    This is OpenAPI documentation for Reporter. The unified reporter binary
    serves the REST API (RUN_MODE=api) and/or the RabbitMQ report-generation
    worker (RUN_MODE=worker); RUN_MODE=all runs both in one process for local
    development. All REST endpoints documented here serve only when RUN_MODE=api
    or all (port :4005); the worker (port :4006) exposes health/readyz only.
