Compressor Pneumatic System Package
Calculates source-bound compressor and pneumatic system metrics from a deterministic SSC-06 task-owned source pack. The template combines adjusted air demand, compressor capacity margin, receiver storage runtime, motor input and margin, feeder voltage drop, branch pressure margin, 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.
