Lift Shaft Car Accessibility Service Package
Calculates source-bound vertical transport metrics from a deterministic SSC-08 task-owned source pack. The template combines car dimension margins, shaft clearance margins, accessible lift capacity, generator allocation, feeder current, voltage-drop 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.
- easy:
- All source-pack values given for the SSC-08 lift accessibility package
- medium:
- All source-pack values given for the SSC-08 lift accessibility package
- hard:
- All source-pack values given for the SSC-08 lift accessibility package
