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
- ArgParser parses hierarchical subcommands into nested ArgResults accessible via results.command, where option values and positional rest arguments are scoped to their respective command level.
- assert top-level ArgResults has null name and results.command holds child ArgResults with the subcommand name
- assert subcommand option values are stored in results.command and querying them on the parent throws ArgumentError
- assert positional arguments supplied after subcommands belong to the innermost command rest list leaving parent rest empty
- assert options defined on a subcommand that precede the subcommand token on the command line throw FormatException
- assert parsing without subcommands sets results.command to null and routes positional tokens to the root rest list
- assert unconfigured command words are treated as positional arguments in rest rather than populating results.command
