   8# Gauge Coupling Hierarchy Scorecard
   9
  10The three SM gauge couplings (electromagnetic, weak, strong) form a
  11hierarchy determined by the RS forcing chain:
  12
  131. α⁻¹_EM ∈ (137.030, 137.039) from the φ-exponential formula
  142. sin²θ_W = (3-φ)/6 connects EM and weak sectors
  153. α_s = φ⁻³/π, gauge sum = 12π
  164. All three are RS-derived with 0 free parameters
