We evaluate the inference rules and axioms of the logic system IF, implied as a superset of connexive logic. The inference rule gen is not tautologous, to refute the system at its outset. Four axioms are also not tautologous. What follows is that the seven properties claimed of separation, symmetry, internality, cut-eliminability, subformula property, admissibility of structural rules, and invertibility of rules are also not confirmed. Hence the IF logic system connexive logic in its entirety, and takes with it the conjecture of cut-elimination for intuitionistic fuzzy logic via nested sequents. These results form a non tautologous fragment of the universal logic VŁ4.
