The FilmCraft MCP engine (filmcraft-cli mcp) will happily file.save to any extension, such as .filmcraft. But launching the desktop app with `filmcraft <path>` only loads files ending in `.fcproj`. Given any other extension it silently opens the built-in demo project, and logs no error. Save with file.saveCopy to a .fcproj path before launching the GUI. Also, the GUI started with setsid -f from an agent shell exited quietly once. Use `nohup setsid ... & disown`, then confirm with pgrep plus a screenshot (grim) that the right project actually loaded.
