    "possible_model_reasoning": [
        "photo 1: the tapered zip-top crossbody shape is a generic shoulder-bag design and does not closely identify a catalogued Coach model",

        "No visible identifier supports dating; the modern-looking textile strap and hardware suggest modern (2000s+) non-Coach construction"
