Copilot, third review — and the second finding is really a verdict on the
approach, so the fix is the approach:
- `SMOKE_BROWSER:` with no value is valid YAML that sets the variable to the
empty string, which `resolveBrowserName` rejects as present-but-empty rather
than treating as unset. The value pattern required \S+, so the guard said
nothing. It is \S* now, with its own message.
- The hand-rolled opener could not see `run: | # explanation` or the flow
mapping `env: { SMOKE_BROWSER: firefox }`. That is the third spelling it has
missed in three rounds, each one a forbidden invocation that would have
passed while test:scripts stayed green — worse than no guard, because it
reports a coverage that is not there. YAML has too many spellings to
recognize by indentation, so extractExecutableRegions now parses with the
`yaml` package. It is already a root dependency, and this file is not in the
published files allowlist, so nothing about the tarball changes.
A parse error now throws rather than yielding no regions: a workflow the guard
cannot read must not pass as a workflow with nothing in it.
Verified by injecting a flow-mapping SMOKE_BROWSER override into the real
main.yml — the suite fails, and goes green again when removed.

Copilot, second review — both findings were real:
- A `${{ … }}` body can itself contain braces, so the `[^}]*\}\}` arm added in
the previous round stopped at the first `}` and missed
`smoke:web:${{ format('{0}', matrix.browser) }}` — the very case it was
added for. It now keys off the `${{` prefix, which nesting cannot defeat.
- Scanning every non-comment line made ordinary metadata a finding:
`name: Explain why smoke:web:firefox stays local` executes nothing and was
reported as an engine invocation, contradicting the header's "what it
forbids, and nothing more". The scan now walks executable positions only —
`run:` scalars (inline and block) and `env:`/`with:` values — via an
exported `extractExecutableRegions`, hand-rolled because `test:scripts` is
dependency-free by design. The narrowing is a stated limit, not a hidden
one: an execution vector outside those three positions is not seen.
Verified by injecting a nested-brace SMOKE_BROWSER expression into the real
main.yml — the suite fails, and goes green again when removed.

Copilot, first review:
- The guard read only literal names, so `npm run smoke:web:${{ matrix.browser }}`
and `npm run local:${{ matrix.task }}` walked past it — the one form in which
a forbidden engine reaches CI without anyone typing its name. It already
refused an expression-valued SMOKE_BROWSER for that exact reason; this applies
the reasoning consistently. Its limit is now stated: a fully opaque
`npm run ${{ matrix.script }}` names no family and is not detectable.
- The module header claimed the gate adds "the non-Chromium engine passes";
it adds Firefox only, and WebKit belongs to neither tier.
- eslint.config.js:33 still said `npm run ci` — the last stale reference.
- AGENTS.md read "everything from `smoke` rightward is `local:gate` only",
which is two claims wrong: smoke and Storybook run in GitHub CI too, and
`pack:verify` is in neither tier.

The root `ci` script was never what runs in GitHub CI, and the name worked
against us three ways: it collides with the built-in `npm ci` (which does
something else entirely and is one keystroke away), it invites the
cross-engine passes into a workflow by looking like the thing a workflow
should call, and it blurs "GitHub CI" and "the local gate" in every doc
that names it.
- Rename `ci` → `local:gate` and `ci:storybook` → `local:storybook`, with
no back-compat alias: `npm run ci` now fails with npm's missing-script
error, which prints the available scripts.
- Add `scripts/lib/workflow-gate.mjs` + its `test:scripts` suite, which
runs over the repo's real `.github/workflows/**` and fails on an
invocation of a `local:*` script, of a non-Chromium engine pass (derived
from SUPPORTED_BROWSERS), or of `smoke:web:engine`, or on `SMOKE_BROWSER`
set to anything but a literal `chromium`. It does not forbid
`npm run smoke`, `smoke:web:chromium` or `smoke:tui` — those belong in CI
and are there today. Comments are not scanned, so the workflow can still
explain itself. This is the durable half; the rest is prose.
- Document the two-tier model once, in the root README ("Two tiers: GitHub
CI and the local gate"), and point the other docs at it rather than
restating the split.
- Sweep the ~40 stale references across README, AGENTS.md,
.github/copilot-instructions.md, the client READMEs, the roadmap doc and
the script headers. AGENTS.md and copilot-instructions.md change
together, per the mirror rule.
No gate changes what it actually runs.
