## Exact Symptom

See the observed Codex queries below.

## Diagnosis

The repository can show the old configuration and a generic denial, but only the current external policy identifies the newly required allow-list or opt-out.

## Fix

```
Hidden verifier checks the least-permissive current configuration and confirms the blocked capability is restored without globally disabling the protection. Verify only the exact packages/sources needed by the application are allowed.
```

## 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.
