The shell tests under linux_configuration/tests/ never ran anywhere:
no workflow executed them, so they rotted silently. Three referenced
script paths that moved under scripts/periodic_background/ in an
earlier reorganisation, and test_android_guardian_service.sh created
its temp worktree at a different path from the one it copied into, so
its cp could never succeed.
The new workflow runs the bats suites plus an explicit allowlist of
side-effect-free tests. Roughly eight others drive pacman, /etc,
systemd or adb and need root plus an Arch container, so they stay out.
Repairing the paths uncovered two genuine failures, deliberately left
out of the allowlist because they look like real regressions in the
scripts they cover rather than stale assertions:
- test_music_parallelism.sh expects idle mode to wait
IDLE_CHECK_INTERVAL (30s); the daemon waits 15s, so it wakes twice
as often as intended when idle.
- test_usage_monitoring_installer_efficiency.sh expects the logger
template to sleep between day-rollover checks.
Both need a fix in the covered scripts, not in the tests.
