📐 Maintainability & Code Quality | 🟠 Major | ⚡ Quick win

Add repeatable validation for the new release.

This change adds a Helmfile release and changes the default environment. Add a repository-native render or lint test that checks the condition, chart version, namespace, and image values, or explain in the Pull Request why tests are not applicable. Run the repository-native test runner before committing.

As per coding guidelines: “Code changes must include tests, or the Pull Request must explain why tests are not applicable; run the repository-native test runner before committing.”

If such validation is genuinely not applicable, document that rationale in the pull request instead.

NVIDIA nvcf helm-event-ledger 0.1.0-test chart

💡 Result:

The NVIDIA Cloud Functions (NVCF) platform maintains an internal component referred to as the Event Ledger [1]. Recent technical documentation and development activity indicate that the Event Ledger is an internal service within the NVCF control plane ecosystem, currently undergoing refactoring to decouple it from proprietary authorization services [1]. While there are numerous documented Helm charts for the NVCF self-hosted stack (e.g., helm-nvcf-api, helm-nvcf-nats, helm-nvcf-invocation-service) [2][3][4], there is no public-facing, standalone "nvcf helm-event-ledger 0.1.0-test" chart listed in the official NVCF manifest or the NGC catalog [2][5]. The Event Ledger is integrated into the broader NVCF control plane architecture rather than being distributed as a standalone, versioned test chart for general public use [1][3]. Development efforts, such as PR #256 in the NVIDIA/nvcf repository, focus on adding public Go interfaces (e.g., Authorizer) to allow the Event Ledger to function with pluggable identity providers, specifically to support open-source builds [1]. You may find related logic within the nvcf source code repository, but it is not provided as an independent Helm chart with the specified version [1][6].

Do not enable event-ledger in the default environment.

base.yaml enables addons.eventLedger.enabled, so the default installation selects nvcf/helm-event-ledger:0.1.0-test. If the configured chart source does not contain this unreleased version, Helmfile cannot resolve the chart and installation fails. Disable the addon in the base environment until an officially published chart version is available.
