Line 342 combines the valid empty-option case and the invalid reader-option case in one test. Define these as separate table entries so each scenario has an independent result.

Reject the NVMesh provider in the non-NVMesh branch.
nonNVMeshDriver does not exclude provider: nvmesh. A different provisioner key can therefore declare the NVMesh provider and use non-NVMesh transition rules. Reject nvmesh in this branch.

Customer Summary
Publishes a versioned NVCA storage capability catalog for model-cache configuration. It does not enable a new storage provider or change runtime backend selection.
TL;DR
ConfigMap/nvcf-storage-capabilitieswith both NVCA Operator charts.This PR provides the public contract, loader, validation, tests, and design document. Stacked PR #1357 consumes the catalog at runtime.
Additional Details
The catalog entry shape is:
Allowed transition values are:
regularModelCachedisabled,roxReadOnly,rwxReadOnlyhelmModelCachedisabled,roxReadOnlyThe shipped NVMesh entry uses
roxReadOnlyfor both workflows and requiresro,norecovery, andnouuidon reader PVs. TherwxReadOnlystrategy is regular-cache only, requiresReadWriteMany, and requires an emptyreaderMountOptionsarray because it does not create or rewrite a reader PV.The shipped catalog records:
roxReadOnlyfor regular and Helm cachedisableddisableddisabledAn access mode or empty mount-option list does not qualify or enable a provider. A read-only Pod mount of an RWX claim is not ROX evidence.
The JSON Schema validates structure, required fields, closed transition values, provider restrictions, workflow restrictions, known mount-option conflicts, and source/release chart parity. The strict Go loader also rejects unknown fields, blank or duplicate values, and semantic mount-option conflicts.
Runtime reconciliation does not consume the catalog in this PR. Editing the ConfigMap cannot enable a provider until #1357 is released.
