- Rename status condition "Type" to "NetworkObservabilityInstalledByCNO" from "NetworkObservabilityDeployed" - In status condition, define 8 states (Reason). 1. FeatureGateDisabled 2. NoAction 3. SNO - Single Node OpenShift 4. InstallationInProgress 5. WaitingForOperator 6. Installed (terminal) 7. PreExisting (terminal) - If FlowCollector CRD exists, it goes to this state. 8. Failed (terminal) The last three states are terminal, meaning once they reach these states, it won't do anything more unless you reset and clear the status condition.

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win
Handle errors from setNetworkObservabilityCondition.
Each ignored update can leave the intended state transition unpersisted. If the installation condition is absent, isWaitingForOperator remains false, so the controller can reapply OperatorYAML on later reconciles. If the manifest creates the CRD while the condition writes fail, the next reconcile can classify that CNO-created CRD as PreExisting. A failed timeout update can also leave the controller in a non-terminal state because the method returns without requeueing. Later successful updates can still allow the state machine to reach Failed, so this is not unconditional.
Handle every ignored update. Return or requeue on errors. In shouldInstallNetworkObservability, return the update error so Reconcile schedules another attempt. The change is localized to this controller.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Migrate the legacy CNO ownership condition.
The previous controller set NetworkObservabilityDeployed=True after a successful installation, including when the FlowCollector CRD already existed. During an upgrade, that condition can remain on the Network resource. The new shouldInstallNetworkObservability checks only NetworkObservabilityInstalledByCNO, then writes NetworkObservabilityInstalledByCNO=False with reason PreExisting. The reported ownership status is incorrect. Translate NetworkObservabilityDeployed=True to NetworkObservabilityInstalledByCNO=True with reason Installed before checking for a pre-existing CRD.

With the Enable Network Observability feature (PR #2925),
oc describe network.operatorshows the status of Network Observability in certain conditions. Instead of indicating whether Network Observability is installed or not, it should show whether CNO installed NetworkObservability or not and if not, what's the reason. The states for these are:The last three states are terminal, meaning once they reach these states, it won't do anything more unless you reset and clear the status condition.
For the "PreExisting" state, it removes the OLMv0 and OLMv1 checks. This simplifies the code and test code significantly.
The status condition "Type" was changed to "NetworkObservabilityInstalledByCNO" from "NetworkObservabilityDeployed".
