Abstract
The Drake Silver Maps are 68-mm-diameter silver disks with maps of the sixteenth-century known world featuring Drake’s route of circumnavigation. They were probably stamped with dies. The nine existing medallions have weights from 260 to 424 grains (the heaviest one weighs about 28 g). Each of these medallions has a diameter that is about the same as that of a tennis ball. The lightest one is as thin as a thumbnail, and the heaviest one is as thick as a credit card. This article shows that they were most likely created in 1588–89: the strongest evidence for this is that they used the double-hemisphere equatorial stereographic map projection that was first used by Rumold Mercator in 1587.

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
