Abstract
An 18-month-old Oldenbourg filly was presented with a bleeding diathesis. Laboratory testing included platelet count, gingival bleeding time, prothrombin time (PT), activated partial thromboplastin time (aPTT), von Willebrand factor (vWf) antigen, clottable fibrinogen, clot retraction time, PFA-100 closure time, platelet aggregometry (on platelet-rich plasma), and thrombelastography (TEG). TEG was performed by using kaolin and tissue factor as coagulation activators. Expression of the platelet receptor for fibrinogen was assessed by flow cytometry by using anti CD41 (alpha(IIb) or glycoprotein IIb)/CD61 (beta(III) or glycoprotein IIIa) and anti-CD41 antibodies. Abnormal laboratory findings included prolonged oral mucosal bleeding time (>12 hours), prolonged closure time with collagen/ADP (>300 seconds), and absence of clot retraction after 60 minutes. TEG reaction times were similar with kaolin and tissue factor in the patient and a control horse. However, maximum amplitudes in the patient were decreased with both kaolin (43.7 mm; control, 63.9 mm) and tissue factor (37.7 mm; control, 57.8 mm). Platelet aggregation responses to ADP and collagen were profoundly reduced in the affected horse compared with a control. Flow cytometry showed an absence of CD41 and decreased expression of CD41/CD61-reacting antigen on the patient's platelets compared with those from a control horse. The laboratory findings supported a diagnosis of Glanzmann thrombasthenia, likely caused by a mutation in the gene encoding the GPIIb subunit.

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
