Post-restart completion recovery joined directory/filename, losing the base-directory component the Task constructor strips on custom roots. An unresolvable queue head (offline server) broke out of the drain loop, stalling every other queued download; the drain now excludes it and continues. The download tree also read all-cancelled or partial containers as completed.
The queued-download resume was a one-shot on the first online client, so a persisted row skipped because its server was offline stayed queued until restart. The resume now re-fires whenever a server comes online that the last resume did not cover (including reconnects), and a resume landing mid-drain re-drives the pass instead of being swallowed by the processing guard.
Deleting an episode fanned out one network playback-extras request per sibling row; the reference scan is now cache-only, retaining thumbnails when a sibling cannot be resolved. Season/show deletion removes rows sequentially, so that conservative retention would have counted siblings queued in the same batch - a sibling, or the container row whose extras cache is always a miss, made every episode retain its thumbnails and orphaned the files once the batch's rows were gone. The fan-out threads the batch's rating keys through so rows scheduled to disappear neither retain thumbnails nor contribute in-use paths; genuinely surviving rows still trigger retention.
connections.isDefault was maintained by three write paths (upsert preservation, remove-promotion, setDefault) that no production code ever read back; api_cache.cached_at was documented 'optional future use' and written on every cache store. Both columns are dropped in a v21 migration with row-preservation coverage; the dead write machinery, recordAuthSuccess, updateSyncRuleLastExecuted, getDownloadOwnerCount, and OfflineActionType.fromId (rejection semantics live in the sync service's explicit switch) go with them.
Recovery-image compatibility: committed tvOS snapshots written by older builds still carry isDefault in connections rows, and the restore decoder deliberately rejects rows that do not round-trip exactly. A retired-columns allowlist now strips such keys before the strict check, so pre-retirement images stay restorable — the legacy-plaintext restore test caught this and now pins it. _bindServerStatusListener in main.dart also loses its unused provider param and resolver indirection.
Consolidates duplicated logic behind shared implementations — paginated
grid tabs, focus chrome, cached remote stores, sheet selection columns,
the server artifact store and a test fixture layer — and removes code
that had become unreachable. Net reduction of about 5,500 lines with no
behaviour change.
Where a fix had landed separately in code that moved into a shared
helper, the fix was re-applied inside the helper rather than left behind
in the copy that went away.
Introduces shared seams for paginated views, D-pad reorder, media control
routing, async singletons and the device method channel, then points the
open-coded copies at them.
Also removes unused models and duplicated provider/server plumbing, folds
the twice-implemented artifact store in the server, and factors the
repeated Flutter toolchain prologue in CI into a composite action.
Album/artist downloads expand to tracks with pinned parent metadata,
aggregate progress, container deletes with reference-counted album
covers, and a Music tab on the downloads screen with fully offline
album playback. Home rows include music libraries (fixes plex hub
items being filtered to video types) and audio playlists join
download/sync rules.
