LLM-42: take the fast path, then verify the computation
LLM-42 proposes verified speculation for deterministic inference, retaining a fast path while checking which tokens can be committed.

Before you press replay, list what will run again
LangGraph and Temporal show why replay needs a precise definition. Check the checkpoint, event history and external actions.
