 ## Implemented boundary
 
 - Production automation explicitly selects `docker-compose.yml`; the auto-loaded override was replaced by explicitly selected `docker-compose.dev.yml`.
-- Base Compose publishes no frontend, backend, ai-service, or bundled-Ollama host port. Development adds 3000, 5202, and profile-scoped 11434.
+- Base Compose retains the frontend's production compatibility port 3000 because the operator-owned reverse proxy still targets that host port. Backend, ai-service, and bundled Ollama remain unpublished; development additionally exposes backend 5202 and profile-scoped Ollama 11434.
 - Nginx and backend communicate over an internal dedicated CIDR; the backend accepts exactly one forwarded hop only from that CIDR.
 - Nginx derives its application server name from `APP_PUBLIC_BASE_URL`, rejects other Hosts except `/health`, and preserves Traefik's replaced proto/client headers rather than substituting internal HTTP.
 - Deploy preflight requires and validates the canonical origin and dedicated proxy CIDR. CI post-deploy commands use the production Compose file explicitly.

 ## Limitations and production gates
 
-- No Traefik configuration exists in this repository. Verify its exact `Host()` rule, TLS route, replacement of forwarding headers, selected Docker network, and hostile-Host rejection on the operator host.
+- No Traefik configuration exists in this repository. Production verification proved it still targets host port 3000, so that compatibility ingress remains. Migrate Traefik onto `jobtracker_shared`, verify its exact `Host()` rule/TLS/header handling, then remove the host port in a coordinated release.
 - `WEB_PROXY_SUBNET` must be chosen after production Docker-network inventory. Deploys recover a missing value from a uniquely labelled existing Compose `web_proxy` network. On its first creation, the documented `172.31.250.0/29` candidate is accepted only after a complete Docker network inventory proves it does not overlap; unreadable or overlapping inventory remains fail-closed.
 - Host firewall and `docker ps`/published-port state are unverified.
 - The exact `nginx:1.29.8-alpine` base image was not installed locally. Syntax was checked with the existing local nginx frontend image; approved CI must build the pinned Dockerfile.
