Abstract
Abstract A rapid and sensitive method has been developed for the specific detection of Erwinia amylovora (Burr.) Winslow et al. using the polymerase chain reaction (PCR). The method involves amplification of a 187 bp DNA fragment, probably of chromosomal origin. All 69 cultures of E. amylovora in an international collection from 10 host species in five countries were successfully identified using the primers. In contrast, discrete PCR products were not amplified from 29 other Erwinia species or from 20 other species of plant pathogenic and sapro‐phytic bacteria. A detectable 187 bp product was consistently amplified from reactions containing as few as 10 colony‐forming units in culture and plant tissue. In field trials PCR could detect E. amylovora in apple flowers before fire blight symptoms occurred. This method may have potential in pre‐symptomatic disease management.

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
