Abstract
A number of consonant shifts in the history of Athabaskan languages are considered. The goal is to better explain examples of ‘auditorily based substitution’ by invoking ‘phonetic features’ as is required by the sound change theory of Blevins (2004). We argue that the shifts are better understood as instances of Blevins’s change process involving the phonetic features ⟦grave⟧ and ⟦flat⟧. These features are defined acoustically in accord with recent phonetic studies of obstruents. It is crucial that these and other phonetic features are scalar-valued, and thus are part of a phonetics-phonology interface component which is separate from the distinctive phonological feature system.

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
