Enable noUncheckedIndexedAccess and fix all 98 call sites it surfaced across 18
files. Every fix is behaviour-preserving — the flag flagged reads TypeScript
couldn't prove in-bounds, all of which were already guarded by a length/index check,
a findIndex result, or a non-empty invariant:
- read-once so a ternary's narrowing sticks (Feed overrides, linkify mention);
- non-null assertion AFTER an existing guard (PlayerModal/VideoEditor queue+cut-list
indexing, modules step, useUndoable stacks) with a comment stating the invariant;
- nullish fallback where undefined is a real possibility (GlassTuner slider ?? def,
ConfigPanel active group ?? [], descriptionLinks id ?? null);
- optional chaining where the entry genuinely can be absent (PlexBrowse IO entry);
- a non-empty tuple type for the RELATIVE_UNITS constant (encodes "always has [0]").
The single highest-leverage fix: PlayerModal's `active` became `queue?.[index] ??
video` (always Video), clearing 34 of the 45 errors in that file at once. Verified:
tsc/eslint/prettier clean, 56 vitest + 34 pytest + 17/17 e2e green (the e2e suite
exercises the feed/player/channel components touched here).
Prettier 3 (pinned), printWidth 100, double quotes — chosen to match the existing
hand-formatting and minimise reflow. This commit is ONLY the mechanical format pass
(`prettier --write`) plus the config/ignore/scripts, isolated so it never pollutes a
feature diff. Verified behaviour-neutral: typecheck, eslint (0 errors), and vitest
all green before and after. See .git-blame-ignore-revs — `git blame` skips this sha.
Review follow-up: the ordered MODULES array can't double as a compiler-
enforced exhaustive Page map, so document that adding a Page means adding it
here (an unregistered Page returns undefined from moduleDef/moduleLabelKey and
throws in NavSidebar). No behavior change. (Platform S6b.2)
Extend lib/modules.ts into an ordered ModuleDef registry (id/label/icon/
system/badge/gate) as the single source for the nav rail and the header
stepper. Absorb NavSidebar's per-page ICON map; derive moduleOrder /
moduleLabelKey / SYSTEM_PAGES from the one array. Render still on the App
ternary — this is the scaffold S6b.3 will drive from. (Platform S6b.1)
Replace the full-width top bar with a fixed floating header of glass pills: a
fixed-position ModuleName (accent dot + label + prev/next cyclic module stepper)
and a shared SearchBar. The header's left edge is anchored as if the nav rail
and filter sidebar were both open, so it never shifts on collapse or module
change; the right edge leaves a 10% margin.
- ModuleName label width is measured live from the reachable modules' titles in
the current language, recomputing on a language or account change.
- Module names come from a shared moduleLabelKey (the same short labels as the
nav rail); NavSidebar and the header now read from one source (lib/modules.ts).
- The arrows step cyclically through moduleOrder(me) — dynamic, no hard-coded
targets, wrapping at both ends.
- Search is hoisted into the SearchBar for feed (YouTube search), plex, channels
(including the Discovery tab) and playlists (new); Go button, Enter triggers it.
- The Playlists left rail now reaches the top; header clearance via --hdr-h.
