    "possible_model_reasoning": [
        "The satchel silhouette, double handles, detachable strap, and front clasp do not provide a sufficiently specific match to a documented Coach model without a creed, style number, or wordmark.",
        "The absence of a visible Coach identifier and the generic modern construction make a non-Coach fashion satchel more likely than a vintage Coach bag.",
        "Condition appears Good to Very Good: visible creasing and surface wear on the exterior (photos 2 and 4), while the interior appears intact but has light marks (photo 1)."
