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
- assert aws4.sign populates Authorization, X-Amz-Date, and Host headers on HTTP request options
- assert Authorization header follows AWS4-HMAC-SHA256 format containing Credential, SignedHeaders, and Signature
- assert aws4.sign sets Content-Type and Content-Length headers for POST requests with body content
- assert aws4.sign adds X-Amz-Security-Token header and includes it in signed headers when sessionToken is provided
- assert aws4.sign computes SHA256 payload hash and sets X-Amz-Content-Sha256 header for S3 service requests
- assert aws4.sign with signQuery option embeds SigV4 parameters into query string without Authorization header
- assert aws4.RequestSigner resolves service name and AWS region automatically from amazonaws.com hostnames
- assert aws4.RequestSigner exposes canonicalString, stringToSign, and signature generation methods
