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 Plug.Session.init/1 enforces :signing_salt for cookie storage at initialization but defers :secret_key_base validation until runtime, where omitting it or providing fewer than 64 bytes raises ArgumentError only when fetching or writing cookies
- assert calling get_session/2 before fetch_session/2 raises ArgumentError stating the session is not fetched
- assert read-only session inspection never emits a set-cookie response header, while session mutations register a before_send callback to emit signed cookie headers with HttpOnly and path=/
- assert tampered or forged incoming cookie signatures are silently dropped with an empty session map rather than raising a runtime decoding error
- assert configuring :encryption_salt upgrades session payload handling from base64-encoded signed plaintext to AES-GCM ciphertext
- assert configure_session(conn, drop: true) on an active session emits a set-cookie header with max-age=0 to expire the cookie on the client
