LATE DORSET TRIANGULAR MIDPASSAGES IN THE CANADIAN ARCTIC AND NORTHWEST GREENLAND: ORIGINS AND DISPERSAL
Bibliographic record
Abstract
Midpassages are the most recognizable architectural feature associated with the entire Paleoeskimo period (2800 BC–AD 1300) in the Canadian and Greenlandic Arctic. Usually built of stone, midpassages are rectangular-shaped axial structures that run through the center of tent rings and semisubterranean house depressions. However, a unique triangular form of midpassage developed in association with the Late Dorset complex in the Boothia Peninsula area of the Canadian Arctic around AD 400. Unlike the rectangular-shaped varieties that were built contemporaneously across the Arctic, distribution of the triangular form is limited, and occurrences are rare. Initially, construction appears restricted to the Boothia Peninsula region, where the form persisted for the subsequent 400 years. After AD 900, they are found in Inglefield Land, Greenland, and a few other locations in the Canadian Arctic where they continued to be built until around AD 1200, representing an over 800-year period in a remarkably unvarying configuration. Further, these triangular midpassage structures very likely represent a regional architectural variant that moved northward with the Late Dorset diaspora after AD 800.

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.
