    "possible_model_reasoning": [
        "No Coach model is listed because the bag lacks a visible identifier and its soft, simple hobo shape is common among many non-Coach makers.",

        "Condition: approximately Very Good based on intact visible leather and stitching, with noticeable creasing and nap variation; interior, bottom, odor, and full corner condition remain unknown."
