Abstract
Infrastructure-as-code automates the process of configuring and setting up the environment (e.g., servers, VMs and databases) in which a software system will be tested and/or deployed, through textual specification files in a language like Puppet or Chef. Since the environment is instantiated automatically by the infrastructure languages' tools, no manual intervention is necessary apart from maintaining the infrastructure specification files. The amount of work involved with such maintenance, as well as the size and complexity of infrastructure specification files, have not yet been studied empirically. Through an empirical study of the version control system of 265 Open Stack projects, we find that infrastructure files are large and churn frequently, which could indicate a potential of introducing bugs. Furthermore, we found that the infrastructure code files are coupled tightly with the other files in a project, especially test files, which implies that testers often need to change infrastructure specifications when making changes to the test framework and tests.

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
