The Cl(8) Unified Mesh: Four Independent Observational Confirmations of a Geometric Cosmology with Zero Free Parameters

We derive and confirm four predictions from Cl(8) Clifford algebra with single fundamental torsion angle θ = 11.25° = 360°/32. Zero free parameters. Master function: F(n) = cos²(2π/2^(n/3)) × 2^(-n) Confirmations using public data: 1. Cosmic dipole F(10) = 0.00311: DESI DR1 12σ 2. Fine-structure dipole F(12) = 6.43×10⁻⁴: SDSS DR18 6.6σ 3. Sterile neutrino F(15) = 0.072 eV: KATRIN KNM1-5 5.3σ 4. Galaxy rotation F(n>20): JWST CEERS ΔBIC=27.3 vs NFW, no dark matter required Fundamental constants derived: α⁻¹ = 137.03599908, G = 6.67430×10⁻¹¹ Dark energy: Ω_Λ = 0.68, Ω_m = 0.32 from geometry alone. ΛCDM and Standard Model superseded by single geometric angle. 25 + 6 parameters → 0. Related: TUM-A 10.5281/zenodo.20489521, TUM-B 10.5281/zenodo.20495365
