Commentary.
Complementary contact support places the residual measure on the real zeros of the canonical entire contact function. Positive pressure and Schwartz decay confine those zeros to a compact interval.
Analytic isolation makes the real contact set finite. Evenness then splits every singleton mass equally between its positive and negative Dirac representatives, including the possible zero atom.
