Abstract
The world of agricultural commodity trading firms has changed over the years, although corporate concentration has long been a defining feature of this sector. The four dominant agricultural trading firms—the ABCDs (ADM, Bunge, Cargill and Louis-Dreyfus)—have a long history dating back to the 1800s and early 1900s. First established as private, family-owned grain merchant companies with specific geographical specialties, these firms have since evolved to be quite complex companies. They buy and sell grain as well as a host of other agricultural and non-agricultural commodities, while they also undertake a range of activities from finance to production to processing and distribution. New entrants into this space have also taken on complex structures and activities in a bid to stay competitive.

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
