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 — Non-IT working history
+
+**Status: stub for the visual treatment.** The roles are final; the presentation lands in Phase 7.
+
+## The roles
+
+| Role | Where | What it involved |
+|---|---|---|
+| Chalet chef | Merribel, France | Meals for chalet guests, kitchen operations, menu planning, dietary requirements, in a high-pressure alpine season |
+| Wine waiter | South Australia and Victoria | Premium wine regions, varietals, food pairing |
+| Horseback tour guide | Victorian high country | Guided tours, rider safety, horse welfare, trail navigation |
+| Stable construction | Mount Beauty, Victoria | A 24-bay stable build — project management, budgeting, hands-on construction |
+| Civil servant | Victorian State Government, Melbourne | Administrative and operational support to state-level programs |
+| Horse trainer and stable hand | Sunbury, Victoria | Care and training of thoroughbreds, exercise, grooming, race-day preparation |
+
+## What it proves
+
+That the engineering sits on a wider working life. Kitchen service and production incidents share a shape; guiding strangers on horses in the high country is risk management with consequences; a stable build is a budget and a schedule held by hand. These are the reasons the technical pages read as practical rather than academic.
+
+## Why this is on a technical site
+
+Because leaving it out would make the career look narrower than it is, and because the years it occupies are otherwise unexplained.
+
+## Coverage limit
+
+Descriptions are limited to what the résumé and the evidence notes corroborate. Roles, employers' towns and the type of work are stated; no employer is named beyond the region, and no claim is made about scale, revenue or headcount that the sources do not carry.
