Abstract
A novel complementary clamp piezoworm stage was developed to be integrated into a two-axis configuration for tracking profiles in different size regimes. It is based on novel clamp designs that permit complementary action using the same flexure frame in a compact arrangement. A novel direct connection to a commercial slide was used to eliminate backlash and the need for high-precision alignment of a rod and slide. A model was developed and used to design the controller structure and choose thresholds for smooth operation. Complete assessment of the closed-loop performance of a single-axis and dual-axis stage in different regimes was done. The average positioning accuracy of the stage was plusmn20 nm. For tracking applications, the average error of the two-axis stage was 8 nm in the nanometer regime, 1.72 mum in the micrometer regime, and 1.85 mum in the millimeter regime.

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
