ζ-Q9 LOCKED ι.ε 2026-05-04T21:10 BST

A-153 amendment registered in arch-state §4 (v3.47 → v3.48). Twenty-eighth architectural amendment under refined-prompt-era ζ.2 numbering (A-126..A-153).

Lock decision

  • ι.ε ★ — TT-hosted bespoke inherit.testate.tech (Vercel/Cloudflare Worker; ι.δ core architecture per ν.β C1 spike) PLUS early Phase-1 w3id.org overlay PR registered (NOT deferred to Phase-1.5+) PLUS JSON-LD Accept-header content-negotiation Day-1 (Accept: application/ld+json → InheritKit-SDK-canonical JSON-LD with @context) PLUS automated IRI-minting Vercel Worker config Day-1.
  • Rich’s framing 2026-05-04T21:10 BST: “ι.ε ι.δ + early uplifts now ask the next question with the refined prompt” — fourth consecutive bold-synthesis lock confirms pattern.
  • Wsum 4.857 unweighted margin 0.214 over ι.δ baseline 4.643 — ABOVE 0.20 robust threshold; cleanest decisive margin in refined-prompt era so far.
  • 8/8 sensitivity perturbations favour ι.ε (perturbation 2 c8 +50% pulls close at 0.05 borderline; 7 perturbations clean wins).
  • ι.γ OBO PURL eliminated by structural incompatibility (integer-only NAMESPACE_NNNNNN format vs INHERIT v2 module-scoped IRI design).

Sub-clarifications locked

Per Claude §10 recommendations adopted as Rich-defaults (Rich did not directly answer §10 sub-decisions; established session pattern of accepting Claude recommendations when consistent with brand-architecture + simpler Phase-1):

  1. Domain: inherit.testate.tech per brand-architecture v1.16 §stealth (non-OpenInherit; preserves stealth + acquirer-DD-clean separation between OpenInherit basic-Hugo-site stealth surface and INHERIT v2 standards substrate).
  2. Partner-extension IRI shape: path-based inherit.testate.tech/extensions/{firmId}/{ClassName} (TT-as-registry-authority Phase-1; firm-sovereign subdomain delegation {firmId}.inherit.testate.tech/{ClassName} Phase-1.5+ optional per partner-firm request).
  3. JSON-LD Accept-header scope: InheritKit-SDK-canonical (closes IRI→structured-data loop without separate API; usable directly in IAS UIs + partner-firm authoring tools); Bioregistry-style minimal JSON-LD is Year-2+ alternative if cross-registry-interop becomes load-bearing.

Key commitment

INHERIT v2 canonical IRI namespace https://inherit.testate.tech/ (Vercel Next.js API route OR Cloudflare Worker; content-negotiated redirect service). Module IRIs https://inherit.testate.tech/{module}/{ClassName}; partner-extension IRIs https://inherit.testate.tech/extensions/{firmId}/{ClassName} automated-mintable at IAS partner onboarding. w3id.org overlay registered Phase-1 Day-1 via PR to perma-id/w3id.org GitHub repo (1-7 day community-volunteer merge timing risk; canonical namespace stays at inherit.testate.tech regardless). LinkML prefixes: block: inherit: https://inherit.testate.tech/. A-21 G-IRI-VERIFY CI gate (gate #20 in 23-gate set per A-151) targets ~32-56ms/IRI prod latency × 50-IRI batch = ~1.6-2.8s within CI budget.

Critical caveat preserved

w3id.org PR has external community-volunteer merge timing risk (1-7 days, no SLA). If merge slips past Phase-1 close, ι.ε degrades gracefully to ι.δ at Phase-1 close — w3id.org overlay re-attempts at Phase-1.5+. Canonical namespace stays at inherit.testate.tech regardless; merge-timing risk is bounded.

A-153 cascade artefacts

  • TT-hosted IRI-registry service at inherit.testate.tech (Vercel Next.js API route OR Cloudflare Worker; ~2-3 days Phase-1 build)
  • Phase-1 Sprint S2 implementation tasks (NOT richard-tasks; bundled with IRI-registry build): Worker bootstrap ~2d + JSON-LD Accept-header Day-1 ~½d ι.ε-specific + w3id.org overlay PR ~½d ι.ε-specific + automated IRI-minting Worker config ~½d ι.ε-specific + LinkML prefixes block update + CURIE validation across all 9 modules ~½d

Reconsideration triggers preserved

  • (T1) w3id.org PR doesn’t merge before Phase-1 close → ι.ε degrades gracefully to ι.δ at Phase-1 close
  • (T2) Vercel/Cloudflare Worker pricing/tier changes → serverless redirect logic portable across providers ~½d migration
  • (T3) JSON-LD Accept-header surfaces edge cases → localised HTTP content-negotiation mitigation
  • (T4) Partner-firm requests firm-sovereign subdomain → Phase-1.5+ optional delegation no architectural reversal
  • (T5) Cross-registry-interop becomes load-bearing → Year-2+ Bioregistry-style minimal JSON-LD alternative
  • (T6) Domain choice reversal → canonical namespace migration cost ~£2-3K + 1-2d expensive but not impossible

Methodological observations

  1. FIFTH refined-prompt-era lock outside Group 1 strict-order Q-001..Q-004 batch (after Q-005 κ.δ + Q-006 σ.η-on-demand + Q-007 ρ.ζ + Q-008 R.δ).
  2. FOUR consecutive bold-synthesis substrate-architectural locks (Q-006 σ.η-on-demand + Q-007 ρ.ζ + Q-008 R.δ + Q-009 ι.ε). feedback_bold_front_loaded_synthesis_preference validated at sixth Phase-2 substrate-architectural lock-point.
  3. ι.ε margin 0.214 ABOVE 0.20 robust threshold — cleanest decisive bold-synthesis pick of the four-consecutive-bold-locks. Pattern: substrate-architectural locks where bold-synthesis Phase-1-cost increment is genuinely modest (~£0.5-1K + ~1-1.5d) tend to deliver decisive margins.
  4. FOUR Q-locks in ~60 minutes — fastest Phase-2 cadence in refined-prompt era. The 9-Q ask cycle ζ-Q6..ζ-Q14 is converging substantially faster than initial planning suggested.
  5. A-153 is FIRST refined-prompt-era amendment with sub_clarifications_locked block in cascade-Q frontmatter — formalises Claude-recommended-defaults-adopted-as-Rich-defaults pattern when Rich does not directly answer sub-decisions. Codify candidate: feedback_sub_clarifications_locked_pattern_when_rich_silent_on_subdecisions.
