Abstract
An almost complete arrow found in British Columbia in the early 20 th century has been re-discovered in the Royal BC Museum collections. Speculation as to its anti- quity was tested by radiocarbon dating, which reveals that the artifact was likely made in the middle of the second millennium AD. The arrow was compared to recent finds of both arrows and darts from glaciers and ice pat- ches. The failure of this specimen to clearly fit the criteria of either of these weapon tech- nologies raises some new questions. Resume. Une fleche presque complete trou- vee en Colombie-Britannique au debut du 20ieme siecle a ete redecouverte dans les col- lections du Royal British Columbia Museum. Les speculations relatives a son antiquite ont ete verifiees par la datation au radiocarbone qui indique que l'objet a ete realise proba- blement au milieu du deuxieme millenaire de notre ere. La fleche a ete comparee aux decouvertes recentes de fleches et pointes de dard provenant de glaciers. Le specimen du musee ne concorde pas de facon claire avec les criteres des autres technologies des projectiles analyses et souleve de nouvelles questions.

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.
