Abstract
Editorials provide an opportunity for the authors to get ideas out and things off their chests. Between us we have a sobering 70 years of experience working on health, initially in Southern Africa. We watched with horror as the HIV epidemic progressed inexorably in the 1980s through Zimbabwe (where David was based) to South Africa in the 1990s (where Alan worked at the University of Natal). HIV was a new disease but swept through the region with unbelievable speed and ferocity. A survey in Northern KwaZulu-Natal in 1986/87 found no HIV, by 2018 prevalence among pregnant women was over 50 percent.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
