- Line 53: Update the FIPS filtering flow around filterFIPSCurvePreferences to
preserve Custom profile enforcement: when filtering removes every explicitly
configured curve, reject the profile or use an explicit documented FIPS-safe
fallback rather than leaving CurvePreferences empty and allowing Go defaults.

🟡 Minor · Unwrap informer tombstones before resetting the TLS configuration. · syncer.go:202-215
pkg/lib/apiserver/syncer.go:202-215
🎯 Functional Correctness | 🟡 Minor | ⚡ Quick winUnwrap informer tombstones before resetting the TLS configuration.
RegisterEventHandlerspasses APIServer informer deletions toHandleAPIServerDelete. The informer can pass acache.DeletedFinalStateUnknowntombstone. The current type assertion rejects that tombstone and returns beforeGetSecurityProfileConfig(nil). Later API-server TLS queries can retain the deleted profile'sCurvePreferencesinstead of using the Intermediate defaults.Suggested fix
func (w *Syncer) HandleAPIServerDelete(object interface{}) { + if tombstone, ok := object.(cache.DeletedFinalStateUnknown); ok { + object = tombstone.Obj + } + _, ok := object.(*apiconfigv1.APIServer)🤖 Prompt for AI Agents

olmapiserver.GetSecurityProfileConfig() is called by_applyClusterTLSProfileWithClients()_ which in turn is called only via applyClusterTLSProfile().
applyClusterTLSProfile() is guarded by if o.SecureServing.MinTLSVersion == "": so when --tls-min-version is set, packageserver never fetches the APIServer profile and leaves CurvePreferences empty, using Go’s default groups instead of the cluster allowlist.
This issue (getting olmapiserver.GetSecurityProfileConfig() in the call stack only when --tls-min-version is not set) predates this PR and could be addressed in a separate PR (if worth it).
