Parsing Fluted Point Technological Variability in the South-Central Ice-Free Corridor
Bibliographic record
Abstract
Southern portions of the Ice-Free Corridor likely became habitable not long after 14,000 cal yr BP, available to both stemmed and fluted projectile point makers. There has been little exploration of the technological pathways through which Corridor fluted points were manufactured and maintained, nor has much thought been devoted to fluted point findspots and their implications for discarded fluted point forms. Recent findings from the Brazeau Reservoir in west central Alberta encouraged more detailed investigation of both factors. End-struck, early stage bifacial preforms and fluted late stage bifacial preforms were employed in some Corridor instances. Fluted point life histories have a determinative affect upon tool form but often leave basal morphologies isomorphic with classic Clovis forms such as those from the Naco mammoth kill. Parsing of these technological processes will help chart northward movement of the fluting concept in the Corridor toward its final, Younger Dryas expression in eastern Beringia.

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.
