Module sync 

One record’s replication beside a peer: what to send it, and what it sent.

A host that replicates an open record itself — a page’s window over its peer, an attached view over its caller — keeps the record’s frontier and sends the record whole the first time, its changes after. Merging a peer’s change advances the frontier over exactly the changes it carried, so a route that publishes this replica’s own changes never sends it back, and what this replica made stays to go out.
