Abstract
ABSTRACT Let denote a finite, connected graph with vertex set . Fix and let denote the eccentricity of . For mutually distinct scalars define a diagonal matrix as follows: for we let , where denotes the shortest path length distance function of . We say that is a dual adjacency matrix candidate of with respect to if the adjacency matrix of and satisfy for some scalars . Assume now that is uniform with respect to in the sense of Terwilliger [Coding theory and design theory, Part I, IMA Vol. Math. Appl., 20 , 193–212 (1990)]. In this paper, we give sufficient conditions on the uniform structure of , such that admits a dual adjacency matrix candidate with respect to . As an application of our results, we show that the full bipartite graphs of dual polar graphs are ‐polynomial.

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
