[See related article at www.cmaj.ca/lookup/doi/10.1503/cmaj.210083][1] KEY POINTS More than 5 of every 1000 people in Canada will receive a new diagnosis of heart failure this year.[1][2] Many more will have respiratory symptoms that will prompt the ordering of chest radiography.[2][3],[3][4] In a

Not 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.
