brand_credential_missing

  ✗ A rules row names a credential the brand holds, and the Brand doesn't declare it. Declare it in brand.ts, under Brand({ credentials }), with the verifier that keeps it fresh. The sign row names the brand credential registry account, and brand.ts declares no credential by that name.
