The single-failure flip-to-false produced two false-positive permanent
banner cases:
1. Startup race — AuthStore.baseUrl loads from Room asynchronously, so the
first runOnce() can fire against AuthStore.DEFAULT_BASE_URL
("http://localhost:8080") before the real server URL has hydrated. One
failure was enough to lock the banner on for the next 5 minutes.
2. Deployments whose reverse proxy routes only /api/* to the Go server —
/healthz never reaches the handler, so /healthz polls fail forever even
though every real /api/* call succeeds. User sees "Server unreachable"
permanently and OfflineGatedDataSource starts throwing OfflineException
on every audio cache miss, silently breaking playback of uncached
tracks.
Now we require 3 consecutive failures (~15 min at the 5-min poll cadence)
before flipping reachable=false, and any single success resets the
counter. Adds Timber.w/i at the flip transitions so operator logcat can
diagnose genuine outages.
MutationQueue now emits "Saved — will sync when online" on a SharedFlow
whenever a user-driven enqueue lands (like toggle, playlist append,
request create/cancel, quarantine flag/unflag). Background enqueues
(play-offline events, playback-error reports) do not emit — those fire
from non-foreground paths where a snackbar would be either dropped
(no shell mounted) or jarring (lock-screen toggle).
ShellScaffold subscribes via OfflineWriteHintViewModel and routes the
hint through its existing snackbar host. Replaces the prior silent-
queue UX where a tap on a like / playlist add looked successful but
the user couldn't tell whether the server had been hit or the call
was deferred for replay.
TrackRow now consumes the LocalServerHealth CompositionLocal (provided
once at MainActivity from ServerHealthController.state). When the server
is Offline or ServerDown and the track id isn't in LocalCachedTrackIds,
the row dims to 0.4 alpha and a tap fires a Toast instead of attempting
playback. Replaces the silent "tap-and-fail-to-OfflineException" UX with
explicit at-a-glance signaling of which rows in a long list will work.
Trailing slot (kebab / like / playlist-add) stays interactive so write
affordances can route through MutationQueue — Phase 5 gates those at
the action level.
When ServerHealthController reports Offline or ServerDown, SearchRepository
runs Room LIKE queries against cached_artists / cached_albums / cached_tracks
instead of hitting /api/search. The screen draws a one-line hint above the
results so the user can tell server matches from on-device-only matches.
Adds searchByName / searchByTitle DAO methods; LOCAL_SEARCH_LIMIT=20 matches
the server's default page size.
Phase 3 of #618. Wraps the OkHttpDataSource upstream of CacheDataSource with OfflineGatedDataSource. CacheDataSource only consults the upstream factory on a cache miss, so playback of cached audio is unaffected. Offline tap on a non-cached track now throws OfflineException immediately (subclass of IOException for ExoPlayer's PlaybackException to wrap) instead of waiting on a multi-second OkHttp timeout. AudioPrefetcher keeps its own ungated upstream -- writes fail silently when offline, no user-visible impact.
Closes Scribe #611. The 2026-06-04 logcat showed 33 consecutive AddURIToQueue failures clustered at ~10ms intervals once the burst hit offset 39 -- characteristic of Sonos's burst-add rate-limit. 50ms between successful adds adds ~5s to the 100-track background extension but eliminates the burst rejection. Next reproduction with the SOAP fault detail logging (audit commit c5b326c6) will confirm the fault code if any tracks still fail.
Closes Scribe #606. Two pieces: MediaMetadata gets durationMs (lock-screen scrubber gets a known total even when wrapped ExoPlayer is paused under UPnP); MinstrelForwardingPlayer keeps an externalListeners registry that mirrors super.addListener so we can directly invoke onIsPlayingChanged / onPlaybackStateChanged / onMediaItemTransition when remoteState mutates. Fires from pollOnce + play()/pause() onSuccess. dedup via lastNotified guards so we don't spam events at 1Hz when nothing changed.
TRUNCATE-everything ResetDB before every test forces a commit fsync; the CI DB is rebuilt each run so durability buys nothing. ALTER SYSTEM via docker exec (the services: block can't override the postgres command line). Non-fatal so a perms surprise degrades to slow, never red.
Per the playbook the operator shared from another project (~17x speedup observed there). Measure before/after in the next two CI runs.
Closes Scribe #614, #615, server half of #616 surfaced by the 2026-06-04 divergent-provider audit.
- streamURL helper now used everywhere /api/tracks/{id}/stream is built (was inline concat in playlists.go and cast_token.go); add streamURLWithExt for the .ext cast variant.
- audioContentType in media.go is the canonical file_format -> MIME lookup; mimeForFormat in cast_token.go is now a thin wrapper that overrides the unknown-format fallback to audio/mpeg (Sonos rejects octet-stream). Adds mpeg/vorbis/wave aliases. Subsonic's contentTypeForFormat stays frozen per docs.
- coverart.ResolveAlbumPath extracted; api and subsonic both delegate to it.
Part A: split loadQueueOnSonos into an initial phase (tracks[0..currentIndex]
only, then SetAV+Seek+Play) plus a background extendQueueOnSonos coroutine
that appends the remainder after activation. Reduces the UPnP activation
block from ~17s (100 tracks serial) to ~200ms (1 track at currentIndex=0).
Background extension cancels cleanly when activeUpnpHolder.active changes.
Part B: add PlayerUiState.isUpnpLoading (target set, active null). Projected
inline in onEvents so it stays consistent with the rest of the snapshot, plus
a separate combine(target, active) collector that updates uiState between
player-event fires. NowPlayingScreen.TransportRow and MiniPlayer.MiniRow
replace the play/pause icon with a CircularProgressIndicator while loading
and disable the button tap to prevent premature commands to the Sonos queue.
