Abstract
<p>Montreal’s Champlain Bridge was the first large scale use of prestressed concrete in Canada. A lack of understanding of corrosive effects from the long term use of de-icing salts has, over the decades, led to severe corrosion of the concrete girders. A poor drainage system and water infiltration through the pre-stressing anchors contributed to accelerating deterioration. A decision to replace the bridge was taken in 2011 only 49 years after its opening.</p><p>Today, the most vulnerable girders are instrumented and the owner, The Jacques Cartier and Champlain Bridges Incorporated, has installed steel trusses beneath the exterior concrete girders as a risk management strategy.</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
