Okay so the tldr; of this could be : In a nondeterministic universe, effects imply at least one cause, but a cause does not imply an effect, therefore a causal model implies some kind of time like asymmetry. Correct?

So then it seems to me you can make the obvious extension into a quantum universe by subsituting probability mass for amplitudes. So that in our quantum, deterministic universe, the asymmetry comes from the way amplitude spreads down everett branches, and our confinement to a single one. A dead cat in schroedinger's box now implies a live one a certain time in the past, a live one now does not necessitate a dead one at any given time in the past.
