Just want to confirm the thinking on jwkCertURL as a CR field. jwkCertSecretRef I buy, air-gapped is real partner intent. When does a partner have an OIDC issuer that doesn't serve .well-known? Reading the tests, its main job is letting fixtures skip the network call.

Every field here is a forever contract (ADR-0019 is pretty explicit about keeping the CR minimal), and per ADR-0020 the gateway owns JWT validation, in-app is defense-in-depth, so this grows the contract to configure the fallback layer. Adding later is compatible, removing isn't. Could we keep discovery + Secret as the two paths for v1alpha1 and leave the URL out until someone actually needs it? If it stays, the CA-file question from the discovery comment will show up as a third field pretty quickly.

Scope Secret permissions to the operator namespace.

manager-role is bound by ClusterRoleBinding, so its get, list, and watch permissions allow controller-manager to access Secrets in every namespace. The controller reads referenced Secrets only from OperatorNamespace. Split the Secret rule into a namespaced Role, unless cluster-wide access is required and documented. This is CWE-250.

In `@config/rbac/role.yaml` around lines 20 - 27, Replace the cluster-wide Secret
permissions in manager-role with a namespaced Role scoped to OperatorNamespace,
preserving only get, list, and watch access for secrets. Update the binding
configuration so the controller uses this Role while retaining manager-role for
permissions that genuinely require cluster scope.

The comment is honest about what happens, but the CRD enum still accepts onprem-agent and bundle is immutable, so a partner who picks it gets a healthy-looking API that serves no routes and no signal why. Until the entity set exists I'd have Resolve (or Render) return an error for it, failing loudly rather than returning a nil that reads as success. 1409/1512 can turn that into a Degraded condition later.

// Intentionally empty: the on-prem/agent bundle's entity set is not yet
// defined. Leaving it nil renders no `entities:` key, and the API then
// registers NO entity types at all (LoadDescriptors ranges over the slice;
// there is no built-in default set), so it serves zero resource routes — it
// does NOT fall back to cloud-capi or any default entities. The on-prem
// bundle must supply an explicit entity set here before it is usable.

🎯 Functional Correctness | 🟠 Major | 🏗️ Heavy lift

Restore API entities for onprem-agent.

BundleOnPremAgent is accepted by the CRD and still resolves the API component. Returning nil omits entities from config.yaml, so the API registers no routes. This makes the deployed on-prem API unusable.

  • internal/bundle/bundle.go#L96-L103: Provide the required on-prem entity descriptors, or stop resolving the API component until the bundle is supported.
  • internal/bundle/bundle_test.go#L45-L52: Replace the nil-descriptor expectation with the supported on-prem descriptor contract.
  • internal/bundle/bundle_test.go#L83-L92: Assert the API component receives the supported on-prem descriptors.
