The compactification conjecture for constructible sheaf data on Alexandrov spaces

From papers

Fix a finite field F\mathbb{F} and let LF(n,D,κ)\mathcal{L}_{\mathbb{F}}(n,D,\kappa) consist of pairs (X,[F])(X,[\mathcal{F}]), where XX is an Alexandrov space of Hausdorff dimension at most nn, diameter at most DD, curvature at least κ\kappa, and F\mathcal{F} is a constructible object of Db(ShF(X))D^b(\operatorname{Sh}_{\mathbb{F}}(X)). The sheaf-moduli topology conjecture. There should exist a Hausdorff topology on this set satisfying the stated sequential compatibility with Gromov–Hausdorff convergence and stabilization of pushforward objects, continuity of the map to constructible-function data and to Alexandrov spaces, closedness under enlargement of (n,D,κ)(n,D,\kappa), compactness of the closure of smooth manifolds with rank-one constant sheaf, and finiteness of the fibers of the map from that closure to the Alexandrov-space moduli. The source gives no proof of these properties; they are proposed as a framework for compactifying sheaf-theoretic data.
