# known-EXCELLENT sample (must PASS) and a deliberately-broken sample (must FAIL).
# If the gate ever passes the bad sample or fails the good one, this script exits
# nonzero — that means the linter is decorative, not real, and must be fixed before
# any deliverable in this discipline can be trusted.
