- Create __tests__ directory for client components
- Add test file with imports and mocks for react-i18next
- Create renderModal helper function with default props
- Add placeholder test verifying setup works
Plan 17-01: Create unit tests covering:
- UNIT-01: Modal renders with currentSession props
- UNIT-02: Save button calls onSave with correct payload
- UNIT-03: Loading state disables form interactions
Plan verification passed.
Connect the existing Resync button to the resyncAudio hook from useGearUtils.
Calls jamClient.SessionAudioResync() via native C++ bridge to perform audio
resync, with loading state and error handling via toast notifications.

- Create 16-02-SUMMARY.md documenting UAT completion and bug fixes
- Update ROADMAP.md to mark Phase 16 as complete (2/2 plans)
- Mark v1.2 Session Attachments milestone as shipped (2026-02-07)
UAT discovered and fixed 2 bugs:
1. Attachment message deduplication race condition
2. Unread count not persisting across page reloads
All 26 requirements for v1.2 Session Attachments validated.

Problem: After page reload, the unread badge on chat button disappeared
even though there were unread messages.
Root cause:
1. unreadCounts was reset to {} on page reload
2. fetchChatHistory was only called when chat window opened
3. By that time, openChatWindow already reset the count to 0
Fix:
1. Fetch chat history when session joins (not just when chat opens)
2. In fetchChatHistory.fulfilled, calculate unread count based on
lastReadAt timestamp from localStorage
3. Only calculate unread if chat window is NOT open for that channel
This ensures the badge shows correct unread count after page reload.

The previous fix only added deduplication by attachmentId in addMessageFromWebSocket
and fetchChatHistory.fulfilled, but missed the uploadAttachment.fulfilled handler.
Race condition: WebSocket message can arrive BEFORE the upload API returns.
When this happens:
1. WebSocket delivers message with id='456', attachmentId=123
2. addMessageFromWebSocket adds it to state
3. Upload API returns
4. uploadAttachment.fulfilled only checked for id='attachment-123' → not found
5. Duplicate message added
Fix: Also check by attachmentId in uploadAttachment.fulfilled handler.

The optimistic message uses 'attachment-{notation.id}' as ID while
REST API and WebSocket use the chat message ID. This caused duplicates
when fetchChatHistory ran after an optimistic upload.
Now deduplication checks both message ID and attachmentId for attachment
messages, preventing duplicates regardless of ID format.

Phase 15 verified and complete with bug fixes:
- WebSocket handler extracts attachment fields correctly
- Deduplication works for both WebSocket and REST API paths
- Integration tests created (test/attachments/real-time-sync.spec.ts)
- Human verification passed
Bug fixes applied during UAT:
- Optimistic update for uploader (sender excluded from WebSocket)
- fetchChatHistory dispatch on channel activation
- API field name (chats not messages)
- API parameter name (music_session not session_id)
- Infinite loop prevention in fetch
Known limitation documented:
- WebSocket only broadcasts to musicians (as_musician: true filter)
- Pre-existing backend behavior, not introduced by v1.2
Requirements satisfied: REQ-3.1*, REQ-3.2
* REQ-3.1 has known limitation for non-musician participants

Backend's check_session filter expects 'music_session' parameter:
@music_session = ActiveMusicSession.find(params[:music_session])
But we were sending 'session_id', causing ActiveMusicSession.find(nil)
to fail.

The useEffect condition allowed fetching when fetchStatus was 'failed',
causing infinite retry loops when the API returned an error.
Changed condition from:
fetchStatus !== 'loading' && fetchStatus !== 'succeeded'
To:
fetchStatus === 'idle'
This ensures we only fetch once per channel on initial load, and don't
retry automatically on failure.
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
The fetchChatHistory thunk needs sessionId to determine channel type:
- With sessionId: fetches 'session' channel messages
- Without sessionId: fetches 'global' channel messages
The useEffect was only passing `channel` (which is the sessionId for
session chats), but not the `sessionId` parameter. This caused the
API to fetch global chat instead of session chat, so session messages
disappeared after page reload.
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
The chat history API returns { chats: [...], next: ... } but the
fetchChatHistory.fulfilled handler was expecting { messages: [...] }.
This caused a TypeError when opening the chat window because
`messages` was undefined.
Fixed:
- sessionChatSlice.js: Extract `chats` from payload, default to []
- Updated all test payloads to use `chats` field name

Issues found during UAT:
1. Uploader doesn't see their own attachment message
2. Chat history doesn't load on page refresh/rejoin
Root causes:
1. Backend's server_publish_to_session excludes sender from WebSocket
broadcast (exclude_client_id: sender[:client_id])
2. fetchChatHistory was imported but never called in JKChatMessageList
Fixes:
- Add optimistic message in uploadAttachment.fulfilled for uploader
Since sender is excluded from WebSocket, we add the message locally
using the MusicNotation response + user info
- Add useEffect in JKChatMessageList to dispatch fetchChatHistory
when channel becomes active
Technical details:
- Pass userId/userName to uploadAttachment thunk for message construction
- Use 'attachment-{notation.id}' as message ID to avoid collision
- Fetch history when fetchStatus is not 'loading' or 'succeeded'
