Plain `env` preserves the parent environment, and on the runner every step
arrives with GITHUB_API_URL set — the premise of the fix under test — so the
unset-refusal case inherited it and never exercised the refusal. It passed
only in a dev shell that lacks the variable: the environment distance
UPSTREAM-SYNC.md step 7 warns about, in the test written the same day
(@kimi-reviewer-andresmgsl, run 468).

Three corrections from @codex-reviewer-andresmgsl's review of 935a813.
1. `api="${GITHUB_API_URL:-https://api.github.com}"` guessed GitHub when the
variable was absent — driven with a recording curl, it reported success
after POSTing to api.github.com from this forge. That is the "Never
'probably github'" rule, and the same unset-environment refusal #201 just
established for docs-sync. It now refuses before any request, and the test
asserts zero calls were made: refusing after a POST is not refusing.
2. The "never silenced with || true" invariant was still asserted by grepping
the gh line this port removed, so it passed on any REST implementation
including one that swallows a failed POST. It is rebound behaviourally: a
curl that dies at the transport must fail the step. Doing that revealed the
step failed with a bare exit 7 and no sentence, so it now names the failure
— owning the diagnostic is the whole point of the surrounding code.
3. docs/CONSUMERS.md and both caller comments still described `gh workflow
run` as the mechanism. They describe the REST dispatch now, and the manual
bootstrap command carries a forge-neutral curl form beside the gh one: a
cross-forge runbook that sends this forge to a missing binary is wrong even
where the prose around it is right.
Refs #205
`.github/workflows/labels.yml` dispatched the sweep with `gh workflow run`,
the eighth runtime gh call site the 0.6.0 merge reintroduced and the only one
!204 did not port. On this forge the runner carries neither gh nor a GitHub
API, so the step refused and the entire event-driven reconcile path ended
there — every transition waiting up to an hour for the scheduled sweep.
The workflow-dispatch endpoint has the SAME shape on both forges:
POST {api}/repos/{owner}/{repo}/actions/workflows/{file}/dispatches
{"ref": "<branch>", "inputs": {...}} -> 204, empty body
so the step no longer decides a forge at all. The CEREMONY_FORGE_CLIENT=gh
declaration and both inline refusals are removed rather than ported, and
test/no-runtime-gh.test.sh now asserts their ABSENCE — an opt-out with no gh
behind it is a standing permission slip.
The ref is supplied explicitly and taken from the repository, never from
GITHUB_REF_NAME: on a pull_request_target run that is `<n>/merge`, which is
not a branch. A non-204 still fails the job, keeping the misconfiguration
alarm the trigger exists to be, and the diagnostic explains Forgejo's empty
500 rather than passing a bare status to a reader who will go looking for an
outage that is not there.
test/labels-dispatch.test.sh extracts the shipped step and executes it against
a recording stub, asserting the method, endpoint, ref and inputs actually
sent. Dropping the inputs or ignoring a non-204 both red the suite.
