# V374 — Locked separated front-shin snap checkpoint

Status:
- V373 separated front-shin snap promoted to V374 locked baseline.
- V371 rejected because it collapsed upper/lower hands into the same shoe/foot cluster.
- This root includes collision mesh, generic grip runtime, IK/contact bank, numeric QA, visual Chromium QA assets, and handover.

Accepted contact model:
- lower hand: foot_underside_sole on existing FootShoe proxy
- upper hand: front_lower_shin_above_ankle on existing LowerLeg proxy
- foot↔shin snap separation >= 0.10 m

Next step:
- lock contacts
- solve torso/spine/head/shoulder chain around fixed contacts
- re-solve arms to fixed contacts
- do not move snap points first
