Point 7 of the page-wording review. The pages no longer show their data structure as headings, and they no longer explain their own conventions. - Level 1 is one screen: claim, status badge, three figures, the technology row, and one sentence carrying one link. Measured in headless Chrome at 1440x900: 1404-1845 px tall before, exactly 900 px (no scroll) after, on all six area pages. - DocPage: no kicker line, no visible level label, no "Evidence for this page" heading or instruction note, no "Drill-downs" list, no "Status <word> - sentence" footer. The artefact table starts at level 2, under the heading "Artefacts"; the history timeline is level 2 only. - Landing page: "Start here" link text gone, "How to read this site" panel gone, the footer's status-label explainer gone. - Content, presentation only, no claim softened: the leading H1 that duplicated the page title removed from all 41 documents; level 1 bodies reduced to the constraint as ordinary prose plus the way in; "**Status: ...**" prefixes removed from the artefact stubs; "## Drill-downs" and "## Period and confidence" removed from the level 2 pages, with the cross-area links moved into the prose. - The six level 1 claims are now sentences with a subject, and use commas instead of middots. Same facts, no new ones. Not in this commit: the 35 level 2 and 3 claims still use the compact CV style. That is a voice decision for Sam, not a wording tidy-up. make validate: 41 documents, 0 violations. go test ./...: pass. (cherry picked from commit 03009f80fc7815ad7719412e125df9297a6e653f)

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
