The backend: claude gap is the substantive one: lopu-agent/action.yml gates the ordered-bundle
fetch on inputs.backend == 'claude', so flipping the probe to backend: codex would leave every
advisory green while the live vault check the job is named for silently stopped running — the
exemption would keep paying out for a probe that no longer probes.
The step-window difference matters too. #575 finds the probe step by scanning forward to the next
- name:; #584's yamlStepAt derives both bounds from the matched line's own indentation, which is
what survives a - bullet inside a prompt block scalar, a blank line or # note inside the probe,
and a composite action's shallower step depth. #584 ships fixtures for all of those.
Changes made
None. The code here is not wrong, and adding the missing backend: claude assertion would only
deepen a collision that ends with this branch being closed.
Recommendation
Land #584; close this PR as superseded. If you prefer #575's shape instead, it needs the
backend: claude assertion added before merge, and #584 then needs closing — but #584 also carries
the fixtures and the control-plane/ widening, so the exchange is lossy in that direction.

So this PR is not half of a pair — it is the whole fix for both, and it is the only open candidate that touches either. My earlier comment here said "neither PR greens the base alone — they're independent halves"; that is wrong against today's base. #573 is a genuinely good change, but it repairs a different class of bug (captured-stdout annotations) and greens nothing on its own.

🌸 Lopu — correct, but duplicated by #584; recommending this one be closedTo be clear up front: the code here is not wrong. All 13 control-plane contracts pass on this head, and both fixes are sound —
The problem is that #584 fixes the same two advisories in the same two files, and the two cannot coexist. Simulated merge from The conflict is exactly the two duplicated files, and it is symmetric — whichever of the pair lands second conflicts. Recommendation: land #584, close this. Not because #584 is better line for line, but because it is already rebased onto the current tip (0 behind, vs 4 here) and it carries two things this PR does not: it widens the enforcement I checked whether anything would be lost by closing: the one idea unique in spirit here is the separate I'm raising this rather than closing the PR myself — that's the owner's call. |

It covers everything here and adds two things this branch doesn't:

That reasoning is right, but the conclusion drawn is one level too coarse. Job keying rules out adopting the id; it does not rule out standing next to the probe. Add a second, secret-bearing worker to that job — which is an ordinary thing to want, since the job already holds the vault credentials: - name: Second Lopu worker in the vault job

Neither failure is an outage, a stale result, or a cancellation, and neither is
caused by PR #573. Both were introduced today by commits already merged into
github-actions, and both are contract staleness: in each case the workflowchange was correct and the contract simply was not updated with it. So the fix
belongs in the controller, not on a PR branch.
Root cause 1 —
resolve-pr-conflicts-routing-contract.mjsBisected to
51813961"fix(ci): verify Claude vault credentials live"(2026-09-01 15:07 +1000):
That commit added the credential-vault verification probe (
id: live_probe,"Verify the credential waterfall with one live Claude turn"). The probe passes
thingtime-ci-router-secretand no credential slots at all — not theprimaries, not the fallbacks. That is deliberate and correct: the step exists to
prove the Thingtime waterfall itself still authenticates, so giving it
GitHub-secret fallbacks would let a broken vault produce a green probe.
The contract's rule — "every Lopu call receives the secondary API-key slot" —
was written for the secret-bearing resolver workers and over-generalized to a
step that must not have those slots. The workflow is right; the contract is
wrong.
Change 1
.github/scripts/resolve-pr-conflicts-routing-contract.mjsonly. Exempt thevault probe from the fallback rule, and pin the property that earns the
exemption so a real worker cannot inherit it by simply omitting its
credentials:
uses:line preceded byid: live_probe.anthropic-api-key,claude-code-oauth-token,-preferred, or-fallbackinput.The exemption is therefore self-policing: the moment the probe is handed any
credential slot, it stops being a vault probe and the contract fails again.
Root cause 2 —
promotion-worker-routing-contract.mjsBisected to
d5e984a0"fix(ci): reconcile already-merged Feature Stacks"(2026-09-01 22:53 +1000):
That commit added a fourth guard to
feature_stack_merge:The contract matched the condition as one fixed sequence with
\s*between thetwo
result == 'success'conjuncts, so an interleaved guard could not match.The property under test —
!cancelled()plus an explicitresult == 'success'per direct need, instead of GitHub's default
success(), which is what keepsthe worker running when an indirect dependency is legitimately skipped — is
still fully satisfied.
Change 2
.github/scripts/promotion-worker-routing-contract.mjsonly. Extract thefeature_stack_mergeif:block and assert each required conjunct on its ownanchored line instead of as one rigid sequence. An added guard now extends the
condition without silently retiring the contract, while removing any required
gate still fails.
No workflow, job, permission, trigger, routing, or credential behaviour is
changed by either fix. Both changes are test-side only.
Validation
All commands run in
$GITHUB_WORKSPACE/trusted(detached atac680d64,github-actions).Bisection, shown above, establishing each breaking commit and that each

Both contracts now pass:
Full advisory suite — 11/11 green (was 9/11):
Negative tests — each contract still catches the regression it exists for.

a secret-bearing worker past the fallback rule.
