# C656 — Reconstruct the local Noah/Shem variant field

## Question

Which spacings survive the admitted local gear and lifespan comparisons?

## Inputs

```json
{
  "Noah_G1": [
    2296,
    2236,
    2166,
    2106
  ],
  "Noah_G2": [
    2298,
    2238,
    2168,
    2108
  ],
  "Shem_G1": [
    2146,
    2086,
    2016,
    1956
  ],
  "role": "alternative death coordinates, not successive deaths"
}
```

## Sources

## Results

```json
{
  "gaps": [
    [
      60,
      70,
      60
    ],
    [
      60,
      70,
      60
    ],
    [
      60,
      70,
      60
    ]
  ],
  "G2_minus_G1": [
    2,
    2,
    2,
    2
  ],
  "Shem_minus_Noah": [
    -150,
    -150,
    -150,
    -150
  ]
}
```

## Finding

The admitted alternative-date rows have one60|70|60 shape. The local Noah gear change translates it by2; the Shem comparison translates it by−150. No operation is extended to Creation or the later patriarchs.

## Reassessment

Determine how the supplied Joseph endpoint completes the local Noah400 comparison.

## Checks

```json
{
  "shape": true,
  "local_gear": true,
  "Shem": true
}
```
