Contrat

• 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
