  "body": "Vulcan runs Arch Linux, which is a rolling release. The package manager is pacman.\n\nKey commands\nInstall: sudo pacman -S <pkg>\nRemove: sudo pacman -Rs <pkg>\nQuery installed: pacman -Q <pkg>\nCheck for updates: pacman -Sy\nUpgrade all: sudo pacman -Syu\nSearch: pacman -Ss <term>\n\nThe build mirror is pinned to reduce drift. Do not change the mirror configured in /etc/pacman.conf without approval.\n\nNTP and time sync\nCheck time state with: timedatectl show\nTime skew causes pacman key validation failures, which will then be treated as your problem.\n\nBuild dependencies\nbase-devel, cmake, and git are pre-installed.\n\nService management\nUse standard systemd tooling: systemctl and journalctl.\n\nArch is rolling release. Package upgrades can break builds. Pin packages that must stay stable using IgnorePkg in /etc/pacman.conf."
