Abstract
<p>The Rosedale Overhead is a 77m long two-lane crossing of BC’s Highway 9 over a busy railway track. Built in 1956, the current improvements include widening, new barriers, seismic retrofit and structural rehabilitation, including full concrete deck replacement. The initial design considered retaining and over-coating the existing girders. However, the final design was the outright replacement of the existing girders, with the new girders configured as continuous spans. This concept was preferred because of the lower costs, a savings partly attributed to the reduced number of girder lines from eight to five and bearings by more than half. A reliable seismic load path was established by infilling the bents either side of the rail tracks and locking the bridge ends with new semi-integral abutments. All other bents were left un-retrofitted with low-friction PTFE bearings to reduce lateral bent demands and avoid foundationupgrades.</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
