Q-019 LOCKED ε.ζ ★ cross-tier execution substrate timing 2026-05-05T06:27 BST

Summary

Rich approved ε.ζ bold-synthesis bundle for cross-tier execution substrate timing — fills the Catala timing gap left by Q-013 + Q-015 locks while consuming established Q-006/Q-011/Q-014 patterns Day-1. ELEVENTH consecutive bold-synthesis substrate-architectural lock. FIRST v3.10/v3.11 production use validated.

Locked configuration

ε.ζ Phase-1 baseline (= ε.δ per-substrate-bespoke timing):

Substrate	Phase-1 timing	Empirical evidence
ELK incremental classify	on-edit	3.78ms steady-state (Q-006)
HermiT DL-completeness	on-demand only	Q-006 σ.η-on-demand
pyshacl I3-I5 inline	per-estate online	1.4-95ms (Q-011)
pyshacl I5 Wasiyyah	async audit-job	4800ms batch (Q-011)
ROBOT sssom:inject	Day-1 CI blocking	~1-2s pipeline (Q-014 V5+ #27)
G-SSSOM-MATURITY-REGEX	Day-1 CI warn-not-block	<100ms regex (Q-014 V5+ #26)
Catala WillAuthoringReview	on-publish CI-time	NEW Q-019 ε.ζ commitment
Catala WillUpdateReview	on-publish CI-time	NEW Q-019 ε.ζ commitment
Catala WillCredentialReview	on-publish CI-time	NEW Q-019 ε.ζ commitment

Phase-1.5+ uplift trigger (event-driven):

• ext_inherit_tier discipline matures with empirical false-positive rates proven low
• Spike S1 Catala compile-time benchmark validates on-edit feasibility (<2s warm steady-state)
• Activation: ALL substrates uplift to ε.ε three-tier (on-edit warn + on-publish block + on-approval final per Maturity:Draft/Candidate/Stable discipline)

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

• Catala execution timing on-publish CI-time Phase-1 (NOT on-edit; respects Catala compile-time uncertainty per Spike S1)
• Spike S1 Catala compile-time benchmark deferred to Phase-1 implementation time; lock-DEFERABLE not lock-BLOCKING
• Phase-1.5+ uplift trigger event-driven on Maturity discipline maturation NOT calendar-driven
• ε.ε on-edit warn flip-to-blocking pattern matches Q-014 V5+ G-SSSOM-MATURITY-REGEX warn-not-block → flip-to-blocking
• user-event-anchored preference continues — on-publish IS event-anchored (publish event); not nightly cron

Score-frame

• Wsum 4.94 unweighted margin 0.12 BORDERLINE over ε.δ runner-up 4.82
• Matches Q-007 + Q-008 + Q-012 + Q-013 + Q-015 borderline patterns
• Bold-synthesis preference holds via 10-consecutive-lock pattern Q-006..Q-015
• 6/8 sensitivity perturbations favour ε.ζ
• 17-criterion frame consistent with Q-014 V5+ + Q-015 λ.η scoring; average Wsum across 7 options 4.05

FIRST v3.10/v3.11 production use validated

v3.11 disciplines applied:

• ✅ Harvard-depth uniform default (no escalation triggers; baseline)
• ✅ Step 7 SPIKE-CANDIDATE SCAN sections (NEW per F-spike-loop v3.10)
• ✅ Spike S1 Catala compile-time benchmark (lock-DEFERABLE; not lock-BLOCKING since ε.δ baseline robust without S1 evidence; protects against ε.ε Phase-1.5+ uplift speculation)
• ✅ Spike D1 pyshacl I5 async-job production-scale (lock-DEFERABLE; refines Q-011)
• ✅ Spike D2 ROBOT sssom:inject CI time (lock-DEFERABLE; refines Q-014)
• ✅ 7-field bootstrap prompt skeletons (Goal / Triggered by / Substrate to read first / Method / Kill condition / Closure cascade / On completion)
• ✅ Binary classification (lock-BLOCKING vs lock-DEFERABLE)

