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
- Leaving field_validator mode unset defaults to 'after', running after core type coercion; inputs that fail core type coercion raise ValidationError before the after-validator executes.
- Configuring mode='before' allows intercepting and sanitizing raw, uncoerced inputs before Pydantic core type coercion and constraint validation.
- Configuring mode='wrap' passes the raw value and a wrap handler, enabling custom preprocessing, validation error interception or recovery, and postprocessing.
- Configuring mode='plain' replaces core validation entirely, allowing custom return types without executing Pydantic internal coercion.
- ValidationInfo.data exposes only sibling fields defined before the current field in model definition order; downstream fields are absent.
