Abstract
This paper addresses decision-making issues faced by most water utilities regarding their water mains. An overview is provided to explain the difference between failure management of small-diameter mains in distribution systems and failure prevention in large-diameter transmission pipelines. The paper further describes past and on-going research at the National Research Council of Canada (NRC) on these issues. A description is provided for the application of fuzzy logic to assess failure risk of large diametertransmission pipelines. Case studies are described to illustrate the application of a multivariatetime-exponential model to historical failure rates in small-diameter distribution mains. The impact of time-dependent factors on water main breaks is demonstrated, with special emphasis on the effect of various cathodic protection measures on the life-cycle costs of water mains.

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
