Dual-Layer Light v5.0: The Open-Close Structure of Ma — A Complete Theory of φ₂ Perturbation

This paper completes the Dual-Layer Light framework (v1. 0–v4. 0) by introducing the Open-Close Structure of Ma — a unified description of the cosmic information density field φ₂ in its two observable states. CLOSED STATE (ground state): φ₂ = φ₀ (uniform) → c = constant (light speed invariance) → KOKU accumulates → market normal → thought stable. OPEN STATE (perturbed state): φ₂ = φ₀ + δφ₂ → c = c₀ + δc (|δc/c| 0. 5 (S > 0. 5 AND E_ν > 100 TeV = IceCube GOLD). Correlatable with Tendo Economics market return data. The unified formula V = N/D (SYSTEM YOSHIMITSU KATAYAMA) is identified as the economic-scale expression of φ₂ dynamics: when Ma opens (D→0), V→maximum. Six falsifiable predictions span astrophysical, precision measurement, biological, and economic scales. The Tendo Economics statistical record (GOLD +1. 547% vs BRONZE +0. 670%, p=0. 005) represents partial empirical support for Prediction 6.
