From the perspective of math: A single integer, D = 3, forces the existence of a torus knot T²(13,3). From this geometry alone — with zero free parameters — the following are derived: the weak mixing angle (sin²θ_W), the strong coupling constant (α_s), the fine structure constant (α⁻¹ = 137), the dark energy fraction (Ω_Λ), the number of particle generations (N_gen = 3), the Cabibbo angle, the CKM matrix element |V_ud|, the Higgs mass (m_H), and the electroweak coupling (α₂⁻¹). All predictions match measured values to an average deviation of 0.3σ. The framework introduces a cartographic perspective factor L = R/(R + r·cos(6π/R)) = 0.97294..., the computable residue of a finite observer embedded in an infinite geometry. Physical constants are refracted values: Q_observed = Q_geometric × L^w. The Hubble tension, the strong CP problem, the arrow of time, Born's rule, and the second law of thermodynamics each receive geometric explanations from the same structure. D = 3 is shown to be the unique integer satisfying knot theory, projective geometry, Whitney embedding, and cyclotomic chain closure simultaneously. The joint probability of five independently measured constants converging on the same (R, r) pair by chance is approximately 5 × 10⁻⁹.
