The trail of the open screens: the root the process's launch edge opened
(its screen and input), then, for every open screen, the edge it was
reached by (from an item, by the item's identity key) and the caller's
arguments, or the tab switch it was reached by — never the user's data. It is
bound to the viewer (dsUserId) and the device (uuid) it was written for;
a checkpoint, which carries the whole client snapshot, stores the path
without that binding. It closes nothing: an inner tab stays open, written
after the screen it replaced.
