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.

Polling alone cannot distinguish Sonos auto-advancing via SetNextAVTransportURI
from URI changes we made ourselves via syncCurrentItemToRemote. This produced
two races: (1) activation race -- first poll returns stale URI from prior
session, second returns new URI, false-positive fires and double-advances the
cursor; (2) user-skip race -- skip's syncCurrentItemToRemote changes the URI,
next poll sees the change and fires again. Remove the detection block and
previousTrackUri capture from pollOnce entirely. pollLoop is now a pure
state-tracker (position + transport state) plus the one-shot initial pre-queue
gate. GENA event subscriptions to AVTransport LastChange are the correct fix;
deferred to its own slice (see parity-map).

Add optional onRawResponse callback to SoapClient; loggingSoapClient
factory emits the first 6 GetPositionInfo/GetTransportInfo bodies
(3 poll cycles) at WARN so release logs capture them. Wire into
transportFor so every AVTransportClient for a new UPnP session logs.
