  ]
}
```

## Finding

With the whole birthpath fixed, each death difference is exactly the negative lifespan difference. Noah,Shem and insertedCainan deaths coincide; the other differences follow locally. Birthpath agreement therefore transfers a specific projection of the sources, not every chronological measure.

## Reassessment

Compare matchedCainan cumulativefields to locate the maximal translation blocks.
