Final slice of the per-item rendering pass. Wraps every tile widget
in an AnimatedSwitcher between the skeleton placeholder and the real
card. 220ms cross-fade with easeOut: tiles "settle into place"
rather than hard-cutting from shimmer to content. Since each tile
fades independently as its data lands — and the HydrationQueue's
concurrency cap drains in a natural cascade — the overall feel is
the staged "page builds piece by piece" effect we wanted, with no
per-tile position math required.
Bumps CachedNetworkImage fadeInDuration from zero to 120ms (server_
image.dart, discover_screen.dart). Imperceptible on cache hits since
the image decodes synchronously; on cache misses the bytes fade in
smoothly instead of popping. Slice 1's "zero fade" call was right
about the 500ms default being a regression, but 120ms threads the
needle.
Playlist detail wraps its body in the same AnimatedSwitcher so the
cold-load skeleton page cross-fades into the real track list.
Tiles affected: home _AlbumTile / _ArtistTile / _TrackTile + liked
_LikedAlbumTile / _LikedArtistTile / _LikedTrackRow + playlist
_SkeletonBody / _Body. All keyed via ValueKey so AnimatedSwitcher
detects the transition.
End of the per-item pass. Net behavior: cold visits paint shaped
pages instantly with skeletons, content cascades in as hydration
lands; warm visits paint fully from drift in the first frame.
End-to-end pilot of the per-item architecture. Home now reads from
the new homeIndexProvider (drift-first over CachedHomeIndex with
/api/home/index discovery + SWR), then each tile is a small
ConsumerWidget watching its own albumTileProvider/artistTileProvider/
trackTileProvider. Tiles render a matched-dimension skeleton while
their entity is still hydrating, and swap in the real card once
drift emits the populated row.
Track hydration is wired up — /api/tracks/:id already existed so
the queue's case 'track' just calls api.getTrack(id) and persists.
The visible behavior:
* Cold visit: small /api/home/index round-trip (IDs only, ~10×
smaller than /api/home), then sections appear shaped with
skeleton tiles; each tile materializes as the hydration queue
drains. No more "30s blank → everything pops in at once."
* Warm visit: drift index emits instantly, drift entity rows emit
instantly, no network. Page paints fully in the first frame.
* Mid-state: scrolling through a partially-hydrated section sees
real cards next to skeleton cards. Layout doesn't shift because
skeletons match real-card dimensions exactly.
CachedHomeSnapshot (and the legacy homeProvider) stay in place but
unconsumed by Flutter — left in for now so revert is cheap if the
new path needs reworking. Cleanup follow-up in a later slice.
Old /api/home endpoint untouched, so the web client keeps working
unchanged.
Server has been generating system_variant='discover' playlists since
M6a (internal/playlists/system.go and POST
/api/playlists/system/discover/refresh) but neither client surfaced
it. The Flutter home filtered system playlists by exact match on
'for_you' and 'songs_like_artist', dropping Discover. The web home
did the same. Tiles were generated server-side and silently
discarded by both clients.
Add a Discover slot to the playlists row in both:
- Flutter: 5-slot row now (For You, Discover, 3× Songs-like) with
matching placeholder state machine.
- Web: same shape, same placeholderVariant() call.
When the engine has built it, the real playlist tile renders;
otherwise a placeholder with the same building/pending/failed
status semantics as the other system tiles.
Three changes addressing the cold-start spinner + stale-on-revisit pain.
A. SWR on remaining cacheFirst providers
- artistProvider, artistAlbumsProvider, artistTracksProvider all gain
alwaysRefresh: true. Cache hit still renders instantly; one
background refresh per subscription keeps the row from going stale
forever.
- albumProvider (inline async*) and playlistDetailProvider (inline
async*) now keep a `revalidated` flag and kick a one-shot
background fetch on the first complete cache hit. Same effect as
cacheFirst's alwaysRefresh, just inline.
- Three providers gained the connectivity timeout that
album/artist/playlist already had.
B. Navigation hydration
- AlbumDetailScreen accepts `AlbumRef? seed`; ArtistDetailScreen
accepts `ArtistRef? seed`. When the live provider is still loading,
the seed populates cover/title/artist immediately so the page
isn't blank.
- Routing wires `extra: AlbumRef|ArtistRef` from go_router into
the seed parameter.
- Call sites updated: home (Recently added, Rediscover albums +
artists, Last played), artist detail album grid. Where a ref isn't
available (track actions sheet), the screen falls back to the
spinner — no regression.
C. Cold-start home skeleton
- Replace the full-screen CircularProgressIndicator on /home with a
layout-preserving skeleton: 5 section titles + 6 grey card-shaped
placeholders per row. The page feels populated immediately;
sections fill in independently as data arrives via the per-section
providers.
- Drops the unused DelayedLoading import.
Net effect: re-visits to detail screens render instantly (cache hit
+ silent refresh); first visit from a tile shows the seed header
immediately while tracks load; cold-start home shows a layout
skeleton instead of a 30s blank spinner.
Player bar: drop the volume slider — phone hardware controls volume.
Right cluster collapses to a single row of shuffle/repeat/queue.
Playlist card: GestureDetector defers to children by default, so taps
over the cover image area didn't always register. Add HitTestBehavior.opaque
so the whole card surface is tappable.
Update banner: was 3-4× the height of its text — IconButton's default
48dp tap target plus generous vertical padding dominated. Tighten
padding (8→4), shrink dismiss button to 32×32 with iconSize 16, slim
the action button to 28dp height with shrinkWrap tap target.
Home screen: ClampingScrollPhysics + 140dp bottom padding (already
applied in working tree) so scroll stops just above the mini-player.
Rewrites HomeScreen body to match the web home layout:
- Playlists row: For-You + 3 Songs-like + user playlists, with
PlaylistPlaceholderCard for empty slots driven by
systemPlaylistsStatusProvider
- Recently added: 50 albums in 2 rows of 25 sharing a scroll controller
- Rediscover: separate scrollers for albums (square) and artists
(circular) — same condition as web's two-scroller branch
- Most played: 75 tracks in 3 rows of 25 using new CompactTrackCard
- Last played: existing single row layout preserved
Empty states use design-system understated-mythic copy mirrored
verbatim from web. Loading state uses DelayedLoading so brief network
blips don't flash a spinner.
Closes the visible parity gap the operator hit when first opening the
Flutter app on a real device.

