Jordan's Langlands duality conjecture for generic skein modules

Let GG be a reductive group, GLG^{L} its Langlands dual, and MM a closed, connected, oriented 33-manifold. Let SkGgen(M)\operatorname{Sk}^{\operatorname{gen}}_{G}(M) denote the skein module with generic quantum parameters associated to MM. Jordan's Langlands duality conjecture. There is an isomorphism

SkGgen(M)SkGLgen(M).\operatorname{Sk}^{\operatorname{gen}}_{G}(M) \cong \operatorname{Sk}^{\operatorname{gen}}_{G^{L}}(M).

This is the skein-theoretic counterpart of Langlands duality for the cohomological Donaldson–Thomas invariants of local systems. The source presents it as Conjecture 1.1 of Jordan's work, and it remains open there.
