# C1141 — Recover the Methuselah baseline from its source death relation

## Question

Can a retained MT/LXX local birth chain account for the lifespan discarded by SP clipping?

## Inputs

```json
{
  "MT_Methuselah_begetting": 187,
  "MT_Lamech_begetting": 182,
  "Noah_to_Flood": 600
}
```

## Sources

```json
[
  "File18 §4A.2",
  "C1140"
]
```

## Results

```json
{
  "baseline_constraint": {
    "path": "model/Methuselah_baseline_constraint.json",
    "sha256": "3e0ae70dac9acb4008d9ddabe4369fad9fe0a997274246020ac165e5ecee9f9e",
    "bytes": 319
  },
  "life": 969,
  "discarded_excess": 249
}
```

## Finding

The supplied MT/LXX death-at-Flood condition recovers969 from187,182 and600, hence the249 excess above SP720. This connects traditions through a local condition while retaining its three source inputs.

## Reassessment

Derive the249 difference directly from the two begetting changes and the inclusive convention.

## Checks

```json
{
  "source_life": true,
  "SP_distinct": true
}
```
