}
```

## Finding

Six +100 begetting moves each trade 100 from the remainder and conserve lifespan. Lamech is a separate −24 lifespan change with begetting182 fixed. One source row structure therefore produces two different chronological projections.

## Reassessment

Apply the same row accounting to SP, including its completed-year boundary.

## Checks

```json
{
  "six_repartitions": true,
  "regular600": true,
  "cumulative_minus24": true
}
```
