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)

A short recording of music ducking under a spoken announcement lands in the optional voice phase. Text describes the chain until then.
|
||
|
||
## What the artefact is
|
||
|
||
The chain: an ESP32 device with a microphone detects the wake word and confirms with an LED, audio is transcribed locally with Whisper, the request goes through the gateway, and the reply is spoken through Piper or the MiniMax cloned voice over all eight Snapcast endpoints, with music lowered for the announcement and restored afterwards.
|
||
|
||
## What it proves
|
||
|
||
Voice treated as a system front-end with latency and reliability requirements — not a party trick bolted onto a chatbot.
|
||
|
||
## When it is delivered
|
||
|
||
Recording in the optional voice phase (Phase 7). The endpoint count and the ducking behaviour are from the evidence notes, sections 1 and 2.
