Your question is Safety-First Planning Metrics. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
What metrics do you prioritize when evaluating a Planning model that must prioritize safety over aggressive navigation?
Explain how you would evaluate planner outputs using logged trajectories or simulation episodes. Identify primary safety metrics, secondary efficiency metrics, suitable aggregation methods, and how you would select operating thresholds or compare model versions. Include a practical evaluation implementation and describe how you would handle rare safety violations.
