Abstract
The attitude guidance and control problem of rotating in synchronization two rigid bodies from their current attitude to their desired attitude is addressed, where the instantaneous axis of rotation must be aligned as closely as possible with an externally defined desired axis of rotation that is fixed in the inertial frame. The approach presented in this paper is based on the fact that the angular rate vector is collinear with the axis of rotation. Therefore, by controlling the direction of the angular rate, the axis of rotation is also controlled. A sliding mode control strategy is designed to minimize the quaternion error while at the same time to track a reference angular rate direction defined by the commanded fixed axis. Simulation results are provided to demonstrate the performance of the proposed guidance and control approach in a realistic scenario that considers parameter uncertainties, measurement noises, and actuation limits.

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
