LeanPool.NavierStokesAndEuler.Euler.ParentPacketHistoryNeighbor

Spatial variation of the actual activation history retains the parent's label scale. The constants are computed from the prescribed coefficients and the older frame, not from an estimate on the new primary.

The coefficient of the label scale in the actual history difference bound. All zeroth norms belong to the restricted source coefficients.
