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。

- CSV.parse_line
- CSV::InvalidEncodingError

契约
- CSV::InvalidEncodingError inherits from CSV::MalformedCSVError and RuntimeError rather than EncodingError, so rescue EncodingError fails to catch byte sequence errors during parsing.
- assert CSV.parse with invalid byte sequences raises CSV::InvalidEncodingError reporting the 1-based line_number
- assert CSV.parse and CSV.parse_line raise ArgumentError with message 'Cannot parse nil as CSV' when passed nil
- assert CSV.parse_line on an empty string returns nil whereas CSV.parse returns an empty array
- assert CSV.parse with liberal_parsing: true allows unescaped quotes but still raises CSV::MalformedCSVError on unclosed quotes
- assert CSV::MalformedCSVError inherits from RuntimeError and attaches line_number on parse errors
