+**Issue-lock recovery (#447):** Do not manually seed, restore, or delete
+`/tmp/gitea_issue_lock.json` as a normal recovery path. That file is global
+shared state and manual writes can clobber another session's live lease. Use
+`sanctioned recovery` instead:
+
+1. `gitea_lock_issue` on a clean `branches/` worktree (normal path).
+2. Own-branch adoption via #442 when the issue's exact branch is already pushed.
+3. Operator override only when explicitly authorized — record
+   `External-state mutations` and `operator override proof` in the final report.
+
+`gitea_create_pr` rejects lock files that lack sanctioned `lock_provenance`
+metadata. Final-report validation blocks handoffs that hide lock read/write/delete
+under `External-state mutations: none` or mix author PR creation with reviewer
+approval in one run. See also #438 (global lock redesign).
+
 Remote branches matching the issue number are also treated as active work unless
 the recovery review proves the branch is abandoned or superseded. Never delete
 or clean up a branch when it has an active lease, dirty worktree, open PR, or is
