## Interpretation

V307 fixes the previous phantom-marker problem: palm debug/contact points are now derived from actual Index/Pinky MCP roots plus a 20 mm palm offset.

Right side passes the new actual MCP palm gate. Left side no longer false-passes: it fails because the actual index-derived palm point is still inside the leg capsule by about 23 mm while pinky is on surface. Fingers remain blocked.

This is the correct stop: the next solver step must use the new actual MCP palm gate to drive the left wrist/forearm roll or first-contact selection, rather than accepting the old target-space shifted-surface pass.
