+Recent additions such as `Context Engine`, `Current Input File / Tool Reference`, `History Analyzer`, and `Release Readiness` are now shown above; the offline tools are listed as sidecars and are not on the request path.

 For the full module-by-module architecture and directory responsibilities, see [docs/ARCHITECTURE.en.md](docs/ARCHITECTURE.en.md).
 
 - **Backend**: Go (`cmd/ds2api/`, `api/`, `internal/`), no Python runtime
