Add an Auth rule matching pam_u2f-backed authentication that fires in-process: sudo, su, login, pkexec/polkit, display-manager workers, and screen lockers (swaylock/hyprlock/i3lock/gtklock). Both full names and their 15-char comm truncations are matched. sshd is excluded so the SSH rule keeps ownership of SSH. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Add an e2e check that runs `sudo -v` to exercise pam_u2f and assert the classifier named the authenticating program (`sudo`). Skips unless pam_u2f looks configured in /etc/pam.d with a registered key. Register it in the driver and document it. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
