The cross-item subtitle intent required declared languages on both sides,
and a null on either side counted as a contradiction. Any untagged track -
common when a title like "Swedish" is the only signal - declined on every
episode advance, fell to the server's per-item priority, and turned the
viewer's subtitles off (a 2.11.0 regression from the #1716/#1717 hard
gates).
A unique real title match now vouches for a row when language evidence is
missing on either side. Declared languages that disagree still decline no
matter what the title says, forced-class parity is untouched, codec and
external parity only break ties within the title-matched set, and a
residual tie declines rather than guesses, so the wrong-track class of
#1716 stays closed.
A decline is also no longer laundered into a viewer decision: the resolver
keeps the unserved preference on the selection, the open flow hands it to
the track manager instead of a navigation-priority off (late native tracks
may carry the container tags the server rows lack), the next episode
boundary re-carries it instead of hardening it into an explicit off, and
progress reports withhold the -1 subtitle index that would otherwise come
back as the item's server-side default forever.
A pick the screen could not map to a source row (no subtitle catalog, or
an identity-matcher miss) previously never reached the committed session
selection at all, so the next episode carried the stale off while the
picked track was visibly on screen. Such picks now commit the raw native
track without source ids and demote to a semantic intent at the boundary.

Plezy reported a completed playback twice: the /:/timeline heartbeats let
the server mark the item played on its own, and the in-player auto-scrobble
then sent an explicit /:/scrobble for the same watch. On PMS 1.30 that adds
a second Play History row; on 1.43 the row is suppressed but viewCount still
lands on 2 for one playback.
Measured against PMS 1.43 to find what the server acts on: a watched-threshold
crossing observed inside one session. Consecutive above-threshold reports mark
nothing, a resume point left by an earlier session does not arm a new one, and
a report at position zero is inert while one at a single second is enough. So
the explicit mark now goes out only for sessions that gave the server no
crossing to observe.
That decision cannot be made while the session is live. A session beginning
past the threshold has no crossing yet, but rewinding and playing forward
creates one, and the server records it — marking eagerly and then hitting that
path leaves viewCount at 2 again. The mark is therefore deferred to the
terminal stop, and rides its future so callers that await the stop before
tearing the player down do not drop it. Deferring also covers a crossing
coalesced away during startup and a seek back below the threshold before
stopping.
Crossing state is tracked from reports the backend actually received rather
than from PlaybackReportSession.report()'s bool, which resolves true for a
same-state snapshot dropped during startup.
The same-file sibling hook (#1500) still runs exactly once, on the transition
to a settled mark rather than at the local crossing, so sibling episodes are
never marked watched while the episode actually played is not.
Local watched state and Continue Watching removal still happen on the observed
crossing, so the only behaviour that moves is the redundant server call.

Deduplicates the hand-rolled coalescing/caching maps, the Plex client cast,
the missing-serverId event guard and the progress-failure backoff, and drops
the MusicPlaybackService availability gate, which could never fail in
production.
Report the paused timeline every tick (~10s, matching official clients)
instead of every ~60s, and ping the Plex transcoder keepalive endpoint
alongside it while transcoding — PMS reaps idle transcode sessions that
timeline reports alone historically have not kept alive. Prevents the
transcode-variant of the #1520 stream death; the reporter's direct-play
case is covered by EOF classification and reconnect.
