Flux

• Stage sources — Git, OCI, Bucket

  Point a stage straight at a Git/OCI/Bucket source, or render manifests first into an ExternalArtifact.

• Stages and sources

  The core — ordered stages applying Flux sources, with path, prune, patches, and substitution.

• StageSet vs Flux kustomize-controller

  Intra-release stages and gates versus per-Kustomization ordering.

• StageSet vs jsonnet-controller

  A jsonnet-native Flux applier versus a renderer-agnostic staged-delivery layer.
