Abstract
Summary The pathogenic fungus, Ciboria batschiana infects acorns prior to fall collection and if they are not freed of the fungus by thermotherapy seedlots can suffer serious losses during subsequent storage. However, since thermotherapy is time‐consuming and expensive, and sometimes has undesirable side‐effects, its use is not justified without knowing if and how intensively a seedlot is infected. It is demonstrated here that typical lesions on the surface of the cotyledons are a reliable indicator of infection by C. batschiana and that a method based on mycelium development on incubated cotyledons allows C. batschiana infection levels to be determined within 1–2 weeks. There were no significant differences in estimated C. batschiana infection levels between the visual assessment of the lesions before the incubation and the visual assessment of outgrowing mycelium from these lesions after the incubation. Using one or both of the described methods a decision can be made on the necessity for thermotherapy of acorn seedlots, i.e. before nursery sowing or long‐term, cold storage. The test based on mycelium development on incubated cotyledons can also be used for quality control following thermotherapy.

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
