Abstract
We present complete simplicial fan realizations of any spherical subword complex of type $$A_n$$ for $$n\le 3$$ . This provides complete simplicial fan realizations of simplicial multi-associahedra $$\varDelta _{2k+4,k}$$ , whose facets are in correspondence with $$k$$ -triangulations of a convex $$(2k+4)$$ -gon. This solves the first open case of the problem of finding fan realizations where polytopality is not known. We also present fan realizations of two previously unknown cases of subword complexes of type $$A_4$$ , namely the multi-associahedra $$\varDelta _{9,2}$$ and $$\varDelta _{11,3}$$ .

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
