Restrict replacement to the Istio resource spec.version.
Line 317 replaces every indented version: key in a selected YAML file. The file checks do not bind that key to an Istio or IstioCNI resource. A different nested version: field can therefore be overwritten with the Istio release value.
Parse each YAML document and update only spec.version for kind: Istio and kind: IstioCNI.

Read the MCPGatewayExtension CRD via `helm show crds` against the exact chart being installed (OCI ref+version or local nightly chart path), instead of querying CRDs already registered on the cluster. This makes the result depend only on what this run is installing, unaffected by any leftover/orphaned CRDs from prior installs on a shared cluster. Also actively prune any MCPGatewayExtension-family CRD (and lingering CR instances) whose API group doesn't match the group the current chart uses, so the cluster converges to what the chart defines instead of accumulating stale state across chart versions (e.g. the old mcp.kagenti.com group).

apply_infrastructure hardcoded apiVersion: <group>/v1alpha1 for the MCPServerRegistration manifest, but the mcp-gateway chart now serves v1 for this CRD too. Detect the actual storage version straight off the installed CRD instead, mirroring the MCPGatewayExtension fix. Safe here because apply_infrastructure only runs after install_platform has finished installing/pruning CRDs for the current chart. Also applies `ruff format` to the previous CRD-detection changes.

Propagate the chart API group into apply_infrastructure.run.
If the toolbox uses its default api_group with a mcp.kagenti.com chart, _detect_crd_storage_version queries the wrong CRD, and line 267 generates mcp.kuadrant.io/v1alpha1. Kubernetes cannot map this object to the installed CRD. Derive and pass the chart API group with its storage version.

Fail when stale CRD deletion still times out.
Line 251 ignores the result of the final deletion wait. Line 253 then returns the CRD as removed. The caller logs a successful prune and creates the new extension while the stale CRD and instances can still exist.
Raise RuntimeError when the second wait_for_crd_deletion call returns False. This matches the failure behavior in projects/mcp_gateway/toolbox/cleanup_platform/main.py.

Kubernetes kubectl resource.group fully qualified resource name API group discovery same plural official documentation
💡 Result:
To refer to Kubernetes resources with precision in kubectl, you can use a fully qualified resource name, which allows you to specify the resource, its API version, and its API group [1]. The standard syntax for a fully qualified resource name in kubectl is: TYPE[.VERSION][.GROUP] For example, to list deployments specifically in the v1 version of the apps API group, you would use: kubectl get deployments.v1.apps Key details regarding this discovery and naming mechanism include: 1. Fully Qualified Naming: While kubectl often allows the use of simple resource names (like pods or deployments), appending the version and group ensures you are targeting the exact API endpoint desired [1]. This is particularly useful to resolve potential name clashes when different API groups share similar resource names [2]. 2. Discovery API: Kubernetes uses the Discovery API to provide clients like kubectl with a list of all supported API groups, versions, and resources [3]. You can inspect the resources available in your specific cluster by running the following command [4][5]: kubectl api-resources 3. Plural Forms: The TYPE in the syntax above generally refers to the plural name of the resource (e.g., deployments, services, pods) [1][6]. The kubectl api-resources command output displays the official plural names for every resource type available in your cluster [4][7]. 4. API Groups: API groups are collections of related functionality within the Kubernetes API (e.g., apps, rbac.authorization.k8s.io) [2][8]. You can filter the output of the api-resources command to see only resources associated with a specific group using the --api-group flag [4]: kubectl api-resources --api-group=apps By utilizing the fully qualified syntax (TYPE.VERSION.GROUP), you bypass ambiguity and ensure kubectl interacts with the intended API resource definition [2][1].

Use the fully qualified CRD name when removing finalizers.
Both helpers pass only the plural resource name to oc. When both API groups exist, oc can select the wrong CRs, leaving finalizers on the stale CRs and causing CRD deletion to remain stuck. Pass crd_name to oc get and each oc patch in both helpers.
