Abstract
A 20-month-old castrated male Labrador Retriever with a 3-month history of anorexia, weight loss, and vomiting was evaluated. Plasma biochemical abnormalities included marked hyperglobulinemia and hypercalcemia. Serum levels of parathyroid hormone, parathyroid hormone-related protein, 25-hydroxyvitamin D, and 1,25-dihydroxyvitamin D were either low or within reference intervals. Gastric wall thickening and abdominal lymphadenomegaly were observed with abdominal ultrasonography. Cytologic evaluation of a sample obtained via fine-needle aspiration of the gastric wall revealed pyogranulomatous inflammation and numerous poorly stained hyphae. Partial gastrectomy was performed, and a diagnosis of gastric pythiosis was made by immunohistochemical staining of infected gastric tissue, as well as by immunoblot serology. This case demonstrates that diagnostic samples for cytologic evaluation can be obtained by fine-needle aspiration of Pythium insidiosum-infected tissues and that a presumptive diagnosis can be made by examination of a Romanowsky-stained smear. Furthermore, pythiosis should be considered as a differential diagnosis for hypercalcemia, especially in young dogs with inflammatory lesions that have a granulomatous component. The mechanism for the hypercalcemia in this dog was not determined; however, calcium concentrations normalized after surgical resection of the gastric lesion.

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
