## Exact Symptom

See the observed Codex queries below.

## Diagnosis

Monitoring or admin code references server-side metrics/commands that are not defined in the repository.

## Fix

```
Verifier checks the current metric/command and equivalent alert/administration behavior. Check durability, topology-safe routing, and monitoring meaning.
```

## 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.
