution
+
+This fix was inspired by and adapted from PR #892 by @vivche, which identified the Python 3.13 Semantic Kernel `Optional[str]` parameter parsing issue while investigating tabular SK multi-endpoint workbook analysis.
+
+The multi-endpoint route changes from PR #892 were not merged directly because current Development already supersedes them through the shared model-context runtime, but the Python 3.13 compatibility insight is preserved here with a focused regression test.
+
+## Related Version Updates
+
+- `application/single_app/config.py` updated to `0.242.068`.

+# Chat Model Icon Avatar Fix
+
+Fixed in version: **0.242.071**
+
+## Issue Description
+
+Model endpoint icons uploaded or selected in Admin Settings were saved with endpoint model rows, but model-only chat responses still showed the default AI avatar on the chat page. After adding model avatar support, agent responses that did not carry an `agent_icon` payload could fall through to the selected model icon even though an agent identity was present.
+
+## Root Cause Analysis
+
+The multi-endpoint catalog and chat model selector already carried model icon payloads, but assistant message metadata did not persist the resolved model icon. The chat avatar renderer only checked `agent_icon` metadata before falling back to `/static/images/ai-avatar.png`, so saved model icons were not used for normal model responses.
+
+The follow-up regression happened because model-icon fallback looked only for a missing valid agent icon. Some agent response paths can include `agent_display_name` or `agent_name` while omitting `agent_icon`, so the renderer needed to treat agent identity as enough to block model-icon fallback.
+
+## Technical Details
+
+### Files Modified
+
+- `application/single_app/route_backend_chats.py`
+- `application/single_app/static/js/chat/chat-messages.js`
+- `application/single_app/config.py`
+- `functional_tests/test_chat_model_icon_avatar.py`
+- `ui_tests/test_chat_model_icon_avatar.py`
+
+### Code Changes Summary
+
+- Normalized the saved model endpoint icon from the resolved endpoint model configuration.
+- Added `model_icon` to model selection metadata, assistant message documents, streaming cancellation events, and final streaming/non-streaming response payloads.
+- Updated chat assistant avatar rendering to prefer agent icons, then model icons only for model-only responses, then the default AI avatar.
+- Added an agent-identity guard so agent responses do not use model icons when `agent_display_name`, `agent_name`, or agent selection metadata is present.
+- Added a fallback lookup from `window.chatModelOptions` so older model-only messages can render a model icon when the saved message has enough model/deployment metadata.
+- Added regression coverage for backend metadata propagation, frontend model avatar rendering, and agent-priority behavior.
+
+## Validation
+
+Validation includes:
+
+- Python compile checks for the changed backend route and tests.
+- `node --check application/single_app/static/js/chat/chat-messages.js`.
+- `functional_tests/test_chat_model_icon_avatar.py`.
+- Skip-safe Playwright coverage in `ui_tests/test_chat_model_icon_avatar.py`.
+- Existing XSS guardrail functional test.
+- Repository whitespace diff check.
+
+## Impact Analysis
+
+Model-only assistant bubbles can now show the configured model icon or uploaded model image. Agent bubbles continue to prefer configured agent icons, and agent responses without an icon fall back to the normal assistant avatar instead of being overwritten by the model icon. Legacy model-only messages without persisted model icon metadata can still render icons when the current chat model catalog can match the saved deployment metadata.

+# Azure OpenAI Model Discovery Identity Fix
+
+Fixed in version: **0.250.001**
+
+## Issue Description
+
+Legacy Azure OpenAI model discovery for GPT, embeddings, and image generation could be confusing because `Fetch Models` uses Azure Resource Manager deployment listing while runtime generation uses the Azure OpenAI data plane. Admins could successfully test embedding generation or process uploaded files with managed identity, yet still see model fetch failures when the management-plane identity did not have the correct Azure OpenAI role.
+
+## Root Cause
+
+The fetch and use paths require different authorization surfaces:
+
+- `Fetch Models` is a management-plane operation that lists Azure OpenAI deployments.
+- Embedding generation, file-upload embeddings, GPT inference, and image generation are data-plane operations.
+- API keys can authorize data-plane inference but cannot authorize management-plane deployment listing.
+
+For legacy GPT, embeddings, and image generation settings, SimpleChat uses the configured app registration/service principal for management-plane fetch and the selected runtime authentication method for data-plane use.
+
+## Technical Details
+
+Files modified:
+
+- `application/single_app/route_backend_models.py`
+- `application/single_app/templates/admin_settings.html`
+- `deployers/bicep/modules/setPermissions.bicep`
+- `deployers/bicep/modules/setPermissions-openAIExternal.bicep`
+- `deployers/bicep/main.json`
+- `deployers/azurecli/deploy-simplechat.ps1`
+- `deployers/terraform/main.tf`
+- `deployers/version.txt`
+- `functional_tests/test_azure_openai_identity_split.py`
+- `functional_tests/test_azure_openai_deployer_role_split.py`
+
+Code changes summary:
+
+- Centralized legacy Azure OpenAI account-name normalization for GPT, embedding, and image fetch routes.
+- Routed legacy Azure OpenAI deployment discovery through the configured service principal management-plane credential.
+- Added an Admin Settings setup guide explaining the management-plane fetch versus data-plane use split.
+- Added deployer role assignments so the app registration/service principal receives `Cognitive Services User` on the Azure OpenAI resource for model discovery.
+- Preserved the App Service managed identity `Cognitive Services OpenAI User` role for data-plane generation.
+
+## Role Mapping
+
+| Purpose | Entra object | Azure role | Scope |
+| --- | --- | --- | --- |
+| Fetch model deployments | SimpleChat app registration/service principal, such as `simplechat-*-ar` | `Cognitive Services User` | Azure OpenAI resource |
+| Generate embeddings or images with managed identity | App Service managed identity, such as `simplechat-*-app` | `Cognitive Services OpenAI User` | Azure OpenAI resource |
+| Generate embeddings or images with key authentication | Saved Azure OpenAI key | Resource key from Keys and Endpoint | Azure OpenAI data plane |
+
+## Validation
+
+Validation approach:
+
+- Functional tests verify the backend fetch/use identity split.
+- Functional tests verify Bicep, ARM JSON, Azure CLI, and Terraform deployer role coverage.
+- Python compile checks validate edited backend and test files.
+
+Before this fix, an admin could see a successful embedding connection test but fail to fetch embedding deployments if the management-plane principal lacked deployment discovery access. After this fix, deployers grant the explicit management-plane role and the admin guide names which identity and role apply to fetch versus use.
+
+Config version updated in `application/single_app/config.py` to **0.250.001**.

+    *   Added admin setup guidance explaining which identity is used for legacy Azure OpenAI model discovery and which identity or key is used for runtime GPT, embedding, and image generation calls.
+    *   Clarifies that `Fetch Models` uses Azure Resource Manager deployment listing while chat generation, embeddings, file-upload embedding generation, and image generation use the Azure OpenAI data plane.
+    *   (Ref: Azure OpenAI setup guide, Admin Settings model guidance, `AZURE_OPENAI_IDENTITY_SETUP_GUIDE.md`)
+
+*   **Model Endpoint Setup Guidance**
+    *   Added in-product **Setup Guide** buttons beside global, personal, and group model endpoint actions, plus inline setup guidance inside the shared Model Endpoint modal.

+    *   (Ref: governance policies, delegated item policies, Admin Settings Governance tab)
+
+*   **Governance and App Settings Cache Versioning**
+    *   Added cache-version coordination so settings and governance policy changes can invalidate stale worker process caches across Redis-enabled and non-Redis deployments.

+
+*   **Pull Request Preparation Prompt**
+    *   Added a reusable Copilot prompt for preparing SimpleChat branches for pull requests into `Development`.
+    *   The workflow verifies branch freshness against `Development`, runs repo-aligned validation checks, updates release notes when needed, and gates push or PR creation behind explicit user confirmation.
+    *   Optional merge or rebase from `Development` is supported only when requested, with conflicts resolved interactively by the agent after explaining each side of the conflict.
+    *   (Ref: `.github/prompts/prepare-for-pull-request.prompt.md`, PR readiness workflow, Development branch validation)
+
+*   **Tableau Action**

+
+*   **Workflow Per-Document Analysis and Generated Office Exports**
+    *   Added a workflow Analyze mode that runs the same prompt against each selected document separately, then combines the per-document replies, coverage, citations, generated artifacts, and alert targets into the workflow result.
+    *   Added SimpleChat action tools for generated Word documents and PowerPoint presentations, with group workflow uploads defaulting to the current group workspace while preserving existing group access checks.
+    *   (Ref: `functions_document_actions.py`, `functions_workflow_runner.py`, `functions_simplechat_operations.py`, `simplechat_plugin.py`, `WORKFLOW_PER_DOCUMENT_ANALYSIS_AND_EXPORTS.md`)
+
+*   **Group Workflows**
+    *   Added group-scoped workflows with dedicated Cosmos containers for workflow definitions, run history, and per-document run items.

