Abstract
RZ Com (GSC 1990(GSC -2841) is a short period (P = 0.3385 d) W UMa-type binary system, type-W, which has had, over the years, two spectroscopic and numerous light curve studies. The various mass determinations show a large scatter. Here we present the results of new light curve and radial velocity observations, and a fresh analysis by the Wilson-Devinney 2003 code. We have been able to obtain a unified model for photometric five datasets, each used one or more filters. The main model parameters such as mass ratio, temperature, potential, and inclination were in close agreement, as were derived quantities such as mass, stellar radius, etc. Only the spot parameters differed, as one might expect. Further, we determined a distance estimate, r = 204 5 pc, in good agreement with the Gaia value of r = 203.1 3.7 pc. We also presented four new eclipse timings, performed a renewed period analysis attaining a LiTE fit. With that we determined a rate of intrinsic period change dP/dt = 3.86(2) 10 -8 days/year, and-assuming conservative processes-a rate of mass exchange dm1/dt = -4.1(3) 10 -8 M/year which means that the less massive star is losing mass to its companion.

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
