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.
