Module 2 · Recall check

1. You ship a chart where `values.yaml` has a top-level `replicas` field. A user writes `--set replicas=5`; the next version of your chart renames that field to `replicaCount`. What's the user-facing impact?

2. Which override source has the highest priority when rendering a chart?

3. You run `helm install demo ./chart -n prod --dry-run --debug`. What does this actually do against the cluster?

4. What does `helm rollback my-release 3` actually do?

5. A chart's `templates/service.yaml` wraps its whole body in `{{- if .Values.service.enabled -}} ... {{- end -}}`. A user installs with `--set service.enabled=false`. What ends up in the cluster?
