Estate continuation (post-branding): wiki + business case; gated CLADE/ANCHOR reconciliation

[hyperpolymath]

Tracks remaining estate cleanup/docs for ephapax after the merged brand pass (#325) + Canva hero (#326). Feeds the paint-type Project #41 scheduler (DEP-01, the region-calculus core).

Remaining (safe / additive)

• 4-audience wiki: docs/wikis/{Home,Developer,Maintainer,User,Lay-Public,Glossary}.md + README.adoc index; add just wiki-sync. (ephapax already has rich docs — wiki signposts them.)
• Business case: docs/business/{strategy-operations,supply-chain,marketing,finance,governance-legal-risk}/, seeded from 6a2/ECOSYSTEM.a2ml (foundation-language; chain katagoria → ephapax → typed-wasm → PanLL).
• Branding done (Brand pack: amber "exactly-once" mark, social-preview, Marr/Sandler diagrams #325/brand: add Canva symbolic hero + feature on README #326); contractile trident already complete (it's the substrate exemplar) — no work.

GATED — draft PR only, owner decides (identity)

• ephapax has NO CLADE.a2ml — needs an identity declaration (uuid owner-assigned; clade foundation-language per ANCHOR). Identity birth = owner act.
• ANCHOR drift: anchors/ANCHOR.a2ml (clade=unknown) vs 6a2/ANCHOR.a2ml (clade=foundation-language) disagree — reconcile to one.

Already tracked (not duplicated)

• ci: boj-build.yml — malformed curl JSON + dead .local mDNS hostname + http:// estate-policy violation; decide keep or delete #266 (boj-build malformed JSON / dead host), hygiene: .zig-cache-global/ — 376 build-artefact files committed against gitignore rule #267 (zig-cache-global committed artefacts) — hygiene.

Guardrails

Real proofs only (coqc/idris2 --check); no auto licence edits; no gate bypass; sign commits; draft PRs for gated identity items.
