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 Base64.decode64 silently discards '-' and '_' characters, corrupting payloads without raising an error
- assert Base64.urlsafe_decode64 correctly decodes URL-safe payloads containing '-' and '_'
- assert Base64.encode64 appends a trailing newline, causing Base64.strict_decode64 to raise ArgumentError
- assert Base64.strict_encode64 produces single-line encoded strings without newlines
- assert Base64.urlsafe_decode64 decodes unpadded URL-safe strings where Base64.strict_decode64 raises ArgumentError
- assert Base64.urlsafe_decode64 rejects inputs containing embedded newlines
