-
-    Explicit recovery operation — does **not** silently widen ``gitea_lock_issue``.
-
-    Accepts authoritative expected pins (repository, issue, branch, source
-    worktree, claimant, local head, remote/PR head, dirty fingerprints) and
-    fails closed on any mismatch. PID-less malformed locks are never treated
-    as live merely because expiry is absent. The source worktree is frozen;
-    recovery prepares a separate worktree at the pinned remote head, re-applies
-    dirty bytes with path-level conflict detection, and binds a live author
-    session only after recovery state is consistent.
-
-    Args:
-        issue_number: Issue whose durable claim is being recovered.
-        branch_name: Locked branch ``(fix|feat|docs|chore)/issue-N-…``.
-        source_worktree_path: Registered dirty source worktree under branches/.
-        expected_local_head: Full 40-char SHA of the source worktree HEAD.
-        expected_remote_head: Full 40-char SHA of the remote/PR head to sync to.
-        expected_dirty_fingerprints: ``{relative_path: sha256}`` of dirty bytes.
-        remote/host/org/repo: Repository binding.
-        recovery_worktree_path: Optional recovery worktree path under branches/.
-        dry_run: Assess eligibility only; no filesystem or lock mutation.
