Drop Deno from the agents and spawn child processes directly

## Summary

Moves `commons/bot-agents` off Deno. The action's TypeScript now runs directly on the job image's Node.js (`node src/<phase>.ts`, using Node's built-in type stripping), with no build step and still no runtime dependency. Repository checks move to Vite+ (`vp check`, `vp test`).

## What changed

- **Runtime.** `action.yml` runs `prepare.ts`, `run.ts`, and `post.ts` with `node` instead of `deno run -A`. `package.json` (`"type": "module"`, `engines.node >=24.2` for `import.meta.main`) is now copied into the root-owned source copy by `scripts/protect-source.sh`.
- **Profiles.** `profiles.yml` → `profiles.json`, with the same content (encrypted values unchanged), parsed with `JSON.parse`. This drops the only runtime dependency (`@std/yaml`).
- **Deno APIs → Node.**
  - `src/command.ts` wraps `child_process.spawn` with the old `Deno.Command` shapes: `output()`/`spawn()`, `clearEnv`, `uid`/`gid`, and Deno's stdio defaults (stdin inherited; stdout/stderr piped for `output()`, inherited for `spawn()`). A signal exit maps to `128 + signo`. Status settles on process exit.
  - `src/errors.ts` maps `NotFound` to `ENOENT`/`ESRCH`.
  - fs, path, stream, and readline calls are mapped one for one. `makeTempFile` becomes an exclusive `wx` 0600 create.
- **Size refactors.** These are needed for Oxlint's default limits. There are no behavior changes and no overrides for source files.
  - `run.ts` is split into `run-context.ts`, `agents.ts`, and `agent-{claude,codex,opencode}.ts`.
  - `post.ts` is split into `post.ts` and `post-artifacts.ts`.
  - `parseCredentials`, `readOutcome`, and `postRuntime` are broken into helpers.
  - Loops that awaited sequentially became recursion or a `reduce` chain, so they stay sequential. `/proc` status reads became `Promise.all`.
  - `src/json.ts` adds type guards in place of `as` casts.
- **Tests.** The 58 `Deno.test` cases were converted to Vitest with the codemod, and its TODOs were finished by hand.
  - Unit tests are `src/*.test.ts`; the repository-level workflow test is `tests/workflow.test.ts`.
  - Root-only tests are now `test.skipIf(!IS_ROOT)`, so they show as skipped instead of silently passing.
  - New `tests/entrypoints.test.ts` runs each phase under real Node to prove its whole import graph loads.
- **Config.** The only config files are `package.json`, `tsconfig.json`, and `vite.config.ts`, plus `package-lock.json`.
  - Lint uses Oxlint correctness/suspicious/pedantic/perf at error, with default limits and type-aware checks.
  - `scripts/project-lint.ts` holds the rule list. It maps Deno's `recommended` rules that fall outside those categories, adds the template's `id-match`, `no-disable-comments`, and `no-non-ts-imports`, and maps Deno's `no-window`/`no-process-global`/`no-node-globals` to `no-restricted-globals` (so `process`/`Buffer` come from `node:` imports).
- **CI.** `.gitea/workflows/check.yml` runs `node --version`, `npm ci`, `npx vp check`, and `npx vp test` in the default runner image.
- **Formatting.** Oxfmt formatting is a separate first commit, so the second commit shows only the semantic diff.
- **AGENTS.md** is updated for the new toolchain.

## Deviations / risks

- **Live `@main` switch.** Six consumer repos use `commons/bot-agents@main`, so merging switches all of them at once. Suggested before merging: tag the current `main` (e.g. `deno-final`) as a rollback target, and canary this branch from one consumer (`uses: …/commons/bot-agents@node-migration`) on a throwaway PR.
- **Node version.** `post.ts` relies on `import.meta.main`, which needs Node ≥ 24.2. DANNYEC's cached `node:24-bookworm` minor is unknown (`forcePull=false`), and the CI job now prints `node --version` to confirm it.
- **Deno stays in the global install.** `deno` remains in the action's global npm install because agents still verify Deno-based consumers (memona, memona-home). Remove it once those repos move.
- **`prefer-readonly-parameter-types` is off.** This pedantic rule is turned off, as in the explicit-types template and the app repos, because Node/web types (`Response`, `Stats`, `RequestInit`) can never satisfy it. `scripts/**` has one narrow override (`no-unsafe-enum-comparison`) for AST node `type` comparisons.
- **Stricter validation of malformed input.** For valid input, behavior is unchanged. A few validations are stricter where the old code would have used a malformed value:
  - Gitea `/user` and comment responses are checked.
  - The runtime manifest and the outcome's profile type are checked against known values.
  - Some type-check errors are now `TypeError` (same messages).
- **@cunarist lint plugins.** "CI fails until @cunarist/eslint-plugin-* are published" does **not** apply here. This repo's Deno setup enabled no plugin, so it depends on none of `@cunarist/eslint-plugin-*`, and CI can pass as is.

