Unless it is no more isolated, I would say.

Entanglement are just special superpositions, involving many “bodies”. Previews entanglement cannot disappear, but can be “traced out” and discarded FAPP. > Are prior entanglements completely obliterated, I don’t think that is possible (unless wave collapse is postulated). > or are they just obliterated FAPP, meaning that maximal entanglement is also > only FAPP? Yes, I would say it is local to the isolated system you are concerned with. Some people argue that if we are machine with a so low level of substitution that we need the exact quantum state of the brain, then, the whole universe needs to be duplicated, because a quantum Big Bang entangled all possible particles at the start. > ISTM that some remote trace of entanglement - a kind of micro-entanglement - > must remain? In principle, yes. I would say. In practice, we can’t recover them, it would be as hard as reversing the “Schroedinger equation” of the whole universe. That is even more difficult than resuscitating a Schroedinger cat, which is already technically unfeasible.
