**Phase 11 PAUSED** - Chat feature implementation complete, pending final UAT.

**What got done this session (2026-02-02):**
1. ✅ Fixed chat message bugs (commits 99f9d4b, f3044a29, 939225a, 5132c8345)
   - "Unknown" sender name → Fixed API response format and Redux handling
   - First message not appearing → Added optimistic update parameters
   - WebSocket messages not received → Added callback handler with correct signature
   - client_id not passed → Backend now excludes sender from broadcast correctly

2. ✅ Fixed audio profile bugs (commits 970bbe3e, cff2c047, 332ae61b, 010cf553)
   - Missing await on GetClientID() → Fixed Promise handling
   - JK.AlertCallback not found → Added alias for native client
   - Profile guard rejecting with undefined → Proper error objects
   - Redirect to non-existent route → Alert + redirect to dashboard

3. ⏳ Chat multi-user testing INCOMPLETE
   - WebSocket handler added but not fully tested
   - Badge updates not verified
   - Need complete UAT with two real users

**Status:**
- Chat code is functionally complete
- Several critical bugs fixed (send, receive, WebSocket, audio profile)
- Ready for comprehensive UAT but paused per user request
- Will resume UAT and fix any issues found later
</current_state>

## Phase 11: Chat Finalization

### Plan 11-01: Error Handling, Accessibility & Polish ✅ COMPLETE
- Comprehensive error handling (red/yellow displays, retry button)
- Full accessibility (ARIA attributes, keyboard navigation, focus management)
- Edge case handling (empty states, validation, disconnection)

### Plan 11-02: UAT & Final Integration Testing ⏸️ PAUSED
- Task 1: ✅ UAT checklist prepared (50+ test cases across 9 categories)
- Task 2: ✅ Multiple P0 bugs fixed:
  - session_id → music_session parameter (commit 5b940ae)
  - "Unknown" sender name (commits 2b593cc, 6dc6c43, 99f9d4b)
  - Message format handling (commit 99f9d4b)
  - WebSocket callback registration (commits f3044a29, 939225a)
  - client_id parameter (commit 5132c8345)
- Task 3: ⏸️ Manual UAT - NOT STARTED (paused per user request)

### Bonus: Audio Profile Bug Fixes ✅ COMPLETE
- Fixed session join errors with MacBook built-in audio
- GetClientID() Promise handling (commit 970bbe3e)
- JK.AlertCallback native client integration (commit cff2c047)

- Phase 10: Read/Unread Status Management (1/1 plans)
</completed_work>

## Immediate: Complete Chat UAT (When Resumed)

**Priority:** P1 - Paused for now, resume later

**UAT Test Scenarios:**
1. Multi-user message exchange (2 browser windows, different users)
   - User A sends → User B receives via WebSocket ✓
   - User B sends → User A receives via WebSocket ✓
   - Sender names display correctly ✓
   - Message text displays correctly ✓

2. Badge updates
   - Window closed → unread count increments ✓
   - Window opened → badge resets to 0 ✓
   - Page refresh → badge persists from localStorage ✓
   - Multiple messages → count accumulates ✓

3. Complete UAT checklist (50+ test cases)
   - Chat Button & Badge (visibility, counts, interaction)
   - Chat Window (open/close, drag, position persistence)
   - Message Display (rendering, timestamps, scrolling)
   - Message Sending (validation, keyboard shortcuts)
   - Message Receiving (WebSocket, deduplication, auto-scroll)
   - Read/Unread Status (badge updates, persistence, multi-channel)
   - Error Handling (network errors, validation, retry)
   - Accessibility (ARIA labels, keyboard navigation)
   - Edge Cases (disconnection/reconnection, rapid sending)

4. Fix any issues found during UAT

## After UAT Complete: Ship Milestone v1.1

- Update STATE.md with "Phase 11 COMPLETE"
- Update ROADMAP.md progress table
- Verify all verification criteria met
- Mark milestone v1.1 as SHIPPED

## TODOs for Future Work

### TODO: JKSessionProfileDialog Component
**Priority:** P2 - Improves UX but not blocking

**Current state:**
- When audio profile check fails (canPlayWithOthers = false)
- Shows JavaScript alert() → kicks user to dashboard
- Works but not user-friendly

