macOS 1.5
- Determines the UDP network interface from the active TCP connection's local IPv6 address and applies the matching IPv6 scope.
- Recreates each connection's UDP socket with the TCP local IPv6 address and interface, preserving the negotiated UDP port on reconnect.
- Keeps left and right UDP routes independent and prevents incoming datagrams from replacing the negotiated destination.
- Logs full IPv6 interface zones, rate-limits repeated UDP send errors, and reports when sending recovers.
- Includes automated UDP send, receive, and reconnection tests. Resolution of the reported cross-screen freeze still requires real-device confirmation.
