Removed (application layer, not kernel): - blender_addon/ — Blender plugin - dotnet/ — .NET/C# bindings - viewer/ — Web 3D viewer - include/vde/ai/ — AI/ML (GNN, generative design) - include/vde/cloud/ — Cloud-native (OT, sessions) - include/vde/distributed/ — Cluster computing - include/vde/kbe/ — Knowledge-based engineering - include/vde/wasm/ — WASM compilation - include/vde/digital_twin/ — Digital twin - include/vde/plugin/ — Plugin system - include/vde/gpu/ — GPU acceleration - src/ai/, src/cloud/, src/distributed/, src/kbe/, src/wasm/, src/digital_twin/, src/plugin/, src/gpu/ - tests/ai/, tests/cloud/, tests/distributed/, tests/kbe/, tests/gpu/ Kept (pure geometry kernel): - brep/ curves/ mesh/ core/ foundation/ spatial/ boolean/ collision/ sdf/ sketch/ capi/ - python/ bindings (kept as thin binding layer) Rationale: Parasolid/ACIS/CGM are pure kernels.