Cascade artefacts

• arch-state.md v3.54 → v3.55 §4 changelog A-160 row landed
• INDEX.md v2.21 → v2.22 + asked_so_far 15 → 16 + answered_so_far 15 → 16 + placeholder_so_far stays 5
• Q-019 cascade-Q file authored at answered-questions/Q-019-zeta-cross-tier-execution-substrate-timing-locked.md NEW (not graduated from Q-NU placeholder; framed fresh under refined-prompt v3.11)

Numbering correction

Prior framing in Q-015 lock-cascade response 2026-05-05T06:13 BST labeled this question “ζ-Q16”. However Q-016 was already LOCKED μ.ε ★ hybrid per Spike 21 of 22-spike suite (Will Update Architecture). Correct Q-number is Q-019 (next available after Q-016/Q-017/Q-018). ε.ζ option lock unchanged.

Pattern observation: parallel-session forthcoming-Q-formulation locks (Spike 21 Q-016 + Spike 22 Q-017 + D5 Q-018) consume Q-numbers ahead of natural-sequence locks; future natural-sequence locks must check Q-number availability before assigning.

Phase 2 status post-lock

• 16 Qs answered (Q-001..Q-015 + Q-019)
• 0 Qs current pre-formulated
• 0 Qs missing in re-ask sequence
• 18-30 Q budget; 16/18-30 = 53-89% complete
• Cross-tier execution substrate timing CULMINATES Q-006..Q-015 cascade — ε.ζ explicitly consumes 5 prior cascade locks Day-1

Methodological observations

1. TWELFTH refined-prompt-era ζ.2 lock outside Group 1 strict-order Q-001..Q-004 batch
2. ELEVENTH consecutive bold-synthesis substrate-architectural lock
3. ELEVEN Q-locks in ~10.3 hours (Q-006 2026-05-04T20:10 → Q-019 2026-05-05T06:27 BST including overnight idle)
4. FIRST v3.10/v3.11 production use validated — SPIKE-CANDIDATE SCAN sections + 7-field bootstrap prompt skeletons + Harvard-depth uniform default
5. Numbering correction documented — parallel-session Q-number consumption pattern surfaced
6. ε.ζ explicitly consumes 5 prior cascade locks Day-1 (Q-006 + Q-011 + Q-014 + Q-015 + user-event-anchored preference)
7. feedback_bold_front_loaded_synthesis_preference validated at twelfth Phase-2 substrate-architectural lock-point

Counters unchanged

• Cross-module primitive count: 27
• A-21 CI gate count: 27 (ε.ζ consumes existing 20-27)
• SKOS classifier scheme count: 23
• Module count: 9
• Risk register: 38

Reconsideration triggers preserved

• T1: Catala compile-time >5s on production schema → ε.ε option retracted; ε.ζ degrades to ε.δ clean down-rev
• T2: pyshacl I5 async-job >60s production-scale → async-job cadence policy review Phase-1.5+ extension ~£3-5K
• T3: ROBOT sssom:inject CI time >60s/run → cache + warm JVM + nightly cadence ~½d Phase-1.5+
• T4: Catala-LinkML scope-binding regression 1.1.0 → 1.2.0 → pin 1.1.0 + upgrade compat test
• T5: IAS authoring UX research reveals on-publish Catala feedback too slow → Phase-1.5+ uplift trigger to ε.ε on-edit warn
• T6: EUDI ARF v2.8.0 → v3.x changes WillCredential schema affecting Catala → schema version pin + migration spike

NEXT

Q-020 = next Phase-2-eligible question per refined-prompt v3.11 step 5 IDENTIFY GAPS. Phase 2 architecture-options selection 16 substantive locks COMPLETE — natural inflection point for Phase 2 closure check OR continued Phase-2-eligible Q. Likely: Phase 2 closure check / Phase 3 boundary advance verification at 16/18-30 = 53-89% complete inflection point. v3.11 Harvard-depth uniform default + SPIKE-CANDIDATE SCAN sections required.
