For mode=selected, 'timeline' is the moment the item became selected (publications.selected_ready_at), newest first; each article appears once. 'published' uses the third-party publication time only, for either mode, which drops slow pushes out of short windows. Both timestamps are always returned on every item as publishedAt and discoveredAt. Item fields are unchanged."
