    "possible_model_reasoning": [
        "photo 1-6: No Coach model is a plausible match because the bag lacks leather construction, Coach branding, a creed, and Coach-style hardware.",

        "photo 1-6: Condition appears approximately Good to Very Good for a textile bag because the body is intact, but fringe is visibly loose and extensively tangled."
