The list of other Claude sessions can flag renames, unreachable cloud sessions and failed lookups.
Richer peer-session listing exists but only shows where the cross-session messaging gates are open.
What's wrong with this entry?
The list of other Claude sessions you can message can now say how long ago a session went by a different name, mark cloud sessions that the current cloud session cannot reach, and add a note when the cloud list could not be fetched at all. An empty list no longer prints a bare header. Whether this listing is reachable for a given user is decided by the gates on the cross-session messaging feature.
not reachable from this cloud session
