Abstract
For most of the past 5,000 years, the North American Arctic has seen distinct cultural developments in its eastern and western regions, with the boundary between them located in the Amundsen Gulf region in northwestern Canada. This boundary was traversed by two major migration episodes that define the ‘big picture’ of North American Arctic archaeology, but for much of the remainder of prehistory, there are only rare indications of communication or movement across it. In this paper, we assess the reasons for this boundary, the evidence for interaction across it, and the implications for cultural developments on both sides. In order to approach these issues, we also attempt to understand the significant gaps in the archaeological record caused by the region’s severe coastal erosion, currently accelerating due to warming climates.

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
