LeanPool.NavierStokesAndEuler.Euler.PacketPressureScaleCosts

Literal good- and bad-interval upper-Hessian costs fit the existing summable scale family. The good contribution retains its factor delta.

The actual history contribution to the early-time size ratio is polynomial in the parent labels and reciprocal history length. The good interval keeps its absolute size constant.
