# C745 — Locate matched-Cainan translation blocks

## Question

Does the familiar430 cumulative alignment extend through the whole matched-state genealogy?

## Inputs

```json
{
  "comparison": "nativeLXXON minus admittedMTON",
  "insertion_support": "Adam throughArphaxad",
  "cumulative_insertion": 460
}
```

## Sources

```json

  ]
}
```

## Finding

The430 alignment is exactly theAdam-throughLamech plateau. Noah-throughArphaxad differs454, and later blocks follow their own source rows. MatchingCainan removes insertion from the comparison but does not turn the entire genealogy into one translation.

## Reassessment

Test pointwise composition of thethree native comparisonfields with all source modes retained.

## Checks

```json
{
  "upper_plateau": true,
  "next_plateau": true,
  "not_global": true,
  "boundary_change": true
}
```
