With the rail collapsed and Libraries expanded, DOWN from the header landed on a mounted but focus-excluded library node and was swallowed, trapping traversal; the focus order now matches the render exclusion and traversal scans past non-focusable candidates.
An action bar rebuilding on count change disposed every node, silently dropping focus and never notifying the TV host; bindings are now reused by stable identity (external focus node, else debugLabel) and the transition is reported. Positional reuse remains the only option for an unlabeled action, but it applies only while the action-list shape is provably unchanged - catalog detail enrichment inserting Request before a focused Trailer used to hand Trailer's focused binding, focus ring and next Select included, to Request. Those actions also carry stable debugLabels so their focus survives enrichment.
The text field consumed back on KeyDown outside the shared handler, letting one press act twice. It now marks the back coordinator like handleBackKeyAction does and keeps the down-only shape solely on TV, where the closing IME session swallows the matching KeyUp. Because onBack can move focus (empty search field -> sidebar), the orphaned KeyUp would otherwise drive app-level back on the new focus chain, so the field arms BackKeyUpSuppressor; the suppressor gained a hardware-level KeyUp observer that clears the armed state in a microtask after the press ends, removing the long-documented pinning hazard where an unconsumed KeyUp left it swallowing the next press.
The custom sidebar read as an ad-hoc widget: collapsed rows were the
expanded layout clipped to the strip, the libraries tree used a
staircase of indents and mixed row heights, and hover expansion pushed
the whole content area sideways.
Rebuild the rail on M3 Expressive geometry: collapsed destinations are
icon-only 56x32 pills centered in an 80px strip (48px icon-only on TV),
expanded rows are fixed-height destinations with a full-width stadium
indicator, and the two layouts crossfade/lerp during the width morph
instead of clipping. The libraries section is flattened into full-width
destination rows under a chevron header at standard destination
metrics, hover/touch expansion overlays content as a rounded, shadowed
panel over a dimmed scrim instead of pushing it, and rail width, item
morphs, content translate, and bleed all share one duration/curve.
Collapsing Libraries in the sidebar only lasted until the app closed. The
next launch always came back expanded, which buries the rest of the nav
menu for anyone running a lot of libraries.
The expansion flag was plain widget state on SideNavigationRailState. It
survived tab navigation only because MainScreen pins the rail with a
GlobalKey, and died on relaunch, profile switch or a layout change. It now
lives in the librariesSectionExpanded preference, so the rail reads and
writes the persisted value and follows a settings reset or import too.

The Explore tab appears for every Plex-backed profile because the Plex
Discover catalog source connects implicitly, with no way to opt out
short of a Jellyfin-only profile. Add a Show Explore Tab switch to
Appearance > Navigation that hides the tab in the bottom navigation and
side rail. UI-only: catalog sources stay connected so watchlist
surfaces keep working while the tab is hidden.

- 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.
Collapse duplicated setup across the suite into six shared helpers under
test/test_helpers/ and rewrite the 28 suites that were open-coding it:
http_fixtures.dart jsonResponse() for http.Response JSON stubs
library_tab_scaffold.dart pumps library tabs under their required ancestors
multi_server_fixtures.dart MultiServerProvider wiring for widget tests
playback_report_fakes.dart PlaybackReportCall + fake report sinks
profile_stack.dart production-shaped profile dependency graph
theme.dart testMonoTokens for fast-settling widget tests
