PR Review Loop

Hard Rule

Do not merge a PR merely because CI is green, the branch is mergeable, review threads are outdated, or no current Codex thread is visible.

Merge only when one of these is true:

• Codex has finished reviewing the latest head and left an explicit thumbs-up approval signal.
• The user explicitly overrides this gate with language like "merge without waiting for Codex approval" or "override Codex gate".

Codex often leaves that thumbs-up as a reaction on the PR description/body itself (the GitHub Issue/PR object), not on its "Codex Review" issue comment. Do not only inspect issue comments.

If Codex's newest fresh reaction on the PR body or a relevant comment is eyes, it is reviewing. Wait and keep checking.
