    "Single-user browser storage is localStorage. The Device tab can explicitly write device profiles and settings; local history and scale memory are different stores.",
    "The reviewed README and package manifest give no project license, and no root LICENSE file was present at the pinned commit.",
    "Device compatibility and formula accuracy are project claims."

    "单用户浏览器数据保存在 localStorage。设备页可由用户明确操作后写入设备档案和设置；本地历史与秤内存是不同存储。",
    "所审阅 README 和软件包清单未给出项目许可证，固定提交的根目录也没有 LICENSE。",
