Conversation
Add four new validations to the MCPRemoteProxy controller, each surfacing errors via Kubernetes Events and Status Conditions: - Remote URL format validation (scheme and host) - JWKS URL scheme validation (must use HTTPS) - Cedar authorization policy syntax validation - ConfigMap/Secret reference existence checks Includes unit tests for all validation functions, reconciler condition tests, and integration tests for both conditions and event emission.

A few nits from going through the validation additions. Nothing blocking — the overall structure is solid.
- Add failValidation helper to consolidate the repeated
recordValidationEvent → setConfigurationInvalidCondition → return
pattern across validateSpec
- Remove redundant early empty-URL check; ValidateRemoteURL already
handles empty strings and now goes through failValidation
- Fix external auth config block to emit events and set the
ConfigurationValid condition on failure (was silently missing both)
- Replace fmt.Errorf("%s", msg) with errors.New(msg) where no wrapping
is needed
- Sanitize non-NotFound K8s API errors so internal details (API server
URLs, RBAC info) are logged but not exposed in status conditions

The RemoteURL field has a kubebuilder Pattern validation (^https?://) that rejects non-HTTP schemes at the API server level. Update the integration test to verify the CRD rejects the resource at creation time rather than waiting for the controller to set a condition. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Summary
Extends #4024 with the four remaining MCPRemoteProxy configuration validations, each surfacing errors via Kubernetes Events and Status Conditions:
ftp://, empty host)All validations follow the foundation pattern from #4024: fail-fast in
validateSpec(), setConfigurationValid=Falsecondition with a specific reason, emit a Warning event, and move the proxy toFailedphase.No network calls are made — URL validations are format/scheme checks only; ConfigMap/Secret checks are in-cluster reads.
Closes #2289
