# NousResearch/hermes-agent · Photon zombie-stream probe GUID fix

## Open now

- Nothing open on GitHub.

A bug where the photon liveness probe used a non-GUID synthetic ID, preventing silent-inbound (zombie) stream detection from ever firing. The fix changes the probe message ID to a valid GUID format.
