In a survey article here http://arxiv.org/abs/2112.12010v1Algebraic geometry in mixed characteristic, B. Bhatt writes
For instance, given a commutative ring $R$ with a finitely generated ideal $I$,
- the assignment carrying $R$ to the $\infty$-category $D_{I−comp}(R)$$D_\text{$I$−comp}(R)$ of derived $I$-complete $R$-complexes forms a stack for the flat topology (or even a suitably defined $I$-completely flat topology), unlike the corresponding assignment at the triangulated category level.
What would be a reference for the above sort of statement? By this I mean I don't need a reference for that exact fact, although that would be fine too. I know what the words individually mean, but I have never seen a place where I can get an idea for how to go about proving this.
This question is very similar to the following question, which at the time of writing has no answer:
