The Pi presents NCM Ethernet and ACM serial from a configfs gadget, started by robot-usb-gadget.service before networking. usb0 gets 10.55.0.2/30 with no gateway through netplan, matched by interface name: a MAC match turns into PermanentMACAddress= in networkd, which a gadget interface does not have, so it stayed unmanaged. talos reaches the Pi at 10.55.0.2 (ping ~2.4 ms, SSH works) through a NetworkManager profile, host/omarchy/robot-usb-link.sh, matched by the gadget's fixed host MAC. Also clamp the face's tunable parameters (focus sets a blur radius, persistence divides) and fps, after a review flagged unvalidated node parameters.
