1-affineness conjecture for the local space of systems on the punctured disc

Let \CK\CK be the Laurent series field of the formal punctured disc, let \oD\oD denote the formal punctured disc, let GG be the reductive group with Lie algebra \cg\cg, and define the prestack of local systems by

\LocSys\cG(\oD)=\cgω\CK/G(\CK).\LocSys_\cG(\oD)=\cg\otimes\omega_\CK/G(\CK).

A prestack is 1-affine when the functors between sheaves of categories and module categories over its quasi-coherent category are mutually inverse equivalences.

Local 1-affineness conjecture. The prestack \LocSys\cG(\oD)\LocSys_\cG(\oD) is 1-affine.

This would identify sheaves of categories on the local space of systems with the corresponding module categories and is intended to support the local geometric Langlands framework; no resolution is given here.
