Abstract
Polygon search is the problem of finding mobile intruders who move unpredictably in a polygonal region. In this paper, we consider a special case of this problem, called boundary search, where the searcher is allowed to move only along the boundary of the polygon. We concentrate on a single searcher with one flashlight (called a 1-searcher), but it is known that a single boundary 1-searcher has the same searching power as a single boundary searcher with 360/spl deg/ vision. Our main result is that the movement of the searcher can be controlled by a finite-state machine having only seven states. This automaton has no built-in information about the input polygon and, for any given polygon P, if P can be searched by a boundary searcher at all, then this automaton will successfully search P, no matter where on the boundary of P it is initially placed. All information about P is acquired by the automaton online, as it searches P. We also show that if P can be searched by a boundary searcher, then our automaton searches it by circling its boundary less than three times.

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
