I believe that Automerge internally stores all operations in an eventually consistent total order, which you can use as a substitute for the server in server reconciliation (cf. https://mattweidner.com/2025/05/21/text-without-crdts.html#d...). However, Automerge does not actually do that - instead it processes text operations using a traditional CRDT, RGA, probably because (as you point out) undoing and replaying ops is not trivial to implement.
