Goal: every styled element in web/src renders through StyleX (@stylexjs/unplugin at build time); Dialog, AlertDialog, Tabs and Select come from react-aria-components; Tailwind is removed. TanStack Router and TanStack Query stay (decided 2026-08-12 after review; the router swap is out of scope permanently, not deferred).

Design written 2026-08-12 against HEAD 91a0aa9. Needs milestone 22 landed (the StyleX and RAC .d.ts surfaces are checked by the TS7 tsc -b).

Inventory this spec rests on: 522 className= occurrences across 31 web/src files; 17 shared class constants in web/src/ui/classes.ts; web/src/styles.css is the single line @import "tailwindcss" (so dark mode is Tailwind 4's default prefers-color-scheme media strategy — no class toggle exists); the Tailwind plugin sits at web/vite.config.ts:3,8; tailwindcss and @tailwindcss/vite are devDependencies (web/package.json:34,44) and appear in neither the runtime closure nor the bundled set of licenses/dependency-identity.txt.

Implementation contract (read first)

Read AGENTS.md, then this spec whole, before session work starts.
web/src/lib/contractSamples.gen.ts and web/src/lib/types.ts are API contract surfaces; this milestone is styling-only and touches neither.
Every session leaves all gates green: npm run format:check, npm run lint, npm run typecheck, npm test, npm run build, npm run assert-bundled (from web/), and zig build test. The release gate (zig build dist + verify-dist, .gitea/workflows/gates.yml) keeps its byte budgets; they are not tight — web/dist is 440,924 bytes raw against the 15 MiB binary budget — but verify-dist remains the arbiter.
assert-bundled fails whenever the bundled npm package set changes. That failure is the license workflow trigger, not an obstacle: review each new package into licenses/inventory.zon, then record the new set in licenses/dependency-identity.txt (procedure in that file's header). Never update the recorded list without the inventory review.

Rulings (binding)

1. Build integration is `@stylexjs/unplugin`, proven before any page moves

stylex.vite() from @stylexjs/unplugin goes into web/vite.config.ts alongside the existing plugins (Tailwind stays until S3). Configuration per the official Vite guide (stylexjs.com/docs/learn/installation/vite): useCSSLayers: true, runtimeInjection: false, dev keyed off the Vite mode. The generated CSS injects into an existing CSS asset, so web/src/styles.css (imported by main.tsx:8) remains the CSS entry for the whole milestone; the dev/HMR virtual-module wiring from that guide is part of S1. The unmaintained community vite-plugin-stylex is forbidden. S1's acceptance proves dev server, vitest run and vite build all handle a StyleX component before S2 or S3 convert anything — this is a gate, not an assumption.

2. Tokens live in `web/src/ui/tokens.stylex.ts`

stylex.defineVars with role names, not raw shades: surface, surface-raised, border, border-strong, text, text-muted (the zinc ramp today), primary and primary-text (blue-600/white), danger, danger-surface, danger-border (the red ramp), focus (blue-600). Each var carries its dark value under @media (prefers-color-scheme: dark) inside defineVars — same media strategy the app has now. No theme toggle, no data-theme attribute.

3. `web/src/ui/styles.ts` replaces `ui/classes.ts`

The 17 exports of web/src/ui/classes.ts (focusRing, insetFocusRing, input, smallInput, button, smallButton, largeButton, primaryButton, largePrimaryButton, rowButton, linkButton, dangerLinkButton, retryButton, th, td, tableWrap, formCard) become stylex.create style objects in web/src/ui/styles.ts, composed at call sites via {...stylex.props(styles.button, extra)}. The milestone-9 accessibility floor restated by milestone-18 ruling 10 carries over verbatim: every interactive element renders the focus ring (:focus-visible outline, 2px, offset 2, focus token; the inset variant for controls flush against panel edges). ui/classes.ts is deleted in S3 when its last importer converts.

