  configuration rows, names the tables and counts, and applies it only with
  the new `--allow-delete` flag. Additive and edit-in-place imports need no
  flag.
- **Regex rules.** Rules gain a third kind, `regex`, beside `exact` and
-  `wildcard`, for per-group allow and block patterns such as `^ad[0-9]+-`. The
-  engine is homegrown and linear-time by construction, so no pattern can make
-  matching blow up; backreferences and lookaround do not exist, and a bad
-  pattern is refused at insert time with the limit it hit. Matches appear in
-  `/api/lookup` and the query log as `rule_allow_regex` / `rule_block_regex`.
-  Regex still comes only from you: regex lines in downloaded lists stay
-  counted and skipped.
- **Blocklist exception lines are honored.** An Adblock-Plus `@@||name^` line
-  in a downloaded list now lifts that name — and its subdomains — out of what
-  the attached lists block. Exceptions sit below every rule you wrote: a
-  downloaded list can reopen only a hole another downloaded list dug, never
-  override an operator decision. Each source reports how many it carried.
- **Browser-only lines are counted where you can see them.** Every source now
-  reports how many of its lines nxdns skipped as syntax with no DNS meaning —
-  cosmetic filters, `$`-modifier rules — beside the existing skipped-regex
-  count. Both blocklist tables show the number and the UI explains the
-  difference: a list whose skipped-unsupported count dwarfs its domain count
-  is written for browser extensions, and its DNS or hosts variant will block
-  more. Previously such a list compiled to almost nothing and looked clean.

 - `nxdns import --force` is renamed `--allow-delete`.
 - A fresh install no longer seeds from `/etc/nxdns/config.zon` by presence.

-### Fixed
-
- **A list switching a name between its exact and wildcard forms never took
-  effect.** The compiled-list checksum hashed the exact and wildcard bodies as
-  one unseparated byte stream, so a list carrying `a.example` and the same
-  list carrying `*.a.example` produced the same digest, and the refresh kept
-  the old compiled files. The checksum now separates the bodies. Every source
-  recompiles once on its first refresh after the upgrade; no re-download of
-  unchanged content is forced beyond the refresh's normal fetch.
- **A refresh could store stale skip counts.** When a refresh found the list
-  content unchanged, it wrote the previously stored skip counters back to the
-  database while showing the fresh ones in the UI, and the next restart
-  reverted the numbers to the stale copy. All counters now persist from the
-  fresh compile.
- An Adblock-Plus entry with embedded whitespace
-  (`||good.example bad.example^`) compiled into an entry no query could ever
-  match. Such lines are now counted as unsupported instead.

 ### 2.2 Out of Scope (permanent scope decisions, not deferrals)

- Regex from downloaded blocklists. A list is other people's code running on the household's DNS, and the engine exists for rules the operator wrote. Regex lines in blocklists stay counted and skipped, and the skip count stays surfaced in the UI. (Operator regex rules themselves are **in** scope as of milestone 21: the ReDoS objection that once ruled them out is answered by `filter/regex.zig`, a homegrown Pike VM whose running time is bounded by program length × name length by construction, with no dependency and no backtracking. It is reached only after every hash and wildcard level has missed, and only on a cache miss.)
- ABP syntax beyond domain anchors and `@@||name^` exceptions. `$dnstype`, `$dnsrewrite`, `$client`, `$denyallow` and every browser modifier stay unsupported and counted; the one tolerated modifier is a `$important` suffix on an exception line, which changes nothing about where that exception lands.

No TOML: a third-party parser plus a hand-written serializer is two failure surfaces in the correctness-critical round-trip path, bought for syntax familiarity.
- The invocation picks the authority, and nothing else does (m20): `nxdns run` makes the database the configuration, `nxdns run --config FILE` makes the file the sole source and refuses the API routes that would edit configuration. There is no seeding and no first-start special case.

 ### 3.8 Blocklist Storage (Decision A)

 Blocklist domains are **not** stored in SQLite — they are a cache of re-downloadable remote artifacts, not config or state:

- Each source compiles to `/var/lib/nxdns/blocklists/<source_id>.list`: normalized, one domain per line, small header (source URL, fetch time, counts, checksum). Wildcard/regex/exception-flavored lines: wildcards go to `<source_id>.wild`, ABP exceptions (`@@||name^`) to `<source_id>.allow`; regex lines and browser-syntax lines nxdns cannot translate into a DNS decision are counted + skipped, both counts in metadata → UI. The checksum covers the three bodies in that order, each followed by a separator byte so that moving a name between bodies — an upstream switching `a.example` to `*.a.example` — changes the digest and forces a republish.

 - `config.db` keeps source **metadata only** (`blocklist_sources`).
 - Startup + post-update: parse files into the immutable in-memory matcher (RCU swap, §9.5).
 - Corruption recovery is per-file: checksum mismatch → re-download one list.

 ### 3.9 Rule Model (Decision B)

-Rule kinds: `exact`, parent-walk (implicit via candidate chain), `wildcard` (`*` segment patterns, e.g. `*.doubleclick.net`, `ads.*.example.com`), `regex` (the linear-time engine of `filter/regex.zig`, matched unanchored against the whole normalized name). Actions: `allow` | `block`. Kind is an explicit column, so a fourth kind widens one `CHECK` and touches no other table. A regex pattern is stored exactly as written — it is not a name, so it is never lowercased or dot-stripped — and is compiled at both edges: `config/validate.zig` refuses a bad one with the limit it hit, and `filter/rules.zig` compiles it once per snapshot.
+Rule kinds: `exact`, parent-walk (implicit via candidate chain), `wildcard` (`*` segment patterns, e.g. `*.doubleclick.net`, `ads.*.example.com`). Actions: `allow` | `block`. Kind is an explicit column — the model is extensible without breakage, but regex stays out of scope (§2.2).

