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.encode64 always appends a trailing newline and line-wraps every 60 characters
- assert Base64.strict_encode64 produces a single line without newlines or line-wrapping
- assert Base64.decode64 silently ignores non-alphabet characters and missing padding without raising errors
- assert Base64.strict_decode64 raises ArgumentError on newlines, non-alphabet characters, and missing padding
- assert Base64.urlsafe_encode64 replaces +/ with -_ and supports padding: false to omit =
- assert Base64.urlsafe_decode64 decodes both padded and unpadded URL-safe strings while rejecting + and /
- assert Base64 decode methods always return ASCII-8BIT binary encoded strings
