## Exact Symptom

See the observed Codex queries below.

## Diagnosis

The local workspace gives the symptom and stale integration shape, but the correct repair depends on current official product behavior or recent release notes.

## Fix

```
Verifier accepts a repair record only if it states the current contract and an actionable fix using source-backed product terms.
```

## Avoid

- Changing local code without checking the current external contract.
- Retrying the same install, build, or API call with no version/source change.
- Applying a broad unsafe bypass when a narrow compatibility fix is available.
