What
If creating the messaging sockets directory fails, Claude now maps its user id back to the host user id and retries in a per-user fallback directory instead of giving up, marking the session as running degraded.
Details
The recorded cause is primary_dir_refused_fell_back.
Both the in-namespace and host user ids are now recorded so peer ownership can be checked against either.
Evidence
primary_dir_refused_fell_back
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
