Within the Book III framework, requirements define intent, Usecases define executable scope, the operating envelope defines valid conditions, and the knowledge set supports interpretation. Simulation then tests whether the safety function stays inside those declared boundaries before real-time execution occurs.

This matters because AI-enabled safety functions operate inside complex state spaces. Occupants may move, objects may enter the field of view, sensor conditions may change, and multiple system states may interact at once.

Without boundary enforcement, simulation can expand into another open-ended exploration problem.

With boundary enforcement, Simulation for AI Safety becomes a disciplined engineering tool.

It allows teams to evaluate complex interactions, state changes, and multi-occupant conditions while preserving finite scope. As a result, simulation supports controlled execution rather than uncontrolled possibility.

Book III uses Occupant Sensing as the demonstration platform, but the approach applies more broadly to passive safety, active safety, autonomy, software-defined vehicles, and other sensing-based vehicle functions.
