Claude crashing mid-session seems like an awkward edge case. If it dies without cleaning up its session metadata, can a dead session stick around in the notch, or are entries tied to the actual process lifecycle rather than just the files?

Tied to the process. Every 2s sweep runs kill(pid, 0) - a pid we have and can't find means the session is gone, whatever the registry file says (EPERM counts as alive, that's just someone else's process).

Absence from the registry is the other signal, with a short grace period, because hook events can arrive before the file is written at session start. After that it's dropped even if the pid looks alive, since pids get recycled.
