The singlet quantum-group correspondence

Let UqHs(2)\overline{U}_{q}^{H}s\ell(2) be the unrolled restricted quantum group, and let Rep ⁣wtUqHs(2)\mathrm{\bf Rep}_{\!\mathrm{wt}\,}\overline{U}_{q}^{H}s\ell(2) denote its finite-dimensional weight-module category. Let M(p)\mathcal{M}(p) be the singlet vertex operator algebra, and let RepsM(p)\mathrm{\bf Rep}_{\langle\mathrm{s}\rangle}\mathcal{M}(p) be the full subcategory generated by its simple modules under tensor products, finite sums, and subquotients. The singlet correspondence conjecture. There is an equivalence

Rep ⁣wtUqHs(2)RepsM(p)\mathrm{\bf Rep}_{\!\mathrm{wt}\,}\overline{U}_{q}^{H}s\ell(2)\cong \mathrm{\bf Rep}_{\langle\mathrm{s}\rangle}\mathcal{M}(p)

as C{\mathbb C}-linear ribbon categories. This is part of the proposed quantum-group description of the singlet VOA; the source does not state that it has been proved.
