Abstract
The water surface elevation (WSEL) of the existing Highline Canal is approximately 20 ft above the WSEL of the existing San Tan Canal (STC), where the reclaimed water from the City of Mesa would be discharged, necessitating the design and construction of a low-head gravity pipeline of varying diameters. The alignment of the gravity pipeline crosses a spur of the Union Pacific Railroad (UPRR) and Arizona State Highway 87. Near this crossing is a 350-ft segment of abandoned 24-in. C-76 concrete gravity pipeline housed in a steel casing and hydraulic modeling suggested that incorporating this abandoned pipeline into the alignment of the proposed low-head gravity pipeline was feasible. Unfortunately, the existing pipe condition is structurally inadequate. Repurpose the existing C-76 gravity pipeline and manholes with a Sprayed-in-Place pipe (SIPP) liner saved months, or years, of schedule delays, and upwards of a million dollars in permitting and construction of a new trenchless crossing.

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
