        "photo 1: large structured Birkin-style silhouette with a lock, clochette, and palladium-tone hardware, unlike the documented vintage Coach model catalog",

        "photos 1-6: absence of any Coach identifier despite extensive exterior coverage materially lowers the likelihood of Coach manufacture",
        "photos 1-6: product-style imagery may not document the actual bag; request seller-specific photos before purchase"

    "possible_model_reasoning": [
        "No Coach model is a reasonable match: the silhouette, closure strap, lock, clochette, and handle arrangement are Birkin-inspired rather than City Bag, Willis, Court, Station, or another Coach catalog style.",
        "The visible H-style zipper marking in photo 3 is not a Coach identifier and conflicts with a Coach attribution.",
        "Condition appears new or unused based on the clean product images, but actual condition is uncertain because the photos may be stock images and the interior is absent."
