Docstring coverage is scoped to functions touched by this diff. Analyzed 0 functions across 1 files. Full details: Stable And Deterministic Test NamesExplanation PASS: The pull request adds a CI step and a deployment script. It does not add or change Ginkgo test titles. Searches of the changed files found no Full details: Test Structure And QualityExplanation PASS: The pull request does not add or modify Ginkgo test code. The cumulative diff contains one shell deployment script, YAML/JSON step metadata, OWNERS, and six CI configuration references.

The diff adds no Ginkgo e2e tests ( Full details: Single Node Openshift (Sno) Test CompatibilityExplanation PASS — The pull request adds only CI configuration, step-registry YAML/metadata/OWNERS, and a Bash deployment script. The changed paths contain no Ginkgo declarations ( Full details: Topology-Aware Scheduling CompatibilityExplanation The pull request adds one Deployment with Full details: Ote Binary Stdout ContractExplanation PASS: The pull-request diff has five changed paths and no changed Go files. It adds YAML, OWNERS, JSON metadata, and a Bash CI step. The Bash step uses echo and oc output, but it is a separate CI command step, not an OpenShift Tests Extension binary or suite setup. The six configuration additions only invoke this ref before the e2e test step. No stdout write in main(), init(), TestMain(), suite setup, or other OTE process-level code was introduced. Full details: Ipv6 And Disconnected Network Test CompatibilityExplanation The PR adds no Ginkgo declarations and contains no hardcoded IPv4 addresses. However, the new test setup requires a public registry image: the Deployment uses Resolution IPv6 and disconnected network compatibility notice: This test may contain IPv4 assumptions or external connectivity requirements that will fail in IPv6-only disconnected environments. Please verify your test works on IPv6 by running an additional CI job: For parallel tests: Full details: No-Weak-CryptoExplanation PASS. The pull request adds an NFS provisioner script, CI references, ownership metadata, and a StorageClass. The changed lines contain no MD5, SHA1, DES, 3DES, RC4, Blowfish, or ECB usage. The only digest reference is a SHA-256 image pin. No custom cryptography or non-constant-time secret/token comparison is present.

For example, use custom columns for timestamp, type, reason, and involved object name, and exclude event message, source, node names, IP addresses, and URLs. Keep the existing restricted pod output and review all failure diagnostics for the same exposure. ✨ Finishing Touches🧪 Generate unit tests (beta)

Remove privileged execution from the provisioner pod.
The namespace permits privileged pods. The ServiceAccount also receives the built-in
privilegedSCC. The init container then requestsprivileged: true.The pod cannot use the custom
nfs-sbr-provisionerSCC because that SCC disallows privileged containers. It will instead receive the unrestrictedprivilegedSCC. This permits broad host access through the mounted host paths.Use a scoped SCC with only the required capabilities and volume types. Remove the privileged SCC grant and the privileged init container. Set
allowPrivilegeEscalation: false, dropALLcapabilities, and add only required capabilities.Also applies to: 127-128, 197-198

Wait for NFS readiness, not Pod phase.
A Pod enters
Runningbefore the NFS service is ready for mount requests. The Deployment also has no readiness probe. This step can return successfully before a following SBR test creates its first claim.Add readiness and liveness probes that verify the required NFS endpoint. Wait for the Deployment to become ready before creating the StorageClass or returning from the step.

This config change adds the new medik8s-sbr-nfs-dynamic-provisioner ref to six test variants, but the PR includes no regenerated Prow job files under ci-operator/jobs/. The ci/prow/generated-config check will fail because it compares committed generated files against fresh output.
