# C580 — Join Shem and Flood to the regular chronology

## Question

Does one carrier translation explain both source horizontal bridges?

## Inputs

```json
{
  "upper_pair": [
    5436,
    4836
  ],
  "lower_pair": [
    2006,
    1406
  ]
}
```

## Sources

```json
[
  "File63 §8; C546; latest File52c"
]
```

## Results

```json
{
  "horizontal": [
    3430,
    3430
  ],
  "vertical": [
    600,
    600
  ],
  "carrier_factorization": [
    7,
    490
  ],
  "Actual_anatomy": [
    2401,
    1029
  ],
  "state_note": "Actual4836 anatomy and Rounded4836 endpoint are separately labelled"
}
```

## Finding

The Shem/Flood and Jacob/Conquest pairs form a600-by3430 rectangle. Its3430 also has the earlier Actual anatomy2401+1029 and the Rounded role7×490; these are interfaces through labelled quantities, not an erasure of their states.

## Reassessment

Test the smaller Flood core against the cumulative Levi phase pair.

## Checks

```json
{
  "rectangle": true,
  "carrier": true
}
```
