DoGNAVY is a joint AI security harness by [deepsec@DARKNAVY](https://deepsec.darknavy.net) and independent security researchers based in Shanghai. In a full CyberGym Level 1 evaluation, it passed 1,369 of 1,507 tasks (90.84%).

This report presents DoGNAVY, an agentic system for vulnerability reproduction, and documents its evaluation on the complete [CyberGym](https://www.cybergym.io/cybergym/) Level 1 task set. DoGNAVY combines reachability analysis, proof-of-concept (PoC) construction, dynamic testing, and independent review in a multi-agent workflow. The system can revise its approach as evidence accumulates, subject to explicit task boundaries and runtime controls.
