// Friends get the history (Robins besluit, 30-7). A friends-only post used to
// be a moment-snapshot: delivered to the followers of that instant, hidden
// from the outbox, so a friend added LATER could never see it in a feed. Now
// the outbox answers by audience, and the backfill a fresh follow triggers
// identifies itself, so the past comes along with the friendship.
//
// And the door stays a door: a verified caller this instance BLOCKS gets an
// EMPTY collection, not even the public set.
