Exact-head independent review for ed8ab26b53792386e4578fcfbd3bdf1632cff54c: no substantive finding.
I reviewed the seven-file effective delta and exercised the identity design against hosted GitHub evidence rather than relying on the nominal bot statuses (Devin says its full review was skipped; CodeRabbit says it was rate-limited). In particular, native run 34057701346 / job 101557511207 confirms the proposed bindings: pull_request_target, workflow/path Strix Security Scan / .github/workflows/strix.yml, job/check name strix, GitHub Actions publisher, shared check-suite ID, exactly one PR association with base/head repositories and exact head SHA, and exact protected run-name.
The same job's terminal provider HTTP 500 is a legitimate failure rerun candidate. Immediately before a manual retry I re-read PR #1991 and protected main; both still matched the recorded base/head, and GitHub accepted attempt 2. Repository-dispatch runs remain outside this rerun path unless they carry authenticated target provenance, which is the required fail-closed boundary.
Checks on this head remain queued, so this COMMENT is semantic review evidence only, not an approval or a claim that required checks are complete.

Selective post-#1929 recovery receipt for unchanged exact head
No source/ref, Ready state, or merge setting changed. This receipt is not CodeQL GREEN, approval, or merge authority; ordinary integration remains gated on fresh exact-head terminal evidence. |

Exact-head lifecycle finding for ed8ab26b53792386e4578fcfbd3bdf1632cff54c from live central evidence; this is not a timeout/age inference.
Draft→Ready on unchanged heads caused GitHub concurrency to cancel the only active scanner jobs:
- #1706: Strix run 34068478185 / job 101587206691 was executing
Run Strix (quick)and cancelled at 2026-09-07T02:44:55Z. Ready replacement 34077290787 is only queued. - #1150: Strix run 34067942252 / job 101591530472 was executing
Run Strix (quick)and cancelled at 2026-09-07T02:45:03Z. Ready replacement 34077297932 is only queued.
Both annotations say a higher-priority waiting request in the same PR-stable concurrency group cancelled the run. PR repository/head identity remained unchanged. Neither old publisher ran, so no terminal authoritative Strix verdict exists; a prospective queued replacement is not evidence.
This exposes a production contract contradiction on protected main: .github/workflows/strix.yml says in-progress Strix is intentionally not cancelled because pre-publication cancellation loses the scanner log, but the same workflow sets PR-stable cancel-in-progress: true. Please keep this canonical scheduler/Strix owner lane and add RED→GREEN contracts for Draft↔Ready idempotence plus superseded-head/inactive cleanup. A bounded repair may use workflow cancel-in-progress: false with scheduler-owned, live-revalidated cleanup, or an equivalent same-head admission/coalescing guard; preserve cancellation only for verified superseded heads/inactive PRs. Do not cancel on elapsed time.
The current #1999 Strix run 34067362987 is itself in progress. Avoid a synchronize push that would reproduce evidence loss until it reaches a terminal state or the writer establishes another safe handoff. This finding is not approval, GREEN evidence, or merge authority.

Exact-head follow-up finding for d9de9a5ecaa5f6fd5ee8439381a29c7e97bf15a1: the same-head evidence-loss regression is repaired, but blanket workflow-level cancel-in-progress: false makes the documented superseded/inactive cleanup non-executable at the moment it is needed.
The workflow's own concurrency comment correctly says workflow-level admission gates the whole run. GitHub keeps the old run active and the replacement pending in the same PR-stable group. Therefore the replacement's cancel-superseded-pr-runs job cannot start until the old scanner finishes; it cannot promptly cancel an obsolete head or inactive PR. The new test only asserts literal false, so it does not distinguish the two required behaviors.
Please keep the RED evidence already added and narrow the fix to an event-sensitive executable contract:
- unchanged-head
ready_for_review/duplicate admission and same-head repository dispatch: do not cancel the executing scan; synchronize(new head),converted_to_draft, andclosed: allow workflow-level cancellation so the new event can enter, then retain the existing live repository/PR/head validation before any further destructive cleanup;- never use elapsed time.
Add contract cases that evaluate these event classes, not only grep the scalar. This preserves the #1706/#1150 finding while retaining prompt retirement for genuinely superseded/inactive runs. Until that is GREEN, the statement that existing cleanup remains responsible is not operationally true. This is not approval or merge authority.
|
Shared-writer coordination on exact heads #1938 Both independently modify
The executable combination needs event-sensitive cancellation: push and PR Do not merge either stale tree over the other, force-push, or transfer checks/approval. Prefer #1938 as the narrow concurrency prerequisite followed by non-force semantic reconciliation of #1999, or record an equivalent owner-agreed order before either merge. Exact-head tests/review must be regenerated after integration. |

