## Overview
Agents that work in a chemistry lab need more than meshes. They need to know that a fume-hood sash travels 673 mm and
stops at 457 mm, that moving a balance's draft-shield door restarts its stability check, and which quantities a policy
may observe and which are hidden ground truth kept for evaluation. ChemLab-Assets ships that knowledge with the geometry.
Each asset is one specific commercial instrument, chosen from a survey of 200 instruments and modules used in university
chemistry teaching and research, and built from published brochures, manuals and papers. The models reproduce documented
behaviour; they are not manufacturer CAD and have not been calibrated against physical units.
This repository holds the code (runtimes, tests, examples, contract validator), the catalog, the project website (`docs/`) and the 3D explorer (`explorer/`). The models and data (about 1.5 GB) live in the Hugging Face dataset; `python tools/download_assets.py` fetches them into `assets/`.
