 ## Git Notes
 
 - If `git branch -d/-D <branch>` is policy-blocked, delete the local ref directly: `git update-ref -d refs/heads/<branch>`.
+- Bulk PR close/reopen safety: if a close action would affect more than 5 PRs, first ask for explicit user confirmation with the exact PR count and target scope/query.
