fix(tooling): run_lint_gates has refused to run since the cargo-xwin step landed - #11081

… landed
`c038156e98` added a `lint` step that installs cargo-xwin from a pinned,
sha256-verified release asset. Its nine `run` lines are `asset=`, `url=`,
`curl`, `sha256sum --check`, `mkdir`, `tar` and an append to `$GITHUB_PATH` —
none of which `is_gate_command` recognises, correctly, because none of them
asserts anything. The step therefore yielded zero commands and the extractor
failed the whole run:
run_lint_gates: extraction error: step 'Install cargo-xwin for Windows
type-check' has a run: block but yielded zero commands
That takes out the entire local lint replay, not one gate, and
`SKIP_COMPILE_GATES=1` does not help because the step is inside `lint` itself.
The script is what every agent and reviewer is told to run before pushing, so
while it is broken people either skip it or hand-pick gates — the exact failure
it was written to prevent.
A setup step is a real category: it installs a tool the later gates use and
asserts nothing, so there is nothing to replay locally. It is now declared in a
`setup_only` registry next to `ci_only`, and exempted only while it stays a
setup step. Both failure directions are enforced and self-tested: a renamed or
deleted step makes its entry stale and fails, and a setup step that grows a
real gate command fails with "remove its setup_only entry so the gate is
replayed locally" rather than silently hiding that gate.
Verified on a clean checkout of main: before, `--list` errors; after, it
extracts 90 lint commands from 54 run steps plus 6 compile commands, and
`--self-test` passes including the two new fixtures.

It reports errors if that step is renamed or removed, or if it gains a gate command. Self-tests cover both error cases. ChangesLint gate extraction

Test the stale-entry check directly.
The renamed-step fixture passes this assertion because the renamed step yields zero commands. Line 306 skips the stale-entry check whenever a fixture is active. If that check is removed, --self-test still passes, but deleting the setup step can go undetected. Run the stale-entry check for this fixture and assert the “no longer matches the workflow” error.

scripts/run_lint_gates.shhas been refusing to run on main sincec038156e98:That step installs cargo-xwin from a pinned, sha256-verified release asset. Its nine

SKIP_COMPILE_GATES=1doesn't help: the step is insidelintitself. This is the script every agent and reviewer is told to run before pushing, and while it's broken people either skip it or hand-pick gates — the precise failure it exists to prevent (five gates went red on main in one day, 2026-08-17).It's also a good illustration of why "works for me" is worthless on a gate script: it still worked in two worktrees, including mine, because they predate
c038156e98. It only fails on a checkout of current main.The fix
A setup step is a real category — it installs a tool the later gates use and asserts nothing, so there is nothing to replay locally. Rather than loosening
is_gate_command(which would let real gates slip through), such steps are now declared in asetup_onlyregistry beside the existingci_onlyone, and exempted only while they remain setup steps:remove its setup_only entry so the gate is replayed locally, rather than silently hiding that gate.Verification, on a clean checkout of main
--listerrors out. After: 90 lint commands from 54 run steps, plus 6 compile commands.--self-testpasses, and now covers both new failure directions with fixtures (setup-only-renamed,setup-only-grew-a-gate). Each was confirmed to fail before being wired in, so neither passes vacuously.Separately reported and NOT fixed here:
scripts/string_payload_access_inventory.pyexits 1 on main with "baseline is stale",found 0against baselines of 349/28/13. A ratchet whose baseline is stale in the shrinking direction can no longer catch a regression; it needs its own PR from whoever converted those sites.Summary by CodeRabbit
