Satisfies the Phase 1 Definition of Done: - content/ validates cleanly against the frozen schema. `make validate` reports OK: 40 document(s) validated, 0 violations. - Six areas exist, each with an L1 entry: ai-overview, platform-overview, edge-overview, products-overview, history-overview, about-overview. - All six areas have an L2 entry: ai-systems, platform-estate, edge-fleet, products-business, history-engagements, about-narrative. - 28 L3 artefact stubs under content/<area>/l3/. Every artefacts[].url in every document resolves to one of them; the validator proves there are no dangling references (and a deliberately broken copy exits 1). - Every metric value traces to a source line in the evidence notes or the approved metric set in reference/content-map.md (per-metric citations are recorded in the AUD-131 completion comment). - Every document carries confidence and last_verified=2026-10-26; the validator rejects a missing or non-canonical value. - docs/content-redaction.md records the redaction pass: identifiers, third party personal data, credentials and infrastructure detail excluded, with reasons, plus the two numbers that are reported rather than smoothed. Honesty positions held: 3 businesses active (12 adoptions over time), Where-Woof deployed and pre-market, failures kept in (edge-failures), no promotion of in-progress work to delivered. No site code, no templates, no CSS, no rendering (Phase 2).

Artefact — Distributed audio · eight endpoints with ducking
Status: stub. The topology diagram and a short recording of ducking land in Phase 7.
What the artefact is
A Snapserver with eight Pi clients, Spotify and a local music server as sources, and one behaviour that matters more than the rest: when the house needs to speak, the music drops and the announcement plays everywhere, then the music returns to its previous level. Requests arrive by voice, so the same system that plays music is also the output for every automation and every answer.
What it proves
Multi-room audio treated as infrastructure with a predictable interruption behaviour — and the difference between "the speakers work" and "the speakers can be interrupted safely". Mains-powered nodes, bandwidth-heavy work, and a state machine for volume: the opposite design constraints to the battery nodes.
When it is delivered
