Background

The TuiMaterializer is the bridge between the A2A event queue and the TUI conversation view. It consumes A2A plan execution events (text chunks, tool calls, thought blocks, errors) and renders them as conversation widgets in real-time, providing the live streaming experience that makes the TUI feel responsive.

Acceptance Criteria

  • TuiMaterializer class implemented consuming A2A event queue
  • Text chunk events rendered as streaming text in conversation view
  • Tool call events rendered with tool name and arguments
  • Error events rendered with error message and stack trace (collapsed)
  • Throbber animation active during actor execution
  • Test coverage >= 97%
