Abstract
Fluting or basal thinning of lanceolate points can be readily recognized, so that much reasoning about the initial occupation of the Ice-Free Corridor has centered on the fluted point phenomenon.Fewer comparisons have been made with stemmed points from the Plateau and Great Basin, which have considerable morphological variability and a time range that extends from 14,000 or more years ago to as recently as ∼8000 years ago.A broad time range is also true for Alaskan stemmed points.Yet, a variety of stemmed point morphologies became quite common in Alberta, as the entire Ice-Free Corridor deglaciated and became biotically habitable no later than 13,200 years ago.Like the northern Great Plains, both regions also had access to the expanding Corridor.The relative abundance of both fluted and stemmed points in the Corridor has significant implications for our understanding of rapidly evolving genetic inferences about early PaleoIndigenous populations as deglaciation proceeded.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
