# Validation plan and report The repository validation covers: - Unit tests for required-field/type validation, TSD sections, and draw.io XML markers. - CLI packaging smoke test that writes all three expected files. - Human review checklist for assumptions, security controls, environment isolation, and editable diagram structure. Run `python -m unittest discover -s tests -v` and `python -m landing_zone_agent.cli --requirements examples/requirements.json --output-dir /tmp/landing-zone-agent-check`. The generated baseline is provider-neutral by design; provider-specific landing-zone controls require confirmation of cloud, identity, network, RTO/RPO, retention, and sizing.
