    "possible_model_reasoning": [
        "No credible Coach model match is supported: the bag has fixed double handles, a rectangular flap, and decorative folded tabs rather than a catalogued classic Coach turnlock design.",
        "The visible fabric-lined interior and small rectangular clasp components do not establish Coach manufacture and are more consistent with a generic vintage leather handbag.",
        "Condition: Good to Very Good; exterior appears intact with light surface wear, while the interior lining shows noticeable dust\/marks in photos 5-6. Bottom, corners, and odor are not fully assessable."
