-4 s rollout from run `2026-10-07_15-14-19`, training step 20000, held command 0.1 m/s forward. The gate read NO-WALK: speed 1.27 m/s with stance-switch rate 0.0 Hz and right-foot duty 0.0. It moves fast without alternating feet.
+8 s rollout from run `2026-10-18_21-53-55`, training step 94,208,000 (checkpoint `step_94208000.pt`), held command 0.3 m/s forward. The clip stays upright (torso 0.263-0.286 m) but advances only about 0.03 m, so it still does not walk.