Correction to my review 5127922244: do not implement its suggestion to set workflow-level The executable acceptance boundary is:
Current head This correction supersedes only the event-sensitive workflow-level cancellation paragraph; the same-head evidence-loss finding remains valid. |

Exact-head reconciliation and review-admission evidence for
The two current-head CodeRabbit findings are resolved and outdated: cleanup is no longer stranded behind a provider run because synchronized new heads and closed cleanup have independent group identities, while only a newer protected-ref Ready was restored at 2026-09-07T04:32:18Z strictly for review admission. The resulting exact-head runs are still non-terminal: Security Scan 34083472830, CodeQL PR 34083472892, SAST Semgrep 34083472922, Python Security 34083377117, Agent Review Runtime Quality 34083377126, Scheduler 34083473304, Noema 34083473285, OpenCode 34083473338, and Strix 34083473249. The Ready event cancelled only queued duplicate registrations; no executing provider evidence was cancelled. Hosted terminal checks and qualifying independent approval remain merge gates, not Ready prerequisites. No approval, auto-merge authorization, bypass, empty push, manual rerun, force update, review dismissal, or predecessor-evidence transfer was performed. |

Exact-head substantive review for 86aa8b79e596beb54685b9c7d9e470740f067081:
-
strixstill hasneeds: [changed-scope, admit-current-head]only. Onsynchronize, the exact-head provider can start beforecancel-superseded-pr-runsfinishes. This does not execute the already-recorded acceptance requirement that cleanup/preflight must gate provider admission, so old/new provider occupancy can overlap. -
The cleanup enumerator selects only
.event == "pull_request_target". A stale or inactive PR'srepository_dispatchStrix execution is therefore excluded from cleanup even when its authenticated target tuple is obsolete.
Please add RED fixtures for cleanup-before-provider ordering and stale/inactive dispatched executions, then repair them without workflow-level blind cancellation. Preserve #1938's protected-ref push coalescing and revalidate live repository/PR/base/head immediately before every cancellation. This is not merge-ready.

Preserved test-first repair is available without changing this PR's live head or interrupting its in-progress model review.
No predecessor evidence is transferred to the preserved child. The canonical branch will only be advanced by non-force fast-forward after the current Strix job is terminal, the live PR/head is revalidated, and the quick-gate hang is repaired or conclusively bounded. |

Follow-up on preservation commit The full harness contains 125 dynamic gate cases and did not finish within the additional local observation window even with test-only 1s/2s process/fake-sleep settings, so it remains unclaimed rather than being mislabeled as a cleanup regression.

P1 — forwarded leaf-close cleanup can wait behind the central Strix run it must retire.
At exact head 0c40ea18364dd80501636a8b9b3389f1adae82ec, the workflow-level group is PR-stable for both ordinary central strix-scan and forwarded strix-close-cleanup repository_dispatch events. However, cancel-in-progress is true only for protected-ref push or native pull_request_target synchronize/closed. A forwarded close has event_name == repository_dispatch and client_payload.pr_action == closed, so it receives the same group with cancellation disabled and remains pending behind the active central scanner. Its cleanup job cannot start, recreating the close-cleanup deadlock.
Acceptance: make only the authenticated close-cleanup dispatch cancel the same PR group (bind repository_dispatch plus client_payload.pr_action == 'closed', and event type if available), while an ordinary same-head strix-scan dispatch remains non-cancelling. Add an executable concurrency contract showing a central running scan is preempted/admission opens for the same-key close cleanup. Preserve the current rendered-name, exact identity, terminal completed/cancelled receipt, and live-PR guards. No elapsed-time cancellation or broad repository_dispatch cancellation.
GitHub does not allow this PR author identity to submit REQUEST_CHANGES on its own PR, so this COMMENT plus Draft lifecycle is the blocking record; it is not an approval.
|
Lifecycle correction at exact head The remaining defect is narrowly bounded: forwarded No source/ref overwrite, force update, review dismissal, or model-job cancellation was used. Restore Ready only after RED→GREEN for this dispatch-specific concurrency branch and fresh exact-head verification. |

This is the same canonical handler prerequisite now recorded on #2040 and producer/consumer cutover blocker recorded on #1902. This PR correctly remains Draft. No source commit, manual rerun, predecessor evidence transfer, or check bypass is warranted; after the handler-only prerequisite merges, non-force restack and fresh exact-head evidence are required. |

- Problem: Failed same-head checks remain for
c607604685d5f6d8ac2b5636d319dcbea4f1b031. - Root cause: The model-unavailable evidence fallback is allowed only when peer GitHub Checks are complete and clean.
