Abstract
Many early sites throughout North America bear similarities regarding their lack of worked bifaces. Conversely, unifacially flaked tools at sites ranging from Blackwater Draw in New Mexico to Debert in Nova Scotia to Harney Flats in Florida are pervasive. It seems evident that unifaces were the hallmark of the Paleoindian period and represent stylistic homogeneity. Paleoindian peoples also shared a preference for using high-quality silicates from which they fashioned their tools. Tools of these stone types are often in sites great distances from their geologic source. Also, the idea that Paleoindians subsisted primarily by hunting now extinct megafauna is an overly simplistic view of how they utilized and adapted to their environments. Last, the Harney Flats report revisits the structural patterning at several eastern Paleoindian sites, such as Debert (Nova Scotia), Holcombe Beach (Michigan), Thunderbird (Virginia) and Vail (Maine) as a matter of comparison.

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.
