Abstract
Abstract In a two‐level factorial experiment, the authors consider designs with partial duplication which permit estimation of the constant term, all main effects and some specified two‐factor interactions, assuming that the other effects are negligible. They construct parallel‐flats designs with two identical parallel flats that meet prior specifications; they also consider classes of 3‐flat and 4‐flat designs. They show that the designs obtained can have a very simple covariance structure and high D‐efficiency. They give an algorithm from which they generate a series of practical designs with run sizes 12, 16, 24, and 32.

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
