# Stack and commands SBOM Nexus is a Python 3.11+ FastAPI service packaged with `uv` and Hatchling. The extraction slice uses SQLite through the standard library; PostgreSQL is a production-cutover gate, not an implied property of the current code. ```bash make install make test make lint make check make run make scan ``` Do not claim verification without running `make check` or naming the narrower checks that were actually run.
