# V405 ATG Split Squat Standing Reset

V405 is based on V404. User QA identified that the remaining leg-change transition still looked mechanically awkward even after the knee-continuity fix. The requested correction was to let Nex rise into a natural standing pose between the two lunge sides.

V405 keeps V404 timing, lunge peaks, upper-body source-conformity and knee-continuity authority. Only the lower-body transition around the existing neutral timing knots (phase 0/1 and 0.5) is blended toward the Nex FBX natural standing/rest lower-body pose.

Standing reset metrics:
- foot separation: ~0.1305 m
- left knee: ~178.5 degrees
- right knee: ~178.6 degrees

Exact V404 lunge peak frames at phase 0.25 and 0.75 are unchanged. Upper-body world angular drift versus V404 remains below 0.02 degrees. Knee bend-plane continuity remains below 3.91 degrees frame-to-frame.

No knee-drive pose. No new IK profile. No new solver. 720 baked frames. 0 live solver calls. Human visual acceptance remains mandatory.
