Abstract
189 A54-year-old-woman with well-controlled mild intermittent asthma presented with a persistent cough productive of purulent sputum. She had no symptoms of dysphagia or gastroesophageal reflux disease. She had a remote 5-pack-year smoking history and previously lived in Lake of the Woods, Ontario, where her and her husband owned and operated a tree planting company for many years. There were no risk factors for tuberculosis nor travel out of country. Computed tomography of the chest (Figure 1A) revealed an obstructing calcified lesion within the anterior segment of the right upper lobe and calcified lymphadenopathy present in the right paratracheal region. Additional calcified granulomas were noted within the right middle and lower lobes. Flexible bronchoscopy confirmed the presence of an obstructing lesion within the anterior segment of the right upper lobe (Figure 1B). Attempts were made to extract the lesion via flexible bronchoscopy, but because these were unsuccessful, a rigid bronchoscopy was performed to remove the lesion (Figure 1C). Pathological examination was consistent with a broncholith, hypothesized to be related to blastomycosis infection given her occupation and residence in an endemic area, although cultures and fungal serology were negative.

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.
