Abstract
This study addresses the political and military structure of early Teotihuacan through the analysis of oxygen-isotope ratios in skeletal phosphate from 41 victims of a sacrifice associated with the Feathered Serpent Pyramid. Oxygen-isotope ratios are markers of geographic identity. A comparison of bone and enamel values, which provides a contrast between environments experienced during growth and those of adulthood, illustrates that at least four different regions are represented in this sample. Those identified as soldiers had either lived locally since childhood or had moved to Teotihuacan from several foreign locations. Most had lived in Teotihuacan for a prolonged period before their death. This pattern suggests foreign “recruitment” or mercenary behavior. The women had either lived all their lives in Teotihuacan or had moved from there to a foreign location. Most of the individuals in the center of the pyramid (burial 14) did not come from Teotihuacan, nor had they lived in the city long before their deaths. We suggest that the choice of victims was meant to demonstrate Teotihuacan's powerful ideology to the rest of the Mesoamerican world. Notably, this isotopic evidence of physical interaction between Teotihuacan and foreign regions considerably predates the currently existing archaeological evidence.

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
