Abstract
A52-year-old woman was referred for evaluation of apersistent dry cough and episodic hemoptysis ofabout 20 years ’ duration. These symptoms were thought to be caused by chronic laryngopharyngitis and had been treated with various antitussive agents. Her medical history was otherwise unremarkable, and physical examina-tion showed no abnormalities. Serial chest radiographs over the years had been normal. Multidetector computed tomography (CT) of the chest showed multiple calcified nodules protruding from the anterolateral wall of the trachea and sparing of the posterior tracheal membrane (Figures 1A and 1B). These projecting spicules involved the whole length of the trachea and did not obstruct the lumen (Figure 1B). Three-dimensional volume-rendered imaging, functioning as virtual bronchoscopy (Fig-ure 1C), delineated the distinct nodular mucosa of the antero-lateral tracheal wall and its extent. These findings were
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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; the direct Gemma label and the distilled Codex classifier agree on what is shown here.
