Obfuscation Packets I1–I5 (Signature Chain) и CPS (Custom Protocol Signature)
Before initiating a "special" handshake (every 120 seconds), the client may send up to five different UDP packets fully described by the user in the CPS format. The primary packet—I1—contains a hex snapshot of an actual protocol (e.g., a QUIC Initial handshake), which can also be randomized. The remaining packets, I2–I5, increase entropy through counters, timestamps, and random data.
