# C1148 — Express the clipped rows in begetting and remainder coordinates

## Question

How do the three SP lifespan changes split between birth intervals and remaining years?

## Inputs

```json
{}
```

## Sources

```json
[
  "File18 §§2.1.3,3.1",
  "C1143"

## Results

```json
{
  "clipped_row_decomposition": {
    "path": "model/SP_clipped_row_decomposition.json",
    "sha256": "ec2429915a537f5878593c1d589d17cbcc927e5285357521d3a43bfad7a7e0db",

  ],
  "SP_algebraic_remainders": [
    785,
    653,
    601
  ]
}
```

## Finding

The changes split as Jared−100/−15, Methuselah−120/−129 and Lamech−130/−124 in begetting/remainder coordinates. Both components can change when life is clipped, unlike a conserved-lifespan repartition.

## Reassessment

Ask which shared Flood-boundary relations survive this change of row coordinates.

## Checks

```json
{
  "row_identity": true,
  "remaining_counts": true
}
```
