    "answer": "AM1 requires the complete M20 suffix to distinguish P1 from P2. AM2 leaves that suffix unobservable, so neither selection is supported yet. AM3 identifies P3 with M30-C and provides no compatibility row for either M20 variant. Request a clear suffix or authoritative matching record rather than choosing by shared prefix or appearance. The table supports documentary matching, not an instruction to install a part.",
