Improvements
Updated how the controller caches cluster object data when the Boxcutter runtime is enabled. Object sets are cached when they include an owner label, and deployments retain annotation filtering; deployments without that label have their specification and status excluded from the cache.
The controller continues to use the existing default cache settings when the Boxcutter runtime is not enabled.
Reduce retained Boxcutter cache data while preserving objects needed for
revision discovery, ownership checks, and storage migration.
Co-Authored-By: GPT-6 Luna <noreply@github.com>
The manager cache configuration moved into newCacheOptions. Default cache settings remain, and Boxcutter runtime enables owner-label filtering for object sets and spec/status clearing for unlabeled deployments.
Changes: Manager Cache Configuration

Summary
Build and apply cache options cmd/operator-controller/main.go
newCacheOptions defines default cache settings and adds Boxcutter-specific caching for ClusterObjectSet and ClusterObjectDeployment. Unlabeled deployments have their spec and status cleared, and annotation stripping applies to all deployments. run calls the helper and returns configuration errors with a configuring manager cache prefix. The inline RBAC cache entries were removed.
Migration can miss existing revisions, and fallback status can reflect an unrelated deployment. Resolve these issues before merging.

- Around line 578-587: Update the cache configuration for ClusterObjectSet in
the options setup so its selector retains revisions regardless of owner labels;
use an unrestricted selector so ListForGroup can find unlabeled revisions during
storage migration. Leave the ClusterObjectDeployment selector unchanged.
- Around line 589-600: In the bundle-unavailable branch that accepts an existing
ClusterObjectDeployment, validate ownership before returning success: require
its OwnerKind label to identify a ClusterExtension and its OwnerName label to
match the current extension name. Otherwise return the existing “catalog content
unavailable and no deployment installed” error; do not use an uncached status
read as a substitute.

Retain unlabeled ClusterObjectSet revisions in the cache.
The storage migrator must treat an existing revision as present regardless of owner metadata. The new cache selector hides unlabeled revisions before ListForGroup reads them. Migration can therefore re-enter Helm migration and create a duplicate revision.

Require ownership before accepting the fallback COD.
The new cache makes every ClusterObjectDeployment visible, including an unrelated object with the same name as the ClusterExtension. The bundle-unavailable branch accepts that object from a name-only Get and returns success without checking ownership. Status reflection then reads the transform-cleared spec and status.
Require the COD to belong to the current extension before returning success. An uncached status read would expose the unowned object’s data without fixing this ownership boundary.
