 - The **dashboard** (`${OMNIROUTE_DASHBOARD_PORT:-20128}`) is never registered in NPM at all, and `docker-compose.yml` never publishes that port to the host either — it manages every workload's keys, so it doesn't belong on the public internet, same reasoning as LiteLLM's old `/ui`. Unlike LiteLLM, OmniRoute's split-port mode means this is structural (no network route exists) rather than an NPM path-deny rule that has to be maintained and could be misconfigured. Reach the dashboard only from the host itself or over SSH port-forward.
 
 **Every gateway call already requires a valid API key** (Bearer token, see `docs/proxy-key-onboarding.md`), so no extra NPM-level auth is needed for the external hostname.

+## RAG knowledge graph (Neo4j) — `knowledge.proxy-ai.home`
+
+Set up as an NPM Proxy Host pointing at this machine's LAN IP on Neo4j's Browser port (`7474`, see `docker-compose.yml`'s `neo4j` service, [PR #50](https://git.arthurerlich.de/haylan/LLM-Server/pulls/50)). Internal-only, same as `proxy-ai.home` — no DMZ/external route, this is admin/dev tooling, not a client-facing endpoint. Bolt (`7687`, the actual query protocol) isn't proxied through NPM at all — clients on the LAN reach it directly at `<this-machine>:7687`.
+
+Qdrant's dashboard (`6333`) stays on its raw LAN IP/port for now — no hostname assigned yet.
