N2  Ivo Herzog has pointed out to me that the main theorem of [1] cannot be correct, because as noted in his paper with Fu [2], for the Klein four group in characteristic two the image of a phantom map between two modules with no projective summands kills the socle of the first module, so the composite of two such maps is zero.
