## Exact Symptom

See the observed Codex queries below.

## Diagnosis

The source can compile on the developer's newer device while the SDK's newly raised deployment/minSdk target fails older build or runtime matrices.

## Fix

```
Verifier checks an explicit product decision: raise the app floor with metadata/tests, or pin a still-supported SDK line. Check the resolved dependency graph and runtime behavior on the declared minimum platform.
```

## 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.
