    "possible_model_reasoning": [
        "No Coach model is a reasonable match at this probability. The small structured flap satchel with top handle and detachable crossbody strap is a generic modern design, not sufficient to identify it as a Willis, Court, or other Coach style.",
        "Condition: appears New based on the seller's description and promotional photos; actual wear, odor, and long-term material condition cannot be verified from stock-style imagery."
