 "title": "Dwell time controls oscillation in a fallback ladder and hysteresis does nothing, because the rungs are too far apart for a band to bind",
 "symptom": "With a disturbance parked exactly on the liveness threshold, dwell time is monotonic and powerful: 447 switches per minute at dwell 0 falling to 69 at dwell 2000 ms, a 6.5-fold reduction, landing at the lowest measured peak buffer occupancy. Hysteresis over the same setup did nothing interpretable \u2014 swept at 0, 10, 20, 40 and 80 percent the switch counts were 28, 26, 6, 18 and 28, with no monotonic trend and the minimum not separable from run-to-run noise.",
