Abstract
A new goniometric device for spectro-polarimetric BRDF measurements is under development. This goniometer will measure linear and circular polarization of materials. Different instrument quality tests were realized in order to identify factors affecting the measured spectra and to obtain functional relationship between the instrument output and the real reflective properties of the materials. The most limiting of all factors influencing measured spectra was the polarization sensitivity of the spectrometer. Moreover, optical fiber bundle connected to the spectrometer input has unpredictable behavior in polarized light. In this paper, we present the artefacts produced by sensitivity of the spectrometer to the polarized light and describe the adequate measurement procedure to maintain instrument response under control and to acquire reliable BRDF measurements.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
