    "possible_model_reasoning": [
        "No Coach model is supported: the bag is a modern generic hobo with a large multi-compartment layout, not a recognizable vintage Coach catalog silhouette.",

        "The seller's faux-leather description and absence of any Coach identifier make a genuine vintage Coach origin highly unlikely."
