🔬 OCCT precision burn-in
OCCT B-rep engine: 11/11 burn-in scenarios pass (cube / cylinder / sphere / boolean / fillet / chamfer / shell / sweep / loft / draft / helix). STEP export round-trip 100% accurate.

⚠ Honest limits
- CFD/MBD/CAM/Mold/Optics/Thermal solvers — Adapter interface only — activates when OpenFOAM/Chrono/OpenCAMLib Docker containers are wired
- Turbine-blade-grade G2/G3 surfaces — NURBS continuity analysis works; actual fairing relies on OCCT
- 100+ part assembly perf — BVH + sparse adjacency built; measured for 100-200 parts pending
- Multi-tab CRDT live edit — V1 skeleton only (presence + lock); full live-edit pending Yjs integration
- LLM engineering judgment — Catalog RAG covers bearings/seals/materials; design correctness still requires human review
