This PR makes ClusterExtension.spec.namespace optional by introducing “managed namespace” behavior resolved from bundle CSV annotations (including PSA label support), and updates reconciliation + tests/docs accordingly.
Changes:
- Add managed-namespace resolution from bundle metadata with a fallback chain and persist the resolved namespace in status.
- Inject a managed Namespace object (with collision protection) and support applying PSA labels via
suggested-namespace-template. - Expand E2E/unit tests and update CRD schema/docs to reflect optional namespace + immutability rules.

I think we may want to refactor to deprecate spec.namespace, register a new field in the registry+v1 config schema for namespace. And then implement the logic on the bundle converter, which already reads and applies the config.
Would that work?
we had originally planned the deprecation and removal to be phase 2, once we confirm everything else looks okay, will go ahead with that change |

Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🟡 Moderate · up to This PR changes namespace resolution and validation behavior, but the current implementation may serialize an omitted namespace incorrectly, allow managed-namespace collisions between distinct packages, and emit invalid CEL validation markers.

maybe we could make a self-managed namespace generator function and add it to the rest collection of generator and basically use this implementation within it? (i.e. selfManagedNamespace is set - produce the object, if not, bail). Wdyt?

In principle, it probably doesn't need to be a terminal error, i.e. the user could create the namespace and everything works on the following retry
Replace Render's special-cased namespace handling with a BundleInstallNamespaceGenerator and split the concern into two options (WithInstallNamespace, RenderInstallNamespace); resolution/defaulting and option validation happen in Render. Rendered output is unchanged. Also make ValidateInstallNamespace return a retryable error instead of a terminal one when a user-provided spec.namespace does not exist, so the controller requeues once the namespace is created.

- Around line 71-78: Update the Namespace field validation in the standard CRD
schema to reject empty values, while preserving the existing experimental
validation behavior. Change its JSON tag to use omitempty so empty namespaces
are omitted from serialization.
Apply the same fix in
`@helm/olmv1/base/operator-controller/crd/standard/olm.operatorframework.io_clusterextensions.yaml`
around lines 124 - 128: The generated standard CRD contains the same
empty-string exception.
Apply the same fix in `@manifests/standard-e2e.yaml` around lines 739 - 742: The
generated standard manifests contain the same validation rule and should be
regenerated together with manifests/standard.yaml.
In `@applyconfigurations/api/v1/clusterextensionspec.go`:
- Line 43: Update the documented XValidation rule in the cluster extension
specification to use standard CEL empty-string literals, replacing the
typographic quotation marks with two single quotes while preserving the existing
rule and message.
In `@docs/api-reference/olmv1-api-reference.md`:
- Line 361: Update the namespace field documentation in the API reference to
remove raw opcon directives and clearly publish separate standard and
experimental contracts: standard mode requires namespace, while experimental
mode permits omission, resolves and creates a managed namespace, and locks the
mode at creation. Ensure the corresponding validation text is unambiguous, then
regenerate the API reference using the existing crd-ref-docs generation target.
In `@docs/draft/concepts/managed-namespaces.md`:
- Around line 29-31: Update the managed-namespaces resource list to include only
namespaced operator resources, removing CRDs and webhook configurations. Add a
clarification that cluster-scoped resources remain after the managed Namespace
is deleted.
In `@internal/operator-controller/controllers/clusterobjectset_controller.go`:
- Around line 600-602: Update the Namespace branch in the collision error
formatting so it states that the Namespace already exists and cannot be adopted
when no conflicting owner is available; remove the claim that another controller
manages it, while preserving the existing behavior for other resource kinds.
In `@internal/operator-controller/rukpak/render/namespace.go`:
- Around line 49-54: The fallback construction in the default branch for
PackageName must always produce a namespace accepted by validateNamespaceName,
including dotted and overlong package names. Normalize disallowed characters,
enforce the namespace length limit, and preserve deterministic collision
resistance when truncating; retain the existing fallback behavior for valid
short names and add coverage for dotted and overlong package names.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Hash package names that require normalization.
foo.bar and foo-bar both sanitize to foo-bar, so both use foo-bar-system. The second managed installation then fails with a Namespace collision. Restrict the historical fast path to an unchanged package name, and use the hashed path whenever sanitization modifies it.
Proposed fix
- if base != "" && len(base)+1+len(suffix) <= maxNamespaceNameLength {
+ if packageName == base && base != "" && len(base)+1+len(suffix) <= maxNamespaceNameLength {
return base + "-" + suffix
}Update TestDefaultInstallNamespace with a foo.bar versus foo-bar collision test.

Description
When spec.namespace is omitted, operator-controller resolves a managed namespace from bundle metadata using the fallback chain: suggested-namespace-template > suggested-namespace > -system.
The managed namespace is included as a ClusterObjectSet object with collision protection. Pod Security Admission labels from the bundle's suggested-namespace-template annotation are applied to the managed namespace, enabling operators to declare their PSA requirements
