See each PR's review verdict as a label on the PR list
Review verdicts now appear as labels on your open pull requests, so you can tell what is mergeable from the list itself.
Telling which of thirty open pull requests were clean meant opening thirty of them, because the verdict lived inside each PR's status comment.
Verdict labels on every PR
Each reviewed PR now carries a label that matches its verdict: review/lgtm when the review came back clean, review/needs-changes when findings are outstanding, review/wrong-approach when the shape needs a call from the code owners, and review/parked when the review is no longer being retried. A PR carries at most one of them, so the list reads at a glance.
A PR nobody has reviewed yet, and a PR under review right now, carry none of these labels.
Green that stays honest
A clean verdict drops its label as soon as new commits land, so review/lgtm means mergeable as it stands rather than approved at some commit since buried. You get the same pair of checks the automated sweeps run before they land one of their own PRs.
Backfilled and self-correcting
PRs reviewed before the labels existed pick up the right one, and a label someone strips by hand comes back. Delete the status comment to force a fresh review and the label comes off to match.
Open your pull request list and sort or filter on review/lgtm to see what is ready to merge without clicking through.
