• Kubernetes: Clusters
• M365: Tenants
• Github: Organizations / Repositories
• Oracle Cloud: Tenancies / Compartments
• Infra as Code: Repositories
• MongoDB Atlas: Organizations
• LLM: Models
• NHN: Tenants

2. Verify the table renders correctly with the new column
3. Confirm the audit scope values are accurate for each provider
