 - Before editing a chart's `values.yaml`, check the schema for the exact chart/dependency version declared in its `Chart.yaml`. Prefer a schema shipped with that exact chart package; never use a schema from `main`, `latest`, or a different version as if it were authoritative.
 - Current chart schema/reference locations:
   - Cilium: `infrastructure/cilium/Chart.yaml` pins the Cilium dependency. Its matching upstream schema is [`values.schema.json` for Cilium v1.17.6](https://raw.githubusercontent.com/cilium/cilium/v1.17.6/install/kubernetes/cilium/values.schema.json). Keep this reference aligned with the dependency version when upgrading.
+  - cert-manager: `infrastructure/cert-manager/Chart.yaml` pins the Jetstack cert-manager chart. Its matching upstream schema is [`values.schema.json` for cert-manager v1.21.2](https://raw.githubusercontent.com/cert-manager/cert-manager/v1.21.2/deploy/charts/cert-manager/values.schema.json). Keep this reference aligned with the dependency version when upgrading; cert-manager's CRDs are enabled and retained by this chart.
   - Longhorn: `infrastructure/longhorn/Chart.yaml` pins the Longhorn dependency. The matching [v1.8.1 chart directory](https://github.com/longhorn/longhorn/tree/v1.8.1/chart) does not include `values.schema.json`; use that release's [`values.yaml`](https://raw.githubusercontent.com/longhorn/longhorn/v1.8.1/chart/values.yaml) and chart documentation alongside this repository's values and templates. Do not substitute a schema from another Longhorn release.
   - Vaultwarden: this is a repository-maintained chart under `services/vaultwarden/`, not an upstream chart dependency, and it currently has no `values.schema.json`. Use the [Gabe565 Vaultwarden chart values](https://github.com/gabe565/charts/blob/main/charts/vaultwarden/values.yaml) as a reference for upstream configuration options, but treat this repository's `services/vaultwarden/values.yaml` and templates as the actual contract. The upstream chart has its own structure and common-library dependency, so do not copy its values or assume they work here without checking the local templates. If changing or adding local chart values, add or update `services/vaultwarden/values.schema.json` to validate the local contract.
 - Pin versions for deployed software and build/deployment dependencies. Avoid `latest`, floating tags, and unversioned references; for container images, use an explicit version tag and prefer a digest where practical for immutable deployments. If a floating reference is necessary, explain why and its update risk.

-Talos uses its default CNI during bootstrap so Argo CD can start. Cilium is then reconciled as the first infrastructure application. Cilium's Envoy ingress controller is enabled in shared-load-balancer mode; Ingress resources must set `spec.ingressClassName: cilium`. The Cilium LoadBalancer IP pool is `10.0.0.10–10.0.0.89`, announced over `enp1s0` with an L2 announcement policy. Keep that range reserved from DHCP and other static assignments, and recheck the interface and pool if the node network changes. Longhorn also requires a validated disk or mount on the storage node.

+cert-manager is installed from the pinned Jetstack chart under `infrastructure/cert-manager/`, with its CRDs enabled and retained on uninstall. This installs the certificate controller but does not create an Issuer, ClusterIssuer, or application Certificates; configure those resources and any required DNS or ACME account settings before requesting certificates. The chart version is pinned in `infrastructure/cert-manager/Chart.yaml`; use the matching [cert-manager v1.21.2 values schema](https://raw.githubusercontent.com/cert-manager/cert-manager/v1.21.2/deploy/charts/cert-manager/values.schema.json) and [Helm installation documentation](https://cert-manager.io/docs/installation/helm/) when changing chart values. Longhorn also requires a validated disk or mount on the storage node.
 
 The Terraform Talos provider uses one generated machine-secrets bundle for the whole node list. If the nodes were previously configured with another Talos CA, reset/reinstall them or restore the matching Terraform state before applying. Terraform state contains the generated Talos credentials and must remain private.
