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
- Configure request payload size limits in axum using DefaultBodyLimit to prevent automatic 413 Payload Too Large rejections on buffering extractors (Bytes, String, Json) at the default 2MB boundary, override limits per route or sub-router, and stream unbuffered raw requests without limits

契约
- assert buffering extractors (Bytes, String, Json) enforce an implicit 2MB (2,097,152 bytes) limit by default
- assert a 2,097,152 byte payload succeeds with 200 OK on default routes
- assert a 2,097,153 byte payload fails with 413 PAYLOAD TOO LARGE on default routes
- assert malformed JSON exceeding 2MB returns 413 PAYLOAD TOO LARGE instead of 400 Bad Request or 422 Unprocessable Entity because body limit check precedes deserialization
- assert the 413 rejection returns Content-Type text/plain; charset=utf-8 with body 'Failed to buffer the request body: length limit exceeded'
- assert route-level DefaultBodyLimit::max overrides router-level limits to accept larger payloads
- assert route-level DefaultBodyLimit::disable allows arbitrary payload sizes without 413 rejection
- assert DefaultBodyLimit::max(0) accepts 0-byte bodies with 200 OK but rejects 1-byte bodies with 413
- assert unbuffered raw Request streaming extractors bypass DefaultBodyLimit without requiring disable()
- assert nested sub-routers enforce their own DefaultBodyLimit independently of parent router limits
