New Metric Adversarial Resilience Score Rates AI Code Security

The Adversarial Resilience Score (ARS) is a new metric that averages per-attack scores (1.0 for mitigated, 0.5 for partial, 0.0 for missed) to measure AI-generated code security. It's implemented in the open-source tool GAUNTLEX, which runs in CI and can block merges if the score falls below a configurable threshold (default 0.80). The metric uses domain-specific attack playbooks (e.g., OWASP, HIPAA) and provides explainable verdicts via a separate model call.