4. React Aria scope is exactly four components — end state, not a phase

From react-aria-components: Dialog + Modal (replacing the hand-rolled role="dialog" overlay in web/src/features/clients/ClientEditDialog.tsx:27-28), AlertDialog composition (ruling 5), Tabs (replacing the button-pair tab switcher in web/src/features/local/LocalDnsPage.tsx), Select (replacing the 7 files carrying native <select>: LookupPage, QueryLogPage, RecordsTab, RulesPage, SettingsPage, PrefixesEditor, ClientEditDialog). Everything else — buttons, text inputs, tables, links, banners — stays native HTML styled with StyleX. A native styled <button> is the finished design, not an interim one. S2 wraps the four as shared components: web/src/ui/Dialog.tsx, web/src/ui/ConfirmDialog.tsx, web/src/ui/Tabs.tsx, web/src/ui/Select.tsx, each styled with StyleX through RAC's render-prop state booleans (stylex.props(isSelected && styles.selected)) — never data-attribute selectors, which StyleX cannot express.

5. `window.confirm` dies with the conversion

All call sites become ConfirmDialog (RAC AlertDialog: role="alertdialog", focus trapped, danger-styled confirm button): web/src/features/blocklists/BlocklistsPage.tsx:61, web/src/features/upstreams/UpstreamsPage.tsx:43, web/src/features/rules/RulesPage.tsx:34, and web/src/ui/useCrudForm.ts:49 (which carries the confirm for ZonesTab and RecordsTab). useCrudForm's CrudFormSpec.confirmDelete keeps its signature; the hook returns the dialog state instead of calling window.confirm. The tests that stub confirm today (web/src/features/upstreams/UpstreamsPage.test.tsx:140,144,188, web/src/ui/useCrudForm.test.tsx:102) are rewritten to drive the real dialog: open, assert role="alertdialog" and the entity name in the message, confirm and cancel paths both asserted. BlocklistsPage and RulesPage gain the same coverage for their delete paths.

6. Styling mechanics

stylex.create/stylex.props only. Conditions are boolean-guarded style objects; variants are separate named styles; responsive behavior (the md: sidebar grid in web/src/shell/AppShell.tsx:90-98, the mobile drawer) becomes @media conditions inside style values. No dynamic class-name strings, no clsx-style helpers, no className literals left anywhere in web/src after S3 — className/style attributes appear only as the spread of stylex.props(...) (RAC render-prop className functions included). TanStack Link activeProps/inactiveProps (AppShell.tsx:35-42) pass stylex.props(...).className outputs.

7. Visual contract: drift accepted, structure pinned

No pixel parity requirement and no visual-regression harness. Pinned instead, checkable by reading the converted file against the original: same layout structure (grid/flex relationships, table columns, heading levels), token roles per ruling 2 (zinc surfaces, blue primary actions, red danger), the focus floor of ruling 3 on every interactive element, dark mode via media query, overflow-x-auto table wrappers preserved.

8. License inventory, named per step

S1 adds @stylexjs/stylex (runtime dependency; stylex.props ships in the bundle) to the runtime closure and the bundled set. @stylexjs/unplugin is a devDependency — runtime closure and bundled set untouched by it.
S2 adds react-aria-components and its transitive closure (@react-aria/*, @react-stately/*, @react-types/*, @internationalized/*, @swc/helpers — the exact bundled subset is whatever npm run assert-bundled reports after S2's conversions; every reported name gets a reviewed licenses/inventory.zon entry before the recorded list moves). This is the milestone's largest review surface.
S3 removes nothing from the license files: Tailwind was dev-only and never recorded. The @tanstack/* entries stay untouched.

9. PLAN.md wording moves in S3

PLAN.md:138 "Vite + React + TypeScript + Tailwind; TanStack Router + TanStack Query" → "Vite + React + TypeScript + StyleX + React Aria; TanStack Router + TanStack Query". PLAN.md:235 directory comment updates the same way. Line 562 names loaders and Query only — untouched. No other PLAN amendment.

10. Conversion order is ascending `className` count, one commit per file

So a regression bisects to one page. Counts at spec time:

file	count
lib/InlineError.tsx	2
features/settings/ReadOnlyConfigBanner.tsx	2
features/dashboard/HealthBanners.tsx	2
features/local/LocalDnsPage.tsx	3
features/settings/RestartBanner.tsx	3
features/dashboard/StatCards.tsx	5
routes.tsx	6
auth/LoginPage.tsx	9
features/dashboard/DashboardPage.tsx	9
features/groups/GroupSourcesEditor.tsx	9
features/pause/PauseWidget.tsx	9
features/blocklists/BlocklistForm.tsx	11
features/clients/ClientEditDialog.tsx	11
features/dashboard/DiskCard.tsx	13
features/upstreams/UpstreamForm.tsx	14
features/clients/PrefixesEditor.tsx	15
shell/AppShell.tsx	17
features/live/LiveLogPage.tsx	18
features/dashboard/TimeseriesChart.tsx	21
features/dashboard/UpstreamHealthTable.tsx	21
features/upstreams/UpstreamsPage.tsx	21
features/groups/GroupsPage.tsx	22
features/lookup/LookupPage.tsx	25
features/local/ZonesTab.tsx	26
features/blocklists/SourceStatusSection.tsx	27
features/clients/ClientsPage.tsx	28
features/rules/RulesPage.tsx	31
features/blocklists/BlocklistsPage.tsx	31
features/settings/SettingsPage.tsx	31
features/local/RecordsTab.tsx	34
features/queries/QueryLogPage.tsx	46

S2 takes its owned cluster out of this order (converted together because the RAC wrappers land there); S3 walks the remainder smallest-first.

11. Tests that must change, known in advance

RAC changes DOM and focus behavior; these edits are expected work, not regressions to paper over:

Dialog: ClientsPage.test.tsx (ClientEditDialog now portals into an RAC Modal; queries move to within(screen.getByRole("dialog"))).
Tabs: LocalDnsPage.test.tsx (tab switcher becomes role="tablist"/ role="tab"; getByRole("button", { name: ... }) queries move to getByRole("tab", ...)).
AlertDialog: UpstreamsPage.test.tsx, useCrudForm.test.tsx per ruling 5.
Select: RAC Select renders a button + listbox, not <select>, so getByLabelText(...) + fireEvent.change patterns break in the tests for the 7 Select files (LookupPage, QueryLogPage, LocalDnsPage/RecordsTab, RulesPage, SettingsPage, ClientsPage). They move to userEvent-style open-then-select interactions. All other tests query by role/text and are expected to survive; a test that asserted a Tailwind class is rewritten against role or accessible name.

Sessions

Three sessions, strictly sequential: S1 → S2 → S3. (S2 and S3 both write web/package.json and the license files; the RAC wrappers S3 consumes are built in S2.)

Session S1: StyleX foundation, proven end to end

Owns: web/package.json, web/package-lock.json, web/vite.config.ts, web/src/styles.css, web/src/ui/tokens.stylex.ts (new), web/src/ui/styles.ts (new), web/src/ui/styles.test.tsx (new), licenses/inventory.zon, licenses/dependency-identity.txt.

S1.1 add @stylexjs/stylex (dependency) and @stylexjs/unplugin (devDependency), exact pins; wire stylex.vite() per ruling 1. Tailwind plugin stays.
S1.2 tokens per ruling 2; shared styles per ruling 3. ui/classes.ts is not deleted yet — both vocabularies coexist until S3.
S1.3 styles.test.tsx: render a probe component using stylex.props(styles.button) under vitest; assert a non-empty className lands on the element (proves the transform runs in the test pipeline, since runtimeInjection is off).
S1.4 license entries per ruling 8.

Acceptance (S1):

npm run dev serves a probe page where a StyleX rule visibly applies and edits hot-reload (checked by hand, result recorded).
npm test passes including styles.test.tsx.
npm run build emits StyleX CSS into the web/dist assets; the built index.html page renders with the probe styled.
npm run assert-bundled passes with @stylexjs/stylex in the recorded set; zig build test passes (drift guard agrees).
All remaining gates green.

