Abstract
Planar partial 3-trees are subgraphs of those planar graphs obtained by repeatedly inserting a vertex of degree 3 into a face. In this paper, we show that planar partial 3-trees have 1-string B1-VPG representations, i.e., representations where every vertex is represented by an orthogonal curve with at most one bend, every two curves intersect at most once, and intersections of curves correspond to edges in the graph. We also show that some subclasses of planar partial 3-trees have {L}representations, i.e., a B1-VPG representation where every curve has the shape of an L.

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
