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
- Option.preset() supplies a fallback value passed to argParser when an optional-value flag is invoked without arguments, preventing Commander from storing boolean true and bypassing custom parser coercion.
- opts() contains boolean true instead of a parsed number when an optional-value option lacks a preset and is passed without an argument
- opts() retains the default value when the optional-value flag is omitted entirely
- opts() contains the parsed custom argument when the flag is passed with an explicit value
- accumulating option collectors append preset values on valueless flag invocations instead of having the entire accumulated array overwritten by boolean true
- options configured with choices validate against preset values rather than assigning boolean true outside the allowed choices list
