Abstract
<p>The Angus L. Macdonald Bridge, completed in 1955, connects Dartmouth and downtown Halifax, Nova Scotia, Canada. This suspension bridge is 762 m long, with a 441 m long main span. The deck of the suspended spans reached the end of its functional life and the entire superstructure was replaced segment-by-segment during full weekend and evening closures of the bridge, with traffic using the bridge during weekdays. The new deck segments were fully prefabricated, including an initial thin layer of wearing surface, and erected in a way that allowed traffic to use the bridge immediately following the replacement of an existing deck segment. This paper describes some aspects of the complex fabrication of the bridge superstructure. It further describes how the deck segments were replaced and explains unique challenges encountered during segment replacement and how they were addressed.</p>

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
