Reusing a room means whoever enters first becomes the host, and moving the
session to someone else's library meant everyone leaving and re-entering in
the right order. The host can now promote any connected guest from the
participant list (Watch Together screen and the in-player session sheet),
with playback, control mode, and reconnect identities carried across.
The relay owns the swap: a new `transferHost` message validates the sender
is the live host and the target a connected modern-protocol guest, then
swaps `HostPeerID` and the reconnect verifiers (each peer keeps its own
token), persists the room, and broadcasts `hostChanged` to every peer.
Clients flip roles in place: the controller swaps its role engine while
keeping the session, message queue, and player attachment. A promoted guest
seeds the coordinator with the room's last known intent (a paused room
stays paused) and the known-peer roster so the fresh epoch re-gates
instead of solo-starting; a demoted host falls back to a reconciler with a
fresh clock sync and asks the new authority for state. Guests re-pin the
host identity, reset their sequence, and re-converge their clocks.
A rejected transfer (`not_host` / `peer_not_found`) surfaces as a toast
instead of tearing the session down. Pre-transfer app builds in the room
ignore `hostChanged` and stop following the room at the next transfer;
targets on an old sync protocol are not offered the action.
Participant.lastKnownPosition had zero reads or writes; SessionState.disconnected was never constructed, making isInSession's comparison tautological (now _session != null); the session indicator's onLeaveSession callback had no production passer; enterRoom's bool was awaited and discarded. Music engine: MusicPlayContext.id and sleepTimerEndsAt were write-only, and the coordinator constructor seam was never injected.
Guests joining an "Anyone" room saw "Host controls playback" and a
locked room until the host actually started something. Control mode
only travelled inside the host's PlaybackState broadcast, and every
broadcast path requires an active media epoch, so an idle lobby had no
carrier at all: guests sat on the joinAsGuest hostOnly default. The v1
protocol's sessionConfig message covered this; the v3 rewrite lost it.
Carry the mode on the host's join messages instead: the directed join
reply every participant already sends to a new peer, and the host's
reconnect re-announce. The field is optional on the wire ('cm'), so
older clients ignore it and rooms with older hosts degrade to the
previous behavior. Guests apply it only from the relay-derived host
peer ID, never from a join's own spoofable isHost flag.

A Portuguese user reported "Skip Intro" rendering in English on Android TV.
The locale files were not the problem - all 22 were structurally complete.
skip_marker_button.dart simply never imported strings.g.dart and assigned
'Skip Intro' / 'Skip Credits' / 'Next Episode' as plain literals. An audit of
lib/ found ~120 more sites in the same state, in four shapes that need
different fixes:
A literal in a file that never imported the i18n layer is the easy one -
skip_marker_button, performance_stats, track_label_builder and codec_utils all
render text with no `t` in the file at all. TrackLabelBuilder._compose now takes
a fallbackLabel builder instead of an English fallbackPrefix, so the caller
supplies t.audioTracks.track / t.videoControls.subtitleTrack and every unnamed
audio and subtitle row in the track menus is localized.
English reaching the user through an exception message is the widest one, and
it needs care: MediaServerException.message feeds both toString() - logs and
Sentry grouping - and verbatim UI display. Localizing it in place would make
bug-report logs follow the user's locale and split one Sentry issue into 22.
The MediaServer and Seerr families instead gain a nullable `display` alongside
the English `message`, and the six screens that print these errors read
`display ?? message`. PlaybackException keeps the opposite rule, because it
already carries a PlaybackFailureReason for logic and classifyPlaybackFailure
already builds it from t.messages: its stragglers are localized at the throw
site. That also removes the literal "Exception: " prefix Live TV users saw on
a tune failure, since PlaybackException.toString() returns the bare message.
Localized parts hand-concatenated with bare English are the shape no search for
Text('...') can find: '${t.common.pause} auto-scroll' on the home carousel,
'${day} at ${time}' on the Live TV schedule row, and an actor-screen count that
hand-rolled its plural as `n == 1 ? 'title' : 'titles'` - wrong for ru and pl
regardless of translation, now a real Slang plural.
Finally a literal assigned to provider state that a widget renders later:
DownloadProgress.errorMessage, and the four background_downloader notification
bodies, which sit inside a plugin config call where no widget-shaped search
reaches them.
