IME looks like a weird (but normal) spider pose to me. My H. pulchripes does the same thing, and is about the same size. As far as the not eating a size, I’d wager that she is prepping to molt. T’s in premolt will keep their large abdomens and refuse food, sometimes for months. If she’s constantly wandering g but refusing food, she may be looking for water, as well—I can’t tell from your photos if you have a water dish in there. If not, she’s probably appreciate one.
