FTH0061canonicalv1explosion_barrier (theorem)
/-- [I.T13] The explosion barrier: B does not imply everything. Specifically, impl B F = N, not T. This is the central paraconsistent feature of Truth4. Calculation: impl B F = join (neg B) F = join N F = N. Since N <> T, the implication B -> F is not "true". -/
