Sources for every figure on this site
The build refuses to ship a page containing a statistic that is not in this table. Where a figure is a snapshot or an estimate, the caveat is printed with it rather than left off.

Footage
Every full-bleed band on this site is a seven-second loop built from one of two kinds of source. Filmed footage is licensed from Pexels and the photographer is credited on the band itself as well as here. Generated footage is abstract by construction - it depicts no person, no place, no record and no interface, and it is labeled as generated wherever it appears.

On what the footage may show
No frame on this site shows an identifiable child. Every candidate clip was reviewed as a still before selection, and clips containing identifiable faces, brand marks, or readable third-party text were rejected rather than cropped. The generated clips were prompted with an explicit prohibition on people, faces, hands, children, text, logos and interfaces, and were reviewed on the same basis.
The page explainers
Every page carries a narrated "How this works" video. Each one is assembled from that page's own full-bleed loop - so its footage is credited in the table above - with a drawn title card, caption band and end card. The narration is synthetic speech, and the transcript printed beside each video is the text that was sent to the voice engine, not a transcription of the audio.

On the narration
The voice is generated, not recorded, and it is labeled as generated here and on every page that plays it. No person speaks on this site. Nothing in these videos depicts a real place, a real record or a real encounter - the footage behind them is the same licensed and generated material inventoried above.
Provenance of the specification
The Anchored Zone Protocol
A substantial part of this site is carried across from the Anchored Zone Protocol, a draft specification dated 21 August 2026 and supplied as a source document. Where that document and this site's earlier drafts disagreed, the Anchored Zone Protocol was taken as authoritative - it is the more rigorous of the two and it is the better sourced, and three of its findings reversed design decisions that had already been published here.
Its 37 primary sources are reproduced in full at sources, keyed so every figure on this site cites into them. Its open questions are reproduced at open questions without softening, including the items its own author marked as unverified.
What changed here as a result is recorded rather than quietly overwritten: the peer-to-peer sensing model was withdrawn on physical grounds, the claim that tokenization supplied legal authorization was withdrawn on Grady, and the alert ladder was rebuilt around cross-modality agreement and zone classification.
A second revision, and a figure this site had to withdraw
A revised Protocol followed. Its changes are small in volume and almost entirely a precision pass - claims made narrower, figures shown with their derivation, and two of its own open questions closed. Several of them corrected things this site had already published.
The one worth naming: an earlier draft stated that measured nuisance variance from antenna orientation alone was 19 dB. The revision withdraws that figure. What the source actually supports is that changing which person sits in a seat moves the reading by about ten decibels - before orientation, pockets, walls or crowds are considered at all. The conclusion is unchanged and arguably stronger, because nuisance variance from a single variable already exceeds the entire usable signal. But the number was wrong here for a day, and saying so is cheaper than being caught with it.
Also narrowed: passive tags cannot detect one another without an external illuminator - carrier-assisted tag-to-tag communication does exist in the literature, at sub-meter range, with a separate reader flooding both tags. An absolute claim with a known counterexample is exactly what an informed reviewer takes apart, so the site now carries the exception.
The Anchored Zone Assessment
A companion document arrived alongside the revision: a decision-support assessment arguing whether the system should exist at all. It is the source for what it solves, the nineteen problems at unsolved, and the roadmap at what to add.
Its judgment on one point is worth recording. It ranks a warning delivered to the monitored person as the single most valuable addition available - and that page was already built here, from the same instinct, before the assessment was supplied. Two independent routes to the same conclusion is the closest this document gets to a result.
How this site was built
- Static HTML, generated by a build script. No framework, no analytics, no third-party requests of any kind - enforced by a build gate, not by intention.
- The instruments are plain JavaScript in
/assets/engine.js. They compute in your browser, make no network calls and store nothing. - Loops encoded with ffmpeg; the wrap is a one-second cross-dissolve of the clip's tail over its head, so the join is continuous.
- Footage licensed from Pexels under the Pexels license. Generated clips from OpenAI Sora 2.
Status of this document
This is a design document. No system described here has been built, procured, piloted or deployed, and nothing on this site should be read as describing an existing program. It is published so the concept can be argued with before anyone spends money on it.

Transcript
| At | Section | What it says |
|---|---|---|
| 0:02 | What it is | This is the provenance page. Every figure has its source, and every clip has its origin, set out where a reader can check the two side by side. |
| 0:11 | Filmed or generated | Each loop says which it is. Filmed footage is licensed and the photographer is credited. Generated footage is abstract, and it is labelled as generated wherever it appears. |
| 0:21 | What the footage shows | No frame shows an identifiable child. Clips with faces, brand marks or readable text were rejected rather than cropped, and the generated clips were prompted against people. |
| 0:32 | Where the document came from | Much of this site is carried across from a draft specification supplied as a source document. Where it disagreed with earlier drafts here, it was taken as authoritative. |
| 0:41 | A figure withdrawn | A later revision withdrew a figure this site had already published. The correction is recorded on the page rather than quietly overwritten in place. |
| 0:49 | Why that is written down | Three findings reversed design decisions that had already gone out. Saying so is cheaper than being caught with the old version still standing behind them. |
