Abstract
<p>The Burlington Bay Skyway was built in 1954 and rehabilitated in the 1980s. A continuous three span truss rises from below the deck up over the roadway across the 151 m central span over a navigational channel into Hamilton Harbour. The deck system hangs from the truss and the consequences of a hanger impact could be severe and include prolonged closure, impediment of the navigation channel, and could trigger a progressive collapse of the suspended deck system arising from simply supported stringers and floor trusses. The regional economic impact of bridge closure on one of Ontario’s major arteries is considerable.</p><p>The Ontario Ministry of Transportation (MTO) is adding redundancy trusses to transfer the load from the deck system to adjacent hangers in the event of hanger loss. Each truss runs longitudinally below the edge of the deck through the main span, within the depth of the existing transverse floor trusses. The proactive retrofit improves redundancy of the deck system and keeps the bridge serviceable and safe after hanger loss, in-line with current code requirements.</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
