# C1126 — Adopt the isolated replay result

## Question

Can the research reproduce its recorded prefix without access to original workspace sources?

## Inputs

```json
{
  "review_sha256": "71d81ab14435c41548152a450e5e382ee3bb3debb6c5e1e5589ba7ec1da91758"
}
```

## Sources

```json
[
  "prep/portable1114_review.md",
  "prep/portable1114_review.json",
  "C1125"
]
```

## Results

```json
{
  "portable_gate": {
    "path": "model/portable_gate_adoption.json",
    "sha256": "4408353c94cec523620ba64c2301b669d71061ddb1470f4c90b3a4cde22d623c",
    "bytes": 421
  }
}
```

## Finding

The isolated prefix replay passes with zero original sources available and unchanged extracted payloads. A separate final ZIP replay remains required after the 200-action seal.

## Reassessment

Audit the sequential questions, reassessments and hash chain through the current prefix.

## Checks

```json
{
  "prefix_pass": true,
  "zero_originals": true,
  "all_snapshots": true,
  "unchanged_payload": true,
  "safe_archive": true,
  "no_mutations": true,
  "negative_control": true
}
```
