"""The CLI must use the decision log the same way propagate() does.

The CLI streams the graph itself instead of calling propagate(), so memory steps
that lived only in propagate() never ran on the primary entry point: pending
decisions were not settled, the Portfolio Manager got no past context, and the
finished decision was not recorded. Both paths now build their initial state and
record their decision through the same graph methods.
