…tic CRD generation Bump the openshift/controller-tools replace directive from 24f590ca0886 to b0865777b142 (openshift fork PR openshift#35, upstream controller-tools openshift#1299), which switches pkg/crd/schema.go from the unstable sort.Slice to slices.SortStableFunc when ordering schema markers. With two or more same-gate FeatureGateAwareXValidation markers on a type, the markers all tie at ApplyPriorityFirst. The previous unstable sort, seeded by randomized Go map-iteration order, reordered those ties differently on each run, churning x-kubernetes-validations in the featuregated CRD manifests and breaking verify-git-clean. The stable sort preserves source order for ties, making generation deterministic. This fix commit's transitive requirements (gengo, kube-openapi) are older than or equal to what hack/tools already vendors, so no other dependency is bumped and both controller-gen and codegen continue to build under -mod=vendor. The featuregated manifest changes are a one-time reordering as the rules settle into stable source order; regenerating twice back-to-back now produces identical output.

…Minimal policy
Add a feature-gated HostedCluster/HostedControlPlane spec field
controlPlaneAvailabilityZoneScheduling {policy: Minimal, nonZonalPlacement} with
HA-only and Azure-only CEL, a feature gate, a status condition type, and
node-role label constants; regenerate CRDs, deepcopy, and featuregated manifests.
Under the Minimal policy, CPOv2 replaces podAntiAffinity with
topologySpreadConstraints (etcd strict minDomains=3; non-quorum pairs use
matchLabelKeys=pod-template-hash; float best-effort zone plus hard host spread),
adds zonal/overflow node affinity, scopes colocation per tier, and reduces
non-quorum API-critical components from three replicas to two. The
hypershift-operator copies the policy HC->HCP with dedicated-request-serving
precedence and reports the ControlPlaneAvailabilityZoneSchedulingAvailable
condition (mutual exclusion plus node-contract validation).
The HA-only and Azure-only constraints are expressed as two separate
FeatureGateAwareXValidation markers; with the deterministic controller-tools
sort they generate in stable source order.

Included review availability: Your plan provides up to 12 included reviews per hour; 11 remain after this review. 📝 WalkthroughWalkthroughThis change adds Minimal control-plane availability-zone scheduling for Azure. It defines API fields, labels, policies, validation, feature gates, and CLI options. HostedCluster reconciliation evaluates management-cluster node requirements and propagates scheduling settings to HostedControlPlane. Control-plane components receive scheduling tiers, placement rules, topology spread constraints, colocation rules, and updated replica defaults. Azure lifecycle tests cover deployment behavior, condition status, and node-label cleanup. Sequence Diagram(s)sequenceDiagram

Full details: Stable And Deterministic Test NamesExplanation The PR introduces a non-static Ginkgo test title at Full details: Test Structure And QualityExplanation The new Ginkgo coverage violates setup/cleanup and assertion-message requirements. Resolution Retain and register the node-label cleanup with a lifecycle teardown mechanism, or avoid mutating existing cluster-scoped Nodes. Invoke cleanup on normal completion and setup failure, and report restoration errors. Add meaningful failure messages to every Gomega assertion in Full details: No-Sensitive-Data-In-LogsExplanation The PR adds error paths that can log internal node hostnames. Resolution Do not include node names or unsanitized Kubernetes API errors in errors that reach the process logger. Replace the node-name-bearing messages and sanitize or classify the wrapped API errors before returning them. Apply the same treatment to the lookup, labeling, and cleanup error paths.

