Merge Risk: 🔵 Low · up to A Dependabot push during approval can leave an approval on a commit the triage flow did not evaluate. The exact-head merge check prevents this flow from merging that newer commit, but repository controls may still see its approval; bind approval to the tested SHA before relying on this skill.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick winRe-check the PR state before emitting and mutating candidates.
The initial open search is not atomic. A PR can close before
gh pr viewruns, andsnapshot.pydoes not checkdetails["state"], so it can emit a closed PR as a candidate.Step 3 requires an open-state check, but the merge gate does not repeat it after the final checks. A PR can close after that check and still reach the approval or merge commands. Add an open-state rejection to the snapshot and to the final merge gate.

GitHub REST API Create a review commit_id omitted latest commit pull request review official docs
💡 Result:
Yes. In GitHub’s **Create a review for a pull request** endpoint, `commit_id` is optional. If you omit it, the review defaults to the PR’s **most recent commit**. ([docs.github.com](https://docs.github.com/en/rest/pulls/reviews))
So you can leave `commit_id` out of the request body. If you’re adding inline comments, the docs warn that using a non-latest commit can make a comment outdated if later commits change that line. ([docs.github.com](https://docs.github.com/en/rest/pulls/reviews))

Bind the approval to the reviewed head SHA.
The merge gate records <sha>, but gh pr review --approve does not bind approval to that SHA. A push between the head check and approval can attach approval to an unreviewed commit. --match-head-commit <sha> can block the later merge, but it does not correct the mismatched approval.
Recheck the head before approval, restart the gate if it changed, and submit the approval through the review API with commit_id=<sha>.
