PersistentVolumeClaim and rejectPVCs so that when rejectPVCs is false it emits a
structured warning through the request logger before continuing. Include the
workload and volume identifiers in the warning, use the request-handling warn
convention, and preserve the existing rejection error behavior when rejectPVCs
is true.

PersistentVolumeClaims are not officially supported in NVCF helm charts but were previously allowed through validation. The DGXC SBOM rollout removes the default storage class from clusters, causing charts with PVCs to fail at deploy time with opaque errors. This adds a reject-pvcs config flag (default: false) to RevalConfig and HandlerOptions. When false, PVC resources and volume references produce a warning log. When true, validation fails with a clear error message. SRE can enable enforcement by setting reject-pvcs: true in the service config after all clusters have been migrated.
- Thread logger into validateVolumes so PVC volume refs emit a structured warning (with volume name) when rejectPVCs=false - Add config-wiring tests for reject-pvcs config key, REVAL_REJECT_PVCS env var, and default-false behavior
- Add BindEnv for reject-pvcs so REVAL_REJECT_PVCS env var propagates through Unmarshal reliably - Include pvc name and namespace in standalone PVC warn-only log

There is a much simpler way to do this in checkTypes
Simplifies the PVC handling by placing it in checkTypes where type validation already happens, rather than duplicating a special case in validateReleaseObjects.

Why
PersistentVolumeClaims are not officially supported in NVCF helm charts but were previously passing validation silently. The DGXC SBOM rollout removes the default storage class from clusters, which will cause customer functions with PVCs to fail at deploy time with opaque errors rather than a clear validation message.
Adding early validation at helm chart ingest time gives customers a clear, actionable error instead of an opaque deployment failure downstream.
What changed
RejectPVCs booltoHandlerOptionsinreval/run.gofalse(default): PVC objects and PVC volume references log a warning and pass validation — no behavior change for existing deploymentstrue: validation fails with"PersistentVolumeClaims are not supported in NVCF helm charts. Please remove all PVC definitions before deploying."RejectPVCs boolwithmapstructure:"reject-pvcs"toRevalConfiginpkg/reval/config/config.gocfg.RejectPVCsintoHandlerOptionsincmd/reval/cli/server.goTest_validateVolumes_RejectPVCscovering bothtrueandfalsecasesCustomer Release Notes
Not customer visible — this is a service-side validation gate. Customers will see a clear error message when enforcement is enabled rather than an opaque deployment failure.
Plan Summary
Not applicable.
Usage
Enable enforcement via environment variable:
