300 prompts across Model, Set and Alt-Build settings.
Combines connection, collision and stability checks with VQA alignment and preference-calibrated Elo.
With the environment, leading agents usually build valid assemblies and satisfy up to about 95% of semantic requirements.
It closes the loop from executable programs to physical objects and multi-axis verification.
Verify hard constraints first, rank soft quality second, and return localized failures.
