Q14 in the CBA FAQ notes that the full season salaries of players traded away mid-season are not counted as part of team salary.
Thanks. I guess in my head I couldn't decide if that meant that the entire season came off the books, or merely that not all of the season counted (i.e. por-ration.) Reading it in isolation makes it sound more clear that the entire season comes off (although doing so makes the "hard cap" seem less hard, since we gained more space than we would have if traded salaries were all pro-rated, and yet any other players we sign this year will count at the pro-rated level. I think.)
