The members concern CORS headers on the /v1/runs/{run_id}/events server-sent events endpoint of the API server. One is a bug report about cross-origin requests erroring, and three are pull requests proposing CORS changes; one of those also mentions flushing the stream head and reporting tool errors as tool.failed.
