@AaronMazel-Gee Thanks for reminding me of that! I've only read the first couple sections of the Raskin paper... I should probably revisit it at some point. In a similar vein, there's a pretty interesting appendix in Antieau-Mathew-Morrow-Nikolaus (
arxiv.org/abs/2003.12541) which talks about some of this graded/filtered cyclotomic stuff as well.