+    *   Added a Group Workflows tab to group workspaces and updated the shared workflow UI/activity page to support personal and group workflow scopes.
+    *   (Ref: `functions_group_workflows.py`, `route_backend_workflows.py`, `functions_workflow_runner.py`, `group_workspaces.html`, `workspace_workflows.js`, `GROUP_WORKFLOWS.md`)
+
+*   **Voice-Assisted Form Inputs and Agent Instruction Drafting**
+    *   Added speech-to-text microphone controls to supported agent, group, public workspace, document metadata, and tag-name fields when speech input is enabled.
+    *   Added an agent Instruction Brief field and Draft Instructions action that sends typed or dictated context to the configured GPT/APIM model, then inserts editable Markdown instructions before save.
+    *   Dictated tag names are normalized to lowercase safe tag values, and dictated document keywords are normalized to comma-separated values.
+    *   (Ref: `form-voice-input.js`, `agent_modal_stepper.js`, `/api/agents/draft-instructions`, `VOICE_ASSISTED_FORM_INPUTS.md`)
+
+*   **Microsoft Graph Send Mail Action**
+    *   Microsoft Graph actions can now create manual drafts, prepare delayed-delivery drafts from 5 to 600 seconds, or send mail automatically from the signed-in user's mailbox.
+    *   Added plugin configuration for default delivery mode and delay seconds, with runtime validation and Graph scopes for draft creation, delayed draft submission, and immediate send flows.
+    *   (Ref: Microsoft Graph action, `MSGraphPlugin.send_mail`, `plugin_modal_stepper.js`, `MSGRAPH_SEND_MAIL_ACTION.md`)
+
+*   **Workspace-Backed Chat Upload Replacement**
+    *   Eligible chat uploads now use the personal workspace document as the source of truth instead of also running the legacy chat-local extraction and chat blob storage path.
+    *   Chat creates a lightweight workspace-backed file message with processing progress and automatically includes ready linked workspace documents in regular and streaming chat search context for enhanced citations.
+    *   Fixed the chat handoff queue helper to use the configured Flask executor extension, preventing orphaned personal workspace rows from remaining at queued 0% when background processing was not submitted.
+    *   (Ref: `route_frontend_chats.py`, `route_backend_chats.py`, `functions_documents.py`, `CHAT_UPLOAD_PERSONAL_WORKSPACE_HANDOFF.md`)
+
+*   **Chat Upload Personal Workspace Handoff**
+    *   Eligible chat uploads now queue a personal workspace document while preserving the existing chat attachment/image message behavior and fallback flow.
+    *   Chat-uploaded workspace documents receive the `conversations` tag plus the conversation ID tag, store explicit source metadata, and surface processing progress in the chat message with the same document status fields used by workspace uploads.
+    *   Workspace metadata and delete flows now show when a document is linked to a conversation.
+    *   (Ref: `route_frontend_chats.py`, `functions_documents.py`, `workspace-documents.js`, `chat-messages.js`, `CHAT_UPLOAD_PERSONAL_WORKSPACE_HANDOFF.md`)
+
+*   **Chat Upload Personal Workspace Handoff Design**
+    *   Added a proposed implementation plan for routing eligible chat file uploads into the user's personal workspace while preserving the existing chat attachment experience and fallback flow.
+    *   Documented the recommended metadata, conversation tags, delete lifecycle, search/analyze/compare implications, security checks, failure modes, testing plan, and staged rollout for the handoff.
+    *   (Ref: `CHAT_UPLOAD_PERSONAL_WORKSPACE_HANDOFF.md`, chat uploads, personal workspace documents, conversation-linked document lifecycle)
+
+*   **Document Intelligence Auto Mode and PDF Reprocessing**
+    *   Added **Auto** extraction for PDFs and images so admins can sample the first PDF pages with Layout and let SimpleChat finish with Read or Layout based on detected tables or selection marks.
+    *   Expanded Search & Extract guidance with a Read/Layout/Auto help modal, Auto sample-page control, and clearer Layout benefit/cost copy including the 6X increase for every 1000 pages.
+    *   Added Read/Layout extraction badges plus single-document and bulk PDF reprocess actions in personal, group, and public workspaces. New PDF/image uploads preserve their source blob so PDFs can be reprocessed later when available.
+    *   (Ref: `DOCUMENT_INTELLIGENCE_PDF_IMAGE_EXTRACTION_MODE.md`, `functions_documents.py`, Admin Settings Search & Extract, workspace document actions)
+
+*   **Cosmos Native Autoscale Conversion**
+    *   Added global and per-container policy controls that let admins convert dedicated manual Cosmos throughput to native Cosmos autoscale.
+    *   Added manual Convert actions for database and container throughput so admins can move eligible manual throughput to autoscale from the Admin Settings Scale tab.
+    *   Background throughput automation can now prioritize eligible manual-to-autoscale conversions before utilization-based RU scale decisions, while preserving configured min and max guardrails.
+    *   (Ref: `functions_cosmos_throughput.py`, Admin Settings Scale tab, `COSMOS_NATIVE_AUTOSCALE_CONVERSION.md`)
+
+*   **Document Intelligence PDF and Image Extraction Mode**
+    *   Added a Search & Extract admin setting that lets administrators choose Read or Layout extraction for PDF and image uploads.
+    *   Read keeps the faster text-extraction path, while Layout captures richer structure such as tables, document layout, and checked or unchecked selection marks with some added parsing latency.
+    *   New PDF and image ingestion records `document_intelligence_extraction_mode` metadata so extracted documents identify whether Read or Layout was used.
+    *   (Ref: `admin_settings.html`, `functions_content.py`, `functions_documents.py`, `DOCUMENT_INTELLIGENCE_PDF_IMAGE_EXTRACTION_MODE.md`)
+
+*   **Cosmos Container Policy Enforcement**
+    *   Added an Admin Settings option to enforce the global Cosmos throughput automation policy across every dedicated-throughput container.
+    *   New containers discovered by Refresh or the background autoscale loop inherit the same global thresholds, intervals, RU step sizes, and guardrails automatically.
+    *   Added an Apply Global Policy action in the Containers modal to stage the current global policy onto all currently discovered containers while preserving per-container cooldown timestamps.
+    *   (Ref: `functions_cosmos_throughput.py`, `admin_settings.html`, `admin_settings.js`, `COSMOS_CONTAINER_POLICY_ENFORCEMENT.md`)
+
+*   **Cosmos DB Throughput Autoscale Controls**
+    *   Added Cosmos DB RU monitoring to the Admin Settings Scale tab, including database throughput status, recent normalized RU utilization, and per-container request-unit visibility.
+    *   Added guarded manual Scale Up and Scale Down actions plus optional background automation with separate up/down thresholds, intervals, RU step sizes, and minimum/maximum guardrails.
+    *   Added deployment metadata app settings and a custom Cosmos throughput operator role so the app identity can adjust throughput and read metrics without exposing Cosmos data-plane access to agents or user actions.
+    *   (Ref: `functions_cosmos_throughput.py`, Admin Settings Scale tab, Cosmos throughput autoscale, `COSMOS_THROUGHPUT_AUTOSCALE.md`)
+
+*   **Workflow File Sync Triggers and Batch Resume**
+    *   Added File Sync Before Run controls so workflows can trigger selected personal, group, or public File Sync sources before the workflow prompt executes.
+    *   Added Monitor File Sync Changes mode, which checks selected sync sources on the configured interval and only runs the workflow when new or changed files are detected.
+    *   Added dynamic Analyze targeting for changed synced documents, per-document workflow run item tracking, and a Resume failed action that reruns failed document items from a previous Analyze workflow run.
+    *   (Ref: `functions_personal_workflows.py`, `functions_workflow_runner.py`, `functions_file_sync.py`, `route_backend_workflows.py`, `workspace_workflows.js`, `WORKFLOW_FILE_SYNC_TRIGGERS.md`)
+
+*   **OneDrive File Sync and Source Selection UX**
+    *   Added OneDrive as a personal-workspace File Sync source that pulls selected OneDrive files and folders into the existing SimpleChat document processing, chunking, embedding, and Azure AI Search indexing pipeline.
+    *   Added provider browsing and selected folder/file controls so users can sync the source root, specific folders, or specific files, with Include subfolders moved into the source-selection and filter workflow.
+    *   Added remote change-token handling for provider-native IDs and eTags/cTags before content checksum fallback, improving change detection for cloud-drive files.
+    *   (Ref: `functions_file_sync.py`, `route_backend_file_sync.py`, `workspace-file-sync.js`, `ONEDRIVE_FILE_SYNC.md`, `test_file_sync_onedrive_personal.py`)
+
+*   **Global Cloud Drive Connector Identities**
+    *   Extended global workspace identities so admins can manage File Sync cloud-drive connector credentials separately from personal user sync choices.
+    *   OneDrive File Sync now resolves an admin-managed global File Sync client-secret identity before falling back to legacy app registration configuration, keeping tenant-level Graph credentials out of the personal source setup flow.
+    *   Updated Admin Settings and workspace identity UI guidance to clarify that users choose what to sync while admins own tenant cloud-drive connector permissions.
+    *   (Ref: `functions_workspace_identities.py`, `functions_file_sync.py`, `workspace-identities.js`, `admin_settings.html`, `WORKSPACE_IDENTITIES.md`)
+
+*   **Azure Files File Sync Source**
+    *   Added Azure Files as a first-class File Sync source type so workspaces can sync from Azure Storage file shares using a file service URL, share name, and optional directory path.
+    *   Added Azure Files-compatible reusable identity support for managed identity, service principal client secret, and storage connection string authentication while keeping SMB sources on username/password or anonymous authentication.
+    *   Updated File Sync source selection, admin source-type visibility controls, synced-document badges, documentation, and regression coverage for the new Azure Files connector.
+    *   (Ref: `functions_file_sync.py`, `functions_workspace_identities.py`, `workspace-file-sync.js`, `workspace-identities.js`, `AZURE_FILES_FILE_SYNC.md`, `test_file_sync_azure_files_identity.py`)
+
+*   **Conversation Feed Pagination**
+    *   Added a paged conversation feed so chat startup loads pinned conversations, unread conversations, and the first 20 recent conversations instead of pulling every accessible conversation into the browser.
+    *   Added load-more and near-bottom scroll loading for both the main conversation list and docked sidebar, with backend-driven title search that is not limited to the currently loaded page.
+    *   Hidden conversations are excluded from the default feed and reloaded only when users enable the hidden-conversation toggle.
+    *   (Ref: `route_backend_conversations.py`, `functions_conversation_feed.py`, `chat-conversations.js`, `chat-sidebar-conversations.js`, `CONVERSATION_FEED_PAGINATION.md`)
+
+*   **Group File Share Approval Notifications**
+    *   Added notifications when personal and group documents are shared, approved, or denied so recipients know when a file needs review and share owners know the outcome.
+    *   Group document shares now require approval by the receiving group's Owners, Admins, or Document Managers before the file becomes searchable in that group.
+    *   Receiving groups now see Approve or Remove actions for shared files, cannot delete the owner group's document, and cannot view the owner group's shared-recipient list.
+    *   (Ref: group document sharing approval, `route_backend_group_documents.py`, `route_backend_documents.py`, `functions_notifications.py`, `group_workspaces.html`, `GROUP_FILE_SHARE_APPROVAL_NOTIFICATIONS.md`)
+
+*   **Stats Time Windows and CSV Exports**
+    *   Added 7-day, 30-day, 90-day, and custom date windows to personal profile stats, group stats, and public workspace stats so these pages match the Control Center activity-trends experience.
+    *   Added CSV export actions for personal, group, and public stats with selectable metric sections and matching predefined or custom export windows.
+    *   Centralized stats window parsing and daily bucket generation for consistent labels, chart ranges, and backend filtering across all three stats surfaces.
+    *   (Ref: profile stats, group stats, public workspace stats, `functions_stats_windows.py`, `route_frontend_profile.py`, `route_backend_groups.py`, `route_backend_public_workspaces.py`)
+
+*   **Personal Workflow Access Governance**
+    *   Added a dedicated Admin Settings Workflow section so personal workflows can be explicitly enabled or disabled.
+    *   Added optional `WorkflowUser` Enterprise App role enforcement for workflow UI access, API routes, manual runs, activity views, and SimpleChat workflow creation operations.
+    *   Added `WorkflowUser` app role definitions to Azure CLI and Terraform deployer assets, with deployer version tracking updated.
+    *   (Ref: workflow access control, `functions_settings.py`, `route_backend_workflows.py`, `route_frontend_admin_settings.py`, `PERSONAL_WORKFLOWS.md`, `WORKFLOW_ACCESS_CONTROL_FIX.md`)
+
+*   **Azure Commercial Databricks Action**
+    *   Added a first-class Databricks action type for Azure Commercial workspaces, using the Databricks SQL Statement Execution API rather than an ODBC driver.
+    *   Added action modal configuration for workspace URL, SQL Warehouse ID, catalog/schema defaults, token/service-principal/managed-identity auth, execution limits, and reusable identity selection.
+    *   Added read-only SQL enforcement, factory-based Semantic Kernel loading, manifest validation, schemas, feature documentation, and functional/UI coverage.
+    *   (Ref: `DatabricksPlugin`, `DatabricksPluginFactory`, Databricks action modal, `DATABRICKS_ACTION_CONFIGURATION.md`)
+
+*   **Model Context Protocol Actions**
+    *   Added first-class MCP action support with transport, authentication, timeout, tool allowlist, and cached tool metadata configuration in the shared action modal.
+    *   Added server-side MCP tool discovery plus runtime tool invocation through Semantic Kernel's MCP connector, including dynamic tool function registration for agents.
+    *   Restricted stdio MCP transport to admin-managed global actions because it launches server-side commands, while remote transports support streamable HTTP, SSE, and WebSocket.
+    *   (Ref: MCP actions, Semantic Kernel MCP connector, `functions_mcp_operations.py`, `mcp_plugin.py`, `mcp_plugin_factory.py`, `route_backend_plugins.py`, `plugin_modal_stepper.js`, `MCP_ACTION_CONFIGURATION.md`)
+
+*   **Layered Message Masking**
+    *   Added mask-plus and mask-minus controls so users can add multiple selected-text masks to the same chat message.
+    *   Full-message masks now layer independently from selected-text masks, allowing users to remove the full-message mask while preserving prior selected ranges.
+    *   Extended masking support to collaborative personal and group conversations, including shared event updates and source-message metadata sync.
+    *   (Ref: message masking, collaborative conversations, `functions_message_masking.py`, `route_backend_chats.py`, `route_backend_collaboration.py`, `chat-messages.js`, `chat-collaboration.js`)
+
+*   **Workspace and Global Identities**
+    *   Promoted reusable identities into first-class personal, group, and public workspace tabs instead of managing them from the File Sync source list.
+    *   Added an admin-managed Global Identities tab for credentials shared by global agents, actions/plugins, model endpoints, and future global integrations.
+    *   Added a dedicated global identity Cosmos DB container while keeping public workspace identities limited to File Sync usage and excluding File Sync from global identities.
+    *   (Ref: workspace identities, global identities, `functions_workspace_identities.py`, `route_backend_workspace_identities.py`, `workspace-identities.js`, `_sidebar_nav.html`)
+
+*   **Visio Ingestion and Citation Previews**
+    *   Added native `.vsdx` upload support that parses Visio package XML and indexes each diagram page as a structured searchable chunk.
+    *   Enhanced citations now render a lightweight PNG preview for the cited Visio page and keep the original `.vsdx` available for download.
+    *   Added functional and UI coverage for Visio parsing, preview rendering, and chat citation modal behavior.
+    *   (Ref: Visio ingestion, enhanced citations, `functions_visio.py`, `functions_documents.py`, `route_enhanced_citations.py`, `chat-enhanced-citations.js`, `test_visio_ingestion_preview.py`, `VISIO_INGESTION.md`)
+
+*   **Outlook MSG File Ingestion**
+    *   Added support for Outlook `.msg` files so saved email messages can be uploaded into workspaces and participate in document processing, metadata extraction, chunking, search, and chat grounding.
+    *   Email files now fit the same workspace knowledge workflow as other supported business documents, helping users bring message-based context into conversations without manually copying mail content.
+    *   (Ref: Outlook MSG ingestion, workspace uploads, document processing, `functions_content.py`, `functions_documents.py`)
+
+*   **Assigned Knowledge for Agents**
+    *   Added agent-level Assigned Knowledge so agent creators can bind agents to governed workspace sources, documents, and tags.
+    *   Chat now resolves the selected agent from trusted server-side records and enforces its assigned search scope for both regular and streaming chat, including personal, group, and public workspace boundaries.
+    *   When an Assigned Knowledge agent is selected in chat, document search is forced on and the workspace, document, and tag controls become read-only while displaying the agent's configured knowledge context.
+    *   (Ref: Assigned Knowledge, agent modal Knowledge step, chat document search enforcement, `functions_assigned_knowledge.py`, `route_backend_agents.py`, `route_backend_chats.py`, `agent_modal_stepper.js`, `chat-agents.js`, `chat-documents.js`)
+
+*   **Deep Research Distroless JavaScript Rendering Runtime**
+    *   Added Playwright Chromium packaging for the existing Azure Linux distroless app image so Deep Research can optionally render JavaScript-heavy source pages without changing the final container base image.
+    *   Added a runtime capability check that verifies Chromium launch support and surfaces the status in Admin Settings before admins rely on rendered-page fallback.
+    *   Kept Chromium sandboxing enabled by default, added an explicit `SOURCE_REVIEW_CHROMIUM_NO_SANDBOX` escape hatch for reviewed deployments, and capped rendered fetch concurrency with `SOURCE_REVIEW_JS_RENDER_MAX_CONCURRENCY`.
+    *   (Ref: Deep Research JavaScript rendering, distroless container runtime, `Dockerfile`, `requirements.txt`, `functions_source_review.py`, `admin_settings.html`)
+
+*   **Source Review Load More Support**
+    *   Source Review can now use the optional rendered-page path to click visible Load More, Show More, View More, and related archive controls on source pages before extracting links and evidence.
+    *   Load More clicks are bounded by a configurable admin cap, stop early when no new content appears, and can stop when requested date-range evidence is visible for prompts such as past three years.
+    *   Existing SSRF, redirect, timeout, page-budget, and content-type protections remain enforced.
+    *   (Ref: Source Review Load More, `functions_source_review.py`, `admin_settings.html`, `test_source_review_security.py`)
+
+*   **Source Review Model-Assisted Link Planning**
+    *   Deep Source Review can now ask the selected chat model to rank server-extracted child links before additional source pages are fetched, improving general multi-source research without adding question-specific heuristics.
+    *   The planner is bounded to already extracted, policy-approved candidate URLs; invented URLs are ignored and deterministic ordering remains the fallback.
+    *   Added admin control for enabling model-assisted link planning and functional coverage for candidate validation and planner-driven ordering.
+    *   (Ref: Deep Source Review, Source Review link planning, `functions_source_review.py`, `route_backend_chats.py`, `admin_settings.html`, `test_source_review_deep_traversal.py`)
+
+*   **File Sync for Workspace Documents**
+    *   Added an optional SMB-based File Sync capability for personal, group, and public workspaces, with scope-specific enablement, allow/block controls, and Redis readiness gating before sync can be enabled.
+    *   Sync sources support UNC paths, credentials with optional Azure Key Vault storage, fixed and parent-folder-derived tags, include/exclude filters, file type filters, manual runs, scheduled runs, history, counts, and debug logging.
+    *   Synced remote file changes reuse the existing same-name document upload behavior to create document versions, and synced-document deletes now ask whether to delete locally only or ignore the remote path for future runs.
+    *   Added Control Center activity-log support for File Sync events and admin warnings for scale and performance considerations.
+    *   (Ref: File Sync, SMB sync sources, workspace Sync tab, `functions_file_sync.py`, `route_backend_file_sync.py`, `workspace-file-sync.js`, `test_file_sync_capability.py`, `FILE_SYNC.md`)
+
+*   **Source Review for Web Evidence**
+    *   Added an optional chat **Sources** toggle that reviews source pages from pasted URLs and Web Search citations before the final model response is generated.
+    *   Deep Source Review can follow a bounded set of relevant links from source indexes while enforcing SSRF protections, redirect/page-size/time limits, robots.txt handling, and prompt-injection isolation for fetched page text.
+    *   Added admin controls for Source Review defaults, page budgets, domain/user allowlists and blocklists, optional JavaScript rendering fallback, and audit logging.
+    *   (Ref: Source Review, `functions_source_review.py`, `route_backend_chats.py`, `admin_settings.html`, `chats.html`, `test_source_review_security.py`, `SOURCE_REVIEW.md`)
+
+*   **Conversation Charts and Workflow Tabular Reuse**
+    *   Added chart creation as a core conversation ability so users can request inline charts directly in chat while agents and workflows can still use assigned chart actions.
+    *   Added a reusable tabular analysis import surface for workflow document analysis and comparison, reducing workflow coupling to the chat route while preserving existing chat tabular behavior.
+    *   Enabled Semantic Kernel auto tool invocation in the model-only fallback path so core conversation tools can be called when chart requests are routed through the kernel.
+    *   (Ref: conversation charts, workflow tabular analysis, `semantic_kernel_loader.py`, `route_backend_chats.py`, `functions_tabular_analysis.py`, `functions_workflow_runner.py`, `test_conversation_chart_and_tabular_reuse.py`)
+
+*   **Generated Markdown Artifact Viewer**
+    *   Added a `View MD` action beside `Download MD` on generated Markdown artifact cards so users can inspect rendered Markdown directly in Chats before downloading the file.
+    *   Reused the citation modal for the rendered view and improved Markdown citation handling so `.md` and `.markdown` citations display as sanitized rendered Markdown instead of raw source text.
+    *   Added UI regression coverage for rendered previews, rendered artifact modal content, and unsafe attribute stripping.
+    *   (Ref: generated Markdown artifacts, citation modal Markdown rendering, `chat-messages.js`, `chat-citations.js`, `test_chat_generated_tabular_output_card.py`, `GENERATED_ARTIFACT_MARKDOWN_VIEW.md`)
+
+*   **Tabular Related Document Evidence**
+    *   Added generic row-level related-document resolution for workspace tabular analysis, so when a CSV or workbook row explicitly references a supporting non-tabular file, the tabular path can pull excerpts from that document and use them alongside the computed row results.
+    *   Related document evidence now flows into both the outer tabular handoff and generated structured exports, which helps responses use supporting file context without treating those files as isolated search-only results.
+    *   Added focused regression coverage and versioned feature documentation for the related-document matching, evidence summary, and export prompt wiring.
+    *   (Ref: tabular related-document evidence, `route_backend_chats.py`, `functions_search_service.py`, `test_tabular_related_document_evidence.py`, `test_tabular_computed_results_prompt_priority.py`, `test_tabular_generated_output_exports.py`, `TABULAR_RELATED_DOCUMENT_EVIDENCE.md`)
+
+*   **Generated Artifact Workspace Promotion Approval**
+    *   Added an `Add to Workspace` action to generated analysis artifact cards in Chats so users can move reusable exports out of the conversation and into workspace documents.
+    *   Personal promotions now queue immediately, while group and public promotions create a visible pending workspace file that must be approved before it becomes usable for search and chat.
+    *   Group and public workspace document lists now show an `Approve` action for pending generated artifacts, and the requester receives approval workflow notifications as the file moves through review and processing.
+    *   (Ref: generated artifact promotion, `route_enhanced_citations.py`, `route_backend_group_documents.py`, `route_backend_public_documents.py`, `chat-messages.js`, `group_workspaces.html`, `public_workspace.js`, `test_generated_artifact_workspace_promotion.py`, `test_chat_generated_tabular_output_card.py`)
+
+*   **Chat Clipboard Paste Uploads**
+    *   Added direct clipboard upload support in Chats so users can paste copied images and browser-exposed files straight into the main chat message box instead of opening the file picker first.
+    *   The pasted upload flow now reuses the existing chat upload pipeline, including automatic conversation creation, upload consent checks, and backend file processing.
+    *   Clipboard files with empty names are normalized before upload so pasted screenshots still reach the existing extension-based processing path.
+    *   (Ref: chat paste uploads, `chat-input-actions.js`, `test_chat_clipboard_paste_upload_support.py`, `test_chat_clipboard_paste_upload_workflow.py`, `CHAT_CLIPBOARD_PASTE_UPLOADS.md`)
+
+*   **Staging Branch UI Test CI/CD**
+    *   Added a protected GitHub Actions workflow for the `Staging` branch that deploys the Azure Developer CLI staging environment, waits for App Service warm-up, and runs live UI smoke coverage before the environment is considered healthy.
+    *   Added a reusable staging bootstrap script for GitHub OIDC app registration, federated credentials, Azure role assignments, GitHub Environment variables, App Service CI authentication settings, and Microsoft Playwright Workspace wiring.
+    *   (Ref: `.github/workflows/staging-azd-ui-tests.yml`, `deployers/Initialize-GitHubActionsStaging.ps1`, `docs/explanation/features/v0.241.014/STAGING_UI_CICD.md`, `test_staging_ui_cicd_workflow.py`)
+
+*   **Microsoft Playwright Workspaces Staging Runner**
+    *   Added Azure-hosted Playwright Workspace support for staging smoke tests, including Node-based Playwright service execution and matching Python smoke coverage for the staging chat experience.
+    *   (Ref: `ui_tests/playwright-workspaces/`, `ui_tests/test_staging_chat_smoke.py`, `PLAYWRIGHT_SERVICE_URL`)
+
+*   **Service Principal Authentication for CI UI Tests**
+    *   Added a disabled-by-default `/ci-auth/session` endpoint so staging UI tests can create a Flask session from a fresh Entra access token minted by the GitHub OIDC service principal.
+    *   (Ref: `functions_authentication.py`, `route_frontend_authentication.py`, `config.py`, `appRegistrationRoles.json`, `SIMPLECHAT_UI_AUTH_RESOURCE`, `ENABLE_CI_BEARER_SESSION_AUTH`)
+
+*   **Profile Sidebar Toggle Style Preference**
+    *   Added a profile navigation preference for large versus compact sidebar hide controls and applied it across full and compact sidebar templates.
+    *   (Ref: `profile.html`, `_sidebar_nav.html`, `_sidebar_short_nav.html`, `sidebar.css`, `route_backend_users.py`, `test_profile_sidebar_toggle_style_preference.py`)
+
+#### Bug Fixes
 
