# START HERE — V415 lateral lunge clean right-foot release

Base checkpoint: V414 exact traveling sequence.

V415 is a surgical contact-release cleanup only. The accepted V414 movement order, timing, depth, travel, planted-foot authority and camera-follow are unchanged.

Human-reported defect fixed:
- immediately before the right foot gathered toward the left foot, the right foot made a tiny down/up micro-stamp.

V415 rule:
`right lunge plant -> unload/lift once -> continuous gather to left foot -> plant`.

Patch scope:
- frames 351–375 only;
- deformation-chain `R_Thigh`, `R_Calf`, `R_Foot(parent=R_Calf)` only;
- no other bone quaternion changed;
- no root-motion, camera, timing, left-leg, torso or arm changes;
- 0 live solver calls; no new runtime solver.

Review `diagnostics/v415/V415_CLEAN_RIGHT_FOOT_RELEASE_TWO_LOOP_QA.mp4` first.
For the subtle release, use the 30 fps one-loop QA in the same folder.