## Verification

- `vp check`: formatting, lint (0 warnings), and type check all pass.
- `vp test` as a normal user: 56 passed, 5 root-only skipped.
- `vp test` as root in `node:24-bookworm` (Node v24.22.0, the CI image): all 61 passed, including the UID isolation, process cleanup, and `prepare.ts` cleanup tests.
- End-to-end smoke as root in `node:24-bookworm`, with fake `codex`/`claude`/`npx` binaries and a fake Gitea, through `protect-source.sh` → `prepare.ts` → `run.ts` → `post.ts`:
  - Codex hit "usage limit" and fell through to Claude.
  - Agents ran as UIDs 20000/20001 without the master key.
  - The Codex login was persisted to `/root/.codex/auth.json` (0600).
  - The PR review with an inline comment was posted with the reviewer token.
  - Runtime credentials were removed and the git author was configured.

+description: Frontends build with vp build in Vite app mode, keeping the exact output paths the Rust backend and HTML expect; emptyOutDir false when outDir holds committed files
+---
+
+`deno bundle` was replaced by `vp build` in **Vite app mode** (not
+`build.lib`). Behavior must not change, so the output keeps the file names and
+locations the backend serves and the HTML references.
+
+Typical shape for the Rust-backed frontends (home, eximium, stockvibe,
+memona-home), where `frontend/` builds into `backend/static`:
+
+```ts
+build: {
+  outDir: "../backend/static",
+  emptyOutDir: false, // the folder holds committed files (index.html, ...)
+  rollupOptions: {
+    input: { bundle: "src/index.ts" },
+    output: { entryFileNames: "js/[name].js" }, // -> js/bundle.js
+  },
+},
+```
+
+- **Fixed names, no hashes:** set `entryFileNames` (and `assetFileNames`
+  where assets are emitted) explicitly. Vite's hashed defaults would 404,
+  since Rust and the templates request `js/bundle.js` and `css/theme.css`.
+- **`emptyOutDir: false` whenever `outDir` is outside the Vite root or holds
+  committed files.** Never let it default to true there: it would wipe them.
+- Output stays gitignored, so `.gitignore`, `.containerignore`, and the Rust
+  side need no edits; home's startup check for `js/bundle.js` and
+  `css/theme.css` keeps passing.
+- **CSS is never imported from TS** (no `import "./theme.css"`); the HTML
+  links the stylesheet. How the CSS file is produced is per repo; read the
+  repo's `vite.config.ts` before changing it.
+- Copy whole `js/` and `css/` directories in Containerfiles, not single files,
+  so code-split chunks ship too ([[app-containers-and-ci]]).
+- Where a repo serves an `index.html` entry (brain's dashboard), use plain app
+  mode with `index.html` as input, `base` set to the mount path, and `outDir:
+  "dist"` with the default `emptyOutDir`.
+- `vp dev` must work too, and the decorators plugin must cover build, dev, and
+  test ([[decorators-standard-accessor]]).
+
+Check the repo's own migration PR for its final values before editing; these
+are the conventions it followed, not a config to paste.

+
+`src/child.ts` holds what the call sites share:
+
+- **`exitCode(child)`**: call it right after `spawn`. It settles on `exit`

