l would be constructed/programmed according to the KISS principle, and would NOT include "complicated programming."  This assumes that was the first use and only intended use of this particular Ter'angreal. I would agree, if we knew for sure that the Aes Sedai that ended up Rhuidean...somehow had the capability to create this kind of Ter'angreal...you would be right. I need to go back and read Rand's trip and see if we know for sure.  Along this route of thinking, I doubt she broke it. I think she unconsciously reprogrammed it, something it was built to be able to do.  If that is the case, then whatever it was reprogrammed to do involves what can be learned from "Blood and Bone." The "hardware" of the ter'angreal analyzes Blood (and Bone) to extract ancestral experiences. Whatever it might be reprogrammed to extract, it has to use the same "hardware" to do so.  You assume that it was only programmed to analyze Blood and Bone.
