Regression Checklist

Check	Result	Notes
Azure Private without external DNS provisions	PASS	Scenario 1 — cluster Available=True, all 21 COs healthy
KAS defaults to Route for Private topology	PASS	Scenario 2 — all 4 services use Route strategy
CPO skips external routes when no hostname	PASS	Scenario 3 — only internal route exists
Private DNS zone uses correct naming	PASS	Scenario 4 — {name}.{baseDomain} (no -azurecluster suffix)
Guest dns.cluster has both zones	PASS	Scenario 5 — publicZone and privateZone both present
PublicAndPrivate topology unaffected (unit tests)	PASS	CLI fixture tests pass for all topologies
IBMCloud BaseDomain handling preserved	PASS	DNS config test: hcp.Spec.DNS.BaseDomain used directly for IBM
AWS SharedVPC PrivateZoneIAMRole preserved	PASS	DNS config test: SharedVPC sets PrivateZoneIAMRole
Non-Private callers pass isPrivate=false	PASS	Unit tests confirm non-Private uses LoadBalancer for KAS
Ingress ClusterOperator healthy	PASS	Available=True, Degraded=False, no issues with public zone
