nx_lock_reap_core.nx

nx_lock_reap_core.nx -- importable CORE of the SOVEREIGN stale-lock reaper (R-ORCH-2a; the BUILD(missing) gap the triage flagged + the exact class that blocked commits this session, now mechanized as an ORGAN instead of the ps|grep|rm shell sin). A workstream that crashes mid-write can leave a stale lock (git index.lock, a WMS lease, cp_deploy.lease, a reconcile lock) blocking every sibling -- exactly what the orchestration north-star must never let a crash cost. This reaps such a lock, but ONLY when it is provably abandoned. FAIL-SAFE BY CONSTRUCTION (the load-bearing property, gate-proven): reap iff the lock EXISTS AND no OWNER process is alive (a /proc cmdline scan for the owner needle -- authoritative for same- kernel NAS/WSL processes) AND it is older than the age threshold. A live-owned lock is NEVER reaped (even if old); a fresh lock is NEVER reaped (a legit in-flight op). Default = do nothing. (Cross-boundary note: a Windows git.exe holding /mnt/c/.git/index.lock is NOT visible in WSL /proc; that case is closed by the sovereign-commit path, not this reaper -- honest scope.) license_tier: ORIGINAL
