Abstract
1. Assay methods were developed for key components of the tissue factor pathway of blood coagulation, namely Factor V, Factor VII and Factor X. Using these assays, plasma from healthy laying hens, cockerels and broilers was shown to contain functional and equivalent amounts of each of these clotting factors. 2. The plasma activities for Factor V, Factor VII and Factor X can only be accurately determined when chicken tissue factor is used to initiate the coagulation mechanism in poultry plasma. Neither human tissue factor nor rabbit tissue factor forms a fully functional enzyme reactive complex with chicken Factor VII. 3. The overall tissue factor pathway coagulation mechanism was evaluated in plasma from laying hens, cockerels and broilers using the one-stage prothrombin time assay. As long as sufficient tissue factor was used, the overall clotting time results obtained with human recombinant tissue factor were not significantly different from those obtained with chicken tissue factor. 4. We conclude that poultry plasma does possess a fully functional tissue factor coagulation mechanism, but homologous chicken tissue factor must be used for in vitro assays of the components of this pathway.

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
