# int_lap_anomaly_flags

> Anomaly detection flags for data quality control.

<Note>Part of the [Residual](/transform/families/residual) family.</Note>

Anomaly detection flags for data quality control. One row per lap. Uses trailing-7-lap MAD (median absolute deviation) to classify anomalies robustly (cliff, mistakes, event-driven, conditions, normal).
