   6Noether's theorem: each symmetry → conservation law.
   7
   8RS conserved quantities:
   9- σ = 0 (recognition charge conservation)
  10- J total decreasing (second law)
  11- Momentum: from translation symmetry
  12- Angular momentum: from rotation symmetry
  13- Energy: from time translation symmetry
  14
  15Five canonical conservation laws (energy, momentum, angular momentum,
  16electric charge, baryon number) = configDim D = 5.
  17
  18Key: σ = 0 is the RS form of charge conservation.
  19
  20Lean: 5 conservation laws, 3 from spacetime = D symmetries.
  21
  22Lean status: 0 sorry, 0 axiom.
