Abstract
Marconi's first demonstration of transatlantic radio communication on 19 December 1901, from Poldhu in Cornwall, U.K., to St John's in Newfoundland, Canada, was an important landmark in our subject. However, it was evident that the propagation path was far from line-of-sight, and the exact propagation mechanism was unclear. In an entry in the Encyclopaedia Britannica in 1902, Oliver Heaviside postulated the existence of a conducting layer in the atmosphere that would reflect radio waves and allow long-range propagation, and Robert Watson Watt proposed the name “ionosphere” in 1926.

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
