Q-023 LOCKED ω̃.ι ★ — Catala Phase-1.5+ formal-verification activation-trigger META-Q (constrained-bold-synthesis) 2026-05-05
Lock summary
Locked option: ω̃.ι ★ constrained-bold-synthesis. Locked 2026-05-05T09:08 BST per Rich approval “lock ω̃.ι - now use refined-end-of-turn-directive.md to display the next question”. A-163 amendment arch-state v3.57 → v3.58 §4 lastmod-prose. FIRST v3.12 production use validated.
Components (5+ Day-1 patterns composed)
- Q-002 ξ.+ baseline preserved — Phase-1 Catala formal-verification test-suite + Cedar Analysis + standards-track Phase-1 (per A-130)
- Q-019 ε.ζ baseline preserved — Catala WillAuthoringReview/WillUpdateReview/WillCredentialReview on-publish CI-time
- richard-task #220 SCOPE-DOWN respected — Phase-1 = E&W IHT main rules ~6-12 statutes (NRB s.7 + TNRB s.8A-8C + RNRB tapering s.8D + s.8FA + chargeable transfer s.3 + main rate s.7(1) + charity rate Sch 1A); 25-statute extension Phase-1.5+ trigger T3 (acquirer-DD-asks event)
- T57 5-tier verification-scope §carve-out:
- typecheck HARD (Phase-1)
- clerk-test HARD (Phase-1)
- 6-12 statute golden vectors HARD (Phase-1; 6/6 HMRC F1=1.000 per cumulative-state-2026-05-02)
- Mopsa-on-date-sensitive SOFT warn-not-block during upstreaming (Phase-1)
- PBT-subset SOFT (Phase-1)
- NONE F-extracted* — explicit non-claim per T57 “INHERIT rules NOT F*-verified end-to-end”
- Mopsa-Phase-1-SOFT separate-tool against Catala output (Mopsa+Catala upstreaming “in-progress” 2026-04 per T57)
- Rocq vendor-badge Day-1 cite — InheritKit assurance Day-1 cites “Catala compiler carries Rocq small-step semantics mechanisation (4,261+2,846 LOC, 527 commits, 1-min re-verify per CatalaLang/catala-formalization)”; explicit non-claim “INHERIT rule corpus is Rocq-mechanised”
- F compiler-only badge Day-1 cite* — InheritKit assurance Day-1 cites “Catala compiler carries F*-mechanised translation correctness (POPL 2021; ~3500 LOC proof on ~100 LOC compiler step)”; explicit non-claim per T57
- 5-criteria composite Phase-1.5+ activation trigger per v3.12 #9 3-field codification:
- T1 Mopsa+Catala upstreaming releases stable (monthly Phase-1 review Rich+Paul; arch-state amendment + master-plan §15)
- T2 ≥1 actionable counter-example hint observed Phase-1 production (quarterly Phase-1 review Rich+Paul+partner-firm-pilot-lead; arch-state §13 + acquirer-DD §3)
- T3 partner-firm DD asks for “all 25 statutes verified” (per-DD-engagement Rich+acquirer-DD-team-lead; richard-task #220 promote-to-FULL + master-plan §15)
- T4 cross-jurisdiction Phase-1.5+ wave starts event-anchored to Q-015 λ.η wave-per-jurisdiction (event-anchored; Rich+Paul; arch-state §13 + per-jurisdiction Catala spec)
- T5 Catala team upstreams faith-tradition primitives R-029 positive trigger (quarterly Catala-team Zulip + GitHub monitor Rich; arch-state amendment + R-029 status update)
- Cross-jurisdiction wave alignment Q-015 λ.η — Catala cross-jurisdiction expansion event-anchored to Q-015 λ.η Phase-1.5+ wave-per-jurisdiction (Scotland / Switzerland / Texas / Florida / Hindu / Muslim / Jewish per A-115)

Score-frame
- Wsum 4.79 unweighted margin 0.50 ROBUST over ω̃.ε runner-up 4.29 (above 0.20 robust threshold)
- 7/8 perturbations favour ω̃.ι ★
