 238/-! ## Summary -/
 239
 240/-- RS derivation of electroweak breaking:
 241
 242    1. **Higgs potential = J-cost**: Same mathematical form
 243    2. **VEV = J-cost minimum**: Symmetry breaks spontaneously
 244    3. **W, Z masses**: From coupling to VEV
 245    4. **Photon massless**: U(1)_EM unbroken
 246    5. **Higgs boson**: Radial excitation of Higgs field
 247    6. **Hierarchy**: May be φ-related (under investigation) -/

 256/-! ## Falsification Criteria -/
 257
 258/-- The derivation would be falsified if:
 259    1. Higgs mechanism is wrong
 260    2. VEV doesn't minimize J-cost
 261    3. Additional Higgs bosons found (complicates story) -/
