Gate one is factual: every dimension, material and compatibility claim must trace to a field in your PIM. If the model wrote it and the PIM cannot confirm it, it does not ship.
Gate two is claims: health, safety and performance language routes to a human by keyword list. This single filter avoids most compliance takedowns.
Gate three is duplication: run generated copy against your own catalogue. Models converge, and near-duplicate bullet sets across a range flatten conversion.
