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)

One annotated diagram of a representative node and the radio path lands in Phase 7.
|
||
|
||
## What the artefact is
|
||
|
||
The per-node pattern: 240V step-down or solar with a LiFePO battery and charge controller, an ESP32 in deep sleep, a wake source (timer, radio, or a physical input), a relay or driver for the load, and an MQTT message into the automation layer. Around it, the reason each node uses LoRa, Zigbee or Wi-Fi.
|
||
|
||
## What it proves
|
||
|
||
Power budgeting and remote wake as design decisions, not hobby wiring — and an architecture that survived being repeated across twenty nodes.
|
||
|
||
## When it is delivered
