Ecosystem

The draft's leverage perimeter includes more than the headline platforms. The ecosystem reference should therefore remain explicit about both software assets and method references.

Direct And Indirect References

• Geometry and mechanical perimeter: OCCT, FreeCAD, OpenSCAD.
• Electrical and PCB perimeter: QElectroTech, KiCad, LibrePCB.
• Industrial and semantic standards perimeter: AutomationML, OPC UA, SysML v2, IFC, IEC CIM.
• Compiler and tooling perimeter: LLVM, MLIR, ANTLR, Tree-sitter, LSP.
• Storage, analytics, and graph perimeter: SQLite, DuckDB, Neo4j.
• UI and runtime perimeter: Kotlin Multiplatform, Compose Multiplatform, WASM, Skia, WebGPU.
• Visualization and digital-twin perimeter: OpenUSD, Blender, OpenBOM.
• Governance and project-structure references: Kubernetes, Git, Rust, Linux Foundation, Apache-style open project structure.

Method Reminder

Every ecosystem item should be tagged by method: direct use, integration, study, or standards reference. That method classification is part of the architecture, not editorial decoration.