-*   **Uploaded File Preview Body XSS Hardening**
+*   **Azure OpenAI Model Discovery Identity Split**
+    *   Legacy GPT, embedding, and image `Fetch Models` routes now use the configured app registration/service principal management-plane credential for Azure OpenAI deployment discovery instead of implicitly following runtime data-plane managed identity behavior.
+    *   Deployer assets now grant the app registration/service principal `Cognitive Services User` for model discovery while preserving the App Service managed identity `Cognitive Services OpenAI User` role for data-plane inference.
+    *   (Ref: `route_backend_models.py`, deployer OpenAI RBAC, `AZURE_OPENAI_MODEL_DISCOVERY_IDENTITY_FIX.md`)
+
+*   **Chat Model Icon Avatars**
+    *   Fixed saved model endpoint icons and uploaded model images not appearing on model-only assistant responses in chat.
+    *   Model icon metadata now flows through multi-endpoint model resolution, streaming and non-streaming response metadata, and assistant avatar rendering for model-only responses.
+    *   Preserved agent avatar priority so agent responses never fall through to the model icon when an agent identity is present.
+    *   (Ref: chat assistant avatars, model endpoint icons, `route_backend_chats.py`, `chat-messages.js`)
+
+*   **Tabular SK Python 3.13 Kernel Parameter Compatibility**
+    *   Updated public tabular `@kernel_function` parameters to avoid `Annotated[Optional[str], ...]` so Semantic Kernel argument parsing works on both Python 3.12 and Python 3.13.
+    *   Added a guardrail test that fails if optional string annotations are reintroduced on public tabular tool parameters.
+    *   Preserved current Development model-context routing instead of reintroducing older endpoint-specific route wiring.
+    *   Inspired by and adapted from PR #892 by @vivche.
+    *   (Ref: Python 3.13, Semantic Kernel tool parsing, tabular SK parameters, `test_tabular_kernel_parameter_annotations.py`)
+
+*   **Python 3.12 CI and XSS Guardrail Fix**
+    *   Updated GitHub workflow Python setup from 3.11 to 3.12 to match the supported SimpleChat runtime and prevent valid Python 3.12 f-string syntax from failing CI parse checks.
+    *   Reworked changed Admin Settings, group workspace delete modal, and profile hero rendering paths to satisfy the XSS sink guardrail without broad suppressions.
+    *   (Ref: Python 3.12 CI, XSS sink validation, Admin Settings bootstrap data, group workspace delete modal, profile hero image)
+
+*   **PR Readiness Guardrail Cleanup**
+    *   Fixed pull-request validation blockers by removing trailing whitespace, dropping an unnecessary `|safe` filter from JSON-rendered Admin Settings version data, removing a UTF-8 BOM from the Semantic Kernel loader, and documenting reviewed plugin authorization boundaries for the BAC guardrail.
+    *   Keeps the beta branch aligned with SimpleChat PR hygiene, XSS, route, and broken-access-control validation before draft PR creation.
+    *   (Ref: PR readiness, `check_xss_sinks.py`, `check_broken_access_control.py`, Semantic Kernel plugins)
+
+*   **Governance Admin Rendering XSS Hardening**
+    *   Reworked changed admin governance, model endpoint, agent, and plugin table rendering paths so untrusted names, descriptions, IDs, and labels are populated with DOM APIs and `textContent` instead of interpolated HTML attributes.
+    *   Added narrow reviewed XSS guardrail suppressions only for static Bootstrap modal shells that do not interpolate untrusted values.
+    *   (Ref: governance admin UI, model endpoint table, plugin table rendering, XSS sink validation)
+
+*   **Group Workflow Assignment Cleanup**
+    *   Fixed Admin Settings form bloat caused by malformed nested JSON strings being saved as group workflow assignment IDs.
+    *   Group workflow assignment settings now preserve valid group UUIDs, drop invalid payload fragments, and compact the hidden admin form field before save.
+    *   (Ref: `functions_settings.py`, `admin_settings.js`, `GROUP_WORKFLOW_ASSIGNMENT_CLEANUP_FIX.md`)
+
+*   **Workflow Activity New-Tab Navigation**
+    *   Fixed workflow `Activity` actions so they no longer navigate the current workspace tab after opening the activity view in a new tab.
+    *   Blocked pop-ups now show a warning toast instead of replacing the workflow list page.
+    *   (Ref: `workspace_workflows.js`, workflow Activity button, `WORKFLOW_ACTIVITY_CURRENT_TAB_NAVIGATION_FIX.md`)
+
+*   **Group Workflow Activity View Gate**
+    *   Fixed group workflow activity links so the shared `/workflow-activity` page no longer depends on the personal workflow feature flag when opened with `scope=group`.
+    *   Group activity views now use group-specific authorization, including group workspaces enabled, group workflows enabled, group assignment gating, and current group membership validation.
+    *   Personal workflow activity links still use the existing personal workflow and WorkflowUser app-role policy.
+    *   (Ref: `route_frontend_chats.py`, `workflow-activity.js`, `GROUP_WORKFLOW_ACTIVITY_VIEW_GATE_FIX.md`)
+
+*   **Tabular Inline Chart Handoff**
+    *   Fixed tabular analysis chart requests so successful grouped CSV/XLSX results now produce SimpleChat inline chart citations instead of relying on the model to emit supported chart syntax.
+    *   Workspace-search and chat-uploaded tabular results now share the same deterministic chart handoff in both streaming and non-streaming responses, preventing unsupported Mermaid chart blocks from appearing when users request charts.
+    *   (Ref: `route_backend_chats.py`, `functions_chart_operations.py`, `test_tabular_inline_chart_handoff.py`, `TABULAR_INLINE_CHART_HANDOFF_FIX.md`)
+
+*   **Document Intelligence Upload Normalizer Import**
+    *   Fixed Azure Document Intelligence upload processing so the shared extractor resolves the extraction-mode normalizer through the existing settings module import, preventing Read/Layout/Auto uploads from failing with a missing normalizer name while avoiding the startup circular import path.
+    *   (Ref: `functions_content.py`, Document Intelligence extraction mode)
+
+*   **Cosmos Native Autoscale Migration Action**
+    *   Fixed manual-to-autoscale conversions so manual Cosmos throughput offers call the ARM `migrateToAutoscale` action instead of attempting to write `autoscaleSettings.maxThroughput` directly onto a manual offer.
+    *   Preserved the existing `PUT autoscaleSettings.maxThroughput` path for database or container throughput that is already in autoscale mode.
+    *   Expanded the least-privilege Cosmos throughput operator role with the `migrateToAutoscale/action` and operation-result read permissions required for native conversion without Cosmos data-plane access.
+    *   (Ref: `functions_cosmos_throughput.py`, `setPermissions.bicep`, `COSMOS_NATIVE_AUTOSCALE_MIGRATION_ACTION_FIX.md`)
+
+*   **Cosmos Autoscale Background Cadence**
+    *   Updated the Cosmos throughput background scheduler so the check cadence follows the configured Metrics Window instead of a hard-coded five-minute sleep.
+    *   Added background-specific autoscale start, completion, and sleep logs so scheduler runs are distinguishable from manual Admin Settings Refresh requests.
+    *   Clarified Admin Settings copy that background automation refreshes on the Metrics Window cadence while Scale Up/Down intervals remain cooldowns after scaling.
+    *   (Ref: `background_tasks.py`, `functions_cosmos_throughput.py`, Admin Settings Scale tab, `COSMOS_AUTOSCALE_BACKGROUND_CADENCE_FIX.md`)
+
+*   **Cosmos Container Metrics REST Metadata Parsing**
+    *   Switched Cosmos throughput metric collection from the Azure Monitor Query SDK response model to the raw Azure Monitor Metrics REST response for this feature, because the SDK returned container-split time series without usable metadata names or values.
+    *   Restored per-container RU utilization and request-unit rows by parsing REST `collectionname` and `databasename` metadata from the same metric dimensions shown in Azure Metrics Explorer.
+    *   (Ref: `functions_cosmos_throughput.py`, Azure Monitor Metrics REST, Cosmos `CollectionName` dimensions, `COSMOS_CONTAINER_METRICS_REST_METADATA_FIX.md`)
+
+*   **Cosmos Container Autoscale Metric Accuracy and Refresh Performance**
+    *   Tightened the Azure Monitor query so container-targeted scaling requests `NormalizedRUConsumption` split by the configured database and `CollectionName`, matching the per-container view available in the Azure portal.
+    *   Container autoscale now explicitly waits for per-container utilization rows instead of treating aggregate account-level utilization as eligible input for individual container scaling.
+    *   Reduced Admin Settings refresh latency by reusing one ARM token and reading per-container throughput settings in a bounded parallel scan instead of serial per-container reads.
+    *   (Ref: `functions_cosmos_throughput.py`, Cosmos throughput Azure Monitor dimensions, ARM container throughput reads, `COSMOS_CONTAINER_THROUGHPUT_REFRESH_PERFORMANCE_FIX.md`)
+
+*   **Cosmos Container Metric Dimensions**
+    *   Fixed Cosmos throughput status refreshes so Azure Monitor is asked for per-container metric dimensions instead of only aggregate account-level RU metrics.
+    *   Preserved the aggregate RU utilization card through a fallback query when container-dimensional metrics are delayed or unavailable, and added clearer Admin Settings messaging for that aggregate-only state.
+    *   (Ref: `functions_cosmos_throughput.py`, `admin_settings.js`, Cosmos throughput Azure Monitor metrics, `COSMOS_CONTAINER_METRICS_DIMENSION_FIX.md`)
+
+*   **Cosmos Throughput Cached Status**
+    *   Fixed the Admin Settings Cosmos throughput card so it renders the last saved database or container-targeted view immediately after server restart instead of requiring a manual Refresh to rediscover containers.
+    *   Manual Refresh and background autoscale checks now persist a compact cached status with capacity scope, throughput summary, metrics, container rows, and timestamps.
+    *   Added copy clarifying that background automation checks throughput about every 5 minutes while enabled, and versioned the Admin Settings JavaScript asset to avoid stale browser-side Cosmos UI logic.
+    *   (Ref: `functions_cosmos_throughput.py`, `admin_settings.html`, `admin_settings.js`, `COSMOS_THROUGHPUT_CACHED_STATUS_FIX.md`)
+
+*   **Container Policy Save Button Activation**
+    *   Fixed the Cosmos throughput container policy modal so saving staged container policies enables the main Admin Settings Save button immediately.
+    *   The modal now uses the standard admin form dirty-state handler instead of setting only the internal modified flag.
+    *   (Ref: `admin_settings.js`, Admin Settings Scale tab, `COSMOS_CONTAINER_POLICY_SAVE_BUTTON_FIX.md`)
+
+*   **Cosmos Throughput Refresh Logging**
+    *   Added backend start, completion, failure, and phase timing logs for Admin Settings Cosmos throughput refreshes so admins can see whether the request is waiting on token acquisition, ARM throughput reads, container scans, or Azure Monitor metrics.
+    *   Added a refresh correlation ID across route, ARM, container, and metrics logs to make a single Refresh click traceable in console logs and Application Insights.
+    *   (Ref: `functions_cosmos_throughput.py`, `route_backend_settings.py`, Cosmos throughput refresh diagnostics)
+
+*   **Advanced Conversation Search Matching**
+    *   Fixed the Advanced Search modal so it searches conversation titles and message content across both legacy and collaborative conversation stores.
+    *   Added explicit match modes for partial text, all words, any word, and whole word searches, with partial matching as the default so terms such as `Chase` can match larger tokens like `JPMorganChase`.
+    *   Normalized chat type filters so personal and multi-user conversation types are not silently excluded from advanced search results.
+    *   (Ref: advanced conversation search, chat search modal, `route_backend_conversations.py`, `chat-search-modal.js`, `ADVANCED_CONVERSATION_SEARCH_FIX.md`)
+
+*   **Visio Connector and Arc Fidelity**
+    *   Improved Visio citation previews by approximating `RelEllipticalArcTo` geometry as smooth curves instead of straight endpoint segments.
+    *   Removed duplicate fallback center-to-center connection lines when explicit connector geometry is already available, reducing visual clutter through service icons.
+    *   Added bounded supersampling to smooth rendered PNG previews while avoiding external office-suite dependencies.
+    *   Added regression coverage for curved master stencil geometry in the preview parser path.
+    *   (Ref: Visio arc geometry, connector rendering, master stencil preview expansion, `functions_visio.py`, `test_visio_ingestion_preview.py`)
+
+*   **Visio Path and Master Geometry Rendering**
+    *   Improved the built-in Visio citation preview renderer to draw supported VSDX geometry rows as actual local paths instead of collapsing those shapes to generic rectangles.
+    *   Added preview-only expansion of referenced master stencil geometry so common Azure/service icons render with more recognizable vector structure while indexed Visio chunks stay focused on page content.
+    *   Improved label placement for icon-backed shapes and dashed container labels using the Visio-exported SVG/PDF reference fixtures.
+    *   Added regression coverage to ensure preview master expansion does not pollute default ingestion parsing.
+    *   (Ref: Visio path geometry, master stencil geometry, structural renderer, `functions_visio.py`, `test_visio_ingestion_preview.py`, `architecture.svg`, `architecture.pdf`)
+
+*   **Visio Preview Runtime Simplification**
+    *   Removed the optional LibreOffice conversion branch from Visio citation previews after confirming Azure Linux `tdnf` does not provide LibreOffice packages in the app builder image.
+    *   Visio previews now consistently use the built-in structural renderer with nested shape coordinates, connector endpoint lines, supported embedded media, and page geometry.
+    *   (Ref: Visio previews, structural renderer, `functions_visio.py`, `VISIO_PREVIEW_FIDELITY_FIX.md`)
+
+*   **Visio Citation Preview Fidelity**
+    *   Strengthened the built-in Visio renderer so it preserves nested shape coordinates, connector endpoint lines, supported embedded media, and page geometry more accurately.
+    *   (Ref: Visio previews, structural rendering, `functions_visio.py`, `VISIO_PREVIEW_FIDELITY_FIX.md`)
+
+*   **Source Review Citation Seeding and Second-Hop Traversal**
+    *   Source Review now receives the full Foundry web-search citation set, not only URLs that appeared in the web-search answer text, so official sources returned as raw citations can be reviewed directly.
+    *   Added a configurable seed-page budget so initial search-result pages cannot consume the entire Source Review page budget before child source pages are inspected.
+    *   Raised bounded Deep Source Review depth to support one additional hop, allowing flows such as official news archive -> press-release section -> year/detail page while preserving page, redirect, timeout, type, and SSRF limits.
+    *   (Ref: Web Search citations, Deep Source Review, `route_backend_chats.py`, `functions_source_review.py`, `admin_settings.html`, `test_web_search_current_message_only.py`, `test_source_review_deep_traversal.py`)
+
+*   **Deep Source Review Link Prioritization and Audit Detail**
+    *   Fixed Deep Source Review link extraction so relevant press-release/archive links are scored before link inventory limits are applied, preventing noisy navigation links from crowding out useful source-detail candidates.
+    *   Generic archive traversal now rejects shallow same-domain navigation such as About and Careers pages unless the link has a stronger source/archive signal.
+    *   Source Review audit logs and thought details now expose seed pages, child pages, Deep Source Review usage, planner attempted/used state, planner candidate count, and selected planner URLs.
+    *   (Ref: Deep Source Review, Source Review audit logging, `functions_source_review.py`, `route_backend_chats.py`, `test_source_review_deep_traversal.py`)
+
+*   **Deep Source Review Traversal Balance**
+    *   Improved Deep Source Review so seed/archive pages are reviewed before child links consume the remaining page budget, giving multi-source research requests better coverage across official sources.
+    *   Child-link scoring now favors generic release/detail archive patterns and downranks common navigation pages without adding company-specific heuristics.
+    *   (Ref: Deep Source Review, `functions_source_review.py`, `test_source_review_deep_traversal.py`, `SOURCE_REVIEW_DEEP_TRAVERSAL_FIX.md`)
+
+*   **Authenticated Request Login Activity Tracking**
+    *   Fixed login analytics so passive authenticated browser visits now contribute to login activity even when the user does not explicitly trigger the OAuth callback during that session.
+    *   Added throttled authenticated-request tracking to avoid inflating counts on every page load, while still preserving the explicit `azure_ad` login signal and avoiding an immediate duplicate on the post-login redirect.
+    *   This improves Control Center and profile login visibility for seamless SSO and session-reuse scenarios without changing the user-facing login flow.
+    *   (Ref: authenticated request login activity, `functions_activity_logging.py`, `app.py`, `route_frontend_authentication.py`, `test_authenticated_request_login_activity.py`, `AUTHENTICATED_REQUEST_LOGIN_ACTIVITY_FIX.md`)
+
+*   **Safety Violation Remediation Workflow**
+    *   Fixed the Safety Violations admin flow so `Warn user` now sends a user notification, `Suspend user` applies the same timed access restriction used by Control Center, and `Block user` applies the same indefinite deny path.
+    *   Safety admins who do not hold the required approval role now create a pending approval request instead of applying the remediation immediately, while eligible reviewers can still self-approve and execute their own request when policy allows it.
+    *   The safety review modal and shared approvals page now expose the notification details, suspension restore date, and explicit warn/suspend/block approval labels needed to review and execute those requests cleanly.
+    *   (Ref: `route_backend_safety.py`, `route_backend_control_center.py`, `functions_approvals.py`, `functions_safety_remediation.py`, `functions_notifications.py`, `admin_safety_violations.html`, `admin-safety-violations.js`, `approvals.html`, `test_safety_violation_remediation_approvals.py`)
+
+*   **Group and Public Workspace Hero Color Editing**
+    *   Fixed the group and public workspace manage pages so hero color selections now apply to the saved workspace branding instead of leaving those selectors effectively non-functional.
+    *   The manage-page hero preview now stays in sync with the selected color, and the saved branding metadata flows back through the workspace APIs for consistent rendering.
+    *   (Ref: workspace branding, `manage_group.js`, `manage_public_workspace.js`, `route_backend_groups.py`, `route_backend_public_workspaces.py`)
+
+*   **Chat-Scoped Generated Tabular Exports**
+    *   Fixed large tabular JSON and CSV export requests so the generated file now stays attached to the active chat instead of being pushed through the personal workspace document pipeline.
+    *   Assistant replies now keep the exhaustive dataset in a downloadable chat artifact with the existing preview card, which makes large structured outputs more reliable while keeping the visible answer concise.
+    *   Personal conversation deletion and retention cleanup now remove blob-backed generated chat files when archiving is disabled, closing the lifecycle gap for conversation-scoped exports.
+    *   (Ref: generated tabular exports, `route_backend_chats.py`, `functions_simplechat_operations.py`, `route_enhanced_citations.py`, `route_backend_conversations.py`, `functions_retention_policy.py`, `chat-messages.js`)
+
+*   **Fact Memory Delete Confirmation Layering**
+    *   Fixed the profile fact-memory workflow so the delete confirmation now opens above the Manage Fact Memories editor instead of appearing underneath it.
+    *   Users can now confirm or cancel a delete without closing the editor first, and the manager modal remains active so they can continue reviewing saved memories immediately after the confirmation closes.
+    *   Added focused UI regression coverage for the stacked modal behavior.
+    *   (Ref: fact memory management, `profile.html`, `test_profile_fact_memory_editor.py`)
+
+*   **Live Tabular Analysis Thought Progress**
+    *   Fixed long-running tabular analysis chats so workbook tool activity now streams into the thoughts panel while the answer is still being prepared, instead of waiting until the tabular pass completes.
+    *   Tabular requests now show a dedicated progress card with the current step, running and completed tool-call counts, and a clearer completion state when workbook evidence is ready.
+    *   Added focused UI regression coverage for the live tabular progress card and kept the adjacent agent-progress behavior covered.
+    *   (Ref: tabular analysis streaming, `route_backend_chats.py`, `chat-thoughts.js`, `test_chat_tabular_thought_progress.py`, `test_chat_agent_thought_progress.py`)
+

