zeekayandHanzo Dev 446e343a3d cd: annotations are cd.hanzo.ai, API group is apps.hanzo.ai
Two corrections on top of the naming pass, both found by checking the live
cluster rather than the source.

The rename had silently changed the user-facing annotation key from
argocd.argoproj.io/sync-wave to cd.argoproj.io/sync-wave — 63 live
Applications carry the old key, so deploying that would have ignored every
sync-wave and broken fleet deploy ordering. The key is now cd.hanzo.ai/*,
and universe 575650286 moves the ApplicationSet template that stamps it, so
the controller regenerates all 63 consistently.

The API group in code said argoproj.io/v1alpha1 in 157 places while the
cluster has served apps.hanzo.ai/v1alpha1 since 2026-07-23 (the CRDs are
applications.apps.hanzo.ai). Code now matches what is actually served.

The legacy applications.argoproj.io/app-name label had ZERO live users, so it
went with the rest. foo.argoproj.io test fixtures became foo.example.com —
arbitrary test domains should not carry a vendor name.

go build ./... exit 0.

Core Concepts

Let's assume you're familiar with core Git, Docker, Kubernetes, Continuous Delivery, and GitOps concepts. Below are some of the concepts that are specific to Hanzo CD.

  • Application A group of Kubernetes resources as defined by a manifest. This is a Custom Resource Definition (CRD).
  • Application source type Which Tool is used to build the application.
  • Target state The desired state of an application, as represented by files in a Git repository.
  • Live state The live state of that application. What pods etc are deployed.
  • Sync status Whether or not the live state matches the target state. Is the deployed application the same as Git says it should be?
  • Sync The process of making an application move to its target state. E.g. by applying changes to a Kubernetes cluster.
  • Sync operation status Whether or not a sync succeeded.
  • Refresh Compare the latest code in Git with the live state. Figure out what is different.
  • Health The health of the application, is it running correctly? Can it serve requests?
  • Tool A tool to create manifests from a directory of files. E.g. Kustomize. See Application Source Type.
  • Configuration management tool See Tool.
  • Configuration management plugin A custom tool.
