Abstract
Forest floors in single- and mixed-species stands of western hemlock (Tsuga heterophylla) and western redcedar (Thuja plicata) in the coastal forest of southern British Columbia, Canada, were examined with respect to acidity (pH), and concentrations of total C, total N, mineralizable-N, and total Ca, Mg, K, P, and S. Using four properties (pH and total C, N, and Ca), canonical discriminant analysis separated forest floors of hemlock and redcedar stands, with mixed-species stands overlapping those of each single-species stand. Despite interactions between stand type and location, several properties were significantly different or showed clear trends between stand types. Forest floor pH, and concentrations of mineralizable-N, total Ca, and total K increased, while concentrations of total C and S decreased in the order from hemlock to hemlock-redcedar to redcedar stands. These results are consistent with other studies and suggest that forest floor decomposition and nutrient availability increase with increasing presence of redcedar.

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
