LeanPool.NavierStokesAndEuler.Euler.PacketForwardInitializedResidualEquation

The literal zero-history initialized packet supplies the all-order approximation residual identity, including its actual pressure gradient. Its velocity, time derivative and residual are the fields already constructed from the source profiles, not additional approximation hypotheses.

The actual direct-forward source packet has a lifted pressure gradient. Every component is constructed from its mean or oscillatory inverse.

Pressure gradient witness, constructed using GradientWitness.compact.
