## Results

```json
{
  "artifact": {
    "path": "draft/Source_Cost_Summary.md",
    "sha256": "5cfdee75efa181881b2232f8e700cb1f41873251ecf0b2e9c3f536ec91e46f14",
    "bytes": 2127
  },
  "words": 316
}
```

## Finding

The source-cost table makes the compression claim assessable without disguising derived summaries or retained loss data as new primitives.

## Reassessment

Adopt the source/status table for the final evidence index.

## Checks

```json
{
  "nonempty": true,
  "eight_families": true
}
```
