# C898 — Distinguish retained biography from uniform transport

## Question

Does the outer147000 span force every internal boundary to be P-scaled?

## Inputs

```json
{}
```

## Sources

```json
[
  "File63 §7.8.2 terminal thousandth"
]
```

## Results

```json
{
  "comparison": {
    "source_nodes": [
      148936,
      2083,
      1936
    ],
    "retained_partition": [

    "uniform_P_birth": "47958/23",
    "retained147_preimage": "1449/10",
    "rule": "expand outer body; retain supplied biography as appointed terminal subdivision"
  },
  "artifact": {
    "path": "model/retained_biography_distinction.json",

  }
}
```

## Finding

The source retains2083→1936 as the final147 of147000, giving999×147|147. Uniform P would move2083 to2085+3/23 and make the interval149+3/23. The outer agreement therefore supports retention, not transport of the original internal147.
