Okounkov's monodromy formula for wall operators

Let $M(z)$ be a rational operator defining a quantum difference connection, and let $\mathsf{Mon}(z)$ denote its monodromy. For an integral cocharacter or wall parameter $\mathsf{w}$, define

$$\mathsf{Mon}_\mathsf{w}=\lim_{q\to 0}\mathsf{Mon}(a,zq^\mathsf{w}).$$

Okounkov's wall-operator conjecture. The wall operator is given by

$$\mathsf{B}_\mathsf{w}(z_\text{shifted})=\mathsf{Mon}_\mathsf{w}\cdot\mathsf{Mon}_{\mathsf{w}+\varepsilon}^{-1}.$$

This conjecture proposes that individual wall-crossing operators can be reconstructed from asymptotic limits of the monodromy of the quantum difference equation. The source gives no resolution status.
