A real radix-2 Cooley–Tukey FFT runs on a 1024-sample Hann-windowed vibration buffer every frame (4096 Hz simulated sample rate). The anomaly detector tracks the energy at the outer-race ball-pass frequency (BPFO) against a rolling baseline and flags a fault when its z-score sustains above threshold.
