Why this work is in the frame

A frame that forgets how it found something cannot be audited. These are the routes that admitted this work.

affAt least one author lists a Canadian institution in the pinned OpenAlex snapshot.

Abstract

fetched live from OpenAlex

Hydridlieferant: Frustrierte Lewis-Paare aus tBu3P und Al(C6F5)3 aktivieren H2 unter Bildung von [tBu3PH][(μ-H)(Al(C6F5)3)2], das mit nichtaktivierten Olefinen zu RAl(C6F5)2 (R=Et oder Cy) und [tBu3PH][Al(C6F5)4] reagiert. Der vorgeschlagene Reaktionsmechanismus umfasst eine Olefinaktivierung durch Aluminium, was durch die Isolierung des Cyclohexen-Komplexes [Al(C6F5)3⋅(C6H10)] gestützt wird.

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.
