New media added server-side was invisible while the app was open - the
client had no channel for library-change notifications, so the home
screen and library tabs sat stale until an app restart.
Each online server now runs a reconnecting websocket push channel
(Plex `/:/websockets/notifications`; Jellyfin/Emby `/socket` with the
dialect deltas, including Emby's capabilities registration), owned per
server by a LibraryEventService supervisor that follows server
online/offline/replaced-client transitions and app lifecycle. Channels
emit one coalesced LibraryChangeEvent per burst on a leading-edge
throttle modeled on Plex Web's repopulate pacing: the first settled
change surfaces immediately and a library scan's flood merges behind
it. Connection failure degrades silently to the stale-refresh paths -
bounded reconnect backoff, re-armed on every status sync.
Consumers pace their reaction through one shared RefreshPacer: burst
debounce, blocked retry while video playback or an active scroll owns
the surface, a cooldown bounding pass frequency during bulk imports,
and credit for committed pull passes so a push landing right after a
fresh load defers to the cooldown's trailing edge.
- Discover runs a debounced full pass and swaps the result in place;
the hero carousel resets only when a pass lands first content, so a
push never yanks a screen the user is reading. Pushed removals drop
from every visible list immediately via the deletion bus, scoped to
the emitting server.
- The visible library tab swaps its data in place: transaction tabs
reload without clearing, and the browse and paginated card grids
refetch their loaded span (Plex Web's repopulateRange) with the
scroll offset anchored on the first visible item and the span
clamped after alpha jumps. Hidden tabs - and tabs behind another
main tab - mark per-library staleness epochs instead and reload when
next shown; epochs are snapshotted at load start so a push racing an
in-flight fetch stays stale.
- The stale-resume and tab-shown paths refetch home hubs (previously
Continue Watching only), covering setups where the socket cannot
connect.

getServerBoundPlexClient/getClientForLibrary existed only for their own unit tests; MetadataEditAdapter.backend and Plex's unreachable prefKey fallback and music-kind branches had no production path (edit is double-gated on supportsKind); MainScreenFocusScope's focus aspect, isSidebarFocused, and focusContent were write-only; resolveActivePlexIdentity.preferredAccount was never passed; ProfileRegistry.get was unused outside tests — its removal exposed a stale test contract, now pinned correctly: list() deliberately never serves plex_home rows.
- PaginatedCardGridTabState: the collections and playlists tabs were 95%
identical; they now supply only pageSize/fetchPage/idOf instead of each
duplicating the grid, memo, inflation budget and focus wiring.
- EtagCachedRemoteStore: the anime-lists and fribb mapping stores now share
one download/cache/isolate-parse/conditional-GET lifecycle.
- FocusableTileStateMixin manages its own initState/didUpdateWidget/dispose
instead of requiring every caller to forward three lifecycle hooks.
Also drops unused ServerCapabilities entries and dead code in
focusable_list_tile and music/track_row.
Introduces shared seams for paginated views, D-pad reorder, media control
routing, async singletons and the device method channel, then points the
open-coded copies at them.
Also removes unused models and duplicated provider/server plumbing, folds
the twice-implemented artifact store in the server, and factors the
repeated Flutter toolchain prologue in CI into a composite action.

A query submitted from the companion remote now behaves like a submit
instead of focus-to-type: TvKeyboardController closes an already-open
OSK and lands focus on the input without reopening it, then the shared
handleSearchSubmit path runs the search and focuses the first result.
Also guard DebouncedMediaSearch against selection-only controller
notifications re-arming the debounce into a duplicate fetch.
