# C1051 — Cumulative bases from source lifespans

## Question

Can the base field and clutch be regenerated without supplying their output dates?

## Inputs

```json
{}
```

## Sources

```json
[
  "C1032",
  "File61 §7.5"
]
```

## Results

```json
{
  "generated_field": {
    "path": "model/covenant_cumulative_regenerated.json",
    "sha256": "730c70e013ee3447c79819c0558809ffc1ceb2b439420299b18a08eb3180b26e",
    "bytes": 950
  },
  "base": [
    2435,
    2260,
    2080,
    1933,
    1796,
    1663,
    1526
  ],
  "derived_clutch": 14,
  "derived_half": 7
}
```

## Finding

The source lifespan stack generates all seven boundaries; the regular Levi death then determines the clutch14 and half7. Those shifts are outputs of the coupled source model.

## Reassessment

Derive the clutch from the maximum-envelope formula and identify its forced landing.

## Checks

```json
{
  "base": true,
  "clutch": true,
  "separate_equal_lives": true
}
```
