# Artefact — House AI hub service topology

**Status: stub.** The diagram and the generated topology dump land in Phase 7 (polish). This stub exists so the level 2 page has no dangling reference.

## What the artefact is

A one-page diagram of the hub: request intake (voice · chat · scheduled job), the gateway hop, the pipeline runners, the retrieval path, and the output paths (house speakers, phone alerts, dashboards). Every box is a service that runs; nothing on the diagram is aspirational.

## What it proves

That the estate is a designed system with a single gateway and a single set of namespaced tools — not a collection of scripts that happen to share a machine.

## When it is delivered

Phase 7. The source facts are in the evidence notes (sections 2 and 4). Capture must be from the live estate, so no diagram is drawn from memory in Phase 1.
