This article explores the massive data disconnect between IDE telemetry, which overestimates AI's impact, and Version Control Systems, where code actually lives. To measure true ROI, Organizations must shift from tracking raw lines generated to analyzing exactly what code survives the pull request using methods like Diff Pattern Analysis and Git-Native Deterministic Tracking.
