Abstract
<p>The Seal Island Bridge is a steel through-arch truss bridge in Cape Breton Island, Nova Scotia, Canada with a main span of 152 m over navigable waters. At over 60 years in service, the bridge is near the end of its design life and showing structural and operational difficulties such as a previously failed truss diagonal, the presence of tack welds throughout the structure, cracked floorbeams and wind- induced vibrations. As a part of this study, a series of detailed and focused bridge inspections, including structural health monitoring (SHM), were performed to inform the structural analysis. To assess the structure, a finite element (FE) model was created and calibrated using SHM data and the inspection findings. Additionally, a wind buffeting analysis was performed to refine the wind loading for the assessment. Based on the results of the analysis and investigations, a rehabilitation plan was developed to ensure that the bridge could remain in service for an additional 15 years.</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
