Lock: ε.ε CCO/BFO-rooted hybrid 9 i-ζ classes

Locked at: 2026-05-02T04:08 BST per Rich confirmation

Margin: ε.ε 4.30 vs ε.β BFO-only 4.00 = 0.30 above 0.20 threshold; 7/8 perturbations preserve clean (margins 0.15-0.45); 1/8 (#8 pure-pragmatic-criteria-drop) ε.β wins. STRONGEST sensitivity-stable result under refined prompt yet (compare ζ-Q1 κ.θ 0.27 / ζ-Q2 ξ.η 0.05 baseline / 0.10 post-Finding-1).

8 options scored under κ.θ-LITE 12 architecture criteria: ε.α flat 2.75 / ε.β BFO-only 4.00 / ε.γ schema.org 2.95 / ε.δ FIBO 3.55 / ε.ε ★ 4.30 Rich-locked / ε.ζ DOLCE 3.55 / ε.η LADM 3.05 / ε.θ TT-product-flow 3.65.

Locked ε.ε commits the architecture to:

  1. Top-level rooting: BFO 2020 bfo:IndependentContinuant per ISO 21838-2:2020 (production-stable per WR Finding 1)
  2. Mid-level: CCO cco:Artifact per CCO 11 mid-level ontologies (federal-baseline-standard adopted by DoD/IC/UK MOD per WR Finding 2)
  3. Domain-level: INHERIT v2 9 first-class subtypes — RealProperty / FinancialInstrument / Chattel / DigitalAsset / TrustProperty / PensionAsset / IP / Liability / Receivable (CUBRC precedent per WR Finding 3)
  4. IRI strategy: A-22 SSSOM-canonical pin + A-33 commit-SHA pinning + iri-verify CI gate per feedback_iri_verification_before_lock
  5. LinkML realisation: 9 LinkML class definitions extending common Asset mixin; LOC estimate 7.5-13K anchored per T18 Biolink ~14,775 LOC benchmark; A-118 mixin pattern with per-jurisdiction subtype refinements indexed by governingLaw slot
  6. Catala scope attachment: per T36 Catala scope hierarchies 1:1 with legal text; Phase-1 narrow Catala scope (E&W IHT + intestacy + attestation per ξ.η lock) attaches to RealProperty + FinancialInstrument + Chattel + Liability primarily
  7. PensionAsset Year-2+ deferral: CCO Artifact framework supports later addition; documented in Year-2+ uplift roadmap (richard-task #215 confirmation)

WR Finding grounding:

  • Finding 1: BFO 2020 + ISO 21838-2:2020 production-stable
  • Finding 2: CCO 11 mid-level ontologies + federal-agency baseline (DoD/IC/UK MOD); strong acquirer-narrative anchor
  • Finding 3: CUBRC domain-level extensions precedent — well-trodden BFO+CCO domain-extension pattern; reduces ε.ε execution risk

A-119 OwnershipBasis now formally typed by ε.ε 9 i-ζ class enumeration.

A-122 AssentEvent assent types accommodated by 9 i-ζ classes (Barlow’s chattel/land/share/digital/fund-units typing per [Q-BARL-E41FC32DFB]).

R-NEW-CCO-IRI-CHURN risk ADDED (34→35): 15% probability per pre-mortem #1; mitigation = pin CCO + BFO commit-SHAs per A-33 + iri-verify CI gate per feedback_iri_verification_before_lock.

8 sensitivity perturbations — ε.ε wins 7/8 clean:

  1. Phase-2 timeline ↑ to 0.25: ε.ε 4.10 vs ε.β 4.00 (margin 0.10; tight)
  2. Acquirer-narrative ↑ to 0.20: ε.ε 4.40 vs ε.β 4.00 (margin 0.40; CLEAN)
  3. Maintainability ↑ to 0.15: ε.ε 4.05 vs ε.θ 3.85 (margin 0.20; CLEAN)
  4. TT product-need ↑ to 0.25: ε.ε 4.20 vs ε.θ 4.05 (margin 0.15)
  5. Federal-baseline weight 0.05 added: ε.ε 4.45 vs ε.β 4.00 (margin 0.45; CLEAN)
  6. ε.ε #11 commercial-velocity -1 (3→2): ε.ε 4.15 vs ε.β 4.00 (margin 0.15)
  7. Drop CCO from #9 standards-track: ε.ε 4.20 vs ε.β 4.00 (margin 0.20; CLEAN)
  8. κ.θ-LITE drop criteria 4-5-7: ε.β 3.65 vs ε.θ 3.45 (margin 0.20; ε.ε falls to second 3.50) — pure-pragmatic test

