The atproto firehose, restaged as a freight yard. Every commit is a shipment filed into a lane by its collection — posts, likes, reposts, follows, blocks — and animated rolling from a DEPOT (the account's own PDS, where the record was written) to the HUB (the relay, where every subscriber downstream picks it up). A deleted record has no body left to inspect, so a delete comes back through as a recall heading the other way — with its real size if we saw it get created recently, "size unknown" otherwise, same honest gap as chimehose. Nothing is recorded or sent anywhere; it all runs live in your browser off the public Jetstream.
