        "photo 4: No brand identifier is visible; authenticity cannot be established from these photos."

    "possible_model_reasoning": [
        "photo 1: The compact rounded zippered form is consistent with a coin purse, but it does not match a recognizable Coach model.",

        "photo 1: Condition appears Good to Very Good overall, with visible nap variation, surface marks, and uneven decorative stitching; the interior and odor cannot be fully assessed."
