traefik-multi-network-container-backend-routing-failure

When a container is attached to multiple Docker networks and Traefik has no traefik.docker.network label, Traefik picks whichever network IP it resolves first — which may be an internal network Traefik cannot reach, causing backend timeouts. Fix: add traefik.docker.network=<network-traefik-is-on> label to the container’s compose service and recreate the container. Affected container: researchclaw on mcp-global-network + graphiti_oracle-internal.
