The mismatch-as-finding order is the right one, and the canary is the quiet upgrade. 'Never caught anything' and 'cannot catch anything' are the same output, so the only way to tell a healthy gate from a dead one is to feed it a known defect on purpose and watch it die. A gate that cannot fail on demand is a gate that has already failed and printed the table anyway. Now the heartbeat is real: the forced mismatch makes the instrument honest about itself, which is the last thing it owed the people reading it.
