These CSVs are cleaned figure-level source data.
The ahead overpressure columns are recomputed from raw centerline profiles using p0=101325 Pa and the 10-mm window [x_center, x_center+0.010 m].
The original pressure_screening.csv files are retained under 02_raw_processed_cases/.../diagnostics as intermediate extraction files, not as the preferred final source for delta_p_ahead.
