# C664 — Recover the13-jubilee household path

## Question

How does Jacob’s lifespan partition the cumulative path to Exodus?

## Inputs

```json
{
  "nodes": [
    2083,
    1936,
    1446
  ],
  "roles": [
    "cumulative Jacob birth",
    "whole-year Jacob-death/Levi-birth boundary",
    "Exodus"
  ]
}
```

## Results

```json
{
  "gaps": [
    147,
    490
  ],
  "49_coefficients": [
    3,
    10
  ],
  "total": 637
}
```

## Finding

The source household boundary partitions637 as147+490, or3|10 jubilee units. Its corporate reading concerns the boundary of Jacob’s household; it does not date every son’s birth to1936. File70’s macro and biographical families are linked through retained junction roles.

## Reassessment

Open Supplement A’s native720/30 family as a test of the same retained-component mechanism.

## Checks
