Abstract
Cylindrical hubs with fan blades are inserted into a pipe inside a modified camera box—a recently introduced structure intended to host differently-shaped ducts behind an aperture. The resulting structures increase the reproducibility of commonly used simplified jet-engine inlet models and are designed to serve as precisely-defined radar cross section (RCS) benchmarks with reliable reference results. The design, manufacturing, and assembly of the measured structures are detailed; the RCS measurement setup, data collection, and post processing are documented; and the uncertainty in measured RCS data is quantified with the help of simulations. Results show that the fields scattered by the structures, while highly sensitive to geometric and material perturbations, can be both measured and simulated accurately even at frequencies with many propagating modes inside the pipe.

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
