Agent Frameworks
LangChain, LlamaIndex, and Pydantic
- highAgent factory `_execute_model_async` uses non-streaming `ainvoke`, preventing `on_llm_new_token` callbacks
- highOpenAI computer-use tool calls are not executed as LangChain tool calls
- highRunnableSequence.astream leaks TCP socket FDs on client disconnect
- highContent block corruption when using type file
- highRootModel unions fail to deserialize Document/HumanMessage due to constructor TypeError
