ζ-Q15 LOCKED λ.η ★ Wills follow-through 2026-05-05T06:07 BST

Summary

Rich approved λ.η bold-synthesis bundle for Wills follow-through after Harvard-depth research turn surfaced 4 substrate-correcting findings + 17-criterion frame + bold-synthesis upgrade. Margin grew Spike 5 substrate λ.ζ 4.83/0.41 → λ.η 4.88/0.29 ROBUST (uncertainty reduced via Q-005..Q-014 cascade alignment + EUDI ARF v2.8.0 + JOSE/COSE + Render Method + Government response trigger). TENTH consecutive bold-synthesis substrate-architectural lock. Q-015 lock CLOSES Phase 2 architecture-options selection 15 substantive locks. NEXT ζ-Q16 will be FIRST v3.10 production use.

Locked configuration (5 components)

  1. λ.ζ hybrid baseline preserved: canonical-Will-as-canonical-document + WillCredential SD-JWT VC + did:web partner-firm DID + Bitstring Status List v1.0
  2. Q-005..Q-014 cascade alignment Day-1: Q-009 ι.ε IRI shape inherit.testate.tech/wills/credentials/{firmId}/{willId} + Q-013 Δ.η schema.org/Action peer alignment SSSOM rows + Q-014 V5+ ext_inherit_tier + ext_iri_verified_date + Q-008 R.δ BFO:0000023 role-bearer pattern + Q-012 π.ζ P4-Hybrid CrossModuleRef + Q-005 κ.δ all-3-SKOS predicates maturity-graded
  3. Multi-pathway VC securing: SD-JWT VC primary + JOSE/COSE alternative (W3C Rec May 2025) + Data Integrity 1.0 fallback
  4. EUDI ARF v2.8.0 conformance Phase-1 design-doc: ARF §6.3 Attestation Formats + end-of-2026 EU member state deadline + Phase-1.5+ wallet integration trigger
  5. Render Method Phase-1.5+ trigger: pre-staged WillCredential rendering hook; W3C Rec publishing September 2026 (4 months from now)

Sub-clarifications locked (Claude §10 → Rich-defaults)

  • Phase-1 jurisdictional UK&W primary + Scotland + Switzerland; Texas + Florida + RON Phase-1.5+ (Florida Qualified Custodian + vulnerable-adult exception)
  • Phase-1 partner-firm-issued WillCredential; testator-issued Phase-1.5+ at Law Commission SI commencement (T-11 days)
  • Faith-tradition Phase-1.5+ wave per pillar (T49 cultural-alignment risk MEDIUM-HIGH; £80-150K/yr per pillar)
  • Multi-pathway SD-JWT VC primary; JOSE/COSE alternative available not mandatory
  • EUDI ARF v2.8.0 conformance design-doc Phase-1; implementation Phase-1.5+

Score-frame

  • Wsum 4.88 unweighted margin 0.29 over λ.ζ runner-up 4.59 ROBUST above 0.20 threshold
  • Spike 5 substrate λ.ζ provisional 4.83/0.41 → λ.η 4.88/0.29 ROBUST (Harvard-depth uplift)
  • 17-criterion frame extends Q-014 V5+‘s 16: NEW c16 EUDI ARF / W3C VC 2.0 family conformance + c17 Q-005..Q-014 cascade alignment
  • 7/8 sensitivity perturbations favour λ.η
  • Average Wsum across 7 options 3.69 (lifted from Spike 5’s ~3.40 estimate via research-grounded scoring)

Four substrate-correcting findings (Harvard-depth research)

  1. EUDI ARF v1.4 → v2.8.0 advancement (substantial spec evolution; substrate cited only v1.4)
  2. JOSE/COSE securing pathway W3C Rec May 2025 (substrate cited only SD-JWT VC; multi-pathway portability achievable Phase-1)
  3. Render Method Sept 2026 W3C Rec coming (substrate didn’t reference upcoming Recs; pre-staging avoids Phase-1.5+ retrofit)
  4. Government response 16 May 2026 = T-11 days from now (Phase-1.5+ trigger may fire mid-Phase-1 build’s first sprint)

Cascade artefacts

  • arch-state.md v3.53 → v3.54 §4 changelog A-159 row landed
  • INDEX.md v2.20 → v2.21 + asked_so_far stays 15 (Q-015 already counted CURRENT-AWAITING-ANSWER) + answered_so_far 14 → 15 + placeholder_so_far stays 5
  • Q-015 cascade-Q file moved current-questions/Q-015-zeta-wills-follow-through.md → answered-questions/Q-015-zeta-wills-follow-through-locked.md (frontmatter promoted; sub_clarifications_locked block; NEW §11 LOCK DECISION + §12 CHANGELOG body sections)

