Abstract
In the pre-antibiotic era, infections were usually more frequent and serious than today. Robin Fåhraeus (1888-1958) examined the erythrocyte sedimentation rate (ESR) test for infections, which was normally carried out _in vitro _with freshly drawn blood. His extensive studies on the mechanism and physiological significance of the enhanced sedimentation of erythrocyte aggregates (rouleaux) in disease included _in vivo _simulation. This led him to propose an explanation for the finding of long white strips (“fibrin coagula”) within the blood vessels of those who had died from infections. The surge of serious infections in pandemic times has likely kindled a reemergence. He further speculated both that the weak aggregation of red blood cells (RBCs) followed the liberation of water molecules from their surfaces, and that the importance of their aggregation, which was induced by changes in serum proteins (not necessarily antibodies), extended beyond the clinic. In modern times these changes have led to immunologically significant entropic interpretations of infection-associated aggregations, whether cellular (e.g., RBC) or molecular (i.e., macromolecular polymerizations). Thus, rouleaux formation displays a process at the cellular level that can proceed in parallel at a less visible macromolecular level. It has been proposed that, when intracellular, aggregations would discriminate between self and not-self proteins in the crowded cytosol. Favoured by an associated pyrexia, this could lead, by mechanisms to be determined, to the preferential loading of peptides from proteins deemed foreign for presentation as MHC complexes to specific clones of immune cells.

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
