    "possible_model_reasoning": [
        "No Coach model is proposed because the visible tote lacks a creed, wordmark, carriage, hangtag, or Coach-specific silhouette.",

        "Condition: approximately Very Good based on clean-looking exterior and intact visible structure; interior, odor, and hidden wear are unknown."
