- Base checkpoint: V397.
- Existing exercise/profile: figure-fours / warmup_figure_four_walk_ik_v1.
- New user clip installed at the canonical Figure Four media path.
- V387 baked geometry and smooth grip transitions preserved exactly.
- Measured source relationship: V387 old_time -> V398 new_time = old_time - 0.166667 s over the overlapping motion; new source includes a longer post-action tail.
- Phase timing remapped to the new 6.816667 s clip; tail remains neutral/travel reset hold.
- No new IK profile. No new solver. 0 live solver calls.