In `@docs/content/reference/hostedcluster-bringup-phases.md`:
- Around line 7-10: Update the HostedCluster phase-duration calculation to use
recorded condition transition history rather than only the current
status.conditions[*].lastTransitionTime values. Capture each gate’s first
sustained transition timestamp from watch or metrics history, including
transitions such as Available recovering from False to True, and calculate
consecutive phase deltas from those preserved timestamps.
In `@test/e2e/v2/lifecycle/azure.go`:
- Around line 209-213: Update AzurePlatformConfig.PreCreate and the
minimal-zonal setup around LabelManagementNodesForZonalScheduling so preparation
errors disable or skip the minimal-zonal variant instead of returning nil while
leaving it enabled. On success, retain the returned cleanup and register it with
lifecycle teardown; ensure makeCleanup records each label’s prior existence and
value, restores that state, stops on non-NotFound Get errors, and propagates
Patch errors.
In `@test/e2e/v2/tests/control_plane_workloads_test.go`:
- Line 1118: Move MinimalZonalSchedulingTest out of the generic control-plane
registration at test/e2e/v2/tests/control_plane_workloads_test.go:1118. In
test/e2e/v2/tests/minimal_zonal_scheduling_test.go:80-81, add

[sig-hypershift][Jira:Hypershift][Feature:MinimalZonalScheduling].
In `@test/e2e/v2/tests/minimal_zonal_scheduling_test.go`:
- Around line 104-106: Update
test/e2e/v2/tests/minimal_zonal_scheduling_test.go:104-106 to apply the existing
platform/version guards and fail, rather than skip, when supported workloads
have no pods; at 146-148 fail when etcd is absent, at 164-166 fail when
kube-apiserver is absent, and at 177-179 fail when kube-controller-manager is
absent. Ensure all required pod lists and named-resource searches assert
non-empty/found results to prevent vacuous passes.

Preserve and enforce the minimal-zonal node-label lifecycle.
When node preparation fails, AzurePlatformConfig.PreCreate logs the error and returns nil, so the minimal-zonal variant remains enabled without its three-zone contract. Skip that variant when preparation fails; its etcd configuration requires three replicas with DoNotSchedule and MinDomains=3.
When preparation succeeds, retain the returned cleanup and register it with lifecycle teardown. Record each label’s prior existence and value, then restore that state. makeCleanup currently removes pre-existing role labels, continues after non-NotFound Get errors, and discards Patch errors.

- Move MinimalZonalSchedulingTest into its own Describe with the required Sippy annotations ([sig-hypershift][Jira:Hypershift][Feature:MinimalZonalScheduling]) via RegisterMinimalZonalSchedulingTests, and add its label to the minimal-zonal test matrix filter; drop it from the generic control-plane-workloads registration. - Fail rather than skip when etcd, kube-apiserver, or kube-controller-manager are absent (they are guaranteed on a HighlyAvailable cluster), and apply the standard platform/version guards to the per-workload check. - Make the Azure PreCreate node-labeling fatal instead of silently continuing with the minimal-zonal variant still enabled (the variant cannot be skipped from PreCreate; ClusterSpecs is consumed first and there is no teardown hook). - Make the node-label cleanup restore each label's prior existence and value, ignore NotFound, stop on other Get errors, and propagate Patch errors. - Remove docs/content/reference/hostedcluster-bringup-phases.md, an unrelated file accidentally swept into the feature branch.

… in Default featureset Force-enables the ControlPlaneAvailabilityZoneScheduling feature gate in the Hypershift Default featureset manifest so the Default (non-TechPreview) CRD carries the spec.controlPlaneAvailabilityZoneScheduling field and its CEL rules. This lets the existing e2e-v2-azure-self-managed lane -- which installs the HyperShift operator with the Default featureset (TechPreviewEnabled=false) -- actually exercise the Minimal control plane availability-zone scheduling policy instead of silently pruning the field on admission and skipping every verification test. Context: the feature is purely CRD-gated (no runtime featuregate checks), so moving the gate to "enabled" in the Default manifest and regenerating is sufficient to make the code path testable without any openshift/release CI change. The API markers (+openshift:enable:FeatureGate and the two FeatureGateAwareXValidation CEL rules) are intentionally left intact. This commit MUST NOT ship. Revert the gate back to "disabled" and regenerate before merging. Real end-to-end validation of a TechPreviewNoUpgrade-only feature belongs in a dedicated TechPreview-enabled e2e lane (mirroring e2e-aws-techpreview), not in the Default featureset.

