Abstract
Oregonscape Crossing the Columbia River has long been a major undertaking. During much of the nineteenth century, ferries and boats provided the only means of moving from one side of the river to the other. In the 1890s, railroad bridges began to allow trains to move between Oregon and Washington, and in 1917, the Interstate Bridge opened, connecting Portland with Vancouver, Washington. A few years later, work began on another river crossing, this time at Cascade Locks. The impressive Bridge of the Gods opened in 1926, allowing wagons, trucks, and cars to pass ninety feet above river traffic. In September of the following year, aviator Charles Lindbergh flew along the river on his way to Portland as part of a cross-country tour celebrating his famous Atlantic flight. He circled over the bridge and flew underneath the central span before continuing on to the airport at Swan Island. Unfortunately for history, he decided to do the stunt on the spur of the moment, and no cameras were on hand to record the event. When the Bonneville Dam was built in the 1930s, the Columbia River began to change from the wild river Lewis and Clark saw to the navigable stream it is today. The water that backed up behind the dam widened the river, and in 1940, the Bridge of the Gods was raised 50 feet and lengthened by over 700 feet to accommodate the changed river. That project took about three months, and this photograph documents the process about ten days before the bridge reopened. — Mikki Tint, former special collections librarian, OHS Research Library Learn more about the Bridge of the Gods at www.ohs.org/research/quarterly/oregonscape.cfm. ...

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
