Accumulated Context

Decisions

Decisions are logged in PROJECT.md Key Decisions table.

Date	Phase	Decision	Rationale
2026-02-08	18-01	Use privacy select as modal indicator	Avoids toast notification collision
2026-02-08	18-01	page.route() for API interception	Simpler than APIInterceptor for single-request
2026-02-08	19-01	vuStates unbounded growth is HIGH priority	Primary leak source - accumulates with track changes
2026-02-08	19-01	Chat messages unbounded is HIGH priority	Secondary leak source - grows with chat activity
2026-02-08	19-01	Session screen base has proper cleanup	Not primary leak source - hooks have cleanup functions
2026-02-08	20-01	Use Set comparison for mixer removal detection	Efficient Set.has() lookup for removed mixers
2026-02-08	20-01	Track previous mixer IDs with ref	Avoids re-render triggers from tracking state
2026-02-08	20-01	Guard cleanup with isReadyRedux check	Prevents false positives during initial mount
2026-02-08	21-01	MAX_MESSAGES = 500 per channel	Sufficient for long sessions while bounding memory
2026-02-08	21-01	Preserve lastReadAt across sessions	Keeps unread badge accurate for UX continuity
2026-02-08	21-01	Clear chat before session state	Ensures proper cleanup order
2026-02-08	22-01	useRef for callback cleanup stability	Avoids stale closure issues on unmount
2026-02-10	23-01	UAT checklist for manual memory profiling	Cannot fully automate Chrome DevTools verification
2026-02-10	23-01	15+ minute stability as primary metric	Reflects real-world usage patterns

Deferred Issues

1. End-of-track restart requires double-click (Minor) - From v1.0
2. Loop functionality not working (Medium) - From v1.0
3. Volume control not working in popup mode (Medium) - From v1.0
4. WebSocket chat messages only broadcast to musicians (Medium) - From v1.2
5. mp3 backend support (Medium) - Frontend allows, backend whitelist doesn't support
6. Pre-existing test failures in JKChatMessageList.test.js (Low) - Missing activeSession state
