# Validation evidence (Steps 3 and 4)

The committed validation suite covers:

- input contract failures and successful normalization;
- deterministic TSD generation and required headings;
- parseable native draw.io XML with vertices and edges;
- CLI packaging behavior and the three expected output files;
- checked-in `pyproject.toml`, configuration, example, specification, and source layout.

Run `python -m unittest discover -s tests -v` from the repository root. Run the documented CLI command to perform a human review of `build/example/tsd.md` and open `build/example/architecture.drawio` in diagrams.net. Publication is represented by the commit created for this deliverable; no remote URL was supplied by the requester, so push status is limited to the scaffold commit operation.
