Tested: the .deb on an Ubuntu 24.04 VM with root, 34/34 checks (packaging/vm-test/kbinstaller.sh): install and legacy migration, dashboard API token and CORS, services on the packaged units with kb-checker left dead, SSH operator console with a live link to kbd, audit chain, sensor under the package.

Not tested: installing the Arch package (pacman -U), kbagents under systemd, reboot persistence, clicking isolate/restore in a browser against a live kbd.

Notes: kb-checker is under maintenance and repairs and stays down unless started by hand. Members of group kb have full control-plane access over /run/kb/kba.sock. The dist/ folder in the repository holds an older build without the sshd/account/socket fixes; use these release assets instead.
