250The homogeneous Friedmann–Robertson–Walker background sits at the J-cost
251minimum `J(1) = 0` with zero ledger gradient flow. The recognition operator
252is at equilibrium on a homogeneous state, so there is no lag and no
253enhancement. The background Poisson equation is unmodified standard GR. -/
