The checks compare values and all 27 derivative columns with a separate exact-rational rotation chain. They include nonzero calibration, noncommuting rotations, both clock-knot sides, input ownership and rejections. This does not qualify the complete numerical-reference bridge, native propagation, prediction widths or observational confidence. No aircraft data or fits were used.
