Abstract
Root disease in 50-70 year-old fully stocked white spruce stands in central British Columbia was investigated in two fashions. The first method was done by root excavation; to establish the identity of the causal organism, to investigate the etiology, and assess the damage caused by the disease. The second method involved, a survey of six 1.2 ha stands in order to estimate the incidence of the disease. Polyporus tomentosus Fr. was the only pathogen involved. Infection of spruce trees resulted when roots contacted previously existing inoculum. Although tree species other than spruce were in contact with infected roots, only spruce was infected by the root rot. No consistent crown symptoms were apparent. A complex with the root weevil Hylobius warreni Wood was evident. Results from the survey estimated that 28.4% of the area investigated was occupied by diseased trees. Of these 22.6% had butt rot, and for whole stands, 1% of the standing trees were windthrown in one season as a result of disease. Diseased trees suffered a 20% reduction of basal area increment. It was not possible to measure the mortality caused by the fungus.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
