Worked on the kubernetes/api repository to clarify documentation regarding the ResizePolicy constraint for ephemeral containers. Updated proto comments, Go type definitions, and Swagger documentation to explicitly state that ResizePolicy does not apply to ephemeral containers, ensuring that API documentation accurately reflects actual system behavior. This documentation-focused effort, using Go and protobuf, improved consistency between API semantics and type definitions, reducing the risk of client-side misconfigurations and support issues. No changes were made to core functionality, preserving runtime stability while enhancing developer experience and API governance. All updates were traceable through a dedicated commit for future audit and reference.
