When profile guard fails (single-player profile detected):
- Show JavaScript alert explaining the issue
- Leave session cleanly via handleLeaveSession()
- Redirect to dashboard (/) instead of /client (404)
Alert message explains:
- Audio profile not suitable for multi-user sessions
- Need proper audio interface or create private session
TODO: Replace alert() with proper modal dialog component
that offers options like legacy app (create private session,
go to audio settings, cancel).
Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
Based on legacy app (web/app/assets/javascripts/wizard/gear_utils.js):
When canPlayWithOthers() fails (single-player profile detected):
- Legacy app shows dialog with options:
* Create private session → redirects to new session
* Go to audio settings → redirects to /account/audio
* Cancel → redirects to home
Current implementation (without dialog):
- Reject with error.controlled_location = false
- Redirect to home (/client) when profile check fails
- Prevents user from joining with inadequate audio profile
This matches legacy behavior of kicking user back to home, but
WITHOUT the dialog that explains why or offers alternatives.
TODO: Add JKSessionProfileDialog component with same options as
legacy 'single-player-profile-dialog' for better UX.

Two fixes for built-in audio profile issues:
1. Add JK.AlertCallback as alias for JK.HandleAlertCallback
- Native client calls default "JK.AlertCallback" before
SessionSetAlertCallback is registered
- Now both callback names point to same handler
- Added logging for alert code 40 (audio profile issues)
2. Provide proper error when guardAgainstSinglePlayerProfile fails
- Was calling reject() with no parameter (error = undefined)
- Now creates Error object with message and canPlayResult data
- Fixes "User profile is not appropriate for session: undefined"
These issues manifest with MacBook built-in mic/speakers when the
profile check fails canPlayWithOthers(), causing tracks to not
display because session guards don't pass.

Two bugs fixed:
1. Missing await for GetClientID() in leaveSessionRest
- jamClient.GetClientID() returns a Promise
- Was passed unresolved to deleteParticipant(), causing
DELETE /api/participants/[object Promise] 404 error
- Now properly awaited before use
2. Unsafe property access on error object
- error.controlled_location accessed without null check
- Changed to error?.controlled_location (optional chaining)
- Prevents "Cannot read properties of undefined" error
These issues manifested when using MacBook Pro built-in mic/speakers
instead of Scarlet audio interface, likely due to different
initialization timing or missing audio profile causing error paths.

The backend uses client_id to identify the sender and exclude them
from receiving their own message via WebSocket (avoiding duplication
with optimistic update).
Changes:
- rest.js: Add clientId parameter to sendChatMessage
- sessionChatSlice.js: Pass clientId to API call
- JKChatComposer.js: Get server.clientId from context and pass it
This fixes: Messages now broadcast to OTHER users in session, not
just the sender. The sender sees optimistic update immediately, other
users receive via WebSocket.

The WebSocket onmessage handler passes (message, payload) to callbacks,
where payload contains the actual message data. Updated handleChatMessage
to use the second parameter (payload) instead of first (message).
This fixes: Multi-user chat messages now properly received and displayed
Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
Enables real-time message delivery between users in the same session:
- Import addMessageFromWebSocket action from sessionChatSlice
- Create handleChatMessage callback to transform Protocol Buffer format
to Redux format (msg_id → id, sender_id → senderId, etc.)
- Register CHAT_MESSAGE (237) callback when joining session
- Messages now dispatched to Redux when received via WebSocket
This fixes:
- Multi-user message exchange (messages now appear for remote users)
- Badge updates (unread count increments when messages arrive)
Protocol Buffer format (ChatMessage):
- sender_name, sender_id, msg, msg_id, created_at
Redux format:
- id, senderId, senderName, message, createdAt, channel, sessionId
Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
- Updated sendMessage.fulfilled to extract user.name from nested user object
- Updated fetchChatHistory.fulfilled to transform API format to internal format
- API response: { user: { name: "..." }, user_id: "..." }
- Internal format: { senderName: "...", senderId: "..." }
- WebSocket messages already use user_name (unchanged)
Fixes 'Unknown' sender name for messages from API (send + fetch).
- Changed create action to render show.rabl view instead of raw model
- Response now includes nested user object with name field
- Matches format returned by GET /api/chat (index action)
- Fixes 'Unknown' sender name issue for sent messages
Follows lobby chat pattern for consistent API response format.
Tasks completed: 3/3
- Comprehensive error handling and status display
- Accessibility and keyboard navigation
- Polish and edge case handling
SUMMARY: .planning/phases/11-chat-finalization/11-01-SUMMARY.md
Polish edge case handling and add missing PropTypes for textarea ref.
- JKChatComposer: Add PropTypes for textareaRef prop, add defaultProps
- JKChatEmptyState: Update message to match plan spec ("Start the conversation!")
- Verified edge cases: clearSendError works with retry, rapid actions handled, empty states work
- All edge cases from plan verified: disconnection, long messages, rapid toggling, multiple unread
Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
Add persistent error display with retry button for send failures, WebSocket disconnection banner, and loading/error states for fetch operations.
- Add clearSendError action to sessionChatSlice for retry functionality
- JKChatComposer: Add retry button for sendError, improve error styling (red background)
- JKSessionChatWindow: Add disconnection banner (yellow) when !isConnected
- JKChatMessageList: Add loading spinner during fetch, error display for failed fetch
- Color coding: red for critical errors, yellow for warnings

