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
- Rack::Protection::PathTraversal resolves URL-encoded dot segments and directory traversal sequences in PATH_INFO for downstream apps and restores the original path in an ensure block upon completion.
- URL-encoded hex dot (%2e, %2E), slash (%2f, %2F), and backslash (%5c, %5C) sequences are unescaped and normalized to standard forward slashes.
- Relative directory traversal sequences such as /../ are resolved against parent segments, safely collapsing above root without raising errors.
- Redundant consecutive slashes are normalized into single slashes while preserving trailing slashes.
- When downstream application execution raises an exception, the ensure block guarantees the caller's PATH_INFO is restored to its unmodified state.
- Empty or nil PATH_INFO values pass through without modification.
