Well, having had a closer look it appears that’s how the thing is cast. There’s no hairline joint / where a shim could be overlapped to spring in and the bb threads run right in, so appears to be a continuous surface. Could that be possible?
Is it a ‘holeless’ tube for structural reasons, given the lugless construction?
