Motivic Gersten's conjecture

Let RR be a commutative regular local ring, let MRp\mathcal{M}_R^p denote the exact category of finitely generated RR-modules supported in codimension at least pp, and let M#M_{\#}, for #{add,loc}\#\in\{\operatorname{add},\operatorname{loc}\}, be the corresponding additive or localizing motive in Ho(M ⁣ ⁣otdg#)\operatorname{Ho}({\mathcal{M}\!\!ot}^{\#}_{\operatorname{dg}}). For integers 1pdimR1\leq p\leq\dim R, consider the inclusion functor MRp1MRp\mathcal{M}_R^{p-1}\hookrightarrow\mathcal{M}_R^p.

Motivic Gersten's conjecture. For any commutative regular local ring RR and any integers 1pdimR1\leq p\leq\dim R, the inclusion functor MRp1MRp\mathcal{M}_R^{p-1}\hookrightarrow\mathcal{M}_R^p induces the zero morphism

M#(MRp1)M#(MRp)M_{\#}(\mathcal{M}_R^{p-1})\to M_{\#}(\mathcal{M}_R^p)

in Ho(M ⁣ ⁣otdg#)\operatorname{Ho}({\mathcal{M}\!\!ot}^{\#}_{\operatorname{dg}}), where #{add,loc}\#\in\{\operatorname{add},\operatorname{loc}\}.

This is a motivic strengthening or analogue of the KK-theoretic Gersten conjecture. The paper presents it as a question in the motivic setting, and the supplied text gives no resolution status.