Session S2: React Aria primitives and their cluster

Owns: web/package.json, web/package-lock.json, web/src/ui/Dialog.tsx (new), web/src/ui/ConfirmDialog.tsx (new), web/src/ui/Tabs.tsx (new), web/src/ui/Select.tsx (new), web/src/ui/useCrudForm.ts, web/src/ui/useCrudForm.test.tsx, web/src/features/clients/*, web/src/features/local/*, web/src/features/upstreams/*, web/src/features/blocklists/BlocklistsPage.tsx and its test, web/src/features/rules/RulesPage.tsx and its test, licenses/inventory.zon, licenses/dependency-identity.txt.

S2.1 add react-aria-components, exact pin; build the four wrappers per ruling 4, styled with tokens and ui/styles.ts.
S2.2 convert the owned cluster fully to StyleX while adopting the wrappers: ClientEditDialog + PrefixesEditor + ClientsPage (Dialog, Select); LocalDnsPage + ZonesTab + RecordsTab (Tabs, Select, ConfirmDialog via useCrudForm); UpstreamsPage + UpstreamForm, BlocklistsPage, RulesPage (ConfirmDialog, Select). No className literal survives in an owned file.
S2.3 window.confirm removal and test rewrites per rulings 5 and 11.
S2.4 license review per ruling 8 — every package assert-bundled names.

Acceptance (S2):

grep -rn 'window\.confirm(' web/src → zero matches. The bare name still appears in three comments in ui/ that record what replaced it, which is why the check is for a call and not for the name.
Delete flows on upstreams, blocklists, rules, zones and records drive a role="alertdialog" element; confirm and cancel both covered by tests.
Tabs on /local-dns expose role="tablist"; keyboard arrow keys move between tabs (asserted in LocalDnsPage.test.tsx).
No className= literal in S2-owned files (grep -c 'className="' <file> = 0; stylex.props spreads excepted).
assert-bundled passes with the RAC closure recorded; zig build test passes.
All remaining gates green.

Session S3: the sweep and the removal

Owns: every web/src file not owned by S1/S2 that carries className= (the ruling-10 remainder: InlineError, ReadOnlyConfigBanner, HealthBanners, RestartBanner, StatCards, routes.tsx, LoginPage, DashboardPage, GroupSourcesEditor, GroupsPage, PauseWidget, BlocklistForm, SourceStatusSection, DiskCard, AppShell, LiveLogPage, TimeseriesChart, UpstreamHealthTable, LookupPage, QueryLogPage, SettingsPage) plus their tests, web/src/ui/classes.ts (delete), web/package.json, web/package-lock.json, web/vite.config.ts, web/src/styles.css, PLAN.md.

S3.1 convert the remainder smallest-first per ruling 10, one commit per file, gates green at every commit.
S3.2 delete ui/classes.ts when its import count reaches zero.
S3.3 remove Tailwind: drop tailwindcss and @tailwindcss/vite from package.json, the plugin from vite.config.ts:3,8, and the @import "tailwindcss" line from styles.css (the file itself stays as the StyleX CSS entry per ruling 1).
S3.4 PLAN.md per ruling 9.

Acceptance (S3):

grep -rn 'className="' web/src returns zero matches. No Tailwind dependency in web/package.json, no plugin in web/vite.config.ts, no @import "tailwindcss" in web/src/styles.css. The word still appears in seven comments in web/src that name the ramps the tokens were taken from and the reset the preflight used to supply; those are the record of where the values came from, so the check is not for the name.
ui/classes.ts is gone; nothing imports it.
Dark scheme still follows prefers-color-scheme (vitest: token var resolves differently under a mocked dark media query, or a recorded manual check in both schemes).
PLAN.md:138 and :235 name StyleX + React Aria; git diff PLAN.md touches nothing else.
All gates green, including zig build dist + zig build verify-dist with -Dweb-dist=web/dist (run once at milestone end).

Orchestrator

Verify S1 acceptance (the ruling-1 gate) before S2 starts; S2 before S3. After S3: full gate set, then a live smoke — zig build a server with the fresh web/dist, click through every page in light and dark scheme, exercise one delete confirm and the local-dns tabs. Record deviations in ## Recorded (implementation).

