The ramp comparison is not a fifth closure

The supplied ramp identity is

It supplies a compensating coordinate response in the classical covariance calculation. It is not an invariant numerical value by itself XAST,XEnter.

The excluded-edge comparison has, in its source discrepancy convention,

This is a different functional with a different parameter and prescription from (eq:gap). An accidental equality of numerical values would not identify the two constructions.
