Phase 1: content source of truth — 40 documents across six areas

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 — Commercial signage on commodity hardware
+
+**Status: delivered, with a rebuild in progress.** The product shipped and customers still run it. The rebuild on the current stack is not finished and is labelled as unfinished everywhere it is mentioned.
+
+## What the artefact is
+
+The product in use: a player on commodity hardware — a small Raspberry Pi or a microcontroller class device — driving any HDMI screen, with fleet control from the platform: switch screens on and off, rotate, mirror, lay out multiple screens, coordinate boards, and synchronise playback across a site. Content is built by the customer from complex animation down to a simple image rotation, and the system adapts to the board it finds rather than demanding a specification.
+
+## What it proves
+
+The commercial read: a market was overpriced, the substitute was built on commodity hardware, and it was sold and operated for years. Twelve adoptions over time, three businesses still running. That is a product, not a project.
+
+## Limits stated on the page
+
+Twelve is cumulative adoption and three is the current count — the distinction is kept because inflating it would be the easiest lie on this site. The rebuild is in progress. No revenue figures or customer names beyond type of business are published.
+
+## When it is delivered
+
+Phase 7 for screenshots and a demonstration recording, captured from the running product. The one-liners for reference customers are approved for the salon and the financial services business only.

+# Artefact — The site builder behind the signage
+
+**Status: delivered, retained.** Retired as a general-purpose product; kept as the content engine for the signage.
+
+## What the artefact is
+
+The templated builder: pick a template, build the site, publish it — with editors for drawing, images, video and text animation, video effects and transitions, 3D object import and text extrusion, plus document and office-format handling. Image animation is composed in JavaScript and HTML and rendered on Raspberry Pi hardware through Python. Around the site itself sat the commercial scaffolding a small business actually needs: shop, invoicing, room and event management, presentations, document management, client records and bulk email and SMS.
+
+## What it proves
+
+Two things at once — depth in media pipelines (FFmpeg, ImageMagick, PDF and office formats, three.js) and the discipline of shipping a general product that strangers could operate without help.
+
+## Limits stated on the page
+
+The surface was too large for one person to support indefinitely. The plan recorded here is to strip it back to signage plus the content engine and stop selling the rest, which is a decision about focus rather than a claim of failure.
+
+## When it is delivered
+
+Phase 7 for a screen recording of the editors. Source: résumé (2014–2020 freelance) and evidence notes section 3.

+# Artefact — Where-Woof · deployed and pre-market
+
+**Status: running, pre-market.** This is the exact wording the site uses, deliberately: deployed is true, commercial is not.
+
+## What the artefact is
+
+A tag system for lost property. A tag carries a QR code and an RFID identity; whoever finds the item resolves the tag and the owner is contacted. The system is running and being deployed now.
+
+## What it proves
+
+That a product can be taken into the field before it is monetised, and that the honest label for that state exists. The distinction matters on a CV because the alternative — calling a pre-launch product commercial — is the kind of claim a technical interviewer unpicks in one question.
+
+## Limits stated on the page
+
+No customers, no revenue and no launch date are claimed. The metric recorded here is a zero on purpose.
+
+## When it is delivered
+
+The tag and resolve-flow photographs land in Phase 7 if Sam chooses to publish them. Product name and description are approved; commercial framing is not.
