Abstract
We developed two models to predict volume loss due to western gall rust (Endocronartium harknessii (J.P. Moore) Y. Hiratsuka) and comandra blister rust (Cronartium comandrae Peck) on juvenile lodgepole pine (Pinus contorta Dougl. ex Loud.) dominated stands in central British Columbia. The models suggest that volume loss is significantly and positively correlated to the incidence of comandra blister rust. The relationship between volume loss and western gall rust incidence was weak. The addition of stand density data improved the statistical fit of the model. We used the growth and yield model Tree and stand simulator (TASS) to predict volume at culmination age (age at which the merchantable mean annual increment was maximized) in thirty 1-ha stem-mapped stands. The lodgepole pine trees we stem mapped were also assessed for hard pine stem rust incidence. We developed our volume loss functions assuming that trees with stem infections of both comandra blister rust and western gall rust were lethal, and that infected trees would die from ages 21 to 40. In areas where comandra blister rust is common, the losses due to the disease can be considerable. We predict that the volume losses due to hard pine stem rusts in lodgepole pine dominated stands are as high as 7.2% by culmination age.

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
