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
- Boolean evaluation of an undefined variable in an if condition raises UndefinedError under StrictUndefined instead of evaluating as falsy
- Accessing a nested attribute on an undefined parent raises UndefinedError even when piped to the default filter under StrictUndefined
- Piping a top-level undefined variable directly to the default filter returns the fallback value without raising UndefinedError under StrictUndefined
- Accessing a missing attribute on a defined dictionary returns the fallback value when piped to the default filter under StrictUndefined
- Testing an undefined variable with the is defined test returns False without raising UndefinedError under StrictUndefined
- ChainableUndefined permits chained attribute lookups on undefined parents to resolve through the default filter
