Replaces the Library Liked-tab ComingSoon placeholder with a real
hydrated view of liked artists / albums / tracks, plus the
offline-first toggle-like write path.
New:
- cache/mutations/MutationQueue.kt — minimal write-side of the
offline mutation queue (Phase 8 v1 only enqueues; the
connectivity-aware drain lands with Phase 12.2 SyncController).
Defines MutationKind.LIKE_TOGGLE + LikeTogglePayload + an
enqueueLikeToggle helper.
- api/endpoints/LikesApi.kt — Retrofit (POST/DELETE
`api/likes/{kind}/{id}` + GET `/api/likes/ids`). Plural-segment
mapping ("artist" → "artists") lives in LikesRepository.
- models/wire/LikesWire.kt — @Serializable LikedIdsWire matching
`internal/api/likes.go likedIDsResponse`.
- likes/data/LikesRepository.kt — observe (hydrated artists /
albums / tracks via the existing CachedAlbumDao /
CachedArtistDao / CachedTrackDao) + observeIsLiked +
toggleLike + refreshIds. Local userId is hardcoded as "local"
behind LOCAL_USER_ID; TODO marker for the Phase-11 swap to
AuthStore.userId. Write path is optimistic Room mutation →
best-effort REST → enqueue-on-failure, per
`feedback_offline_first_for_server_writes`.
- likes/ui/LikedTab.kt — VM + UiState + composable. Three sections
(Artists horizontal row, Albums horizontal row, Tracks list) +
"No likes yet" empty state. Tile taps navigate to detail screens;
track-row taps are disabled until Phase 9 wires history play-from
-here (placeholder so the row reads correctly without an
unfinished playback affordance).
Modified:
- cache/db/DatabaseModule.kt — @Provides for CachedLikeDao +
CachedMutationDao (DAOs existed but had no consumer until now).
- library/ui/LibraryScreen.kt — TAB_LIKED dispatch swaps from
ComingSoonTab to `LikedTab(navController)`.
Like buttons on detail screens come with the AlbumDetail / ArtistDetail
real-screen build, which is a separate later commit (they're still
ComingSoon stubs in MinstrelNavGraph).
