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
