📝 WalkthroughWalkthroughCentral deletion now checks the ArgoCD Application, synchronizes its rollout group, and waits for the Central version-selector label to match before removing resources. Test utilities apply the label, and a regression test covers stale-label behavior. ChangesCentral deletion synchronization
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to The delete flow can read the wrong Central resource when multiple Centrals share a namespace, causing the wrong version selector to be updated; the lookup and regression test should be fixed before this PR is merge-ready.

- Around line 352-365: Update the reconciler lookup around centralCRList to use
client.Get with remoteCentral.Metadata.Namespace and
remoteCentral.Metadata.Name, rather than listing and selecting the first Central
CR. Return synchronized only when the named resource produces an IsNotFound
error; otherwise preserve error propagation and compare the retrieved resource’s
version-selector label with expected. Add a regression test covering two Central
CRs in the same namespace.

Read the target Central CR by name.
Use client.Get with remoteCentral.Metadata.Namespace and remoteCentral.Metadata.Name. Treat only IsNotFound as synchronized. Add a regression test with two Central CRs in the namespace.

The following was generated by
@coderabbitaiand may be updated automatically.Summary
Updated Central deletion handling to wait for the live Central CR to use the configured rollout group before deleting resources. The reconciler now checks for the ArgoCD Application and synchronizes the version-selector label. Added regression coverage and shared label constants.
