New constraints on Laurentide postglacial rebound from absolute gravity measurements
Why this work is in the frame

Abstract
Repeated absolute gravity measurements have been made over a period of several years at six sites along a 3000 km‐long, mid‐continental, North American profile from the coast of Hudson Bay southward to Iowa. With the exception of the southern‐most site, the observed rates of change of gravity are significantly higher than rates predicted by current models, such as ICE‐3G and a laterally homogeneous, standard Earth. The observed gravity change rates suggest significant modifications, such as a 2 to 3‐fold increase in lower mantle viscosity or a 50% increase in Laurentide ice sheet thickness west of Lake Superior.

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
