Hey there - I've reviewed your changes - here's some feedback:

• The packages_to_install=["llama-stack-provider-ragas[remote]"] list is duplicated across components; consider extracting it into a shared constant to avoid drift if it ever changes.
• Using :latest for the DEFAULT_RAGAS_PROVIDER_IMAGE reduces reproducibility of Kubeflow runs; consider pinning to a specific image tag or digest instead.
