## Exact Symptom

See the observed Codex queries below.

## Diagnosis

The local repository can expose the failure, but the decisive repair depends on the current host, package, runtime, or API contract.

## Fix

```
Use the source trail below to align the local install, host, API, or runtime configuration with the current external contract.
```

## 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.