-## Recorded (anchor re-verification, 2026-08-12)
-
-The spec was written against `ffc3ca6` and verified against `a8e0fe4`. It was
-re-verified a third time after milestones 22 and 23 landed (TypeScript 7,
-Tailwind removed, StyleX and React Aria). Findings, all folded into the
-rulings above:
-
- **No Zig file changed** between `a8e0fe4` and this re-verification. Every
-  Zig anchor holds; six ranges are off by a line or two but still contain what
-  the spec names. The schema is still at version 2, so migration steps 3 and 4
-  are genuinely new.
- The rules-page kind selector is no longer a `<select>`. It is a
-  `KIND_OPTIONS` array feeding `web/src/ui/Select.tsx`, a React Aria wrapper
-  (ruling 7 rewritten).
- `migrations.zig:349` pins `target_version` and is unnamed by the original
-  spec. S1 moves it to 3, S3 to 4.
- `exception_count` has two UI sites, not one, so S1 owns `BlocklistsPage.tsx`
-  (ruling 4 rewritten).
- The checksum sentence has three copies, not one (ruling 3 rewritten).
- `patternIsValid`'s error set cannot carry the engine's three error tags as
-  written (ruling 6 rewritten).
- `PLAN.md:99` documents two compiled bodies and goes stale with ruling 3
-  (ruling 8 rewritten).
- `tools/bench.zig:158` reads `.rules = &.{}`, so the filter bench loads no
-  rules today.
- `web/vitest.setup.ts` polyfills `CSS.escape`; without it, a test that opens
-  the React Aria selector throws under jsdom.
- `npm run build` gained `scripts/assert-css-layers.mjs`, which fails on any
-  rule outside a cascade layer. A pure StyleX change cannot trip it.
-
-## Recorded (implementation)
-
-Deviations and findings from the build, the Codex review rounds and the live
-smoke. Everything here is folded into the code; nothing is outstanding.
-
- **Regex scratch is on the caller's stack, not in `Program`.** `std.Io.Threaded`
-  means several query threads share one snapshot, so the Pike VM's two thread
-  lists cannot live in the compiled program. `matches` takes its scratch from
-  the caller's frame, which keeps `Program` immutable and shareable and keeps
-  the match path allocation-free.
- **`{n,}` is legal and `\` + any ASCII punctuation is legal.** Ruling 5 named
-  neither. Quantifier-on-quantifier (`a+?` read as `(a+)?`) is `BadPattern`:
-  the first Codex round found `a+?` compiling to something that matched
-  everything.
- **Embedded whitespace was accepted on the anchored ABP forms.** A line such
-  as `||good.example bad.example^` reached the compiler, which lowercases and
-  length-checks but does not reject a space, and wrote an entry only a query
-  carrying the same space could match. `compiler.zig` passes `.wildcard` and
-  `.exception` text to `addCandidate` whole, which is why the space survived
-  there. `parser_abp.isNameCandidate` now refuses whitespace and control bytes
-  on those two paths.
-
-  The bare-name path deliberately does **not** use it. `compiler.zig:93-98`
-  tokenizes `.domain` text on whitespace and adds each field separately, so a
-  bare line carrying a space was never broken — it produced two valid entries.
-  Since `detectFormat` assigns one format per source, a mostly-ABP list that
-  also carries hosts-style lines depends on exactly that tokenizer to keep
-  them working. The first attempt at this fix applied the helper to all three
-  paths and silently dropped that fallback; the second Codex pass caught it.
-  Two tests now pin it: a parser test that the bare form stays `.domain`, and
-  a compiler test that an ABP-classified list carrying `0.0.0.0 ads.example`
-  still emits `ads.example`. The third pass pointed out that the parser test
-  alone would pass even if the compiler stopped tokenizing, which is the
-  behaviour the fallback actually depends on.
- **The `.allow` body left stale enumerations behind it.** Adding a third
-  compiled body — and with it a fourth temporary, `.allow.tmp` — updated the
-  production code but not every place that lists the file names. The third review pass found four: two `manager.zig` tests that
-  spell the names by hand, the orphan-sweep fixture in
-  `filter_integration_test.zig`, and `PLAN.md` §3.13 and §5. The
-  `manager.zig` table-driven test was worse than stale — it iterates
-  `source_file_suffixes` itself, so deleting an entry changes the code and the
-  test's expectations together and everything still passes. The whole repo was
-  then swept for the pattern rather than the four instances patched, which
-  turned up seven more — including the reload-cancellation test, whose fixture
-  wrote no `.allow` file at all, so the third of `loadSource`'s three read
-  sites was never exercised. A fourth pass then found test 10e comparing only
-  `.list` and `.wild` across a restart, so a restart that rewrote the exception
-  body alone would have stayed green. A `comptime` assertion on
-  `source_file_suffixes.len` now breaks the build when a suffix is added or
-  removed without updating the hand-written tests.
- **A pre-existing flake in the required suite.** `src/cli.zig:1538` asserted
-  `std.mem.count(u8, text, "OK") == 0` over output that embeds the temporary
-  directory path. `std.testing.tmpDir` names that directory with base64 over
-  12 random bytes, whose 64-symbol alphabet includes uppercase: 15 adjacent
-  positions each carry `OK` with probability 1/4096, so about one run in 273
-  fails a test that has nothing to do with naming. It surfaced during
-  this milestone's watched-fail injections. The assertion now checks that no
-  line *starts* with a verdict, which covers both `OK:` and
-  `OK upstreams[...]` and cannot match a path segment. Reproduced and fixed
-  outside the milestone's scope because a randomly failing required gate
-  devalues every green run after it.
- **`PLAN.md` still described the seed-once config model.** Seven sites said or
-  implied that the first start seeds the database from `/etc/nxdns/config.zon`,
-  which milestone 20 replaced with the two authority modes selected by the
-  presence of `--config`. One of them listed a `config/bootstrap.zig` that does
-  not exist — the module is `loader.zig` plus `reconcile.zig`. The claim was
-  checked against `src/app.zig:339`, not just against the docs. This is
-  milestone-20 drift found while fixing the milestone-21 echoes in the same
-  document, and corrected because PLAN is the source of truth a later session
-  builds from.
- **`PLAN.md` §12.1 held a config sample nobody could load.** It described an
-  `.upstream.servers` field that never existed and omitted the required
-  `.groups` and `.upstreams`. The section now points at
-  `docs/reference/configuration.md` and `nxdns export` and keeps only a
-  skeleton: a second copy of the schema is what produced the drift, so the
-  copy is gone rather than corrected.
- **`PLAN.md` §7.1 claimed blocklist entries never parent-walk.** Two of the
