Worked on the istio/api repository to enhance the accuracy and clarity of documentation related to Envoy internal address configuration. Focused on aligning code comments with actual system behavior, a targeted correction was made to eliminate a misleading typo that previously risked misconfiguration for developers integrating Envoy with Istio. This update improved the maintainability of the codebase and provided clearer guidance for users. The work involved careful review and editing of Go and ProtoBuf documentation, emphasizing networking concepts and best practices. By refining both comments and documentation, the contribution supported better developer understanding and reduced potential integration errors in future deployments.
