Abstract
When you hear “Mushroom Bridge”, you may very well think of Mario Kart. But it is also the nickname of a portion of the Crane Road Bridge, a nearly century-old crossing in north suburban New York City. Comprising two bridges, it carries the Bronx River Parkway through a forest preserve in the Village of Scarsdale and the Town of Greenburgh in Westchester County. The southern bridge is a multi-span concrete bridge (the Mushroom Bridge portion) that crosses the Bronx River, while the northern bridge is a single-span steel through-girder bridge that crosses the two-track Metro-North Railroad Harlem Line (accordingly called the MNR Bridge). In this project, the historic bridges are replicated to preserve the community while improving pedestrian use, access and enhancing the roadway geometry.

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