Phase 2 status post-lock

  • 15 Qs answered (Q-001..Q-015)
  • 0 Qs current pre-formulated
  • 0 Qs missing in re-ask sequence
  • 18-30 Q budget; 15/18-30 = 50-83% complete
  • 9-Q ask cycle ζ-Q6..ζ-Q14 + Q-015 follow-through cycle FULL-CLOSURE
  • Phase 2 architecture-options selection 15 substantive locks COMPLETE — natural inflection point for Phase 2 closure check or continued Phase-2-eligible Q under refined-prompt v3.10

Methodological observations

  1. ELEVENTH refined-prompt-era ζ.2 lock outside Group 1 strict-order Q-001..Q-004 batch
  2. TENTH consecutive bold-synthesis substrate-architectural lock (Q-006 + Q-007 + Q-008 + Q-009 + Q-010 + Q-011 + Q-012 + Q-013 + Q-014 + Q-015)
  3. TEN Q-locks in ~9.95 hours including overnight idle (Q-006 2026-05-04T20:10 → Q-015 2026-05-05T06:07 BST). Active session windows ~17-20 min/lock except Q-013 (~40 min scoping-doc-before-lock pattern) + Q-014 (~30 min Harvard-depth research turn) + Q-015 (~23 min Harvard-depth research turn)
  4. Harvard-depth research pattern validated SECOND time at Q-015 (after Q-014 V5+ first invocation). Codify candidate feedback_harvard_depth_research_resolves_borderline_margin_uncertainty validated TWICE — pattern reliable
  5. Q-015 lock-decision is ARCHITECTURAL CULMINATION of Q-005..Q-014 cascade — λ.η explicitly consumes 6 of the 9 cascade locks (Q-005 + Q-008 + Q-009 + Q-012 + Q-013 + Q-014) Day-1 in Phase-1 implementation tasks
  6. Phase 2 architecture-options selection 15 substantive locks COMPLETE — natural inflection point for Phase 2 closure check
  7. feedback_bold_front_loaded_synthesis_preference validated at eleventh Phase-2 substrate-architectural lock-point

Counters unchanged

  • Cross-module primitive count: 27 (inherit:Will is canonical primitive #28 candidate at Phase-1 implementation OR within-Wills-module domain class — defer numbering decision)
  • A-21 CI gate count: 27 per A-158 (λ.η consumes existing gates #20 G-IRI-VERIFY + #23 G-SKOHUB-SHACL-VALIDATE + #26 G-SSSOM-MATURITY-REGEX + #27 G-ROBOT-SSSOM-INJECT; potential future G-WILLCREDENTIAL-VALIDATE Phase-1.5+ candidate)
  • SKOS classifier scheme count: 23
  • Module count: 9
  • Risk register: 38

Reconsideration triggers preserved

  • T1: Government response 16 May 2026 → testator-facing electronic Wills permitted earlier than expected → λ.ε standalone re-tabled; testator-DID issuance ~£5-8K Phase-1.5+ extension
  • T2: EUDI ARF v2.8.0 → v3.x breaking changes pre-end-of-2026 → pin v2.8.0 + ROBOT v3.x conformance migration ~£3-5K
  • T3: Render Method Sept 2026 ships diverging from pre-staged hook → drop pre-staged + re-implement at Phase-1.5+ trigger ~½d
  • T4: JOSE/COSE securing pathway unused by all partners → mark “available but unused”; no rollback
  • T5: Florida Qualified Custodian system Phase-1.5+ requires bespoke architecture → FS §732.524 conformance design-doc Phase-1.5+ ~£3-5K
  • T6: Q-009 ι.ε inherit.testate.tech namespace migration → WillCredential VC IRI migration via Worker config update ~½d
  • T7: Faith-tradition partner-firm onboarding Phase-1.5+ requires Catala module per pillar → £80-150K/yr per pillar wave

NEXT

ζ-Q16 = FIRST v3.10 production use with NEW SPIKE-CANDIDATE SCAN sections (lock-BLOCKING + lock-DEFERABLE per F-spike-loop step 7 sub-bullet). Likely topic: Phase 2 closure check / Phase 3 boundary advance verification given Phase 2 architecture-options selection 15 substantive locks COMPLETE; OR specific gap surfaced from Q-006..Q-015 cascade. Per refined-prompt v3.10 step 5 IDENTIFY GAPS — most relevant + impactful Phase-2 question to ask now.
