ReadonlyloggedThe logged-out declaration's screen was opened. A second logged-out launch on this process is refused, so the pre-session burst goes out once; once a session exists in the process the logged-in launch is the process's first and is allowed.
ReadonlystartedA logged-in launch ran: the process is started and the entry refuses another one.
The process facts the entry owns: whether it started the app, and whether it opened the logged-out root. Read-only outside this module; they have two writers —
OpenAppand the checkpoint restore (RestoreScreenLaunchState), which puts back the facts a checkpointed process held. They are not the stack's root — the launch edge is public and a bottom-bar tab brick may open one too — and not the navigation, which the pre-session login screens write as well.
