🟡 Changes recommended

The v7 parser types are incompatible with Kubernetes managedfields APIs still typed against v6, so the project no longer compiles.

Once you've addressed the issues Copilot identified, you can request another Copilot review.

Pull request overview

Updates sigs.k8s.io/structured-merge-diff from v6.4.2 to v7.0.0 and switches the generated parser import.

Changes:

• Adds the v7 module and checksums.
• Retains v6 transitively.
• Updates generated apply-configuration parsing.

Critical finding: the v7 parser is incompatible with Kubernetes APIs still typed against v6, causing compilation failure.

File summaries

🔵 Needs a closer look

The generated parser change causes type incompatibilities with the current managedfields API and will fail to compile.

applyconfigurations/internal/internal.go:9

• This generated package now exposes *structured-merge-diff/v7/typed.Parser, but the k8s.io/apimachinery v0.37.0 managedfields API is built against the v6 typed package (the retained v6 indirect requirement is evidence of that dependency). As a result, calls such as managedfields.NewSchemeTypeConverter(scheme, internal.Parser()) and managedfields.ExtractInto(..., internal.Parser().Type(...), ...) will fail to compile because the v7 types are not assignable to the v6 types. Keep the generated code on v6, or upgrade the Kubernetes dependency set to a release whose managedfields API uses v7 before switching this import.
