22-spike Spike 6 ADD-2 T-NEW tensions sweep CLOSED 2026-05-03
Outcome
outcome-VALIDATED on strict reading per refined-prompt v3.8 (Candidate 6 PLAN-FILE PRE-RESOLUTION promoted to LOCKED). Kill-condition NOT-MET: 15 T-NEW candidates surfaced (kill-condition was 0 tensions across all 17+ spike outcomes; 0 would have been suspicious — 15 within plan §4 Task 6 budget of 5-15).
What was swept
Source-row inventory (26 T-files + 6 cumulative-state + arch-state §§ + Tier 2):
- 12 ε.ι T-files (S1, S2, S2.5, S2.6, S2.9, S2.10, S3, S4, S5, S6, S7, S8) at
~/off-github/library/projects/inherit/T-spike-eps-iota-*.md - 14 22-spike T-files (12 from dispatch inventory + 2 newly-found by parallel sessions): refined-prompt-v3.7 / mq-meta-q-status-review / phase-2-angles / zeta-q5 / zeta-q15 / rt214 / rt216 / rt218 / rt210-212 / vpc-peering / q016 / q017 + S6a-inherit-v2-merged-owl + S213-S217-pin-yaml-and-sssom-rows
- 6 cumulative-state docs at
~/off-github/library/projects/inherit/*-cumulative-state-2026-05-02.md - Tier 2 pgvector library index T-file
- arch-state §11/§12/§13/§14 + §4 amendment registry partial verification

15 T-NEW candidates — disposition
5 PROMOTE-TO-A-N at Rich-adjudication time (pre-staged at A-143..A-147 in T-file body §4):
| A-N | Topic | Tier-pair | Cost-row |
|---|---|---|---|
| A-143 | Faith-tradition Phase-1.5+ wave-per-pillar (vs current Phase-1 commitment) | T1↔T2↔T3 cross-cutting | -£240-450K/yr if approved (5 pillars × £80-150K each Phase-1.5+ deferred) |
| A-144 | VC issuance 2-stage: Phase-1 partner-firm-DID + Phase-1.5+ testator-DID at SI commencement | T1↔T2↔T3 | Combine with A-133 Will-VC-issuance-pattern pre-staged at S5 closure |
| A-145 | G-IRI-VERIFY allow-list lifecycle codification at A-130 (BFO 2020 PURL-flakies) | T1 (CI gate authorability) | Documentation-only |
| A-146 | Multi-jurisdiction-customer Will-update + trigger fan-out Year-2+ defer | T1↔T2↔T3 | -£40-80K/yr Phase-1 if approved (conflict-of-laws engine deferred) |
| A-147 | SSSOM 1.1 spec-evolution reconsideration trigger (curation_rule forward-incompatibility) | T1↔T2 | Combine with A-131 ε.ι formal landing at Q-005 lock-time; ~£500/~1d down-rev cost if 1.1 retires curation_rule |
1 ALREADY-ABSORBED at A-99/A-100/A-101 lock 2026-04-26:
- T-NEW-S6-05 Texas + Florida + RON terminology drift in Q-015 caveat #11 + Q-016 caveat #5 (both misframe Texas+Florida as “Phase-1.5+” when A-99 already locks them as Phase-1; Phase-1.5+ framing is for cantonal-Erbenbescheinigung-equivalents and additional state-level US jurisdictions BEYOND Texas + Florida). Surface-for-Rich at Q-015/Q-016 lock-time as terminology consistency check.
1 PROMOTE-TO-R-NEW for Spike 7 risk register update v1.2:
- T-NEW-S6-12 Hindu pillar cultural-alignment risk MEDIUM-HIGH (T49 evidence; £80-150K/yr per pillar run-rate). Spike 7 should ALSO inspect S6-14 (SSSOM 1.1 forward-incompatibility) + S6-03 (G-IRI-VERIFY allow-list) for additional R-NEW promotion candidates.
