I hadn't had a good look at the lore book since getting the N4 rules, but reading through yesterday, it strikes me that Aleph has no dedicated section. Well, there's actually a couple of pages at the end of the book, but it almost seems as an afterthought. Anyone knows if there's any good reason for this? I mean, it could be due to lack of space (now that O12 is there), or a rush to get the books out. But maybe something more interesting, like some big upcoming changes?
ALEPH lore is in the Third Offensive book, still sold, and I think we can consider it "N4 compatible" (as Daedalus' Fall and Uprising). The new book may add more.
Aleph has scant mention in the "core rules" part of any edition so far up to and including N4. It was introduced in N2 Human Sphere - and then in the N3 Human Sphere book it was updated.
