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.
single tap stacks while the skip pill is visible, feedback shows before
the seek (instant on transcode restarts), fade-out hide timer is tracked so
a re-shown pill isn't killed mid-spree, and tap pairing uses the platform

The TV keyboard dialog froze the field's callbacks at open time, so the
search screen's done key fell through to unfocus() once results arrived.
Resolve callbacks against the latest field widget at invoke time, and
give the search screen a TV submit handler that focuses the first result
or flushes the pending debounce.
Adds context.withFreshWatchState/readFreshWatchState and sweeps the
remaining session-critical readers: context menu actions, folder tree
rows, discover hero, and TV spotlight minutes-left.
Delete the per-event list patching, parent-count adjustment, and the
screen-local progress overlay; rows and the hero resolve against
WatchStateStore at build. Also backfill parentId on playable-descendant
pages so hierarchy resolution covers season detail pages.
Cards consult the hierarchy-aware store so container marks flip episode
rows instantly and a stale per-episode patch can no longer shadow a newer
show/season mark; playback opens with the session-fresh resume offset.
Resolution now considers parentChain ancestors (newest event wins) and
watched patches set container leaf counts, so container marks reach
descendant cards and vice versa.
The side-nav host's onSystemBack called _handleMainBack on the system
route-pop path, jumping straight to the home tab and skipping the dpad
back chain (content -> top tabs -> sidebar). Restore the original inert
behavior: canPop:false blocks the route-pop and the key path owns the
chain; the host still closes an open sheet on back. Bottom-nav unchanged.
Both main_screen hosts (side-nav + bottom-nav) drop their PopScopes and
pass canPop:false + onSystemBack to OverlaySheetHost, so a system back
with a sheet open closes the sheet instead of running tab-nav/exit. Key
(dpad) back path unchanged; onSystemBack mirrors it for a pure popRoute.
hub_detail and media_detail (TV + non-TV) drop their hand-rolled PopScopes
and pass canPop/onSystemBack to OverlaySheetHost. Keeps appbar-focus-first
and Android-keyboard block behavior; fixes system-back-with-sheet-open
leaking to a screen pop. iOS swipe-back preserved.
watch_together, video_player, mobile_remote and live_tv_show_schedule now
pass canPop/onSystemBack to OverlaySheetHost instead of hand-rolling a
PopScope. Restores the iOS swipe-back on watch_together and centralizes
the sheet-close-on-back logic.
Adds nullable canPop + onSystemBack to OverlaySheetHost. When canPop is
set, the host installs its own PopScope that closes an open sheet on a
system/route back instead of popping the screen; null keeps today's
behavior. Lets screens drop their hand-rolled sheet-back PopScopes.
