Abstract
A 1 km (~3,300 lf) long section of the North York Stormwater Trunk Sewer (STS), a 3,000 mm (118”) diameter corrugated metal pipe that services approximately 800 ha in Toronto, Ontario, has sections that are in poor condition to near failure and needs timely repairs. The culvert was built along an existing tributary to Black Creek, which resulted in a highly irregular alignment, that includes frequent sharp vertical bends and horizontal sweeps. Additionally, the culvert was constructed in several phases over a period of approximately 20 years as a result consists of multi-plate and CMP products lined with various products (tar, shotcrete, and concrete). This paper will summarize the design phase of the project to rehabilitate the deteriorating sewer, which included selecting the optimal rehabilitation methods, and producing designs and implementation plans to suit the site conditions and pipe geometry.

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
