B provides a drawing at 141 mm: HOLD for mismatch explanation; do not average. C supplies matching geometric fields: eligible for the NEXT product-evidence stage, not automatically approved for safety, function or production. These invented candidates are not reviews of actual suppliers. FICTIONAL EXERCISE 2: DOCUMENT IDENTITY Offered unbranded SKU X comes with another maker's genuine approval for SKU Y. Record document/product mismatch. Hold X until its own relevant evidence exists. An authentic document can be irrelevant; do not call it fraud without evidence.
