    "possible_model_reasoning": [
        "The bag does not match a recognizable Coach catalog model because it lacks the leather construction, creed, turnlock, and Coach branding associated with vintage Coach handbags.",

        "Condition appears approximately Very Good: the bag is structurally intact in the photos with no obvious major tears or stains, though close-ups of corners, zipper function, and strap attachment points are limited."