Module layout

New files:

web/src/ui/tokens.stylex.ts — the design tokens (ruling 2).
web/src/ui/styles.ts — the shared style vocabulary (ruling 3).
web/src/ui/styles.test.tsx — the transform-pipeline probe (S1.3).
web/src/ui/Dialog.tsx, web/src/ui/ConfirmDialog.tsx, web/src/ui/Tabs.tsx, web/src/ui/Select.tsx — the RAC wrappers (ruling 4).

Deleted surface: web/src/ui/classes.ts; the window.confirm calls; the Tailwind dependency pair and its vite plugin line and CSS import.

Acceptance (milestone complete)

All session boxes above.
Zero Tailwind: no dependency, no plugin, no @import, no utility className literal in web/src.
RAC appears in exactly four wrapper files plus their consumers; no other react-aria-components import (grep -rln 'react-aria-components' web/src ⊆ the four wrappers).
Focus ring visible via keyboard on every interactive element of every page (spot-checked live, recorded).
licenses/dependency-identity.txt, licenses/inventory.zon and the bundled reality agree (assert-bundled and zig build test both green).
web/src/lib/types.ts and web/src/lib/contractSamples.gen.ts are byte-identical to HEAD.

Recorded (implementation)

Written during S1 and the S2 hand-off. Each entry is a place the spec was wrong or a decision the spec did not have.

S1 could not put StyleX in the bundle, and its acceptance says otherwise

S1 owns no page file, so no production module imports StyleX and rollup emits none of it. Two S1 boxes — "npm run build emits StyleX CSS into the web/dist assets" and "assert-bundled passes with @stylexjs/stylex in the recorded set" — are therefore unmeetable inside S1 as scoped, and the recorded bundled set is unchanged at the S1 commit. Both were proven instead against a temporary probe component, then deferred to S2, which converts real pages and does change the bundled set. Ruling 8's "S1 adds @stylexjs/stylex ... to the runtime closure and the bundled set" is half right: the closure moves in S1, the bundled set in S2. The inventory entry for StyleX is anticipatory at the S1 commit, which is deliberate — see the styleq entry for why it cannot wait.

The probe results, recorded rather than left as a claim

Against the temporary probe: the built CSS carries @layer priority1..N and the token variables, resolving to #fafafa light and #09090b dark with lightningcss lab() fallbacks. The dev server needs no wiring of its own — the plugin injects <link rel="stylesheet" href="/virtual:stylex.css"> into index.html, so the DevStyleXInject component in StyleX's Vite guide is for frameworks that bypass Vite's HTML transform and is not used here. Editing a token regenerates the virtual stylesheet and the dev server issues a page reload.

S1 wrote outside its owned files, and outside an anti-requirement

The licence guard forced it: licenses/stylex-mit.txt, licenses/styleq-mit.txt and their registration in licenses/licenses.zig, plus the npm_not_shipped array in src/licenses_drift_test.zig. The last contradicts the "no edits ... under src/" anti-requirement below. The anti-requirement is amended, not ignored: src/licenses_drift_test.zig is writable for its licence-fact arrays and, from S2, for the per-package licence change described next. The rest of src/ stays closed.

Apache-2.0 inbound: a decision, not a deduction

react-aria-components 1.20.0 brings eight Apache-2.0 packages (react-aria-components, react-aria, react-stately, @react-types/shared, three @internationalized/*, @swc/helpers) and tslib under 0BSD into an EUPL-1.2 project. The user accepted Apache-2.0 inbound on 2026-08-12 and authorised the guard change it needs. This is recorded as their decision because nothing in the licence settles it: EUPL-1.2's appendix does not list Apache-2.0 — it names GPL, AGPL, OSL, EPL, CeCILL, MPL, LGPL, CC BY-SA, EUPL and LiLiQ — and that appendix governs Article 5 outbound relicensing, not inbound consumption. Any claim that the appendix permits this is false and must not be written into the inventory. src/licenses_drift_test.zig:122 hardcodes a single expected licence and becomes per-package in S2; the guard stays strict, an unexpected licence still fails.

