Abstract
A number of activities involved in testing software are known to be difficult and time consuming. Among them is the isolation of faults once failures have been detected. In this paper, we investigate how the instrumentation of contracts could address this issue. Contracts are known to be a useful technique to specify the precondition and postcondition of operations and class invariants, thus making the definition of object-oriented analysis or design elements more precise. Our aim in this paper is to reuse and instrument contracts to ease testing. A thorough case study is run where we define contracts, instrument them using a commercial tool, and assess the benefits and limitations of doing so to support the isolation of faults. We then draw practical conclusions regarding the applicability of the approach and its limitations.

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
