Abstract
A comparison is made between two models, one assumed to be two-degree-of-freedom (2-DOF) and the other 3-DOF. To study the dynamic behavior of the two models, transfer functions of the system are used, and root-loci plots are found to be extremely valuable for arriving at some important insights. A dimensionless number, designated as the roll number, is identified, with the property that for a system whose roll number is small, the 3-DOF model is effectively reduced to a 2-DOF model as a result of pole-zero cancellation. This number can be used to great advantage in the structural design of the vehicle. As the forward speed of the vehicle exceeds a certain limit, it is found that the response may become oscillatory, so the speed should be kept within a range to get satisfactory results.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

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
