Idle → Starting → Active → Failed lifecycle. bringUp resolves upstream IP, installs the driver (idempotent), runs initial procscan, opens redirector listener, builds filter + opens WinDivert handle, then spawns the diverter reader and 2-second procscan ticker. On every outbound TCP packet from a target PID: record (src_port → real_target) mapping, rewrite dst to 127.0.0.1:listener_port, re-inject. Loopback listener picks up the connection, looks up the original target, and SOCKS5-tunnels. P2.1 scope: no Reconnecting state, no panic recovery, no UDP forwarding. Those land in P2.2/P2.3.
