We know a lot about the timing, materials, and physical conditions needed to make chondrules and CAIs, and people have used these to make models for their formation. But many of these constraints are under scrutiny right now, and some pretty basic things are still controversial. What this means is... ok, we don't know cr*p. But progress is being made.
