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
- ArgResults throws an ArgumentError when queried with an alias name via operator [] or wasParsed(), requiring all lookups to use the canonical option name regardless of how the option was supplied on the command line.
- assert parsing --dest assigns the value to canonical key results['target'] with wasParsed('target') true
- assert results['dest'] and results.wasParsed('dest') both throw ArgumentError for option alias
- assert parsing --no-simulate assigns false to canonical key results['dry-run'] with wasParsed('dry-run') true
- assert results['simulate'] and results.wasParsed('simulate') both throw ArgumentError for flag alias
- assert results['filter'] throws ArgumentError for multi-option alias
- assert results.options contains only canonical names and excludes configured aliases
