Phase 3 of plan.md. Device registration with one-time secrets, scoped single-use socket tickets, the lock-owner WS /nodes/ws with handshake and heartbeat eviction, a single batch ConsentGate, and NodesService which disconnects nodes within one tick when consent, device or the nodes_enabled kill switch changes. A reconcile of 2000 sessions measured about 110 ms after replacing per-session queries with batches. Devii may withdraw but never grant bandwidth_sharing.
