    "possible_model_reasoning": [
        "photo 1: No Coach model is a close enough match to name; the embellished brown handbag appears generic rather than a City Bag, Court, Willis, Dinky, or other cataloged vintage Coach style.",
        "photo 1: Seller states 'Never used,' but condition cannot be fully graded because the interior, bottom, and hardware details are not shown. Visible material has uneven shading and creasing; provisional condition is Very Good, subject to inspection."
