PHILIA-EcoSensory Swarm v50: The Linear Geometry of PHINATURAL — z = 0. 42 − 0. 22·w Across Three Architectures

We present PHILIA-EcoSensory Swarm v50, a comprehensive longitudinal self-audit of 400 runs across eight controlled experiments (Tier A, Rec1–Rec7), establishing the causal mechanism underlying PHINATURAL z-axis drift observed across PHILIA versions v32–v49. Through a complete w-clamp ladder (Rec7: L0/L1/L2 at w=0/0. 5/1. 0), we confirm the linear z-attractor equation: z (w) = 0. 4234 − 0. 2159·w (R² = 0. 991) This relationship holds across three independently developed architectures (v32 single Phicenter, v34 output-blend, v49 3-Gearbox input-blend). Cross-architecture invariance is most striking at w=1. 0 (Taxi only): v34 z=0. 2019 vs v50 z=0. 2016 (Δ=0. 0003), despite different hardware (Intel N100 vs Ryzen 9800X3D) and seed sets (N=5 vs N=20). Key findings: (1) PHINATURAL = 0. 34, 0. 19, 0. 42 is the w=0 limit of a continuous attractor family, not an architecture-specific eigenstate. (2) >85% of z drift is caused by direct Taxi (NYC Taxi) input entropy injection (Iₑff → Sₕistory → Hᵢ → z = 1 − Hᵢ/Hₘax). zKL and Neuron type contribute negligibly (<1%, 0%). (3) Two causality regimes identified: v34 temporal corr (w, z) and v50 stationary mean (z|wclamped) are complementary — Being (geometric law) vs Becoming (dynamic response). (4) v49 Neuron class modular cleanness empirically verified: PhiliaV35Neuron with zKL/PPG OFF reduces algebraically to PhiliaV32NeuronSimple.