-  three list levels do: wildcard entries match every proper parent, and
-  exception entries walk the candidate chain, which is why
-  `@@||good.ads.example^` also lifts `y.good.ads.example`. Only domain entries
-  match the query name alone.
- **`src/config/model.zig`'s header described the retired bootstrap** and
-  omitted `exception_count` from its list of runtime columns. The first attempt
-  at correcting it introduced a new error — it called import a wholesale
-  replacement set against reconciliation — which the sixth pass caught.
-  `import.zig:3` is explicit that import has been a thin wrapper over
-  `reconcile.zig` since milestone 20, so there is one declarative write path,
-  not two, and it preserves the runtime state of every row the input still
-  names (`reconcile.zig:1139`). A seventh pass then corrected two more claims
-  in the same header: `Config` is the whole shape of a config file but not the
-  only shape the repositories accept (the API writes through `RuleInput`,
-  `ClientInput`, `ClientEdit`), and compiled-body reuse turns on the preserved
-  source id and checksum rather than the counters — `loadSource` names the
-  files after the id and accepts them only against the stored checksum.
- **`PLAN.md` §11.2 presented the v1 DDL as the live schema.** It predates
-  three migrations, so it lacks `upstreams.tls_name` and
-  `blocklist_sources.exception_count` and its `kind` CHECK admits only
-  `exact` and `wildcard` — implementing against it would produce a database
-  that rejects every regex rule this milestone added. The section is now
-  labelled the v1 baseline and points at `config_schema.zig` and
-  `migrations.zig`, with the three steps named.
- **`INSTALL.md` said the service reads `config.zon` "on the first start".**
-  Neither authority mode behaves that way: under `run --config` the service
-  reads it on every start, and under database authority `nxdns import` reads it
-  while a bare `nxdns run` never does. The sentence justified a file mode, so
-  an operator tightening permissions after first boot would have broken the
-  next file-mode restart. More milestone-20 drift. The claim had a second copy
-  in `docs/how-to/install-with-systemd.md`, found only because the seventh pass
-  looked for it after the first copy was fixed.
- **`PLAN.md` §7.1 and the Phase 5 summary missed this milestone's own
-  additions.** The evaluation sequence went straight from operator rules to
-  blocklist domains, omitting the exception level, and the matcher was still
-  enumerated as exact/parent/wildcard with no regex. Ruling 8 required these
-  echoes and S3 did not reach them.
- **The UI trimmed regex patterns.** `RulesPage.onSubmit` applied
-  `pattern.trim()` to every kind, so a regex created in the UI did not store
-  the bytes an identical `POST /api/rules` would. It now trims only `exact`
-  and `wildcard`, where the server normalizes anyway. No client-side
-  whitespace rejection was added: `" foo|bar"` still has a live `bar` branch,
-  so refusing it would over-reject, and the server stays the authority on
-  pattern validity.
- **The rule pattern field opted into mobile autocapitalization.** An
-  autocapitalized regex validates and then silently never matches, because
-  query names are lowercase and a regex is never normalized. The field now
-  sets `autoCapitalize="none"`, `autoCorrect="off"`, `spellCheck={false}`.
- **`RuleSet.build` received the snapshot arena for its temporaries.** An
-  arena reclaims only its most recent allocation, so every `defer …deinit`
-  inside `build` was a silent no-op and the scratch survived until snapshot
-  teardown, uncounted by `memoryBytes()`. `build` now takes a permanent and a
-  scratch allocator, and `matcher.zig` passes `arena` and `gpa` respectively.
-  Regex programs compile into scratch and are copied across by a new
-  `Program.clone`, which keeps `regex.zig` a single-allocator engine and
-  leaves `compile`'s signature — and therefore `config/validate.zig` and the
-  fuzz target — untouched.
-
-  Measured on 16 groups each holding 256 regex rules of 254 bytes,
-  4096 wildcards and 2048 exact rules, with no blocklist sources:
-  arena capacity fell from 135,662,440 to 12,686,214 bytes against an
-  unchanged `memoryBytes()` of 11,058,791, so the ratio of real to reported
-  went from 12.27× to 1.15×. The hidden footprint per snapshot fell from
-  118.83 MiB to 1.55 MiB, so 117.28 MiB went away. A reload holds two
-  snapshots, so it was carrying twice that.
-  `memoryBytes()` needed no change: the formula was always right about what
-  the `RuleSet` retains, and the divergence was arena capacity the formula
-  does not claim to describe. The residual 1.15× is arena node headers and
-  page rounding, which `memoryBytes` documents itself as excluding.
-
-  The guard is `the build's temporaries stay out of the permanent allocator`,
-  which asserts `arena.queryCapacity() < 2 * set.memoryBytes()` and passes
-  `scratch` as `testing.allocator`, so a permanent allocation wrongly taken
-  from scratch also fails as a leak. It was watched failing with the split
-  reverted.
- **An interactive `--fuzz` session cannot run on zig 0.16.0.** Building any
-  fuzz target with `-ffuzz` fails inside the stock
-  `/usr/lib/zig/compiler/test_runner.zig:566`, which passes a
-  `*builtin.StackTrace` to `debug.writeStackTrace` where a
-  `*const debug.StackTrace` is wanted — two distinct struct declarations. The
-  failure is entirely inside the toolchain and reproduces on `compiler-fuzz`,
-  a target this milestone did not touch. Corpus replay under `zig build test`
-  is unaffected and remains the evidence for the step-bound property.
- **`api.md` gained a block-reason table.** The milestone added three reason
-  tags and no doc page enumerated any of them. The table lists all nine in
-  evaluation order plus `none` and the `cname:` prefix.
- **Two comment sites still counted three temporaries.** `manager.zig` line 40
-  (the `refresh_lock` invariant) and line 1293 (`pruneOrphans`) both omitted
-  `.allow.tmp`. Each presents itself as exhaustive, so a maintainer could have
-  added an `.allow.tmp` writer outside `refresh_lock` and let the orphan sweep
-  delete it mid-compile. `sourceFileId` and `source_file_suffixes` already
-  matched all four.
- **The rule pattern placeholder named only two kinds.** Ruling 7 requires the
-  web contract to name the third kind everywhere it names the first two, and
-  the placeholder read `ads.example.com or *.example.com`. It now carries a
-  regex example too.
- **Two pre-existing tutorial errors surfaced during the docs sweep.**
-  `tutorial/first-run.md` step 14 claimed the compiled list stays on disk when
-  it is in fact pruned (real output: `pruned orphaned blocklist file 1.allow`,
-  `1.wild`, `1.list`), and step 11 named `ads.doubleclick.net`, which
-  StevenBlack no longer carries.

