The fine-structure constant α has been measured to twelve decimal places but never derived from first principles — until now. The Utterance Model (UM) derives α from two logical axioms (A = A and X = 0) with zero free parameters: α_struct = 1/(64π) + 1/(16π²e) = 0.0073032..., giving 1/α_struct = 136.926 ≈ 137. The Boundary-Conditioned Reality (BCR) framework independently models physical reality as a universal scalar field constrained by boundary conditions B. Its governing equation predicts that α is not a fixed constant but a boundary-dependent effective value: α_eff = α_struct − γ · P(B) · [1 − P(B)], where P(B) = 1/(1 + e^(−γB)). The two frameworks were developed independently and without coordination. Their convergence on the same numerical thresholds (0.618 and 0.854), the same two-term structure for α, and the same identification of γ_EM = α_struct constitutes independent structural confirmation. In the electromagnetic regime, BCR's sole free parameter collapses to the UM-derived constant: no free parameters remain. The UM validation record spans seven particle-physics and cosmological predictions — including lepton masses, the Higgs VEV and mass, and the dark energy equation of state — all within the model's derived 3% epistemological bound. Multiple independent CMB analyses report non-zero cosmic birefringence (β ≈ 0.2°–0.4°, ≥ 2.4σ), consistent with boundary-induced polarization rotation predicted by the framework. The predicted boundary-dependent variation Δα/α ~ 10⁻⁸ under controlled laboratory conditions is accessible with current optical lattice clock technology at the 10⁻¹⁸ precision level. The experiment is fully specified, with pass/fail criteria, a three-step calibration protocol for the boundary parameter, and identified target laboratories (NIST, JILA, PTB, NPL). The derivation of α_struct is the subject of USPTO Patent Application No. 19/640,364 (Inventor: Charles Anthony Hyatt Battiste, Quality Compliance Consulting Inc.).
