# C956 — Whole-family cap prediction

## Question

Does one rule reproduce every SP pre-Noah lifespan?

## Inputs

```json
{}
```

## Sources

```json
[
  "C953",
  "C955",
  "File18 §3.1.3"
]
```

## Results

```json
{
  "predicted_field": {
    "path": "model/sp_cap_prediction.json",
    "sha256": "b1da06e5bc6a867c65b69f9c5bbca6890ee82fff1aa3ae7c19e5b140d08e8b19",
    "bytes": 354
  },
  "lifespans": [
    930,
    912,
    905,
    910,
    895,
    847,
    365,
    720,
    653
  ],
  "clipped_names": [
    "Jared",
    "Methuselah",
    "Lamech"
  ]
}
```

## Finding

The source-qualified minimum reproduces all nine SP lives; only Jared, Methuselah and Lamech are shortened. This is a conditional reconstruction, not a historical direction claim.

## Reassessment

Inspect slack and reduction across unchanged as well as changed rows.

## Checks

```json
{
  "all_rows": true,
  "active_support": true
}
```
