Abstract

fetched live from OpenAlex

Abstract Let be a regular semilocal ring of dimension which contains , the number of maximal ideals of which are assumed to be all of the same height, and the punctured spectrum of , that is, without the maximal ideals. We show that the Witt ring of has non‐trivial generators as ‐algebra, which satisfy for all . If is integral, then these generators become trivial over the fraction field of . In particular, the natural morphism is not injective.

Full frame distilled prediction

Teacher imitation

Not 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.
