Burns the first 14 of the 113 hook suppressions. Three verdicts, applied per site:
A useEffect that should not exist (6):
- Avatar remembered "the image failed" as a boolean an effect reset on src change. The
component is recycled across items in the virtualized feed, so after one avatar 429s the
next item's slot committed the fallback initial over a perfectly good image and only the
post-paint effect cleared it. The failure is now keyed BY URL; derived state cannot be stale.
- Combobox cleared the typed query from an effect on `open`. Moved into setOpenAnd, the single
funnel every close goes through. That also stops a spurious onQueryChange("") AT MOUNT, which
told a controlled caller its own initial query had been cleared before the user touched it.
- CommandPalette reset query + picked row from an effect. Closed now means UNMOUNTED, not
hidden, so a fresh open starts blank because mounting already means that -- and the ranking
memo over every channel, playlist and saved view stops running while the palette is shut.
- Pager's page box held a copy of the page that an effect re-synced; it now derives it and
keeps a draft only while being edited.
- App's ?link= / ?oauth= / ?admin= one-shots asserted "once per mount" with an empty dep list.
The ref guard the codebase already uses in 22 places ENFORCES it, so the honest deps can
include `t` -- which a language switch legitimately changes, and which would otherwise have
re-fired the toast.
Honest deps that also fix something (5):
- App's module preload was keyed on the account id, so a permission change that alters the
module set without moving the id never re-preloaded. `preload()` is idempotent, so depending
on `me` costs nothing.
- App's access-request nudge now re-issues on a language switch; it used to stay in the old
language until the pending count changed.
- App's diagnostics effect: applyDiagnostics already no-ops on an unchanged effective level,
so picking four fields out by hand was guarding nothing and missed any field added later.
- DataTable's two filter effects: a ref holds the latest onFiltersChange so commitFilters can
be stable, which is what lets the effects name it instead of switching the check off.
Genuine escape hatches (7) moved OUT of eslint-suppressions.json into inline directives that
name the invariant at the site -- the toast handover's render-phase global, the live region's
deliberate arming tick, the docked one-slot component, the popover engine's floating-ui list
state, dnd-kit's per-drag `moved` flag, BackToTop's DOM read and the palette's debounced
announcement. A reader of the code now sees why; a JSON file no one opens does not.
Tests: Avatar (3, new file) and Pager (3) pin the derived-state frames with a layout-phase
probe -- layout effects run before any passive effect, so they read the frame the browser would
paint. Combobox (2) pins the close-clears-query contract and the no-callback-at-mount rule.
All three sets mutation-checked against the effect-based originals.
Suppressions 113 -> 99; exhaustive-deps 45 -> 35.
- PriorityStepper labelled itself with channels.row.* and told every caller
it orders the Feed; Combobox said plex.loading / plex.filter.moreRefine /
sidebar.match on the feed sidebar. The generic strings moved to common.*,
and what a priority MEANS arrives as the stepper's `hint` prop.
uiI18n.contract.test.ts pins components/ui/ to the platform namespaces —
the import boundary could never see an i18n key.
- 32 px-frozen box utilities (w-[150px], max-w-[1600px], left-[18px], …)
became spacing-scale steps (w-37.5, max-w-400, left-4.5): identical at the
default text size, and now they grow with the Settings slider instead of
clipping or re-wrapping their own labels. An eslint rule refuses the px
form beside the older text-[Npx] one, pinned by pxBox.contract.test.ts;
measured in the browser that every new step is generated at its old px.
- chipLane's import-strip regex ran past a side-effect import into the next
statement's `from`, hiding a lane between them; it now stops at the
import's own `;`.
The palette got PageUp/PageDown, and the same crawl stayed everywhere else a list opens under a
control: the sidebar's channel filter, the Plex genre/studio/collection pickers, the filter and sort
menus, submenus of every playlist you own. floating-ui's list navigation has only the arrows and
Home/End.
- `lib/listPaging`: the one definition of a page (the rows wholly in view minus one, a fixed 10 with
no layout) and of where it lands (stops at both ends, never on a row it may not take, looking back
toward the start rather than past it). The palette now uses it instead of its own copy, and
`listNav` takes its scroll-parent helper from here.
- `AnchoredPopover`: one keydown handler on the reference AND the surface, so a combobox (keys on its
input, `aria-activedescendant`) and a roving menu (keys on the focused row) both page. It runs after
floating-ui's own, which has by then switched to keyboard modality and scrolls the new row in. A
disabled row is never the target; a submenu's key does not also page the menu around it; with no
mounted rows (closed, a hover card, a dialog) the key keeps its native meaning.
Measured in the browser: the channel filter shows 8 rows and pages by 7 with the active row in view
after the scroll; a menu pages to its last row and back, the page behind it does not scroll; the
palette still pages by 11 of its 12 visible rows.
The app HAS a platform layer -- AnchoredPopover (22 importers, with
arrows/typeahead/Escape/anchor-flip), QueryState (21), Modal (17),
PageShell, DataTable, Tabs, Tooltip and ~26 more -- but it sat flat among
~160 feature components with nothing marking it as one. Several of those
files describe themselves as 'the one place' or 'canonical' and were
still bypassed by hand-rolled markup, because a layer nobody can see is a
layer nobody uses; three separate inventory passes of this codebase
misread it the same way.
Moves the 33 domain-free modules into components/ui/, rewrites the
imports in 89 files, and makes the boundary a lint rule rather than a
convention: inside ui/ a one-level-up import (a feature component) and
any lib/api slice are errors. The rule was verified to fire on both and
to leave generic lib/ helpers alone. README.md states which side of the
line a component belongs on and why.
No behaviour change: 3x tsc, eslint, knip, prettier and 687 vitest tests
all green; no backend file touched.
