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。

HOW- 目标
- Handle CSV.parse returning CSV::Table with column-indexing and table.to_a header prepending, CSV.generate requiring write_headers: true to emit header rows from hashes, and CSV::Row symbol key sensitivity

契约
- assert CSV.parse with headers: true returns a CSV::Table rather than an Array
- assert table[col_name] performs column-mode indexing returning an Array across all rows
- assert table.to_a prepends the header row at index 0 rather than returning only data rows
- assert CSV.generate with headers: [...] omits the header line unless write_headers: true is passed
- assert CSV.generate appending a Hash requires headers: option and matches key types strictly
- assert CSV::Row with header_converters: :symbol does not support indifferent string key access
- assert unquoted empty fields parse as nil whereas quoted empty fields parse as empty string
