Abstract
Software peer review is practiced on a diverse set of software projects that have drastically different settings, cultures, incentive systems, and time pressures. In an effort to characterize and understand these differences we examine two Google-led projects, Android and Chromium OS, three Microsoft projects, Bing, Office, and MS SQL, and projects internal to AMD. We contrast our findings with data taken from traditional software inspection conducted on a Lucent project and from open source software peer review on six projects, including Apache, Linux, and KDE. Our measures of interest include the review interval, the number of developers involved in review, and proxy measures for the number of defects found during review. We find that despite differences among projects, many of the characteristics of the review process have independently converged to similar values which we think indicate general principles of code review practice. We also introduce a measure of the degree to which knowledge is shared during review. This is an aspect of review practice that has traditionally only had experiential support. Our knowledge sharing measure shows that conducting peer review increases the number of distinct files a developer knows about by 66% to 150% depending on the project. This paper is one of the first studies of contemporary review in software firms and the most diverse study of peer review to date.

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
