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
- originalPositionFor resolves 1-based line and 0-based column to source file, 1-based original line, 0-based original column, and name identifier when mapped.
- originalPositionFor returns name: null when the mapped segment does not contain a name index.
- When needle column falls between segments, bias GREATEST_LOWER_BOUND chooses the preceding segment and LEAST_UPPER_BOUND chooses the succeeding segment.
- Queries for unmapped lines or positions before the first segment return an object with all null properties instead of throwing.
- TraceMap parses both encoded VLQ mapping strings and decoded segment arrays for originalPositionFor lookup.
