# C1524 — Build the common refinement of two12600 partitions

## Question

Can the7700+4900 and11270+1330 paths be expressed with all named cuts retained?

## Results

  "lower_merge": 4900,
  "total": 12600
}
```

## Finding

The named chain is7700+3570+1330. Merging at Covenant gives11270+1330; merging at Shem gives7700+4900. These are two cuts of one ordered interval.

## Reassessment

Reconnect that common interval to the existing MT Creation–SP Flood observation.
