Remarks

A draft is its own record rather than a stage of OutgoingEmailRecord, because almost nothing an outgoing record exists for is true of one. It has no delivery, no recipient that has to be valid, no idempotency identity against a duplicate that could not be withdrawn, and no terminal stage — a draft is edited for as long as its owner keeps editing it. What it has instead is the one thing an outgoing record never does: a copy on somebody else's server that has to be replaced whenever the local one changes.

That replacement is the whole difficulty. IMAP has no command that changes a stored message, so a revision is an APPEND of the new version followed by a removal of the old one, and a process can die between them. The revision is therefore written down before the first command, and Stage is what a resumed attempt reads to finish the pair instead of starting it again.

It is derived personal data on the same terms as the mail beside it: a draft says who this mailbox's owner is writing to and what about. The addresses are here because a promotion cannot build an envelope without them, the message itself stays in the content store, and the record is erased with the mail it belongs to.
