We derive the cosmological constant from defect network vacuum energy evolution, resolving the 10¹²⁰ fine-tuning problem. Key results: (1) Λ = ΛP exp(-2Γt) from quantum geometric flow with Γ=1.12 determined by network connectivity, (2) Double-logarithmic suppression from Zipf criticality: Λ ~ [ln(ln N)]²/(ℓP² t₀²) where N~10⁸⁰ is observable universe degrees of freedom, (3) Numerical prediction: Λtheory ≈ 2.8×10⁻¹²⁰ MP⁴ vs. Λobs = 2.9×10⁻¹²⁰ MP⁴ (agreement within 3%), (4) Critical temperature Tc ~ √ρΛ from structure formation threshold, linking dark energy to Zipf criticality, (5) Time-varying dark energy: w(z) = -1 + (1/3)d ln Λ/d ln(1+z), testable with DESI and Euclid. Framework explains: why Λ is nonzero (flow never fully stops), why Λ is tiny (exponential + logarithmic suppression), why Λ emerges at matter-radiation equality (criticality condition), and anthropic coincidence (observers exist only near s=1). Zero free parameters - all constants derived from network topology.
