Capstone 15 — Constitutional Safety Harness + Red-Team Range
Anthropic's Constitutional Classifiers, Meta's Llama Guard 4, Google's ShieldGemma-2, NVIDIA's Nemotron 3 Content Safety, and X-Guard for multilingual coverage defined the 2026 safety-classifier stack. garak, PyRIT, NVIDIA Aegis, and promptfoo became the standard adversarial evaluation tools. NeMo Guardrails v0.12 ties them into a production pipeline. This capstone wires all of it together: a layered safety harness around a target app, an autonomous red-team agent running 6+ attack families, and a constitutional self-critique run that produces a measurable harmlessness delta.