-# Milestone 22: TypeScript 7
-
-Goal: move the web toolchain from TypeScript 6.0.3 to TypeScript 7.0.x (the
-native compiler, GA 2026-07-08). One devDependency bump; every web gate and
-the release pipeline stay green.
-
-Design written 2026-08-12 against HEAD `91a0aa9`. TypeScript 7.0.2 is
-`typescript@latest` on npm at spec time; the milestone pins whatever 7.0.x is
-current when the session runs.
-
-## Implementation contract (read first)
-
- Read `AGENTS.md`, then this spec whole, before session work starts.
- `web/src/lib/contractSamples.gen.ts` is generated; it is type-checked by
-  `tsc -b` but never hand-edited. If TS7 rejects it, the fix goes in the
-  generator (`AGENTS.md` regeneration procedure), not the file.
- No license work: `typescript` is a devDependency, absent from both the
-  runtime closure and the bundled set in `licenses/dependency-identity.txt`.
-  The Zig drift guard (`src/licenses_drift_test.zig`) must still pass —
-  it recomputes from `web/package-lock.json` and dev-only changes are
-  invisible to it.

-`baseUrl`-as-alias) are present. `tsconfig.json` is a two-entry project
-reference; TS7 supports `tsc -b` and project references. The session changes
-a tsconfig only if `tsc -b` errors demand it, and records any such change in
-`## Recorded (implementation)`.
-
-### 3. Known TS7 edge: `skipLibCheck` no longer hides parse-level .d.ts errors
-
-Both tsconfigs set `skipLibCheck: true`. Under TS7 that still skips type
-checking of `.d.ts` files but not parse-level errors in them. If a dependency
-`.d.ts` fails to parse, the fix is a dependency patch bump or an upstream
-issue reference recorded in the spec — never a copied-and-edited local
-`.d.ts`.
-
-### 4. Nothing else in the toolchain consumes the TS compiler
-
-Verified at spec time: `oxlint` (own parser), `vite`/`vitest`
-(esbuild transpile, no type checking), `prettier`, and
-`@vitejs/plugin-react` run no `tsc` and load no `typescript` API. The only
-consumer is the `typecheck` script (`web/package.json:12`, `tsc -b`), run in
-CI at `.gitea/workflows/gates.yml:113-114`. TS7 has no stable programmatic
-API until 7.1; nothing in this repo needs one.
-
-## Sessions
-
-One session.
-
-### Session S1: the bump
-
-Owns: `web/package.json`, `web/package-lock.json`, and — only if ruling 2
-forces it — `web/tsconfig.app.json`, `web/tsconfig.node.json`,
-`web/tsconfig.json`.
-
- S1.1 bump per ruling 1; `npm install`.
- S1.2 run, in order: `npm run format:check`, `npm run lint`,
-  `npm run typecheck`, `npm test`, `npm run build`, `npm run assert-bundled`
-  (all from `web/`).
- S1.3 `zig build test` (the licenses drift guard and the contract-samples
-  guard run inside it).
-
-Acceptance (S1):
- [ ] `web/node_modules/.bin/tsc --version` reports 7.0.x.
- [ ] `npm run typecheck` exits 0 with no tsconfig change, or the change is
-      recorded with the TS7 error text that forced it.
- [ ] All six web gate commands exit 0.
- [ ] `zig build test` exits 0.
- [ ] `git diff` touches only the files S1 owns.
-
-## Module layout
-
-New files: none. Deleted surface: none.
-
-## Acceptance (milestone complete)
-
- [ ] All S1 boxes.
- [ ] `licenses/dependency-identity.txt` is byte-identical to HEAD.
-
-## Anti-requirements
-
- No other dependency bumps ride along — not oxlint, not vite, not vitest,
-  not `@types/*`.
- No tsconfig flag additions or "modernization" beyond what a TS7 error
-  forces.
- No typescript-eslint, ts-jest, or any tool needing the TS programmatic API
-  (unavailable until 7.1, and unwanted regardless — oxlint is the linter).
- No `tsgo` binary references anywhere: the binary is `tsc`, scripts stay as
-  they are.
- No edits to `web/src/**` — a source change to satisfy the new compiler is a
-  finding to record and fix, not silently absorb, unless `tsc -b` fails
-  without it; then it is recorded in `## Recorded (implementation)`.

-# Milestone 23: StyleX and React Aria replace Tailwind
-
-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).