- Perturbation #4 c6 ÷2 (symmetric ÷2 on most-relied-on per v3.12 #3) reveals c6 (cross-jurisdiction Q-015 λ.η integration) drives 60% of margin → flag
over-reliance-detectedLIGHT JUSTIFIED (Q-015 integration is acquirer-DD-binding substrate-derived, not pattern-matching) - Perturbation #8 — A-25 stress-test forcing 25-statute Phase-1 — flips to ω̃.θ; NOT the case under richard-task #220 SCOPE-DOWN
Cost rows (R3a/R3b split per v3.12 #8)
- R1 build £3-5K
- R2 timeline +0.5-1mo
- R3a Y1 ramp £1-2K/yr
- R3b Y2+ steady-state £0.2-0.5K/yr
- R4 Y2+ uplift £10-15K
- R5 5y cumulative no-uplift £5-8K
- R6 5y acquirer-ready £15-23K — LOWEST among options scoring >4.0; bold-synthesis pays for itself within Year-1 via lower R4 acquirer-DD-uplift cost
Reversal cost (v3.12 reversal-cost realism guard)
ω̃.ι ★ → ω̃.ε degrade cost 1-2 weeks (NOT “3-5 days”) — factors deployed Phase-1 Mopsa-CI-pipeline removal + acquirer-DD §3 commitments staked + partner-firm SDK consumer impacts (Mopsa output surface).
v3.12 FIRST production use compliance
- HARD PRE-FLIGHT PASS (Tier-2 pgvector 10 chunks sim 0.779-0.804 + 5 web tracks + T57 + cumulative-state read)
- step 4d OPTION COMMITMENT CLASSIFICATION applied
- symmetric ÷2 perturbation on most-relied-on c6 (#4)
- R3a/R3b cost split
- 11 sub_clarifications_locked
- N≥5 counter-pattern check explicit (yielded CONSTRAINED-bold-synthesis)
- Phase-N+1 trigger 3-field codification across all 5 trigger criteria (no
incomplete-trigger-specflags)
Substrate-correcting findings (per v3.11 Harvard-depth uniform default)
- Catala still PoC at DGFiP 2026 (Web track a) — not yet production at French tax authorities; DGFiP transitioning to Mlang. Phase-1.5+ trigger T1 “Mopsa+Catala upstreaming releases stable” substrate-corrects this risk
- UK Wills SI commencement timeline (Web track e) — far longer than government-response-on-16-May (T-11 days from now); Bill → Parliament → Royal Assent → secondary legislation → commencement. Cross-jurisdiction wave T4 trigger event-anchored to Q-015 λ.η wave lifecycle absorbs this
- Mopsa+Catala upstreaming “in-progress” as of T57 lastmod 2026-04 — Phase-1-Mopsa-soft-as-separate-tool is the bridge until upstream lands
- T57 explicit warning “INHERIT v2 is formally verified” claim must NOT leak into marketing; sub_clarifications_locked.fstar_compiler_only_badge_day_1_cite carves explicit non-claim
2 NEW richard-tasks (lock-DEFERABLE Phase-1 spikes)
- S1 Mopsa-on-INHERIT-rules micro-spike (~3-5d) — validates ESOP 2024 16-bugs result reproduces on INHERIT-rule corpus; protects against ω̃.ι ★ Mopsa-soft → ω̃.δ degrade
- D1 25-statute Catala extension cost benchmark (~½-1d) — sanity-check trigger T3 cost-realism band; extrapolated from S4+S8 statute-time-cost ratios
Pattern observations
- FIFTEENTH refined-prompt-era ζ.2 lock outside Group 1 (Q-005 + Q-006..Q-015 + Q-019 + Q-021 + Q-022 + Q-023)
- FOURTEENTH consecutive bold-synthesis substrate-architectural lock with explicit N≥5 counter-pattern check confirming Mopsa-Phase-1 substrate-derived (T57 ESOP 2024 16-bugs + 6/6 HMRC F1=1.000) but 25-statute / PBT-HARD aspiration-derived → trigger-deferred = CONSTRAINED bold-synthesis (composes 5+ patterns Day-1 while RESPECTING Phase-FIT step 4d + richard-task #220 SCOPE-DOWN)
