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
- PersistentPreRun on a subcommand or group completely shadows ancestor PersistentPreRun hooks, executing only the nearest hook and skipping root initialization unless manually chained.
- A subcommand defining only PreRun executes the nearest ancestor PersistentPreRun first followed by its own PreRun.
- When a single command defines both PersistentPreRun and PreRun, PersistentPreRun executes first followed by PreRun before Run.
- When both error-returning (*E) and non-error variants are set on the same hook, Cobra executes the *E variant and silently ignores the non-E function.
- Returning an error from PersistentPreRunE or PreRunE immediately short-circuits execution, skipping Run, PostRun, and PersistentPostRun.
- Returning an error from RunE aborts before PostRun and PersistentPostRun execute, returning the error to Execute.
- Context mutations performed via cmd.SetContext in PersistentPreRun or PreRun are preserved and accessible via cmd.Context in Run and PostRun hooks.
- PostRun executes on the active command before the nearest PersistentPostRun, which is similarly shadowed by intermediate definitions.
