# C1035 — The two147 source conditions

## Question

What constraints make the three differently defined rails agree?

## Inputs

```json
{}
```

## Sources

```json
[
  "File60 §2.3",
  "C1032"
]
```

## Results

```json
{
  "rails": [
    147,
    147,
    147
  ],
  "A1_A2_residuals": [
    0,
    0
  ],
  "conditions": [
    "xJ+jCall+callL=L_J",
    "callL+L_L=L_J"
  ],
  "derived_diagonal": "xJ+jCall=L_L"
}
```

## Finding

The biographical147 is supplied; two source conditions make the intergenerational and call-to-death rails equal it. Their difference explains the shared137 diagonal.

## Reassessment

Keep the equality of Ishmael and Levi lifespans separately labelled.

## Checks

```json
{
  "all_rails": true,
  "conditions": true,
  "diagonal": true
}
```
