Abstract
Joseph Pennell, one of the greatest lithographers and print-makers in the United States in the first quarter of the 20th century, saw in the work of the engineers of his time the pursuit of both utility and beauty. He also understood that the process of creating structures results in a series of fleeting scenes, each with a beauty and vitality that is best captured on the construction site. He called his efforts to capture these scenes "The Wonder of Work," and those efforts took him to the sites of some of the most spectacular projects in what some call "The Golden Age of American Engineering." Pennell traveled to Panama in 1912 to create images of the Panama Canal under construction—the greatest engineering work of his time. The 28 lithographs he produced there are some of the greatest images ever created of a project under construction.

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
