"""Systematic port matrix: 3 gateway IPs x game ports (8001/8021/8041/8061/8081/12000).

Key insight from cached srvlist: 玖扬 servers have proxy= EMPTY, meaning the
client connects DIRECTLY to the game port — only some servers use the 12000
proxy. Earlier Test-NetConnection said 8001 closed, but asyncio connects
succeeded to 12000. Test-NetConnection may behave differently (ICMP/SYN
handling) — re-verify with real asyncio TCP connects.
