- CMake build system with vcpkg dependency management - libdmf-node: Node interface, port definitions, WebSocket control server, node runner with MXL lifecycle management - libdmf-engine: Graph model (nodes/edges CRUD, serialization), FlowManager (UUID + V210 NMOS flow definitions), ProcessManager (fork/exec node processes), ApiServer (REST API for graph control) - Passthrough node: reads V210 grains from MXL, copies, writes to MXL - Unit tests for Graph and FlowManager (6 cases, 21 assertions) - MXL SDK as git submodule (symlinked from extern/mxl)
