custodian_unqualified

  ✗ A subject's custodian ladder leaves the brand of record for a role whose credential the brand doesn't hold. Put a role that holds the credential ahead of 'brand' in custodian, or declare the brand's credential in brand.ts. translation's certified translation names the brand as custodian of record for the translator, and the brand holds no sworn translator: put a role that does first.
