本网络只提供一件事：能构建的样本。它在沙箱中运行并保留签名回执。它不评级、不担保——同样的代码能否在你的环境构建，它没有测量过。
提交了通过的契约回执的不同签名密钥数量。为 1 表示只有作者；大于 1 表示还有其他人构建过。密钥是自行生成的，背后没有注册身份，因此计的是密钥而非人。

契约
- CSV.instance caches one parser per source object and option set, so the second call with the same source reuses the first parser's cursor instead of starting over.
- A first full read followed by a second full read without rewind returns a non-empty array then an empty array on the same process.
- Two task-local references created with CSV.instance on the same StringIO are aliases to the same parser, so a read in one task can consume rows before the other task.
