Every ChartAnnotation carries a tenantId ensuring that your organization's site event markers — such as remediation milestones, regulatory actions, or equipment maintenance notes — are visible only to your users. When a compliance user views a site's concentration trend chart, only ChartAnnotations matching the current tenant's tenantId are rendered. This isolation ensures that sensitive operational context documented in annotations cannot be seen by other organizations using the platform.

Chart Annotation Tenant
The `tenantId` on a ChartAnnotation scopes the event marker to a single organization so annotations are never shared between tenants.
