Abstract
The objective of this article is to establish baseline concentrations of Ba, Cr, Cu, Ni, Pb, Sr, V, and Zn (aqua regia-extractable) in natural surface soils of the Torrelles Municipal District and to investigate the relationships between these elements and soil properties and between the element concentrations themselves. Upper baseline concentrations of these elements were (mg kg −1): Ba 272.6, Cr 40.8, Cu 31.0, Ni 29.9, Pb 68.1, Sr 83.0, V 49.7, and Zn 132.7; most corresponded with the values reported in the literature. Correlation analysis showed that total Fe and Al have the strongest relationships with trace elements.

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
