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::FieldInfo provides 0-based column index, 1-based logical line number, and transformed header symbol metadata to custom converters registered in CSV::Converters.
- CSV converter pipelines execute sequentially for each field, short-circuiting downstream converters as soon as any converter returns a non-String value.
- CSV.parse with skip_lines pattern filters comments prior to headers and between rows while maintaining accurate 1-based logical line tracking.
- CSV.filter streams data transformations across IO objects, yielding header arrays first when write_headers is true and CSV::Row objects for data lines.
- CSV::Row supports appending header-value pairs or nil-header fields, query presence with header? and field?, and column deletion returning key-value pairs.
