Enum JournalAs 

pub enum JournalAs {
    Edit,
    Undo {
        of: Rev,
    },
    Redo {
        of: Rev,
    },
}

Which stack a record’s entry lands on, and what it does to the other — the whole undo/redo policy, stated once.

It is also a durable record’s kind, in the only spelling this headless crate knows: a replayed log hands each record’s kind over as one of these, so a reopened document rebuilds its trail by running this policy rather than a second copy of it.
