- copilotkit/a2ui.py: load_schema(), surface_update(), data_model_update(), begin_rendering(), render() — canonical SDK for building A2UI operations - A2UIMessageRenderer reads a2ui_operations (with operations fallback) - local-install script now includes editable pip install of Python SDK - search_flights uses `from copilotkit import a2ui` pattern Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
