Seven domain-eng splits peel ~200 LOC of read endpoints out of
`api/subsonic.ts`:
- `subsonicStreamUrl.ts` — `buildStreamUrl`, `coverArtCacheKey`,
`buildCoverArtUrl`, `buildDownloadUrl` (token-signed URL builders
for the four /rest endpoints we hand to the browser).
- `subsonicStarRating.ts` — `getStarred`, `star`, `unstar`,
`setRating`, `probeEntityRatingSupport`. `setRating` still triggers
the lazy `navidromeBrowse` cache invalidation; the same-folder
lazy import path is preserved.
- `subsonicSearch.ts` — `search`, `searchSongsPaged`.
- `subsonicScrobble.ts` — `scrobbleSong`, `reportNowPlaying`,
`getNowPlaying`.
- `subsonicAlbumInfo.ts` — `getAlbumInfo2`.
- `subsonicLyrics.ts` — `getLyricsBySongId`.
- `subsonicGenres.ts` — `getGenres`, `getAlbumsByGenre`.
63 external call sites migrated to direct imports. Four `vi.mock`
targets in the store-level tests pointed at `../api/subsonic` and
were updated to the new module paths.
Pure code-move. subsonic.ts: 762 → 561 LOC (−201).
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.
`promoteCompletedStreamToHotCache` — wraps the `promote_stream_cache_to_hot_cache`
Rust IPC, forwards the resolved path + size into `useHotCacheStore` as a
`'stream-promote'` entry — moves into `src/store/promoteStreamCache.ts`.
File-private with four call sites; no caller-side changes outside
playerStore's own import.
9 focused tests pin the payload shape (incl. the `'mp3'` suffix fallback
and the null customDir pass-through), the success path that records the
entry, the early-returns for null / empty path, the `size || 0` fallback,
and the silent error swallow.
playerStore 3207 → 3189 LOC.
