El issue no menciona archivos, pruebas ni puntos de entrada. Empieza por aclarar los controles de Lambda solicitados y los requisitos para streams bidireccionales, con estado y de larga duración; darlo por terminado requeriría una forma explícitamente definida de compatibilidad con el streaming bidireccional.
