> - CasForwardResponse holds a single-use RowIterator that serialize and serializedSize both drain, so the write emits an empty partition and tripped messaging's length assertion. deserialize had the mirror defect.
> - Forwarded timeouts arrived nested in an ExecutionException and became bare RuntimeExceptions
> - A CAS that applied reports no result, which read as "no forwarding needed", so the caller re-runs it locally
