The CASCADE Yang-Mills Suite (P21–P25): Pisot Arithmetic, Automorphic Lifting, Arithmetic Bowen-Series Coding, Coholonomy Geometry, and Geometric Langlands — A Complete First-Principles Proof of the Yang-Mills Mass Gap

This record contains five interdependent papers (P21–P25) of the CASCADE Framework, uploaded as a single suite because together they constitute a complete first-principles proof that SU (2) Yang-Mills theory on ℝ⁴ admits a positive mass gap Δ = δ₄ × mₚ = 360 MeV, where δ₄ = log (ψ₄/|ω₄|) is the spectral gap of the companion matrix of the single integer polynomial P₄ (x) = x⁴ − x³ − 1. All physical predictions within this suite use the proton mass as the sole QCD scale normalization. Within the complete CASCADE framework (companion v10 suite), is itself derived from first principles via Newton’s constant (0. 002%), the Planck scale, and the Higgs VEV, making the total free parameter count zero. The proof flows entirely from the discriminant −283 of P₄, the Baker-Stark theorem, and the Galois group S₄ = Gal (L/Q) where L is the splitting field of P₄. The five papers form a strict logical chain. P21 proves that the two-dimensional Artin representation ρ₂ of S₄ is automorphic — realized by a newform f₁ ∈ S₁ (Γ₀ (283), χ₋₂₈₃) — and establishes the Farey wheel eigenvalue identity λ₁ (Γ₀ (283) ) = 1 + 2√71 and the universal Pisot correction amplitude. P22 closes the RS3 gap by proving the Arithmetic Bowen-Series Theorem: the std₃-twisted Ruelle zeta of the geodesic flow on Γ₀ (283) \ℍ equals 1/ (1 − u − u⁴), via the inner word hierarchy and the single 284-cycle structure of the Farey map on ℙ¹ (ℤ/283ℤ). P23 introduces coholonomy as the H¹ obstruction language of the CASCADE Framework, proves dim_ℝ (ℳPin (SU (3), Σ̃/σ) ) = 13 = ℓ₃ by two independent methods, and gives the GIT compactification with boundary strata of dimensions 13, 12, 10, 0. P24 assembles the complete Yang-Mills proof: five algebraic steps, three Wightman lemmas, the OS reconstruction theorem, and the coholonomy transfer establishing the area law without circularity. P25 closes the final argumentative gap by deriving char (TYM) = x⁴ − x³ − 1 from the Hitchin integrable system on X₀ (283) via the Atiyah-Bott adiabatic reduction, the Goldman symplectic correspondence, and Geometric Langlands — replacing the mode-counting argument of P24 with a theorem, and completing the Langlands dictionary for P₄ across all four faces: classical, arithmetic, geometric, and physical. The suite makes four parameter-free falsifiable predictions testable by lattice Monte Carlo at βWilson = 5. 120 on a 32⁴ lattice: σₗat · a² = log ψ₄ = 0. 32228, σₗat/mgap = 0. 8400, Tc/√σ = 0. 6903, and convergence rate a⁰. 38370. The deconfinement temperature Tc = 294. 91 MeV matches lattice data to 0. 03%. The proof establishes both parts of the Clay Millennium Yang-Mills problem: existence (Wightman axioms satisfied via OS reconstruction, P24) and mass gap (Δ > 0, algebraic, P21–P25).
