# C657 — Complete the admitted Noah–Joseph comparison

## Question

How much of the400 comparison follows from the variant field?

## Inputs

```json
{
  "G2_variants": [
    2298,
    2238,
    2168,
    2108
  ],
  "Joseph_age17": 1898
}
```

## Sources

```json
[

]
```

## Results

```json
{
  "comparison_gaps": [
    60,
    70,
    60,
    210
  ],
  "total": 400,
  "variant_width": 190,
  "endpoint_arm": 210
}
```

## Finding

The source’s400 comparison is the190-wide alternative-date field plus the210 arm to Joseph1898. Its equality to a400 Affliction duration does not identify their event pairs, and the variant positions are not successive Noah deaths.

## Reassessment

Move to the cumulative4900 body and recover all its supplied cuts with one index.

## Checks

```json
{
  "gaps": true,
  "sum": true
}
