`add_pin`'s IntegrityError handler assumed the unique constraint was the only way in and
re-raised otherwise, so a target row pruned between `resolve_ref` confirming it and the
INSERT (a Plex sync dropping a removed item) tripped the FK and handed the user a 500.
Semantically that is the same "no such thing" the pre-check already returns. Untested: the
race needs two concurrent transactions.
The five per-kind unique constraints had no test at all — the route's own dedupe returns
before reaching the DB, and the migration drift check filters constraint diffs out as noise,
so they could go missing with every lane green.
Frontend, all from the same review: the shelf's unpin row is now `danger` like every other
destructive row in the app; the hero's artwork button says what it will actually do and
names the item instead of always announcing "Play"; the empty-budget message offers a reroll
rather than `StateMessage`'s "Retry", which promised a re-run of something that had not
failed; `setState` and the watch-later toggle catch their rejections instead of leaving an
unhandled promise and a click that silently does nothing.
`StateMessage` gained a `compact` rung, which retires the frontend's only two `!important`
overrides — they existed to beat the primitive's own padding from the call site, and were
the copyable idiom for the next surface that wanted a compact empty state.
Dead vocabulary removed or made load-bearing: `DISCOVER_BUDGETS` was exported, re-exported
and consumed by nothing while `Home.tsx` re-typed the same four bands (a `readonly
DiscoverBudget[]` accepts any subset, so a fifth band would have typechecked green and
rendered no chip); `PIN_KINDS`' value export had no consumer at all; `useComfortPin` no
longer publishes `pinIdOf`/`toggle`, which nothing outside the module calls.
Three comments corrected against the code they describe: a pointer to a `resolve.py` that
was never written, the file header's claim that Home defines no card component of its own,
and the `seen` window still quoting the 8 that was measured and abandoned for 32.
The rest of the review's survivors are logged on ROADMAP.md under "Deferred — E24 epic-end
deep-review (2026-09-08)" — the ones whose dissent was substantive, and the ones whose fix
is wider than the finding.
Third sweep, 20 more sites: the rest of AdminUsers (the access-request
and invite clusters), Scheduler, SettingsPanel, SetupWizard, About, Feed,
KeyGate, OnboardingWizard -- and, importantly, four platform components
that were still hand-rolling their own buttons: Modal's close, Banner's
dismiss, SidePanel's two toggles and QueryState's retry. A platform layer
that bypasses its own primitive is the same defect one level up.
Hand-rolled buttons with their own geometry: 110 -> 39; Button call sites
37 -> 106. What is left is deliberate, and it is the list Button's own
docstring excludes plus two families this pass refused to force: video
overlay controls painted on white/N, drag handles, chip removers,
accent-solid pills, the bg-card family on the signed-out screen, and
sites whose paint is conditional (`suspended ? warn : neutral`) or
otherwise has no variant yet. Forcing those through a className override
would be unsafe without tailwind-merge, which is exactly the hazard this
sprint documented.
3x tsc, eslint, knip, prettier, 689 vitest green; UAT on Settings and the
About dialog (its close button and full-width CTA are both migrated),
clean console.
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.
