Greptile Summary

This PR updates the v26.4.x OCP bundle to 26.4.1-rc.2. The main changes are:

• Bundle channel metadata is reordered to stable,v26.4.
• The CSV name, version, timestamp, and default example versions are updated.
• Operator, init container, plugin, and driver image references are updated to new digests.
• Most image repositories move from production nvcr.io/nvidia/... paths to nvcr.io/nvstaging/mellanox/... paths.
• Additional doca-driver-* related images are added for the new DOCA driver version.

Confidence Score: 4/5

The bundle can expose an RC staging image set through the stable/default channel.

• Stable subscriptions can resolve this CSV if it is published into a shared catalog.
• The operator and most related images now pull from nvcr.io/nvstaging/mellanox.
• Production and disconnected clusters may not have credentials or mirror rules for those staging repositories.

bundle/metadata/annotations.yaml; bundle/manifests/nvidia-network-operator.clusterserviceversion.yaml

Security Review

The bundle crosses a release boundary by combining stable/default channel metadata with staging registry image references. A production or disconnected catalog can select the RC CSV and then fail to pull images or mirror staging artifacts.

Important Files Changed

Filename	Overview
bundle.Dockerfile	Reorders the bundle channels label to stable,v26.4; the order itself is unlikely to affect OLM selection.
bundle/metadata/annotations.yaml	Keeps stable as the default channel for an RC bundle, which can expose the RC to stable subscriptions.
bundle/manifests/nvidia-network-operator.clusterserviceversion.yaml	Updates the CSV to 26.4.1-rc.2 and changes most runtime and related images to nvstaging repositories.

Stable Channel Carries RC

This bundle advertises 26.4.1-rc.2 on the stable channel and keeps stable as the default. If the bundle is added to a catalog used by stable subscriptions, OLM can select this release-candidate CSV and deploy the staging image set instead of a production build.

Note: If this suggestion doesn't match your team's coding style, reply to this and let me know. I'll remember it for next time!

Staging Registry Pulls Production

The deployed operator image now points at nvcr.io/nvstaging/mellanox, and the CSV also uses nvstaging for the init image and most related images. When this bundle is installed or mirrored from a production catalog, clusters that only have production NVIDIA registry access can hit image pull or disconnected mirroring failures before the operator becomes ready.
