How these were built
The four projects share one spine: a self-hosting build-engine — a workflow engine whose own database stores its build process, with an HTTP edge and an MCP tool surface over one validated core. The four apps each carry a Rust → WebAssembly engine, so computation happens on your device and your data never leaves the page. The UI layer is dependency-free TypeScript — no framework. Each repository is small, tested, and CI-green; the build-engine even recorded its own RBAC feature as a Case you can read.
