Sheaf quantization conjecture for the Givental–Hori–Vafa mirror

Let XΣX_\Sigma be the toric variety with Givental–Hori–Vafa mirror WΣW_\Sigma, and let Λ^\widehat{\Lambda}_{\geq} denote the Novikov ring. Write SQ(WΣ,Λ^)\mathrm{SQ}(W_\Sigma,\widehat{\Lambda}_{\geq}) for the subcategory spanned by sheaf quantizations of end-conic Lagrangians ending in Λ^\widehat{\Lambda}_{\geq}. Sheaf quantization conjecture. The category

SQ(WΣ,Λ^)\mathrm{SQ}(W_\Sigma,\widehat{\Lambda}_{\geq})

is equivalent to the derived Fukaya category of T(MR/M)T^*(M_{\mathbb R}/M) over the Novikov ring generated by Lagrangian submanifolds compactly Hamiltonian isotopic to Lefschetz thimbles of WΣW_\Sigma. This proposes a genuine sheaf-theoretic analogue of the Fukaya category over the Novikov ring, but the source gives no evidence that the equivalence is known.
