+
+Key research validating our design:
+- **ARTEMIS** (arXiv:2512.09882): First live enterprise AI vs human pentest — AI has high FP rates. Our escalating FP penalty and honeypot system directly address this.
+- **MAPTA** (arXiv:2508.20816): Multi-agent pentesting achieves 76.9% on SSRF/misconfig but 0% on blind SQLi — our three-tier output tests exactly this reasoning gap.
+- **Reward Machines** (arXiv:2405.15908): Phase-decomposed rewards accelerate RL training — our environment tracks audit phases (reconnaissance → enumeration → exploitation → reporting).
+
+**SecurityAuditEnv is the only compliance-aware security benchmark** that maps vulnerability findings to real compliance framework controls (PCI-DSS requirements, SOC2 trust service criteria).
