Why this work is in the frame
A frame that forgets how it found something cannot be audited. These are the routes that admitted this work.

Abstract
We describe a framework for randomized unit testing, and give empirical evidence that generating unit test cases randomly and then minimizing the failing test cases results in significant benefits. Randomized generation of unit test cases (sequences of method calls) has been shown to allow high coverage and to be highly effective. However, failing test cases, if found, are often very long sequences of method calls. We show that Zeller and Hildebrandt's test case minimization algorithm significantly reduces the length of these sequences. We study the resulting benefits qualitatively and quantitatively, via a case study on found open-source data structures and an experiment on lab-built data structures

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
