Abstract
One of the basic unresolved issues regarding plate tectonics is the degree of coupling between surface plates and convecting mantle below. Are the plates effectively decoupled from the mantle flow field by a low viscosity asthenosphere, or are they strongly coupled to mantle flow? While these two views are essentially incompatible, they both do a reasonably good job of predicting the motions of the surface plates, and cannot therefore be distinguished on this basis. The significant distinguishing feature for these models is the magnitude of basal shear stress that is applied to the base of the plate. While it is difficult to measure this stress directly, it is possible, in principle, to measure the corresponding deformation of the plate through observations of seismic anisotropy and to infer stress. Here we focus on the Canadian Shield, for which we expect strong plate‐mantle interaction. We show that seismic anisotropy can be used to constrain the magnitude of the stress level applied to the base of the plate, and to document the level of interaction between tectonic plates and the mantle below.

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 itClassification
machine, unvalidatedMachine predicted; both teacher heads agree on what is shown here.