**Desired state (match legacy app):**
- Show modal dialog with 3 options:
  1. "Create Private Session" → Create solo practice session, redirect there
  2. "Go to Audio Settings" → Redirect to /account/audio to fix profile
  3. "Cancel" → Return to dashboard

**Reference:**
- Legacy: `web/app/assets/javascripts/wizard/gear_utils.js` line 484+
- Legacy dialog: `single-player-profile-dialog`

**Files to modify:**
- Create: `jam-ui/src/components/client/JKSessionProfileDialog.js`
- Update: `jam-ui/src/components/client/JKSessionScreen.js` (replace alert)
- Update: `jam-ui/src/hooks/useGearUtils.js` (show dialog, handle options)

**Acceptance criteria:**
- Dialog appears when profile check fails
- All 3 options work correctly
- Proper error.controlled_location handling
- Matches legacy app behavior
</remaining_work>

<decisions_made>
## Phase 11 Decisions

1. **Pause chat UAT**: User requested to pause chat feature work, will resume later for full UAT
2. **Debug logging added**: Console logs added to WebSocket handler for future debugging
3. **Alert instead of dialog**: For audio profile issues, show alert() temporarily (TODO: proper modal)
4. **Fixed multiple critical bugs**: All known P0 bugs fixed before pausing

## Bug Fix Decisions

1. **WebSocket callback signature**: Use (fullMessage, payload) where payload contains actual data
2. **client_id parameter**: Must be passed to backend to exclude sender from broadcast
3. **Audio profile handling**: Mimic legacy behavior (alert + redirect) until proper dialog implemented
4. **GetClientID Promise**: Must await before use, was causing [object Promise] in URLs

## Investigation Scope

**In scope (completed):**
- Chat message send/receive bugs
- WebSocket integration
- Audio profile session join issues
- Native client callback integration

**Out of scope (deferred):**
- Test infrastructure fixes (Playwright timeout issues)
- Server-side read/unread tracking
- File attachments, message editing, typing indicators
- Other deferred features from Phase 6 design
- Profile dialog modal (TODO for later)
</decisions_made>

## Mental State

**What we did this session:**
- Started debugging multi-user chat (messages not flowing between users)
- Found and fixed 4 different issues with chat WebSocket integration
- User discovered audio profile bug with built-in MacBook audio
- Fixed 4 additional bugs related to audio profile handling
- Documented legacy app behavior for future dialog implementation
- Paused chat work per user request for later UAT

**The vibe:**
- Lots of bug fixing and debugging
- Chat feature is much more complete now
- Audio profile handling improved significantly
- Good progress but incomplete testing
- Ready to resume UAT whenever needed

**Key insights:**
1. WebSocket callbacks get (fullMessage, payload) - must use payload
2. Backend needs client_id to filter sender from broadcast
3. Optimistic updates need userId, userName, optimisticId
4. Legacy app shows helpful dialogs we should replicate
5. Built-in audio profiles fail canPlayWithOthers() check

## Technical Context

- `jam-ui/src/hooks/useGearUtils.js` - Proper error objects
- `jam-ui/src/components/client/JKSessionScreen.js` - AlertCallback alias, alert handling

**Files with debug logging:**

**When resuming chat UAT:**

1. **Remove debug logging** (optional):
   - Clean up console.log statements in JKSessionScreen.js handleChatMessage
   - Or keep for UAT debugging

2. **Start multi-user testing:**
   - Open two browser windows (different users)
   - Both join same session
   - Test message exchange in both directions
   - Verify badge updates work correctly
   - Check console for any errors

3. **Complete full UAT checklist:**
   - 50+ test cases across 9 categories
   - Document any issues found
   - Fix any P0/P1 bugs discovered
   - Verify all edge cases

4. **Ship milestone v1.1:**
   - Update STATE.md
   - Update ROADMAP.md
   - Mark milestone as SHIPPED

**Command to resume:**
```
Let's resume the chat UAT. I'm ready to test multi-user chat with two browser windows.
