Known limitations

Early development; compatibility and desktop platform support are maintainer-reported. No .slx/.mdl import or code generation is documented. Multirate and zero-crossing rigor, subsystems, M-function blocks and WebAssembly support remain unfinished. Uses its own JSON model format rather than native Simulink projects.
