Indecomposable crepant categorical resolutions conjecture

Let $Y$ be a singular variety admitting crepant categorical resolutions, and call a categorical resolution indecomposable when it has no nontrivial decomposition in the relevant categorical sense. Indecomposable crepant resolution conjecture. Every indecomposable crepant categorical resolution of $Y$ is minimal. In particular, all crepant categorical resolutions of $Y$ are equivalent. The claim predicts uniqueness up to equivalence for crepant categorical resolutions, but the source provides no resolution of it.
