Scheduled posts: the composer's clock button opens a "Post at" time (an hour ahead, on the quarter hour) and turns Post into Schedule. The note is signed now with that created_at, so a remote signer asks while you're there, and handed to the notifier, which publishes it at that time; nothing reaches a relay before then. What's waiting shows as "Scheduled (n)" under the composer and on your profile, each with Cancel (a kind 5 to the notifier, so it never goes out); one cancelled on another device leaves the list at the next status check
