Abstract
This paper describes the experimental characterization of the yaw response of a range of generic tail fin shapes: delta wings, right triangles, rectangles, and ellipses. The fins were tested in a wind tunnel without the complication of blades and nacelle. They were released from an initial angle, usually 45°, and the subsequent response recorded using an accurate potentiometer. Unsteady tail fin performance can be analysed using unsteady slender body theory and the quasi-steady analysis originally developed for wind vanes. Both predict a linear, second order response so the measured responses are quantified in terms of the natural frequency and damping ratio. It is shown that unsteady slender body theory is slightly more accurate, but both fail to describe the full complexity of the response.

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
