Follow up: a clean and scuffed (with the green side of a new soong) bed, letting the printer set idle with the bed at 100c for an hour (evidently klipper will turn the bed off after 30 minutes), readjusting my x-offset (I balme the new build, but for whatever reason the nozzle wasn't as close as it used to be), and adding a brim = great success. I'll probably tinker some more to see if I can get rid of the brim, but I got it printed in ASA successfully.
