Trakt was the one service outside the tracker abstraction. TraktScrobbleService
re-implemented the whole playback lifecycle beside TrackerCoordinator, and
TraktSyncService pushed watched state from its own WatchStateNotifier
subscription, so the player called two objects at every lifecycle point and one
watch could be written twice. TraktTracker now implements RealtimeScrobbleTracker
like Simkl; the duplicated player call sites collapse to one each, and Trakt
shares the coordinator's ID resolver instead of re-fetching show ids every
episode.
Capabilities are split so a tracker declares what it is rather than being
special-cased: ScrobblePolicy carries each service's own resend/seek rules,
EpisodeHistoryTracker names the remote row a per-item history write targets, and
SeriesProgressTracker covers one-counter-per-series services. Writes from all
four trackers go through a shared TrackerWriteQueue, generalised from the
Trakt-only queue, with the legacy Trakt payload migrated on load. Trakt becomes
the fourth TrackersProvider slot and TraktAccountProvider is deleted, so one
object owns the active session per profile.
Two failure paths found while consolidating are fixed here too.
The queue's retries only ran on profile bind, connect and app foreground, so a
network blip mid-session left queued watches waiting for the next foreground.
OfflineModeProvider now notifies on connectivity changes, not just offline-state
or WiFi-flag changes, and main.dart flushes the queue when the network returns.
The queue also counted every failure toward the five attempts that permanently
drop an item, so a rate limit or a service having a bad hour could discard a
pending watch - the loss the queue exists to prevent. Only an answer about the
write itself now spends an attempt: 4xx counts, while rate limits, 5xx,
recoverable token-refresh failures and requests that never arrived do not. A
back-off answer also defers that service for the rest of the flush, so a queue
holding many rows does not fire all of them at a service that just asked for
quiet.
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.
- Merge SeerrMovieDetails/SeerrTvDetails into one SeerrDetails model and
route both detail endpoints through a single request helper.
- Replace the three parallel tracker session/store/rebind-generation
triples in TrackersProvider with a _TrackerSlot record plus one _rebind
path.
- Fold the three JellyfinSequentialLauncher entry points onto a shared
_launchLocalQueue helper that owns loading, abort, shuffle and publish;
each caller now supplies only its fetch.
Replace the per-tracker json_serializable session classes and account stores with a shared TrackerSession (service-aware persisted validation), a single TrackerAccountStore, a shared TrackerHttpClient, and an AnimeListTrackerBase mixin for MAL/AniList. Scope the per-service rebind guard so a disconnect can't abort a racing profile load. Add migration-safety, MAL refresh, episode-count cache, and content-type tests.
