Rationality conjecture for affine osp(1|2) super VOAs

Let kk be a positive integer. The affine algebra Lk(sl2)L_k({\mathfrak{sl}}_2) is expected to be a sub-VOA of Lk(osp(12))L_k({\mathfrak{osp}}(1|2)). Affine osp(1|2) rationality conjecture. The coset satisfies

Com(Lk(sl2),Lk(osp(12)))Vir(k+2,2k+3),\operatorname{Com}\left(L_k({\mathfrak{sl}}_2),L_k({\mathfrak{osp}}(1|2))\right)\cong\operatorname{Vir}(k+2,2k+3),

and, in particular, Lk(osp(12))L_k({\mathfrak{osp}}(1|2)) is a rational super VOA. This proposes an explicit Virasoro coset description together with rationality for every positive integer level; the supplied text gives no resolution status.
