Detailed Description

Accuracy of the Chebyshev3D evaluation kernel.

Guards Chebyshev3DCalc::Eval / chebyshevEvaluation1D (the Clenshaw recurrence that dominates magnetic-field evaluation in track extrapolation). We build an in-memory parameterization of a known smooth function and check that Eval reproduces it to the requested precision over many random points, and that the per-dimension and double-precision overloads agree with the float vector overload. Any breakage of the recurrence (e.g. a wrong FMA regrouping) makes the reproduction error explode and fails the test.