 *   **Global Agent Scope Gate Fallback**
     *   Fixed per-user Semantic Kernel chats so selecting a global agent no longer silently falls back to the standard GPT model when personal agents are disabled for the tenant.
     *   The per-user loader now treats global, personal, and group agent scopes separately, allowing valid global-agent selections to continue through agent invocation while keeping personal and group scope toggles enforced as configured.

 #### Bug Fixes
 
+*   **Requests Runtime Dependency Upgrade**
+    *   Updated the runtime HTTP client dependency from `requests==2.33.0` to `requests==2.33.1` in the main application requirements to keep deployment environments aligned with the latest pinned patch release.

 *   **Speech and Video Indexer Setup Guidance Alignment**
     *   Fixed stale admin guidance around Azure AI Video Indexer and shared Azure Speech configuration so managed-identity setup no longer points admins toward legacy Video Indexer API keys or incomplete Speech instructions.
     *   The admin experience now reflects the shared Speech resource model, adds Speech Resource ID helper fields, and keeps managed-identity voice-response requirements aligned with runtime behavior.

+
+## Open the right settings area
+
+1. Sign in with an account that has the **Admin** role.
+2. Open **Admin Settings**.
+3. Select **General**.
+4. Make changes in the relevant card and use **Save Settings**.
+5. Open the affected user page in a new browser tab or private window to verify the saved configuration.
+
+Most items in this guide live in **General** because they affect the shell of the application rather than a single workspace, model, or feature pack.
+
+## Branding
+
+Use **General > Branding** when you want the app header and landing experience to match the organization.
+
+| Setting | What it controls | Notes |
+| :--- | :--- | :--- |
+| **Application Title** | Browser title and visible app naming | Keep it short enough for navigation and browser tabs. |
+| **Show Logo** | Whether the app displays the configured logo in the interface | Enable this after uploading a logo. |
+| **Hide Application Title** | Whether the header shows text next to the logo | Use this only when the logo itself includes the product or organization name. |
+| **Main Page Logo Size** | Logo scale on the home page only | This does not change the top navigation or sidebar logo size. |
+| **Upload Custom Logo (Light Mode)** | Logo used in light mode | PNG or JPG/JPEG is accepted. The app stores the image at up to 500 pixels tall. |
+| **Upload Custom Logo (Dark Mode)** | Logo used in dark mode | If you skip this, the light-mode logo is reused. |
+| **Upload Custom Favicon** | Browser tab icon | PNG, JPG/JPEG, or ICO is accepted. 16x16 or 32x32 pixels works best. |
+
+After saving, check both light and dark themes. Logos that look crisp on a white background can disappear on dark mode if they use transparent dark text.
+
+## Home Page Text
+
+Use **General > Home Page Text** to control the copy users see before entering the app.
+
+1. Choose **Markdown Alignment**: left, center, or right.
+2. Enable **Markdown Editor** when you want to edit the landing page content in the admin page.
+3. Edit the **landing page text** using Markdown.
+4. Use the preview to check links, headings, and line breaks.
+5. Save and open the home page to confirm the final rendering.
+
+Good home page text usually answers three questions: who the app is for, what data handling expectations apply, and where users can get help. If you link to policy pages or internal guidance, use full URLs or application-relative paths that work in the deployed environment.
+
+## Health Checks
+
+Use **General > Health Check** when an uptime monitor, load balancer, or platform probe needs a lightweight endpoint.
+
+| Endpoint | Toggle | Response shape | When to use |
+| :--- | :--- | :--- | :--- |
+| `/external/healthcheck` | **Enable /external/healthcheck** | Plain timestamp text | Internal monitoring tools that can reach a protected application route. |
+| `/external/healthcheckz` | **Enable /external/healthcheckz** | JSON object with `status: "ok"` and `time` | Health probes that cannot sign in and only need availability. |
+
+Keep the unauthenticated endpoint behind trusted network paths when possible. It is intentionally small, but it still tells a caller that the app is reachable.
+
+## API Documentation
+
+Use **General > API Documentation** to control the live Swagger/OpenAPI route browser.
+
+1. Enable **Swagger/OpenAPI Documentation (/swagger)**.
+2. Save settings.
+3. Open `/swagger` in the deployed environment.
+4. Use `/swagger.json` or `/swagger.yaml` when a tool needs the OpenAPI document.
+
+Disable Swagger in environments where live route inspection should not be exposed to normal users. The repository-side OpenAPI artifact can still be used during review when a live environment is not available.
+
+## Classification Banner
+
+Use **General > Classification Banner** when every page should carry a visible sensitivity label.
+
+1. Enable **Classification Banner**.
+2. Enter the **Banner Text**, such as `Internal Use Only` or the label your organization requires.
+3. Pick the **Banner Color** and **Banner Text Color**.
+4. Check the preview for contrast before saving.
+5. Save and verify the banner on the home page, chat page, workspace pages, and admin pages.
+
+The banner is a visual reminder. It does not replace RBAC, workspace permissions, content safety, or data loss prevention controls.
+
+## Support Menu
+
+Use **General > Support** when users should have a predictable place for help, feedback, and release guidance.
+
+| Setting | What it does |
+| :--- | :--- |
+| **Enable Support Menu for End Users** | Adds the Support menu to user navigation. |
+| **Menu Name** | Renames the menu if your organization uses a different support label. |
+| **Enable Send Feedback Destination** | Lets users prepare a feedback email from the app. |
+| **Support Recipient Email** | Sets the internal recipient for user feedback drafts. |
+| **Enable Latest Features Destination** | Shows user-facing Latest Features under Support. |
+| **Show Simple Chat Documentation Guide Links** | Adds public documentation buttons to Latest Features cards. |
+| **User-Facing Latest Features** | Lets admins choose which feature announcements are visible to end users. |
+
+If **Send Feedback** is enabled, provide a real recipient address before saving. If the recipient is blank or invalid, the app disables the feedback destination and warns the admin.
+
+## External Links
+
+Use **General > External Links** when you want the app navigation to point to policy pages, prompt guides, help desks, training, or other internal resources.
+
+1. Enable **External Links in Navigation**.
+2. Set the **Menu Name**.
+3. Decide whether to enable **Force Menu Display**.
+4. Add each link with a label and URL.
+5. Save and verify the links in the main navigation.
+
+When **Force Menu Display** is off, one or two links can appear as top-level navigation items and three or more links become a dropdown. When it is on, links always appear under the external links menu.
+
+## System Settings
+
+Use **General > System Settings** for application-wide behavior that affects many workflows.
+
+| Setting | What it affects | Default |
+| :--- | :--- | :--- |
+| **Maximum File Size (MB)** | Upload validation for document and chat file workflows | 150 MB |
+| **Conversation History Limit** | Recent conversation turns sent into chat context | 10 |
+| **Default System Prompt** | Baseline instruction inserted when a conversation does not already have a general system prompt | Blank |
+
+Increasing file size or history limits can improve user flexibility, but it can also increase processing time, token use, and service cost. Change these deliberately and validate with a representative upload or chat workflow.
+
+## Validation checklist
+
+- Search the docs home page for the terms users are likely to type, such as `branding`, `home page text`, `health check`, `Swagger`, `classification banner`, `support menu`, and `external links`.
+- Open the home page after branding and landing page changes.
+- Check light and dark mode after logo changes.
+- Call the enabled health endpoint from the monitoring network path, not only from your workstation.
+- Open `/swagger` only in environments where API documentation should be visible.
+- Sign in as a normal user to verify Support and external link navigation.
+- Keep internal links, support email addresses, and classification labels aligned with your organization's policy language.

+# Create Custom Pages
+
+The canonical Custom Pages developer guide is maintained inside the application at:
+
+[application/single_app/docs/how-to/custom_pages.md](../../application/single_app/docs/how-to/custom_pages.md)
+
+Admin Settings > Custom Pages > Developer Guide renders that same Markdown in-app. Keeping the maintained copy inside `application/single_app` ensures the guide ships with non-container deployments, ACR-built containers, and any deployment process that sends only the app artifact.
+
+Use the linked source as the maintained guide for:
+
+- Simple HTML custom pages
+- Static HTML/CSS/JS custom pages
+- Python-backed Jinja custom pages with backend API operations
+
+Do not duplicate the full guide in this docs page. This page exists only to route developers to the same source the app renders.

