Add fail-closed assessment and MCP tool for expired/superseded-head
comment-backed reviewer leases that lack a control-plane lease_id.
- assess_obsolete_reviewer_comment_lease_cleanup eligibility matrix
- diagnose classifications: foreign_active_current_head,
foreign_expired_current_head, foreign_completed_superseded_head,
foreign_expired_superseded_head, orphaned_owner_missing,
ambiguous_conflicting_evidence
- gitea_cleanup_obsolete_reviewer_comment_lease with confirmation
CLEANUP OBSOLETE REVIEWER LEASE <n> and controller_recovery_authorized
- preserve audit history via append-only phase=released marker
- never repoint, transfer validation, use PID ownership, or steal
active current-head foreign leases
- regression for PR #688 lease comment 10749 after recorded expiry
find_active_reviewer_lease walked past terminal markers and re-armed
older claimed leases after gitea_release_reviewer_pr_lease. Treat the
newest marker as authoritative (append-only ledger).
Closes#577
Replace manual in-process _SESSION_LEASE seeding with an auditable
gitea_adopt_merger_pr_lease tool that posts durable adoption proof and
records sanctioned session provenance. Mutation gates now reject bare
record_session_lease calls without provenance from acquire/adopt/heartbeat.
Closes#536
Refuse merge-oriented reviewer-lease acquisition/adoption on an already
merged/closed PR, and add a read-first cleanup path for a lingering moot lease.
- reviewer_pr_lease.assess_acquire_lease: new pr_merged_or_closed flag; fail
closed with a post_merge_moot reason and no lease body when the PR already
merged/closed.
- reviewer_pr_lease.assess_post_merge_moot_lease: pure assessment. Only treats a
lease as moot when the PR is merged/closed; never proposes touching an active
lease on an open PR; provides a terminal phase:released (blocker:
post-merge-moot) body to neutralise the moot lease append-only; idempotent
once the released marker is the newest entry.
- gitea_acquire_reviewer_pr_lease: fetch live PR state, pass the flag, surface
post_merge_moot on refusal (no comment posted).
- gitea_cleanup_post_merge_moot_lease: new read-first tool. Reports merged
state, merge_commit_sha, linked-issue closure, lease-moot, cleanup
performed/skipped, and no_merge_or_adoption. apply=True posts the released
marker only when merged/closed with an active lease; refuses on open PRs.
- tests/test_post_merge_moot_lease.py: 10 tests covering acquire refusal on
merged PR (no post), safe/idempotent cleanup, and open-PR foreign-lease
protection.
No relaxation of #407 reviewer-lease or #16 gated-merge gates for open PRs.

Structured PR-thread leases with acquire/heartbeat MCP tools and
mutation-time enforcement so reviewers cannot race the same PR queue.
