The primary guarantee is wiring reconciliation — a declared enforcement that no hook invokes, or whose exit code a hook swallows, is a failure rather than a passing line. It reads nothing of the checkout's server, its lease or the mesh: a stale server is reported by `majordomus serve status`, the mesh by `majordomus mesh doctor`, and the server's own health by GET /api/v1/health and GET /api/v1/ready.
