Three small tranches out of playerStore.ts: - src/utils/waveformParse.ts — waveformBlobLenOk + coerceWaveformBins (the parser that handles number[] / Uint8Array / ArrayLike payloads Rust serializes as). - src/utils/normalizationCompare.ts — normalizationAlmostEqual (tolerant null-aware dB comparison). - src/utils/seekErrors.ts — isRecoverableSeekError (retry classifier for the Rust seek pipeline). Each gets focused unit tests. All four were file-private, no external callers — pure code move. playerStore 3556 → 3516 LOC.
