 ### Fixed
 
+- Fixed first user messages rendering without spacing after existing notices such as compaction summaries or status messages ([#3613](https://github.com/badlogic/pi-mono/issues/3613))
 - Fixed the handoff extension example to use the replacement-session context after creating a new session, avoiding stale `ctx` errors when it installs the generated prompt ([#3606](https://github.com/badlogic/pi-mono/issues/3606))
 - Fixed session replacement and `/quit` teardown ordering to run host-owned extension UI cleanup synchronously after `session_shutdown` handlers complete but before invalidating the old extension context, preventing stale extension UI from rendering against a disposed session.
 - Fixed crash on `/quit` when an extension registers a custom footer whose `render()` accesses `ctx`, by tearing down extension-provided UI before invalidating the extension runner during shutdown ([#3595](https://github.com/badlogic/pi-mono/issues/3595))
