Let’s say we have lemmy instances A, B, C.

alice from A makes a post “Hello, world” to B. What happens? How is it processed on servers A, B, C and how do users from A, B, C receive her post?

      I assume that if someone from a new instance (D) subscribes to foo, then D will need to request all the old posts from foo, since they weren’t pushed to D?

      Lemmy is pretty bad about backfilling content. Communities do have outboxs, but these only list the last 50 posts and you can’t get the vote or comments on any of them. See GitHub issues #5283, #3448 and #2004.

      ActivityPub works like a magazine subscription. They don’t send you back issues for subscribing.