+description: Every repo moved from Deno to Node + Vite+ in Oct 2026 because Cloudflare bought Deno; nothing goes back to Deno
+---
+
+On 2026-10-12 the user moved every project from Deno to Node.js + Vite+
+(`vp`). Cloudflare bought Deno on 2026-10-09; the runtime gets roughly 12
+months of maintenance and Deno Deploy shuts down around April 2027. None of the
+repos used Deploy or KV, so the move is about the toolchain, not hosting.
+
+Do not reintroduce `deno.json`, `deno.lock`, `Deno.*` APIs, `jsr:` or `npm:`
+specifiers, `mod.ts` entries, or `deno task` anywhere, docs and scripts
+included.
+
+## Order the migration followed
+
+1. The custom Deno lint plugins were ported to npm first, as
+   `@cunarist/eslint-plugin-explicit-types`, `-import-check`, and `-lit`.
+   `cunarist/eslint-plugin-explicit-types` is the template every other repo
+   copies (config shape, `scripts/project-lint.ts`, AGENTS.md, notes).
+2. Then `commons/bot-agents` (six repos use it as an action), then the apps:
+   home, eximium, stockvibe, brain, memona, memona-home.
+3. deno-practice, interview-practice, web-landing, and vemium were left out
+   (archivable). Old `cunarist/deno-*` repos are archived one at a time, and
+   only after their `eslint-plugin-*` replacement is published to npm.
+
+## What "migrated" means
+
+- Same behavior. A migration PR changes tooling, not features.
+- Lint coverage is at least what Deno enforced: [[lint-parity-never-shrinks]].
+- Only three config files and only `.ts`: [[toolchain-node-vite-plus]],
+  [[ts-only-files-and-imports]].
+- Deno.test suites became Vitest: [[tests-layout-vitest]].
+
+The custom plugins' Deno names map like this:
+
+| Deno                                            | npm                                      |
+| ----------------------------------------------- | ---------------------------------------- |
+| `jsr:@cunarist/deno-lint-plugin-explicit-types` | `@cunarist/eslint-plugin-explicit-types` |
+| `jsr:@cunarist/deno-import-check` (`./lint`)    | `@cunarist/eslint-plugin-import-check`   |
+| `jsr:@cunarist/deno-lint-plugin-lit`            | `@cunarist/eslint-plugin-lit`            |
+| `scripts/deno-lint-plugin.ts` (per app)         | `scripts/project-lint.ts` (per app)      |
+
+Until those packages are on npm, a repo that depends on them fails `npm ci` in
+CI; that is expected and stated in the PR, never worked around by committing
+tarballs or `file:` dependencies.

+---
+
+memona's way of declaring icons is the standard (2026-10-14). An icon is a
+`.ts` module that exports a Lit `TemplateResult` holding the inline SVG:
+
+```ts
+// src/icons/lock.ts
+import { html, type TemplateResult } from "lit";
+
+/** Font Awesome Free's solid `lock`, as its SVG source. */
+export const lockIcon: TemplateResult = html`<svg

+  viewBox="0 0 384 512"
+>
+  <path fill="currentColor" d="M128 96l0 64 ..." />
+</svg>`;
+```
+
+```ts
+// usage
+import { lockIcon } from "#icons";
+render() { return html`<span class="icon">${lockIcon}</span>`; }
+```
+
+- One icon per file, camelCase name with an `Icon` suffix, a doc comment
+  saying what it depicts, exported through `src/icons/index.ts`.
+- Use `fill="currentColor"` so CSS controls the colour.
+- Keep a third-party licence comment that the SVG source carries (Font
+  Awesome Free's `<!--! ... -->` notice) inside the template.
+
+**Replaced pattern:** eximium, stockvibe, and memona-home imported Font
+Awesome `.svg` files as text in `icons.ts`:
+
+```ts
+import lock from "@fortawesome/fontawesome-free/svgs/solid/lock.svg" with { type: "text" }; // no
+```
+
+That breaks [[ts-only-files-and-imports]] (non-`.ts` import plus import
+attributes) and was converted to memona's style during the frontend
+migration. Before writing new icon code in any repo, read how that repo (or
+memona) already declares icons and match it.

+- Every directory's entry file is `index.ts`, never `mod.ts` (decided
+  2026-10-12; import-check's `enforce-mod-file` now requires `index.ts`).
+- A directory used from outside exposes its API through its `index.ts`

+- **Categories:** `correctness`, `suspicious`, `pedantic`, `perf` at `error`.

