Abstract
Debugging is known to be a notoriously painstaking and time-consuming task. As one major family of automated debugging, statistical debugging approaches have been well investigated over the past decade, which collect failing and passing executions and apply statistical techniques to identify discriminative elements as potential bug causes. Most of the existing approaches instrument the entire program to produce execution profiles for debugging, thus incurring hefty instrumentation and analysis cost. However, as in fact a major part of the program code is error-free, full-scale program instrumentation is wasteful and unnecessary. This article presents a systematic abstraction refinement-based pruning technique for statistical debugging. Our technique only needs to instrument and analyze the code partially. While guided by a mathematically rigorous analysis, our technique is guaranteed to produce the same debugging results as an exhaustive analysis in deterministic settings. With the help of the effective and safe pruning, our technique greatly saves the cost of failure diagnosis without sacrificing any debugging capability. We apply this technique to two different statistical debugging scenarios: in-house and production-run statistical debugging. The comprehensive evaluations validate that our technique can significantly improve the efficiency of statistical debugging in both scenarios, while without jeopardizing the debugging capability.

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
