# C1177 — Freeze the complete labelled genealogy for the next extension

## Question

Can the pre- and post-Flood rows be tested together without losing count and source tags?

## Inputs

```json
{
  "proposal_packet_sha256": "1421aa3dbef2f870ef256672b2abd931a3562dc997a22a606507ce3e6c58ec5e"
}
```

## Results

```json
{
  "complete_source_rows": {
    "path": "model/complete_source_row_packet.json",
    "sha256": "1bd5961126532673e6fda1535befc5e64cf21d67d01a3c5e78d1a613bbb8ab59",

  },
  "counts": {
    "MT": 19,
    "SP": 19,
    "LXX": 20
  },
  "next_domain": "ordinary rows plus separately tagged SP inclusive counts; no inferred physical remainder for those counts"
}
```

## Finding

The58-row native packet preserves ordinary biographies, SP inclusive exceptions, nominal versus completed Lamech intervals and nativeCainan. It enables a full pre/post-Flood operator comparison under explicit types.

## Reassessment

Check how the source-supported century operation changes its conserved quantity across the Flood.
