Abstract
Introduction I went to OPCN for the first time in 2009 to do a household food security survey as a part of my research work at the University of Manitoba. The survey results revealed that OPCN had a high food insecurity; children were surviving on junk food because of limited access to a healthy diet. When I came to Canada a decade ago for graduate work, I came with a stereotypical "romantic" impression of North America, which was built from popular TV shows - beautiful houses with trimmed lawns, clean neighbourhoods, children making snowmen in winter, no slums, poverty or hunger, and abundant resources, which are distributed evenly to all, or at least better than my country. Since my father died because of a doctor's mistake, my mother used to avoid doctors and relied on herbal medicines if we were sick.

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.
