📝 WalkthroughWalkthroughThe API adds controller-computed control-plane topology transition status with availability, reason, and message fields. Infrastructure and ControllerConfig CRD schemas expose the field with enum, format, length, conditional, list-size, and uniqueness validation. Mutable topology tests cover valid entries and invalid values, missing reasons, malformed reasons, message limits, and duplicate source-target pairs. Suggested reviewers: Merge Risk: 🟡 Moderate · up to The new status API can publish impossible or inapplicable topology transitions, causing consumers to act on misleading transition availability.

Enforce the transition invariants in InfrastructureStatus.
The item-level validation does not link controlPlaneTopologyTransitions to status.controlPlaneTopology. The current fixture accepts both a mismatched source and source == target. Add an InfrastructureStatus-level CEL rule so every entry satisfies t.source == self.controlPlaneTopology && t.source != t.target. Regenerate the CRDs and add fixture cases that reject both forms.

…tatus Adds a new feature-gated InfrastructureStatus field that reports, as controller-computed observed state, the control-plane topology transitions available from the cluster's current topology and whether each can currently be initiated (Available/Unavailable/Unknown, with a CamelCase reason and human message when blocked). Gated behind the existing MutableTopology feature gate. Regenerates deepcopy, OpenAPI, swagger docs, and CRD manifests (including the embedded ControllerConfig schema, which pulls in InfrastructureStatus).

Enforce both transition invariants at the status schema boundary
The generated CRD accepts self-transitions and entries whose source differs from status.controlPlaneTopology. The repository tests explicitly record these values as schema-permitted, although the controller would not emit them. A consumer can therefore receive an entry that does not describe a transition from the current topology. Add item-level CEL validation for source != target and status-level validation that every source equals status.controlPlaneTopology, then regenerate the gated CRDs.

Summary
Adds a new
status.controlPlaneTopologyTransitionsfield to theInfrastructureAPI. It reports, as controller-computed observed state, the control-plane topology transitions available from the cluster's current topology (e.g.SingleReplica->HighlyAvailable) and whether each can currently be initiated:availability:Available|Unavailable|Unknownreason: CamelCase machine-readable explanation, required when notAvailablemessage: human-readable detail, primarily forUnavailabletransitionsThe field is gated behind the existing
MutableTopologyfeature gate (already registered, previously ungated). It advertises discovery of available transitions; it does not itself trigger one — transitions are still requested viaspec.controlPlaneTopology. It is advisory: the cluster may change between a status read and a spec write, so the cluster-config-operator revalidates any requested transition.This is the concrete realization of the Mutable Topology enhancement's dev-preview graduation criterion: "Valid and invalid cluster transitions are identified in the infrastructure status."
