## Integration Patterns

| Pattern | When | Tool |
|---------|------|------|
| CI-triggered refresh | On deploy | GitHub Actions |
| Scheduled pipeline | Daily/weekly reports | Cron, Airflow |
| On-demand run | User-triggered analysis | API endpoint |
| Orchestrated pipeline | Multi-step ETL | Airflow, Dagster |
