snapshot

The current merged CRDT state (all entries, including departed/stale).

Intended for inspection and persistence. Not a frame to broadcast: it carries other replicas' slots, so feeding it to a remote received relays entries this replica did not author — see the update contract in the class KDoc. Publish only your own slot. If a peer must exchange whole states anyway (generic anti-entropy), the receiving side merges it with relayed, never received.
