"""Post-install checks: backup_system_file ran during a real install.

Expansion coverage (P4). The unit suite (tests/backup-system-file/) covers the
helper's logic; this confirms it actually fires end-to-end — archsetup leaves a
<file>.archsetup.bak next to each pre-existing file it edits in place.

These targets are edited unconditionally on every run (pacman.conf/makepkg.conf
always sed'd, sudoers always appended, mkinitcpio.conf HOOKS on non-ZFS), so
their backups must exist. Conditionally-edited files (locale.gen, geoclue,
fstab) aren't asserted here since their edits depend on the base image.
