+# Runtime and Deployment
+
+## Authoritative Compose Policy (Canonical)
+Authoritative configuration is **per-node manifests**.
+- NODE1: `docker-compose.node1.yml`
+- NODE3: `docker-compose.node3.yml`
+- Staging: `docker-compose.staging.yml` (+ override)
+
+`docker-compose.yml` is non-authoritative for production drift checks (local/legacy/node2-like context).
+
+## Drift-Check Policy
+Drift check runs per node and compares:
+- service list / images / tags
+- ports / volumes / networks
+- env vars (non-secret subset)
+- healthcheck definitions
+
+Recommended structure:
+- `ops/compose/production/` for canonical links/copies
+- `ops/drift-check.sh` with `NODE_ROLE=node1|node3|staging` resolver
+- timer/cron per node (or central orchestrator via SSH)
+
+## Proxy Ownership Policy
+- Exactly one edge proxy owns `80/443` in production.
+- Second proxy must be disabled or internal-only (`127.0.0.1` / private network).
+- Current repo evidence: nginx edge config exists (`ops/nginx/node1-api.conf`), Caddy exists for integration UI use case (`infra/compose/Caddyfile`), runtime docs describe conflict history.
+
+## Node Runtime Notes
+- NODE1: full primary stack and data layer in `docker-compose.node1.yml`.
+- NODE3: GPU edge services with dependency on NODE1 NATS/S3 endpoints.
+- Staging: separate internal network and override that removes most host-exposed ports.
+
+## Quickstart (Operational)
+1. Select node role and authoritative compose file(s).
+2. Ensure required network exists (`dagi-network` for NODE1/NODE3 external mode).
+3. Start infra core then app services per node compose.
+4. Run per-node health and drift checks.
