Drift cache intentionally drops cover_url (server-derived). The
adapters comment says "REST cold-cache fallback briefly shows the real
values before drift takes over" — but once drift takes over, covers
are empty forever. Fix per source:
- Album cover: server constructs the URL deterministically as
/api/albums/<id>/cover (internal/api/convert.go:69). Mirror that
in CachedAlbumAdapter.toRef so AlbumRef.coverUrl is non-empty
whether the row came from a fresh fetch or a drift hit. Restores
cover art on the artist detail album grid (and any other surface
reading albums from drift).
- Artist cover: server picks a representative album and reuses its
cover (convert.go:98). Drift doesn't store the pointer, so derive
client-side via the artist's first loaded album. New _ArtistAvatar
prefers a non-empty server-emitted coverUrl and falls back to
/api/albums/<firstAlbumId>/cover, then slate while the album list
is still loading.
Album grid spacing was off because childAspectRatio: 0.8 inflated
each cell taller than the AlbumCard's actual ~160dp footprint,
leaving a visible gap below every card. Switch to mainAxisExtent: 168
with explicit 8dp main/cross spacing — cells now match the card and
sit on a clean grid.
