## Summary by CodeRabbit
* **Bug Fixes**
* Host vitals labels based on identity-provider group membership now
correctly apply to both global and team-scoped hosts, preventing
cross-team leakage.
* **Tests**
* Added and updated tests to validate IdP-group-backed vitals label
membership across global and per-team hosts.
