# C1533 — Bind the shared cumulative lives

## Question

Which original source quantities justify theNoah extension in all three MSS?

## Sources

```json
[
  "File18.md §§2–4,6",
  "File51a.md §16.2"
]

## Results

```json
{
  "Noah_lifespans": {
    "MT": 950,
    "LXX": 950,
    "SP": 950
  },
  "Shem_lifespans": {
    "MT": 600,
    "LXX": 600,
    "SP": 600
  },
  "rounding_residuals": [
    0,
    0
  ],
  "domain": "serial cumulativelifespan boundaries"
}
```

## Finding

Noah950 andShem600 are common transmitted lifespan inputs, unchanged by five-year rounding; their cumulative adjacency follows the serial rule.

## Reassessment

Derive eachNoah boundary from its already frozenFlood seam.

## Checks
