Piping Network Repair Negative Case Package

Calculates source-bound piping network repair metrics from a deterministic SSC-11 task-owned source pack. The template combines baseline and variant hydraulic values, velocity and headloss deltas, bend thrust, support shift margin, negative-case capture, unresolved repair count, and an overall synthetic pass score.

with-tool: The model is given an executable Python calculator script.

Difficulty

Each template is sampled at three tiers. Harder tiers may hide inputs, forcing the model to infer them from the scenario description.

All inputs remain visible at every tier

For this template, difficulty scales through parameter and scenario ranges rather than hidden information.