Two things surfaced while converting. track_chapter_controls compared a track
label against 'Audio Track N' to swap in a localized version; once the builder
localized its own fallback that branch became unreachable, so it and the
orphaned _joinTrackLabel are gone. And discovery_view's PeerError fallback arm
looks like a leak but is not - its producers already localize, and a test says
so - so it stays as it is.
All 21 non-base locales are translated, including the 21 keys left empty by
earlier commits that were falling back to English. No locale has an empty value.
scripts/check_hardcoded_strings.py guards the three shapes a structural check
can see, and runs in ci_checks.sh after translation hygiene. Its first draft
passed its own tests while missing this very bug, because 'Skip Intro' is bound
to a local rather than handed to Text(); the name-bound rule that closes that
gap is restricted to phrase-shaped literals, or it cannot tell copy from the
identifiers this codebase binds constantly ('cast_row', 'auto', 'liveTv'). It
cannot see English inside a throw or assigned to a provider field - neither is
distinguishable from a log message without dataflow analysis - and the docstring
says so. label: and actionLabel: are deliberately unscanned: here they name a
diagnostic operation, and a check that is chronically red is a check that gets
switched off.
One commit rather than one per area: the keys, the 22 locale files and the
generated output are a single unit, and any partial split fails the repo's own
unused-key scan on the way through.

DD-3 gives video no exemption: a restricted vehicle must not play it at all. The
gate is read at the single point where media actually opens, so every path that
can start a picture - an explicit play, a gapless arm, a track or channel switch,
a frame-rate-match resume, a reload, and the queue navigation commands of the OS
media session - is covered by one check rather than by a guard at each call site.
A seek can also start playback with no play call, because mpv resumes when it
seeks off the end of a file, so a restricted seek is followed by a pause.
Watch Together needed the pause to be local. A vehicle stopping one peer is not a
room-wide intent: a guest's forced pause is swallowed by the attachment's ledger
rather than published, while a host's still pauses the room, because a host that
kept broadcasting a frozen anchor would stall or rewind every guest it was meant
to protect. The layer that owns a pause owns the resume for it, and one
acknowledgement is recorded per event, so a surplus cannot eat the user's next
real pause.
A room whose peers have all left is a code nobody is using, but the relay
kept it bound to the creator's reconnect capability and rejected every
other create with room_exists. The app compounded it: enterRoom only
promoted to host on room_not_found, so tapping a recent code landed the
user in the retained room as a guest of a host that was never coming
back, until the cleanup sweep finally dropped the room.
Create now replaces a room with no connected peers, and enterRoom hosts
the code when its probe join finds an empty room. An occupied room still
rejects create, including from its previous owner, and a host that is
merely disconnected still reclaims its peer ID through join with the
matching token.
Drops dead code across services, models, utils and widgets, including the
connection auth service, which had no implementer, and the Live TV DVR
provisioning models, which had no caller.
Tests that only covered deleted behaviour are removed or trimmed. No
behaviour change.
Guest switch dispatch pre-marked its dedup key and fired-and-forgot, so
any failure (fetch error, reload busy with an auto-advance, navigation
race with the host exiting) silently stranded the guest on the old media.
A CurrentPlaybackDispatcher now marks a key handled only after the sink
reports success against the committed identity, with a serialized
in-flight slot, timeout, and generation reset; the reconciler re-offers
unattached media on every host heartbeat, making the heartbeat the retry
channel. Fetches that outlive their dispatch are re-validated against the
current snapshot so a stale switch can't override the live one.
hostExitedPlayer now rides the controller's ordered message queue with
host authentication instead of racing state handling in the provider.
Replaces the imperative play/pause/seek/positionSync message soup with a
single host-authored PlaybackState (seq-ordered, anchor-extrapolated,
phase machine: loading/waitingForPeers/paused/playing) that doubles as
the heartbeat, plus guest status reports and host-applied control
requests. Fixes the guest seek-back loop while the host loads (readiness
was keyed on a pre-load !buffering snapshot and heartbeats broadcast
frozen positions), adds real group buffering coordination (stall grace,
scheduled simultaneous resumes, 15s safety timeout), rate-nudge drift
correction with passthrough-aware seek fallback, session-scoped message
handling (no lost messages during episode-switch detach gaps), and an
expected-state ledger replacing the racy remote-action flag.
