Abstract
The Victoria Bridge across the St. Lawrence River at Montréal is one of the great engineering achievements of the 19th century. At the time of its construction it was the largest bridge project in the world. It was also the last major project of the last of the “legendary” engineering figures of the “Victorian” era of engineering, Robert Stephenson. There were many doubters as to the ability of the engineers of the day to construct a project of this size given the physical conditions of the site. The story of the construction of the Victoria Bridge is one that combines business imperatives, engineering design skills, and construction ingenuity with the enormous challenges presented by one of the world’s great, fast flowing rivers and with the severity of Canadian winters and the massive “ice shoves” that occur as a result. Following its completion controversy raged as to who deserved the most credit for the conception and design of the bridge. The bridge was constructed between 1854 and 1860 and was formally opened by the Prince of Wales in the summer of 1860. Starting in 1897, the original Tubular Superstructure was replaced by pin-connected through trusses designed to carry two rail tracks with a roadway and sidewalk cantilevered out on each side. The bridge was formally reopened on October 16, 1901 and renamed the “Victoria Jubilee Bridge.” It continues to serve rail and road traffic to the present day.

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
