    "negative_evidence": [
        "photo 1: The exterior is glossy reptile-embossed\/patent material rather than the smooth or pebbled glove-tanned leather typical of classic vintage Coach.",

        "photo 3: The bottom shows glossy embossed material and construction inconsistent with a typical unlined vintage Coach classic.",
        "photo 4: The strap and body appear to use glossy embossed material rather than Coach's usual substantial glove-tanned leather.",
        "photo 6: No legible Coach wordmark, horse-and-carriage emblem, creed patch, or hangtag is visible."

        "The visible construction is more consistent with a generic vintage-style reptile-embossed handbag than a Coach bag.",
        "No Coach identifier is visible in the provided photos; silhouette and gold-tone hardware alone are insufficient for attribution."

        "lining_description": "photo 2: Beige smooth synthetic-looking lining with one interior zip pocket; no label is visible.",
        "strap_construction": "photos 1, 4: Long adjustable shoulder strap in matching glossy embossed material, attached with gold-tone rings and buckle hardware; visible wear and creasing are present.",

    "possible_model_reasoning": [
        "No Coach model is supported. The framed top, glossy reptile embossing, and compact shoulder-bag proportions do not closely match the listed classic Coach glove-tanned models.",
        "Condition: Good; photo 4 shows strap wear and creasing, while photos 1 and 3 show surface wear and edge rubbing. The interior is shown but branding details remain insufficiently close."
