Two small file-private helpers move into dedicated modules under src/store/: - `waveformRefreshGen.ts` — the per-track generation counter that guards against applying a stale waveform read after the cache was invalidated. Exposes `bumpWaveformRefreshGen` (existing) + `getWaveformRefreshGen` (new accessor that replaces the two direct reads at `refreshWaveformForTrack`). - `hotCacheTouch.ts` — `touchHotCacheOnPlayback` with its empty-id guards, called from every `audio_play` entry point. Both file-private; no caller-side changes outside playerStore's own imports. 8 focused tests pin the generation-increment + isolation contract and the touch helper's empty-id guards. playerStore 3302 → 3291 LOC.

/**
|
|
* Last-write-wins generation counter per track. Avoids applying a stale
|
|
* empty waveform read when `analysis:waveform-updated` bumps the gen after
|
|
* SQLite commit while an older `analysis_get_waveform_for_track` is still
|
|
* in flight. Gen is bumped only on explicit invalidation (waveform-updated,
|
|
* analysis storage), not on every `refreshWaveformForTrack` call —
|
|
* otherwise bursts (Lucky Mix, queue) cancel each other.
|
|
*
|
|
* Typical usage:
|
|
*
|
|
* const gen = getWaveformRefreshGen(trackId);
|
|
* const row = await invoke('analysis_get_waveform_for_track', { trackId });
|
|
* if (getWaveformRefreshGen(trackId) !== gen) return; // stale result
