 ### Fixes
 
+- Control UI/chat: keep live replies visible when a raw session alias such as `main` sends the chat turn but Gateway emits events under the canonical session key for the same run. Fixes #73716. Thanks @teebes.
 - TTS/Telegram: keep trusted local audio generated by the TTS tool queued for voice-note delivery even when the run-level built-in tool list omits the raw `tts` name. Fixes #74752. Thanks @Loveworld3033 and @andyliu.
 - TTS: require explicit user or config audio intent for the agent speech tool so dashboard chats stay text unless audio is requested. Fixes #69777. Thanks @alexandre-leng.
 - Plugins/config: keep bundled source-checkout plugins from being runtime-gated by install-only `minHostVersion` metadata, accept prerelease host floors, trim plugin-service startup failures to one log line, and avoid broad channel-runtime loading during base config parsing. Thanks @vincentkoc.
