Hello,
SO She is dead. It wilted for a few days. Yesterday I grabbed it and kinda pulled it one direction. A healthy plant would have bent a bit, but the Thai just leaned over, like it had no roots attached. I gave a little tug and it practically came right out of the ground. I was very light and easy to pick up.
I'm not to bothered by it anymore. I knew it was doing poorly for a few weeks, and I have a few other girls, so... Live and learn.
I still don't know what happened. The root system was hard to examine, because it seemed like there was nothing there... I was watering it a goodly amount every couple days. probably 8-16 gallons at a time. I wonder if I was over-watering.. I have read about Vermiculum wilt a bit, but I can't really say whether or not that is what happened.
I definitely have less than ideal drainage, and hope to fix that by next summer.

Hoge stem came out easy and almost no roota attached:
