# NousResearch/hermes-agent · Superseded SSE streams interleaving into one transcript turn

## Open now

- Nothing open on GitHub.

Members describe a retry superseding a still-live SSE stream without aborting it, causing two streams to interleave tokens in one transcript turn. Two members are pull requests (one title appears twice) proposing to fence superseded streams out of the delta sink with a single writer.

## TL;DR