+
+## Before You Start
+
+- Sign in to Simple Chat as an admin when creating global model endpoints.
+- Make sure you can assign Azure roles on the target Azure OpenAI resource, Foundry project, or backing Foundry resource.
+- Decide whether the endpoint is global, personal, or group scoped. The identity and RBAC requirements are the same, but the endpoint is saved in a different scope.
+- If you use a service principal, create the Entra app registration first and keep the tenant ID, client ID, and client secret ready.
+- If you use a user-assigned managed identity, attach it to the App Service and copy the managed identity **Client ID** for the modal.
+- Plan separate model endpoints when provider families need different project settings, authentication, or manual deployment rows. For Foundry project model inference, Simple Chat normalizes calls to `/openai/v1`, so keep **OpenAI API Version** at endpoint default `v1`.
+
+## Choose The Provider
+
+The modal provider decides which discovery API and token scope Simple Chat uses.
+
+| Provider in the modal | Use it for | Endpoint value | RBAC target |
+|-----------------------|------------|----------------|-------------|
+| `Azure OpenAI` | Direct Azure OpenAI resource endpoints and Azure OpenAI-compatible APIM paths | `https://<openai-resource>.openai.azure.com/` for direct Azure OpenAI | The Azure OpenAI resource, or a parent resource group/subscription when your access model requires it |
+| `Foundry (classic)` | Existing classic Foundry project agents and model deployments | `https://<foundry-resource>.services.ai.azure.com/api/projects/<project>` or the project base endpoint plus **Foundry Project Name** | The Foundry project when the portal exposes project-scoped access, otherwise the backing Foundry resource/account |
+| `New Foundry` | Application-based Foundry runtime, New Foundry agents, and OpenAI-compatible project model deployments | The same Foundry project endpoint shape used by the New Foundry project | The Foundry project when the portal exposes project-scoped access, otherwise the backing Foundry resource/account |
+
+For APIM, choose the provider that matches the backend service and select API key authentication when APIM expects a subscription key or other shared key. API key authentication can run inference, but it cannot use **Fetch Models** for Azure OpenAI ARM discovery or Foundry project discovery.
+
+## Choose API Versions
+
+The modal has two version fields, and they are intentionally separate.
+
+| Field | What it controls | Recommended starting point |
+|-------|------------------|----------------------------|
+| **Project API Version** | Foundry project discovery calls such as deployment listing, agent listing, and workflow listing. | Keep `v1` unless your Foundry project documentation says otherwise. |
+| **OpenAI API Version** | Inference calls for OpenAI-compatible Foundry project model deployments. Simple Chat normalizes Foundry project endpoints to `/openai/v1`. | Keep `Endpoint default (v1)` for New Foundry project model endpoints. The `/v1` path does not allow an `api-version` query, including dated preview values. |
+
+If one deployed model family works and another fails with API-version or unsupported-operation errors, create a separate endpoint for the failing family so you can isolate its project endpoint, authentication, deployment rows, and test results. For the normalized `/openai/v1` inference path, keep **OpenAI API Version** at endpoint default `v1`.
+
+Claude deployments are detected from the deployment name or Anthropic endpoint path and use the Anthropic messages protocol at runtime. The endpoint still stores an OpenAI API Version for the other model rows on that endpoint, so keep Claude with compatible rows or use a separate endpoint when the configuration becomes confusing.
+
+Live validation against Foundry-hosted model families showed that basic chat-completions calls work for DeepSeek, Grok, and Llama, but reasoning-effort support and memory context tolerance are model-specific. Simple Chat only sends reasoning effort to known OpenAI reasoning families such as GPT-5 and o-series models. For Foundry-hosted non-OpenAI chat-completions models, Simple Chat folds saved memory values into the latest user message as plain background notes instead of injecting memory system messages. This preserves memory context while avoiding provider-side content-filter blocks observed with system-style memory prompts.
+
+The same endpoint runtime helpers are used for chat streaming, workflow execution, metadata extraction, endpoint test calls, and Semantic Kernel-backed tabular or agent services. This keeps provider selection, authentication, OpenAI-compatible `/openai/v1` normalization, and Anthropic routing consistent across Simple Chat features.
+
+## Understand Discovery Versus Inference
+
+The modal has two separate behaviors that often require different permissions.
+
+| Modal action | Azure OpenAI provider | Foundry providers |
+|--------------|-----------------------|-------------------|
+| **Fetch Models** | Uses Azure Resource Manager through the Cognitive Services management API to list deployments. It needs management-plane read access plus data-plane access for later inference. | Uses the Foundry project deployments API. It needs Entra ID access to the Foundry project. API keys are not supported for this discovery path. |
+| **Test Model** | Calls the selected deployment for chat inference. Managed identity and service principal use Azure OpenAI Entra auth; API key uses the configured key. | Calls the selected project deployment. Managed identity and service principal use the Foundry token scope. API key is inference-only where the target endpoint accepts it. |
+| Agent or workflow import | Not used for local Azure OpenAI models. | Classic Foundry, New Foundry, and Foundry Workflow discovery require Entra ID/RBAC. API keys are not used for chat-selectable Foundry agents or workflows. |
+
+## Assign Roles
+
+Grant roles to the exact principal that Simple Chat will use from the modal.
+
+| Scenario | Principal to assign | Scope | Minimum roles |
+|----------|---------------------|-------|---------------|
+| Azure OpenAI with managed identity or service principal, including **Fetch Models** | App Service system-assigned identity, user-assigned identity, or service principal enterprise application | Azure OpenAI resource. Use resource group or subscription scope only when your organization manages access there. | `Reader` for deployment discovery, plus `Cognitive Services OpenAI User` for inference |
+| Azure OpenAI inference with manually entered model rows | Same identity or service principal | Azure OpenAI resource | `Cognitive Services OpenAI User` |
+| Foundry (classic) project model discovery or classic agent import | Same identity or service principal | Foundry project when available, otherwise the backing Foundry resource/account | `Foundry User` in commercial clouds, or `Azure AI User` where that older name is still shown |
+| New Foundry project model discovery, application discovery, or Responses runtime | Same identity or service principal | Foundry project when available, otherwise the backing Foundry resource/account | `Foundry User` in commercial clouds, or `Azure AI User` where that older name is still shown |
+| Foundry project administration outside Simple Chat, such as creating projects, apps, deployments, or assigning dependent roles | Admin operator or automation service principal | Foundry project, resource, account, or subscription according to your governance model | `Foundry Project Manager`, `Foundry Owner`, or `Foundry Account Owner` as appropriate. Azure Government and custom clouds may still show `Azure AI Project Manager`, `Azure AI Owner`, or `Azure AI Account Owner`. |
+
+Keep runtime identities narrow. A managed identity or service principal used by Simple Chat usually needs user-level access to invoke and discover resources, not owner-level access to administer the Foundry account.
+
+## Assign Access In Azure Portal
+
+Use these steps for each target resource and role.
+
+1. Open the target Azure OpenAI resource, Foundry project, or backing Foundry resource in Azure portal or Foundry portal.
+2. Open **Access control (IAM)** for Azure resources, or the project access page for project-scoped Foundry roles.
+3. Select **Add role assignment**.
+4. Choose the required role from the table above.
+5. For a system-assigned managed identity, choose **Managed identity**, select **App Service**, then select the Simple Chat App Service.
+6. For a user-assigned managed identity, choose **Managed identity**, select **User-assigned managed identity**, then select the identity attached to the App Service.
+7. For a service principal, choose **User, group, or service principal**, then search for the enterprise application by display name or client ID.
+8. Review and assign. Repeat for every role and resource scope required by the provider.
+
+## Assign Access With Azure CLI
+
+Use the object ID of the managed identity or enterprise application when possible.
+
+```bash
+# Azure OpenAI direct resource: discovery plus inference
+az role assignment create \
+  --assignee-object-id <principal-object-id> \
+  --assignee-principal-type ServicePrincipal \
+  --role "Reader" \
+  --scope <azure-openai-resource-id>
+
+az role assignment create \
+  --assignee-object-id <principal-object-id> \
+  --assignee-principal-type ServicePrincipal \
+  --role "Cognitive Services OpenAI User" \
+  --scope <azure-openai-resource-id>
+
+# Foundry project or backing Foundry resource: discovery and invocation
+az role assignment create \
+  --assignee-object-id <principal-object-id> \
+  --assignee-principal-type ServicePrincipal \
+  --role "Foundry User" \
+  --scope <foundry-project-or-resource-scope>
+```
+
+If the target cloud still lists the earlier role names, replace `Foundry User` with `Azure AI User`. For custom clouds, use the role name and role assignment scope exposed by that cloud.
+
+## Configure Azure OpenAI
+
+1. Open **Admin Settings** and go to **AI Models** for global endpoints, or open the personal/group workspace endpoint management area for scoped endpoints.
+2. Add or edit a **Model Endpoint**.
+3. Set **Provider** to **Azure OpenAI**.
+4. Enter an endpoint name and the Azure OpenAI resource endpoint, such as `https://<openai-resource>.openai.azure.com/`.
+5. Select the **OpenAI API Version** used by the deployment.
+6. For managed identity, set **Authentication Type** to **Managed Identity**. Choose **System Assigned** or **User Assigned**. For user-assigned identity, enter the identity client ID.
+7. For service principal, set **Authentication Type** to **Service Principal** and enter tenant ID, client ID, and client secret.
+8. Enter **Subscription ID** and **Resource Group** when using managed identity or service principal. These are required for **Fetch Models** because Azure OpenAI discovery uses ARM deployment listing.
+9. Select **Fetch Models**. Confirm the expected deployments appear, then use **Test Model** on at least one model row.
+10. Save the endpoint, then save settings when you are in Admin Settings.
+
+For API key mode, enter the endpoint, OpenAI API version, and API key. Add model rows manually if **Fetch Models** is unavailable, because API key authentication is inference-only for this modal.
+
+## Configure Foundry Classic
+
+Use **Foundry (classic)** when the target is an existing classic Foundry project or classic Foundry agent flow.
+
+1. Grant the identity or service principal `Foundry User` or `Azure AI User` on the target Foundry project or backing Foundry resource.
+2. Add or edit a **Model Endpoint**.
+3. Set **Provider** to **Foundry (classic)**.
+4. Enter the Foundry project endpoint. If the endpoint already contains `/api/projects/<project>`, the modal can infer the project name. Otherwise, fill **Foundry Project Name**.
+5. Keep **Project API Version** at `v1` unless your Foundry project specifically requires another supported value.
+6. Keep **OpenAI API Version** at **Endpoint default (v1)** for Foundry project model inference. Simple Chat normalizes these calls to `/openai/v1`, and that path rejects `api-version` query values.
+7. Select **Managed Identity** or **Service Principal** and fill the identity fields.
+8. For Azure Government, set **Management Cloud** to **Azure Government**. For a custom cloud, set **Management Cloud** to **Custom**, then enter the custom authority and Foundry scope.
+9. Select **Fetch Models** to verify project deployment discovery.
+10. When importing classic Foundry agents, use the saved endpoint from the agent modal and fetch the classic agents from that project.
+
+## Configure New Foundry
+
+Use **New Foundry** for the application-based Foundry runtime and New Foundry agent/application flows.
+
+1. Grant the identity or service principal `Foundry User` or `Azure AI User` on the target Foundry project or backing Foundry resource.
+2. Add or edit a **Model Endpoint**.
+3. Set **Provider** to **New Foundry**.
+4. Enter the New Foundry project endpoint. If the URL does not include `/api/projects/<project>`, fill **Foundry Project Name**.
+5. Keep **Project API Version** at `v1` unless your Foundry project requires a different supported value.
+6. Keep **OpenAI API Version** at **Endpoint default (v1)** for New Foundry project model inference. Simple Chat normalizes these calls to `/openai/v1`, and that path rejects `api-version` query values. Claude deployments are detected from the model name and use the Anthropic messages protocol.
+7. Select **Managed Identity** or **Service Principal** and fill the identity fields.
+8. Set **Management Cloud** for public, Azure Government, or custom cloud. Custom cloud requires both **Custom Authority** and **Foundry Scope**.
+9. Select **Fetch Models** and test a deployment.
+10. When creating New Foundry agents, use the saved endpoint in the agent modal so application discovery and runtime calls use the same identity and project settings.
+
+API keys are not a replacement for Foundry RBAC when users need New Foundry agent discovery, Foundry Workflow discovery, or chat-selectable Foundry agent invocation. For API-key-only model inference, **Fetch Models** is unavailable; add each deployment row manually and test it before saving.
+
+## Validate The Setup
+
+- **Fetch Models** returns the expected model deployments for the selected provider.
+- **Test Model** succeeds for at least one enabled model row.
+- Classic Foundry agent fetch, New Foundry application fetch, or Foundry Workflow fetch succeeds when you configure those agent types.
+- A normal user can select the model or agent in chat only when the endpoint scope and governance settings allow it.
+- Application logs do not show `403`, `401`, missing client secret, missing project name, or missing subscription/resource group errors.
+
+## Troubleshooting
+
+| Symptom | Likely cause | Fix |
+|---------|--------------|-----|
+| Azure OpenAI **Fetch Models** fails | The identity can call inference but cannot read ARM deployment metadata. | Add `Reader` on the Azure OpenAI resource or correct parent scope, and confirm subscription ID, resource group, and endpoint resource name match. |
+| Azure OpenAI **Test Model** fails with authorization errors | Missing data-plane role. | Add `Cognitive Services OpenAI User` on the Azure OpenAI resource. |
+| Foundry **Fetch Models** fails | Wrong provider, wrong project endpoint, missing project name, wrong cloud authority/scope, or missing Foundry RBAC. | Confirm provider is Foundry (classic) or New Foundry, verify the project endpoint, then assign `Foundry User` or `Azure AI User` to the modal identity. |
+| Grok, Meta/Llama, DeepSeek, or another non-OpenAI provider fails with `api-version query parameter is not allowed when using /v1 path` | A dated preview or other query-style **OpenAI API Version** is being applied to the normalized `/openai/v1` inference path. | Keep **OpenAI API Version** at `Endpoint default (v1)`, save the endpoint, then run **Test Model** again. |
+| DeepSeek, Grok, Llama, or another non-OpenAI family returns empty content or content-filter errors only from Simple Chat | The request may include model-family-specific parameters such as `reasoning_effort`. | Use the current Simple Chat version, which sends reasoning effort only to known OpenAI reasoning families, then test the model again. |
+| DeepSeek, Grok, Llama, or another non-OpenAI family works in direct probes but fails only in the app | App-added memory system messages may trigger provider-side content filters. | Use the current Simple Chat version, which folds saved memory values into the latest user message as plain background notes for non-OpenAI Foundry models. |
+| Service principal cannot authenticate | Tenant ID, client ID, or secret is incorrect, expired, or saved against the wrong endpoint. | Rotate the secret, update the endpoint, and confirm the enterprise application has the role assignment. |
+| User-assigned managed identity is ignored | The client ID is missing or the identity is not attached to the App Service. | Attach the identity to the App Service and enter the managed identity client ID, not the object ID. |
+| API key endpoint cannot fetch models | API key mode is inference-only for discovery paths. | Add model rows manually, or switch to managed identity/service principal and assign RBAC. |

