# C788 — Transfer the aligned family through rounding

## Question

Do equal births remain equal while cumulative divergence changes locally?

## Inputs

```json
{}

}
```

## Finding

The aligned birth family survives rounding because its source begetting rows agree. Its cumulative divergence changes574→570 through Arphaxad and Shelah27→25, preserving the explanation by different measurements of the same rows.

## Reassessment

Condense the result into an explicit representation map.

## Checks

  "birth_rows_equal": true,
  "cum_head": true,
  "only_two_changed": true
