I was a bit confused at first, but I think I understand this now. Is the intention that these fields are only updated by breach-specific methods like record_breach? If so, that seems fine to me but it's a bit unusual. Can add documentation somewhere explaining how those fields work?

Yes, exactly. I mirrored that behaviour from Desktop, and it turned out to help in this case. I think we might want to harmonize this in the future; we could also think about putting these fields into the LoginMeta, or align on specific methods to update single fields or field set (eg like update_username_password, which would also make sense imo)

I have added documentation about this in the udl file.
