Phase 29 verified and complete:
- MixersContext.Provider value memoized with useMemo
- VuContext separated from MixerConfigContext (Phase 28)
- 6 context consumers wrapped with React.memo
- useMixerHelper.getMixer stabilized with useCallback
Requirements satisfied: CTX-01, CTX-02, CTX-03

Tasks completed: 4/4
- Task 1a: Stabilize useMixerHelper function references
- Task 1b: Memoize MixersContext provider value
- Task 2: Memoize VuContext and GlobalContext provider values
- Task 3: Wrap context consumers with React.memo
SUMMARY: .planning/phases/29-context-optimization/29-01-SUMMARY.md
Accomplishments:
- Memoized all 3 context providers (MixersContext, VuContext, GlobalContext)
- Stabilized getMixer and dependent function references
- Wrapped 6 consumer components with React.memo
- Eliminated cascading re-renders from context value changes
Requirements completed:
- CTX-00: useMixerHelper.getMixer wrapped with useCallback
- CTX-01: MixersContext.Provider value is memoized
- CTX-03: Context consumers only re-render when data changes
Performance impact:
- Volume slider changes no longer re-render VU meters
- VU updates no longer re-render volume sliders
- Context consumers only re-render when their specific data changes
Phase 28 verified and approved:
- VU data flows through external store (vuStore.js)
- VU components use refs for direct DOM updates
- React DevTools shows 0 re-renders from VU updates
- Session screen remains responsive
Requirements satisfied: VU-01, VU-02, VU-03

Tasks completed: 4/4
- Update useMixerStore to route VU data to external store
- Simplify useVuHelpers and VuContext
- Rewrite SessionTrackVU with direct DOM updates
- Human verification (approved)
Additional fix:
- getLevelSnapshot now checks pendingUpdates for immediate access
SUMMARY: .planning/phases/28-vu-meter-optimization/28-02-SUMMARY.md

Phases:
28. VU Meter Optimization
29. Context Optimization
30. Component Memoization
31. Selector Optimization

Tasks completed: 3/3
- INT-01: Settings button opens modal
- INT-02: Save settings makes PUT /sessions/{id} API call
- INT-03: Cancel closes modal without API call
SUMMARY: .planning/phases/18-integration-tests-playwright/18-01-SUMMARY.md
Plan 18-01: Create integration tests covering:
- INT-01: Settings button opens modal
- INT-02: Save makes PUT /sessions/{id} API call
- INT-03: Cancel closes modal without API call
Plan verification passed.
Tasks completed: 3/3
- Task 1: Create test file with setup and mocks
- Task 2: Write tests for all three requirements
- Task 3: Verify full test suite and clean up
SUMMARY: .planning/phases/17-unit-tests-jest/17-01-SUMMARY.md
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.
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
