The dated record for the jerky-at-2000-mm/min thread: what was wrong, what changed, and what the bench measured. Keeps the two results that matter. The A/B that isolated the cause - two acceptance runs 90 s apart on one image, camera the only variable, PASS with a nice-5 CPU hog and FAIL with the camera streaming - and the LB-GF-OG-FM job re-run on the fix with the video live, clean at min margin 3.1 ms of 10. Also records that max behind is not the instrument: it reads 0.0 ms through a passing run whose real margin fell to 4.9 ms, because the producer never falls behind its own wakeup epoch. Only the measured min margin shows the condition.
