 servers during `session.open`. There is no separate reload operation.
 
+Conversation and combined rewind require a core-restored session with persistence. After a
+successful rewind, Paseo closes the session and reopens its latest persistence value with
+`history: "replay"`. Publish the retained native branch before `session.ready`, including its
+children. File-only rewind keeps the current session and conversation history.

 uses `restoration: "parent"`; emit it as another `session.opened` event with `parentSessionId` and
 recreate it while restoring the parent.
