AI assistance

Implemented with OpenAI Codex (GPT-6). A separate read-only AI reviewer inspected the complete two-file change against base 4464279692ae9901e284631ea73785dbd8510718. Its sole finding about an ambiguous status-write response was corrected and rechecked; no material findings remain. This local review does not substitute for the repository's current-head review receipt.

What changed

Add fixed reason codes to each clearing-label recorder no-op and explicit warnings when an expected clearing label cannot produce a status. At event matching, log only the payload timestamp, authorized candidate-event timestamps, exact match count, and head/PR equality booleans. Preserve API failures; report an unconfirmed status-write outcome without retrying.

Acceptance semantics are unchanged: observability only. The existing sender, open-PR, payload head/number, event actor/label, unique exact timestamp match, and status binding remain intact. The evaluator, including revocation checks, is byte-for-byte unchanged. No timestamp window, latest-event fallback, or approval bypass is introduced.

How verified

• 8 focused unittest methods passed, including existing Dependabot cases and recorder fixtures for all no-op reasons, exact timestamp mismatch, duplicate events, wrong actor/label/event, payload-head/PR/event binding, and API failure before/after a write.
• Ruff, actionlint and git diff --check passed.
• Documentation check: 0 blocking findings; 1 existing README outline advisory.
• Gitleaks 8.30.1: exit 0, 0 findings on the local two-file commit range from the stated base. The published Git tree is identical to that tested and scanned tree.
• Compared workflow sections: triggers, permissions, action pin, environment, evaluator, exact event predicate and status payload are preserved.
• The full runtime suite and live label event were not run; no workflow dispatch was performed.

Why

A prior recorder run for #682 completed without a clearing-label record and without identifying its early-return path. These diagnostics provide evidence for the next natural label delivery. They do not establish the original cause or fix clearing-label acceptance.

Risk

High: trusted workflow path. Only the recorder and its existing workflow-test file change. The equality fields are diagnostics, not new gates: head equality compares the payload head with context.sha (which can be the base SHA for pull_request_target); PR equality compares the payload number with context.issue.number. No tokens, keys, full payloads or account secrets are logged.

Keep this PR as a Draft. #682 and #683 remain untouched. No approval label, undraft, merge, status fabrication, deployment or production action is authorized by this change.
