consilium: A conclusion made with consideration, a determination, resolution, measure, plan, purpose, intention
But the Catechism doesn't say a Muslim has to convert
Because formal conversion may or may not happen. We believe in sovereignty of God, who, in His mercy can act in non-ritualistic ways.
Ok, how can that apply to (our notion) of God? At what "time" did God make that "conclusion" if he, by definition, knew it from all eternity? God, by definition, exists and works outside of time. God, by necessity, simply acts in "eternal present," as "in the beginning God said "Let there be light!' And there was light."

So what the catechism is really saying is that, by virtue of their Abrahamic faith, the Muslims are also "included in the plan of salvation" which really means that some of them may come to accept Christ and die "Catholic."
That's just a roundabout, politically correct way of saying "there is no salvation outside the Church," isn't it? Like I said, why can't the Catholic Church just cut through the fluff and either state openly what it is saying sub rosa, or just say "We believe that you can be saved if you are Catholic, but God is not limited to choose other options at his disposal which are not revealed to us"?