8 DOCUMENTED-NOT-PROMOTED as operational follow-on / non-load-bearing for arch-state lock:
- S6-06 LinkML annotation surface separation (covered by
feedback_linkml_annotation_surface_separation) - S6-07 Cedar 4.10 DateTime workaround via Long epoch_days (richard-task #220 Catala-side)
- S6-08 G-CCO-OWL-LOAD Phase-1.5 candidate (operational discipline)
- S6-09 i-ζ:FinancialInstrument collision with cco:FinancialInstrument (covered by ω.η Q-004 + Q-003 locks)
- S6-10 Postgres provisioning blocker (admin-debt; richard-task #209 covers)
- S6-11 bge-small-en-v1.5 multi-language gap Year-2+ (richard-task candidate)
- S6-13 Plan-defect detection rate ~55% per spike (methodological evidence supporting v3.7 → v3.8 Candidate 6 LOCKED — already promoted)
- S6-15 Anthropic Managed Agents pricing reconsideration (covered by S18 4-trigger framework)
Tier-pair pattern + root cause
Dominant tier-pair: T1↔T2↔T3 cross-cutting on jurisdiction scope (S6-01 + S6-02 + S6-04). Secondary T1 commitments on alignment-axiom + CI gates (S6-03 + S6-14).
Most-recurring root cause (3 distinct spike outcomes converge on it): faith-tradition Phase-1 vs Phase-1.5+ scope tension:
- S5 ζ-Q15 directly via T49 cultural-alignment risk MEDIUM-HIGH for Hindu pillar £80-150K/yr per pillar
- S22 Q-017 trigger-event detection partial coverage gap for civil-registry triggers Year-2+ across faith jurisdictions
- S21 Q-016 Will-update faith-tradition witness-pattern-mapping (Islamic two-male / Hindu pandit-presence / Jewish two-kosher-witness)
Single largest cost-row impact lever: T-NEW-S6-01 (faith-tradition Phase-1.5+ wave-per-pillar) + T-NEW-S6-04 (multi-jurisdiction-customer fan-out Year-2+ defer) approved together at Q-015/Q-016/Q-017 lock-time would reduce Phase-1 by ~£280-530K/yr; aligns with #220 E&W IHT SCOPE-DOWN narrowing-but-deepening for first-mover positioning capture.
Plan-defect detection (v3.8-LOCKED Candidate 6 PRE-RESOLUTION)
Plan §4 Task 6: zero defects detected. 4th post-Spike-1 run with zero defects (after Spikes 1, 10, 12, 18, 21, 22 also clean). Detection-rate update: ~55% across Spikes 2-22 closures so far (5 detected of 11 closed: Spikes 2 + 3 + 4 + 8 + 9; 6 zero-defect: Spikes 1, 6, 10, 12, 18, 21, 22).
T-NEW-S6-13 documented-not-promoted as methodological evidence supporting Candidate 6 LOCKED in v3.8 (already promoted by parallel session same day).
Reconsideration triggers preserved (T-file §8)
- A-143 — 5y partner-firm cultural-alignment evidence accumulates (Hindu / Sikh / Jewish / Islamic / Buddhist 5 pillars; success → Phase-1 re-table)
- A-144 — Law Commission Modernising Wills Law 2025 enabling-power SI commencement → testator-facing electronic Will execution becomes legally valid → λ.ε standalone re-tabled
- A-145 — BFO 2020 PURL fix upstream OR allow-list grows >5% of total IRI universe → revisit categorisation
- A-146 — 5-firm Phase-1 pilot multi-jurisdiction case-rate >5% of estate-volume → conflict-of-laws engine pull-forward to Phase-1.5
- A-147 — SSSOM 1.1 final spec publication → curation_rule upstream stable / retired determines κ.δ ★ vs κ.γ down-rev

Methodological observations
- 13th spike of 22-spike suite to close (after Spikes 1+12+18+22+2+21+3+8+9+10+4+5)
- FIRST architectural-debt closure spike (Group 3 Spike 6 of Batch C; Spike 7 risk register update STRICT-AFTER same Batch C session inline per plan §4 strict-order)
- Parallel session DISCOVERED 2 additional T-files (S6a-inherit-v2-merged-owl + S213-S217-pin-yaml-and-sssom-rows) added during the session — subagent’s count of 14 22-spike T-files reflects this; my dispatch prompt’s count of 12 was stale within ~1h
- Pin-drift hook —fix encountered known nested-paren bug at long-form arch-state lastmod prose; manually rewrote both floor-pins (arch-state v3.39 + refined-prompt v3.8) to canonical clean form
"vX.Y (YYYY-MM-DDThh:mm)"per parent CLAUDE.md §6 - Candidate 6 LOCKED in v3.8 by parallel session same day (independent of this Spike); my Spike 6 closure pin-bumped refined-prompt floor v3.7 → v3.8 to reflect locked discipline
- Spike 7 R-NEW substrate ready at T-NEW-S6-12 (Hindu pillar) + S6-14 (SSSOM 1.1) + S6-03 (G-IRI-VERIFY) for Spike 7 risk register update next inline this Batch C session
