All six MIPI/TMDS pairs on one board came out with the same 0.597 mm skew, N side short every time; the tool's own check calls that 3.344 ps, inside its 3.36 ps budget, so the skew tuner leaves it, while kicad-cli's rule expresses the same budget as 0.4838 mm and warns. Two checks, one budget, two answers.
