Predictive pacing locked at 0.9x after enabling real-time DNC check

Admin UI won’t apply a pacing multiplier above 0.9x the second real-time DNC checking flips on for the Q1 outreach list. Running the 2024-12-18 release on US-East. The save button just spins and returns a 422 UNPROCESSABLE_ENTITY via the console. Abandonment rate is sitting pretty at 0.8%, so the queue’s technically healthy, but seats are burning faster than callers. Logs show OUTBOUND_PREDICTIVE_THRESHOLD_VIOLATION even though the threshold is set to 10%.
