I've come to the conclusion that Alicia was just a random vine that the original vendor mistook for
Diplopterys cabrerana based on a superficial similarity of the seeds. Ethnobotanical vendors continue to offer it I think mostly just because people will buy it. I have seen reports where people claim that fresh leaf is active, but there doesn't seem to be any consistency, with most reports sounding like placebo. My own experience with it has been underwhelming to the point where I abandoned working with it.
It doesn't occur in any of the ethnobotanical litereture, and the GC/MS analysis you mentioned was ambiguous at best.
I used to maintain a live specimen in my collection as a curiosity and as a hedge against the day when someone might actually discover some activity in the plant. I forgot to bring it in during the last freeze, and honestly don't know if it made it because I haven't looked at it since then.
I'll take that as a sign that I don't care any more.
I already asked Alice.
