중앙 잡의 동시성 그룹을 호출자 그룹과 분리하십시오.
문서의 호출자는 ${{ github.workflow }}-${{ github.repository }}-${{ github.event.issue.number }}를 사용하고, PR 번호를 inputs.pull_request_number로 전달합니다. 재사용 워크플로의 github.workflow와 github.repository는 호출자 컨텍스트를 사용합니다. 따라서 두 그룹은 동일합니다. 두 그룹의 cancel-in-progress: true 설정은 중앙 잡이 실행 중인 호출자 워크플로를 취소하게 할 수 있습니다.
중앙 그룹을 central-${{ github.workflow }}-${{ github.repository }}-${{ inputs.pull_request_number }}처럼 변경하십시오. 중앙 잡의 cancel-in-progress: true는 동일 PR 요청을 병합하기 위해 유지하십시오. 테스트의 단언과 문서의 호출자·중앙 잡 그룹 설명도 갱신하십시오.

Protected-default bootstrap evidenceExact-head mention request run 34325587103 reached terminal
Therefore this run is not clean receipt evidence and does not validate the PR-head permission/fail-closed repair. The branch fixture tests remain the available pre-merge proof; the first protected-default mention after protected integration must produce a durable receipt and no warning-class output. |

Noema LLM review
The PR adds a native reusable workflow_call entry to agent-mention-router.yml so sibling repositories can forward exact PR comments without waiting for the organization sweep. The prior thread concern about concurrency group collision is addressed: the central job uses a literal review-agent-mention-router-central namespace instead of github.workflow, so cancel-in-progress cannot cancel the invoking caller. Receipt-publication authority is corrected with job-scoped pull-requests: write and fails closed after dispatch. OIDC job_workflow_ref proof, exact-SHA checkout verification, non-symlink allowlist mirror check, and caller-context vars avoidance are present and tested. No blocking regression was confirmed; probes for caller cancellation and silent receipt-swallowing were falsified. Non-blocking review notes remain about concurrency scoping and minor script robustness, but they do not require changes.
Reviewed changed lines
.github/workflows/agent-mention-router.yml:83 (RIGHT): The concurrency group uses review-agent-mention-router-central-${{ github.repository }}-${{ inputs.pull_request_number }} without github.workflow, avoiding the caller-cancellation regression.scripts/ci/agent_mention_router.py:700 (RIGHT): Receipt-comment failure now raises RuntimeError instead of emitting a warning, failing the run after dispatch state is preserved..github/workflows/agent-mention-router.yml:118 (RIGHT): Exact-SHA checkout verification checks git rev-parse equality and non-symlink allowlist mirror presence. Working-directory drift is not currently a confirmed failure.scripts/ci/exchange_opencode_app_token.sh:1 (RIGHT): Token exchange script is shared between native and sweep routes; native path fails closed later if the token is empty. Token-format validation is a minor robustness note.
Adversarial validation
.github/workflows/agent-mention-router.yml:83 (RIGHT)falsified: The reusable central job's concurrency group references github.workflow, causing cancel-in-progress to cancel the invoking caller workflow. — The group expression is review-agent-mention-router-central-${{ github.repository }}-${{ inputs.pull_request_number }} with no github.workflow token in the changed lines.scripts/ci/agent_mention_router.py:700 (RIGHT)falsified: Receipt-comment publication failure is swallowed as a warning, allowing a missing durable receipt to hide behind a green run. — The new code raises RuntimeError('Agent mention receipt publication did not complete; ...') from exc and the focused test asserts pytest.raises with one preserved dispatch mutation.- Residual risk: Concurrency group is keyed on caller github.repository and caller-supplied inputs.pull_request_number, so a misconfigured caller within the same repository could collide with and cancel another own-native invocation for the same PR; cross-repository and cross-PR collisions are bounded by the key scoping. Token-format validation in the exchange script is a minor robustness gap. Neither issue is confirmed as a blocking regression.
Findings
- [low] scripts/ci/exchange_opencode_app_token.sh:1 (RIGHT): The shared token exchange script treats missing OIDC environment or exchange failures as available=false with exit 0. The native route fails closed downstream when OPENCODE_APP_TOKEN is empty, but a direct future reuse of this script without checking available output could silently continue with no credential.
- [low] scripts/ci/exchange_opencode_app_token.sh:48 (RIGHT): The app token is written to GITHUB_ENV without format or length validation; malformed responses would only surface later as API errors. This is a robustness rather than security issue because the source is the trusted OpenCode exchange endpoint.
