   5# Maxwell Equations from RS — A1 SM Depth
   6
   7Maxwell's 4 equations (Gauss E, Gauss B, Faraday, Ampere-Maxwell).
   8In RS: EM = U(1) gauge theory on recognition Hilbert space.
   9
  104 equations = 2^(D-1) = 2^2 = 4 (D=3 again).
  11
  12RS: EM field = J(E·B/(E_crit·B_crit)) at canonical threshold.
  13
  14Five canonical EM phenomena (static E, static B, induction, radiation, plasma)
  15= configDim D = 5.
  16
  17Lean: 4 = 2^2 = 2^(D-1) proved by decide.

  19Lean status: 0 sorry, 0 axiom.
