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'

- Create test/attachments/real-time-sync.spec.ts
- Test WebSocket message receipt for attachments
- Test deduplication of duplicate messages
- Test REST API and WebSocket message deduplication
- Test attachment display in chat
- Uses Redux dispatch simulation approach for CI compatibility
- Transform nested music_notation object from REST API to flat attachment fields

WARNING 1: Plan 02 keeps autonomous: false with comment explaining
checkpoint is for download flow verification
WARNING 2: Plan 01 must_haves.truths now includes edge case validation

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.
