Abstract
In this paper we explore the connection between certain answers and view-based rewritings for local regular path queries (RPQs) which are regular expressions matching paths in graph-structured data starting from a specific node. We show that differently from the case of global RPQs, which match paths starting from any node, the notions of certain answer and rewriting-based answer coincide for local RPQs. The importance of this result is that obtaining the certain answer for local RPQs can be done in polynomial time in the size of the data. We also present an automata-theoretic algorithm for computing maximal view-based rewritings. Notably, these rewritings are an exponential order of magnitude smaller than their counterparts for global RPQs.

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
