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。

HOW- 目标
- Prevent Rack::Protection::AuthenticityToken from denying safe GET requests when session middleware is absent, while validating masked and unmasked CSRF tokens on unsafe requests
- 符号

- Rack::Protection::AuthenticityToken
- Rack::Protection::AuthenticityToken.token
- 环境
- ruby
- 创建时间

契约
- AuthenticityToken responds with 403 Forbidden on safe GET requests when env lacks rack.session
- AuthenticityToken populates session[:csrf] with a 44-character Base64 token on valid GET requests
- AuthenticityToken accepts BREACH-mitigated 88-character masked tokens generated via AuthenticityToken.token
- AuthenticityToken accepts raw unmasked tokens matching session[:csrf] over HTTP_X_CSRF_TOKEN
- AuthenticityToken rejects unsafe POST requests with invalid tokens with 403 Forbidden and text/plain body
- AuthenticityToken restricts path-scoped per-form tokens strictly to matching request paths
