WCF net.tcp (RemoteTcpIntegrated) against the live 2023 R2 historian is reset
at the socket-write/framing layer before any auth — both the event spike and a
basic Probe/ReadRaw throw the identical CommunicationException/SocketException
("forcibly closed by the remote host"). The 2023 R2 box does not serve the
legacy WCF transport; C2's "route via WCF" unblock is moot on this server class.
Sanitized: counts + native return codes + buffer lengths only.
