DataGuard AI — the agent that stops schema breaks before they ship

Watch the full three-minute walkthrough: a breaking column rename is detected, traced across DataHub lineage, healed in dbt and Airflow code, and shipped as a reviewable pull request — with tags, incidents and glossary terms written back to DataHub.

• Multi-hop lineage: PostgreSQL → dbt → Airflow → feature stores
• Healing agent patches SQL and Python, never merges on its own
• Governance write-back keeps DataHub the source of truth
