The level-restricted X=M fermionic formula conjecture

Let $B_0$, $B^{r_1,s_1},\ldots,B^{r_L,s_L}$, $X_l$, $M_l$, and the energy normalization $c$ satisfy the assumptions of the inhomogeneous X=M conjecture. Let $l$ be a positive integer.

Level-restricted X=M conjecture. One has

$$X_l(B^{r_1,s_1}\otimes\cdots\otimes B^{r_L,s_L},0,q) =q^cM_l(W^{(r_1)}_{s_1}\otimes\cdots\otimes W^{(r_L)}_{s_L},q),$$

where $M_l$ is the level-restricted fermionic form defined in the source. This is the level-restricted analogue of the inhomogeneous X=M formula; the source gives no resolution status.
