A digest of the inventory — grouped by purpose, with addresses removed — lands in Phase 7.

## What the artefact is

The inventory generated from the hosts, grouped by purpose: media and file services, home automation, the AI services, the public edge, and the build tooling. For each service the same three facts are recorded — port, configuration folder, memory cap.

## What it proves

That the estate is inventoried rather than accumulated, and that the resource rules are applied per service instead of being a policy on a wiki page.

## When it is delivered

Phase 7, generated from the live hosts. Counts follow the approved metric set; the exact number is regenerated at capture time.
