Morphir is a FINOS-hosted toolchain for capturing business logic as a language-agnostic Intermediate Representation (IR). It compiles source code (Elm, Gleam) into a typed IR, supports code generation for multiple backends (OpenAPI, Avro, Python, Rust), evaluates IR expressions, manages packages with TUF-signed metadata, and runs a conformance test kit (MCK) to verify IR adapter implementations. The architecture is a monorepo with a Rust CLI (`morphir`), a web UI server (JSON-RPC over WebSocket), a Docusaurus documentation website, and submodules for language backends. Key entry points include the CLI binary (`crates/morphir/src/main.rs`), the MCK engine (`crates/morphir-mck/src/lib.rs`), and the web UI server (`crates/morphir/src/commands/ui/server.rs`). The system relies on external compilers (Elm, Gleam), WASM extensions, and subprocess adapters for conformance testing. The repository is actively maintained with recent commits, low technical drift, and a well-structured codebase.
