Symmetric monoidality of duality for almost perfect modules over the sphere spectrum

From papers

Let AA be a coherent connective commutative algebra over the sphere spectrum S\mathbb{S}, and let \APerfA\APerf_A denote the category of almost perfect AA-modules. Consider the AA-linear duality functor

()\IntHomA(,A) ⁣:\APerfA\op\ModA.(-)^\vee \coloneqq \IntHom_A(-,A)\colon \APerf_A^{\op}\longrightarrow \Mod_A.

Sphere-spectrum duality claim. The result established for coherent, eventually coconnective commutative dg algebras over \C\C also holds over S\mathbb{S}: the restricted duality functor ()(-)^\vee is symmetric monoidal.

This is a proposed extension of the preceding proposition from the complex numbers to the sphere spectrum. The supplied text gives no further evidence about whether the claim has been proved.
