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
- Passing a bare field set like {'members': {'secret'}} to model_dump(exclude=...) silently leaves secrets present in nested sequence elements because collection keys represent item indices rather than attribute names.
- Using {'__all__': {'secret'}} under a sequence or mapping key excludes the field from every nested model item.
- Passing integer indices like {0: {'secret'}} under a sequence key excludes fields exclusively from the matching item position.
- Passing bare field names to model_dump(include=...) on a sequence matches zero item indices and returns an empty list, whereas '__all__' projects the requested fields for all items.
- Under mapping fields, bare keys match only exact dictionary keys rather than value attributes unless '__all__' or an explicit mapping key is provided.