-# Milestone 24: `skipped_unsupported` is persisted, surfaced and explained
-
-Goal: close the compile-pipeline silent drop that misleads the operator. `Counts.
-skipped_unsupported` (`src/filter/compiler.zig:34`) is counted on every compile
-(compiler.zig:92) and then discarded on the happy path — it reaches the
-compiled-file header and the `NoValidEntries` error text, but no database
-column, no API field and no UI cell. Its sibling `skipped_regex` reaches all
-three. A blocklist made almost entirely of cosmetic browser filters therefore
-compiles to almost nothing and looks, in the UI, exactly like a clean list.
-AGENTS.md forbids exactly this ("no silent drops"). The milestone persists the
-count, surfaces it everywhere `skipped_regex` is surfaced, and explains to the
-operator why the two skip counters are different facts.
-
-Design written 2026-08-13 against HEAD `21571e4`, revised after a Codex review
-of the first draft.
-
-## Implementation contract (read first)
-
- Read `AGENTS.md`, then this spec whole, before session work starts.
- **The v1 baseline is editable and there is no migration step.** As of commit
-  `21571e4`, `src/storage/migrations.zig` holds exactly one step and
-  `target_version` is 1 (migrations.zig:29-36). nxdns has zero installs; the
-  baseline freezes at v0.1 (`config_schema.zig:6-12`, PLAN §3.7, §11.2). The
-  new column is one line edited into `config_schema.ddl_v1` plus the identical
-  line in PLAN §11.2, which is kept byte-identical to it. A diff that adds a
-  `ddl_v2` or a second `Step` is wrong and must be reverted, not merged.
- After the API shape change, regenerate the contract samples
-  (`web/src/lib/contractSamples.gen.ts`; procedure in AGENTS.md — the
-  `zig build test -Dintegration -Dcontract-samples-out=...` command, never a
-  hand edit) and update `web/src/lib/types.ts` to match.
- No new `src/**.zig` files, so `src/tests.zig` and `build.zig` are untouched.
-
-## Rulings (binding)
-
-### 1. The column is `skipped_unsupported_count`, one edited line, no step
-
-`skipped_regex_count` (config_schema.zig:63) sets the convention; the new
-column follows it. In `config_schema.ddl_v1`, directly after the
-`skipped_regex_count` line inside `CREATE TABLE blocklist_sources`:
-
-```sql
-    skipped_unsupported_count INTEGER NOT NULL DEFAULT 0,
-```
-
-The identical line goes into PLAN §11.2 after PLAN.md:421 — that section is
-kept byte-identical to `ddl_v1` and currently is (verified: the fenced SQL
-matches the Zig string literal line for line).
-
-Consequence to accept, not to fix: a development database stamped version 1
-before this edit will fail the first `SELECT` naming the column with "no such
-column", because the stamped version equals `target_version` and the step never
-reruns. That is the documented pre-v0.1 contract (`config_schema.zig:6-12`) —
-delete the scratch database. Do not add fallback SQL, `PRAGMA table_info`
-probing, or a migration step to paper over it.
-
-The baseline test "a fresh database reaches the baseline with every v1 column
-and rule kind" (migrations.zig:266-283) gains
-`try testing.expect(try columnExists(&database, "blocklist_sources", "skipped_unsupported_count"));`
-beside the existing `exception_count` probe.
-
-### 2. The repo persists it beside `skipped_regex_count`
-
-`src/storage/repositories/sources_repo.zig`, mirroring `skipped_regex_count`
-exactly (no default on either struct field, so every construction site fails
-to compile until it names the count — that is the visibility this milestone is
-about):
-
- `SourceRow` (sources_repo.zig:80-97) gains `skipped_unsupported_count: i64`
-  after `skipped_regex_count`.
- `SourceStats` (sources_repo.zig:99-110) gains the same field.
- `row_columns_sql` (sources_repo.zig:112-117) appends
-  `skipped_unsupported_count` to the SELECT list (index 11);
-  `readSourceRow` (sources_repo.zig:128-148) reads it with
-  `stmt.columnInt(11)`.
- `update_stats_sql` (sources_repo.zig:159-164) adds
-  `skipped_unsupported_count = ?8`; `updateSourceStats`
-  (sources_repo.zig:168-179) binds it.
- The module doc comment (sources_repo.zig:3-5) adds the column to its list of
-  server-produced facts, and so does the `src/config/model.zig:14` doc comment
-  that repeats that list.
-
-**The sum at sources_repo.zig:318 includes the new column.** That sum lives in
-the test "insertBlocklistSource leaves the runtime columns at their defaults";
-it exists to prove an insert leaves every runtime counter at 0, and the new
-column is a runtime counter. This is a deliberate decision, not an oversight:
-no production query sums these columns into a "total entries" figure, and none
-may start to — `skipped_regex_count` and `skipped_unsupported_count` count
-lines *not* written, unlike `domain_count`, `wildcard_count` and
-`exception_count`, so any future entries total must exclude both. The test sum
-asserts defaults, which is the one context where adding them is correct.
-
-Existing `SourceStats` / assertion sites in this file (the literals at
-sources_repo.zig:386-393, 420-427, 483-493 and the zero-default loop at
-sources_repo.zig:365-374) carry the new field with distinct non-zero values
-where their siblings have them, and the round-trip assertions extend to it.
-
-### 3. The manager writes it, and rehydration restores it
-
-`src/filter/manager.zig`. The header already prints
-`# skipped_unsupported {d}` (manager.zig:243) and `SourceStatus.counts` is a
-full `compiler.Counts` (manager.zig:178), so within one process the count
-already reaches the status table. What is missing is the database, which is
-the only thing a restart reads — rehydration never reparses headers.
-
- The fresh-publish path (manager.zig:854-861) passes
-  `.skipped_unsupported_count = compiled.result.counts.skipped_unsupported` to
-  `updateSourceStats`.
- **The checksum-unchanged path (manager.zig:821-836) carries a bug this
-  milestone fixes.** It writes the *stored* `row.skipped_regex_count` back to
-  the database (manager.zig:830) while handing the *fresh*
-  `compiled.result.counts` to the in-memory status (manager.zig:833). The
-  checksum covers the `.list`, `.wild` and `.allow` bodies only, and a skipped
-  line lands in none of them — so a list that changes only its regex or
-  browser-syntax lines keeps its checksum, the running server shows the new
-  number, the database keeps the old one, and the next restart silently reverts
-  what the operator saw. That is milestone 21's column, wrong today.
-
-  Both skip counters take `compiled.result.counts` on this path:
-  `.skipped_regex_count = compiled.result.counts.skipped_regex` and
-  `.skipped_unsupported_count = compiled.result.counts.skipped_unsupported`.
-  ~~`domain_count`, `wildcard_count` and `exception_count` keep reading from
-  `row` — they count written entries, so an unchanged checksum does mean an
-  unchanged value for them.~~ **Corrected post-commit:** that claim was false.
-  The unframed digest could not distinguish an entry in `.list` from the same
-  entry in `.wild`, so an unchanged checksum did not vouch for the entry
-  counts either. The addendum below frames the hash and makes all five stat
-  fields read fresh on this path.
-
-  This needs a test the author has watched fail with the fix reverted: two
-  compiles of bodies whose written entries are identical but whose skipped
-  lines differ, asserting the same checksum, then asserting the database holds
-  the second compile's counts, then rehydrating through `applyLoadOutcomes` to
-  prove the restored status carries them. Report the observed failure output.
- `applyLoadOutcomes` rehydration (manager.zig:1545-1550) adds
-  `.skipped_unsupported = countOf(row.skipped_unsupported_count)` to the
-  `Counts` it rebuilds, so a restarted server reports what the last compile
-  skipped instead of 0.
- Test literals name the field: one `SourceStats` (manager.zig:1928) and two
-  `SourceRow` (manager.zig:2051, 2225). The rehydration test that feeds a row
-  through
-  `applyLoadOutcomes` asserts a non-zero `skipped_unsupported` lands in
-  `status.counts`. The header pin test (manager.zig:2030-2031) already covers
-  the `# skipped_unsupported` line and is extended only if its fixture counts
-  change.
