PartEndEvent was added in pydantic-ai v1.9.0 (PR #2923) as part of the Vercel AI Data Stream Protocol support. This event signals when a part is complete during streaming. Changes: - Import PartEndEvent from pydantic_ai.messages - Add handler in _process_pydantic_event to acknowledge PartEndEvent without emitting a Marvin event (completion is handled via other events like FunctionToolCallEvent and FinalResultEvent) - Update pydantic-ai dependency from >=0.7.2 to >=1.9.0 to ensure PartEndEvent is available This fixes the "Unknown event type: PartEndEvent" warnings that started appearing after pydantic-ai was updated. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <[email protected]>
