Adds platform/lab-router/ — a narrow service that runs on the Lab Host, authenticates the Gateway via mTLS, and resolves an opaque routing token to a local container purely from Docker label state (no Postgres access, no callback to the Provisioner). Replaces the Gateway's env.internal_ip assumption (only valid when Gateway and Lab share a Docker daemon) with a data-driven direct/router decision per lab_host (lab_hosts.routing_mode/router_endpoint, migration 004), resolved in one place (platform/gateway/src/lab-endpoint.js's labTarget()) that every proxy/fetch call site in server.js now goes through. Extends the existing Docker TLS CA (infra/scripts/docker-tls/generate-docker-tls.sh) with a second mTLS leaf pair (router-server/gateway-client) for this new data-plane connection, deployed by the docker-tls Ansible role into a separate directory from the control-plane pair. Firewall (rn-lab-host-01.rules) replaces the old speculative wide port-range allowance with one narrow rule: platform_ip -> the Router's port only. dev-local stays routing_mode: direct — zero behavior change for local dev, confirmed by the full existing regression suite passing unmodified.
Production Provisioner config overlay
Deployed by the platform Ansible role to /etc/rootnode/provisioner-config/ on
rn-platform-01 (PROVISIONER_CONFIG_DIR), replacing the dev-only files shipped in
platform/provisioner/config/.
lab-hosts.yaml— points at the real rn-lab-host-01 VM over TLS instead of the dev Unix socket. TLS paths reference material generated byinfra/scripts/docker-tls/and deployed by thedocker-tlsAnsible role — never checked into this repo (seeinfra/docker/tls/.gitignore).resource-policy.yaml— deliberately still the Phase 1 dev defaults, unchanged, with a loud comment explaining why. Per the explicit Phase 4 instruction: do not hard-code final per-Lab CPU/RAM numbers before the real host is benchmarked (docs/CAPACITY_PLANNING.md). Whoever runs the first production load test (infra/scripts/loadtest/) updates this file with real measured numbers, not this deployment.
