Abstract
ABSTRACT nce County, Wisconsin was the first to receive systematic study (Giese et al., 1964; Westing, 1966; Millers et al.,Sugar maple (Acer saccharum Marsh.) decline has been a problem 1989). Since then, well-documented sugar maple de-on the Allegheny Plateau for the last two decades. Previous work found that sugar maple is predisposed to decline by poor nutrition clines have occurred in Massachusetts in the 1960s and incited to decline by severe insect defoliation. Nutritional diagno- (Mader and Thompson, 1969), Ontario in the 1970s ses have been based on foliar chemistry; there is little information on (Hendershot and Jones, 1989; Gross, 1991), Quebec, soil attributes that influence susceptibility. We evaluated relationships New York, and Vermont in the 1980s (Bernier and among soil characteristics, foliar chemistry, and sugar maple decline Brazeau, 1988a,b,c; Kelley, 1988; Bernier et al., 1989; for 43 stands on the Allegheny Plateau in New York and Pennsylvania Hendershot and Jones, 1989; Bauce and Allen, 1992; using correlation and stepwise regression techniques.

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
