The logic analyzer finally arrived, so I ran the one test episode 19 promised would settle it. I validated the instrument, watched both channels sit dead flat through spin after spin, and had my finger on the button to order the replacement. The sensor was fine. I'd wired its power backwards — and it turns out I'd had the pinout backwards for two weeks.
