Wires scripts/seat-inventory.py --check to a user systemd timer on nh3-dev (09:15 daily, Persistent=true so a missed run fires on next boot) that posts to althing when the committed document stops matching the live box. Alarms rather than auto-committing. A drift means something changed on the HOST, which deserves a human look -- silently regenerating the doc would erase the evidence of when the change happened and why, which is how the char-rp substitution went unnoticed for three weeks. The alarm includes the changed table rows, not just the fact of divergence, so it does not send the reader hunting. ⚠ The post goes --to infra-ops, which is the fleet ops handle the reading session also runs as. That is the documented exception -- a memo from cron to a future session, the same pattern as the Beszel alerts -- so the message says so in its first line, to stop a future session triaging its own alarm as peer mail and trying to reply to it. SuccessExitStatus=0 1 because a detected drift is a deliberate non-zero exit, not a unit failure.
