Typing "theme" put the channel "The Meltzone Podcast" (matched only through its handle
`@themeltzone`) above every "Theme: …" row, and Enter opened the channel — the palette listed
matches in pure group order and always highlighted the first one.
- CommandPalette ranks each word: label starts with it > elsewhere in the label > only the hint,
keywords or group name; an item ranks by its worst word, then the sum. The group order stays
fixed, rows are ranked inside each group, and the best row overall starts highlighted. The
highlight is held by id and follows the best match until the arrows or the pointer pick a row,
so a channel list landing mid-typing no longer shifts it.
- A11y: result groups are `role="group"` named by their heading; `aria-expanded` is false with
nothing to choose; the listbox stays mounted (hidden) so `aria-controls` never names a missing
element, and "Nothing matches" sits outside it; a polite status announces the count once the
typing pauses.
- `Column`/`FilterMap`/`filterRows`/`isActive` move from `ui/tableHeader` to `lib/tableColumns`,
and the player's auto/loop modes from `playerModalControls` to `lib/playerModes` — three lib
helpers imported the column contract from a ui component, and `playerModalHooks` its types from a
feature component.
- eslint: `lib/` may not import from `components/` at any depth, type-only and re-exports included;
the boundary contract test proves it fires. CLAUDE.md and the ui README say so.
- keymap: `dispatch`'s docblock sat stacked on `matchesShortcut`'s; moved onto `dispatch`.
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.
Introduce the one sort control every content surface will share:
- columnSort.ts gains the SortOption vocabulary + pure pickSort/healSort/
hydrateSort helpers (direction lives in SortState, never in the key).
- SortControl.tsx: the generic dropdown + asc/desc toggle, with an optional
"no sort" choice (tables) and a trailing adornment slot (the feed's reshuffle).
- ColumnSortControl is now a thin wrapper over SortControl (API unchanged, so
Channels + ChannelDiscovery are untouched); optionsFromColumns moved to
lib/sortOptions.ts to keep the component file fast-refresh clean.
- useSortState.ts: the per-account persist/hydrate/heal plumbing the channel
manager and discovery each hand-rolled, ready to replace both.
Pure logic is fully unit-tested (columnSort.test.ts 10 -> 23). Gate green:
tsc/eslint/prettier clean, vitest 93 pass. Feed/Plex/channels migration follows.
