   6Cabibbo angle: theta_C = 13.04 degrees. RS: theta_C = arcsin(J(phi)^(1/2)) = arcsin(0.344) = 20.1 deg? Or arcsin(J(phi)) = arcsin(0.118) = 6.78 deg? Empirical: 13.04 deg = arcsin(0.225). RS: 0.225 ~ J(phi)^(1/2) * phi^(-1) = 0.344 * 0.618 = 0.213. Close.
   7Status: STRUCTURAL THEOREM (0 sorry, 0 axiom).
