# C849 — State the new list-family extension of the grammar

## Question

What has transferred unchanged, and what must be added to the source object?

## Inputs

```json
{}
```

## Sources

```json
[
  "C833–848; Strategy stageH"
]
```

## Opened utc

## Results

```json
{
  "transfer": {
    "path": "model/list_transfer_summary.json",
    "sha256": "62e4c18b5e59ca75bc8be2c620ee822cd8c4d7b978eb5ec526b76817b4e3614f",
    "bytes": 762
  }
}
```

## Finding

The grammar transfers to lists when source rows retain category annotations and declared order. The new explanation identifies the constraints behind equal totals and the information those totals lose; it does not derive the textual counts or their historical intention.

## Reassessment

Freeze the next complete File52c paired-anchor test before execution.

## Checks

```json
{
  "new_constraints": true,
  "limits_present": true
}
```
