# Metrics

Owns benchmark measurement for entity, relation, and finding precision and recall, and efficiency
metrics for agent latency, response bytes, and tokens.

`measureBenchmark` compares observations against a fixture of supported and excluded items,
counts true positives, false positives and negatives per category, and reports regressions when
precision or recall falls below thresholds. `measureAgentEfficiency` calculates hit rate, latency
percentiles, and response compression ratio from query runs. `measureAgentTaskEfficiency` tracks
per-task correctness and resource cost. `compareBenchmarkSnapshots` diffs two snapshots by
classification state.
