A HorizontalPodAutoscaler changes a workload's desired replica count from observed metrics. It doesn't create nodes or repair an application that can't start. Some application work sits outside a single Pod manifest. Helm manages versioned packages as releases; Kustomize composes plain resource bases and overlays. YAML syntax is only the first validation boundary. A document can parse and still use an unsupported API version, a wrong field type or a workload policy that violates its request.
Apply those boundaries to fresh fixtures. Inspect the requested name, namespace, path and value before reusing a command. The tasks mix earlier operations and include nearby wrong targets, so preserve unrelated work. Choose any supported approach that produces the complete requested state; the checker evaluates the result rather than a recorded command sequence.
