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).
Cluster of three small thematically-related cuts in one PR (per the new
'cluster, don't single-shot' convention):
- `src/store/seekTargetState.ts` — the seek-target guard (`seekTarget`,
`seekTargetSetAt`, `SEEK_TARGET_GUARD_TIMEOUT_MS`, set/clear/get
accessors) that suppresses stale Rust progress ticks until the
engine catches up to the requested position
- `src/store/togglePlayLock.ts` — the 300 ms double-click cooldown
behind a `tryAcquireTogglePlayLock()` helper that auto-releases on
a timer (collapses the three-line inline pattern in `togglePlay`)
- `src/store/loudnessReseed.ts` — the full `reseedLoudnessForTrackId`
pipeline (gen-bump → cache + backfill wipe → state reset → server
row delete → forced seed enqueue), pulled out of playerStore as a
single async helper
All three were file-private; no caller-side changes outside
playerStore's own imports. The progress handler's seek-guard branch is
now ~3 lines shorter and reads through accessors. `togglePlay` collapses
to one guard check.
24 tests across the three modules pin the API contracts.
playerStore 3189 → 3139 LOC.
