Facts

Facts are published once, whatever the number of interested consumers, and say only what happened. Deciding what to do about one, whether to send it to another homeserver, which homeservers, how to retry, belongs to the consumer.

Every fact implements Deduplicate, so a consumer that batches work can collapse a message the broker redelivers while it is still holding the first copy.
