Guardrails
Guardrails are the layered deterministic checks you wrap around a non-deterministic model: input validation, output filtering, schema enforcement, confidence thresholds with refusal, and human approval for high-stakes actions. The principle is to put controls you can fully trust around a core you cannot, so the system stays safe even when the model misbehaves.
