## Question

Does the completed research prefix reproduce without modifying its evidence?

## Inputs

```

## Sources

```json
[
  "VERIFY_THROUGH_C827.json; frozen source manifest"
]
```

## Results

}
```

## Finding

All96 completed steps replay, and all41 source snapshots and current originals match. The primary File52c pin is intact; no recorded second-inversion guard violation occurs.

## Reassessment

Close the independent-review findings and prepare the restart checkpoint.

  "pass": true,
