Abstract
Dieulafoy lesion is a rare cause of massive GI bleeding. It’s an abnormal sub-mucosal artery protruding from a minute mucosal defect (≤3 mm). A 31 yearold male presented with complaints of hematochezia. Preliminary investigations failed to locate the exact source of bleed. Enteroscopy suggested distal ileal bleed. At laparotomy, an ulcerated nodular lesion, approximately 0.5 cm was identified in distal ileum. 30 cm of ileum along with mesentery was resected. Histology revealed it to be Dieulafoy lesion. Dieulafoy lesion is uncommon but one of the causes of obscure gastrointestinal bleeding that could result in treacherous and life-threatening gastrointestinal haemorrhage. This lesion is difficult to identify and high index of suspicion is required to make diagnosis. Hence, it should be considered in the differential diagnosis of active GI bleeding. The definitive diagnosis is based only on histopathology.

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.