Add comprehensive Playwright integration tests for chat unread badge:
- Badge visibility based on count (hidden at 0, visible with count)
- Badge text formatting (1-99, "99+" for 100+)
- Badge reset when window opened
- Badge increment logic (closed window vs different channel)
- Multiple message handling
- Badge state after page reload
Tests validate Redux state, localStorage persistence, and UI rendering.

- Test badge shows correct count (1-99)
- Test badge shows "99+" for counts >= 100
- Test button opens chat window
- Test duplicate window prevention
- Test badge resets when window opens
- 7 comprehensive test cases
- Added JKSessionChatButton import
- Replaced placeholder Chat button with new component
- Passes sessionId prop from Redux state
- Button positioned after Open menu, before Attach button
- Displays chat icon from assets
- Badge shows unread count (1-99) or "99+" for 100+
- Badge hidden when count = 0
- Reduced opacity when window already open
- Click handler opens chat window and sets active channel
- useCallback for handleClick optimization
Replace placeholder content with JKChatMessageList component:
- Import JKChatMessageList
- Remove placeholder div with text
- JKChatMessageList handles its own styling (flex: 1, padding, scroll)
- Update component documentation
Chat window now displays:
- Header with channel name and close button (fixed top)

- Loading spinner when fetching history
- Empty state when no messages
- Individual messages with avatars and timestamps
Layout follows flexbox pattern with header fixed and message list
filling remaining space with independent scrolling.
Ready for Plan 8.3 (Chat Button & Unread Badge).
Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
GREEN phase: Create message list component with:
- Redux integration (activeChannel, messages, fetchStatus selectors)
- Auto-scroll logic with scroll state management
- Scroll to bottom on mount and new messages
- Disable auto-scroll when user scrolls up
- Re-enable auto-scroll when user scrolls to bottom (50px threshold)
- 300ms debounce for scroll detection
- Loading state (JKChatLoadingSpinner)
- Empty state (JKChatEmptyState)
- Message rendering (JKChatMessage components)
Auto-scroll behavior:
- isUserScrolling state tracks manual scrolling
- scrollToBottom helper with smooth scrolling
- isAtBottom detects bottom position (50px threshold)
- handleScroll debounces scroll events (300ms)
- Cleanup timeout on unmount prevents memory leaks
Mock Element.prototype.scrollTo in tests (not available in JSDOM).
All 3 tests passing:
- Empty state display
- Loading spinner display
- Message rendering
Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
RED phase: Create test file with 3 test cases:
- Shows empty state when no messages
- Shows loading spinner when fetching
- Renders messages when available
Install @testing-library/react@12 and @testing-library/jest-dom@5
(compatible with React 16).
Create setupTests.js for jest-dom matchers.
Tests fail as expected (component not implemented yet).

Create two stateless components for chat UI states:
1. JKChatLoadingSpinner:
- Displays spinner from reactstrap
- Shows "Loading messages..." text
- Used when fetchStatus is 'loading'
2. JKChatEmptyState:
- Shows chat icon and encouraging message
- Used when message list is empty
- Centered layout with friendly copy
Both components are simple, stateless, and require no props.
Inline styles used for MVP (SCSS styling deferred to Plan 8.3).
