Three domain-eng modules peel ~316 LOC of fetch/mapping out of `api/subsonic.ts`: - `subsonicLibrary.ts` — browse + random + per-song fetch (`getMusicDirectory`, `getMusicIndexes`, `getMusicFolders`, `getRandomAlbums`, `getAlbumList`, `getRandomSongs`, `getRandomSongsFiltered`, `getSong`, `getAlbum`, `filterSongsToActiveLibrary`, `similarSongsRequestCount`, plus the private `albumIdsInActiveLibraryScope` cache). - `subsonicArtists.ts` — artist endpoints (`getArtists`, `getArtist`, `getArtistInfo`, `getTopSongs`, `getSimilarSongs2`, `getSimilarSongs`). Uses Library's `filterSongsToActiveLibrary` and `similarSongsRequestCount` for the per-library scoping fallback. - `subsonicRatings.ts` — `parseSubsonicEntityStarRating` parser plus `prefetchArtistUserRatings` and `prefetchAlbumUserRatings` workers with the shared 7-min cache. Calls back into Library/Artists for the per-id fetch. 51 external call sites migrated to direct imports. No re-export shims in `subsonic.ts`. Statistics endpoints still in `subsonic.ts` keep their `RATING_CACHE_TTL` constant locally (same 7-min window). subsonic.ts: 1078 → 762 LOC (−316).
