Architecture for 150+ nodes: - global_capabilities_client.py: NATS scatter-gather discovery using wildcard subject node.*.capabilities.get — zero static node lists. New nodes auto-register by deploying NCS and subscribing to NATS. Dead nodes expire from cache after 3x TTL automatically. Multi-node model_select.py: - ModelSelection now includes node, local, via_nats fields - select_best_model prefers local candidates, then remote - Prefer list resolution: local first, remote second - All logged per request: node, runtime, model, local/remote NODA1 compose: - Added node-capabilities service (NCS) to docker-compose.node1.yml - NATS subscription: node.noda1.capabilities.get - Router env: NODE_CAPABILITIES_URL + ENABLE_GLOBAL_CAPS_NATS=true NODA2 compose: - Router env: ENABLE_GLOBAL_CAPS_NATS=true Router main.py: - Startup: initializes global_capabilities_client (NATS connect + first discovery). Falls back to local-only capabilities_client if unavailable. - /infer: uses get_global_capabilities() for cross-node model pool - Offload support: send_offload_request(node_id, type, payload) via NATS Verified on NODA2: - Global caps: 1 node, 14 models (NODA1 not yet deployed) - Sofiia: cloud_grok → grok-4-1-fast-reasoning (OK) - Helion: NCS → qwen3:14b local (OK) - When NODA1 deploys NCS, its models appear automatically via NATS discovery Made-with: Cursor
