com.andrew.board-restart-once — INTENTIONAL ONE-SHOT (not shipped in launchagents/)

Install_Fort_Knox_Boot does not install this label. restart_board_once.sh unloads and
deletes ~/Library/LaunchAgents/com.andrew.board-restart-once.plist after one run.

No KeepAlive. No permanent agent. If you need a one-shot restart, copy a RunAtLoad-only
plist (no KeepAlive) into ~/Library/LaunchAgents/ that execs restart_board_once.sh;
the script will remove the plist when done.

See out/FULL_WALK_AUDIT_20260916.md soft-miss fix note (2026-09-16).
