 SimulationManager remains the orchestrator and event boundary. It owns
 simulation records, invokes the focused systems, stores selected actions and
 targets, and translates presentation callbacks into simulation transitions.
+It also publishes the latest `ActionSelectionResult` for presentation; the UI
+does not recompute decisions.
 Further decomposition should follow measured pressure rather than splitting it
 into managers for their own sake.
