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
- z.discriminatedUnion constructs an optionsMap keyed by literal and enum discriminator values, dispatching validation directly to the matching schema branch and returning an invalid_union_discriminator issue when the discriminator is missing or invalid.
- Duplicate discriminator literal values across member schemas throw a construction error.
- Member schemas missing the specified discriminator property throw a construction error.
- Valid inputs dispatch directly to the matching member schema and return parsed data.
- Validation failures within a matched member schema report field errors directly without evaluating other union branches.
- Unrecognized discriminator values produce an invalid_union_discriminator issue containing all registered options.
- Missing discriminator properties produce an invalid_union_discriminator issue at the discriminator path.
- Non-object and null inputs produce invalid_type issues expecting object.
- Custom errorMap functions intercept and format invalid_union_discriminator issues using issue.options.
