   5# Higgs Field from Recognition Vacuum — A1 SM Lagrangian Depth
   6
   7The Higgs vacuum expectation value v = 246 GeV arises from the
   8J-cost minimum of the EW recognition vacuum.

  10RS: V(φ_H) = J(φ_H/v) = ½(φ_H/v + v/φ_H) - 1.
  11Minimum at φ_H = v (J = 0).
  12Spontaneous symmetry breaking: v ≠ 0 chosen by boundary conditions.
