Abstract
This article reviews the historical and present prospects of ethnohistorical and ethnographic work in the South American Gran Chaco. Geographically the Chaco is a semi-arid central South American plain, some one million square kilometers in size, encompassing portions of northern Argentina, eastern Bolivia, and western Paraguay. Average rainfall oscillates around 800 mm/yr, with the peripheries being wetter and the central Chaco drier. Some 250,000 indigenous people belonging to more than twenty ethnic groups live in the Chaco. Traditional ethno-linguistic categorization classifies them into six main linguistic groups: Mataco-maká (Wichí-Mataco, Chorote, Nivaclé-Chulupí, Maká), Guaycurú (Toba, Toba-Pilagá, Pilagá, Mocoví, Mbayá-Caduveo), Lule-Vilela (Chunupí), Lengua-Maskoi (Lengua, Sanapaná, Angaité, Enenlhet), Zamuco (Chamacoco-Ishir, Ayoreo) and Tupí-Guaraní (Ava-Chiriguano, Chané, Tapiete, Isoseño-Guaraní, and Guaraní Occidental). The last group is the largest, including nearly 100,000 people, of whom the majority live in Bolivia. Unlike their Amazonian and Andean counterparts, Chaco indigenous peoples have yet to establish transnational, pan-indigenous representative bodies of their own. The present position of Chaco scholars is in many ways isomorphic to that of Chaco indigenous peoples, as Chaco anthropology has not established itself as an internationally recognized field of endeavor. Nevertheless, recent scholarship in the region is currently producing an original synthesis of many of the long-standing concerns of Andeanist and Amazonianist scholarship, respectively. A case can also be made for a new direction for research, based upon intriguing anthropological and historical parallels between the North American Great Plains and the South American Gran Chaco. The very indefinition of Chaco scholarship may also be its principal strength, and the past and present directions of Chaco research both draw upon and make a persuasive case for returning to comparative and area studies approaches in anthropology.

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
