Abstract
WOMAN OF CARIBBEAN DEscent presented to an outside hospital with a history of several months of recurrent postprandial right upper quadrant pain associated with nausea and vomiting.Her white blood cell count and liver function test results were within normal limits.She underwent abdominal ultrasonography and a computed tomography scan of the abdomen, which showed cholelithiasis and a questionable cystic dilatation of the common bile duct.She requested a transfer to the Weill Cornell Medical Center.Serologic test results for Echinococcus were negative.A magnetic resonance cholangiopancreatography was ordered to characterize the anatomy.This showed a round lesion centered in the hepatic hilum measuring 1.9 ϫ 1.9 ϫ 2.1 cm with thin internal septations (Figure 1).Although it was in proximity to biliary structures, a direct communication was not visualized.There was no evidence of lymphadenopathy.She was scheduled for a laparoscopic cholecystectomy and resection of the lesion (Figure 2). What Is theDiagnosis? A. Mirizzi syndrome B. Carcinoma of the gallbladder C. Cystadenoma of the cystic duct D.

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.
