# C1267 — Verify the complete NT comparison recurrence

## Question

How do sourceintervals andNT intervalcounts generate thewholecomparisonfield?

## Inputs

## Results

```json
{
  "recurrence": {
    "path": "model/NT_complete_comparison_recurrence.json",
    "sha256": "6ac195aca0970895bd9dfb769be62c8fdb673c2315cb5a606d87bfac05cedc61",
    "bytes": 5613
  },
  "edges": 21
}
```

## Finding

Thecomplete21-edge comparison follows theexistinglocal recurrence. Arphaxad-to-Shelah covers twoNT cells because thecomparison’sshared-name list omitsCainan; retaining140 prevents a falseone-cell identification.

## Reassessment

Examine theentireSP/LXX suffixwherebirthcomparisons coincide.

## Checks

```json
{
  "all_edges": true,
  "Cainan_edge": true,
  "edges21": true
}
```
