slv.measurements.mobile.obs.SLOPE_TOL: float | None = 0.05

Calibrated rows whose slope CH4d_m deviates more than this fraction from the day’s median slope are dropped. One bad reference period (a restart with air still in the line, a dying tank) is interpolated over the next hour by the pipeline’s single-tank calibration; the ±100 ppm tolerances never catch it (measurements/trax/record/outputs/trax_cal_audit.txt).
