Included review availability: Your plan provides up to 12 included reviews per hour; 11 remain after this review. 📝 WalkthroughWalkthroughThe change adds a versioned NVCF storage capability catalog, publishes it through both Helm charts, adds strict NVCA loading and validation, and extends Go and Helm checks for schema, content, parity, and rendering failures. ChangesStorage capability catalog
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to The catalog is installed and validated, but the published schema can accept provider strategies or whitespace values that the operator later rejects, while new lint output violates the repository's ASCII-only rule. Merge readiness is moderate until these issues are corrected or explicitly accepted. Sequence Diagram(s)sequenceDiagram

- Around line 151-152: Wrap the long qualification condition and related error
format strings in the storage capability validation logic, including the
corresponding block around the later lines, so every line stays within 120
characters. Preserve the existing validation behavior and run standard Go
formatting.
In `@src/compute-plane-services/nvca/scripts/lint_helm.sh`:
- Line 136: Replace the non-ASCII U+2713 checkmark in the status messages at the
three affected echo statements with an ASCII marker such as “OK”, preserving the
existing message text and validation behavior.

- Around line 234-236: Update the current public NVCA compatibility-path
description to include the nvcf-miniservice-sc marker as a sharedfs selection
after nvcf-sc-30 and before HelmSharedStorage, which remains the Samba fallback;
keep the target nvcf-sc provider-selection and transition behavior unchanged.
- Line 9: Update the NVCA Operator chart statement to say it installs the
storage catalog and packages the JSON Schema, distinguishing the rendered
nvcf-storage-capabilities ConfigMap from the packaged
nvcf-storage-capabilities-v1alpha1.schema.json file.

TL;DR
Publish a small, versioned NVCA storage catalog with both NVCA Operator charts. Each exact CSI provisioner records only:
NVMesh uses transition
nvmeshfor both workflows. Weka, OCI FSS, and OCI Lustre remaindisabled. Container cache is outside NVCA and is not represented.This PR installs and validates the catalog. It does not wire the catalog into runtime selection.
Configuration contract
The chart installs
ConfigMap/nvcf-storage-capabilitiesin the Helm release namespace and packages its JSON Schema:disabledmeans the workflow is disabled; a driver may still list qualified access modes. The catalog deliberately excludes expansion, snapshots, clones, topology, container cache, and other general CSI capabilities.Managed deployment configuration renders one provider as stable
StorageClass/nvcf-scwithRetain. Deployment tooling owns CSI parameters; NVCA owns model-cache transitions.The current catalog records:
nvmesh;A read-only Pod mount of an RWX claim is not ROX evidence.
Runtime boundary
Editing this ConfigMap cannot enable a provider today because reconciliation does not load it. Runtime work remains in #1326 and the included SDD. The target design:
