Abstract
PhelLinus uenii (Mtrr.\Cilb., csuse of laninated root rot, infects nearly all conmercially important conifer species in ihe weslern United States and Canada.Infection in a young stand occurs when developing roots of young trees contact residual infested roots and stunps fron a preceding stand.Although soil fumigants applied to infested slunps sill reduce the amount of inoculum, the chemicals are highly roxic and require special handling.We are interested in de'eloping stump teatmnts that are safe and environnenrall) acceprable.Because La,rricidin, a fungicide, has been demonstrated both to inhibit P aetrii and to be oflow nammalian toxicity, it was tested as a candidate control agent.Two concentrations of Lauricidin in a carrier solu' tion o{ dimethyl sulfoxide (DMSO)and ethylenedisminetetraacetic acid (EDTA), and the carier solurion alone, were applied to holes drilled in the tops of Douglas'fir (Psearlotsrgd rrenzi"It0 stunps infested by P aet.t:Half ofihe srumps {re evaluated a{rer 4 nonths and the rest after 32 monrhs.Lauricidin did not appear to nove significandy in lhe stumps or rooG.Any effect of lhe treetmenrs on survival ofP aeirji occurred near the treaiment application holes and appeared to be caused by the carrier solution.We concluded thal lhe formulalion ofLauricidin tested in this srudy is relatirely imnobile in wood and for that reason a poor choice as a chemical for treating stumps ro control P. u)eitii.

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
