Functoriality of the motivic pro-semisimple completion

Let (X,X~)(X,\tilde X) and (X,X~)(X',\tilde X') be pairs as in the paper, with a morphism (X,X~)(X,X~)(X',\tilde X')\to(X,\tilde X), and let f^(λ)mot:Π^motΠ^mot\hat f_{(\lambda)}^{\operatorname{mot}}:\widehat{\Pi'}^{\operatorname{mot}}\to\hat\Pi^{\operatorname{mot}} be the homomorphism induced by this morphism for a non-Archimedean place λ\lambda not dividing pp, well-defined up to (Π^mot)(\hat\Pi^{\operatorname{mot}})^\circ-conjugation. Functoriality conjecture. The (Π^mot)(\hat\Pi^{\operatorname{mot}})^\circ-conjugacy class of f^(λ)mot\hat f_{(\lambda)}^{\operatorname{mot}} does not depend on λ\lambda. This asserts the expected compatibility of the motivic pro-semisimple completion with morphisms of smooth varieties; the supplied text gives no resolution status.
