Scope: one forward spectrum on the 755-776 nm, 701-output-wavelength validation route.
The current retained trace is:
low-overhead prepare_o2a 0.057938 s
low-overhead forward elapsed time 1.108574 s
phase-timed forward elapsed time 1.192873 s
high-resolution radiance samples 3,874
LABOS Fourier terms 120,390
LABOS layer visits 5,417,550
doubling steps 8,389,666
The forward elapsed time is not dominated by writing 701 output values. The instrument response expands those output wavelengths into 3,874 high-resolution radiance samples. Each sample builds wavelength-specific optical input and runs LABOS Fourier transport.
