    "scope": "Usage is what the source tool recorded per attempt, averaged over cases present in both runs; missing values stay unknown and are never counted as zero. EvalArc does not price tokens. Token counts from different models use different tokenizers and prices, so compare recorded cost when models differ. Durations are the tool's own timing (Inspect sample working time, promptfoo provider latency, JUnit test time); a JUnit duration measures the test, which may not include the agent. Ratios come from single runs and carry no interval."
