# C1497 — Bind the 1260 decompositions

## Question

How does File17 classify 770+490 and 777+483?

## Sources

```json
[
  "File17.md §§8.1,12.1"
]
```

## Opened utc

## Results

```json
{
  "source": "File17 §§8.1,12.1",
  "status": "inferred component structures",
  "equations": [
    [
      770,
      490,
      1260
    ],
    [
      777,
      483,
      1260
    ]
  ],
  "Lamech_role": "777 is MT Lamech lifespan in the scalar bridge"
}
```

## Finding

Both decompositions are inherited source relations; this study tests their placement in the inverse/Babylonian path.

## Reassessment

Scale the duration components, retaining a duration rather than a calendar-date operation.

## Checks
