useWaveform.ts:
- Remove requestAnimationFrame polling loop that was re-running after every
re-initialization and leaking across renders when cleanup didn't fire
- Remove local useState for isPlaying/currentTime/duration; these now come
directly from usePlayerStore selectors — WaveSurfer event handlers in
AudioService already write to the store, so no intermediate sync needed
- The useEffect is now a clean async init only; no cleanup needed (AudioService
persists intentionally across page navigations)
tests/:
- Delete 3 obsolete test files that tested removed APIs (logging system,
setupAudioContext, ensureAudioContext, initializeAudioContext)
- Add tests/audioService.test.ts: 25 tests covering initialize(), play(),
pause(), seekTo(), cleanup(), and all WaveSurfer event→store mappings
