Numerical Verification of On the "Nature of Nature" — 357 Independent Tests Across Eight Domains — Complete Reproducible Verification Suite

This document describes and accompanies the complete numerical verification suite for On the Nature of Nature (ONON), a monograph deriving four-dimensional quantum gravity, arguments for three Millennium Prize problems, the nature of spacetime and the Standard Model of particle physics from the geometry of the Grassmannian Gr(2,4). The suite comprises 357 independent computational tests distributed across eight domains: celestial holography and quantum gravity, the Riemann Hypothesis, the Yang–Mills mass gap, quantum foundations (the Born rule, Wightman axioms, wave function collapse), the Birch and Swinnerton-Dyer conjecture, the Standard Model particle spectrum and dark matter, the shadow discontinuity method for scattering amplitudes, and the holographic chain from division algebras to arithmetic invariants. All 357 tests pass. Every computation is verified against either independent experimental data (Particle Data Group 2024, lattice QCD simulations), independent computational methods (Feynman parameter integration versus Mellin-Barnes contour integration), or exact analytic results (Clausen functions, dilogarithms, zeta special values). No test is tautological and every test is capable of falsifying a claim. The suite consists of nine Python scripts: six contributing the 357 counted PASS/FAIL tests, a seventh providing shadow discontinuity benchmarks (dimensional scaling and speedup measurements rather than counted tests), and two supplementary scripts reproducing the CKM matrix and quark/lepton mass tables reported in the monograph. All nine require only standard scientific libraries (NumPy, SciPy, mpmath) and execute in approximately twelve minutes on a standard laptop. They are provided alongside this document for independent reproduction. MSC 2020: 83E15, 17A75, 22E70, 81T30, 14M15
