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 — A hand-written Nix package with an exit plan
|
||
|
||
**Status: stub.** The whole file is short enough to publish verbatim; it lands in Phase 7.
|
||
|
||
## What the artefact is
|
||
|
||
A package definition for the agent operations console: `fetchurl` against a released artifact with a verified hash, a documented reason for overriding nixpkgs, an `installPhase` that stages the binary, and a comment stating the condition under which the file should be deleted.
|
||
|
||
## What it proves
|
||
|
||
More than knowing Nix exists. The signals are that someone noticed a version gap, fixed it locally instead of waiting, pinned it so the fleet is reproducible, and wrote down when to remove their own patch. Knowing when to delete your own override is the senior part.
|
||
|
||
## When it is delivered
|
||
|
||
Phase 7. The file is in the infrastructure repository; source fact: content spine section 4.2.