Execute the returned cleanup from the Azure lifecycle teardown.
LabelManagementNodesForZonalScheduling returns the only function that restores labels. The shown caller in test/e2e/v2/lifecycle/azure.go:196-220 discards it. Successful setup and partial setup failures therefore leave node-role labels on the management cluster.
Register the cleanup with the lifecycle teardown mechanism and propagate its error.
As per path instructions, lifecycle helpers that mutate node labels must capture and restore prior state, tolerate deleted resources, and report cleanup errors.

Use a timeout-bound context for cleanup API calls.
makeCleanup uses context.Background() for both cl.Get and cl.Patch, so cleanup has no cancellation or deadline and can exceed the lifecycle cleanup budget. Create one timeout-bound context for the cleanup operation and use it for both calls.

…orkloads
The per-workload "tier-consistent placement and spreading" assertion iterated
every Deployment/StatefulSet in the workload registry and required the
hypershift.openshift.io/control-plane-scheduling-tier label on each. But the
Minimal control plane availability-zone scheduling tier is stamped by the
control-plane-operator only on the components it manages. Components owned by
other operators are scheduled by those operators' own images (pulled from the
release payload), which do not yet carry this feature:
- cluster-network-operator children: ovnkube-control-plane,
multus-admission-controller, network-node-identity,
cloud-network-config-controller (handled by the CNO change, not yet merged)
- cluster-storage-operator children: azure-disk/azure-file CSI driver
controllers and operators, csi-snapshot-controller
Skip workloads whose top-level controller is not labeled
hypershift.openshift.io/managed-by=control-plane-operator so this lane reflects
what the CPO image can actually deliver. The cross-repo components are covered
by their own operators' tests; once the CNO change merges and lands in the
payload, its network components can be re-included via a dedicated check.

build(tools): bump controller-tools to stable-sort fix for deterministic CRD generation
Bump the openshift/controller-tools replace directive from 24f590ca0886 to
b0865777b142 (openshift fork PR #35, upstream controller-tools #1299), which
switches pkg/crd/schema.go from the unstable sort.Slice to slices.SortStableFunc
when ordering schema markers.
With two or more same-gate FeatureGateAwareXValidation markers on a type, the
markers all tie at ApplyPriorityFirst. The previous unstable sort, seeded by
randomized Go map-iteration order, reordered those ties differently on each run,
churning x-kubernetes-validations in the featuregated CRD manifests and breaking
verify-git-clean. The stable sort preserves source order for ties, making
generation deterministic.
This fix commit's transitive requirements (gengo, kube-openapi) are older than
or equal to what hack/tools already vendors, so no other dependency is bumped
and both controller-gen and codegen continue to build under -mod=vendor.
The featuregated manifest changes are a one-time reordering as the rules settle
into stable source order; regenerating twice back-to-back now produces identical
output.

feat(scheduling): add ControlPlaneAvailabilityZoneScheduling API and Minimal policy
Add a feature-gated HostedCluster/HostedControlPlane spec field
controlPlaneAvailabilityZoneScheduling {policy: Minimal, nonZonalPlacement} with
HA-only and Azure-only CEL, a feature gate, a status condition type, and
node-role label constants; regenerate CRDs, deepcopy, and featuregated manifests.
Under the Minimal policy, CPOv2 replaces podAntiAffinity with
topologySpreadConstraints (etcd strict minDomains=3; non-quorum pairs use
matchLabelKeys=pod-template-hash; float best-effort zone plus hard host spread),
adds zonal/overflow node affinity, scopes colocation per tier, and reduces
non-quorum API-critical components from three replicas to two. The
hypershift-operator copies the policy HC->HCP with dedicated-request-serving
precedence and reports the ControlPlaneAvailabilityZoneSchedulingAvailable
condition (mutual exclusion plus node-contract validation).
The HA-only and Azure-only constraints are expressed as two separate
FeatureGateAwareXValidation markers; with the deterministic controller-tools
sort they generate in stable source order.
