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.
Platform-prefixed handles (x/twitter/instagram/facebook/tiktok/youtube/twitch/threads/
telegram/soundcloud) now link to the platform's profile URL — only the @handle is
linked, the '<platform>:' label stays as text. A required colon/arrow separator + the
known-platform list keep false positives out; a bare @handle with no platform stays plain.
The description linkifier only caught http(s):// URLs; extend it to www.* hosts and
bare domain.tld/path URLs (both get an https:// href prefix), so links like
www.amelielens.com and facebook.com/amelielensmusic become clickable too. A required
path + letters-only TLD keep false positives (version numbers, file names) out; bare
@handles and #hashtags stay plain (the platform is ambiguous).
- linkify: bare http(s) URLs inside channel descriptions become clickable links
(new tab, rel=noopener noreferrer) — new lib/linkify.tsx, used in the shared
ChannelAboutContent so both the About overlay and the channel detail page get it
- Country flag: the flag EMOJI never renders on Windows/Chrome (showed the small-caps
'hu' fallback), so swap it for a real self-hosted SVG flag via the flag-icons package;
applies to the About overlay + the channel detail page
