Liu's minimal mld conjecture for standard-coefficient Calabi-Yau pairs

Let $n$ be a positive integer, and let $(X,D)$ be the explicitly constructed klt Calabi-Yau pair in dimension $n$ with standard coefficients, namely the pair defined by the source's displayed construction. Its minimal log discrepancy is

$$\frac{1}{s_{n+1}-1}.$$

Liu's minimal mld conjecture. The number $1/(s_{n+1}-1)$ is the smallest possible minimal log discrepancy among all $n$-dimensional klt Calabi-Yau pairs with standard coefficients.

The claim proposes that Liu's example is extremal for minimal log discrepancies in this class. The source gives no resolution status.