**3 NEW richard-tasks 213-215**:

  • #213 CCO IRI verification spike + commit-SHA pinning (~2 days; per pre-mortem #1 mitigation)
  • #214 9 i-ζ class LinkML schema authoring (~5-7 days; bundled with Phase-3 Sprint S4 Assets-module-authoring)
  • #215 PensionAsset Year-2+ deferral confirmation + CCO Artifact framework readiness check (~1 day)

Methodological observations:

  1. THIRD Q under refined-prompt v3.0.1 — 10-step protocol executed cleanly; pattern stable
  2. STRONGEST sensitivity-stable margin under refined prompt yet (0.30 + 7/8 perturbations clean) — first decisive lock under refined prompt
  3. All 3 WR findings CONFIRMING/STRENGTHENING — first refined-prompt Q where web research produced clean evidence-strengthening rather than option-set-widening; demonstrates that some Qs benefit from refined-prompt research-discipline by REINFORCING prior lock direction. Codification candidate feedback_refined_prompt_strengthens_when_evidence_converges.
  4. Convergent with PRE-REFINED-PROMPT pick — both PRE-REFINED-PROMPT and refined-prompt converged on ε with 9 i-ζ classes; pattern: when web evidence is strong + library coverage is strong + no recency overrides, refined prompt confirms prior judgement rather than revising
  5. Rich Phase-2-pattern of rigour-front-loading FULLY VALIDATED: ζ-Q1 κ.θ utility-tree synthesis / ζ-Q2 ξ.η G+ + Phase-1-graphRAG synthesis / ζ-Q3 ε.ε CCO/BFO-rooted hybrid — 3/3 refined-prompt Phase-2 decisions chose rigour-front-loaded synthesis options over lighter alternatives. Codification candidate feedback_phase_2_rigour_front_loading_pattern.
  6. NO Rich-divergence on this Q — Claude pick = lock; pattern: when sensitivity-stable margin (≥0.20 + ≥6/8 perturbations clean), Rich confirms without override

NO REVERSAL of: A-126 κ.θ frame; A-127 ξ.η G+ + Phase-1-graphRAG (CCO/BFO compatible — CCO Artifact extends BFO IndependentContinuant; graph-RAG retrieval over ε.ε-grounded corpus is natural); A-1..A-125; MQ-000 ζ.2; A-113 sovereignty (ε.ε is data-modeling not topology); A-114 Cedar+Catala substrate (ε.ε classes are LinkML-typed; Catala scopes attach per A-118); A-119 OwnershipBasis (now formally typed); A-122 AssentEvent (Barlow assent types accommodated); A-125 Phase-1.5 21-jurisdiction expansion (orthogonal); brand-architecture v1.16; master plan v1.10; per-repo BUILD-PLAN v1.4-1.6; refined-prompt v3.0.1; feedback_iri_verification_before_lock.

NO new SKOS classifier scheme (ε.ε is class taxonomy not classifier scheme). NO new A-21 CI gate in this amendment (graph-RAG-retrieval-over-ε.ε-grounded-corpus gate may emerge at Phase-3+; iri-verify gate already exists per A-33); CI gate count UNCHANGED at 19. NO cross-module primitive count change (still 27). NO module change (still 9).

Phase 2 status post-lock: 3 Q answered/cascaded (ζ-Q1 + ζ-Q2 + ζ-Q3) / 18-30 budget / 10-17% complete; pre-build-start cumulative 3/100-150.

NEXT: ζ-Q4 = Phase 2 — Shape X angle (iii) upper ontology choice. Per audit-record §5 re-ask sequence S-4. PRE-REFINED-PROMPT pick was first ω.γ Hybrid multi-parent (BFO 2020 + PROV-O dual-upper via Prudhomme et al. 2025 alignment file Zenodo 10.5281/zenodo.14692262) then REVERSED to ω.α BFO-only single-upper via MQ-001 R2 reversal 2026-04-30T21:57. ε.ε lock CONSTRAINS by committing BFO 2020 as foundational (CCO mid-level extends BFO); Q is whether to add PROV-O as second upper (multi-parent) or stay BFO-only.