+# Microsoft Teams App Configuration
+
+This guide explains how to run SimpleChat as a Microsoft Teams personal tab with Teams Single Sign-On (SSO).
+
+## Enablement Model
+
+Teams SSO requires two layers:
+
+1. A Teams app package installed in Teams. The package contains the Teams manifest, icons, tab URL, valid domain, and `webApplicationInfo` values.
+2. SimpleChat runtime configuration. The app must enable `ENABLE_TEAMS_SSO`, allow Teams framing in Content Security Policy, use cross-site secure session cookies, and allow the Teams login page to reach the Flask authentication flow.
+
+The Bicep deployer exposes `enableTeamsSso` for the runtime layer. It does not install the Teams app package into Teams; a Teams administrator or developer still uploads the generated app package.
+
+## Prerequisites
+
+- An Entra app registration for SimpleChat.
+- The SimpleChat application URL, such as `https://simplechat.contoso.com`.
+- Permission to update the Entra app registration.
+- Permission to upload or publish a custom Teams app.
+
+## Entra App Registration
+
+### Expose An API
+
+1. Open the SimpleChat app registration in the Azure portal.
+2. Select **Expose an API**.
+3. Set the Application ID URI to a stable URI for the SimpleChat web app.
+
+Example:
+
+```text
+api://simplechat.contoso.com/00000000-0000-0000-0000-000000000000
+```
+
+4. Add a delegated scope named `access_as_user`.
+5. Allow admins and users to consent, or use your tenant policy standard.
+
+### Preauthorize Teams Clients
+
+Under **Authorized client applications**, add the Teams clients that should acquire the `access_as_user` token.
+
+Common Teams client IDs:
+
+```text
+5e3ce6c0-2b1f-4285-8d4b-75ee78787346
+1fec8e78-bce4-4aaf-ab1b-5451cc387264
+4345a7b9-9a63-4910-a426-35363201d503
+```
+
+Select the `access_as_user` scope for each client.
+
+## SimpleChat Runtime Configuration
+
+### Bicep Deployment
+
+Set `enableTeamsSso` to `true` when deploying SimpleChat.
+
+```json
+{
+  "enableTeamsSso": {
+    "value": true
+  },
+  "teamsAppResource": {
+    "value": "api://simplechat.contoso.com/00000000-0000-0000-0000-000000000000"
+  }
+}
+```
+
+When `enableTeamsSso` is true, the deployer sets these app settings for you:
+
+- `ENABLE_TEAMS_SSO=true`
+- `SESSION_COOKIE_SAMESITE=None`
+- `SESSION_COOKIE_SECURE=true`
+- `TEAMS_SUCCESS_REDIRECT_PATH=/chats`
+- `TEAMS_APP_RESOURCE=<teamsAppResource value>` when supplied
+
+The deployer also changes App Service Authentication (`authsettingsV2`) so unauthenticated requests can reach SimpleChat's app-level login flow. Teams cannot complete tab SSO if Easy Auth redirects the iframe to the Microsoft login page before `/login?teams=true` loads.
+
+### Environment Variables
+
+For manual deployments, set:
+
+```bash
+ENABLE_TEAMS_SSO=true
+SESSION_COOKIE_SAMESITE=None
+SESSION_COOKIE_SECURE=true
+TEAMS_APP_RESOURCE=api://simplechat.contoso.com/00000000-0000-0000-0000-000000000000
+```
+
+Commercial Azure and Azure Government deployments get default Teams frame origins when `ENABLE_TEAMS_SSO=true`.
+
+Use these only when you need to override the defaults, such as custom or air-gapped Teams clouds:
+
+```bash
+TEAMS_FRAME_ANCESTORS=https://teams.example.cloud https://*.teams.example.cloud
+CUSTOM_TEAMS_ORIGINS=["https://teams.example.cloud", "https://*.teams.example.cloud"]
+```
+
+`TEAMS_FRAME_ANCESTORS` controls the server Content Security Policy `frame-ancestors` directive. `CUSTOM_TEAMS_ORIGINS` is passed to the Teams JavaScript SDK initialization call.
+
+## Teams App Manifest
+
+Use [application/teams_app/manifest.template.json](../../application/teams_app/manifest.template.json) as the starting point.
+
+Replace these placeholders:
+
+- `TEAMS_APP_ID`: A Teams app ID. This can be a generated GUID and does not have to be the Entra client ID.
+- `HOSTNAME`: The SimpleChat host name without `https://`, such as `simplechat.contoso.com`.
+- `CLIENT_ID`: The Entra app registration client ID.
+- `TEAMS_APP_RESOURCE_URI`: The Application ID URI from **Expose an API**, such as `api://simplechat.contoso.com/<client-id>`.
+
+The personal tab `contentUrl` should stay pointed at:
+
+```text
+https://HOSTNAME/login?teams=true
+```
+
+Package these files into a zip:
+
+```text
+manifest.json
+color.png
+outline.png
+```
+
+The generated `manifest.json` and zip file are intentionally ignored by Git.
+
+## Cloud Notes
+
+### Azure Commercial
+
+Default Teams frame ancestors:
+
+```text
+https://teams.microsoft.com https://*.teams.microsoft.com
+```
+
+### Azure Government
+
+Default Teams frame ancestors:
+
+```text
+https://teams.microsoft.us https://*.teams.microsoft.us
+```
+
+### Custom Clouds
+
+Set `teamsFrameAncestors`, `customTeamsOrigins`, and `teamsAppResource` explicitly. Also verify Graph authority and Graph endpoint settings for the target cloud, because Teams SSO exchanges the Teams assertion for Microsoft Graph delegated scopes.
+
+## Test Flow
+
+1. Deploy SimpleChat with Teams SSO enabled.
+2. Confirm `/login?teams=true` loads without an App Service Authentication redirect.
+3. Upload the Teams app package in Teams.
+4. Open the SimpleChat tab in Teams.
+5. Confirm the tab signs in and redirects to `/chats`.
+
+## Troubleshooting
+
+### Failed To Get Authentication Token
+
+- Confirm `webApplicationInfo.resource` exactly matches `TEAMS_APP_RESOURCE` and the Entra Application ID URI.
+- Confirm Teams client applications are preauthorized for `access_as_user`.
+- Confirm the Teams manifest `validDomains` includes the SimpleChat host name.
+
+### Teams Sign-In Falls Back To Microsoft Sign-In
+
+- Confirm `ENABLE_TEAMS_SSO=true`.
+- Confirm the Teams tab URL is `/login?teams=true`.
+- Confirm the local Teams SDK file is served from `/static/js/MicrosoftTeams.min.js`.
+
+### App Does Not Load In The Teams Frame
+
+- Confirm `TEAMS_FRAME_ANCESTORS` includes the Teams host for your cloud.
+- Confirm `X-Frame-Options` is not emitted when Teams SSO is enabled.
+- Confirm App Service Authentication allows unauthenticated requests to the app-level login flow.
+
+### Session Does Not Persist
+
+- Confirm HTTPS is used.
+- Confirm `SESSION_COOKIE_SAMESITE=None`.
+- Confirm `SESSION_COOKIE_SECURE=true`.
+
+## Local Teams SDK Asset
+
+SimpleChat vendors the Teams JavaScript SDK under `application/single_app/static/js/MicrosoftTeams.min.js` so disconnected and sovereign environments do not load browser runtime JavaScript from a public CDN.

 If your App Service is already configured to pull its image from Azure Container Registry and your goal is to avoid any infrastructure reprovisioning, you can use an image-only rollout.
 
+For the Azure CLI deployer specifically, the repo now includes `deployers/azurecli/upgrade-simplechat.ps1` for that path. It performs the code-only rollout in PowerShell by building the image in ACR and updating the existing App Service container configuration.
+
 The repo already contains an image publish workflow:

+description: "How assigned knowledge, reusable identities, Databricks actions, and MCP actions expand agent governance"
+section: "Latest Release"
+---
+
+Agent Knowledge and Actions combines governed agent retrieval with expanded enterprise action types and reusable identity workflows.
+
+## User Side
+
+Workspace users can review Agents and Actions from Personal Workspace, chat with configured agents, inspect enabled tools, and use reusable identities where actions need credentials.
+
+## Admin Side
+
+Admins and workspace owners govern which agents, actions, identities, and Microsoft Graph mail behaviors are available before assigning them to users. The visual tour includes Assigned Knowledge setup plus user-facing Agents and Actions views.
+
+## Microsoft Graph Mail Actions
+
+Microsoft Graph actions now include a **Send mail** capability. Action owners can configure whether the action creates a manual draft, prepares a delayed-delivery draft, or sends mail automatically from the signed-in user's mailbox.
+
+<img src="{{ '/images/feature-msgraph-mail-delivery.png' | relative_url }}" alt="Annotated Microsoft Graph action configuration showing Send mail and Mail Delivery controls." style="width: 70%;" />
+
+## Why It Matters
+
+Agent creators can make assistants more predictable while admins keep cleaner credential and action governance.
+
+## How to Try It
+
+1. Open an agent create or edit modal and review the **Knowledge** step.
+2. Assign workspaces, documents, tags, and optional web sources that should anchor the agent.
+3. Review workspace or global identities before configuring actions that need credentials.
+4. Use Databricks, MCP, or Microsoft Graph action types when approved external tools should be available to agents.
+5. For Microsoft Graph mail actions, enable **Send mail** and choose the default **Mail Delivery** behavior before assigning the action to an agent.
+
+## Notes
+
+- Assigned Knowledge is stored with the agent configuration and applied when the agent is selected.
+- User-added workspace context can be allowed or restricted based on agent policy.
+- Databricks, MCP, and Microsoft Graph actions should be reviewed with the same care as other tool integrations.

+section: "Latest Release"
+---
+
+Current release version: **0.241.183**
+
+Analyze and Compare give users deliberate document-action modes beyond regular workspace search.
+
+## User Side
+
+Users can open the Workspaces tool in Chat and choose **Analyze** when a prompt should review selected documents end to end. They can choose **Compare** when one source document should be compared against one or more target documents. Workspace document actions and workflow configuration reuse the same document-action concepts when a repeated review is needed.
+
+## Admin Side
+
+Admins enable the underlying workspace, enhanced citation, and workflow capabilities that determine where document actions appear. Analyze and Compare respect the user's current workspace access and document selection rather than exposing documents outside the active scope.
+
+## Screenshot Placeholder
+
+Add a user screenshot showing the Chat Workspaces tool with Search, Analyze, and Compare available as document action modes.
+
+Add a second screenshot showing a Compare setup with one source document and one or more target documents selected.
+
+## Why It Matters
+
+Some questions need exhaustive review or side-by-side comparison instead of top-search snippets.
+
+## How to Try It
+
+1. Open Chat and expand the Workspaces tool.
+2. Select a workspace scope and choose one or more documents.
+3. Choose **Analyze** for full-document review or **Compare** for source-versus-target comparison.
+4. Send a prompt and review the progress, coverage, citations, and final answer.
+
+## Notes
+
+- Interactive chat analysis targets a deliberately bounded set of selected documents.
+- Workflow Analyze runs can cover larger repeated batches and changed synced documents.
+- Compare treats one selected document as the source baseline and compares selected target documents against it.

+description: "How everyday chat flows became faster with paste uploads, document actions, paging, masking, charts, and prompt actions"
+section: "Latest Release"
+---
+
+Current release version: **0.241.183**
+
+Chat Productivity groups the everyday improvements that make repeated chat work faster and more comfortable, including Analyze and Compare document actions from the Workspaces tool.
+
+## User Side
+
+Users work from the chat composer: attach files or URLs, switch models, choose prompts and agents, ground messages in workspace sources, paste screenshots, choose Search, Analyze, or Compare for selected documents, and continue from generated charts or artifacts.
+
+## Admin Side
+
+Admins enable the underlying chat, upload, model endpoint, Source Review, and workspace capabilities that determine which composer tools are visible in a given deployment.
+
+## Screenshot Placeholder
+
+Add a user screenshot showing the Chat Workspaces tool with **Analyze** selected for one or more documents.
+
+Add a user screenshot showing the Compare setup, with one source document and one or more target documents visible before sending.
+
+## Why It Matters
+
+Frequent chat tasks should feel lighter, especially when users have many conversations, pasted images, long-running answers, or reusable generated outputs.
+
+## How to Try It
+
+1. Paste copied screenshots or browser-exposed files directly into the chat input when uploads are enabled.
+2. Use Analyze when selected documents need full review instead of search snippets.
+3. Use Compare when one source document should be checked against one or more target documents.
+4. Use conversation search and **Load More** behavior when browsing larger conversation histories.
+5. Try suggested prompt buttons, message masking, inline charts, and generated Markdown previews when those controls appear in a response.
+
+## Notes
+
+- Clipboard uploads depend on browser support and enabled upload settings.
+- Analyze and Compare depend on workspace document access and selected document scope.
+- Paged conversation loading keeps startup faster for users with many conversations.
+- Charts and artifact previews are designed to keep analysis results easier to inspect in place.

+description: "How chat uploads become personal or group workspace documents depending on conversation scope"
+section: "Latest Release"
+---
+
+Current release version: **0.241.183**
+
+Chat Upload Workspace Parity keeps chat uploads familiar while making the matching workspace document the durable source of truth whenever workspace processing is available.
+
+## User Side
+
+In personal conversations, an eligible chat upload becomes a personal workspace document, gets linked back to the conversation, and appears in chat as a workspace-backed file message. In group and group multi-user conversations, eligible uploads go to the writable group workspace instead of the user's personal workspace. After processing, the file can be searched, analyzed, compared, cited, tagged, and governed through normal workspace flows.
+
+## Admin Side
+
+Admins enable chat file uploads, personal workspaces, group workspaces, and the workspace upload pipeline that makes the handoff possible. Group upload destinations still respect group write roles, so users who can chat in a group do not automatically gain permission to add documents to that group workspace.
+
+## Screenshot Placeholder
+
+Add a personal chat screenshot showing an uploaded file message with workspace-backed processing progress and a linked personal workspace document.
+
+Add a group chat screenshot showing the group upload destination picker or a group workspace document created from a group conversation.
+
+## Why It Matters
+
+A file added in chat should become useful workspace knowledge without asking users to re-upload it somewhere else.
+
+## How to Try It
+
+1. Open a personal chat and upload a supported file.
+2. Wait for workspace processing to complete and confirm the file is linked from the conversation.
+3. Open the Workspaces tool or Personal Workspace and use Search, Analyze, or Compare against the uploaded document.
+4. Repeat from a group or group multi-user conversation and confirm the uploaded file lands in the group workspace when you have a writable group role.
+
+## Notes
+
+- Personal chat uploads hand off to personal workspace documents when personal workspaces are enabled.
+- Group and group multi-user chat uploads hand off to group workspace documents and require a writable group role.
+- When workspace handoff is not available, the existing chat-only upload behavior remains the fallback for eligible scenarios.

+
+Current release version: **0.241.183**
+
+Cloud and Anthropic Model Support lets admins configure Azure OpenAI, Foundry, New Foundry, and Claude-capable deployments in the same model endpoint system users already see in Chat.
+
+## User Side
+
+Users choose from the model picker when admins expose multiple options. A Claude-backed endpoint appears as another approved model choice, so users can select it for the next turn without changing how they use prompts, agents, workspace grounding, or chat history.
+
+## Admin Side
+
+Admins configure model endpoints from **Admin Settings > AI Models**. Provider metadata distinguishes Azure OpenAI, Foundry, and New Foundry endpoints, and cloud-aware fields support Azure Public, Azure Government, and custom authority scenarios. Claude deployments are detected from the configured model name or Anthropic endpoint path and route through the Anthropic messages protocol at runtime.
+
+## Screenshot Placeholder
+
+Add an admin screenshot showing the model endpoint modal with provider, project endpoint, cloud, and model choices filled in for a Claude deployment.
+
+Add a user screenshot showing the Chat model picker with an Azure OpenAI model and a Claude-capable Foundry model visible in the same menu.
+
+## Why It Matters
+
+Teams can adopt Anthropic models through approved Azure AI Foundry endpoints without building a separate chat experience or losing existing model-governance controls.
+
+## How to Try It
+
+1. Open **Admin Settings > AI Models** and enable multi-model endpoints.
+2. Add or edit a Foundry or New Foundry endpoint that exposes a Claude deployment.
+3. Save the endpoint and make the model available to the intended users or scopes.
+4. Open Chat and select the model from the model picker before sending a prompt.
+
+## Notes
+
+- Claude deployments use the Anthropic messages protocol instead of the legacy Azure OpenAI client path.
+- OpenAI-compatible Foundry models continue through the Foundry OpenAI-compatible path.
+- Summary generation, endpoint-bound agents, and direct chat calls preserve endpoint metadata so Claude selections stay on the right protocol.

+---
+
+Cosmos Throughput Autoscale brings Cosmos DB request-unit monitoring, guarded scaling controls, policy enforcement, and native autoscale conversion into the Admin Settings Scale experience.
+
+## User Side
+
+This is intentionally an administrator and operator feature. End users benefit from steadier app capacity, but they do not receive Cosmos data-plane access or direct autoscale controls.
+
+## Admin Side
+
+Admins enable and operate this from **Admin Settings > Scale**. The screenshot gallery focuses on access validation, global scale policies, container guardrails, and native autoscale conversion controls that operators need before turning on automation.
+
+## Why It Matters
+
+Administrators can respond to capacity pressure without exposing Cosmos data-plane permissions to agents, actions, or end users.
+
+## How to Try It
+
+1. Open **Admin Settings > Scale** and refresh the Cosmos DB Throughput card.
+2. Use **Validate Access** before enabling automation in a new or changed deployment.
+3. Review global policy settings and container policies for dedicated-throughput containers.
+4. Use native autoscale conversion only for eligible manual throughput resources.
+
+## Notes
+
+- This is primarily an administrator and operator capability.
+- Background automation follows configured guardrails, cooldowns, and metrics windows.
+- The least-privilege operator role is separate from Cosmos DB data-plane access.

+section: "Latest Release"
+---
+
+Document Intelligence Auto Mode lets admins choose how PDF and image uploads are extracted while giving workspace users clearer visibility into the extraction path used for each document.
+
+## User Side
+
+Workspace users can expand document rows to review Standard, Enhanced, Auto, and enhanced-citation badges, then use metadata or Change Extraction actions when a stored PDF needs a different processing path.
+
+## Admin Side
+
+Admins configure extraction behavior from **Admin Settings > Search & Extract**. The screenshot gallery shows the admin extraction-mode controls alongside the user document-details view so teams can connect the setting to the visible workspace experience.
+
+## Why It Matters
+
+Teams can keep fast extraction for simple files while still capturing tables, forms, and selection marks when a document needs richer layout understanding.
+
+## How to Try It
+
+1. Open **Admin Settings > Search & Extract** and review the Document Intelligence extraction mode.
+2. Choose **Read** for fast OCR-style extraction, **Layout** for richer structure, or **Auto** when SimpleChat should sample the PDF before deciding.
+3. Open a workspace document list and review extraction badges or PDF reprocess actions when source blobs are available.
+
+## Notes
+
+- Auto mode samples PDF pages and uses richer extraction when document structure suggests it is useful.
+- Reprocessing depends on the original source blob still being available.
+- Image and PDF extraction settings are managed by admins.

