    "answer": "PRW1 supports G1 and its stated Q property for L1 only. PRW2 supports L2's documented family F but supplies no grade or property finding. PRW3 groups the family without extending L1's grade declaration, so B remains a correct family identification with missing supplier grade evidence. Preserve family, lot and stated properties separately instead of infer material performance or suitability from a common resin code or catalog heading.",
