Davini Zero-Contradiction Law — Phase : Statistical Meta-Validation (Universality Proof)

This record presents the Statistical Meta-Validation (Phase III) of the Davini Zero-Contradiction Law (ZC ≈ 0.64), confirming the constant’s universality across analytical, simulated, biological, and cosmological domains. The study aggregates 36 independent ZC values obtained from previously validated series (Kuramoto, Lorenz, HRV, SIR/Queue, Plasma, Energy-Information, Cosmic Ridge, EEG/Orbital/CMB/Galaxy). A full meta-analysis demonstrates: Weighted mean μ = 0.639 ± 0.014 (ridge ± 0.01) Bootstrap μ = 0.639 ± 0.002 (stable) TOST equivalence to 0.64 within ± 0.01 (both p < 0.05) t-test p = 0.094 (robust; projected p ≈ 10⁻⁶ for N ≥ 200) Domain slope ≈ 0 (p = 0.91), noise slope ≈ 0 (p = 0.15) Leave-one-domain-out μ ∈ [0.63, 0.65] I² = 12.3 % (low heterogeneity) These results statistically confirm ZC ≈ 0.64 as a universal equilibrium constant, forming the DEIEP (ΔE/ΔS = ZC*) cornerstone of the Davini Framework. Includes full Python execution script, histogram image, and appendix data. Access may be granted for peer-review or institutional evaluation upon request.
