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
- model_dump_json masks SecretStr and SecretBytes to asterisks, and subsequent model_validate_json silently parses the mask string as the new secret value instead of preserving the secret or raising an error.
- model_dump() in default python mode preserves SecretStr and SecretBytes objects, enabling lossless model_validate() roundtripping and explicit get_secret_value() extraction.
- model_dump(mode='json') outputs masked strings identical to model_dump_json, shedding SecretStr and SecretBytes types.
- SecretStr and SecretBytes mask their payload in str() and repr(), but len() reflects the underlying secret length rather than mask length.
- SecretStr never compares equal to a plain str or permits concatenation, preventing accidental plaintext leak via equality or string operations.
