WHY IT NEEDS A POLICY

Why memory_undelete needs a policy

This tool reverses a soft delete, restoring previously deleted data. Since the deletion was 'soft' (reversible), the undelete is a write/create operation that recreates/restores the record. It is not destructive, financial, or execute in nature. Severity is low as it only affects the memory store of this semantic memory system.
