The Standard Model's 25 free parameters — gauge couplings, fermion masses, mixing angles, and the cosmological constant — are experimentally measured inputs with no accepted theoretical origin. We present the Universal Generative Principle (UGP): a deterministic number-theoretic framework in which three axioms — locality, symmetry, and compression (minimum description length) — uniquely select a single integer seed, and a rigid arithmetic cascade from that seed generates the Category-A structural backbone of the Standard Model parameter spectrum — exact bare gauge-coupling rationals, canonical fermion triples, quantum-number assignments, and several parameter-free mass-ratio predictions. Calibrated, scale-anchored, and partially derived sectors are explicitly separated throughout by a five-status claim taxonomy (A_ Lean, A_ MDL, A/D, B, D;). The framework is complementary to QFT rather than a replacement: it fixes the numerical constants that a QFT Lagrangian takes as input, leaving QFT to supply the scattering dynamics. The Category-A derivation chain is machine-checked in Lean 4 with zero sorry and the standard Mathlib axiom signature; physics-bridge and A/D sectors are explicitly disclosed (companion formalization paper). How it works. The ridge level n=10 is pinned by three independent arithmetic certificates: ridge minimality (the smallest level admitting a prime-locked mirror-dual survivor pair, Lean: n10\ᵢs\ₘinimal\ₐdmissible\ᵣidge) ; global asymptotic sparsity (for all n, the joint "mirror-dual survivor with b₁=73" constraint forces n=10, Lean: asymptotic\ₛparsity\ᵤniversal) ; and a divisor-count certificate (the ratio (Rₙ) /D₁ = 15/8 unique to n=10 on 5, 20, Lean: ckm\ₜheta23\ᵣatio\ᵤniqueness). . . . Supplementary information (supplementaryᵢnformation. pdf) is bundled as a second file in this Zenodo record.
