111 of 122 top-level src/utils/ files move into 16 topic folders (audio,
cache, cover, share, server, playback, playlist, deviceSync, waveform,
mix, format, export, changelog, ui, perf, componentHelpers). True
singletons with no cluster stay at the utils/ root.
Pure file-move: a path-aware codemod rewrote 539 relative-import
specifiers across 275 files; no logic touched. The hot-path coverage
gate list (.github/frontend-hot-path-files.txt) is updated to the new
paths for the 11 gated utils files — a mechanical consequence of the
move, not a CI change. tsc is green.
Extract the canvas frequency-response math, the custom vertical fader, the
AutoEQ parser, and the AutoEQ search panel out of Equalizer.tsx:
- utils/eqCurve.ts biquadPeakResponse + drawCurve
- utils/autoEqParse.ts AutoEq types + parseFixedBandEqString
- components/equalizer/VerticalFader.tsx
- hooks/useAutoEq.ts AutoEQ search/apply state
- components/equalizer/AutoEqSection.tsx
Pure code-move, no behaviour change. Both call sites (AudioTab, PlayerBar)
default-import Equalizer unchanged.
