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 — Front door · vision · voice · and a rebuild
|
||
|
||
**Status: in progress.** The device was built and is being rebuilt. The page states this rather than describing it as finished.
|
||
|
||
## What the artefact is
|
||
|
||
A door unit with microphone, speaker, camera, button, PIR and mmWave presence. It detects a person, captures an image, logs it, has the image described, and announces to the house who is at the door before offering a spoken greeting; the visitor's reply is captured and played over the house speakers, with an alert pushed to a phone. Voice output ran on one provider and now runs on a cloned voice with a fallback to a local synthesiser.
|
||
|
||
## What it proves
|
||
|
||
Vision, voice and actuation in one device under real constraints — latency that a person at a door will tolerate, and a failure mode that must be polite.
|
||
|
||
## Limits stated on the page
|
||
|
||
The measurement it is being rebuilt around: presence detection with a time-of-flight ranging sensor, to stop the unit greeting people who are walking past rather than standing at the door. Until the rebuild is finished the honest label is `in-progress`.
|
||
|
||
## When it is delivered
|
||
|
||
Phase 7 for photos and the sensor change. Source: evidence notes section 1.
