run_counterfactual
Run an isolated alternate timeline without modifying the user’s live country. Event interventions automatically branch from the saved event checkpoint unless an explicit valid snapshotId is supplied, preventing already-realized damage from contaminating the experiment. Use normalized eventId values returned by read tools.
