Abstract
Abstract The food environment in low-income communities may be attributable to the increased prevalence of diet-related chronic diseases. The purpose of this study is to describe the key features of urban food stores. For our descriptive study, 13 corner store owners and 4 supermarket managers were interviewed. Most urban corner stores had closed-store layouts, limiting accessibility to foods. Foods stocked at the corner stores included canned foods, soda, and chips; low-fat, low-sodium, and fresh produce were rarely available. Limited shelf space and a lack of a variety of healthy foods in wholesale stores were mentioned as barriers for stocking healthy foods. Corner stores are a potential venue to improve the food environment, and tailored interventions at multilevel focusing on store owners, wholesalers, and customers are urgently needed.

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