+
+Current release version: **0.241.183**
+
+File Sync now supports richer workspace ingestion from SMB shares and Azure Files while keeping the existing document processing, chunking, embedding, and search pipeline.
+
+## User Side
+
+Workspace users and managers can add SMB or Azure Files sync sources, browse supported folders where available, select files or folders, run sync, review history, and reuse workspace identities when credentials are needed.
+
+## Admin Side
+
+Admins choose whether SMB Share and Azure Files connector types are available and configure reusable identity options from Admin Settings. The screenshot gallery pairs those admin controls with the user Sync and Identities tabs.
+
+## Screenshot Placeholder
+
+Add a current admin screenshot showing only SMB Share and Azure Files as enabled source-type controls.
+
+Add a user screenshot showing a workspace Sync tab with one SMB source and one Azure Files source so the active connector set is obvious.
+
+## Why It Matters
+
+Workspace documents can stay closer to authoritative external stores instead of depending on manual re-upload habits.
+
+## How to Try It
+
+1. Open a workspace with File Sync enabled and go to the **Sync** tab.
+2. Add a source using one of the enabled source types: SMB or Azure Files.
+3. Browse supported provider folders, choose selected files or folders, and review sync history after a run.
+4. Use reusable identities where available so credentials are managed separately from the source definition.
+
+## Notes
+
+- Admins control which File Sync source types are visible.
+- SMB and Azure Files flows can use provider-specific connection and identity setup.
+- Other cloud-drive connectors are not part of the current user-facing File Sync connector set while validation continues.
+- Synced documents continue through the normal SimpleChat indexing and search pipeline.

+Generated Artifacts make large Markdown, tabular, and analysis outputs easier to inspect, download, and promote into durable workspace knowledge.
+
+## User Side
+
+Users can review generated Markdown, charts, and structured outputs in Chat, open artifact controls, download reusable outputs, and promote artifacts into workspaces when the content should become durable knowledge.
+
+## Admin Side
+
+Admins govern the workspace features, enhanced citation pipeline, and group or public approval flows that determine where generated artifacts can be promoted and when shared artifacts become searchable.
+
+## Why It Matters
+
+Large or reusable generated outputs can move from conversation context into durable workspace documents without making chat answers unwieldy.
+
+## How to Try It
+
+1. Generate a Markdown or analysis output from Chat or a workflow.
+2. Use **View MD** when you want to inspect rendered Markdown before downloading it.
+3. Use artifact cards for large generated outputs that should stay attached to the chat.
+4. Choose **Add to Workspace** when an artifact should become a personal, group, or public workspace document.
+
+## Notes
+
+- Group and public workspace promotions can require approval before artifacts become searchable.
+- Generated artifacts preserve more structure than a long inline answer.
+- Related-document evidence can help structured outputs stay connected to source material.

+Current release version: **0.241.183**
+
+Group Workflow Support extends the workflow system into group workspaces so shared teams can create, schedule, run, and monitor repeatable document work against group-owned content.
+
+## User Side
+
+Group members with the right role can open Group Workspaces, select an active group, and use group workflows for shared document analysis. Group workflows can use group agents, merged global agents, group model endpoints, group File Sync sources, manual runs, interval schedules, and changed-file Analyze targets.
+
+## Admin Side
+
+Admins enable group workflows from the workspace workflow settings. They can optionally require group assignment before a group can use workflows and can require group Owners to manage group agents, actions, and workflows when stricter governance is needed.
+
+## Screenshot Placeholder
+
+Add an admin screenshot showing **Enable Group Workflows**, group assignment controls, and owner-only management controls in Admin Settings.
+
+Add a user screenshot showing a Group Workspaces view with the Group Workflows tab, a workflow list, and a New Group Workflow button.
+
+## Why It Matters
+
+Recurring document work often belongs to a team workspace, not one person's personal workspace.
+
+## How to Try It
+
+1. Open **Admin Settings > Workspaces** and enable group workflows.
+2. Optionally require group assignment and select which groups can use the feature.
+3. Open Group Workspaces and select an active group.
+4. Create a workflow, choose a runner, configure the prompt and document action, then run it manually or on a schedule.
+
+## Notes
+
+- Group workflow definitions and run history are scoped by group.
+- Group workflows accept only group-scoped File Sync sources for the active group.

+description: "How Assigned Knowledge, action expansion, reusable identities, voice-assisted drafting, and governance improve agents"
+section: "Latest Release"
+---
+
+Current release version: **0.250.001**
+
+Agents gained Assigned Knowledge, catalog customization, voice-assisted instruction drafting, Databricks, Tableau, Microsoft Graph mail, MCP actions, reusable identities, and better action governance.
+
+## User Side
+
+Users can find agents with clearer catalog metadata, use assigned-knowledge agents for governed sources, and work with actions that use configured reusable identities.
+
+## Admin Side
+
+Admins manage global identities, action-type availability, model endpoint access, agent catalog customization, and advanced actions such as Databricks, Tableau, Graph mail, and MCP.
+
+## Screenshot Placeholder
+
+Replace `/images/latest-release/release_250_agents_actions.png` with a screenshot of assigned knowledge, action setup, reusable identities, agent catalog customization, and governed action availability.
+
+## Why It Matters
+
+Useful agents need both rich capabilities and clear boundaries for data, credentials, and tool execution.
+
+## How to Try It
+
+1. Open the Agents page or a workspace Agents tab.
+2. Review Assigned Knowledge and available actions.
+3. Open workspace or global identities when an action needs reusable credentials.
+
+## Notes
+
+- Stdio MCP transport remains limited to admin-managed global actions because it can launch server-side commands.

+section: "Latest Release"
+---
+
+Current release version: **0.250.001**
+
+SimpleChat now supports governed access to models, agents, and actions. You may see model or agent choices that are different from another user because admins can assign capabilities to individuals, groups, or broader audiences.
+
+## User Side
+
+Model and agent access can now be assigned to specific users or groups, so different people can see the AI capabilities approved for their work.
+
+## Admin Side
+
+Availability may depend on tenant settings, governance policies, workspace scope, action configuration, or admin-managed identities. If you do not see this capability, contact your SimpleChat admin.
+
+## Screenshot Placeholder
+
+Replace `/images/latest-release/release_250_ai_access.png` with a screenshot showing personalized model and agent access in the app.
+
+## Why It Matters
+
+This matters because teams can make powerful AI tools available to the right people without turning every model or agent on for everyone.
+
+## How to Try It
+
+1. Open Chat and review the model and agent pickers to see what is available to you.
+2. If you do not see a model, agent, or action you expected, it may be controlled by an admin governance policy.
+3. Group-scoped agents and models can appear when you are working in an approved group context.

+section: "Latest Release"
+---
+
+Current release version: **0.250.001**
+
+Generated Markdown viewing, inline charts, tabular exports, related-document evidence, generated Office files, per-message export, and conversation PDF or summary export make outputs easier to reuse.
+
+## User Side
+
+Users can inspect generated Markdown, view inline charts, download or promote generated artifacts, export individual messages, and export conversations with summaries or PDF output.
+
+## Admin Side
+
+Admins govern upload capabilities, generated Office tool availability, workspace promotion approval behavior, and export-related storage and retention paths.
+
+## Screenshot Placeholder
+
+Replace `/images/latest-release/release_250_artifacts_exports.png` with a screenshot of generated Markdown, inline charts, tabular exports, generated Office files, workspace promotion, summaries, and PDF export.
+
+## Why It Matters
+
+Important results should not be trapped in a single chat bubble when users need a document, chart, spreadsheet-style output, or reusable workspace artifact.
+
+## How to Try It
+
+1. Ask Chat for a chart, Markdown artifact, tabular export, or document output.
+2. Use View, Download, Add to Workspace, or message-level export actions.
+3. Export a conversation as Markdown, JSON, or PDF when a full handoff is needed.
+
+## Notes
+
+- Large tabular outputs can stay conversation-scoped as downloadable artifacts instead of flooding the visible answer.

+section: "Latest Release"
+---
+
+Current release version: **0.250.001**
+
+Assigned Knowledge lets agent creators define the search scope an agent should use. When you select an assigned-knowledge agent in Chat, workspace search is enforced and the relevant scope controls become read-only.
+
+## User Side
+
+Agents can be bound to specific workspace sources, documents, and tags so they answer from the knowledge selected for their role.
+
+## Admin Side
+
+Availability may depend on tenant settings, governance policies, workspace scope, action configuration, or admin-managed identities. If you do not see this capability, contact your SimpleChat admin.
+
+## Screenshot Placeholder
+
+Replace `/images/latest-release/release_250_assigned_knowledge.png` with a screenshot showing assigned knowledge for agents in the app.
+
+## Why It Matters
+
+This matters because specialized agents can stay focused on the knowledge they were designed to use.
+
+## How to Try It
+
+1. Use assigned-knowledge agents when you need a purpose-built assistant for a known document set.
+2. Review the knowledge context shown in Chat when an assigned-knowledge agent is selected.
+3. Agent creators can configure workspace sources, documents, tags, and available actions during setup.

+
+1. Paste copied images or files into Chat, or drag files into the chat input when uploads are enabled.
+2. Review upload progress in the conversation while workspace processing continues.

+section: "Latest Release"
+---
+
+Current release version: **0.250.001**
+
+Governance policies now cover endpoints, agents, actions, feature access, delegated item review, and action-type availability across personal, group, and global scopes.
+
+## User Side
+
+Users see only the governed endpoints, agents, actions, and action types their account or group is allowed to use. Delegated personal or group items can follow review workflows before broader use.
+
+## Admin Side
+
+Admins manage feature policies, delegated item policies, review workflows, allowlists, and action-type controls from Admin Settings governance surfaces.
+
+## Screenshot Placeholder
+
+Replace `/images/latest-release/release_250_governance.png` with a screenshot of feature policies, endpoint/agent/action policy controls, delegated review, and action-type governance.
+
+## Why It Matters
+
+Broader AI capabilities need a reviewable access model that scales beyond one global on/off switch.
+
+## How to Try It
+
+1. Open **Admin Settings > Governance**.
+2. Review feature policies for endpoints, agents, actions, and action types.
+3. Confirm the user-facing picker only shows allowed items.
+
+## Notes
+
+- Governance cache versioning reduces stale reads after admin policy changes across Redis-enabled and no-Redis deployments.

+section: "Latest Release"
+---
+
+Current release version: **0.250.001**
+
+Group file sharing adds notifications, approval decisions, and safer ownership boundaries so shared files can move between groups without giving the receiving group control over the source document.
+
+## User Side
+
+Users can share personal or group documents with groups, and receiving groups can approve shared files before they become searchable.
+

+
+Replace `/images/latest-release/release_250_group_file_sharing.png` with a screenshot showing group file sharing and approvals in the app.
+
+## Why It Matters
+
+This matters because collaboration often crosses workspace boundaries, but shared documents still need review and clear ownership.
+
+## How to Try It
+
+1. Share documents with groups when a file should be available to another team.
+2. Receiving group owners, admins, or document managers can approve or remove shared files.
+3. Watch notifications for share requests, approvals, and denials.

+description: "Users can now apply multiple selected-text masks to the same message, including shared personal and group conversations."
+section: "Latest Release"
+---
+
+Current release version: **0.250.001**
+
+Mask-plus and mask-minus controls let you layer selected-text masks independently from full-message masks. In collaborative conversations, masking metadata follows shared event updates while display names are bound to the authenticated user.
+
+## User Side
+
+Users can now apply multiple selected-text masks to the same message, including shared personal and group conversations.
+
+## Admin Side
+
+Availability may depend on tenant settings, governance policies, workspace scope, action configuration, or admin-managed identities. If you do not see this capability, contact your SimpleChat admin.
+
+## Screenshot Placeholder
+
+Replace `/images/latest-release/release_250_layered_masking.png` with a screenshot showing layered message masking in the app.
+
+## Why It Matters
+
+This matters because users can hide multiple sensitive ranges in a message without losing control over previous masks.
+
+## How to Try It
+
+1. Use selected-text masking when only part of a message needs to be hidden.
+2. Use full-message masking when the entire message should be covered.
+3. Layered masks can be managed independently so one mask can be removed without clearing all others.

+
+Model endpoint setup guidance, global and workspace endpoint management, provider-aware Foundry routing, Claude-capable deployments, and model icon avatars make model choices clearer across Chat, agents, workflows, and generated summaries.
+
+## User Side
+
+Users choose from the model picker and see model-only assistant responses with clearer visual identity when endpoint icons or uploaded model images are configured. Agent responses keep agent avatar priority.
+

+
+## How to Try It
+
+1. Open **Admin Settings > AI Models** and review endpoint setup guidance.
+2. Configure or inspect a model endpoint icon or uploaded model image.
+3. Open Chat and select an available model from the model picker.

+
+## How to Try It
+
+1. Ask Chat to create multiple related images in one request when you need a set of options, variations, or supporting visuals.

+
+Current release version: **0.250.001**
+
+Visio ingestion indexes diagram pages and supports citation previews. Outlook MSG ingestion lets saved email files participate in the document processing pipeline so conversations can reason over email content and metadata.
+
+## User Side
+
+Users can upload Visio `.vsdx` diagrams and Outlook `.msg` email files so more everyday work artifacts can become searchable knowledge.
+
+## Admin Side
+
+Availability may depend on tenant settings, governance policies, workspace scope, action configuration, or admin-managed identities. If you do not see this capability, contact your SimpleChat admin.
+
+## Screenshot Placeholder
+
+Replace `/images/latest-release/release_250_visio_msg_ingestion.png` with a screenshot showing visio and outlook msg file support in the app.
+
+## Why It Matters
+
+This matters because architecture diagrams, process diagrams, and email files often contain important context that should not be trapped outside workspace search.
+
+## How to Try It
+
+1. Upload `.vsdx` diagrams when shapes, pages, and connectors should become searchable.
+2. Upload `.msg` files when saved Outlook email needs to be processed as workspace knowledge.
+3. Use enhanced citations to inspect previews or original files where supported.

+
+This matters because many setup and metadata fields are easier to draft by voice, especially longer agent instructions or document descriptions.
+
+## How to Try It
+
+1. Look for microphone controls beside supported form fields.
+2. Use dictated instruction briefs to draft agent instructions, then review and edit before saving.
+3. Expect this pattern to expand to more form fields over time.

+
+Personal and group workflows gained File Sync triggers, monitor-for-changes mode, per-document Analyze runs, resume-failed batches, activity views, and generated Office exports.
+
+## User Side
+
+Users can run personal or group workflows, refresh selected File Sync sources before a run, monitor changed files, and resume failed document items from a previous Analyze batch.
+
+## Admin Side
+
+Admins control personal workflow enablement, WorkflowUser role enforcement, group workflow enablement, group assignment, File Sync source types, connector identities, and workspace scope gates.

+1. Open **Personal Workspace > Workflows** or **Group Workspaces > Workflows**.
+2. Create or edit a workflow and enable File Sync Before Run.
+3. Review run history and activity after execution.
+
+## Notes

+section: "Latest Release"
+---
+
+Source Review adds a governed evidence-review layer for URLs and web-search citations before the assistant prepares a final answer.
+
+## User Side
+
+Users can open source tools in Chat, ground a prompt in workspace sources, and use Source Review or Deep Research when URLs or web evidence should be inspected before the final answer.
+
+## Admin Side
+
+Admins configure Source Review, Deep Research, rendering, page budgets, and allow/block controls from **Admin Settings > Search & Extract**. The screenshots show both the policy controls and the user chat surfaces they govern.
+
+## Why It Matters
+
+Users can ground answers in reviewed source-page evidence instead of depending only on snippets or unsupported browsing assumptions.
+
+## How to Try It
+
+1. Ask a web-grounded question in Chat and enable the **Sources** experience when available.
+2. Paste URLs or use Web Search citations that should be reviewed before the final answer.
+3. Use Deep Source Review when bounded source traversal is helpful for archives, press-release lists, or official source indexes.
+4. Admins can tune allowlists, blocklists, page budgets, rendering, and access controls from **Search & Extract**.
+
+## Notes
+
+- Source Review treats fetched pages as untrusted evidence.
+- Deep traversal remains bounded by admin-controlled budgets and safety checks.
+- JavaScript rendering and Load More hydration are optional because they add runtime cost.

