Vredefort, Sudbury, Chicxulub: Three of a Kind?
Why is this work in the frame?
A frame that forgets how it found something cannot be audited. These are the routes that admitted this work.
Full frame distilled prediction
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)
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
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.

Abstract
Vredefort, Sudbury, and Chicxulub are the largest known terrestrial impact structures. All have been cited as multi-ring basins. The available data indicate that all have some form of multiple-ring attributes, most commonly structural features. Chicxulub, however, is the only example with morphological ring features. There are also commonalities in the structural and lithological features of Vredefort and Sudbury, and it is possible to construct a generalized compilation of the character of 200–300 km diameter impact basins on Earth. It is not clear, however, that any of these structures had the original morphological characteristics of large lunar multi-ring basins. Additional data and synthesis are required to fully characterize these structures in order to realize their potential to constrain large-scale cratering processes. If this is not sufficient incentive for further studies (the environmental effects of Chicxulub aside), the Vredefort, Sudbury, and Chicxulub impact events are also the reason for the existence of world-class mineral and hydrocarbon deposits.
