Remarks

The snapshot is an observation of server state and travels in one direction only: MailFathom reads mail read-only, so no application path turns any of these into an IMAP STORE. Above all, reading an email through MailFathom never sets \Seen remotely, and this type reports what the server said rather than what a local reader did.

ObservedAt is what separates "the server reported none of these flags" from "nobody has looked yet", which no combination of the booleans can express on its own. A caller that filters or displays a flag reads it together with the timestamp, because NeverObserved carries every flag as false without having asked any server.
