Reproduced A/B on the dev box: with RP412STEAM=1 the wired pad
disappears from XInput because Steam Input intercepts Xbox controllers
for AppID 480. One-time client setting fixes it (disable Steam Input
for Spacewar, or globally for Xbox controllers); PadRIO hot-connects
within 3s once released. Our own AppID will configure this
server-side.
environ.ini in the dist now ships RP412STEAM=1 (the packer regenerates
the file, which was wiping the hand edit each round); machines without
Steam credentials fall back to TCP cleanly.
