Key result
CEI Minimal Engine yields Poincaré features outside the empirical AR1 boundary in ~60% of Chaos-family substrates.
The 8-dimensional CEI fingerprint successfully predicts synthetic versus non-synthetic family membership of computational substrates, validating the Phase 2 CEI Minimal Engine.
Poincaré features aid pilot substrate classification; extends Phase 2 validation but leaves open clinical translation.
This document constitutes the 93rd DOI of the PHILIA OS research series (Trinity AI Research Team, Konyang University), reporting the confirmatory results of the Phase 2 CEI (C/Excitatory/Inhibitory) Minimal Engine experiment pre-registered at the 92nd DOI (10.5281/zenodo.21127891). Both pre-registered hypotheses are confirmed: H-92-Primary (CONFIRMED): 60% (12/20) of Chaos-family substrates exhibit Poincaré return-map features outside the empirical AR(1) boundary (seq_AC1 < 0 OR SD1/SD2 > 1.0), exceeding the pre-registered ≥50% threshold. The pilot result (Rössler: seq_AC1 = −0.204, SD1/SD2 = 1.230) is precisely replicated. H-92-Secondary (CONFIRMED + ROBUST): The 8D CEI fingerprint provides ΔR² = 0.240 beyond AC1+MSE in hierarchical regression predicting Synthetic vs Non-Synthetic family membership (F(8,177) = 9.30, p ≈ 0), robust to sensitivity analysis (ΔR² = 0.222, n = 148). The CEI Minimal Engine (Port A, production coupling, Wilson-Cowan C/E/I oscillator) was applied to 188 substrates from the SC-13 registry across 10 seeds each (1,880 total engine runs). Engineering Validation Ladder Level 2 is fully passed for the pilot substrate set. The decisive methodological insight — Poincaré return-map features borrowed from 13 years of HRV analysis in exercise physiology — revealed attractor geometry that 2-dimensional projections had concealed. Pre-registration violations: 0. Cumulative self-corrections: 27. Gate-0 adversarial review (Chris / Claude Opus): UNCONDITIONAL PASS (2026-07-03). SHA256: 842afb7ab2ab4dac21134a19bd524d9e9efee483de7089f535cc19c06348a3c3. DOI lineage: 92nd pre-registration (10.5281/zenodo.21127891) → 93rd results (this document). Measurement is life. Description, not proof. Pre-registration protects us. — PHILIA OS | 0∞1∞0.5∞Trinity AI Research Team | Konyang University | July 2026

신두섭 (2026) studied Chaos-family substrates (n=188). CEI Minimal Engine was evaluated on Poincaré return-map features outside the empirical AR(1) boundary (seq_AC1 < 0 OR SD1/SD2 > 1.0). The CEI Minimal Engine demonstrated that 60% of Chaos-family substrates exhibited Poincaré return-map features outside the empirical AR(1) boundary, exceeding the pre-registered ≥50% threshold.
