Is there ANYTHING I could be doing wrong with the Taylor test that could be giving me a false positive for CC?
Not likely. If you get a pink color, the DPD is working.

I haven't re-read the whole thread (forgive me Janet, Dave, Lisa!) but your levels are completely consistent with a pool that experienced bacterial metabolysis of CYA to ammonia or urea. There is absolutely nothing going on with your pool that is surprising or unexpected to us.
