      1876
    ]
  ]
}
```

## Finding

Cainan is an inserted node at Shelah+130. Its four placements use the two downstream position choices; it does not receive an additional own-Cainan130 shift.

## Reassessment

Generate the complete finite configuration for all three traditions.

## Checks

```json
{
  "literal_match": true,
  "four": true
}
