In-house charts have nowhere to publish: a helm local stores uploads but serves no index.yaml, and the helm virtual merger drops every chart field except name/version/urls. - add helm local uploads (`PUT .../files/<name>-<version>.tgz`) recording each Chart.yaml in a new `helm_metadata` table; mismatched filenames stay out of the index - bound chart parsing (50MiB decompressed, 10k entries, 1MiB Chart.yaml) - generate a deterministic `index.yaml` with sha256 digests and path-escaped relative urls - keep all chart fields when merging helm virtual indexes, expanding YAML aliases - add a real-helm e2e-docker test, UI snippet and README section Reviewed-on: #140 Co-authored-by: unkin-agent <unkin-agent@unkin.net> Co-committed-by: unkin-agent <unkin-agent@unkin.net>