Ruling 8's picture of the React Aria closure is wrong

There are no @react-aria/* or @react-stately/* scoped packages. RAC 1.20.0 ships consolidated react-aria and react-stately. The runtime closure it adds is the eleven packages named above plus aria-hidden, clsx and client-only under MIT — not the "dozens" the ruling anticipated.

Ruling 11's claim about the tab tests is wrong

LocalDnsPage.tsx already renders role="tablist" and role="tab" by hand, so no test query moves from getByRole("button") to getByRole("tab"). What RAC adds there is keyboard arrow-key navigation, which the hand-rolled switcher lacks, and that is what the S2 acceptance box asserts.

`formCard` is a layout change, not a port

space-y-3 set sibling margins on a block container; the StyleX version is a flex column with gap. StyleX cannot express the > * + * selector space-y compiles to, so gap is the only mechanism available. Both call sites (RecordsTab, ZonesTab) are plain vertical form stacks, where the difference in child sizing and margin behaviour does not show. Recorded against ruling 7, which pins layout structure.

S2 needed two build-config changes the spec did not anticipate

Both are in files S1 and S3 own, both were forced, and neither is optional.

web/vitest.setup.ts (new) plus setupFiles in web/vite.config.ts: jsdom implements no CSS interface at all, and React Aria's collection code calls CSS.escape unguarded when it looks an item up by key (react-aria/dist/private/selection/utils.mjs:22). Every RAC Select and Tabs test threw Cannot read properties of undefined (reading 'escape') before this landed. The setup file implements CSSOM's serialize an identifier algorithm rather than approximating it, because a wrong escape would break the key lookups silently instead of loudly.

The @ alias passed to stylex.vite() in web/vite.config.ts: StyleX resolves the .stylex.ts theme file itself and cannot see Vite's resolve.alias, so import { colors } from "@/ui/tokens.stylex" in a feature file failed the build with "Could not resolve the path to the imported file". Relative imports were the alternative; passing the alias keeps the repo's @/ convention instead.

RAC Select changes the accessible name of a labelled control

useSelect labels the trigger button with aria-labelledby="<value> <label>", so a select labelled "Type" showing "A" has the accessible name "A Type", and getByLabelText("Type") no longer finds it. Converted tests query getByRole("button", { name: /Type$/ }) and read the options by opening the listbox. RAC also renders a hidden native <select> for form submission; it sits inside an aria-hidden container, so role and label queries skip it.

The RAC anti-requirement forbids parts of a component it requires

Select.tsx imports RAC Button, Popover, Label, ListBox, ListBoxItem and SelectValue. The anti-requirement below names Button and Popover among the components RAC must not bring. Those two are not adopted components here — RAC composes a Select out of exactly these parts, and there is no RAC Select without them. The anti-requirement is amended: it forbids adopting a RAC component as an app-wide primitive, and the internal parts of the four adopted components are permitted where no file outside their wrapper imports them. That last clause is the check that keeps the scope honest, and it holds: react-aria-components is imported only by the four ui/ wrappers. A RAC Button in a feature file would still be a breach.

The focus-ring floor was briefly amended on a false premise

S2 left the Select's options with their outline removed, showing keyboard focus as a background inversion alone. This section previously amended ruling 3 to excuse that, arguing RAC drives option focus through an isFocused render prop so a :focus-visible rule could never match. That argument is wrong. useSelectableItem gives options a roving tabIndex and focuses the option's own DOM node (react-aria/dist/private/selection/useSelectableItem.mjs:64), which ListBoxItem spreads onto its element — so :focus-visible matches and the ring was simply missing. The amendment is withdrawn and ruling 3 stands unchanged. Select.tsx now composes the shared inset ring onto every option: inset because an option flush against a scrolling popover clips an outset outline, and recoloured to primaryText on the highlighted row because the focus token is the same blue that row paints behind it. The inversion stays as the listbox convention; it is no longer the only indicator.

Two notes for S3

textMuted resolves to zinc-400 in dark mode. Several current text-zinc-500 call sites carry no dark override and stay zinc-500, so the token cannot replace those without a shade shift — decide per call site rather than sweeping.

