This preregistration document establishes a blind prediction protocol to validate PHISCORE = Hₙorm × (1−AC1) as a substrate classifier for the PHILIA Phase Vector z-coordinate. Background: During v32 Substrate Exploration (2026. 05. 24), PHISCORE was discovered as a strong rank predictor of the PHILIA z-coordinate (Spearman ρ=0. 886, n=6). Shannon entropy alone failed (ρ=0. 086) ; the independence factor (1−AC1) is the critical component. Physical interpretation: PHISCORE measures the effective novelty exposure experienced by neurons. Design: n=29 substrates (6 existing zᵣef frozen + 16 new real-world + 7 synthetic). PHISCORE values frozen at 2026-05-25T14: 55: 02 before v32 ablation execution. Thresholds frozen: THRHIGH=0. 35 / THRLOW=0. 20. Primary hypothesis (H-SC1-1): Spearman ρ ≥ 0. 85 → Classifier promotion. Secondary hypothesis (H-SC1-2): log-return PHISCORE > level PHISCORE for all 7 financial assets. Tertiary hypothesis (H-SC1-3): AR (1) φ-sweep monotonicity confirmed. Power (n=29, ρ=0. 85): >0. 999. Effective n=23. 2 (ICC=0. 7 conservative correction). 5-AI adversarial review: 판도라 → 루카스 → 크리스 (Gate-0 v7, 9 rounds, UNCONDITIONAL ACCEPT) → 서생 → 선비 → GritManD. S final decision. Principle: Measurement is life. Description, not proof. — PHILIA OS | 0∞1∞0. 5∞
