        "photo 4: Back is entirely bead-covered and has no visible wordmark, creed patch, or Coach hangtag.",

    "possible_model_reasoning": [
        "The curved, small shoulder-bag silhouette is generic and does not closely identify a Coach catalog model.",
        "Seller describes the item as Y2K and beaded; that is consistent with a modern\/early-2000s fashion accessory, but seller text is not photographic evidence.",
        "Condition: Good to Very Good; beadwork appears substantially intact in the shown views, with a slightly bent strap noted by the seller. Interior, bottom, and attachment points are incompletely assessed."
