  59/-- **C-001 Resolution**: The fine structure constant is determined by φ.

  61    α_lock = (1 − 1/φ)/2 has no free parameters.
  62    It is the unique coupling compatible with the ledger's
  63    reciprocal symmetry and self-similar closure.

  65    Relationship to measured α ≈ 1/137 requires the conversion
  66    from RS-native to SI units (λ_rec calibration). -/
