Abstract
Africa is rapidly urbanising and urban food systems are being transformed. Some have argued that this transformation is driven by a supermarket revolution akin to that in North America, Europe and Latin America. Others suggest that the supermarket revolution model oversimplifies complex African realities and that urban food systems are experiencing uneven supermarket penetration in the face of resilient informal food sectors. This paper focuses on Windhoek, Namibia, showing that the city’s food system is dominated by South African and local supermarket chains. Since the end of apartheid, South African supermarket chains have expanded their operations into Namibia. Supermarket domination of Windhoek’s urban food system is a function of proximity of South Africa and integration into South African supply chains. In other African countries, supermarket penetration has been much slower and is even being reversed. Explanations for uneven penetration in different countries require greater contextualisation and more case study research.

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
