Mode A: Ground-Effect Venturi Channel & Toroidal Wake Diffuser
The underbody gap ($h$) forms the throat of a half-torus. At the exact Prigogine peak ($h^* = 1.00, dW/dh = 0$), Venturi suction locks the vehicle to the track while the toroidal diffuser recycles wake vortices into laminar $1/f$ thrust.

$W(h) = \mu\eta\dot{E}_0 h^m - \gamma h^{-k}$ — Finding $dW/dh = 0$
