Abstract
Terrestrial plant and soil carbon stocks are critical for regulating climate change, enhancing soil fertility, and supporting biodiversity. While a global-scale decoupling between plant and soil carbon has been documented, the hotspots and interconnections between these two carbon compartments across Africa, the second-largest continent on the planet, have been significantly overlooked. Here, we have compiled over 10,000 existing soil organic carbon (SOC) observations to generate a high-resolution (250 m) map illustrating the distribution pattern of soil organic carbon in Africa. The SOC map is then used as an input to understand the soil and plant carbon interconnections of Africa's vast landscape under changing environmental conditions. Keywords: Africa | Landscapes | Soil Nitrogen | Soil Organic Carbon (SOC) | Spatial Scale | Above-ground Carbon | Below-ground Carbon Below are R codes and maps, either generated or used in the study.

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
