How can I continue?After more reviews become available, a review can be triggered using the To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews. How do review limits work?CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability. For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

- Around line 519-522: Update the cleanup handling around reconcileAgentCleanup
so its error is returned instead of only logged, preventing deprovisioning and
finalizer removal from succeeding while agent cleanup remains incomplete.
Preserve the existing successful cleanup flow and use reconcileAgentCleanup’s
returned error to trigger reconciliation retry.

…AgentCleanup Add agent selection to ClusterOrder controller: for each node set, the operator lists available Agent CRs matching the resource class, labels them with osac.openshift.io/clusterorder to reserve them for HyperShift NodePool claiming, and stores the selections in status.nodeSets. On deletion, reconcileAgentCleanup removes the clusterorder label from all allocated agents, returning them to the available pool. Uses unstructured objects for Agent CRs (agent-install.openshift.io/v1beta1) to avoid importing the assisted-service dependency tree, consistent with the MetalLB IPAddressPool pattern.

[medium] error-handling-gap
HostName is populated from the agent's netris.server/name label without checking for existence. AgentStatus.HostName has +kubebuilder:validation:Required and +kubebuilder:validation:MinLength=1, so agents missing this label produce an empty HostName that fails CRD validation on status patch, causing a permanent retry loop. Per osac-aap/docs/agent-labels.md, this label is optional for non-Netris backends, making the bug reachable in production.
Suggested fix: Check that the netris.server/name label exists and is non-empty before appending the AgentStatus.

[medium] constant-naming-convention
agentClusterOrderLabel (osac.openshift.io/clusterorder) duplicates osacClusterOrderNameLabel from clusterorder_names.go:21. New agent constants don't follow the osac prefix convention.
Suggested fix: Reuse osacClusterOrderNameLabel and adopt the osac prefix for other new constants.

[low] race-condition
selectAgents uses r.Client.Update (full object replacement) to label agents. Using r.Client.Patch with client.MergeFrom would reduce the conflict surface from concurrent Assisted Installer updates.

[low] edge-case
NodeSetStatus.Name is set to nodeReq.ResourceClass. Since NodeSets uses +listType=map with +listMapKey=name, duplicate ResourceClass values in NodeRequests would fail CRD validation.

[low] logic-error
Idempotency guard prevents re-selection if agents are removed or NodeRequests changes. Likely intentional but lacks explicit immutability validation on NodeRequests.

[low] log-message-formatting
Log key 'resourceClass' uses camelCase while existing code uses 'resource_class' (snake_case) for the same concept.

Add agent selection to ClusterOrder controller: for each node set, the operator lists available Agent CRs matching the resource class, labels them with osac.openshift.io/clusterorder to reserve them for HyperShift NodePool claiming, and stores the selections in status.nodeSets.
On deletion, reconcileAgentCleanup removes the clusterorder label from all allocated agents, returning them to the available pool.
Uses unstructured objects for Agent CRs (agent-install.openshift.io/v1beta1) to avoid importing the assisted-service dependency tree, consistent with the MetalLB IPAddressPool pattern.
