DO-178C Traceability: Deterministic Verification in a Probabilistic Age
A flight management system. DAL-A — catastrophic failure condition. Every high-level requirement must trace to a test. Every test must trace back to a requirement. Every condition in every decision must be shown to independently affect the outcome. The FAA doesn't accept "probably correct." They accept "provably correct." And this is where the separation between what AI generates and what scripts verify stops being an architectural preference and becomes a certification necessity.
