Conflicts is every OTHER assertion knowable at AsOf, strongest first. They are not all disagreements: one that repeats the winner's value ranks below it and is listed here too.
Truncated says this pair holds more assertions than one read returns, so the winner was decided from the most recent ceiling-full of them. It is reported because a provenance plane that trims silently is a plane that answers confidently and wrongly; narrow the question with as_of to see what it dropped.
