We describe the closure of the Bridgeland stability manifold of X obtained using the masses of semi-rigid objects.This work is a part of a larger project with Asilata Bapat and Anthony Licata. I am deeply grateful to have them as collaborators. I thank Ziqi Liu, Emanuele Macri, Laura Pertusi, and Paolo Stellari for discussions related to this project.
