During October 2025, Norrs contributed to the envoyproxy/envoy repository by implementing explicit gRPC error reporting for the rate limit quota (RLQS) filter. This work introduced a configuration-driven approach that allows explicit gRPC status codes and messages to be set for deny responses, enhancing error clarity and consistency for gRPC clients. Norrs used C++ and YAML to enforce precedence rules, ensuring that explicit gRPC statuses override HTTP-to-gRPC mappings, and updated related tests to validate the new behavior. Documentation and release notes were expanded to describe the new deny_response_settings options, reflecting a focused and well-scoped engineering effort.
