From chipped to ground: the spatio-temporal systematics of 9,000 years of archaeological change in southwest British Columbia
Bibliographic record
Abstract
Au cours des 9000 dernières années de la préhistoire sur la côte sud-ouest de la Colombie-Britannique il y a eu une transition technologique des assemblages composés principalement d'outils de pierre taillée vers des assemblages composés de pierre polie, d'os et d'andouiller. Les explications courantes de cette transition se fondent sur relativement peu d'assemblages et un concept de phases chronologiques profondément enraciné. Dans cette étude, je combine les données produite par les firmes archéologiques, connus sous le nom de littérature « grise », avec des sources académiques et des rapports provinciaux archivés, pour évaluer la nature de la transition et déterminer si le concept de phase influence l'interprétation du changement archéologique. Les conceptions actuelles d'une transition uniforme et progressive d'assemblages dominés par la pierre taillée vers les assemblages dominés par la pierre polie sont inexactes. Elles accentuent les contraintes interprétatives sur l'analyse du changement archéologique et elles démontrent la nécessité de conceptualiser l'espace et la chronologie comme variables continues plutôt que comme unités.

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.
