The sample.onprem.values.yaml and onprem-profile.values.yaml files for any release are bundled inside the Helm chart. To extract them, ensure you have authenticated with the Helm registry, then run:

VERSION=<VERSION> && \
TMP_DIR="/tmp/llmw-extract-$(date +%s)" && \
mkdir -p "$TMP_DIR" && \
helm pull oci://us-central1-docker.pkg.dev/pandoras-tamer/charts/llmwhisperer \
  --version $VERSION --untar --untardir "$TMP_DIR" && \
cp "$TMP_DIR/llmwhisperer/sample.onprem.values.yaml" "./sample.onprem.values-$VERSION.yaml" && \
cp "$TMP_DIR/llmwhisperer/resource-values/onprem-profile.values.yaml" "./onprem-profile.values-$VERSION.yaml" && \
rm -rf "$TMP_DIR"

Replace <VERSION> with the target release version (e.g., 2.56.4).
