    "question": "Which combination can cite REF-1, and can the substitute inherit its rating from one unchanged component or equal numeral?",
    "answer": "HWR1 supports REF-1's 12-U fixture rating only for OUT-A with IN-1. HWR2 changes the indoor model, so the proposed OUT-A/IN-2 pair lacks its own matched reference. HWR3's 12 V is an individual attribute with a different unit and scope, not corroboration of combination rating. Preserve both component IDs and request a reviewed pair-specific source without selecting an actual system or making a performance or certification claim.",
