             `gh pr create` against master. The PR body must summarise the delta: counts of new /

+            ## 8. Enable auto-merge
+            After the PR exists (whether newly created or the existing one you pushed onto),
+            enable auto-merge so it lands on master once its status checks pass:
+            `gh pr merge --auto --squash --delete-branch "<pr-url-or-number>"`.
+            Auto-merge only completes when the required checks are green, so a migration that
+            fails the build/integrity gate will never merge. Do not attempt an immediate or
+            admin merge; if enabling auto-merge fails (e.g. it is not enabled on the repo),
+            report that in the run output and leave the PR open rather than force-merging.
