Abstract
Abstract CA system model for the Line-of-Sight (LoS) Lambertian radiation pattern has been designed with commercially used high power white phosphorous converted white light emitting diode (PLED) of CCTs 2200K, 3000K and 5700 K and three photodiodes of quite different specifications. This system has been successfully tested for the maximum data rate of 300 Mbps and 170 Mbps for RC constant and electron life time 0.5 ns and 1 ns, respectively. The CCTs 2200k and 3000k irrespective of any particular detector have provided maximum data rates. One CCT 5700K with detector model of S5107 or S7686 for the values 0.5 ns and 1 ns has provided slight lower data rate of 200 Mbps or 150 Mbps, respectively with required BER of 10-6 for stable communication. This CCT 5700 K performance with another detector S5973/-01 has been noticed altogether different and could not sustained the VLC link and signals were not detected by the detector. It is thus concluded that both the CCTs 2200K and 3000K have performed satisfactorily with all the three detectors but one CCT 5700K with combination of detector S5973/-01 found completely mismatched as this could not even establish the link. This CCT 5700 K despite of having higher brightness and transmit power due to lower responsivity of the detector as compared with the other two CCTs supported slight lower data rates. All the three detectors have varied responsivity and other specifications which have affected performance of VLC link. For CCT 5700 K both the detectors, S5107 and S7686 have almost equal responsivity support but the detector S5973/-01 provided slight lesser as compared to other detectors. This exhibited that all the three detectors have varied performance for CCT 5700 K due to dominating in blue wavelength beside other limitations of responsivity and photo sensing area of the detectors.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
