Module replay_cursor 

Replay cursor engine: reconstruct state from the event log without live side effects.

The replay loop is: Load checkpoint → Replay events → Inject recorded outputs → Reconstruct state. This engine holds only the event store, optional snapshot store, and reducer. It has no executor or step function, so live tool execution is hard-disabled during replay. Recorded action outputs (ActionSucceeded/ActionFailed) are already in the log and applied by the reducer.
