Description

When I attempted to use Warp to calculate the one-dimensional Fast Fourier Transform, I noticed that the results given by Warp deviated significantly from those of NumPy, and this deviation increased as the scale of the computational data grew larger.

Attached is the code that can reproduce the problem

Research direction

Start by reading the attached qs_report.txt reproduction and compare its one-dimensional Warp FFT results with NumPy at the reported data scales. Trace the relevant FFT entry point from the reproduction; done means explaining the growing discrepancy and confirming corrected results against NumPy across those scales.
