Explanation
The title "docs(nvcre): record release ownership of cluster-scoped objects" matches the main change: a new documentation subsection on how cluster-scoped LogProfile, ClusterRole/ClusterRoleBinding, and CRD objects are owned and handled across install, upgrade, second release, uninstall, and reinstall. It is specific and follows a conventional commit style. The title does not mention the Trainer-version sentence or the Helm 3 versus Helm 4 edit behavior, but those are secondary details.

Explanation
The description states the documented subject (cluster-scoped objects, release ownership, CRDs, LogProfile edits on upgrade, and the cre-training-goodput run against Kubeflow Trainer 2.2.0). It also gives the files touched, the live EKS and Kind observations, the stated exclusions, the checks run, and the risk level. It is directly related to the changeset.

| The chart creates cluster-scoped objects with fixed names: four `LogProfile` resources (`megatron-bridge`, `megatron-training`, `nccl-bandwidth`, `nccl-loopback`), 24 `ClusterRole`s, and two `ClusterRoleBinding`s. `fullnameOverride: nvcre` in the shipped values is what fixes the RBAC names, and `LogProfile` names are fixed by the chart regardless. Every one carries Helm ownership annotations for the release `nvcre` and none carries `helm.sh/resource-policy`. Because of that, a Helm release owns them for its whole lifetime: | ||

Limit the upgrade claim to the tested upgrade.
The bullet says upgrades keep these resources in place, but the supplied evidence covers one revision 1-to-2 upgrade. Qualify the statement so readers do not treat it as a guarantee across chart revisions.
The PR objective also describes one observed upgrade.
Suggested wording
-- **Upgrade** keeps them in place. A revision 1 to revision 2 upgrade left the same four `LogProfile`s, 26 RBAC objects, and seven CRDs.
+- **Upgrade:** In the observed revision 1-to-2 upgrade, the same four `LogProfile`s, 26 RBAC objects, and seven CRDs remained in place.📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

| - **Upgrade** keeps them in place. A revision 1 to revision 2 upgrade left the same four `LogProfile`s, 26 RBAC objects, and seven CRDs. | ||
| - **A second release** with the shipped values cannot coexist, even in another namespace. Installing it fails before creating anything, with Helm reporting that the first cluster-scoped object it reaches (`ClusterRole nvcre-bandwidthmeasurement-admin-role`) already belongs to release `nvcre`. The `LogProfile` names carry no release prefix, so changing `fullnameOverride` to rename the RBAC objects would leave those names to collide; that case was not tested. | ||
| - **Uninstall** deletes the `LogProfile`s and all RBAC objects, and leaves the seven CRDs behind, as Helm does for anything in a chart's `crds/` directory. The `nccl-bandwidth` `LogProfile` is what the NCCL check's parse rules come from, so a cluster that has uninstalled the release has the CRDs but no profile. | ||
| - **Editing a shipped `LogProfile`** changes what the next upgrade does, and the answer depends on the Helm client. The v0.7.0 chart adds a `networkTransport` pattern to `nccl-bandwidth`, which the NCCL check's transport assertion relies on. With Helm 3.17.1, an edit to `spec.patterns.bandwidthResult.example` survived a v0.6.0 to v0.7.0 upgrade and the new pattern was still added. With Helm 4.3.0, which applies server-side, the same upgrade failed with `UPGRADE FAILED: conflict occurred while applying object /nccl-bandwidth` naming the editing field manager, and the profile was left without `networkTransport`. Re-running with `helm upgrade --force-conflicts` succeeded, added `networkTransport`, and reverted the edit to the chart's value. The `LogProfile` schema is closed: a pattern name the chart does not define is rejected at edit time with `unknown field`, so only the fields the chart sets can be edited. |

Align the PR scope with the documented test claims.
The PR description says that edited LogProfile persistence and other deployers were not tested. However, the documentation states that the Helm 3/Helm 4 LogProfile upgrade test and a separate Helmfile CRD-upgrade test were performed. If these runs occurred, update the PR description. Otherwise, remove or qualify the claims.

Mark this as an out-of-band run, not a registry qualification result.
The registry path has no cre-training-goodput qualification for EKS/H100 and skips before creating a Certification. Because this sentence reports the registry’s Trainer and a passing constraint, readers can interpret it as a qualified result. State the run scope explicitly.

Qualify the second-release result as a dry run.
The supplied observation is a server-side dry run, but this bullet says that installing a second release fails before creating anything. A dry run does not establish the resource-creation behavior of a real install. Rewrite it as “A server-side dry run of a second release...” or document an actual install result.
