A MULTISCALAR APPROACH TO MIGRATION AND SOCIAL CHANGE AT MIDDLE POSTCLASSIC XALTOCAN
Bibliographic record
Abstract
Abstract Ethnohistoric documents characterize the thirteenth and fourteenth centuries in central Mexico as an era of endemic warfare and mass migration, processes that archaeologists have causally related to the development of the Aztec Empire. In this paper, we explore a striking transition in this dynamic, but poorly understood period at the Otomi capital of Xaltocan. The archaeological record reveals that with the adoption of Aztec II Black-on-Orange pottery bya.d.1240, Xaltocan witnessed the expansion of the island to accommodate more residents, construction of thechinampaagricultural system, and the emergence of two subpopulations with distinct household organization, consumption, and funerary practices. We link a microscale examination of domestic activities with contextual understanding of macrolevel population dynamics, ethnic politics, and political-economic processes, and argue that this shift is due to an influx of migrants. These findings have significant implications for shifting conceptions of identity associated with the emergence of large polities.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
