No LLM provider, API key, checkpointer, or Lockstep is needed. The reproduction uses the real YAML loader/compiler and an ordinary state-only Python tool. It does not call private wrappers or monkeypatch them. ## Summary Adding `timeout: 2` to an otherwise working Python node makes `langgraph.config.get_config()` fail with: ```text RuntimeError: Called get_config outside of ## Literal error text ``` timeout drops LangGraph runnable context ``` ## Environment GitHub issue sheikkinen/yamlgraph #708 ## Trigger / context Follow-up to [#474](https://github.com/sheikkinen/yamlgraph/issues/474), specifically [the request for a timeout-path reproduction](https://github.com/sheikkinen/yamlgraph/issues/474#issuecomment-5800222508). ## Versions Reproduced with Python 3.12.14, `yamlgraph==0.6.0`, `langgraph==1.2.10`, `langchain-core==1.5.6`. No LLM provider, API key, checkpointer, or Lockstep is needed. The reproduction uses the real YAML loader/compiler and an ordinary state-only Python tool. It does not call private wrappers or monkeypatch them. ## Summary Adding `timeout: 2` to an otherwise working Python node makes `langgraph.config.get_config()` fail with: ```text RuntimeError: Called get_config outside of a runnable context ``` The caller supplies `configurable.sentinel` to `app.invoke`. Without a timeout, the Python tool reads it successfully. With the timeout, the node runs on a new `ThreadPoolExecutor` thread whose context does not contain the runnable config. This is distinct from the subgraph defects fixed in #673. ## Minimal reproduction Save these three files in one directory. `repro_tools.py`: ```python from langgraph.config import get_config def observe(_state): return {"obse ## Source evidence - https://github.com/sheikkinen/yamlgraph/issues/708 (2026-09-26T10:19:56Z) — #708 ## Freshness - classification: FRESH_7D - retrieved_at: 2026-10-02T09:46:06.809152Z - scout_id: C7ceb70ae70 ## Scout notes This Problem was published by the KFA Fresh Friction Scout from public sources.
