## Question

## Results

```json
{
  "primary_heads": {
    "MT": 14726,
    "LXX": 13636
  },
  "lower_leg_difference": 910,
  "upper_inverse_leg_difference": -2000,
  "head_difference": -1090,
  "uniform_910_prediction": 15636,
  "LXX_residual": -2000
}
```

## Finding

No. LXX upper leg9150 reverses to5190 versus MT9170→7190, adding−2000. The complete primary head difference is910−2000=−1090, so the shared packet is local.

## Reassessment

Use the independently named LXX Regular head to refine the12600 comparison, without claiming a global cumulative translation.
