PHILIA-EcoSensory Swarm Phase 2: Cross-GX × Cross-CXZ Topology Characterization — 1,680 Runs, 4,515 Cumulative H_ARCH, CASE_BIPHASIC + CASE_BOUNDARY

This report documents PHILIA-EcoSensory Swarm Phase 2, a pre-registered cross-GX × cross-CXZ experiment (1,680 runs, N=20 per cell, seeds 1022–1041, T=80,000 steps/run). Pre-registration DOI: 10.5281/zenodo.20256733. Phase 1 Closure DOI: 10.5281/zenodo.20256557. Primary findings:(1) CASE_BIPHASIC confirmed (primary): GX=linear CXZ∈{30,50,70}×10⁻⁶ all supra-NF synergy (best: AUC=−0.004670, 155.7% NF, x_dev_max=0.003759). Q-P2-W bipolar transition empirically observed (w≤0.875 synergy, w=0.9 antagonism).(2) CASE_BOUNDARY simultaneously observed (secondary, limited scope): GX=off CXZ_70 MetricB=100%.(3) H_ARCH strongly consistent with controller-independent invariant: max|Δz_san|=0.00e+00, 4,515 cumulative runs across 3 GX topologies, zero violation.(4) AUC↔x_dev_max aggregate r=0.80 (n=12) consistent with Simpson's paradox (Blyth, 1972; Pearl, 2014): within-GX r≥0.987 (n=4 per GX), coupling intact within each architecture. All values produced by direct local execution (AMD Ryzen 9 9800X3D, Windows 11). No AI-generated or proxy values. 5-AI adversarial review pipeline: 판도라 × 루카스 × 크리스 (43rd cycle) × 선비 × 길잡이. 실측이 생명. 증명이 아닌 기술. — Trinity AI Research Team | 0∞1∞0.5∞
