- Update kmsvc-root (root.yaml) targetRevision: prod → main
- Update management-service app targetRevision: prod → main
- Build workflow already pushes images on main commits
- Homelab ArgoCD app (60-kmsvc-manage.yaml) watches main with auto-sync enabled
- image.pullPolicy: Always + tag: latest ensures fresh images on rollouts
