    # 批量(命令行多个 id)
    python fetch_eval_record.py id1 id2 id3

    # 批量(从文件逐行,空行 / # 开头跳过)
    python fetch_eval_record.py --file ids.txt

    # 批量(从 stdin)
    cat ids.txt | python fetch_eval_record.py -

    # 自定义输出目录
    python fetch_eval_record.py --out-dir ./samples id1

    # 保留原始 HTML(便于排错)
    python fetch_eval_record.py --keep-html id1

    # 单文件多样本合并(把所有样本写到一个 list JSON 里)
    python fetch_eval_record.py --merged-out all.json --file ids.txt

输出文件命名: <问题前N字>_<id哈希8位>.json  (默认 N=12)
