    "possible_model_reasoning": [
        "No Coach model is a reasonable match; the proportions, flap construction, side gussets, and strap-and-clasp details are Birkin-inspired rather than matching the catalogued Coach silhouettes.",
        "The visible interior lacks a Coach creed or other identifier, while the exterior has no Coach branding.",
        "Condition appears Like New or Mint based on photos 1-7: clean leather, intact structure, and little visible wear; interior and odor cannot be fully assessed."
