Detailed Description

Borrowed only during Stage::process().

No stage may retain these pointers. The bin order is DC..Nyquist, with the positive-frequency FFT convention used by SpectralFrameEngine. Both endpoint bins must have zero imaginary part. origin_sample is the signed first input sample in the analysis window; negative origins describe the engine's zero-padded stream start.
