    "key_changes": [
      "Wired sound triggers into ChatNotifier for sendMessage (on success)",
      "Added sound trigger for incoming messages in _handleMessageCreated (active channel)",
      "Added sound trigger for background channel messages in _handleBackgroundEvent",
      "All sound triggers respect isSoundEnabled preference",
      "All sound triggers check sender is not current user (no sound for own messages)",
      "Sound playback is non-blocking using catchError pattern",
      "Added PopupMenuButton to ChatScreen AppBar with sound toggle",
      "Sound toggle shows volume icon and switch control",
      "Fixed user ID detection to use currentUserProvider (AuthUser.id)",
      "Removed unnecessary imports"

  "concerns": [
    "No unit tests written for sound feedback (sound is nice-to-have feature)",
    "Sound service already has error handling, additional catchError is defensive",
    "PopupMenuButton uses ref.invalidate to trigger rebuild after preference change",
