# V411 Lateral Lunges — correct start side + centered display

Base: V410.

Preserved:
- V410 planted-foot authority and biomechanical travel.
- V409 foot/ankle orientation.
- V408 lateral-lunge geometry, arms, depth and 6.6 s timing.
- No new IK profile; no new solver; 0 live solver calls.

Changes:
1. Phase rotated by 0.5 so the first working leg matches the source film.
2. Motion space and display space are separated.
   - `frames[].motionSpaceModelTransform` retains true progressive travel.
   - `frames[].modelTransform` removes only cumulative travel and preserves the local lunge root shift.
   - Suggested app presentation: centered Nex + floor/background scroll opposite motion-space travel.

Human visual acceptance pending.
