28 Expected last_heartbeat for conditional update (optimistic concurrency). Use literal 'NO_HEARTBEAT' to claim an unclaimed lease (first heartbeat). For subsequent heartbeats, echo the server's previous last_heartbeat value exactly. Returns 412 Precondition Failed if the actual value doesn't match.
