The lingering doubles were a real bug, not a taste problem: racketAI's !incoming return kept the last chase's vx/vz on the body, so the speed ghosts trailed a zombie that had already stopped. The velocity dies with the chase now (tested). The look is halved with it: ghost alphas 0.22/0.10 -> 0.11/0.05, trailK 0.05 -> 0.035 — a hint of speed in the corner of the eye, never a second body.
