## Exact Symptom

See the observed Codex queries below.

## Diagnosis

Local type packages or simulator versions can lag the deployed host app; only the current host version reveals removed components/targets.

## Fix

```
Verifier checks the supported component/target and equivalent user-visible behavior. Assert equivalent rendered interaction in the current host.
```

## 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.
