WIP snapshot before pivot to sing-box+TUN. Reached: - TCP redirect via streamdump pattern (swap+Outbound=0+reinject) - SOCKET layer for SYN-stage flow detection (avoids FLOW Establish-too-late race) - Lazy PID→name resolution (catches Update.exe inside procscan tick) - UDP forward via SOCKS5 UDP ASSOCIATE relay + manual reinject - Result: chat works, voice times out (Discord IP discovery / RTC handshake fails) Reason for pivot: WinDivert NAT-reinject pattern has subtle layer-3 semantics issues that DLL-injection / TUN-based proxies sidestep entirely. Going with embedded sing-box + wintun as the engine — proven path for Discord voice through SOCKS5. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
