MechanismWorld data and code

MechanismWorld is a synthetic benchmark and reproducibility package for compositional mechanism dynamics, structural transfer, and instance recovery. The package contains synthetic scalar mechanism generators, frozen model and estimator implementations, configurations and weights, numerical results, and scripts for regenerating released arrays and figures. It supports the computational scope of the accompanying manuscript and does not claim hardware or experimental validation.
