Fine-Structure Constant — Electromagnetic Fixed Point
Claim ID: EM.FP.01The fine-structure constant is the unique positive root of the cubic closure built from c₃ and the abelian coefficient 41 = 10 b₁. Existence and uniqueness are proved; the value lands 2.9×10⁻¹⁰ (1.9σ) from CODATA-2022. Typed [E]: the coefficients are exact identities, the Ward-origin reading of the equation is conditional [C] (ledger EM.FP.01).