+Oxlint (1.87) has no `noInlineConfig` and no `eslint-comments` rules, and

+2. `unicorn/no-abusive-eslint-disable` fails a directive that names no rule,

+
+Every form was probed and fails `vp check`.
+
+A rule that fires on legitimate code is a rule problem: change the rule or its
+options in `configs.project` with the user's agreement, not the call site.
+Known example: rule records are `Map`s keyed by id rather than object

+lit-analyzer is built on TypeScript's JavaScript compiler API and is run

+
+## Key order (2026-10-14)
+
+Metadata first, then `scripts`, `exports`, `imports`, `devDependencies`,
+`dependencies`. Oxfmt would re-sort the file, so `vite.config.ts` sets
+`fmt: { sortPackageJson: false }`; keep it, and keep the order by hand.
+
+```jsonc
+{
+  "name": "@cunarist/eslint-plugin-x",
+  "version": "0.1.0",
+  "description": "...",
+  "keywords": ["eslint", "eslint-plugin", "eslintplugin", "oxlint"],

+  "imports": { "#helpers": "./src/helpers/index.ts" },
+  "devDependencies": { "vite-plus": "^1.1.0" },
+  "dependencies": {},
+}
+```
+
+The `imports` key order can carry meaning: import-check's
+`enforce-layer-order` reads it as the layer order. Never reorder it casually.
+
+## Fields
+
+- **Standard fields only.** `engines` has only `node` (never `engines.bun`).
+  A tool-owned key (`eslint-doc-generator`) is allowed only because the tool
+  reads nothing else and no other config file is allowed.
+- **No `packageManager`.** npm is detected from `package-lock.json`.
+- **No `peerDependencies`, ever** (user preference, 2026-10-14). If something
+  is needed at runtime, it goes in `dependencies`.
+- **`dependencies`** = what runs or is type-referenced at runtime by consumers
+  (the lit plugin ships `parse5`, `oxc-parser`, `oxc-resolver`, and
+  `@eslint/core` for its public types; they stay external, never bundled).
+- **`devDependencies`** = everything else: `vite-plus`, `eslint`,
+  `@typescript-eslint/parser`, `eslint-doc-generator`, `esbuild`,
+  `typescript-6`, `@types/node`. ESLint is a devDependency only; plugins need
+  nothing from it at runtime.
+
+Refresh the lockfile with `npm install` (or `npm install
+--package-lock-only` for a version bump) and commit it with the change.

+description: scripts/project-lint.ts is the repo-local plugin "project" holding the repo's rule list (typed DummyRuleMap) and repo-only rules; never published, no tests
+---
+
+Every repo has `scripts/project-lint.ts`, copied from
+`cunarist/eslint-plugin-explicit-types` and extended. It is a repo-local
+Oxlint plugin with `meta.name` `"project"`, loaded through `jsPlugins` in
+`vite.config.ts`. It holds:
+
+- **`configs.project.rules`**: the repo's whole rule list beyond the published
+  plugin configs: Deno parity rules, extras, per-rule options, and opt-outs,
+  built-in Oxlint ids included (`curly`, `id-match`, `import/no-cycle`, ...).
+- **Custom rules**, enabled as `project/<rule>`. Every repo has
+  `no-disable-comments` and `no-non-ts-imports`. Apps also port the rules of
+  their old `scripts/deno-lint-plugin.ts` here under the same names and
+  behavior (`no-self-sync`, `app-module-conventions`, `restricted-types`, ...).
+
+Rules and plugin stay in this one file; don't add `scripts/rules/`.
+
+```ts
+import type { DummyRuleMap } from "vite-plus/lint";
+
+const rules: DummyRuleMap = {
+  "id-match": ["error", "^_*[^_]*_*$|^[^a-z]*$", {/* ... */}],
+  curly: "error",
+  "project/no-disable-comments": "error",
+};
+
+const plugin = {
+  meta: { name: "project" },
+  rules: { "no-disable-comments": noDisableCommentsRule /* ... */ },
+  configs: { project: { rules } },
+};
+export default plugin;
+```
+
+## Why `DummyRuleMap` and an unannotated plugin (decided 2026-10-15)
+
+- `DummyRuleMap` (re-exported by `vite-plus/lint`) is Oxlint's type for
+  `OxlintConfig.rules`. Despite the name it lists every built-in rule with its
+  options, so a typo in a rule id or option is a type error, not just a CI
+  failure. Without it, TypeScript widens `"error"` to `string`; `as const`
+  doesn't help because Oxlint wants mutable tuples.
+- `@eslint/core`'s `Plugin` is too loose to read back: `configs` is optional,
+  any key may be missing, and a config may be an array, so
+  `projectLint.configs.project.rules` fails in `vite.config.ts` (and `!` is
+  banned). Optional chaining still leaves the array case.
+- Oxlint's own `Plugin` type (`vite-plus/lint/plugins`) has no `configs`.
+- Two hand-written interfaces worked but were dropped as noise; a plain
+  config object was rejected because custom rules need the plugin form anyway
+  and every repo should look the same.
+
+`scripts/` is tooling, not production code: never packed or published, and
+no tests. Narrow `overrides` for `scripts/**` are allowed when a script truly
+needs one (e.g. `no-console`); see [[lint-overrides-policy]].

