# C795 — Separate topology from its measurement weights

## Question

Can one deletion pattern carry different chronology weights without equating them?

## Inputs

```json
{}
```

## Sources

```json
[
  "File18 Cainan; File53 Kainan deletion"
]
```

## Results

```json
{
  "weights": [
    {
      "representation": "head index",
      "removed_weight": 1,
      "unit": "position"
    },
    {
      "representation": "BJ secondary birth path",
      "removed_weight": 57,
      "unit": "years"
    },
    {
      "representation": "File18 regular",
      "removed_weight": 130,
      "unit": "years"
    },
    {
      "representation": "File18 cumulative",
      "removed_weight": 460,
      "unit": "lifespan-ledger years"
    }
  ],
  "unavailable": "No BJ Kainan lifespan is supplied here; no BJ cumulative460 is inferred."
}
```

## Finding

The common operation is contraction of a named path element. Its weight belongs to the selected source representation:1,57,130,460 are not interchangeable conversions.

## Reassessment

Resolve the2450-to2400 relation through exact endpoint roles.

## Checks

```json
{
  "distinct": true
}
```
