The actual fixed-base residual in every common chart #
Pressure and error are normalized values of the same final Cartesian base. The equation is derived from its proved residual identity on the entire free auxiliary lift, rather than only on a physical graph.
The derivative calculation permits a non-unit source viscosity and a non-injective coordinate map. This is used to keep every auxiliary value free.
The full residual depends only on germs, including its second derivatives.
Translation invariance propagates through every derivative in the residual.

Cylindrical components of the actual summed velocity equal its values on the zero-angle ray. This uses its defining curl, including every slow order.