+description: Packages publish only from CI when a GitHub release vX.Y.Z is published, via npm trusted publishing; never npm publish by hand; notes live only on the release page
+---
+
+Standing convention (2026-10-12), applied to every package:
+
+- **Only CI publishes.** Publishing a GitHub release `vX.Y.Z` triggers
+  `.github/workflows/publish.yml`. Never run `npm publish` locally and never
+  push a bare `v*` tag. Use the `release` skill, and only when the user asked
+  for a release.
+- **The workflow** checks that the tag equals `v` + `package.json` `version`,
+  runs the full CI as a reusable workflow (every Node version in the matrix),
+  then `vp pack` and `npm publish --access public --provenance`. A release
+  marked pre-release publishes under the `next` dist-tag, others `latest`.
+  It runs on Node 24 (npm 11, which trusted publishing needs) with no cache.
+- **Auth is npm trusted publishing** (OIDC, `id-token: write`), which also
+  attaches provenance. npm only allows a trusted publisher on a package that
+  already exists, so the very first release bootstraps with a short-lived
+  token in the `NPM_TOKEN` repo secret (the workflow uses it only when set).
+  Afterwards the user configures the trusted publisher for `publish.yml`,
+  deletes the secret, and sets the package to disallow tokens.
+- **Release notes live only on the GitHub release page**
+  (`--generate-notes`, edited there). There is no `CHANGELOG.md`; never add
+  one.
+- **The version lives in two places in plugin packages:** `package.json` and
+  `meta.version` in `src/index.ts`; `tests/package-meta.test.ts` fails if they
+  differ.
+- **Before 1.0**, a change that breaks users (renamed rule id, a rule that
+  fires on more code, removed behavior) is a minor bump.
+- **Before a release**, pack the package and lint a known-bad and a known-good
+  file from separate consumer projects, once through `vp lint` with
+  `jsPlugins` and once through ESLint 9 with the configs. On the lit plugin
+  this caught two bugs that 313 unit tests missed.
+
+The cunarist lint plugins (explicit-types, import-check, lit) are published
+together, with a token the user provides; the old `deno-*` repos are archived
+only after that, one at a time.

+Decided 2026-10-14 for all repos.
+
+- **Runner:** Vitest through `vp test`. Import test APIs from
+  `vite-plus/test` (`describe`, `expect`, `it`).
+- **Unit tests** sit next to the code: `src/foo/bar.ts` is tested in
+  `src/foo/bar.test.ts`. Vitest's default include finds them; no `test`
+  config needed. Packages publish only `dist/`, so colocated tests cost nothing
+  in the tarball.
+- **Regression and integration tests** live in the top-level `tests/` folder
+  and use only the public entry point (an alias like `#plugin`), never
+  internals. `vp test tests` runs just these.
+- **No in-source tests** (`import.meta.vitest`).
+- **`scripts/` gets no tests** (2026-10-15): it is repo tooling, not
+  production code (`project-lint.ts`, `decorators.ts`, `lit-check.ts`,

+- Test files follow every lint rule; no relaxed overrides for tests.
+
+## Migrating Deno tests
+
+`Deno.test` suites were converted by a codemod

+  `node:child_process`;
+- `t.step` → nested `describe`/`it`;
+- sanitizer options, which Vitest doesn't have.
+
+A migration PR must keep every test case; a dropped case is lost coverage.
+Tests must pass locally before any push.

