 113/-! ## PDG Experimental Mass Values (MeV/c²)
 114
 115These are the PDG 2024 central values. RS predicts masses in units
 116of E_coh (≈ 0.0901 eV), so comparison requires the calibration:
 117
 118  m_predicted [eV] = fermionMass(f) × E_coh_eV
 119
 120where E_coh_eV ≈ φ⁻⁵ eV ≈ 0.0901 eV.

 134## Mass Ratios (More Meaningful Than Absolute Masses)
 135
 136The φ-ladder predicts specific mass ratios between generations:
 137- m_μ/m_e ≈ φ¹¹ ≈ 199.0 (experimental: 206.8)
 138- m_τ/m_e ≈ φ¹⁷ ≈ 3571 (experimental: 3477)
 139- m_c/m_u ≈ φ¹¹ ≈ 199.0 × gap_correction (experimental: ~588)
 140- m_t/m_u ≈ φ¹⁷ ≈ 3571 × gap_correction (experimental: ~80000)
 141
 142The lepton ratios agree to ~4-5%. Quark ratios require gap corrections. -/
