CLAIM 9 / LangGraph
not as labeled
Observed
Source-reviewed: reported behavior diverges from the documented semantics — both concurrent requests are processed together and return merged combined tool calls (e.g. weather lookups for two cities in one response) rather than the prior run halting with its partial output preserved in isolation (langchain-ai/docs#474, opened 2025-09-01, open and re-verified 2026-06-11).