Vitest began reporting "Tests closed successfully but something prevents Vite server from exiting" with the StyleX plugin in the pipeline. The suite passes and exits 0. It should not be allowed to become the accepted baseline.

Both S3 notes are now settled

The vitest warning is fixed, and it was not our code. Bisecting a trivial one-assertion test against a bare config showed react() exits clean and stylex.vite() does not. @stylexjs/unplugin@0.19.0's lib/es/vite.mjs:59 starts a 150ms setInterval in configureServer to poll its CSS store for HMR, and clears it from the close event of server.httpServer. A probe plugin confirmed vitest resolves httpServer to null, because it runs the dev server in middleware mode — so the timer is never cleared and holds the event loop open until vitest kills the worker on a ten-second timeout. web/vite.config.ts now strips that one hook when process.env.VITEST is set; the transform hook, which the tests do need, is untouched, and ui/styles.test.tsx still proves it runs. npm test reports 31 files and 183 tests passed, with no warning, and exits 0.

textMuted was swept; here is the per-call-site judgement. Measuring the two shifts against their grounds settles it in opposite directions:

39 call sites were a flat text-zinc-500 with no dark override. On the dark ground that measures 4.12:1, which fails WCAG AA. The token's zinc-400 dark value measures 7.56:1. The sweep repaired a real accessibility defect there, so it stands, and the token comment now records why.
4 call sites were text-zinc-600 dark:text-zinc-400 — already adaptive. The sweep moved their light value to zinc-500, from 7.40:1 to 4.62:1. That clears AA by a hair on small text: the query-log table header, the dashboard period button, the inactive nav item and the chart legend. It buys nothing, so a second token textSecondary (zinc-600 light, zinc-400 dark) restores the original pair at exactly those four.

Contrast was computed from the tokens' own oklch values through linear sRGB to WCAG relative luminance, not read off a chart.

The reset's font stack is not Tailwind's, deliberately

Tailwind is uninstalled, so its default stack cannot be reproduced from the tree, and ruling 7 accepts the metric drift. One part is not drift: Select.tsx renders U+25BE for its chevron, and Segoe UI does not carry that glyph, so on Windows the stack has to reach a font that does. "Segoe UI Symbol" and "Noto Sans Symbols 2" are appended for that glyph. No emoji families are listed, because the app renders no emoji.

Two review findings closed by decision, not by a change

Both were put to Mokhtar Mial on 2026-08-12 and both are closed. Neither is to be re-opened by a later review reading the history and inferring an oversight.

0f58966 carries a README.md edit that was already in the working tree and is not part of the srOnly work its message describes. The content is intact and only the attribution is wrong; rewriting published history to correct that was declined.

Ruling 10 asks for one commit per file in ascending className count. S3 did not hold to the order strictly. Bisectability does not depend on it and the commits were already published, so the order stands as it is.

Anti-requirements

No router or query changes: TanStack Router and TanStack Query stay, untouched. That decision is closed.
No RAC beyond Dialog, AlertDialog, Tabs, Select — no RAC Button, TextField, Table, Menu, DatePicker adopted as an app primitive. Native elements styled with StyleX are the end state. The internal parts of the four adopted components (Button, Popover, Label, ListBox, ListBoxItem, SelectValue inside Select) are permitted, and only inside their own wrapper file — see the recorded amendment above.
No runtime style injection (runtimeInjection: false stays), no CSS-in-JS at runtime, no styled-components-like patterns.
No dynamic class-name assembly, no clsx/classnames dependency, no Tailwind-compatibility shim.
No theme toggle, no data-theme, no stored preference — media-query dark mode only, as today.
No redesign: layout structure is pinned by ruling 7. Drift in shades and spacing is accepted; new page structures are not.
No visual-regression harness, no screenshot tooling.
No edits to web/src/lib/types.ts, web/src/lib/contractSamples.gen.ts, web/src/lib/api.ts, or anything under src/ (the Zig tree).
No vite-plugin-stylex (unmaintained community plugin).

30 KiB Raw Blame History

Milestone 23: StyleX and React Aria replace Tailwind
