An Underwater Hearing on the Login Handshake: The All-Ciphertext Confirmation, the Truth of the Send Path, and the MITM Session on 128 Bytes

Five late-night hearings against the Moyu protocol: a hook on ws2_32!send proved every outbound C2S byte is ciphertext and every packet differs — a stateful stream cipher; the backtrace ironed out the three-layer division among framing, queue and send_wrapper, with encryption hiding inside the msgID-routed handler; the client behavior against the stub server reproduced three times identically (thirty frames in, seventy-one seconds of silence, one 128-byte ciphertext out, seventy seconds of waiting, disconnect); and the MITM proxy chain captured the first full sample of the official login handshake — an underwater hearing where every word was ciphertext and every word was transcribed.
