Continuity conjecture for synthetic curvature measures

Let XiAlexn(1)X_i\in\text{Alex}^n(-1) be a sequence of Alexandrov spaces converging to XX in the Gromov–Hausdorff sense without collapsing. Let μXi\mu_{X_i} and μX\mu_X denote their synthetic curvature measures. Continuity conjecture. Then

μXiμX.\mu_{X_i}\to\mu_X.

This proposes continuity of the synthetic curvature measure under non-collapsing Gromov–Hausdorff convergence. The source presents it as an open question and gives no resolution.
