## Exact Symptom

See the observed Codex queries below.

## Diagnosis

Local code often type-checks under both old and new framework semantics; the failure depends on the installed framework version and current runtime defaults.

## Fix

```
Verifier checks behavior across multiple requests/build modes, not merely compilation. Check model outputs and save/load behavior, not only construction.
```

## 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.
