Collapsing-level conjecture for boundary VOAs of 3d mirror theories

Let a non-rank-zero 3d $\mathcal{N}=4$ SQFT be a three-dimensional supersymmetric quantum field theory with nonzero rank, and let its boundary VOA be obtained after a topological twist. A collapsing level is a level at which the corresponding vertex operator algebra has the stated collapsing behavior. Collapsing-level conjecture. For non-rank-zero 3d $\mathcal{N}=4$ SQFTs, their boundary VOAs after topological twists are at collapsing levels as a consequence of 3d mirror symmetry. The claim is presented as an expected consequence of 3d mirror symmetry; the supplied text does not state a proof or counterexample.
