Abstract
Sibilant harmony in Nkore-Kiga is an interesting problem case for agreement-based theories of harmony, particularly Agreement by Correspondence. Previous work reports that anteriority agreement is controlled by the rightmost sibilant in the stem, and also that the quality of a sibilant is allophonically determined by the following vowel. In such a system, it is impossible for surface-oriented agreement constraints to derive strictly right-to-left harmony. However, we show that Nkore-Kiga does not work in quite this way: sibilants are conditioned not allophonically, but by morphology. This allows the facts of this case to be explained within existing Agreement by Correspondence proposals.

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