+Profile, Stats, and Preferences turns the profile page into the user's control center for personal usage, saved preferences, workspace membership, support feedback, and violation follow-up.
+
+## User Side
+
+Users can open Profile to review richer account details, choose 7-day, 30-day, 90-day, or custom activity windows, and export visible metrics for offline analysis. The same page also gives users control over navigation preferences, tutorial visibility, retention settings, saved instructions and facts, speech preferences, and text-to-speech voice selection.
+
+Profile also gives users a single place to see groups, public workspaces, submitted feedback, and safety violations without jumping through separate admin or support pages.
+
+## Screenshot Placeholders
+
+- Profile Stats: capture the reporting window controls, custom range, export button, and activity charts.
+- Profile Settings: capture navigation preferences, tutorial preferences, Fact Memory, retention settings, speech controls, and text-to-speech voice selection.
+- Profile Workspace Tabs: capture Groups and Public Workspaces tabs showing membership and owned workspace details.
+- Profile Support Tabs: capture Feedback and Violations tabs with filters, summaries, export controls, and detail modals.
+
+## Why It Matters
+
+Users can understand their own activity and tune their everyday app experience without asking an admin to change global settings.
+
+## How to Try It
+
+1. Open Profile > Stats and choose a 7-day, 30-day, 90-day, or custom reporting window.
+2. Export the visible activity metrics when you need offline reporting.
+3. Open Profile > Settings and review navigation, tutorial, memory, retention, speech, and text-to-speech voice preferences.
+4. Open Profile > Groups and Profile > Public Workspaces to review workspace membership and ownership.
+5. Open Profile > Feedback and Profile > Violations to review submitted feedback, safety violation history, filters, exports, and detail views.
+
+## Notes
+
+- Date windows and CSV exports remain available from Profile stats.
+- Text-to-speech voice selection appears in Profile settings when voice responses are enabled for the environment.
+- Groups, public workspaces, feedback, and violations stay scoped to what the signed-in user is allowed to see.

+section: "Latest Release"
+---
+
+Visio Ingestion parses `.vsdx` files into searchable diagram page content and provides lightweight citation previews from the built-in structural renderer.
+
+## User Side
+
+Workspace users can upload `.vsdx` diagrams, find them in the document list, ask chat questions about pages, labels, shapes, and connectors, and open citation previews or the original file when needed.
+
+## Admin Side
+
+Admins enable the document-processing and enhanced-citation capabilities that make Visio files searchable and previewable in supported workspaces.
+
+## Why It Matters
+
+Architecture and process diagrams become searchable knowledge instead of opaque attachments.
+
+## How to Try It
+
+1. Upload a `.vsdx` file to a supported workspace.
+2. Wait for indexing to complete, then ask questions about diagram pages, shapes, labels, and connectors.
+3. Open enhanced citations to inspect the rendered Visio page preview.
+4. Download the original `.vsdx` when exact desktop rendering is needed.
+
+## Notes
+
+- The preview renderer focuses on useful citation inspection, not full Visio desktop fidelity.
+- The original `.vsdx` remains available for exact inspection when supported by the workspace.
+- Visio citations depend on enhanced citation and document processing availability.

+---
+
+Current release version: **0.241.183**
+
+Workflow Automation connects personal and group workflows to File Sync sources, access governance, dynamic document targeting, and batch resume behavior.
+
+## User Side
+
+Workflow users can create and monitor personal workflows from Personal Workspace and group workflows from Group Workspaces when the feature is enabled for their group. Workflows can trigger File Sync before a run starts and can target changed synced files for Analyze steps.
+
+## Admin Side
+
+Admins enable personal workflows, optionally require the `WorkflowUser` Enterprise App role, enable group workflows, assign group workflow access to selected groups, and control File Sync before-run automation. The screenshot gallery pairs those admin settings with the user workflow list and editor controls.
+
+## Screenshot Placeholder
+
+Add a screenshot showing the group workflow enablement controls beside personal workflow controls in Admin Settings.
+
+Add a group-side screenshot showing a group workflow list with group File Sync sources available in the workflow editor.
+
+## Why It Matters
+
+Repeatable document analysis can run when source files change rather than waiting for someone to manually refresh and restart every item.
+
+## How to Try It
+
+1. Open Personal Workspace or Group Workspaces and review workflow availability in your environment.
+2. Configure a workflow to run selected personal or group File Sync sources before the workflow prompt executes.
+3. Use monitor-for-changes mode when the workflow should run only after synced files change.
+4. Resume failed document items from workflow run history when a batch analysis partially fails.
+
+## Notes
+
+- Admins can require a dedicated WorkflowUser Enterprise App role.
+- Admins can enable group workflows and optionally assign the feature to selected groups.
+- Analyze workflows can target changed synced documents dynamically.
+- Per-document run tracking makes batch failures easier to retry without rerunning everything.

+
+Workspace Experience updates make personal, group, and public workspaces easier to scan, brand, and govern.
+
+## User Side
+
+Workspace users can switch between list, cards, folders, and folders-plus-cards views, scan badges and document actions, chat with individual documents, and use branding cues to confirm the active workspace.
+
+## Admin Side
+
+Admins control which workspace types and document features are enabled, while group and public workspace owners configure shared branding such as hero colors and logos. The screenshots show both user browsing views and owner-managed branding controls.
+
+## Custom Workspace Hero Colors
+
+Group and public workspace owners can now choose from preset hero colors or use the custom color swatch on the manage page. The selected color updates the hero preview before saving, making it easier to confirm shared workspace branding.

+
+## Why It Matters
+
+Document-heavy spaces need fast scanning, clear ownership context, and predictable approval workflows when content moves between teams.
+
+## How to Try It
+
+1. Open a workspace document list and switch between list, card, folder, and folder-card views.
+2. Review group and public workspace hero areas to confirm the active workspace context.
+3. Use manage pages to configure colors, logos, and workspace branding when you own the workspace.
+4. Watch for approval notifications when shared files or generated artifacts need review.
+
+## Notes
+
+- Available views can vary by workspace type and enabled settings.
+- Branding helps users confirm which shared workspace they are working in.
+- Custom hero colors are stored as normalized `#RRGGBB` values and use the same manage-page save flow as other workspace details.
+- Approval flows keep shared and public knowledge from becoming searchable before review.

+## Code-only upgrades
+
+For container-only releases where infrastructure does not change, use `upgrade-simplechat.ps1`.
+
+This script builds the image in ACR, updates the current App Service container image, verifies the updated image reference, and restarts the site. It gives the Azure CLI deployer a PowerShell-first equivalent to the normal `azd deploy` container rollout path without invoking the AZD post-configuration Python flow.
+
+Example:
+
+```powershell
+cd deployers/azurecli
+./upgrade-simplechat.ps1 `
+	-AcrName registrysimplechatprod `
+	-ImageName simplechat:2026-04-29_01 `
+	-BaseName contoso `
+	-Environment prod

+"""
+Functional test for chat upload personal workspace handoff.
+Version: 0.241.209
+Implemented in: 0.241.203; expanded in: 0.241.207, 0.241.208, and 0.241.209
+
+This test ensures chat uploads are wired to queue personal workspace documents,
+replace eligible chat-local file processing with workspace-backed messages,
+automatically search ready linked workspace documents, display processing
+progress, enable the user workspace context as soon as workspace processing
+starts, auto-select the completed workspace document, and warn on
+conversation-linked workspace document deletion. It also
+validates selectable linked-document deletion from the conversation delete modal,
+including when conversation archiving is enabled,
+duplicate workspace filename isolation for repeated chat uploads, and clean
+workspace tagging that keeps conversation IDs in metadata instead of tags. It
+also validates that chat upload progress can refresh from the workspace document
+and that assigned-knowledge chats treat ready linked uploads as explicit
+conversation task documents for allowed Search and Analyze actions. It also
+validates that assigned knowledge stays separate from task documents, is searched
+as top-12 reference context for Search, Analyze, and Compare, and does not let
+Search answer from assigned knowledge alone while uploaded task documents are
+still processing. It also validates that auto-linked uploads cannot broaden
+search into other users' personal workspace documents and that chat document
+actions cannot use unauthorized group or public workspace scope ids.

-Tests the ability to split large images across multiple Cosmos DB documents.

+Functional tests for inline chart graphics in conversation exports.
+Version: 0.241.143
+Implemented in: 0.241.139
+
+This test ensures simplechart blocks are converted to PNG-backed export content
+for Markdown/PDF, Word, and PowerPoint export flows instead of leaking code,
+while preserving explicit chart colors. It also ensures approved simpleimage
+proposal results are converted to Word-embedded PNG media.

+Functional test for Cosmos throughput autoscale decision logic.

+Enhanced in: 0.241.183 with detailed access validation diagnostics for partial Azure permission failures.
+Enhanced in: 0.241.184 with neutral container-targeted throughput status language.
+Enhanced in: 0.241.194 with dedicated container scale-up-to-max coverage when mixed database and container throughput exist.
+Enhanced in: 0.241.199 with SimpleChat's 10,000 RU/s scaling support ceiling and portal-managed monitoring coverage.
+
+This test ensures that Cosmos DB throughput automation scales the shared
+SimpleChat database up and down using separate thresholds, cooldowns, and
+minimum/maximum RU guardrails without requiring live Azure resources. It also
+validates enforced global container policy behavior for current and future
+containers, including optional conversion from manual throughput to native
+Cosmos autoscale throughput.

+Functional test for Data Management security patterns.

+Implemented in: 0.241.211
+Updated in: 0.241.231

+This test ensures Data Management admin routes require authenticated admin
+access, secrets stay redacted in frontend responses, and the admin browser
+controller avoids XSS-prone rendering sinks. It also verifies the migration

+"""
+Functional test for Foundry delegated user authentication.
+Version: 0.241.196
+Implemented in: 0.241.185
+
+This test ensures that Foundry agents and workflows default to signed-in user
+Foundry access, preserve delegated auth through payload sanitization, and do
+not inherit saved model endpoint managed identity, service principal, or API-key
+secrets unless an agent explicitly opts into supported Entra service modes.
+
+The Foundry auth-required stream rendering regression was added in 0.241.186.
+Foundry workflow agent-reference support was added in 0.241.192.
+Foundry agent/workflow API-key invocation was restricted to Entra/RBAC in 0.241.196.

+"""
+Functional test for Foundry workflow agent payload support.
+Version: 0.241.196
+Implemented in: 0.241.127
+
+This test ensures that generic Foundry workflow agents can be validated,
+normalized, and stored without hardcoded workflow names. It also verifies
+that Foundry agents discovered from the project agents API can be invoked
+through the workflow agent_reference path. API-key workflow invocation is
+rejected because Foundry agents and workflows require Entra/RBAC access.

  - Happy path: Word document built successfully from a valid message.
  - Word-native formatting: markdown content is converted into DOCX headings, lists, tables, and styled runs.
  - Email export: mailto drafts use word-style plain text and smarter subject selection.
+ - Email chart export: inline charts are converted to PNG download payloads for mail drafts.
+ - Edited chart export: frontend chart color edits are sent to backend export routes.
  - Markdown export logic: correct header, timestamp and content rendered.
  - Route regression: backend source defines POST /api/message/export-word.
  - Auth failure: unauthenticated caller receives 401.

+Functional test for per-message PowerPoint export.
+Version: 0.241.146
+Implemented in: 0.241.033
+
+This test ensures the message export flow exposes a PowerPoint route,
+uses the frontend PowerPoint action hook, prefers the message model
+deployment for AI slide planning, and produces a valid .pptx deck with
+appendix slides for visuals, tables, code, and references. It also
+ensures already structured markdown slide decks are exported without
+AI summarization or slide-count compression. It also ensures generated
+Markdown artifacts can be used as the PowerPoint export source and that
+slide-local charts/images render as PNGs without leaking authoring labels.
+It also verifies edited assistant markdown can be sent with direct message exports.

+Functional test for public workspace dropdown access and search.

+Functional test for Source Review security and evidence extraction.
+Version: 0.241.083

+Updated in: 0.241.072; 0.241.079; 0.241.081; 0.241.082; 0.241.083
+
+This test ensures that Source Review applies access controls, clamps admin limits,
+blocks unsafe URLs, extracts bounded HTML evidence and structured archive rows,
+hydrates dynamic-grid archive JSON, ignores missing date containers, validates
+shared URL Access policy, tolerates nested removed HTML nodes, and uses optional
+app-role access without trusting page text as instructions.

+Functional test for workspace branding hero and logo support.
+Version: 0.241.177
+Implemented in: 0.241.125
+
+This test ensures that group and public workspace branding metadata, logo
+endpoints, and hero UI hooks remain wired across the backend routes, manage
+pages, and active workspace pages. Updated in 0.241.146 to validate that active
+workspace hero cards render before page selectors without redundant headings.
+Updated in 0.241.150 to validate compact public workspace selector controls.
+Updated in 0.241.151 to validate public workspace dropdown search wiring.
+Updated in 0.241.152 to keep public workspace search visible for any list size.
+Updated in 0.241.176 to validate custom hero color swatches for group and
+public workspace manage pages.

+Version: 0.241.199
+Implemented in: 0.241.147
+
+This test ensures the Scale tab exposes Cosmos throughput monitoring and
+separate scale-up/scale-down automation controls with min and max guardrails.
+It also validates the container-targeted metric clarity, setup guide UI, and
+cached status first render. Container policy enforcement coverage was added in
+version 0.241.153. Aggregate-only metric warning coverage was added in
+version 0.241.154 and clarified in version 0.241.155. Version 0.241.156
+keeps coverage aligned with the REST metadata metrics path. Version 0.241.157
+adds Metrics Window cadence copy coverage. Version 0.241.159 adds native
+Cosmos manual-to-autoscale conversion coverage. Version 0.241.161 adds
+grouped scale-up/scale-down policy UI and save-blocking validation coverage.
+Version 0.241.162 adds Validate Access setup testing coverage.
+Version 0.241.180 adds container table sorting and filtering coverage.
+Version 0.241.181 adds container table refresh button coverage.
+Version 0.241.183 adds explicit setup guidance and detailed Validate Access diagnostics coverage.
+Version 0.241.184 adds neutral informational copy for normal container-targeted throughput mode.
+Version 0.241.199 adds SimpleChat's 10,000 RU/s scale support ceiling, monitor-only indicators, and container policy modal filtering coverage.

+UI test for chat document action selector labels.
+Version: 0.241.030
+Implemented in: 0.241.030
+
+This test ensures the chat document action selector renders before scope,
+uses the Search/Analyze/Compare labels, updates the hover description for
+each selected action, keeps the Document picker full width for every action,
+and exposes the compact Source/Target comparison summary as a full-width row
+below the dropdowns plus the modal editor with both version history and
+uploaded chat files.

+UI test for analysis streaming thought progress.

+
+This test ensures the streaming thought placeholder keeps the overall
+progress bar below 100 percent while the final reduction step is still
+running, even after the per-document analysis bars have completed, and

+UI test for inline Azure Maps rendering in chat.
+Version: 0.241.116
+Implemented in: 0.241.053; local asset validation updated in 0.241.116
+
+This test ensures that assistant messages can hydrate an Azure Maps agent
+citation artifact, render the inline map card inside the chat bubble, and keep
+the standard citation button available for the same tool invocation while
+fitting the full visible feature set after the visualization container is shown
+without loading OpenLayers from a CDN.

+"""
+UI test for inline chart rendering in chat.
+Version: 0.241.146
+Implemented in: 0.241.047; YAML and pending-source rendering fixed in 0.241.126; final metadata rendering fixed in 0.241.134; streaming chart stability fixed in 0.241.141; chart color editor added in 0.241.145; edited chart export override added in 0.241.146
+
+This test ensures that assistant messages can render inline Chart.js visualizations
+in the chat page, that the optional data table is accessible in desktop and mobile layouts,
+that YAML-style chart blocks do not leak raw chart source while streaming, and that
+final assistant metadata rendering does not blank hydrated chart canvases. It also
+validates the chart-level color editor updates rendered charts without creating a new message
+and that exports send the edited chart markdown to the backend.

+"""
+UI test for assistant inline export action buttons.
+Version: 0.241.179
+Implemented in: 0.241.179
+
+This test ensures assistant replies show inline export buttons when the latest
+user prompt explicitly asks for a supported export format such as a
+presentation, markdown document, or email, that the buttons persist when the
+conversation history is reloaded, that inline create actions show a pending
+label while the export is being prepared, and that PowerPoint exports prefer
+attached generated Markdown artifacts when present. It also ensures streaming
+assistant placeholders do not expose export/create actions before the final
+message is available, and that generic email export buttons are suppressed when
+Microsoft Graph already provides the real mail action or consent prompt. It also
+verifies the consent prompt includes a test-access action.
