+## Code review
+
+Every PR gets a genuine advisory AI code review
+(`.github/workflows/claude-review.yml`) that posts findings as comments — it is
+not a required check and never blocks a merge. A second workflow
+(`.github/workflows/auto-approve.yml`) then submits a formal approval as
+`github-actions[bot]` — an identity distinct from the PR author — which OSSF
+Scorecard's Code-Review check reads from the reviews API. The maintainer still
+merges every PR.
+
+This credits Code-Review via automation rather than peer review, because the
+project is currently single-maintainer. OSSF documentation suggests
+automated/AI reviews may not be intended to count toward this check; the current
+setup does credit them, and a future Scorecard release could change that.
+Removing `auto-approve.yml` cleanly reverts the check with no other impact.
