PHILIA-EcoSensory Swarm v38–v38.2: From Input Bandwidth to Living Control — Trend-Deviation Perturbation and Criticality in a Dual-Channel Router

We present PHILIA-EcoSensory Swarm v38–v38.2, a unified experimental arc establishing the first empirical demonstration within the PHILIA framework of Living Control in a dual-channel Router system (19+ configurations, 5 seeds × 80,000 steps each). Building on v37's diagnosis of Input Bandwidth Limitation, the v38 series systematically resolved the scale mismatch problem and introduced structured trend-deviation perturbation. The central achievement: simultaneous satisfaction of F5' (Agility Index ≥ 0.008) and F8 (fft_low_ratio < 0.80), defining Living Control as the first empirically confirmed regime of bounded, responsive, eigenstate-preserving dynamics. Key progression:- v38: Scale mismatch identified — raw derivative injection insufficient- v38.1: Dual-channel structural breakthrough — F8/F9 first achieved- v38.2: Trend-deviation perturbation — Living Control achieved twice independently (S1-LT95: F5'=0.00801, S2-AD12: F5'=0.00804) Best configuration: λ_trend = 0.95, α = 0.05, a_d = 1.2.A critical gain window a_d* = 1.2 is identified, analogous to a phase transition at the boundary between order and disorder. Formal Lyapunov stability (Appendix B), continuous-time ODE analysis (Appendix C), and Fisher information analysis (Appendix D) confirm bounded-input bounded-output stability and maximum information transmission at the critical gain. All results executed on local hardware (AMD Ryzen 7 9800X3D, RTX 4080 SUPER 16GB). No AI-generated proxy values used. Trinity AI Research Team | 2026.04— PHILIA OS | 0∞1∞0.5∞