CI caught six issues against the new admin slice:
- AsyncValue<T> in this Riverpod 3.3.1 codebase exposes `.value`
(returns T?), not `.valueOrNull`. Switched the three admin readers
to match the established convention (player_bar, queue_screen,
now_playing_screen all use `.value`).
- home_screen.dart still has ctx.push calls in _albumsRow / _artistsRow
(carousel tap handlers) — restored the go_router import that
Task 2 over-eagerly removed.
- admin_user_edit_sheet.dart had a single-line `if (!await ...) return;`
that violated curly_braces_in_flow_control_structures. Wrapped in
braces.
- admin_quarantine_item.dart doc comment had `<top>` placeholders that
the analyzer flagged as unintended HTML. Rephrased without angle
brackets.

HomeScreen drops its 5 ad-hoc IconButton actions in favour of the shared
widget. LibraryScreen gains an actions row it didn't have before. Both
now consistent.

- models/playlist.dart (Playlist, PlaylistTrack, PlaylistDetail)
- api/endpoints/playlists.dart (list with kind=user|system|all, get detail)
- playlists/playlists_provider.dart (Riverpod family providers)
- playlists/playlists_list_screen.dart (with system-variant pill)
- playlists/playlist_detail_screen.dart (header + Play button + rows)
- /playlists + /playlists/:id routes wired
- Home AppBar: queue_music icon next to Search
Tracks with track_id=null render greyed-out + struck-through (matches
web's PlaylistTrackRow behavior). Tap a row plays from that position;
top-level Play button plays the full playable subset from track 0.
ApiClient.buildDio takes on401; the library's dioProvider wires it to
the auth controller's clearSession. The router redirect already handles
navigation away from authed screens once the session goes null.
HomeScreen surfaces the banner on connection_refused with Retry +
Change URL.
PlayerBar reads playbackState + mediaItem streams; hidden when no
queue. Home track-row tap, album play button, album track tap, artist
play button (shuffle) all route to playerActions.playTracks. Token +
baseUrl forwarded to the audio handler before each new queue.
Sections mirror the web home: Recently added · Rediscover (albums +
artists) · Most played · Last played artists. Tap routes pushed for
albums/artists; track-tap is wired in the player task. Pull-to-refresh
re-fetches /api/home.
