UX-8 layerStack: add an integration test wired through the real useLayer
hook (popover document-listener + stamp) and a PlayerModal-shaped window
listener, driven by a real dispatched keydown. The popover close is wrapped
in flushSync so its layer is popped synchronously between the two listeners
-- the production mid-dispatch race -- making the escapeHandled stamp the
only thing that keeps the player from also closing. Mutation-checked:
removing the guard fails exactly this case.
SavedViews: cover feedCanSeedDefault's "yield to a bookmarked filter URL"
branch (a filter-bearing search string -> no seed) and the per-source
seededRef guard against the 60s refetch (a changed-list refetch re-runs the
seed effect; the guard blocks re-seed). The refetch test waits for the
changed list to reach the component so the effect has its chance to wrongly
re-fire. Both mutation-checked.
Frontend gate green: 464 vitest (+4). Backend untouched.
The S2 seed effect ran on the saved-views query's first resolve, but that
query is ungated and — since SavedViewsProvider mounts above <App>, which pins
the tab-account only after /api/me — resolves before the account is known on a
fresh tab. It then evaluated canSeedDefault() against a null account (which
reports 'stored, do not seed') and burned its one-shot guard, so the starred
default was never applied until a reload: exactly the fresh-tab miss S2 set out
to fix. Gate the effect on the reactive account id so it defers instead of
consuming the guard, and re-fires when the account pins. Covers feed + plex.
Adds a dom test for the defer-then-seed-on-pin path the old test masked by
pre-pinning the account.
The feed applied its starred default via a localStorage mirror
(LS.defaultViewFilters) written by SavedViewsProvider and read by
FeedFiltersProvider on load. That raced the login effect: on a genuinely
fresh browser (no LS.filters and no mirror yet) the feed could seed
DEFAULT_FILTERS and never re-apply the default until a reload. Plex had no
default-application at all.
Replace the mirror with a single path: SavedViewsProvider applies the
starred default via cfg.setFilters on the views query's FIRST resolve, but
only into a genuinely fresh module (no stored filters for the account, and
— feed only — no URL filter override). Applying persists it, so it happens
once and the last-view-wins path takes over, matching the documented
storage semantics. Because it runs off cfg.setFilters it delivers the Plex
port for free. Extract pickDefaultToSeed (pure, unit-tested) and cover the
first-resolve/stored/no-default cases for both modules in a provider test.
Removes the now-dead LS.defaultViewFilters key and its mirror read.
