The cohost sounded jittery on the 2026-11-03 show. v1 skipped ahead on an underrun and kept playing from an empty buffer, so after the first hiccup every later wobble was another glitch. It also never corrected a slow guest clock: ~12 glitches/min in simulation at 30 ppm slow. - Underrun: hold the sequence position and refill to a larger target - Drift correction both ways (drop/insert a frame in quiet moments), quiet judged relative to the guest's own noise floor - 80 ms start, 300 ms max, relaxes after 2 calm minutes - Log 'rx 1m:' stats, the selected route, and call totals - Ping the guest websocket every 25 s (the proxy closed it every 90 s) - Simulation kept in test/jb_sim_test.go.txt Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
