LMNTL-controlled Helm chart hosting, served via GitHub Pages at
https://lmntl-ai.github.io/helm-charts.
The spartan chart versions here are byte-identical mirrors of the artifacts
formerly consumed from the contractor-controlled host
https://spartan-stratos.github.io/helm-charts (supply-chain re-home, 2026-08-10,
epic LMNTL-AI/service-platform#1283 family). Digests verified against the upstream
index at mirror time AND recomputed locally from the tarball bytes:
Consumers: ArgoCD Applications in LMNTL-AI/infra-argocd (branches dev/prod),
Jenkins credential centralized-helm-chart-url + GH org variable HELM_REPO
(via LMNTL-AI/infra-terraform config/general/locals.tf).
New chart versions: add the .tgz, regenerate with
helm repo index . --url https://lmntl-ai.github.io/helm-charts, commit both.
Never modify an existing .tgz — versions are immutable.
