## Exact Symptom

See the observed Codex queries below.

## Diagnosis

The old package/config name is syntactically valid, but current tool packaging and discovery rules live in external release documentation.

## Fix

```
Verifier checks the current package identity/config format and a real transformed output. Check emitted assets and runtime behavior across the supported target.
```

## 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.
