What scripthut has left on each backend's filesystem — source clones, agent workspaces, software stacks, and logs. Scans run on demand; cleanup deletes only entries scripthut itself created, never active or unrecognized ones. "Orphaned" means no run this server remembers references it (run records are pruned after 30 days).
No persistent filesystem to scan — {{ b.type }} instances are ephemeral.
