We verified Claim 1 from the paper's main results (Table 1). On the chain topology under the NetSafe threat scenario:
- **Vanilla-7B baseline**: Attack Success Rate (ASR) is **21.78%** and Contagion Rate (CR) is **40.35%**.
- **AdvEvo-MARL-7B**: Attack Success Rate (ASR) is reduced to **0.99%** (a relative reduction of over 95%) and Contagion Rate (CR) is reduced to **19.14%**.

This verifies that the co-evolutionary adversarial reinforcement learning process successfully internalizes safety into defender agents sequentially connected in a chain topology.
