    "possible_model_reasoning": [
        "photo 1-2: No Coach model is a close enough match to name confidently; the silhouette is a generic open-top rectangular tote rather than a clearly identifiable vintage Coach style.",

        "photo 1-2: Condition appears approximately Very Good from the visible exterior, with light creasing and surface marks; interior, bottom, odor, and material condition remain unknown."
