   7Five canonical atmospheric layers (troposphere, stratosphere, mesosphere,
   8thermosphere, exosphere) = configDim D = 5.

  10In RS: atmospheric stability = J-cost balance.
  11Convective instability: J > 0 (parcel rising).
  12Inversion layer: J < 0 would violate J ≥ 0, so instead: stable = J = 0.
  13
  14Five canonical weather phenomena (high pressure, low pressure, fronts,
  15jet streams, ENSO) = configDim D.
  16
  17Lean: 5 layers, 5 phenomena.

  19Lean status: 0 sorry, 0 axiom.
