Abstract
Granites form when silica‐rich magma intrudes into the crust and slowly crystallizes. Such intrusions are discontinuous in space and episodic in time, resulting in a mosaic of ages for granites from a given region. Although the episodicity of granitoid ages is well known [ Condie , 1998; Kemp et al. , 2006], how representative samples are of age distributions in the preserved continental crust is unclear. This is because sampling strategies are generally dictated by mineral exploration, accessibility of outcrops, or availability of geologic maps, none of which necessarily leads to an unbiased representation of age distributions in the continental crust. For instance, large age peaks at 2.7 and 1.9 billion years ago in the Canadian and Baltic shields may reflect extensive sampling of these shields [ Condie et al. , 2009a].

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
