Refs #1 - peers table (peer_id, addr, cursor, last_handshake) - watch serves HTTP API: GET /v1/ping (knowledge vector), GET /v1/log?node=&after= (cursor-paged pull), POST /v1/obs/batch - anti-entropy sweep (Run): ping, pull what we lack, push own obs; echo suppressed by node_id ownership; reconcile-on-pull - config via KNOX_PEERS / KNOX_PEER_ADDR; knox gossip status - db: GossipObservation wire type, PushObservations, ObservationsAfter, KnowledgeVector, peer upsert/list - integration tests: bidirectional convergence + idempotency
