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.

concurrency group in the central job currently collides with the caller
workflow’s group and can cancel the caller. Prefix the central group with a

its predecessor. Non-PR triggers need an explicit collision-safe fallback.
- Sibling-repository review-agent comments use a thin native `issue_comment`
caller pinned to the central `agent-mention-router.yml` commit. The reusable
router must derive that called-workflow SHA from GitHub's OIDC
`job_workflow_ref` claim before checkout; `github.workflow_sha` identifies the
top-level caller during `workflow_call`, and caller-supplied source refs are
not trust evidence. Reusable-workflow `vars` also resolve in caller context;
read the reviewed central allowlist mirror from the verified checkout instead
of trusting a same-named caller variable. Reusable-workflow concurrency must
use the central workflow's literal namespace rather than `github.workflow`,
which resolves to the caller name and can make the called job cancel its own
caller. Keep the scheduled organization sweep only as a bounded
missed-event fallback until every target has a verified native receipt path.
See [`docs/automation/review-agent-comment-invocation.md`](docs/automation/review-agent-comment-invocation.md).
- PR conversation acknowledgement requires job-scoped `pull-requests: write`;
`issues: write` plus `pull-requests: read` can still return HTTP 403 for both
reactions and receipt comments. A missing durable receipt must fail the
router job after dispatch state is preserved; do not emit a warning and mark
the request green.
- Put concurrency at workflow scope when queued jobs must be coalesced before a
runner is admitted. Job-level concurrency cannot relieve a saturated runner
queue because it is evaluated only after job admission.

### Native review-agent comments no longer wait for the organization sweep

- Added a native reusable entry to the central review-agent mention router so
sibling repositories can forward one exact PR comment immediately instead of
waiting for a delayed organization schedule. The router reloads live PR and
comment objects, binds them through the existing exact-name artifact ledger,
and accepts only an exact-SHA central invocation proven by GitHub's OIDC
`job_workflow_ref` claim. Trigger-aware concurrency cancels only the older
invocation for the same workflow, repository, and PR. The organization sweep
remains a bounded missed-event fallback during caller rollout.
- Fixed local PR acknowledgement authority after run `34324306522` dispatched
review work but returned HTTP 403 for both reaction and receipt publication:
the local job now grants job-scoped pull-request write permission, cosmetic
reaction failure no longer emits a warning annotation, and missing receipt
publication fails the run while retaining the durable dispatch claim.
- Isolated reusable-router concurrency from caller context. The central job now
uses its own literal workflow namespace instead of `github.workflow`, so
`cancel-in-progress` cannot cancel the thin caller that invoked it.

### Graphify review graph uses one wheel-validated OpenCode policy

- `agent-mention-router.yml` also exposes the central native comment route as a
reusable workflow. Product repositories own only a thin `issue_comment`
caller pinned to an exact central commit; the reusable job verifies its own
called-workflow SHA from the GitHub OIDC claim before checking out central
code. Its concurrency group uses the central router namespace explicitly;
`github.workflow` is caller context during `workflow_call` and must not make
the reusable job collide with its caller. The scheduled organization sweep
is recovery, not the primary receipt path.
- Mention receipts are required observable evidence. The local router needs
job-scoped `pull-requests: write`; if receipt publication fails after a
dispatch, the run fails closed while the ledger prevents duplicate work on a
retry. Cosmetic reaction failure alone remains non-blocking and emits no
warning annotation.
