# C611 — Explain the3430 cumulative anatomy

## Question

Does the source decomposition2401+1029 have a compact relation to the carrier leg?

## Inputs

```json
{
  "Actual_nodes": [
    4836,
    2435,
    1406
  ],
  "lifespans": [
    175,
    180,
    147,
    137,
    133,
    137,
    120
  ]
}
```

## Sources

```json
[
  "File60 §§9–10; C546; File63 §8"
]
```

## Results

```json
{
  "parts": [
    2401,
    1029
  ],
  "units_of343": [
    7,
    3
  ],
  "whole": 3430,
  "equivalent_forms": [
    "10×343",
    "7×490"
  ],
  "unchanged_inverse_atom": 3430
}
```

## Finding

The Actual lower-leg anatomy is7×343+3×343=10×343=7×490. This explains its7:3 duration partition and links the lifespan sum to the carrier leg. It supplies no new rounded inverse breakpoint at Abraham.

## Reassessment

Test whether the989 Abraham interval similarly organizes the Actual weighted bridge.

## Checks

```json
{
  "anatomy": true,
  "factors": true
}
```
