> In {{{}ReplicationSourceShipper#shipEdits{}}}, we currently return
> {{COMMITED}} when the WAL entry list is empty. This can incorrectly advance
> replication offsets, especially if previously submitted entries were not yet
> durably persisted (e.g., still in open WAL files on S3).
> We should return {{SUBMITTED}} in such cases and only return {{COMMITED}}
> when we know data is safely persisted, like on WAL close.
