Critical-point behavior under physical exponent specialization
Determine whether the generic critical-point degree of the affine divisor arrangement associated with the zonotopal stringy integral is preserved under the constrained physical exponent specialization, and whether a corresponding critical-point pushforward to the zonotopal correlator exists.

Whether this generic degree is retained under the constrained physical exponent specialization, and whether a corresponding critical-point pushforward exists, are left open.