+description: Node.js 22+ with Vite+ (vp) and npm; only package.json, tsconfig.json, vite.config.ts plus a committed package-lock.json
+---
+
+## The stack
+
+- **Runtime:** Node.js 22 or newer. `engines` is `{ "node": ">=22" }` and
+  nothing else. Containers and the publish job use Node 24 (LTS); a repo may
+  need more where a feature demands it (bot-agents uses Node 24.2+).
+- **Bun is not supported** (dropped 2026-10-15). No Bun CI legs, docs, or
+  runtime branches. Oxlint's `RuleTester` refuses to run under Bun anyway, and
+  `vp` brings its own Node, the way uv brings its own Python.
+- **Toolchain:** Vite+ (`vite-plus` devDependency, command `vp`): Vite,
+  Vitest, Oxlint, Oxfmt, type checking, tsdown.
+- **Package manager:** npm everywhere. `package-lock.json` is committed in
+  apps _and_ libraries (user agreed 2026-10-14: `npm ci` needs it). There is no
+  `packageManager` field; Vite+ detects npm from the lockfile.
+
+## Config files
+
+Exactly three, plus the lockfile: `package.json`, `tsconfig.json`,
+`vite.config.ts`. No `.oxlintrc.json`, `.prettierrc`, `eslint.config.*`,
+`vitest.config.*`, `.npmrc`, or `tsdown.config.*`. Tool options go into
+`vite.config.ts` keys (`lint`, `fmt`, `test`, `pack`) or, when a tool only
+reads `package.json` (eslint-doc-generator), into a `package.json` key.
+The target is a short `vite.config.ts`, around 30 lines (not strict).
+
+## Commands
+
+| Command                  | Does                                                       |
+| ------------------------ | ---------------------------------------------------------- |
+| `vp check`               | format check, Oxlint (type-aware), and type check together |
+| `vp check --fix`         | the same, applying formatting and safe fixes               |
+| `vp test`                | Vitest; `vp test tests` runs only the top-level `tests/`   |
+| `vp build`               | Vite production build (apps)                               |
+| `vp dev`                 | Vite dev server (apps)                                     |

+| `npm ci` / `npm install` | install; never another package manager                     |
+
+`vp check`, `vp test`, and the build (`vp build` or `vp pack`) must all pass
+before any push. CI installs the toolchain with `voidzero-dev/setup-vp`.
+
+## Gotchas found during the migration
+
+- `vp check` does **not** report `isolatedDeclarations` errors (TS9010); only
+  `vp pack` does, so packages run `vp pack` in CI on every PR.
+- Oxfmt sorts `package.json` keys by default, which destroys the required key
+  order. Set `fmt: { sortPackageJson: false }` ([[package-json-shape]]).
+- Oxlint and Oxfmt skip what `.gitignore` lists; that is the only reason
+  `dist/` and `node_modules/` are not linted. Keep build output gitignored.
+- Vite+ bundles `vite.config.ts` itself and resolves `#` imports in it.
+- Oxlint loads a `.ts` plugin file directly on Node 24 (`jsPlugins`), so
+  repo-local lint plugins need no build step.

+  fewer custom types when the result is equivalent.
+
+## Conventions over invention
+
+- Follow ESLint's and the wider ecosystem's conventions (typescript-eslint,

+  flat configs at `plugin.configs`, `meta.docs.url`, `index.ts` entries.

+At the start of every new session, run `damem recall` in the terminal and treat
+its output as the context for this repository. If the `damem` command is not
+found, read [INSTALL.md](https://github.com/cunarist/damem/blob/main/INSTALL.md)
+and follow it before reasoning or responding.
+
+# Pull requests
+
+Land every change through a pull request. Immediately after creating one,
+comment `@bot` to request an AI-bot review. Wait for green CI and the bot's
+approval on the current head before merging. Never merge without the user's
+explicit permission.
+
+# Runtime and checks
+
+The action's TypeScript runs directly on the job image's Node.js (24.2 or
+newer), which strips the types itself: there is no build step and no runtime
+dependency. Keep the sources to erasable syntax and `.ts` imports, which
+`tsconfig.json` enforces. Checks use Vite+: `vp check` formats, lints, and
+type-checks, and `vp test` runs Vitest. Unit tests sit next to the code as
+`src/*.test.ts`; repository-level tests live in `tests/`.
+
+The only config files are `package.json`, `tsconfig.json`, and
+`vite.config.ts`, plus `package-lock.json`. Repo-local lint rules and the rule
+list live in `scripts/project-lint.ts`. Lint disable comments are not allowed;
+fix the source instead.
+
+The composite action uses npm only to install the externally distributed
+Claude Code, Codex, and OpenCode command-line tools; do not treat those
+vendor executables as repository TypeScript dependencies.
