Abstract
Replacing the deck of the three-lane Lion's Gate Bridge, crossing the Burrard Inlet in Vancouver, BC, involved complex engineering decisions and improvisations to account for the 1938 structure's original design, which didn't allow much more capacity without new improvements. After considering building a movable truss to replace the deck in segments while reopening the bridge to traffic each morning, engineers realized it might not tolerate the load that the bridge's owner, the British Columbia government, demanded. Instead, they turned to traveling jacks. Every morning the bridge had to be restored to road-worthiness for some 45,000 daily vehicles. At night, tolerances were so slim, contractors had to count how many workers were on the structure to make sure its load-bearing capacity wasn't exceeded by all the equipment used in repairs. Seismic upgrades were also done on foundations, including movable plates to allow support beams to bend and not break. Structural repairs were completed at the end of 2000. Final paving is set to be done by spring 2002.

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
