Abstract
Rocks in the Late Ordovician paleotropics commonly exhibit the now well-known, positive Hirnantian \nIsotopic Carbon Excursion (HICE). This event is coincident with both continental scale glaciation in \nGondwana and dramatic extinction across the marine realm (Delabroye and Vecoli, 2010). Both the \nproximate cause of the isotopic excursion and the ultimate drivers of large scale cooling remain the subject \nof debate. Suggestions range from tectonic effects on weathering or changes in biological productivity, \nthrough large basaltic eruptions to gamma ray bombardment. Discussion of these alternative models is \nbeyond the scope of this short paper, however. Our intent is to briefly report the direct association of a new \nhigh resolution δ13Corganic record from rocks at a high latitude site that also bears biostratigraphic and \nsequence stratigraphic data needed to link Hirnantian oceanographic changes (especially those recorded \nin the paleotropics) with glacial events in the peri-Gondwanan realm (Delabroye and Vecoli, 2010; Young \net al., 2010).

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