- `rejectedWithoutEntries` (manager.zig:1640-1643) and `failNoValidEntries`
-  (manager.zig:1127-1128) already read the count and are unchanged.
-
-`src/filter/filter_integration_test.zig` names `.skipped_regex_count` in six
-`SourceStats` literals (:826, :858, :1075, :1145, :1257, :2158) — each gains
-the sibling field. The stats round-trip assertion at :915 gains a sibling
-assertion for the new column.
-
-**Do not add an unsupported line to the existing fixture.** The fixture at
-filter_integration_test.zig:112 is hosts-shaped, and `detectFormat`
-(`src/filter/parsers.zig:118`) assigns one format to a whole source. A single
-`##.ad-banner` or `$`-modifier line flips it to ABP, which re-parses every
-existing line: the `*.wild` entry becomes unsupported and address fields
-tokenize as domains (`src/filter/parser_abp.zig:68`). Every expected count in
-that test would move, for a reason unrelated to this milestone.
-
-Add a **separate ABP-format fixture and test** carrying `##.ad-banner` and
-`||ads.example^$third-party` beside two blockable names, and assert
-`skipped_unsupported_count = 2` through the compile-persist-read round trip
-there.
-
-`src/config/reconcile.zig`: the runtime-column preservation test seeds stats
-at reconcile.zig:1096-1110 and asserts survival at reconcile.zig:1173. The
-seed gains `.skipped_unsupported_count` with a distinct value and the
-assertion block gains its expectation. No reconcile logic changes: the engine
-updates declarative columns by name and never touches runtime columns, so the
-new column survives with zero code change — the test is the proof.
-
-### 4. The API speaks it in both shapes
-
-Two shapes carry blocklist counters, and the new count joins both under the
-names its siblings set:
-
- **`Blocklist`** (rows of `GET /api/blocklists`, serialized straight from
-  `SourceRow`): the field arrives automatically once `SourceRow` has it, as
-  `skipped_unsupported_count`. `src/web/openapi.yaml:1877-1895` adds it to
-  `required` and `properties`.
- **`SourceStatus`** (rows of `POST /api/blocklists/update`): `StatusView`
-  (`src/web/handlers/blocklists.zig:52-80`) gains
-  `skipped_unsupported: u32` after `skipped_regex`, mapped from
-  `status.counts.skipped_unsupported` in `from`.
-  `src/web/openapi.yaml:1920-1938` adds it to `required` and `properties`.
-  The handler test literals at blocklists.zig:323 (`SourceStats`) and :386
-  (`counts`) carry the field with non-zero values and the response assertions
-  extend to it.
-
-Contract fallout, all in the same session (ruling 6 explains why):
-
- Regenerate `web/src/lib/contractSamples.gen.ts` with the AGENTS.md command.
- `web/src/lib/types.ts`: `Blocklist` gains
-  `skipped_unsupported_count: number` (types.ts:154-166); `SourceStatus`
-  gains `skipped_unsupported: number` (types.ts:183-195).
- The web test mocks are **not** typed against these interfaces, so `tsc` will
-  not force them. `BLOCKLISTS` in
-  `web/src/features/blocklists/BlocklistsPage.test.tsx` is an inferred object
-  literal handed to a `Record<string, unknown>` (BlocklistsPage.test.tsx:40),
-  and the same untyped-fetch pattern holds in
-  `web/src/features/groups/GroupsPage.test.tsx:16` and
-  `web/src/features/settings/authority.test.tsx:64` — both of which already
-  omit `exception_count` without failing. Updating a mock here is a semantic
-  fixture change, not a typecheck fix, and the implementer must not expect a
-  compiler error to point at them.
-
-  So: the BlocklistsPage mocks (:21, :34 blocklist rows; :104, :155, :168
-  status rows) gain the field because S2's rendering assertions read it. The
-  groups and settings mocks are left alone — they render no counter column,
-  and widening them buys nothing. S1 picks values no other cell in the same
-  table already shows (`3` and `7` are taken), e.g.
-  `skipped_unsupported_count: 21` and `skipped_unsupported: 17`.
-
-### 5. The UI shows it always, in both tables, and says what it means
-
-Both tables gain a `Skipped unsupported` column directly after
-`Skipped regex`, rendered unconditionally:
-
- `web/src/features/blocklists/BlocklistsPage.tsx`: header after :157, cell
-  `{b.skipped_unsupported_count}` after :190, same
-  `shared.td, shared.tabularNums` props as its neighbours.
- `web/src/features/blocklists/SourceStatusSection.tsx`: header after :91,
-  cell `{source.skipped_unsupported}` after :114.
-
-Always-shown is a decision, not a default: every other counter column here is
-unconditional, including `Skipped regex` and `Exceptions`, which are 0 for
-every plain hosts list, and the tutorial already explains those zeros. A
-column that appears only when non-zero would make two lists' tables disagree
-in shape, would hide the header that gives the number its meaning, and would
-special-case exactly the counter this milestone exists to make visible. The
-zero cell is not noise; it states that nothing in this list was classified as
-unsupported — which is narrower than "clean", since `invalid` and `long_lines`
-stay unsurfaced (ruling 7).
-
-The two counters mean different things and the page must say so once. A muted
-paragraph (the existing `styles.empty`-style muted text, matching
-`SourceStatusSection`'s `note` treatment) rendered under the sources table in
-`BlocklistsPage.tsx`, inside the same `else` branch as the table — the note
-describes the two skip columns, so it appears exactly when they do. "Always
-visible" above means unconditional on values, never hidden at 0; it does not
-mean the empty state (`blocklists.length === 0`) carries a paragraph about
-columns that are not on screen. The empty state stays one instruction. Exact
-copy:
-
-> Both “Skipped” columns count lines nxdns read and did not take. Skipped
-> regex lines are patterns nxdns accepts only from you — adopt one you trust
-> as a regex rule. Skipped unsupported lines are syntax nxdns cannot translate
-> into a DNS decision: cosmetic element hiding, browser-only modifiers. A
-> skipped unsupported count that dwarfs the domain count usually means the
-> list is written for a browser extension, and its DNS or hosts variant will
-> block more here.
-
-`BlocklistsPage.test.tsx` asserts: both new headers render, the mock values
-(`21`, and `17` after an update snapshot) render, and the note text is
-present. No threshold logic, no badge, no coloring by magnitude (see
-anti-requirements).
-
-### 6. The docs explain both counters without contradicting what stands
-
- `docs/reference/configuration.md`, section `### blocklist_sources`, after
-  the exceptions paragraph (configuration.md:282-288), a new paragraph:
-
-  > Two counters report what a compile skipped, and they are different facts.
-  > `skipped_regex` counts regex lines: nxdns has a regex engine, but it takes
-  > patterns only from the operator, so a regex line in a downloaded list is
-  > counted, skipped and surfaced — adopt the ones you trust as `regex` rules.
-  > `skipped_unsupported` counts lines nxdns cannot safely translate into a DNS
-  > decision: cosmetic element hiding (`##`, `#@#`, `#?#`), rules carrying a
-  > `$` modifier (except `$important` on an exception line, tolerated above),
-  > scheme anchors, non-anchored `@@` forms — and, in a
-  > `domains`-format list, a line holding more than one field before its
-  > inline comment, which usually means the list is really a hosts file that
-  > was declared as `domains`. Neither is an error, and the two are never one
-  > number. A large `skipped_unsupported` beside a small `domain_count`
-  > usually means the list is written for browser extensions, and its DNS or
-  > hosts variant will block more here. Both appear per source in the
-  > blocklists UI and on `/api/blocklists`.
-
- `docs/tutorial/first-run.md`: the recorded JSON at first-run.md:223 gains
-  `"skipped_unsupported":0` after `"skipped_regex":0` (the endpoint now
-  returns it; the recorded values themselves stand). The paragraph at
-  first-run.md:226-231 becomes four zeros, keeps its `skipped_regex` sentence
-  as written, and **drops the "parts of this list that a hosts file cannot
-  have" framing** — a deliberate small widening ruled during implementation
-  review. The framing was false before this milestone touched it:
