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.
Three action-factories peel ~25 setters out of the authStore body,
following the playerStore action-factory pattern from Phase E:
- `createServerProfileActions` — `addServer`, `updateServer`,
`removeServer` (the non-trivial one — drops every per-server map
entry for the removed id), `setServers`, `setActiveServer`,
`setLoggedIn`, `setConnecting`, `setConnectionError`, `logout`.
- `createAuthLastfmActions` — credentials + session connect/disconnect
+ error flag + master scrobbling toggle. Network calls (love /
scrobble) stay in the playerStore-side `lastfmActions.ts`.
- `createAudioSettingsActions` — replay-gain / normalization /
loudness mode toggles (each calls `usePlayerStore.getState()
.updateReplayGainForCurrentTrack()` so a running track catches up),
plus crossfade / gapless / hi-res / audio-output (no engine
callback needed).
Pure code-move; no behaviour change. authStore.ts: 518 → 428 LOC (−90).
