BrowserAgent Adversarial Co-Evolution — LoRA adapters
LoRA adapters (r=16, alpha=32) over TIGER-Lab/BrowserAgent-RFT (Qwen2.5-7B) from a 6-iteration adversarial co-evolution loop on multi-turn web form-filling tasks. An ADVERSARY learns to prompt-inject a frozen world model to derail a web EXECUTOR; both update each iteration (reactive attack: injection lands on the page the executor's action produces).
Adapters
exec_v1…exec_v6— the EXECUTOR (defender) at each iteration.adv_v1…adv_v6— the ADVERSARY (attacker) at each iteration.

Key results (harder-100 multi-turn benchmark, exact-match)
Under the strongest adversary adv_v6 (3 seeds): clean capability rises across iters
(0.70 -> 0.95, peak exec_v5), but adv_v6 floors every executor to ~0.15-0.22 under attack —
co-evolution converged to a dominant adversary. Best executor = exec_v5 (0.950 clean /
0.217 attacked). Under the weaker adv_v3, exec_v2 held 0.516 attacked.
