Abstract
Software maintenance teams are often faced with the challenge of adapting a system's architecture in response to problem reports as well as new functional requirements. More often than not, these maintenance objectives can be accomplished either through the addition of alternative, "patching" components, or by refactoring the original architecture. The latter approach usually results in a simpler, more cohesive design that is more robust, easier to maintain, and therefore should be preferred. This paper presents a case study describing how the Space Station Operations Control Software (OCS) team has handled architectural change after the initial delivery of the system. In particular, the paper analyses two specific examples: the reaction of the maintenance team to a design problem discovered during testing, and the incorporation of a major new feature into the software design.

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
