<task type="auto">
  <name>Task 1: Prepare UAT test checklist and run automated tests</name>
  <files>None (testing only)</files>
  <action>Prepare comprehensive UAT and run existing automated test suites:

**Step 1: Run existing Playwright tests**
```bash
cd jam-ui
npm test -- test/chat/*.spec.ts
```
Expected results:
- chat-window.spec.ts: 3 tests passing
- send-message.spec.ts: 7 tests passing
- receive-message.spec.ts: 4 tests passing
- unread-badge.spec.ts: 8 tests passing
- localStorage-persistence.spec.ts: 7 tests passing
- chat-button.spec.ts: tests passing

**Step 2: Document UAT test plan**
Create UAT test plan covering all 9 categories from IMPLEMENTATION_ROADMAP.md. Format as markdown checklist:

**1. Initialization & Window Management (6 tests)**
- [ ] Click chat button → window opens
- [ ] Window displays correct channel name (session ID)
- [ ] Close button closes window
- [ ] Escape key closes window (new in 11-01)
- [ ] Window position persists during session
- [ ] Rapid open/close (10x) doesn't cause errors

**2. Message Display & Formatting (5 tests)**
- [ ] Messages display with avatar, sender name, text, timestamp
- [ ] Timestamps format correctly ("Just now", "5 min ago", "Yesterday", etc.)
- [ ] Empty state shows "No messages yet" before first message
- [ ] Long messages (near 255 chars) wrap properly
- [ ] Multiple messages from same user display correctly

**3. Message Composition & Sending (8 tests)**
- [ ] Textarea accepts input (1-255 chars)
- [ ] Character count displays correctly (X/255)
- [ ] Character count turns yellow at 231 chars
- [ ] Character count turns red at 256+ chars
- [ ] Send button disabled when empty or over limit
- [ ] Enter key sends message
- [ ] Shift+Enter inserts newline
- [ ] Textarea clears after successful send

**4. Message Receiving (WebSocket) (5 tests)**
- [ ] Message received via WebSocket appears in list
- [ ] Auto-scroll to bottom on new message (when at bottom)
- [ ] No auto-scroll if user scrolled up
- [ ] Auto-scroll re-enables when user scrolls to bottom
- [ ] No duplicate messages (deduplication works)

**5. Read/Unread Tracking (7 tests)**
- [ ] Badge hidden when count = 0
- [ ] Badge shows count when window closed
- [ ] Badge shows "99+" when count >= 100
- [ ] Badge resets to 0 when window opened
- [ ] Badge increments when viewing different channel
- [ ] Badge does NOT increment when viewing active channel
- [ ] lastReadAt persists in localStorage

**6. Error Handling (6 tests)**
- [ ] WebSocket disconnection shows yellow banner (new in 11-01)
- [ ] Banner disappears on reconnection
- [ ] Send failure shows red error with retry button (new in 11-01)
- [ ] Retry button works and clears error
- [ ] fetchChatHistory failure shows error message (new in 11-01)
- [ ] Send button disabled when disconnected

**7. Performance (4 tests)**
- [ ] 50+ messages render without lag
- [ ] Auto-scroll smooth (no jank)
- [ ] Typing in textarea responsive (no input delay)
- [ ] Window open/close fast (<100ms perceived)

**8. Accessibility (5 tests)**
- [ ] Tab order logical (button → textarea → send → close)
- [ ] ARIA attributes present (verify in DevTools)
- [ ] Escape key closes window (new in 11-01)
- [ ] Textarea auto-focuses on open (new in 11-01)
- [ ] Screen reader announces validation messages (if VoiceOver available)

**9. Edge Cases (4 tests)**
- [ ] Send while disconnected → button disabled, shows warning
- [ ] Receive 10 messages rapidly → all appear, badge updates
- [ ] Open/close 10x rapidly → no errors
- [ ] Page reload → lastReadAt persists, messages cleared (expected)

<task type="checkpoint:human-verify" gate="blocking">
  <what-built>Complete chat feature with error handling, accessibility, and polish from Plan 11-01</what-built>
  <how-to-verify>
**Prerequisites:**
1. Ensure Rails backend is running: `./runweb` (port 3000)
2. Ensure jam-ui is running: `cd jam-ui && npm run start` (port 4000)
3. Have 2 browser tabs ready (for multi-user testing if needed)

**Automated Tests:**
```bash
cd jam-ui
npm test -- test/chat/*.spec.ts
```
✅ All tests should pass (29+ tests total)

**Manual UAT - Follow the 50+ test checklist from Task 1:**

Go through each category systematically:
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) - *Focus on new features from 11-01*
7. ✅ Performance (4 tests)
8. ✅ Accessibility (5 tests) - *Focus on new features from 11-01*
9. ✅ Edge Cases (4 tests)

**For each test:**
- Mark ✅ if passing
- Mark ❌ with description if failing
- Severity: P0 (critical), P1 (high), P2 (medium), P3 (low)

**Focus areas from Plan 11-01:**
- Error displays (red/yellow banners, retry button)
- Keyboard navigation (Escape key, Tab order)
- Focus management (textarea auto-focus)
- ARIA attributes (check with DevTools Accessibility inspector)

**Regression checks:**
- Backing Track player still works
- JamTrack player still works
- Other session features unaffected

**Report format:**
