Phase 11 (Chat Finalization) Plan 1 is COMPLETE. Plan 2 (UAT & Final Integration Testing) is ready to execute.

This is the LAST plan of Phase 11, which is the LAST phase of the v1.1 Music Session Chat milestone.

After completing Plan 11-02, the entire milestone will be complete.

</completed_work>

**Phase 11 Plan 2 (11-02): UAT & Final Integration Testing**

This plan conducts comprehensive user acceptance testing across 50+ test cases in 9 categories:
1. Initialization & Window Management (6 tests)
2. Message Display & Formatting (5 tests)
3. Message Composition & Sending (8 tests)
4. Message Receiving (WebSocket) (5 tests)
5. Read/Unread Tracking (7 tests)
6. Error Handling (6 tests)
7. Performance (4 tests)
8. Accessibility (5 tests)
9. Edge Cases (4 tests)

Expected tasks (from plan structure):
- Task 1: Run comprehensive UAT test suite (manual or automated via Playwright)
- Task 2: Fix any critical (P0/P1) issues found
- Task 3: Document deferred issues and complete milestone documentation

After Plan 11-02 completes:
- Phase 11 will be complete (2/2 plans)
- v1.1 Music Session Chat milestone will be complete
- Ready for `/gsd:complete-milestone`
</remaining_work>

<decisions_made>
**From Plan 11-01:**
- Error color coding: Red (#dc3545) for critical (send failures), Yellow (#fff3cd) for warnings (disconnection)
- ARIA approach: aria-modal="false" for modeless WindowPortal dialog
- Focus timing: 100ms delay for textarea auto-focus to ensure DOM readiness
- Escape key: Global window listener (not scoped to dialog)
- Retry pattern: Clear error and re-enable input, don't auto-resend (prevents duplicates)

**Architectural patterns established across v1.1:**
- WindowPortal for modeless dialogs (chat window)
- Redux Toolkit with async thunks
- WebSocket Protocol Buffer integration
- localStorage for client-side persistence (lastReadAt timestamps)
- Color-coded error displays (red/yellow)
- ARIA accessibility patterns
- TDD for data layer (100% coverage for Redux/API/WebSocket)
</decisions_made>

<blockers>
None. All systems operational.

**Note:** There are some uncommitted changes in working directory:
- .gitignore (modified)
- jam-ui/test/storageState/user1.json (modified)
- jam-ui/test/storageState/user2.json (modified)
- run-claude.sh (untracked)

These are unrelated to chat work and should be ignored or committed separately.

**Session progression:**
Phase 11 Plan 1 was executed using Strategy A (fully autonomous - no checkpoints). A subagent executed all 3 tasks, created atomic commits per task, and generated the SUMMARY.md. The main orchestrator updated STATE.md and ROADMAP.md and committed the metadata.

**Chat feature status:**
The chat feature is now production-ready with:
- ✅ Complete Redux state management (Phases 7-9)
- ✅ Full UI implementation (Phases 8-9)
- ✅ Read/unread tracking with localStorage (Phase 10)
- ✅ Comprehensive error handling (Phase 11 Plan 1)
- ✅ Full accessibility support (Phase 11 Plan 1)
- ✅ Edge case handling (Phase 11 Plan 1)

**What's left:**
Only UAT validation (Plan 11-02) remains before milestone completion.

**Milestone context:**
- v1.0 (Phases 1-5): Backing Track + JamTrack players - COMPLETE
- v1.1 (Phases 6-11): Music Session Chat - 90% complete (10/11 plans done)

**Progress:**
- Phase 6 (Research): 2/2 plans ✅
- Phase 7 (Infrastructure): 3/3 plans ✅
- Phase 8 (UI): 3/3 plans ✅
- Phase 9 (Composition): 2/2 plans ✅
- Phase 10 (Unread): 1/1 plans ✅
- Phase 11 (Finalization): 1/2 plans ✅ ← YOU ARE HERE

**Deferred features (documented in ISSUES.md):**
- Server-side read/unread tracking (cross-device sync)
- File attachments
- Message editing/deletion
- Typing indicators
- Emoji picker
- Multi-channel tabs UI
- Message search/filtering
- Desktop notifications

<next_action>
**To resume:**

1. Run `/clear` to start fresh session
2. Run `/gsd:execute-plan .planning/phases/11-chat-finalization/11-02-PLAN.md`

The plan will execute UAT testing, fix any critical issues found, and complete milestone documentation.

After Plan 11-02 completes, you'll need to:
1. Run `/gsd:complete-milestone` to archive v1.1 and prepare for next work
2. Consider creating v1.2 milestone or addressing deferred issues

**Alternative:**
If you want to manually test the chat before running automated UAT, you can:
1. Start the development environment (jam-ui + web + websocket-gateway)
2. Open http://beta.jamkazam.local:4000
3. Join a session and test chat functionality manually
4. Then run Plan 11-02 for automated validation
