First slice of the authStore split. Pure code-move: no behaviour change.
- `authStoreTypes.ts` — `ServerProfile`, `AuthState`, plus all union
types (`SeekbarStyle`, `LoggingMode`, `NormalizationEngine`,
`DiscordCoverSource`, `LoudnessLufsPreset`, `LyricsSourceId`,
`LyricsSourceConfig`, `TrackPreviewLocation`, `TrackPreviewLocations`).
- `authStoreDefaults.ts` — `LOUDNESS_LUFS_PRESETS`,
`DEFAULT_LOUDNESS_PRE_ANALYSIS_ATTENUATION_DB`,
`TRACK_PREVIEW_LOCATIONS`, `DEFAULT_TRACK_PREVIEW_LOCATIONS`,
`DEFAULT_LYRICS_SOURCES`, `MIX_MIN_RATING_FILTER_MAX_STARS`,
`RANDOM_MIX_SIZE_OPTIONS`.
- `authStoreHelpers.ts` — `generateId`,
`sanitizeLoudnessLufsPreset`, `sanitizeLoudnessPreAnalysisFromStorage`,
`clampMixFilterMinStars`, `clampRandomMixSize`,
`clampSkipStarThreshold`, `skipStarCountStorageKey`,
`sanitizeSkipStarCounts`.
12 external call sites migrated to direct imports from the new
modules (no re-export shims left in authStore.ts — applies the
[feedback_prevent_god_modules] rule 5: avoid re-export debt).
authStore.ts: 889 → 518 LOC (−371).
Migrates ~74 call sites away from the playerStore re-export shims that
were kept during M0–E.41 to avoid touching 30+ imports per PR. Now
that the bigger refactor work is done, each helper goes back to its
real home:
- `initAudioListeners`, `installQueueUndoHotkey`, `flushPlayQueuePosition`
→ from their own store modules
- `getPlaybackProgressSnapshot`, `subscribePlaybackProgress`,
`PlaybackProgressSnapshot` → from `playbackProgress`
- `resolveReplayGainDb`, `shuffleArray`, `songToTrack`
→ from `utils/*`
- `_resetQueueUndoStacksForTest`, `consumePendingQueueListScrollTop`,
`registerQueueListScrollTopReader` → from `queueUndo`
- `PlayerState`, `Track` types → from `playerStoreTypes`
Drops the corresponding 13 re-export stubs from `playerStore.ts` and
the now-unused imports. Also drops dead section banners + per-wrapper
comments above one-line action delegates. Trims one stale "(separate
PR)" note in `transportLightActions.ts` since that follow-up landed
in E.39.
`playerStore.ts`: 180 → 112 LOC (−68). Down from Phase E's starting
3732 LOC.
`bootstrap.test.ts` mock target updated from `../store/playerStore`
to `../store/queueUndoHotkey` to keep the spy reachable after the
import change.
ContextMenu.test.tsx (11): renders nothing when closed, renders when
openContextMenu has run, closeContextMenu hides on next render. Song-type
shows Play Now / Play Next / Add to Queue; album-type shows Open Album
/ Play Next / Enqueue Album / Go to Artist; artist-type shows Start
Radio + share affordances; queue-item shows a Remove option the song
menu does not. Clicking an action calls the expected store method
(playNext, enqueue) and closes the menu. Escape on the menu closes it.
WaveformSeek.test.tsx (8): renders a canvas, cursor=default without
trackId (no-track-loaded affordance), cursor=pointer with a trackId.
Wheel guards: no seek without a trackId, no seek with duration=0. Wheel
commit wiring: 350 ms trailing debounce delays the seek call until
activity settles; rapid wheel events coalesce (fewer commits than
events). Mount + unmount completes without throwing.
Neither component joins the hot-path gate -- jsdom skips canvas drawing
and these files have large branch surfaces (ContextMenu has 13 menu
types, WaveformSeek has the animation loop + 11 seekbar styles) that
need behavioural smoke rather than line coverage. The tests cover the
contract the refactor must preserve; visual / interactive layers stay
on the manual smoke list.
Frontend suite: 363 -> 382 tests (+19).
