# V364 — Dual hand contact measured to palm/MCP, not wrist

Completed:
- No image or rendering generated.
- Old V346 body, legs, feet, receivers, contact rules, runtime and grip solver are unchanged.
- MediaPipe was run on the user-selected source image, but only 2D source evidence was used.
- Actual FBX hand geometry was read:
  - Hand -> Index1 MCP
  - Hand -> Pinky1 MCP
  - Hand -> Mid1 / palm base
  - Hand -> Index/Pinky midpoint
- Contact reach is measured to the palm/MCP frame, not the L_Hand/R_Hand wrist controller.
- Both hands' palm-center MCP target projects exactly to the source contact point.
- Old upperarm/forearm lengths are preserved.
- PalmBase/PalmIndexBase/PalmPinkyBase targets are added to the two Figure Four peak keyposes so the hand frame has explicit palm authority.

Stop boundary:
This is an IK target patch only. Next step is runtime/Nex QA or generic grip QA from this IK baseline.
