Abstract
<p class="1Body">In this study, genotoxic properties of some synthetic acidic dyes were researched by <em>umu</em>-test (<em>Salmonella thyphimurium </em>TA1535/pSK1002) which is a short term bacterial test. The study analyzed genetoxic activity of Acid Blue 127, Acid Orange 51, Acid Black 63, Acid Yellow 17 and Acid Blue 113 synthetic acidic dyes in presence and absence of S9 fraction used in Textile industry. Solutions of dyes at concentrations of 400 µg/ml, 120 µg/ml, 40 µg/ml and 4 µg/ml were prepared; and biotransformation effects of dyes that undergo chemical modifications on organisms were examined by measuring betagalactosidase activity in presence of liver enzymes by using rat S9 fraction. At the mentioned concentrations the absorbance values of betagalactosidase activity were measured for 5 synthetic acidic dyes and none of them showed mutagenic effect either in presence or absence of S9 fraction. In addition, these results mean that these synthetic acidic dyes are not metabolized with liver enzymes.</p>

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
