Test 3 expects invalidForeignKey, as MT-3 says. A tenant admin reads its own tenant through sysTenantGet and sysTenantQuery, added to the default Tenant Administrator role for new installs only. The server adds nothing for MT-7's dashboard list. The MT-19a submission warning is deferred. MT-22's logo is the urn:inbuxa:jmap account capability's logo field (contract C-1).
