Abstract
In his 1842 Report on the sanitary condition of the labouring population of Great Britain, Edwin Chadwick demonstrated the existence of a mass of preventable illness and premature death in the community caused, he argued, by insanitary physical circumstances.' Although much of the evidence for the existence of this preventable mortality was anecdotal, Chadwick included a chapter of differential class-based death data which dramatically illustrated the extent to which insanitary physical circumstances shortened life. Chadwick's chosen statistical measure-the average age at which a given class of people died showed that what he called the "average period of life" or "chance of life" was as low as 17 for labourers in Manchester but as high as 52 for gentry in Rutlandshire.2 Although his statistics were widely quoted at the time,3 professional statisticians dismissed the data and historians ever since have paid little serious attention to it.4 In this paper I will argue that Chadwick's class-based average-age-at-death data were a central feature of the Sanitary report and that we cannot fully appreciate the argument or even the organization of the report without them.

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
