# jetstack/cert-manager@v1.20.2 Production Support Workdown

This generated page is a human workdown for one target-scoped production
support decision. It does not replace the source decision artifact:

[support-decision.yaml](./support-decision.yaml)

## Current Decision

| Field | Value |
| --- | --- |
| Chart | `jetstack/cert-manager@v1.20.2` |
| Candidate base | `crds-enabled` |
| Decision state | `supported` |
| Target scope | cub-lk-kind-vanilla; namespace=cert-manager; delivery=confighub-oci; controller=argo |
| Delivery path | `confighub-oci` |

## Open Work

| Work | Action |
| --- | --- |
| Keep fresh | Keep target-scoped evidence fresh before using this supported scope as an example. |


## Closeout Sequence

1. Keep the target-scoped evidence fresh for the declared support boundary.

## Required Before Final Support

- None.


## Support Boundary

Included:

- jetstack/cert-manager@v1.20.2 crds-enabled base
- ConfigHub OCI delivery through Argo for the declared cub-lk vanilla kind target scope
- rendered CRDs, controller workloads, webhook objects, labels, gates, receipts, and support objects produced by the recorded base
- recorded startup API check lifecycle route using post-apply server dry-run and observation, not direct Helm hook execution
- recorded mutable-image exception for the declared public controller support scope
- recorded resource-policy acceptance for the declared public controller support scope
- Kubernetes 1.35 selectableFields capability-profile witness for the rendered cert-manager CRDs

Excluded:

- private values overlays, wrapper charts, and populated extension slots unless separately reviewed
- the default no-CRD target-prerequisite posture unless separately reviewed for a specific target
- Issuer, ClusterIssuer, Certificate, CertificateRequest, ACME account, ingress-shim, Gateway API, and provider credential workflows
- digest-pinned, resource-hardened, or provider-specific production bases unless separately reviewed
- Kubernetes targets that drop selectableFields unless a profile-specific base or separate route is reviewed
- non-vanilla Kubernetes distributions unless separately reviewed
- other delivery controllers or target scopes unless separately reviewed

## Next Action

Keep the target-scoped evidence fresh before using this supported scope as a production-support example; create separate issuer, certificate, provider, or hardened resource bases for real customer certificate workloads.
