The stride capture regressed after the 0.2.1 rig change, and the cause was the clip, not the harness: the walk cycle was authored on a sine, zero at both the start and the middle of the cycle - the two frames where the legs pass together. The probe showed identical hip rotations at frames 0 and 15 while 7 and 22 carried the stride.

The cycle now starts at maximum stride (cosine). Length, amplitudes and keys are unchanged; only the phase moved. demo-third-person-walk returns as shot 8 and shows a genuine stride. 8/8 shots verify.

The stride shot regressed twice for two different reasons, and only the second was
the clip. The walk cycle was authored on a sine, which is zero at both the start and
the middle of the cycle - exactly the two frames where the legs pass together - so a
deterministic capture at any phase near those frames read as a still. The probe
proved it: frames 0 and 15 carried identical hip rotations while 7 and 22 were the
stride.

The cycle now starts at maximum stride (cosine). Length, amplitudes, keys and loop
are unchanged; only the phase moved. demo-third-person-walk is back as shot 8 and
shows a genuine stride with the curled hands from 0.2.1.

8/8 shots verify.
