Abstract
Abstract This paper addresses the recent debate surrounding claims about the presence of a small Aurignacian assemblage interstratified between Châtelperronian deposits at the site of Grotte des Fées de Châtelperron. We review the current debate and provide an assessment of the various studies that have been published in its context. As a way to evaluate whether the original claims stand irrespective of potential taphonomic disturbances at the site, we undertake a comparison of the frequency of putative ‘Aurignacian diagnostics’ in this and nineteen other Châtelperronian assemblages from south-western France. No matter how these diagnostics are defined, this analysis demonstrates that such implements are not abnormally more abundant at Châtelperronian assemblages, even when considered solely for Level B4, which is said to document the debated interstratification. We propose alternative explanations for the presence of such curated tools made of exotic lithic raw materials in the context of the assemblage from Grotte des Fées that are more concordant with what is known about the impact of sample size on typological richness and about the mobility patterns of Paleolithic hunter-gatherers, and conclude with some thoughts about the significance of interstratification in Paleolithic deposits.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
