What it says
A paged list (the feed, notifications: any item type with keys distinct in the server's list) is a contiguous run of the server's list, in its order: no item twice, none skipped. A list that is a run stays one when the next page is appended, when a head page puts new items on top or replaces it, and when new items arrive at the server's head.
