Included review availability: Your plan includes up to 3 reviews per rolling hour; 1 remains after this review. 📝 WalkthroughWalkthroughThe Kubernetes ingestor now exposes a resource-filter extension point. Backend modules can register filters with resource and cluster context. The data provider applies all filters after built-in exclusions during full ingestion and delta updates. ChangesKubernetes resource filtering
Estimated code review effort: 3 (Moderate) | ~25 minutes Merge Risk: 🟡 Moderate · up to Custom resource filters may not consistently exclude resources: delta updates can reintroduce filtered resources, filter ordering can change eligibility behavior, and resources that later become excluded may remain in the catalog. Merge should wait until these correctness issues are fixed or explicitly accepted. Sequence Diagram(s)sequenceDiagram

Remove prior entities when an upsert becomes ineligible.
This test expects no mutation after a filter rejects an upsert. If the Deployment was eligible before this update, deltaUpdateInner returns without removing its existing catalog entities. The resource remains in the catalog until a later full sync.
Add a transition test that first ingests the resource, then updates it to fail the filter. Update delta handling to remove the resource's prior entities when eligibility changes to false.

🎯 Functional Correctness | 🟠 Major | 🏗️ Heavy lift
Run custom filters after the Crossplane and KRO checks.
Lines 230-232 invoke registered filters before lines 235-247 reject disabled Crossplane and KRO resources. A filter can therefore run for a resource that the plugin will not ingest.
Split the built-in eligibility checks from custom filter invocation. Invoke custom filters only after all existing provider checks pass. Apply the same order in KubernetesEntityProvider.deltaUpdateInner.

kubernetesIngestorExtensionPointwithaddResourceFilter. A filter receives the resource and its cluster name and returns false to exclude it. Multiple filters may be registered; all must pass. Filters run after the plugin's own checks, with no filter registered nothing changes.Summary by CodeRabbit
