Research direction
Start in internal/services/wireguard/wireguard_impl.go around lines 135-139 and inspect the surrounding peer-selection logic. Confirm whether selectedPeer remains valid after the range loop and check the repository's Go tests if available. Done means resolving or validating the reported range-variable reference without changing intended peer selection behavior.
