Abstract
This paper proposes a new path planning algorithm for robotics called Informed SRRT <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">*</sup> . Compared to conventional RRT <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">*</sup> algorithms with Euclidean metrics, our algorithm extends the approach by incorporating a local planner from SRRT to satisfy both external and internal constraints. To compute the path to the goal region, we use parameterized cubic curves instead of computationally expensive numerical methods. We add two extra lines at the endpoints of the Bézier spline to leave rooms for the rewiring process. Kinematic constraints require at least three state connections to be tweaked during rewiring. The algorithm always ensures that the path has G <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> continuity of curvature within upper-bound constraints. Simulation results demonstrate that the proposed method finds shorter paths than SRRT while maintaining the same iteration of node sampling.

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
