# C1344 — Integrate NT and grouping interfaces

## Question

What precisely does the identical-birth suffix preserve?

## Inputs

```json
{}
```

## Sources

```json
[
  "prep/final_count_family_draft.md",
  "C1320"
]

## Results

```json
{
  "chapter": {
    "path": "draft/08b_NT_grouping.md",
    "sha256": "7c61982062f9f17c4a4ea38b5f0c2ea98099b75be95d916044f0d93018ff5fe3",

  },
  "words": 676
}
```

## Finding

The NT section gives the complete ten-name birth agreement and the lifespan differences it cannot measure. Grouping examples then distinguish preservation of total, duration and reflection.

## Reassessment

Draft the concluding research synthesis and next discriminating question.

## Checks

```json
{
  "ten_names": true,
  "grouping": true
}
