# Tier — coverage tripwire. Every module the Factory can build must be classified
# below: either smoke-tested headless (SAFE), or explicitly parked as needing real
# hardware/a daemon (HARDWARE, best-effort in state.sh / hardware.sh) or a specific
# compositor (COMPOSITOR). A newly added module that isn't listed fails this job,
# forcing a conscious "is it covered?" decision instead of silently escaping the
# smoke net -- which is how the slider/backlight crash class (#5179) slipped by.
