  nat_traversal_netdriver.cpp — path_of_titans

  Custom UE NetDriver for peer to peer listen server NAT traversal. libjuice (ICE/STUN/TURN) wired end to end across host registration, SDP signaling, and joiner connection state machines; server type agnostic so listen & dedicated servers share one ICE path. ICE transport stood up across all 10 shipping platforms — windows, mac, linux, android, ios, xbox series x|s, xbox one, ps5, ps4, and switch — with libjuice itself ported to the console targets (ps5, ps4, switch) and a custom Docker container authored for the deploy. PHP signaling/auth backend + Cloudflare Realtime TURN relay only the ~15% NAT fallback traffic — a projected ~$100K/yr relay bill turned usage based. UE Automation Spec regression gate; high impact crash fixes; AI assisted dev tooling.
