Microlocal endomorphism conjecture for singular support

Let XX be a smooth rigid analytic variety, and let FDzc(b)(X)\mathrm{F}\in D^{(b)}_{zc}(X). Here SS(F)SS(\mathcal{F}) denotes the singular support and suppμhom(F,F)\operatorname{supp}\,\mu hom(\mathcal{F},\mathcal{F}) the support of its microlocal endomorphism object.

Microlocal endomorphism conjecture.

SS(F)=suppμhom(F,F).SS(\mathcal{F})=\operatorname{supp}\,\mu hom(\mathcal{F},\mathcal{F}).

This identity would in particular give positive answers to the questions concerning smooth pullback and analyticity of singular support. The source does not state a general resolution status.