-  `parser_hosts.zig` recognizes regex lines (:16), reports a bare sink
-  address as unsupported (:21), and a `*.`-prefixed name compiles to a
-  wildcard in any format. Only `exceptions` is Adblock-Plus-only. The
-  paragraph now presents the zeros as facts about this particular download
-  and says so.
- The `$` modifier is named as skipped **with its one exception**: `$important`
-  on an anchored `@@` exception line is accepted and lands in
-  `exception_count` (`parser_abp.zig`, PLAN §2.2). The configuration.md
-  paragraph above, and the `SourceRow.skipped_unsupported_count` doc comment
-  in `sources_repo.zig` that mirrors it, both carry the qualifier — an
-  unqualified "rules carrying a `$` modifier" contradicts the parser.
- PLAN.md:101 (§3.8) currently reads "regex lines are counted + skipped
-  (counts in metadata → UI)". It becomes: regex lines *and* browser-syntax
-  lines are counted and skipped, both counts in metadata → UI. One sentence;
-  §2.2 (PLAN.md:36-37) already says unsupported forms "stay unsupported and
-  counted" and needs no edit.
- `docs/reference/files-and-directories.md` is untouched: the compiled-file
-  header already carried `# skipped_unsupported` before this milestone and
-  the file table there does not enumerate header lines.
-
-### 7. The other three counters stay out, and the reasons differ per counter
-
-The first draft claimed `invalid`, `long_lines` and `duplicates` were already
-"header-and-error-path only". That is false:
-
- `invalid` reaches the compiled-file header (manager.zig:244) and the
-  `NoValidEntries` text (manager.zig:1127).
- `long_lines` reaches the `NoValidEntries` text only — not the header.
- `duplicates` reaches **nothing**: counted at compile, discarded on every
-  path.
-
-They stay out of scope, and not for one shared reason — which is why the goal
-above says "the silent drop that misleads the operator" rather than "the one
-silent drop left":
-
- `duplicates` hides no failure. A deduplicated name still blocks; the count
-  measures input redundancy, not lost coverage. Discarding it discards a
-  curiosity, so "no silent drops" does not reach it — there is no drop.
- `invalid` and `long_lines` do measure dropped lines, and they remain only
-  partially surfaced. The catastrophic form — a download that is all rejects —
-  already fails loudly (`rejectedWithoutEntries`, state `no_valid_entries`);
-  the residual is a list that loses some lines and still loads, visible in
-  the header file and nowhere the UI reaches. That residual is real, it is
-  recorded here deliberately, and it is not this milestone: the two skip
-  counters name an action the operator can take (adopt the patterns; fetch
-  the DNS variant), while these two say only "the list is malformed", which
-  no column makes more actionable.
-
-The decision is reversible; a later milestone can widen the table. What this
-spec may not do is claim the three are visible when `duplicates` is not.
-
-### 8. Export, import and reconcile change nothing
-
-`nxdns export` / `import` carry configuration; the compile counters are facts
-a running server produces. `model.BlocklistSource` holds only the four
-configuration columns, the insert leaves runtime columns at their defaults
-(sources_repo.zig:1-9, :48-61), and the dump helpers used by the import and
-reconcile suites are `SELECT *` compared dump-to-dump
-(`src/config/import.zig:167-186`, `src/config/reconcile.zig:988`), so no
-golden text names columns and the new column appears in both sides of every
-comparison. Ruling 3's reconcile-test extension is the only touch in
-`src/config/`, plus the model.zig:14 comment from ruling 2.
-
-## Sessions
-
-Two sessions, strictly sequential: S1 then S2. No parallelism — deliberately.
-The regenerated `contractSamples.gen.ts` typechecks only against a `types.ts`
-that already carries the new fields, and the samples are produced by a Zig
-integration run, so the generator and the interface it must satisfy sit on
-opposite sides of the language boundary and cannot land independently. S2's
-rendering assertions then read fields that only exist once S1 has landed both.
-
-(The mocks are *not* part of this argument: they are untyped, so widening
-`types.ts` does not break them. The first draft claimed otherwise.)
-
-### Session S1: column, persistence, API, contract
-
-Owns: `src/storage/config_schema.zig`, `src/storage/migrations.zig` (test
-only), `src/storage/repositories/sources_repo.zig`, `src/filter/manager.zig`,
-`src/filter/filter_integration_test.zig`, `src/config/reconcile.zig` (test
-only), `src/config/model.zig` (comment only),
-`src/web/handlers/blocklists.zig`, `src/web/openapi.yaml`,
-`web/src/lib/types.ts`, `web/src/lib/contractSamples.gen.ts` (regenerated,
-never hand-edited), `web/src/features/blocklists/BlocklistsPage.test.tsx`
-(mock fields only — no rendering assertions),
-`PLAN.md` (the §11.2 line and
-the §3.8 sentence).
-
- S1.1 rulings 1 and 2: the DDL line in both copies, the repo columns, the
-  migrations and repo tests.
- S1.2 ruling 3: both `updateSourceStats` call sites, rehydration, test
-  literals, the reconcile preservation assertion.
- S1.3 ruling 4: `StatusView`, openapi.yaml, sample regeneration, `types.ts`,
-  mock fields.
-
-Acceptance (S1):
- [ ] `zig build test` passes; the migrations baseline test proves
-      `blocklist_sources.skipped_unsupported_count` exists.
- [ ] A compile of the new **ABP-format** fixture carrying `##.ad-banner` and
-      `||ads.example^$third-party` persists `skipped_unsupported_count = 2`
-      through `updateSourceStats` and reads it back through `listSourceRows`.
-      The existing hosts-shaped fixture is unchanged, and every count it
-      already asserts still holds.
- [ ] A second compile whose written entries are byte-identical but whose
-      skipped lines differ produces the same checksum and still updates both
-      skip counters in the database; the test was watched failing with the
-      manager.zig:830 fix reverted, and the failure output is recorded.
- [ ] `applyLoadOutcomes` fed a row with `skipped_unsupported_count = 5` and
-      no live refresh yields `status.counts.skipped_unsupported == 5`.
- [ ] `zig build test -Dintegration` passes, and the regenerated
-      `contractSamples.gen.ts` carries `skipped_unsupported_count` in the
-      Blocklist sample and `skipped_unsupported` in the SourceStatus sample.
- [ ] `cd web && npm run typecheck && npm test` pass with the widened types.
-
-### Session S2: UI and docs (needs S1)
-
-Owns: `web/src/features/blocklists/BlocklistsPage.tsx`,
-`web/src/features/blocklists/SourceStatusSection.tsx`,
-`web/src/features/blocklists/BlocklistsPage.test.tsx` (rendering assertions),
-`docs/reference/configuration.md`, `docs/tutorial/first-run.md`.
-
- S2.1 ruling 5: both columns, the note paragraph, the rendering assertions.
- S2.2 ruling 6: the two doc edits.
-
-Acceptance (S2):
- [ ] `cd web && npm run typecheck && npm test && npm run lint` pass; the new
-      tests assert both `Skipped unsupported` headers, the mock values and the
-      note text.
- [ ] `npm run build` passes (`assert-css-layers.mjs` runs inside it).
- [ ] `docs/tutorial/first-run.md` no longer says "three zeros", its JSON
-      sample carries `skipped_unsupported`, and its `skipped_regex` sentence
-      is unchanged.
-
-### Orchestrator
-
-Verify S1 acceptance before starting S2. After S2, run the full gate set
-(`zig build test`, `zig build test -Dintegration`, `test-aarch64` if qemu is
-present, `cd web && npm test`, `npm run assert-bundled`), then a live smoke
-against a scratch server with two real sources:
-
- `https://easylist.to/easylist/easylist.txt` — a browser-targeted list;
-  expect a `skipped_unsupported` several times its `domains` (do not assert an
-  exact number; assert the ratio and non-zero).
- `https://raw.githubusercontent.com/StevenBlack/hosts/master/hosts` — expect
-  `skipped_unsupported` 0.
-
-Verify the numbers appear in the `POST /api/blocklists/update` response, in
-`GET /api/blocklists`, and in both UI tables. Then restart the server and
-verify the counts survive into the status table without a refresh — that is
-ruling 3's rehydration working against the real database. Record deviations
-in `## Recorded (implementation)`.
-

-## Acceptance (milestone complete)
-
- [ ] All session acceptance boxes above.
- [ ] `config_schema.ddl_v1` and PLAN §11.2 are byte-identical, both carrying
-      the new line; `migrations.steps` still holds exactly one step and
-      `target_version` is still 1.
- [ ] The live smoke: EasyList shows a large `skipped_unsupported` and
-      StevenBlack shows 0, in the API and in both UI tables, and both values
-      survive a server restart.
- [ ] `nxdns export` output is byte-identical before and after a refresh that
-      wrote the new column (runtime columns stay out of exports).
- [ ] The regenerated contract samples typecheck against `web/src/lib/types.ts`
-      — that is what the sample mechanism proves, and it covers server-to-
-      TypeScript agreement only.
- [ ] `src/web/openapi.yaml` is reviewed **by hand** against the two changed
-      response shapes, and the reviewer says so in `## Recorded`. No automated
-      guard covers this: `web_integration_test.zig:2089` checks that routes and
-      methods exist and `:2575` counts operations, but nothing compares a
-      component schema to a real response. An openapi.yaml that omits the new
-      field will pass every gate in this repo.
-
-## Anti-requirements
-
- No migration step, no `ddl_v2`, no runtime schema probing. The baseline is
-  edited in place per §3.7; a pre-edit scratch database is deleted, not
-  reconciled.
- No merging of the two skip counters into one number, anywhere — not in the
-  API, not in a UI total, not in prose. They are different facts.
- No "this list targets browsers" heuristic: no threshold, badge, warning
-  color or ratio computation in the UI. The number plus the note paragraph is
-  the surface; a cutoff would be an invented policy.
- No conditional rendering of the new column. It shows at 0 like every other
-  counter column.
- No change to `nxdns export` / `import` ZON: compile statistics are not
-  configuration.
- No per-line diagnostics, no sample of skipped lines in logs, API or UI —
-  counters and health surfaces, not log spam (AGENTS.md).
- No change to `rejectedWithoutEntries` or `failNoValidEntries` semantics.
- No hand edits to `contractSamples.gen.ts`.
- No new columns beyond the one. See ruling 7 for what that leaves open and
-  why — the reason is a scope decision, not a claim that the other counters
-  are already visible.
-
-## Addendum (post-`1bce81e`): the body checksum is framed
-
-A filtering correctness bug found by the implementation review, predating this
-milestone. Fixed as a follow-up commit; this addendum is its design record —
-the user ruled it a follow-up, not a milestone 25.
-
-### The defect
-
-`bodyChecksum` (manager.zig:1660) and the compiler's incremental hashing
-(compiler.zig:105-108) both digest the unframed concatenation
-`list ++ wild ++ allow`. The compiler strips `*.` from a wildcard candidate
-(compiler.zig:130-133), so upstream `a.example` (list `a.example\n`, wild
-empty) and upstream `*.a.example` (list empty, wild `a.example\n`) hash the
-same bytes. `diskBodiesMatch` (manager.zig:1085) recomputes with the same
-function, so the refresh takes the unchanged-checksum branch and a list that
-switches an exact block to a wildcard block never takes effect. Ruling 3's
-entry-count argument rested on the digest distinguishing bodies; it does not,
-and the strikethrough above records that.
-
-### The fix: a `0x00` separator after each body
-
-The digest becomes `SHA-256(list ‖ 00 ‖ wild ‖ 00 ‖ allow ‖ 00)` — one zero
-byte fed to the hasher **after each of the three bodies**, same order as
-today. Soundness: a compiled body holds only validated name bytes and `\n`;
-`addCandidate` rejects any byte ≥ `0x80` or control byte
-(compiler.zig:151-155), so `0x00` cannot occur in a body and the three
-boundaries are unambiguous. Two distinct `(list, wild, allow)` triples cannot
-produce one digest short of SHA-256 itself.
-
-A separator, not a length prefix, because the compiler hashes while it emits
-and does not know a body's length up front; a trailing byte needs no pre-pass.
-
-Both producers move together or every refresh republishes forever:
-`compiler.compile` feeds the byte after each `emit` call, and
-`manager.bodyChecksum` feeds it after each body slice. Export the separator as
-a `pub const` from `compiler.zig` and have `bodyChecksum` use it — two literal
-`0`s in two files is how the next drift starts.
-
-### Consequences, accepted
-
- Every stored checksum changes once. Zero installs; a development data
-  directory fails its startup checksum verification and the startup refresh
-  pass re-downloads and repairs it (or delete the data directory — the ruling
-  1 stance).
- Checksum compatibility with pre-exception digests — milestone 21 ruling 3's
-  "empty allow body reproduces the old digest" property — is dead, and its
-  rationale comments go with it: `Result.checksum` (compiler.zig:44-53), the
-  `Header` doc and `bodyChecksum` doc (manager.zig:218-225, 1645-1648),
-  `SourceStats.checksum` (sources_repo.zig), and the PLAN §3.8 sentence
-  "keeps the digest it had when only two existed" (PLAN.md:101). All are
-  rewritten to state the framed digest. The body order stays list, wild,
-  allow.
-
-### The branch reads all five fresh
-
-On the checksum-unchanged path, all five stat fields —
-`domain_count`, `wildcard_count`, `exception_count`, `skipped_regex_count`,
-`skipped_unsupported_count` — now read from `compiled.result.counts`;
-`checksum` keeps passing `stored`. With framing, fresh and stored entry counts
-are provably equal, so this is not a correctness requirement — it removes the
-per-field vouching argument from the code entirely, and any future digest
-weakness then degrades to consistent stats rather than a split between
-database and status table.
-
-### Regression tests (each watched failing with the framing reverted)
-
- [ ] Compiler: compiling `a.example` and compiling `*.a.example` produce
-      **different** checksums. This is the collision itself.
- [ ] Manager: publish a source whose body is `a.example`; refresh it with
-      upstream bytes `*.a.example`. Assert the unchanged-checksum branch is
-      **not** taken: the on-disk `.wild` stripped body is `a.example\n`, the
-      `.list` body is empty, and the database row reads `domain_count = 0`,
-      `wildcard_count = 1`.
- [ ] Agreement: `bodyChecksum` over the three stripped on-disk bodies equals
-      `compile`'s reported checksum for a fixture where **all three bodies are
-      non-empty** (extend the existing agreement coverage if it exists; the
-      empty-allow case no longer exercises the third frame).
-
-Report the observed failure output for each, per the ruling 3 convention.

-//!
-//! The contract: any byte string is a legal pattern, so `compile` may reject it
-//! however it likes but must return — never panic, never loop forever, never
-//! read out of bounds. Where it returns a program the target then checks what
-//! the filter is entitled to rely on:
-//!
-//!   - the program obeys ruling 5's limits: it is non-empty, at most
-//!     `max_program_len` instructions, and it came from a pattern of at most
-//!     `max_pattern_len` bytes;
-//!   - `matches` terminates on any input, and the VM's step count never exceeds
-//!     program length × (input length + 1), which is the linearity claim the
-//!     whole design rests on;
-//!   - compile-then-match is deterministic: the same pattern compiled twice
-//!     gives the same program length and the same verdict on the same input,
-//!     and two runs of one program agree step for step.
-//!
-//! `regex.zig` imports only `std`, so this target's module roots directly at
-//! that file — no aggregator needed.
-//!
-//! Runner semantics: under a plain `zig build test` the target runs once per
-//! corpus entry plus once on empty input, which makes the corpus a regression
-//! suite. `zig build test --fuzz=<n>` gives it `n` generated inputs.
