# V308 Palm Orientation Wrong-Way Gate

V308 is a safety/root-cause gate over V307.

The key correction from the user: thumb up/down is not a general solver rule. In this specific outside-shin grip, thumb-up is a symptom because the palm should be on the outside of the leg. If one MCP-derived palm point is near/on the surface and the opposite MCP-derived palm point penetrates the leg capsule, the hand/palm frame is wrong-way/twisted through the object.

## What changed

- `NEXPROD01_V308_ACTUAL_MCP_PALM_ORIENTATION_GATE` classifies asymmetric MCP-palm penetration.
- `PALM_FRAME_WRONG_WAY_THROUGH_OBJECT` blocks final pre-finger readiness even if the solver-side target-space gate said `GRIP_ENTRY_CONTRACT_PREFINGER_READY`.
- A new `NEXPROD01_V308_FINAL_PREFINGER_TRUTH` global records post-commit truth.
- Finger release remains disabled by default and is impossible while actual MCP orientation gate fails.

## What V308 does not claim

V308 does not yet solve the left hand. It prevents the false positive and proves the root cause: left palm frame is wrong-way through the object after commit.
