We generalize the twisted cohomology ring constructed in Balmer, Gallauer, The geometry of permutation modules that uses the classification of endotrivial complexes. This gives a construction for which the “comparison map” is an embedding for any finite $p$-group. Some of these techniques may generalize to abstract settings under certain compatibility conditions.
