Detailed Description

The tank columns a burn records, and the liquid surface among them.

A saturation margin at the tank is the tank pressure against the vapour pressure
of the liquid the ullage touches. With stratification on that is the surface
layer, not the bulk, and the trace has to carry it (EngineDesign/docs/layerx/
AUDIT.md 5.4). Off, the surface *is* the bulk, and the column says so exactly.
