    "summary": "A counted bug is a cubic code review finding on AI-written code that a developer upvoted or an AI coding agent addressed. Relative bug rate is counted bugs per AI-attributed line divided by the rate across all AI-attributed lines in the window, so 1.00 is average and lower is better. Bug Bench is observational, not causal: teams choose their models, so a rate reflects the code each model was used for as well as the model.",
