- Fix F1: Prepare recovery worktree detached at remote_head without git checkout -B to avoid exit 128 when branch is held by source worktree
- Fix F2: Pass recovery_sanctioned=True in bind_session_lock and assess_same_issue_lease_conflict
- Fix F3: Add SOURCE_RECOVER_DIRTY_ORPHANED to SANCTIONED_LOCK_SOURCES
- Fix F4: Stop after Phase 4 dirty apply when conflicts exist; do not finalize session binding
- Fix F5: Dynamically query competing live locks and workflow leases in MCP server
- Fix F6: Fail closed on recovery worktree resume when HEAD does not match expected remote_head
- Fix F7: Fail closed on remote HEAD observation failure rather than copying expected_remote_head pin
- Fix F8: Enforce foreign overwrite protection requiring same claimant or sanctioned reclaim
- Fix F9: Add real multi-worktree integration tests for prepare_recovery_worktree and lock rebind
- Fix TestWorktreeStart: Bypass session lock check for dry-run and review/pr-* branches in scripts/worktree-start
Add an explicit recovery operation for same-claimant dirty registered
worktrees under malformed PID-less durable locks, with crash-safe journals,
dirty byte preservation, path-level conflict detection, and live session
binding. PID-less locks are never treated as live merely because expiry is
absent.

An expired author issue lease could not be renewed by the exact session that
already owned it. `assess_same_issue_lease_conflict` computed same-owner
evidence and then returned on the expired branch before consulting it, and
`assess_expired_lock_reclaim` only permits takeover on a dead PID or a missing
worktree. Because the recorded PID is the long-lived MCP daemon rather than the
authoring task, a lease that expires under a live daemon is the ordinary case
for any author task outliving the TTL — and in that case the owner's own lock
became permanently unmodifiable through sanctioned tools.
Add `issue_lock_renewal`, a pure evidence assessor for that one case, and
evaluate its disposition before the expired foreign-takeover return.
Renewal requires an exact match of remote, org, repo, issue number, operation
type, branch, realpath-normalized worktree, claimant username, and claimant
profile; a registered worktree that exists, sits on the locked branch, and is
clean; local and remote heads that agree; and, when an owning PR exists, a PR
head that agrees too. No competing live lock, competing branch claim, or other
owning PR may exist. Any missing or contradictory evidence fails closed.
PID liveness is never authorization: it is recorded as evidence and is neither
necessary nor sufficient (AC16). Only an expired lease is ever a candidate, so
a live foreign lease stays non-recoverable (AC12) and dead-PID takeover keeps
its existing #601 conditions (AC11). Renewal is never caller-declarable — the
waiver is server-computed and `gitea_lock_issue` gains no parameter (AC14).
A sanctioned renewal records prior PID, prior expiry, replacement PID, new
expiry, claimant, and its supporting proof under `lease_renewal`, and reuses
the #772 compare-and-swap so two sessions observing the same expired lease
cannot both win.
Absolute wall-clock expiry is preserved. Sliding heartbeat renewal, fencing
tokens, and the shared cross-role lifecycle remain #790's scope and are
deliberately not implemented here; #790 stays sequenced behind this change.
Tests: 40 new cases covering the positive path, every near-match and
foreign-owner refusal, the non-candidate cases, the gate-ordering regression,
the renewal record, downstream mutation ownership, and AC14/AC17. Two #772 test
doubles now forward the new keyword.

Closes#772
Recovery now dispatches on observed publication state: published_owning_pr
(remote branch exists; head equality #753 or strict descendancy #768,
unchanged) and unpublished_claim (no remote branch, no PR; ownership proven
by the durable lock record plus a local HEAD strictly descending from the
server-observed base the branch was cut from).
The absence of a remote head is never itself permission. Recovery writes are
compare-and-swap against a lock generation, and the mutating lock path and
read-only diagnostic assessor share one evaluator.

Rebase onto master (#443 keyed store) and port #438 hardening: per-issue
fcntl.flock around bind_session_lock, assess_lock_freshness with dead-PID
detection, verify_lock_for_mutation before create_pr, and live lock
inventory for claim visibility.

Store per remote/org/repo/issue locks under GITEA_ISSUE_LOCK_DIR with
atomic writes and per-session binding. Integrate own-branch adoption for
lock recovery, update worktree-start and cleanup reconcile, and add tests
documenting the ban on manual global lock seeding.
