+# Unit tests for build-aur.sh — the AUR local-repo build helpers.

+# Only the pure, side-effect-free helpers are unit-tested here. The
+# build_aur_packages orchestrator clones from the AUR, runs makepkg as
+# $SUDO_USER, and needs root + network, so it is exercised by the build
+# integration test and the manual verification checklist, not bats.
