Abstract
From the Julio-Claudian era until around the third quarter of the 3rd c. A.D., the amphorae that H. Dressel referred to as the Dressel 20 type in his table of amphorae discovered at the Castra Praetoria and, to a lesser extent, at Monte Testaccio, was used to transport olive oil from Hispania Baetica to Rome and the NW provinces of the empire. The artificial mound of Testaccio, just over 40 m high and covering an area of 2.2 ha, is a huge dump composed mainly of Dr. 20 amphorae, standing near the Emporium on the left bank of the Tiber. As has been acknowledged, its abandonment, a direct consequence of the construction of the Aurelian Walls from 271 onwards, did not signal the end of olive-oil imports from Baetica . In a similar way, the end of Dr. 20 production, in c. 260-270, does not point to the end of oil-amphora production in that province and, more precisely, in the Guadalquivir basin where this form originates.

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
