Abstract
Charles Hamilton Mitchell (1872-1941) was a Canadian civil engineer. He graduated with a civil engineering degree from the University of Toronto in 1898. He was City Engineer of Niagara Falls, N.Y. from 1894 to 1901. In 1905, he was the principal assistant engineer of the Ontario Power Company in Niagara Falls, Ontario, and then studied electrical power in Europe in 1906. Between 1906 and 1914, he designed and built hydro-electric power plants across Canada. He was also a consulting engineer to the Dominion Water Power Branch, Department of the Interior, from 1911-1914 and 1919-1920. In 1919, he was appointed Dean of the Faculty of Applied Science and Engineering at the University of Toronto, a post which he held until his retirement in 1941. In addition to this role, he served on a joint Canadian-American board of engineers studying the St. Lawrence Waterway Project (1924), was a member of the Canadian Society of Civil Engineers (serving as vice-president from 1920 to 1923 and president in 1929), the Institution of Civil Engineers of Great Britain, the American Society of Civil Engineers, and became the first president of the Association of Professional Engineers in Ontario in 1922.

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.
